/in /by

To understand the price of canning equipment, first we need to know what specific canning equipment is required for a complete canning production line. Let us briefly understand the specific equipment.

Three-piece can production line equipment classification: Three-piece can production line manufacturing equipment is divided into cutting equipment, forming welding equipment, drying equipment, rolling equipment, slitting equipment, necking equipment, embossing molding equipment, turning equipment Side equipment, capping equipment, can sealing equipment, leak detection equipment, full internal spray equipment, drying equipment, stacking equipment, packing, etc.

 

  1. Empty can preparation equipment mainly includes: cutting equipment, parting equipment, coating scraping equipment

① Cutting board equipment is used to cut the large sheet of tinplate into pieces of the size required for canning or punching. Its process flow is as follows:

Feeding and cutting → finishing

② Scribing equipment is a device for scoring the uncoiling line or slitting line on the can body blank. Its role is to draw a trace of a certain depth on the cut can body material in order to separate the finished can body from the scribe line.The process is as follows:

Feeder → Single sheet feeding and feeding → marking → selection

Scribing equipment is available in automatic or semi-automatic stand-alone form, as well as in combination with can body welding and forming machines.

③ The coating layer scraping equipment is used to partially scrape the surface coating of the cut can body sheet to facilitate resistance welding (the equipment is not needed to leave the paint plate empty). The process flow is as follows:

Feeder → Single sheet feeding→ Scraping → Stacking

The price of the preparation equipment is about: USD10000-70000

 

2. Can body forming welding equipment

Classification of can body forming welding equipment

The price of can body forming and welding equipment is about：USD10000-50000

 

3. Can embossing and expansion equipment

(1) The characteristics of embossing and expansion of the tank The embossing or expansion of the tank can be changed to various cross-sectional (longitudinal or cross-sectional) shapes.

This pot is a fancy pot. Patterned cans can be divided into two types: one is round, which is characterized in that the mouth shape of the lid maintains the original shape of the round can, and the middle part of the can can be changed according to the shape of the user’s requirements, such as barrel shape, drum shape, Vase-shaped, square, polygonal, cone-shaped, etc., this kind of pot is called an embossed pot (formed fancy pot); another shape of the pot is a special shape, which is characterized in that the lid is non-circular, and the pot body and The shape of the lid is basically the same. Common canned food types are: square, rectangle, polygon, trapezoid, pear (horseshoe), oblate, oval, etc. These cans are called irregular cans.

During the expansion process, the formed tank body is slightly stretched, and the stress on the metal reaches the elastic limit of the material. Before resistance welding occurs, the expansion process of the formed tank cannot withstand such a large expansion force, so the formed shape is not flat. The main body of the embossing tank has a large tensile force, and the stress on the metal exceeds the elastic limit of the material, and large tensile deformation occurs. Compared with the original tank, the volume of the tank after embossing can be increased by about 20%. Since both embossed cans and new-shaped cans need to withstand greater expansion force, only welds (such as resistance welding, laser welding, etc.) can meet the expansion requirements. Because the middle part of the embossed tank has a large tensile deformation, there are higher requirements for the coating on the outer surface and the inner side of the printed iron to prevent damage to the printing and coating caused by such deformation. In addition to the expansion method after welding, there is also a bending method before welding. This method is often used in the welding process of tanks. The tank is directly pressed into a special shape and then welded.

The price of can embossing and expansion equipment is about：USD20000-80000

 

Fourth, repair coating equipment

Repair coating equipment is a kind of equipment covering a layer of protective layer on the weld, the protective layer will not damage the content and have corrosion resistance. After welding, there is no tin layer on the weld, and the inner and outer welds are in direct contact with the inclusions or the atmosphere, which is easy to rust, especially the high-content acid and sulfur of canned food that has been processed at high temperatures and can be stored for a long time. There are more stringent requirements, so internal and external welds must be repainted. The recoater equipment consists of a cam body transmission system and a recoater system. The tank conveying system usually has two electromagnetic conveyor belts, which can continuously, smoothly and accurately send the tank into and out of the coating area after welding.

Coating equipment is roughly divided into the following categories:

The price of recoating equipment is approximately:USD5000-20000

 

Five, drying equipment

The coating on the tank must be cured by heating to volatilize the solvent, thereby polymerizing the monomer and obtaining anti-corrosion properties.

Especially for high-temperature sterilized food, its curing requirements are higher. During curing, the temperature of the surface of the tank must not be higher than the melting point of tin, and the coating must not blister or burn. The curing time must be sufficient. The drying equipment consists of a tank conveying system and a heating system. The conveying system usually uses chains, steel belts or belts, etc., with the help of magnetic adsorption, to send the tank into and out of the heating zone. The conveying system is divided into linear conveying and circular conveying, saving space.

The price of drying equipment is approximately:USD5000-15000

 

6. Equipment that can be rolled and typed

The function of tank rolling ribs and separation equipment is to roll reinforcing ribs on the welded tank or to cut the tank into two or three sections. A roll-bead slitting machine cannot complete these two processes at the same time. If necessary, please replace the rolling rib mold or split mold and configure it as a rolling rib splitter or mold splitter. Some assembly machines have multiple stations, which can be equipped with different molds at the same time to complete processes such as beading, parting, flanging, and sealing, and the principles are the same.

The price of can body rolling and separation equipment is approximately:USD8000-30000

Seven, can shrink, flanging equipment

(1) The necking machine reduces the diameter of the end of the tank, which can reduce the material consumption of the tank cover, which is beneficial to the stacking and transportation of the tank.

nice appearance. Constriction is divided into ordinary single necking, large single necking, two necking, three necking, four necking and so on.

The necking method is divided into rolling method and shrinking method. The rolling method is pure rolling in which the inner and outer molds are rotated while feeding in the radial direction. The thin-iron necking and flanging thin necking method can be completed at the same time when winding, which is easy to wrinkle. The shrinking method is directly extruded by opening and closing the inner mold and the outer mold with a cone, and is formed in one operation. Multiple necking requirements are adopted: uniform necking, smooth, no wrinkles, no oxide film and coating peeling at the weld seam of the tank body, no mechanical wiper or multiple stations to perform a single contraction on the inner and outer surfaces of the tank body The can body, the second shrinkable can, three shrinkable cans, and four shrinkable cans.

(2) Flanging machine: Flanging machine is a device that prepares the wound and necking process by squeezing the flanging mold to clean the two ends of the tank to the edges of the required shape and size. Flanging methods are divided into crushing type, rolling type, rotating type and plate edge type. The extrusion flanging uses a flanging die to extend from both ends, and hits the edges of the two ends of the can along the axial direction of the can body, thereby forming flanges at both ends of the can body. Flanging and necking are done at the same time. The principle is the same as the rolling neck. There are two types of rotary flanging: one is the active rotation of the flanging roller, which has various forms; the other is the driving rotation of the flanging roller, and the two motion principles are the same. The flanging die is composed of multiple flanging rollers. The flanging die extends from both ends of the tank body and is fed along the axial direction of the tank body while rotating. Squeeze both ends of the tank to gradually complete the flanging. The flange beads are arranged along the circumference according to certain rules. The larger the tank diameter, the more flanging rolls, and the deformation is uniform and slow. Therefore, the flanging quality is good, which is especially suitable for the flanging of high-speed thin tin cans. Flanging type flanging is used for flanging special-shaped cans. The outer mold fixes the tank, and the inner mold moves from the inside to the outside to complete the flanging. The flanging die is composed of multiple flanging rollers. The flanging die extends from both ends of the tank body and is fed along the axial direction of the tank body while rotating. Squeeze both ends of the tank to gradually complete the flanging.

How much do you know about tinplate cans?

(1) Classification by material

Can be divided into two major categories of steel and aluminum. The steel series mainly includes low-carbon thin steel plate, tin-plated thin steel plate, chrome-plated thin steel plate, aluminized thin steel plate, galvanized thin steel plate, etc .; the aluminum series mainly includes aluminum alloy thin plate and aluminum foil.

(2) Classification by material thickness

For plates and foils. The sheet is mainly used for manufacturing packaging containers, and the foil is mainly a component of the composite material.

 

The development history of metal packaging materials

The application of metal packaging materials began in 1200 AD. At that time, Bohemia, Czechoslovakia produced tinplate, but its production technology was not spread until 1620, when the Grand Duke of Southern Germany obtained the technology. Metal packaging has only begun to be widely used. In the latter part of the 17th century, people began to use tinplate to make metal buckets to hold dry food. In the 18th century, people began to use food cans to store food. In 1809, a chef and confectioner Nicholas Appert in Paris invented a can storage method, that is, to put food in a wide-mouth bottle, cover it with a cork stopper, give enough temperature to heat sterilize and remove the air, then seal Method can save food for a long time without corruption. In 1810, the British Peter Durand invented the technology of storing food in tin cans using the above principle, and tin cans were born. Before the Second World War, with the improvement of rolling technology and the invention of metal can making machines, the output of tinplate increased greatly. After the Second World War, due to the shortage of tin resources, in order to save tin, people developed tin-making materials or tin-free tin-making materials. As a result, poor-thickness tinplate, low-tinplate, and tin free thin steel plate came out one after another. In the 20th century, with the improvement of aluminum metallurgy technology, the improvement of rolling technology and the appearance of aluminum foil, aluminum began to be widely used in the packaging industry.

In recent years, the can-making technology has developed rapidly. It started as a three-piece can consisting of three parts: the can body, the can bottom, and the can lid.Later, the can body and the can bottom joined together and the can lid was composed of two parts. Tablet cans. The traditional three-piece tin soldering can uses tin-lead solder to weld the seam of the can body, which consumes much tin, and the lead content in the solder can contaminate the built-in food. With the appearance of tin free thin steel plate, people have successfully developed seam welding process. The process of seam welding cans is based on contact resistance, electric heating and melting, and then applying pressure to weld the can body. Later, there emerged a bonding can, which uses organic adhesives to bond the can body seam making process. Both of these methods eliminate the pollution of lead to the food in the can, and solve the problem that the tin-free steel plate cannot be tin-welded. They are widely used in the packaging of beer and carbonated beverages. The modern and advanced three-piece can manufacturing methods mostly use the seam welding method and the bonding method. It has broad development prospects, and tin solder cans have been eliminated in advanced countries such as Europe, America, and Japan. With the widespread use of aluminum in packaging, two-piece cans have appeared. Its structural integrity is strong, easy to decorate and print, and soon occupied the beverage packaging market. However, the production of aluminum consumes a lot of electric energy and its high price limits its usage. However, with the continuous improvement of the can-making process, two-piece cans have been successfully produced using tin-plated thin steel plates and tin free thin steel plates, and automated production lines have been used in industrial production to greatly improve the efficiency of can-making( It can reach 400 cans / min; the production speed of two-piece cans can reach 800-1200 cans / min), so the application prospect of metal cans in packaging is still very optimistic.

Why do biscuits generally use tinplate cans?

/in /by

People’s life and production are inseparable from packaging, because packaging has multiple functions. Why do biscuits generally use tinplate cans? Can we understand from the following aspects?

(1) Protection function. The protection function of the packaging is the most basic and the most important function. It should protect the product from damage and loss. In the circulation process of goods, the factors that cause harm to them are: environmental conditions, such as temperature, humidity, gas, radiation, microbial insects, rodents, etc., which may damage the packaging and harm the product; human factors, the goods are transported, During storage, due to careless or improper operation, the goods are damaged by shock, vibration, or fall, or they are crushed due to too many stacked layers. Therefore, according to factors such as the shape, characteristics, transportation environment, sales environment and other factors of different products, the most appropriate materials, reasonable design of packaging containers and technologies should be given to the packaging to provide sufficient protection functions to protect the safety of the products inside, and the special use of dangerous goods Packaging, pay attention to prevent its damage to the surrounding environment and people and creatures.

(2) Convenience function Modern product packaging can bring many conveniences to people, which plays an important role in improving work efficiency and quality of life. The convenient function of packaging should be reflected in the following aspects.

①Convenient production For mass-produced products, packaging should meet the needs of mechanization, specialization and automation of production enterprises, taking into account resource capacity and production costs, and increase labor productivity as much as possible.

②Convenient storage and transportation For the quality and volume (size, shape, etc.) of each packaging container, the convenient loading and unloading of various transportation vehicles should be considered for stacking; also consider that the quality of manual loading and unloading of goods generally does not exceed 40% of the worker’s weight (limited to about 20kg), etc .; at the same time, it should also consider the storage and stacking method of storage and transportation into warehouses, shops, and residences during circulation Indoor decoration and storage during the process.

③ Convenient use of suitable packaging should make consumers feel convenient when opening, using, storing and storing. Such as carton sealed with adhesive tape, cans, spray packaging, portable packaging, etc., in a concise language or icon, to explain the precautions and methods of use to consumers to facilitate the use.

④Convenient handling means that some packages have the function of repeated use. For example, the recycling of various materials, glass bottles for beer and beverages, and the recycling of packaging waste (paper packaging, wooden packaging, metal packaging, etc.) are convenient for environmental protection and conducive to resource conservation.

(3) Selling functional packaging is like a silent salesman. Good packaging can attract consumers ‘attention and stimulate consumers’ purchases. The sales function of packaging is achieved through packaging design. Excellent packaging design, with its exquisite shape, reasonable structure, eye-catching trademarks, decent text and bright colors and other artistic language, directly stimulates the purchase desire of the consumer lunch, and leads to purchase behavior. Some packaging also has potential value, such as beautiful and suitable packaging containers, which can be used to hold other items after the contents are used up. Uniquely shaped containers and beautifully printed decorations can not only increase the selling price of goods, and promote the sale of goods. At the same time, it can also be collected as an art appreciation.

How to choose canning machine and sealing machine?

How to choose canning machine and sealing machine?

(1) Technical requirements for selecting canning equipment

① Whether the sealed tank is an empty tank (open top tank) or a solid tank.

② The shape of the sealed can body and lid.

③ The annual output of the tank (and converted into shift output or output per minute).

④ The size range of the sealed tank (the range of tank diameter and tank height).

⑤ If it is a solid tank, you also need to know the contents and vacuum requirements.

(2) Determination of the type and main parameters of the canning equipment According to the two requirements (1) and (2). in (1), the type of equipment used can be determined.

If it is an empty can or a solid can sealer, whether it is a round can or a shaped can, or whether the shape of the can body and the can lid are consistent. Especially when the shape of the can body and the lid are inconsistent (such as an embossed can), the type of can sealer should be determined according to the shape of the can lid, that is, a canned can or a round can sealer, and then according to the can body The shape of the tank requires the necessary modification of the transport system of the tank body (in general, the design of the tank sealing equipment considers that the shape of the tank body and the lid are consistent, and the difference is only in the size of the tank lid) according to (3) and (4). Two requirements, determine the adaptation range and production capacity of the selected equipment (also consider the matching with the production capacity of other equipment on the production line).

  • Selection of the structure and layout type of the can sealing machine

The actual can sealing machine is usually only vertical due to the need to fill the contents. Empty can sealing machine has horizontal. The distinction between vertical and vertical can be determined according to the working attitude of the can body and the can conveying equipment of other supporting equipment.The horizontal can sealing machine often needs to raise the can body to a higher position, and then rely on gravity. The guide cage dumps the can body to a horizontal state and conveys it to the entrance of the can sealing machine. The vertical can sealing machine does not need to raise the can body, and can use a conveyor belt (or chain) to directly convey the upright can body to the can sealing machine inlet. At present, most of the high-speed can sealing machines are vertical. The vertical can sealing machine has a compact structure and is convenient for maintenance and debugging. It should be given priority when selecting. In the vertical tank sealing machine, whether to choose the sealing wheel type or the track type, the characteristics of the two should be analyzed first. The track type combined machine has a compact structure and a small footprint, but the sealing track is difficult to process, requires high accuracy, and has a high manufacturing cost. At the same time, different tank types cannot be shared. The sealing wheel is simple to process and easy to ensure accuracy.Several tank types can often share one type of sealing wheel, the manufacturing cost is low, and the maintenance and adjustment of the machine are easy and simple.As can be seen from the respective characteristics of the two, the rail type can sealing machine is more suitable Workshop space is limited, and companies that change tanks infrequently use it. In general, more sealing wheel sealing machines are used. The combination of the advantages of the two can sealing machines also has the form of a sealing wheel combined machine, but there is no such product in China. Under the same conditions, the canning machine in the rotating form of the can body should be preferentially selected.The sealing roller of this canning machine can be arbitrarily adjusted with the swing arm, so the diameter of the sealing roller remains unchanged when the tank diameter changes. This allows different tank types to share the same sealing roller. The sealing roller of the eccentric feed can sealing machine can only be adjusted slightly. When the tank type is changed, the sealing roller must be replaced. In the tank body non-rotating can sealing machine, the four sealing roller types are preferred (two for each of the first and second sealing rollers). Because there are many sealing rollers, the crimping quality is high.

(4) Selection of canning machines with different degrees of automation Generally, automatic canning equipment should be selected for large-scale production, and the quality of automatic equipment is stable.

It is not affected by human factors, and the labor intensity of workers is small, and the production capacity is large, so it is more used. For small batches and limited funds, a semi-automatic can sealer can also be used. When the output is not reached, multiple units can be used. Manual can sealing machine is generally only suitable for laboratory use, used for testing can sealing, can also use this can sealing machine to make some sample cans as trial marketing products, so that less investment can be used for market analysis first.

(5) Selection of solid tank sealing equipment In addition to the requirements of vacuum degree, whether to fill with carbon dioxide gas, etc. when selecting solid tank sealing equipment, it is also necessary to consider whether the contents will overflow during the sealing process. Whether the materials are resistant to corrosion and meet food hygiene requirements. Priority should be given to the filling and sealing machine, the reliability of such equipment should be higher than the split equipment, and the cost is lower.

(6) Selection of spray can sealing equipment Spray cans are different from empty cans, and both ends of the can body need to be sealed. So when choosing canning equipment

There are two options. One is to use a horizontal necking, flanging and sealing combined machine.This equipment can simultaneously complete the necking of the tank body and the sealing of the top and bottom cover.It has a compact structure, but its production capacity is low. 60 cans / min, double heads are 120 cans / min; the other option is to use two can sealers to crimp and seal twice, and add a can pouring device and conveying equipment between the two devices.
