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.
