Automatic small square can production line
1.What’s the small square can?
It is made of three pieces of metal sheet (mostly tinplate), the can body, the bottom and the lid. The can is square shaped. The small square can range: capacity 1-5L, diagonal 160-220mm, height 120-360mm.
2. Small square can fully automatic production line operating process:
Firstly, Put the cutted can body tinplate to the feeder of fully automatic resistance welding machine. It will be feeded separately into the feedstock roller by vacuum sucker unit. Single metal sheet will be made bending process by sending from feedstock roller to deflection roller, then will be sent into the forming unit to be curled to round can body. The can body is fed into the resistance welding machine, and the resistance welding is carried out after accurate positioning. After welding, the can body is automatically fed into the receiving frame of the coating machine. There are two kinds coating machine: spraying type and rolling coating type, which are available for users to choose. It is mainly used to prevent the welding seam from contacting air and causing rust. The can body is fed to the combination machine of big square can body, Which will be in an upright state through the can standing device, and then the can body is sent to the automatic indexing unit in the first procedure by clamping device.The second procedure is expanding and forming, When it reaches the can feeding platform, the can body is sent to expanding station to finish the square forming procedure. The third procedure is the can top flanging, the fifth procedure is the can bottom flanging.The bottom flanging: the can will be sent to the flanging bottom die lied on the upper part of the machine by tray platform to make it. The top flanging:the upper cylinder will press the can body to the position of top flanging die to make it. The top and bottom can body flanges are each driven by four cylinders. The fifth procedure is automatic induction of lid feeding and automatic sealing. After the above five procedures, the can body is rolled out to the turning over device to reverse the can up and bottom. and the automatic induction of lid feeding and sealing of the can is carried out again.

4. Advantages and disadvantages of the full-automatic production line of small square can
Advantages: the whole production line adopts automatic computer programming control system, fully realizing the full automatic assembly line work.Only 1-2 workers are needed to complete the operation of the entire production line.The whole production line has fast production speed, high production efficiency, automatic fault detection system and low rejection rate.
Disadvantages: compared to semi-automatic production line, the initial investment capital is larger. For the start-up enterprises, It is recommended to use semi-automatic production line with less capital in.
5. Comparison of machines of Yixin and its counterparts
Yixin machines: all stations of the whole production line are processed with high hardness and imported wear-resistant materials. The imported guide rail and profile are combined with precise coordination of servo motor to ensure a fast conveying system. Six-wheel can sealing machine head, The sealing quality is stable and fast .At the same time, the sealing machine head adopts special design, which has the characteristics of low noise and high efficiency.
Counterparts machines: most of the production line is made of domestic materials, common profile and domestic guide rail, combined with stepping motor,Which will be in some lack of stability and accuracy.Can sealing machine head only has four rollers, quality and speed will have a certain impact .At the same time the machine head adopts the old design, the production noise is bigger.
6. Applicable and applied industries
This production line is suitable for the production of square metal cans used in food, medicine, chemical, paint, edible oil and other industries.It can also be used in food can, paint can, edible oil can, paint can, lubricating oil can, etc.
7. Which countries and regions are applicable
Applicable to countries or regions where labor is difficult, unstable, or highly paid. Examples: Malaysia, Indonesia, Philippines, Vietnam, Thailand, India, dubai, Brazil, venezuela, etc.
Applicable to countries or regions with high output and high product quality.For example: Saudi Arabia, dubai, Russia, Canada, South Korea, Turkey, Europe, the United States and so on.
