What’s the rectangular 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 50-190mm, height 80-350mm.

Rectangular can fully automatic production line operating process

First place the cut can body materials into the automatic resistance welding machine’s feeding table, Suck by the vacuum suckers,send the tin blanks to the feeding roller one by one.through the feeding roller, the single tin blank is fed to the rounding roller to conduct rounding process, then it will be fed to the rounding forming mechanism to make rounding.The body is fed into the resistance welding machine and make welding after the accurate positioning. After welding, the can body is automatically fed into the rotary magnetic conveyor of the coating machine for outer coating, inner coating or inner powder coating, Which depends on customer’s various need.It is mainly used to prevent the side welding seam line from being exposed in air and rusting.The can body is then fed to the small rectangular can combination machine, and the can body is in an upright state going through the uprighting conveyor. It is fed to the first automatic side welding seam indexing station by the clamps.The second station is square expanding.When the can body is in position, on the can body lifting tray which is controlled by a servo motor, and the can body is sent by this lifting tray to the square expanding mold to make square expanding.The third station is to make can body lower flanging.The bottom flanging: the can will be sent to the lower flanging mold lying on the upper part of the machine by lifting tray to make it. The fourth station is to make can body upper flanging.The upper flanging:the upper cylinder will press the can body to the position of top flanging mold to make it. Both the upper and lower can body flanging is each driven by four cylinders. The fifth station is automatic bottom seaming. After the above five steps,the can body will be reversed up and down by a body turner then make top seaming,this process is the same as the bottom seaming process.Lastly,the finished can is fed by conveyor to automatic leak tester station.After accurate air source inspection, unqualified products are detected and pushed to a fixed area, and qualified products will come to the packaging workbench for the final packaging.

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.

Comparison of machines of ISHIN 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.
