Working process of automatic round tin can production line
In the working process of the automatic round tank production line,
The cut tank materials are first put into the feeding table of the automatic resistance welder, sucked out by the vacuum sucker, and the tin blanks are sent to the feeding roller one by one.
Through the feeding roller, the single tin blank is sent to the fillet roller for fillet processing, and then sent to the fillet forming mechanism for rounding.The body is sent to the resistance welder and welded after precise positioning.
After the welding is completed, the tank is automatically sent to the rotating magnetic conveyor of the coater for external coating, internal coating or internal powder coating, which can be carried out according to the various needs of customers.Mainly used to prevent the side weld line from being exposed to air rust. The tank is fed into the combination machine, the tank is in an upright state, through the upright conveyor.And by the fixture to the flanging station. The flanging task is accomplished by the collision of the upper and lower flanging molds.
After that, the tank with flange is sent to the automatic lower cover feeder, and the incoming tank is detected by the detection sensor. The lower cover feeder will automatically send the lower cover to the top of the tank, and send the tank and the bottom of the tank to the position below the sealing block. The lifting plate will send the tank and the bottom of the tank to the sealing machine head to seal.With one end stitched.It is sent to the tank body turning machine to turn over the tank body, and then to carry out automatic cap detection and welding.
Then, it is sent to the automatic double-point ear-ear welder, which completes the precise welding task of the small round tank through automatic side weld indexing, CAM conveyor conveying, mechanical paint breaking, and equipped with automatic ear-ear vibration plate.
Finally, the finished product tank is sent to the automatic leak detection station by the conveyor.
After accurate air source detection, unqualified products are detected and pushed to the fixed area. Qualified products will come to the packaging workbench for final packaging.

The canbody welder is at the heart of any three-piece can production line. It forms the body blanks into their basic shape and welds the seam overlap. Our Superwima welding principle requires only a minimal overlap of a few tenths of a millimeter. Optimum control of the welding current combined with precision-matched pressure on the overlap. Since the launch of the new generation of welders, customers all over the world have confirmed today their considerable satisfaction on an outstanding and a high machine reliability combined with an economical and an efficient production. New industrial standards have been set in the manufacture of canbodies worldwide.

Effective protection of the weld seam is crucial to the quality of a three-piece can. That’s why we offer a broad range of seam protection technologies and systems. After welding, the next step in the manufacture of a quality can is the application of a durable protective layer to the inner and outer seams. We supply fully automated powder-coating or wet-lacquering systems for inner and outer seams. Our seam protection systems can be customized to all system configurations, production speeds and canbody sizes. They guarantee easy, clean operation and low powder or lacquer consumption.
