China Metal Bucket Making Machine is used to make 10-25L round metal pail, barrels, drums, buckets, such as paint, oil, glue pails. If you want to make different size of such barrels, it just need to change moulds of the machines. The bucket size can be customized according to your needs.

Conical pail 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 should be placed in induction drying oven to dry if it's inner coating or inner powder coating.Afer drying,It will be fed to cooling device to make natural cooling.The cooled can body is then fed to the conical pail combination machine,and the can body is in an upright state going through the uprighting conveyor.The first operation is the can body conical expansion.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 conical expanding mold to make conical expanding.The step 2 is pre-flanging The step 3 is curling.The upper mold is fixed on the machine body,and the lower mold,which is mounted on the CAM,completes the flanging and curling when the CAM is jacked up.The step 4 is beading.After completing the above four steps,When the bottom lid auto feeder detects the can body coming,It will automatically feed one bottom lid to the top of the can body,and then both the can body and the bottom lid will be clamped to seaming machine head to make auto seaming.After bottom seaming, it is fed to automatic double spots ear lug welding machine,through automatic side welding seam indexing,Cam conveyor conveying,mechanic paint breaking,also equipped with automatic ear lugs vibrating discs,finish accurate welding task on conical pail.Then,The pail is fed to handle making and assembly station to finish automatic handle assembly.Lastly,The finished can is conveyed to the automatic leak testing station by conveyor.Through the accurate air source detecting step,The unqualified products will be tested and fed to the fix area.The qualified pails will come to the packing table for the final packaging.
