[0016] 1. The linear drive mechanism drives the linear moving plate to move toward the support shaft, and the linear moving plate drives the receiving plate to move toward the support shaft. When the receiving plate passes under the feed box, the loading mechanism pushes the bottom metal plate in the feed box into the positioning groove, thereby realizing automatic loading of the metal plate. It is only necessary to stack the metal plates in the feed box, thereby reducing the workload of workers;

[0017] 2. When the receiving plate drives the metal plate to move to the bottom of the support shaft, the forming mechanism forms the metal plate in the positioning groove and wraps it on the support shaft, and the welding mechanism welds the formed metal sleeve on the support shaft to realize the integration of forming and welding of the metal plate, reduce the manufacturing steps of canned packaging cans, and improve the production efficiency of canned packaging cans;

[0018] 3. After the linear moving plate moves to contact with the fixed plate, the linear moving plate cannot move further. This time, the guide block overcomes the elastic force of the compression spring 1 and moves relative to the linear moving plate. The guide block drives the follower push block to move relative to the fixed push block. Under the guiding action of the guide shaft 2, the fixed push block overcomes the elastic force of the compression spring 2 and pushes the fixed push block upward. The fixed push block drives the receiving plate to move upward. The receiving plate cooperates with the support shaft to clamp the metal plate in the positioning groove, thereby preventing the metal plate from moving during forming and welding.

[0019] 4. After the welding of the metal sleeve on the support shaft is completed, the linear drive mechanism drives the linear movable plate to move away from the support shaft and reset. When the linear movable plate moves away from the support shaft and detaches from the bottom of the support shaft, the material return assembly pushes down the welded metal sleeve on the support shaft, and the welded metal sleeve falls from the blanking notch, thereby completing the unloading of the metal sleeve. The present invention can realize automatic loading, forming into a round sleeve, welding and material return of the metal plate through one reciprocating movement of the linear movable plate and the receiving plate, thereby completing the welding of the packaging can and improving the welding efficiency of the canned packaging can.

In the initial state, the receiving plate 105 and the linear movable plate 104 are located below the feed box 103, and the metal plates are stacked in the feed box 103. The motor 204 drives the screw rod 203 to rotate, and the screw rod 203 drives the guide block 302 to move through a threaded transmission. Under the guiding action of the guide shaft 202, the guide block 302 drives the linear movable plate 104 to move through the compression spring 303, and the linear movable plate 104 drives the receiving plate 105 to move. When the receiving plate 105 passes under the feed box 103, the receiving plate 105 drives the vertical slider 404 and the discharge block 406 to move toward the support shaft 108, and the discharge block 406 moves the lowermost part of the feed box 103. The metal plate is pushed out from the discharge port 401, so that the metal plate falls into the positioning groove 106, thereby realizing automatic loading of the metal plate. It is only necessary to stack the metal plates in the feed box 103, thereby reducing the workload of workers. The receiving plate 105 drives the metal plate to move under the support shaft 108. After the linear movable plate 104 moves to contact with the fixed plate 201, the linear movable plate 104 cannot continue to move. This time, the guide block 302 overcomes the elastic force of the compression spring 1 303 and moves relative to the linear movable plate 104. The guide block 302 drives the follower push block 304 to move relative to the fixed push block 305. Under the guiding action of the guide shaft 2 306, the fixed push block 305 overcomes the elastic force of the compression spring 2 307 and pushes the fixed push block 305 upwards. The fixed push block 305 drives the receiving plate 105 to move below the support shaft 108. The material plate 105 moves upward, and the material receiving plate 105 cooperates with the support shaft 108 to clamp the metal plate in the positioning groove 106, thereby preventing the metal plate from moving during forming and welding. After the material receiving plate 105 and the support shaft 108 clamp the metal plate, the cylinder 1 504 extends, and the cylinder 1 504 drives the U-shaped forming block 505 to move upward, and the U-shaped forming block 505 cooperates with the support shaft 108 to form the metal plate into a U shape, and then one of the cylinders 2 604 extends, and under the guidance of the guide shaft 3 603, one of the cylinders 2 604 drives one of the forming blocks 602 to move, and one of the forming blocks 602 fits one side of the U-shaped metal plate onto the support shaft 108, and then the other cylinder 2 604 extends, and under the guidance of the guide shaft 3 603 Under the guiding action of , another cylinder 2 604 drives another forming block 602 to move, and the other forming block 602 fits the other side of the U-shaped metal plate onto the supporting shaft 108, thereby overlapping the two ends of the metal plate to facilitate subsequent welding, and the motor 2 903 drives the screw rod 2 902 to rotate, and under the guiding action of the linear slide 901, the rotating screw rod 2 902 drives the mounting block 802 to move through thread transmission, and the mounting block 802 drives the mounting frame 803 to move, and the mounting frame 803 drives the welding roller 805 to move, and the welding roller 805 cooperates with the fixed welding rod 801 to clamp the overlapping part of the metal sleeve, and the welding device welds the overlapping part of the metal sleeve through the welding roller 805 and the welding rod 801, thereby completing the welding of the metal sleeve.After the metal sleeve on the support shaft 108 is welded, the motor 204 drives the screw rod 203 to reverse, and the screw rod 203 drives the guide block 302 to move in the opposite direction and reset through thread transmission, and the compression spring 303 resets first. At this time, the guide block 302 moves and resets relative to the linear movable plate 104, and the guide block 302 drives the follower push block 304 to move in the opposite direction relative to the fixed push block 305, and the compression spring 2 307 drives the guide shaft 2 306 to move downward and reset, and the guide shaft 2 306 drives the receiving plate 105 to move downward and reset, and the receiving plate 105 and the support shaft 108 release the welded metal sleeve, and then the guide block 302 drives the linear movable plate 104 to move in the opposite direction, and the linear movable plate 104 moves away from the support shaft 108, and the linear movable plate 1 04 drives the pull rod 703 away from the support shaft 108 until the protrusion at the end of the pull rod 703 contacts the stripping plate 701, and the linear moving plate 104 has been lowered away from the support shaft 108. At this time, the pull rod 703 overcomes the elastic force of the tension spring 702 and drives the stripping plate 701 to move. The stripping plate 701 pushes the metal sleeve on the support shaft 108 off the support shaft 108, thereby causing the welded metal sleeve to fall from the blanking notch 102 and complete the blanking until the receiving plate 105 moves back to the bottom of the feeding box 103. The present invention can realize automatic loading, forming into a round sleeve, welding and stripping of metal plates through a reciprocating movement of the linear moving plate 104 and the receiving plate 105, thereby completing the welding of the packaging can and improving the welding efficiency of the canned packaging can.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
