[0048] In summary, during use, place the tinplate substrate under the guiding roller 2 on one side of the workbench 1 and let it pass under the guiding roller 2 on the other side, and then wind it up through an external device. The guiding roller 2 can play a role in guiding the tinplate substrate. Before winding, trimming operation can be carried out on it. Start the servo motor 47 through an external power supply. When the servo motor 47 works, it will drive the first sheave 431 to rotate, and then drive the rotating rod 43 to rotate through the transmission of the first belt 432. When the rotating rod 43 rotates, it will drive the first threaded rod 42 and the second threaded rod 44 to rotate. When the first threaded rod 42 and the second threaded rod 44 rotate, they will drive the adjacent thread sleeves 45 to move relatively. When the thread sleeves 45 move relatively, they will drive the fixed rod 46 to slide in the inner cavity of the sliding port 31. At this time, the distance between the movable plates 5 can be adjusted, and the L-shaped cutting knife 7 will also move relatively therewith, so that the trimming position can be adjusted. When the movable plates 5 move relatively, they will also drive the square rod 65 to move in the inner cavity of the square tube 64 through the movable rod 66 and the fixing plate 661. After moving to a suitable position, the servo motor 47 can be stopped, and then the driving motor 62 can be started through an external power supply. When the driving motor 62 works, the output shaft end thereof will drive the second sheave 621 to rotate. When the second sheave 621 rotates, it will drive the square tube 64 to rotate through the second belt 622. The rotation of the square tube 64 will drive the square rods 65 at both ends of the inner cavity to rotate. When the square rods 65 rotate, they will drive the adjacent movable rods 66 to rotate. When the movable rods 66 rotate, they will drive the rotating rod 67 to rotate. The rotation of the rotating rod 67 will drive the moving plate 69 to move up and down back and forth under the guiding action of the limiting telescopic rod 691 through the swing rod 68.

The rotation of the square pipe (64) will drive the square rods (65) at both ends of the inner cavity to rotate. When the square rods (65) rotate, they will drive the adjacent movable rods (66) to rotate. When the movable rods (66) rotate, they will drive the rotation of the rotating rod (67). The rotation of the rotating rod (67) will drive the moving plate (69) to move up and down back and forth under the guiding action of the limiting telescopic rod (691). At this time, the L-shaped cutting knife (7) can be driven to move up and down back and forth to realize the edge trimming operation of the tinplate substrate, and the setting of the L-shaped cutting knife (7) can cut off the cut-off scraps, which is convenient for the staff to collect them.
