[0034] When the first motor 6 is started, the rotating shaft 7 drives the rotating rod 16 to rotate, so that the protective film can move on the outer surfaces of the round roller 15 and the rotating rod 16 .

[0035] Among them, a No. 2 motor 17 is fixedly installed on the top of the right side of the casing 1, and a threaded rod 18 is fixedly sleeved on the other end of the output shaft of the No. 2 motor 17. The left end of the threaded rod 18 penetrates the casing 1 and extends to the interior of the casing 1 and is movably connected to the right side of the mounting plate 2.

[0045] The working principle and use process of this utility model:

[0046] First, the operator starts the first motor 6, which will cause the rotating shaft 7 to drive the rotating rod 16 to rotate, so that the protective film moves along the outer surfaces of the round roller 15 and the conveying roller 29. Before the trimming operation begins, the dual-axis motor 23 is started, which will cause the rotating rod 24 to drive the inclined plate 22 to rotate. When the inclined plate 22 rotates to an inclined angle, it will realize the function of guiding the waste edge to the bottom of the inner cavity of the casing 1. Then, the No. 2 pneumatic cylinder 13 is started, which will cause the trimming knife 14 to move vertically downward.

[0047] When the width of the trimming needs to be adjusted, the No. 1 pneumatic cylinder 8 is started to move the vertical rod 9 to the left. At this time, under the limiting action of the vertical slot 12, the two oblique rods 10 and the two rectangular blocks 11 will be pulled to move toward each other, so that the rectangular block 11 drives the No. 2 pneumatic cylinder 13 and the trimming knife 14 to move together, changing the distance between the two trimming knives 14 to achieve the purpose of adjusting the trimming width. When the trimming operation is completed, the dual-axis motor 23 is started to make the rotating rod 24 drive the inclined plate 22 to rotate, and finally the inclined plate 22 rotates to the same plane as the compression plate 21, and then the No. 2 motor 17 is started to rotate the threaded rod 18, so that the sliding block 19 moves horizontally to the left along the limiting rod 3, and at the same time drives the connecting rod 20 to make the compression plate 21 and the inclined plate 22 move vertically downward along the inner cavity of the casing 1, and finally completes the compression function of the waste edge, thereby increasing the storage capacity of the protective film waste edge inside the casing 1.
