[0008] As a preferred technical solution of the utility model, a winding roller is installed between the two groups of side plates, and a winding motor is installed on the outer side wall of the side plate.

[0009] As a preferred technical solution of the utility model, the support roller is located on the side close to the material roll.

[0010] As a preferred technical solution of the utility model, the top height of the support roller is higher than the bottom height of the cutter.

[0011] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:

[0012] 1. The cutter movement and adjustment are controlled by the bidirectional lead screw. The drive motor drives the bidirectional lead screw to rotate. The moving sleeve block 1 and the moving sleeve block 2 move in opposite directions under the thread transmission of the bidirectional lead screw, so as to adjust the distance between the two sets of cutters according to the required cutting size. There is no need for personnel to manually adjust the position of each cutter. The operation is quick and effective to improve production efficiency.

[0013] 2. Through the setting of the support roller, the electric push rod controls the slider to slide in the slide groove, and the slider drives the support roller to move. The support roller stretches the protective film passing from above to make it flat, preventing the conveyed protective film from being loose and affecting the slitting quality.
