[0002] Plastic film slitting is the process of cutting wide plastic films into narrower widths according to requirements. This process is widely used in packaging materials, agricultural covering films, industrial films and other fields.

[0003] The existing publication number CN218776691U, entitled "A Plastic Film Slitting Mechanism," includes a frame and a cutter roller. The cutter roller is rotatably and adjustablely mounted on the frame. The cutter roller has multiple sets of cutters along its circumferential direction, each set comprising several cutters. The cutters in the same set are arranged along the axial direction of the cutter roller, and the number of cutters in different sets varies. During the rotational adjustment of the cutter roller, the cutters in different sets are sequentially put into working state. This plastic film slitting mechanism is simple to operate and saves time and labor when it is necessary to slit plastic film into different quantities.

[0004] However, in the above-mentioned plastic film slitting method, multiple sets of cutters on the cutter roller are fixed on the cutter roller, and the interval between the cutters on the cutter roller is fixed and cannot be adjusted. In the later stage, it is impossible to quickly adjust the cutter interval according to the actual cutting needs of the plastic film, and it is not suitable for cutting plastic films of different widths.
