[0002] Plastic protective film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. In the production process of protective film, in order to adjust the width of the protective film, the protective film needs to be cut to obtain the final product.

At this time, the plastic protective film contacts the cutter 5, and the user drives the winding roller 3 and the plastic protective film to rotate by starting the servo motor 16. At this time, the cutter 5 can cut the plastic protective film. After cutting is completed, the second electric push rod 18 can be started again to drive the T-shaped frame 19, the movable plate 15 and the winding roller 3 When the cutter 5 needs to be replaced, first turn the button cap 85 to separate it from the screw rod 84, and then move the screw 84 to disengage it from the through hole 83.

When slitting the protective film, it is often necessary to cut the protective film into multiple strips of different widths according to needs. Therefore, the adaptability of the device is poor and has certain usage limitations.
