[0002] The main component of PVC film is polyvinyl chloride. Common products include plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. The market prospects of PVC film are very promising. In fact, with the development of the times, PVC is gradually winning people's favor with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. PVC film can be divided into hard film and soft film. Soft PVC film is generally used for floors, ceilings and the surface of leather. However, since the soft PVC film contains softeners, it is easy to become brittle and difficult to preserve, so its scope of use is limited. Hard PVC film does not contain softeners, so it has good flexibility, easy to shape, not brittle, non-toxic and pollution-free, and has a long shelf life. Therefore, it has great development and application value. In the existing PVC film production, the slitting device needs to be assisted by staff to cut the material when it is necessary to cut the material, and the cutting shape is relatively single, which affects the overall use effect and overall efficiency of the device.

[0003] For example, the utility model with announcement number CN216836463U discloses a slitting machine for PVC film. The technical solution of this patent includes two fixed bases, the upper surfaces of the two fixed bases are fixedly connected by a connecting plate, and slitting grooves that penetrate the inside of the connecting plate are opened on both sides of the connecting plate. A movable groove is opened inside the top of the connecting plate, and a slitting device is slidably connected inside the movable groove. A slide groove is opened between the slitting groove and the movable groove, and an electric lifting rod located in the slide groove is fixedly installed at the bottom of the slitting device, and a slitting cone located in the slitting groove is fixedly installed at the bottom of the electric lifting rod. During use, this device requires manual assistance to adjust the width of the material, and the cut shape is single. Therefore, a slitting device for PVC film production is proposed.
