[0002] Polypropylene film, also known as polypropylene sheet, is a film material made of polypropylene. One of the main uses of polypropylene film is in the production of OPP tape (scotch tape). Polypropylene film has high strength and durability, as well as excellent transparency and heat-sealing properties, making it an ideal material for producing high-quality scotch tape. To meet usage requirements, slitting machines are typically used to slit the film. However, existing slitting machines are unable to limit the film during feeding, and the slitting tools are mostly fixed, making it difficult to adjust the spacing of the cutting tools, making it difficult to cut protective films of different widths according to production requirements. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) Supports are installed on both sides of the surface of the processing table, and a mounting block is installed on one side of the support. Two limit rods are installed on the surface of the mounting block. When the film passes through the middle of the two limit rods, the limit rings on the surface of the limit rods are adjusted according to the width of the film, so that the limit rings contact with both sides of the film, which plays a role in limiting the film. When unwinding, the cut and fed film is limited to prevent the film from deflecting. An active roller is rotatably installed on the surface of the support, and the lifting block slides inside the mounting groove through a threaded rod. By rotating the threaded rod, the distance between the driven roller and the active roller is adjusted, so that films of different thicknesses can be fed and conveyed, ensuring the stability of film feeding;

[0026] During specific use: the rotating motor 52 on one side of the support frame 51 rotates to drive the driving gear 57 to rotate, and the driving gear 57 drives the feed roller 53 to rotate through the driven gear 58. The surface of the adjusting rod 54 installed on the top of the support frame 51 is slidably installed with multiple sliders 55, and the bottom side of the slider 55 is installed with a slitting blade 56 in contact with the feed roller 53. When the film is transported to the surface of the feed roller 53, the slitting blade 56 is placed on the surface of the film, and the film is cut into strips under the drive of the feed roller 53. Since the slider 55 can slide on the surface of the adjusting rod 54, the slitting blade 56 is driven by the slider 55 to adjust the spacing, and strip cutting of films of different sizes can be achieved according to usage requirements.
