[0002] A PET film cutting device with a clamping function is a device specially designed for cutting polyethylene terephthalate (PET) film, and the device has a clamping function to ensure the stability and accuracy of the cutting process. The device is usually composed of a frame, a slide, a roller assembly, a transfer assembly, a fixed seat, a rotating rod, a clamping assembly, a cutting table, a cutting assembly, etc. Through the coordinated work of each component, efficient and accurate cutting of the PET film is achieved.

[0003] The patent with announcement number CN211761804U discloses a PET film cutting device, including a base, a fixed plate, a threaded hole, a threaded rod, a pressure plate, a fixed assembly, a slide plate, a slider, a bolt hole, a fastening bolt, a guide rod, a cutting knife, a stepped hole, a limit plate and a feed trough. Fixed plates are fixedly installed on both sides of the top of the base, and threaded holes are correspondingly opened on both sides of the top of the two fixed plates. Threaded holes are installed in each of the threaded holes. Step holes are opened at the tops of the two pressure plates corresponding to the threaded rods. The utility model has a scientific and reasonable structure and is safe and convenient to use. The connecting rod is inserted into the mounting hole, and the clamp is moved by rotating the adjusting nut. The clamp moves and cooperates with the base to clamp the table top of the workbench, thereby fixing the base, passing the PET film through the feed trough, rotating the threaded rod, and the threaded rod is screwed into the threaded hole. The movement of the threaded rod drives the pressure plate to move, thereby pressing the PET film.

[0004] This application improves a PET film cutting device with a clamping function by rotating the adjusting nut to move the clamping plate, and the movement of the clamping plate and the base cooperate to clamp the table top of the workbench, thereby fixing the base, passing the PET film through the feed trough, rotating the threaded rod, and screwing the threaded rod into the threaded hole. The movement of the threaded rod drives the pressure plate to move, thereby achieving the effect of clamping the PET film. However, this device can only clamp and cut the PFT film.
