[0002] In many fields such as electronics and optics, PTFE protective films are widely used for surface protection of various products due to their excellent chemical stability, low friction coefficient and good insulation, etc. With the rapid development of related industries, higher requirements are put forward for the processing precision and efficiency of PTFE protective films.

[0003] Traditional PTFE protective film cutting methods, such as manual cutting or cutting with simple mechanical cutters, have many drawbacks. Manual cutting is not only inefficient, but also difficult to ensure the accuracy and consistency of the cutting size, which easily causes material waste. Although mechanical cutter cutting improves the efficiency to a certain extent, due to the special properties of PTFE material, the cutter wears out quickly, resulting in unstable cutting quality, and the debris generated during cutting easily contaminates the protective film, affecting the product quality. In addition, some existing cutting equipment often cannot meet the cutting needs of PTFE protective films of different shapes and sizes, and has poor flexibility. The present application provides a PTFE protective film cutting device to solve the problems raised in the background art. CONTENT OF THE INVENTION
