With the prosperity of the economy, people's living standards continue to improve, production technology is developing better and better, people are more and more demanding on the use of their time, and in life, we have higher and higher requirements for equipment. Decorative film is a common daily necessity for people. Decorative film has the advantages of good transparency, good moisture barrier, excellent heat resistance, easy use, low price, etc., and is widely used in all walks of life. In the production process of decorative film, the existing decorative film is made into a large roll, so it needs to be cut according to the actual situation when used.

[0003] In the existing devices for cutting decorative films, the decorative film is simply fixed and then cutting begins. However, unstable fixing may lead to inaccurate cutting. At the same time, during the cutting process of the decorative film, since the decorative film is soft and thin, it is easy to warp and wrinkle before and after cutting, which will affect the cutting. Direct cutting may easily lead to uneven cutting, affecting the aesthetics of the decorative film after cutting. Utility Model Content
