[0002] Cutting machines are widely used in industries such as textiles, clothing, leather, and paper. One of the core components is the needle roller, also known as the needle cylinder, which is a metal cylinder with steel needles planted on its surface. In the production process of plastic films that need to be punched, a plastic film punching device uses the needle roller to punch holes in the film. There are many types of needle rollers, including a structural form with needles directly installed on the roller or cylinder, and a structural form with a sleeve with needles sleeved outside the roller.
