Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, specifically a die-cutting device for producing antistatic PET protective film. Background Technology

[0002] Protective films can be categorized by their use into digital product protective films, automotive protective films, household protective films, food preservation protective films, etc. Functionally, protective films are used to place a layer of film on the physical objects we want to protect. In terms of application scope, protective films can be applied to the surfaces of metal products, coated metal products, plastic products, automotive products, electronic products, signage products, profile products, and other product surfaces. Protective films are a common industrial consumable.

[0003] The cutting blade of the protective film die-cutting device is used to cut the protective film. Because the cutting blade needs to be cut repeatedly, it is prone to wear and needs to be replaced frequently. Traditionally, the connection between the cutting blade and the device is mostly a threaded connection, that is, multiple bolts are set at the connection between the cutting blade and the device to fix the connection. Whenever the cutting blade needs to be replaced, multiple bolts need to be removed, which is inefficient. Utility Model Content
