Description

Technical Field

[0002] Traditional die-cutting refers to a cutting process for the post-processing of printed materials. The die-cutting process can make printed materials or other paper products into die-cutting knife plates according to pre-designed graphics for cutting. Traditional die-cutting production uses die-cutting knives to combine into die-cutting plates according to the patterns required by product design. Under the action of pressure, printed materials or other plate-shaped blanks are rolled and cut into the required shape or cut marks. In the processing process of the existing anti-adhesion high-speed die-cutting mechanism suitable for adhesive-backed films, waste will be generated when the adhesive-backed film is die-cut using the die-cutting structure.

[0003] The accumulation of a large amount of waste will affect the die-cutting process of the adhesive-backed film. Stopping the machine to clean the waste will cause the die-cutting speed to drop significantly, which is not convenient for the die-cutting process of the adhesive-backed film. In addition, some of the adhesive-backed film that has been cut during the die-cutting process is not completely cut, and there is a certain adhesion between it and the waste. The staff needs to manually separate them later, which increases the workload. Utility Model Content
