Problems solved by technology

[0002] For film double-sided adhesive products, film double-sided adhesive products will have knife marks left on the lower release paper after punching, and the upper release paper of the film will be torn off before laminating with other parts. The positioning hole of the pattern paper and the steel sheet are bonded by hot pressing. Due to the high temperature, the edge of the film will easily expand and overflow, and it will be stuck in the knife mark. After the lamination is completed, the film will be broken when the lower release paper of the film is torn off The edge of the film will be uneven or deformed if the knife print is stuck, which will affect the product quality

Abstract

The invention discloses a cutter-mark-free die cutting device for a film. The device is characterized in that a PET protecting film transferring manner is adopted, so that problems such as that lowerrelease paper is adhered into a cutter mark produced by die cutting after being thermally pressed and broken during being torn can be prevented; a die cutting mechanism is designed; a cutter mark preventing mechanism is arranged; a sunken part at the cutter mark can be recovered in an air blowing manner, and the problem of the cutter mark is decreased; the influence of the cutter mark in subsequent PET protecting film adhering process and the thermal pressing process can be reduced. Additionally, a wedge-shaped cutter mark block is utilized for guiding and a film adhering guide wheel supportsduring the adhering of the PET protecting film, so that the film can be accurately adhered, and bubbles and the like produced in the film adhering process can be reduced; the subsequent thermal pressing fitting accuracy and precision can be ensured; and the overall accuracy of the product is ensured.

Description

technical field [0001] The invention relates to the technical field of die-cutting, in particular to a film die-cutting device without knife marks. Background technique [0002] For film double-sided adhesive products, film double-sided adhesive products will have knife marks left on the lower release paper after punching, and the upper release paper of the film will be torn off before laminating with other parts. The positioning hole of the pattern paper and the steel sheet are bonded by hot pressing. Due to the high temperature, the edge of the film will easily expand and overflow, and it will be stuck in the knife mark. After the lamination is completed, the film will be broken when the lower release paper of the film is torn off If the knife print is stuck, the edge of the film will be uneven or deformed, which will affect the product quality. [0003] Therefore, the present invention provides a knife-free film die-cutting device to solve the problems raised in the back...
