Description

Technical Field

[0001] The utility model belongs to the technical field of knife molds, in particular to a knife mold for producing acrylic foam reticulated protective films. Background Art

[0002] The die cutter used in the production of acrylic foam textured protective film is a mold specially designed for cutting this special material. The shape, size and structure of the die cutter will be customized according to the specific specifications, thickness and required cutting pattern of the protective film.

[0003] Since acrylic foam textured protective film has specific physical and chemical properties, such as stickiness, softness and wear resistance, the material and design of the die cutter need to be able to cope with these characteristics to ensure that there is no adhesion, tearing or damage to the protective film during the cutting process. Therefore, the die cutter is usually made of high-strength, high-wear-resistant materials and has a sharp cutting edge to achieve precise cutting results.

[0004] When the knife die is used, because the knife die does not have a splicing mechanism, most users can only use a single knife die to cut the acrylic foam textured protective film. When customers need to produce acrylic foam textured protective films of different shapes, they can only be produced separately and cannot be produced at the same time, which has low flexibility. In addition, when the user uses the knife die to cut the acrylic foam textured protective film through a die-cutting machine, warping may occur, resulting in inaccurate cutting. In view of this, we propose a knife die for the production of acrylic foam textured protective film. Utility Model Content
