Description

Technical Field

[0001] The utility model relates to a die-cutting device, in particular to a die-cutting device without a knife stamp, and belongs to the technical field of die-cutting devices. Background Art

[0002] Die cutting is a post-printing processing technology, which is mainly used to cut materials such as paper, plastic, metal, etc. according to preset shapes and sizes. The die-cutting machine uses steel knives, hardware molds or steel wires (or templates carved from steel plates) to apply a certain amount of pressure through the stamping plate to roll and cut printed products or cardboard into a certain shape. Die cutting can be used for full-cut and half-cut cutting, as well as embossing and hot stamping operations, laminating, automatic waste discharge, etc. It is an important equipment for post-printing packaging processing and molding. Die cutting is widely used in packaging, printing, electronics, medical and other fields to produce cutting products of various shapes and specifications.

[0003] During the use of the existing die-cutting device, there are knife marks on the surface of the products produced. Since the silicone oil film around the knife marks is damaged after being subjected to pressure, the glue on the surface of the product is in direct contact with the inside of the release paper. Therefore, during long-term storage, the product will fit more and more tightly with the release paper and cannot be easily separated, which reduces the product quality and affects the normal use of the product. Therefore, a die-cutting device without knife marks is proposed. Utility Model Content
