It is mainly used for die-cutting, creasing and hot stamping operations, laminating and automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc. The working principle of the die-cutting machine is to use die-cutting knife, steel knife, hardware mold, steel wire, and apply a certain pressure through the stamping plate to cut the printed product or cardboard into a certain shape.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
