Description

Technical Field

[0001] The utility model relates to the technical field of printing and die-cutting, in particular to a size-adjustable printing and die-cutting device for paper. Background Art

[0002] Printing is a technology that transfers ink to the surface of paper, textiles and other materials through processes such as plate making, inking and pressurization to reproduce the content of the original manuscript in batches. Generally, die-cutting devices are also used in printing production. Die-cutting machines are also called beer machines, cutting machines, and CNC punching machines. They are mainly used for non-metallic materials such as self-adhesive labels, EVA and double-sided tapes. Die-cutting machines are important equipment for packaging processing and molding after printing.

[0003] The size of die-cutting knives used in traditional die-cutting production is fixed. When encountering a larger pattern that exceeds the cutting range of the die-cutting knife, a larger die-cutting knife needs to be replaced. When encountering a smaller pattern, a smaller die-cutting knife needs to be replaced. The die-cutting range cannot be changed according to the size of the pattern. This operation method makes it extremely inconvenient to replace the die-cutting knife, which is time-consuming and labor-intensive.
