Technical Field

[0001] The invention mainly relates to the technical field of self-adhesive printing, and in particular to a self-adhesive printing device. Background Art

[0002] The self-adhesive printing machine is a device mainly used for label printing. Since label products have diverse requirements in terms of aesthetics, anti-counterfeiting and personalization, the printing process also includes post-printing processing units such as die-cutting, punching, creasing, hot stamping, laminating, embossing, compounding, gluing, folding, cutting sheets, and striping, which can meet different customization needs and improve the quality of labels.

[0003] In the process of printing the self-adhesive label, dust is unavoidable on the surface of the self-adhesive label. Since the printing plate cylinder is in contact with the surface of the self-adhesive label for a long time to print on it, the surface of the printing plate cylinder is easily adhered to dust, and it is necessary to stop the machine regularly to clean the printing cylinder, which leads to defects that affect the printing efficiency of the printing machine. Summary of the invention

[0004] The present invention mainly provides a self-adhesive printing device to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:
