Description

Technical Field

[0001] This application relates to the field of plate tearing machine technology, and more particularly to an automatic plate tearing machine for flexographic plates. Background Technology

[0002] Flexographic printing is an environmentally friendly, low-pressure printing method. Its printing plates are mostly made of photosensitive resin. After exposure and curing, the plate is adhered to the printing plate roller / sleeve using double-sided tape. The double-sided tape used typically has extremely strong adhesion to ensure a secure bond and prevent the plate from peeling off. After use, the printing plate needs to be disassembled by peeling it off the double-sided tape. Currently, after use, the printing plate is usually disassembled manually, which is time-consuming, labor-intensive, and can easily cause occupational injuries. Utility Model Content
