[0002] Label printing machines, also known as self-adhesive printing machines, are used to print labels and trademarks. With the continuous maturation of digital printing technology and the gradual expansion of its application areas, high speed and high quality are the development direction of label printing. Rotary printing will become the main production method for label printing. During the label production process, the rough edges of the label rolls need to be trimmed.

[0003] Traditional label printing machines and burr-cutting structures are fixedly installed as an integral part of the printing machine body and cannot be adjusted in position. This makes it impossible to cut label rolls of different widths. As a result, during the burr-cutting process, the cutter may cut over the line, cutting off the label pattern on the paper roll and causing the label product to be scrapped. Furthermore, the cut edges are prone to being carried away with the label roll, affecting subsequent production. Utility Model Content
