[0002] Flexographic printing press is a printing equipment with many advantages, including its flexibility, easy maintenance and high-speed operation capability. It is suitable for a variety of printing materials, can produce high-quality printing, and is easy to operate, reducing the cost of use.

[0003] At present, when a flexible printing plate (called flexographic plate) made of resin material is attached to the surface of a plate roller, a manual plate attaching method is mostly used. Specifically, a tape is first wrapped around the plate roller, and then the plate is attached manually. However, the existing manual operation leads to reduced positioning accuracy of the glue attaching, and bubbles are easily formed on the surface of the plate roller by the tape. In addition, the workload is large, resulting in reduced work efficiency. In addition, uneven force during manual glue attaching can also cause deformation of the printing plate, affecting overprinting, thereby affecting the final effect of the plate attaching.

[0004] In view of this, the inventor specially designed a gluing device for a plate mounting machine, and this case was thus generated. Utility Model Content
