Description

Technical Field

[0001] The utility model relates to the technical field of printing press equipment, in particular to a plate hanging tool for a printing roller of a rotary printing press. Background Art

[0002] Labels, as the printing industry calls them, are mostly printed materials used to identify product information and are often self-adhesive on the back. However, some labels are printed without adhesive and are also called labels. Labels with adhesive are commonly known as "self-adhesive labels." Labels require printing during the production process. Before using existing printing rollers, double-sided tape must be applied to the rollers in circles. After the tape is applied, one end of the resin printing plate must be manually aligned and attached to the roller. Finally, the entire resin printing plate must be manually attached to the roller.

[0003] For example, Chinese patent publication number CN220095914U discloses a plate-hanging fixture for a printing roller of a rotary printing press, comprising a base plate, a fixed support frame and a movable support frame for supporting the printing roller, a positioning assembly provided on one side of the printing roller, a cleaning assembly provided on the other side of the printing roller, and corresponding first and second friction discs provided on both sides of the printing roller, respectively, wherein the first friction disc is connected to the output end of a drive motor;

[0004] The technical solution recorded in this proposal is to set up a fixed support frame and a movable support frame to support the printing roller. The movable support frame can adjust its position according to the length of the printing roller so that the first friction disc and the second friction disc are tightly fitted with the printing roller. The drive motor is started to drive the first friction disc to rotate, thereby driving the printing roller to rotate, making it convenient for staff to stick double-sided tape and resin printing plates. The operation is convenient and saves labor for manually rotating the printing roller. However, when this solution is in use, the friction disc does not have a locking function after rotation, which causes the printing roller to easily rotate when the user sticks the printing plate, affecting the sticking effect.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a plate hanging tooling for the printing roller of a rotary printing press is provided, in order to achieve the purpose of having more practical value. Utility Model Content
