Description

Technical Field

[0001] The utility model relates to the technical field of roller printing rotators, in particular to a roller printing rotator of printing equipment. Background Art

[0002] The drum printing rotary is a rotary printing machine in the printing press. The rotary printing machine uses a ring-shaped printing plate to perform continuous printing during the printing process. The drum is the main axis, which rotates continuously along the movement direction of the paper, and prints the ink through the printing plate onto the paper to form patterns, texts and other printed products.

[0003] After a long period of operation and use, the printing roller in the roller printing rotator will gradually wear out or malfunction. At this time, it needs to be inspected and maintained to ensure the printing quality. However, many current printing rollers adopt an integrated design, which means that the entire roller is an indivisible whole and lacks detachability. This design may have the advantages of simplifying the process and reducing costs during manufacturing, but it brings many inconveniences in the actual inspection and maintenance process. Once a problem occurs with the printing roller, the staff often needs to disassemble the entire roller printing rotator, or use complex and time-consuming processes to repair the roller, which not only increases the difficulty and time of maintenance, but may also affect the overall performance of the printing equipment.

[0004] Therefore, it is necessary to provide a new roller printing rotator of printing equipment to solve the above-mentioned technical problems. Utility Model Content
