Description

Technical Field

[0001] The utility model relates to the technical field of printing machinery, in particular to an anilox roller transmission mechanism. Background Art

[0002] The anilox roller is a core component of a flexographic printing press, primarily responsible for evenly transferring a fixed amount of ink to the printing plate, creating various patterns on the printed workpiece. Due to varying printing requirements, the anilox roller requires frequent replacement, primarily based on a combination of factors, including the shape of the ink holes, the number of lines on the anilox roller, and the material coated or sprayed on the roller surface.

[0003] In the existing transmission mechanism of the anilox roller, the motor power is generally transmitted to the roller shaft of the anilox roller through a gear transmission mechanism. Therefore, during use, if the anilox roller needs to be replaced due to different printing patterns, the gear transmission mechanism must first be disassembled, and then the entire roller body must be replaced. After replacement, the gear transmission mechanism must be reinstalled, making this series of operations cumbersome and complicated, reducing work efficiency. In addition, the gear transmission mechanism also generates relatively large noise and vibration during operation. Utility Model Content
