Description

Technical Field

[0001] The utility model relates to the technical field of transmission mechanisms, in particular to an anilox roller transmission device for a flexographic printing machine. Background Art

[0002] The gear drive of the anilox roller in a flexographic printing press plays a crucial role in the printing process. Through a precise meshing mechanism, the gear drive ensures stable operation and precise control of the anilox roller. This mechanism not only improves the overall operating efficiency of the press but also significantly enhances print quality.

[0003] Specifically, the gear drive ensures uniform and stable ink transfer even at high speeds. Through the tight coordination of the gears, the concave carriers on the anilox roller's surface precisely transfer and control the ink, achieving ink storage, uniformity, and transfer functions while avoiding ink streaks and ghosting. Furthermore, the gear drive effectively overcomes the "ink flying" phenomenon, significantly increasing the speed of the printing press and thus improving production efficiency and capacity.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: the gear is first sleeved on the outer wall of the anilox roller shaft end, and then connected to the roller shaft through a pin shaft. However, during the meshing process of the gears, relative sliding and rolling will occur between the tooth surfaces. This continuous friction will cause gradual wear of the tooth surface material. When foreign impurities enter and mix with it for a long time after meshing and rotating, it will also cause wear on the tooth surface. When the wear reaches a certain extent, the gear needs to be replaced. To replace the gear, the anilox roller needs to be disassembled from the equipment before the pin shaft can be removed and the gear can be taken out from the outside of the roller shaft. The process is cumbersome and troublesome. After installing the new gear, the anilox roller needs to be reinstalled and re-debugged, which adds operating steps and makes the process more cumbersome and troublesome. Utility Model Content
