Description

Technical Field

[0001] The utility model relates to the field of rubber rollers, in particular to an ink transfer rubber roller for flexographic printing. Background Art

[0002] With the development of flexographic printing technology, the ink transfer structure of narrow-width flexographic printing machines has been continuously improved and simplified. The original anilox roller gear drives the rubber roller gear to drive the rotation of the rubber roller and transmit ink. Due to the complexity of the transmission structure, when cleaning the rubber roller, it is easy to cause the rubber roller gear to rust and bring difficulties to the cleaning work.

[0003] The industry removed the rubber gear and replaced it with a direct pressure friction transmission structure between the rubber roller and the anilox roller. Although the structure became simpler after this method of improvement, new problems emerged, such as: 1. During the printing process, the rubber roller transmission often slipped, the ink transfer was interrupted, and the printing was short of ink. 2. Or the pressure between the rubber roller and the anilox roller was reduced. Although the rubber roller slip problem could be solved, the gap between the rubber roller and the anilox roller was too small or there was no gap, which made the transmission ink insufficient, resulting in a serious problem of short of ink printing.
