Technical Field

The invention relates to printing equipment, in particular to an ink distributing roller driving mechanism of an offset press.

Background

An offset printing press is a lithographic printing press in which a printing image is first printed on a blanket cylinder from a printing plate and then transferred to a sheet by the blanket cylinder. The traditional oscillating roller is realized by arranging a corresponding worm and gear transmission component at each oscillating roller in order to realize rotation and axial movement of the traditional oscillating roller, the structure of the traditional oscillating roller is very complex, and the stability and the precision of transmission are not high.

Disclosure of Invention

In view of the shortcomings of the background art, the invention aims to provide the oscillating roller driving mechanism of the offset press, which has a simple structure and reasonable design, and can drive the oscillating roller to rotate and accurately and axially reciprocate.

Therefore, the invention is realized by adopting the following scheme:
