SATELLITE TYPE ANHYDROUS OFFSET PRINTING UNIT WITH VARIABLE PRINTING REPETITION LENGTH

摘要

Disclosed is a satellite type anhydrous offset printing unit with variable printing repetition length, comprising a rack (1) on which a central roller (2) as well as a plurality of rubber blanket rollers (3) and plate rollers (4) having variable sizes are mounted. Each rubber blanket roller is fitted to the central roller, the distance between the axis of each rubber blanket roller and the central roller can be adjusted; each rubber blanket roller is fitted to one plate roller, the distance between the axis of each plate roller and the corresponding rubber blanket roller can be adjusted; each plate roller is provided with an ink supply system, and the distance between each ink supply system and the corresponding plate roller can be adjusted. The plate rollers and the rubber blanket rollers in the printing unit can be replaced, thereby solving the problems of fixed printing repetition length and limited adaptive range of the printing order in the prior art.
