Problems solved by technology

Since the rotation frequency of the cam is fixed on a specific offset printing machine, when the ink supply volume of the ink unit is to be changed, the method of adjusting the gap between the ink fountain roller and the ink fountain doctor blade is usually used. This adjustment is difficult and expensive. Long time, affecting production

Abstract

A swinging controller for the ink-transfer swing drum of offset printer is composed of a programmable legic controller and its relative circuits. Inputting the pre-calculated data to said programmable logic controller can regulate the swinging frequency of said swinging drum, so changing the ink supply.

Description

technical field [0001] The invention relates to an ink supply and transfer mechanism of an offset printing machine, in particular to a swing control device for an ink transfer swing roller in an ink unit of an offset printing machine. Background technique [0002] Driven by its swing control device, the pendulum roller in the ink unit of the offset printing machine swings back and forth between the ink fountain roller and the intermediate ink transfer rubber roller, and crosses contact with the ink fountain roller and the intermediate ink transfer rubber roller, so that the ink fountain roller The ink is transferred to the middle ink transfer rubber roller, and the ink supply volume of the ink unit can be changed by adjusting the swing frequency of the ink transfer pendulum roller or the gap between the ink fountain roller and the ink fountain scraper blade. The existing offset printing machine uses a cam as the swing control device of the ink transfer pendulum roller. The w...
