Control and Regulation of Following Pressure Regulating Device in Offset Press

Abstract

In this paper, the single and double eccentric combination of pressure regulation device in the offset press was as the object. A closed loop control system of printing pressure and a following pressure regulation device were designed. The rotation angle of eccentric bearing in plate cylinder and the length change of regulating screw were worked out by means of the vector relationship of pressure regulation. The influence on printing quality from the pressure regulation device was analyzed, and it provided a certain basis for the regulation and control of printing pressure.
