Research of Unpowered Cleaning Equipment for Blanket Cylinder

Abstract

In order to enhance the cleaning speed, reduce the cleaning cost and solve other problems of the existing cleaning equipment for blanket cylinder, we put forward a new-type unpowered cleaning equipment for blanket cylinder after a comparative analysis between powered spurt brush type cleaning equipment and unpowered cleaning cloth type cleaning equipment with respect to their structures and characteristics. Furthermore, after we study the cylinder structure of printing press and the cleaning effect of the existing cleaning equipments, a spurt brush type is proposed. We obtain the optimal pressure of this cleaning equipment through repeated experimental analyses on the pressure exerted by brush roller on blanket cylinder. The velocity parameter is determined by analyzing the cleaning principle of brush roller.
