Abstract

The invention discloses a paper pressing device for a printing machine. Two sets of compressing assemblies are arranged on the side portions of a machine body. Each compressing assembly comprises a rotary arm which can rotate, a drive cylinder which can drive the rotary arm to rotate and a rolling body which can make contact with paper. The two sets of compressing assemblies are located on the two sides of the machine body correspondingly and are mutually symmetrical. Two sets of buffering assemblies are arranged on the bottom of a chamber of the machine body. Each buffering assembly comprises a guide track which is arranged in the horizontal direction, a supporting frame which can do linear reciprocating motion along the guide track, an elastic unit which can extend and retract in the horizontal direction and an abutting and connecting unit which can make contact with the outer circumferential surface of the corresponding rolling body. The two sets of buffering assemblies are located on the two sides of the chamber of the machine body correspondingly and are mutually symmetrical. The paper pressing device can effectively improve the paper pressing efficiency and the paper flatness after the paper is compressed.

Description

technical field [0001] The invention belongs to the technical field of printing machines, and in particular relates to a paper pressing device for printing machines. Background technique [0002] The existing printing machine needs to cut the base paper before printing, and when cutting, the base paper (or paper stack) needs to be transported to the paper cutting platform, and then the paper is pressed with a paper pressing device, and then the cut. The existing paper pressing device generally uses two left and right hydraulic cylinders to drive the pressing plate to press the paper. [0003] However, the paper pressing efficiency of the existing paper pressing device is low, and when there are wrinkles in the paper, the paper still has wrinkles after pressing, and the flatness of the paper is not ideal. Therefore, the existing paper pressing device for printing machines has the problems of low paper pressing efficiency and unsatisfactory paper flatness after pressing. C...
