Problems solved by technology

However, the paper pressing efficiency of the paper pressing device is low, and when there are wrinkles in the paper, the paper after pressing still has wrinkles, and the flatness of the paper is not ideal.
Therefore, existing paper pressing devices for printing machines have the problems of low paper pressing efficiency and unsatisfactory paper flatness after pressing.

Abstract

The invention discloses a paper pressing device with the controllable compression rate for a printing press. The paper pressing device comprises a rack, a paper storing worktable, a paper stack and apaper pressing device body; the rack comprises a pair of front-rear brackets which are arranged in a front-rear symmetrical mode; the front-rear brackets are each in a U shape with an opening being formed downwards; the paper pressing device body comprises a pair of paper pressing supporting plates arranged in a lifting mode, and a pair of pressing rollers arranged in a left-right symmetrical mode; a rotating main shaft is fixed to a center shaft of each pressing roller, the front end and the rear end of each rotating main shaft are connected to rectangular left-right sliding plates in a pivoted mode correspondingly; the pair of left-right sliding plates on the front side is arranged on the paper pressing supporting plates on the front side in a left-right sliding mode, and the pair of left-right sliding plates on the front side and the paper pressing supporting plates on the front side are synchronized or get close to one another; the pair of left-right sliding plates on the rear sideis arranged on the paper pressing supporting plates on the rear side in a left-right sliding mode, and the pair of left-right sliding plates on the rear side and the paper pressing supporting plateson the rear side are synchronized or get close to one another; a pressing roller limiting unit is arranged between the pair of paper pressing supporting plates; and a compression rate adjusting blockis arranged at the lower end of the pressing roller limiting unit in a lifting mode. According to the paper pressing device, the compression rate of the paper stack can be controlled manually, the paper pressing efficiency is improved, and the flatness of paper is ensured.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a paper pressing device with controllable compression rate for printing machines. Background technique [0002] The existing printing machine needs to cut the base paper before printing; when cutting, the base paper (paper stack) needs to be transported to the paper cutting platform, and then the paper is compressed with a paper pressing device before cutting . The existing paper pressing device generally uses two left and right hydraulic cylinders to drive the pressing plate to press the paper. However, the paper pressing efficiency of the paper pressing device is low, and when the paper is wrinkled, the pressed paper still has wrinkles, 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. Contents of the in...
