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 a prelimiting device for a printing machine. The paper pressing device comprises a machine frame, a paper placing workbench, a paper pile, a paperpressing device body and the prelimiting device. The machine frame comprises a pair of front and rear supports which are arranged in a front-rear symmetrical mode, and 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 pair of rectangular limiting driving groovesarranged in a left-right symmetrical mode are formed inside the paper pressing supporting plates, rectangular sliding wire grooves are formed in the lower ends of the front side wall and the rear sidewall of the limiting driving grooves, and front-rear-through rectangular avoiding grooves matched with the sliding wire grooves are formed in the lower ends of the oppositely-close side walls of thepair of limiting driving grooves, rectangular limiting plates are arranged in the limiting driving grooves in a lifting mode, a pair of left-right symmetrical prelimiting columns are formed on the upper end face of a lifting bottom plate, and rectangular top plates are formed in the middles of the prelimiting columns. By means of the paper pressing device, the paper pressing efficiency can be improved, and paper flatness is ensured.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a paper pressing device with a pre-positioning device for a printing machine. 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 invent...
