Abstract

The invention relates to a paper pressing device before printing. The paper printing device comprises a machine shell, a first press roll, a second press roll, a third press roll, a fourth press roll, a first connecting rod, a second connecting rod, a first screw rod and a second screw rod. The first press roll, the second press roll, the third press roll and the fourth press roll are all located in the machine shell in a rolling mode through rotating shafts. The first press roll and the second press roll are correspondingly arranged up and down, and the third press roll and the fourth press roll are correspondingly arranged up and down. The first connecting rod connects the rotating shaft of the first press roll and the rotating shaft of the third press roll. The second connecting rod connects the rotating shaft of the second press roll and the rotating shaft of the fourth press roll. According to the paper pressing device before printing, the flatness of pressed paper is guaranteed, and the pressing speed is high, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a paper pressing device before printing. Background technique [0002] The printing paper needs to be flattened before printing to ensure the flatness of the paper during the printing process and prevent the printing machine from jamming due to uneven wrinkles. Existing paper pressing mainly depends on the pressing plate, which has the following defects: on the one hand, the flatness of the paper after pressing cannot meet the requirements; on the other hand, the efficiency of paper pressing is not high, resulting in a decrease in printing efficiency. Contents of the invention [0003] To sum up, in order to solve the existing technical problems, the technical problem to be solved by the present invention is to provide a paper pressing device before printing. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a paper ...
