Paper printing flattening device of printing machine

Abstract

The invention discloses a paper printing flattening device of a printing machine, and belongs to the technical field of printing equipment. The problem that a flattening plate of an existing device cannot move is solved. The paper printing flattening device is technically characterized by comprising a workbench and a support, wherein a plurality of supporting legs are mounted at the bottom of theworkbench; the support is fixedly mounted on the upper portion of the workbench; the flattening plate is mounted in the support; a position adjusting mechanism is connected to the upper portion of theflattening plate and mounted on the top of the support; a paper adsorption mechanism is arranged on the left side of the support; and a second guide roller and a first guide roller which are used forguiding paper are sequentially arranged on the upper surface of the workbench from left to right. According to the paper printing flattening device, paper can be heated, the flow speed of steam exhausted from an exhaust port can be controlled through an air pressure adjusting valve, and meanwhile, the height of the flattening plate is adjusted through the position adjusting mechanism, the paper can be flattened conveniently, and the problem that an existing paper flattening device is complex in operation is solved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a paper printing flattening device of a printing machine. Background technique [0002] With the continuous development of the flexible packaging industry, printing factories have higher and higher requirements for the speed of paper gravure printing machines, but the problem of smooth feeding on the existing high-speed paper gravure printing machines has become an important factor affecting the machine speed. At this stage, the main The flattening of the paper is achieved by a flattening roller, but manual assistance is required to avoid folding of the paper. [0003] Chinese patent CN202794054U discloses a paper flattening device for printing machine chain movement, which is composed of a vacuum pump, a quick-plug connector, an air pipe, a pressure equalizing box and a regulating valve. The paper flattening device includes a suction flattening assembly, And the air ...

AI Technical Summary

Problems solved by technology

The invention realizes the flattening of large-format paper through the movement of the sprocket; however, the flattening plate of the device cannot be moved, and when the paper is folded, manual adjustment is required by the staff, which increases the risk of operation. Therefore, we propose a printing machine paper printing flattening device
