Fixed bottom printing unit and its printing machine

Abstract

The invention provides a fixed printing unit, which includes a frame, a vacuum transmission mechanism, an embossing roller, a typesetting roller, an anilox roller, a lifting mechanism and a separation mechanism arranged on the frame; the typesetting roller and The anilox roller is fixed on the frame, the embossing roller is suspended on the frame and located above the typesetting roller, the embossing roller is arranged on the vacuum transmission mechanism, and the lifting mechanism is connected to The vacuum transfer mechanism and the separation mechanism are located at one end of the embossing roller. The fixed bottom printing unit of the present invention can effectively reduce the working center of gravity of the fixed bottom printing unit by setting the separation mechanism and the lifting mechanism, and avoid the occurrence of Larger vibrations will cause the printed characters to be skewed or misplaced, and the running speed of the fixed bottom printing unit will be increased, thereby improving production efficiency and reducing production costs.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a fixed bottom printing printing unit of corrugated cardboard and a printing machine thereof. Background technique [0002] The history of the development of printing in my country begins with block printing in the Sui Dynasty. Because it cannot flexibly organize and change fonts, one block can only print books with one typesetting. When it is necessary to print a large number of books with different typesets, it needs Corresponding to the production of a large number of engravings, so the process is extremely heavy. In order to solve such defects, in the Song Dynasty, Bi Sheng invented movable type printing, that is, engraving individual characters on one piece of mud (wooden or bamboo), and then passing each character between each character. Flexible combination and transformation, so as to print books with different layouts. However, in modern times, printing is not only use...

AI Technical Summary

Problems solved by technology

Due to the high overall height of the traditional fixed bottom printing machine, the working center of gravity is also high. When performing fast printing, the body will shake a lot due to the fast operation of the machine, resulting in skewed or Misalignment will seriously affect the quality of printed matter, reduce production efficiency, and increase its production cost
