A printing press device and a printing machine

Abstract

The invention discloses a stamping device. The stamping device comprises a cylindrical roller, a roller height adjusting device, a printing plate, a base and a power device, wherein the roller is opposite to the printing plate; a channel through which the printed material passes is reserved between the roller and the printing plate; the roller is fixedly arranged on the base by the roller height adjusting device; the self height of the roller is changed under the action of the roller height adjusting device; the base is subjected to reciprocation movement under the driving of the power device. Through the adoption of the stamping device, the pressure among the printed material, the stamping device and the printing plate can be increased; the stamping device is capable of uniformly stamping, so that the printing quality is improved; meanwhile, due to the design of the roller, the printing efficiency can be improved.

Description

technical field [0001] The invention relates to an embossing device, in particular to an embossing device in line contact with a substrate, and also to a printing machine using the embossing device. Background technique [0002] The printing process is to place the substrate between the press device and the printing plate, relying on the pressure provided by the press device to transfer the graphics on the printing plate to the substrate. In the existing technology, the printing press device often uses a flat plate device, so that the substrate and the flat press device are in surface-to-surface contact, and then rely on the pressure between the flat press device and the printing plate to complete the printing process. Because the substrate printed in this way is subjected to a large area of ​​uniform pressure during the printing process, it is very easy to cause shallow force in the inking process. When printing more delicate or small-area patterns, it is very easy to cause...

AI Technical Summary

Problems solved by technology

Because the substrate printed in this way is subjected to a large area of ​​uniform pressure during the printing process, it is very easy to cause shallow force in the inking process. When printing more delicate or small-area patterns, it is very easy to cause the pattern The fonts and patterns on the substrate are not clear, especially after the ink layer is enlarged, the graphics on the substrate are more likely to become smaller and blurred

At the same time, the flat printing press device cannot adjust the pressure during printing for changes in the thickness of different substrates

[0003] When improving the existing printing equipment, the method of increasing the printing pressure is often used. However, when the pressure of the printing seat is too high, it is easy to cause the phenomenon of the pressing device to die, and the long-term pressurization will cause mechanical damage in the printing device. The casting breaks or deforms, rendering the entire press useless
