Adjustable rolling pressing structure for printing

Abstract

The invention discloses an adjustable rolling pressing structure for printing. The adjustable rolling pressing structure comprises a main shaft, a printing roller and an isolation roller. The main shaft is of a cylindrical structure. Under the action of supporting abutting of the two ends of a tapered sleeve, the printing roller can be quickly coaxial with the main shaft, so that mounting and dismounting are convenient, the replacement of the printing roller can be quickly completed, the replacement efficiency is relatively greatly improved, and the replacement difficulty is relatively greatlyreduced. Moreover, due to the blocking function of the tapered sleeve, glue can be prevented from flowing into an isolation sleeve, and the sanitation of the surface of the main shaft can be guaranteed indirectly by the isolation sleeve. Meanwhile, because the contact area between the tapered sleeve and the printing roller is small, later cleaning is relatively more convenient even when glue flows into a lap joint position.

Description

technical field [0001] The invention relates to the field of printing, in particular to an adjustable rolling structure for printing. Background technique [0002] For printed printing, it is often necessary to use a printing roller. The traditional printing roller has its own main shaft, so it is not only troublesome but also expensive to disassemble in practice. Therefore, there are many split structures on the market, namely the main shaft and the printing roller. Two parts, the printing roller is fixedly sleeved on the main shaft. When the printing pattern needs to be replaced, only the printing roller needs to be replaced. However, the current printing roller installation is mostly fixed by many screws, and the overall disassembly efficiency is low. SUMMARY OF THE INVENTION [0003] In order to overcome the disadvantages of the above-mentioned situation, the present invention aims to provide a technical solution capable of solving the above-mentioned problems.
