Printing machine bottom roller dedusting device

Abstract

The invention provides a printing machine bottom roller dedusting device. The printing machine bottom roller dedusting device comprises a bottom roller. The bottom roller is mounted on a bottom roller fixing support through a bottom roller fixing shaft. The bottom roller fixing support is fixed to the bottom roller mounting frame. A dedusting sponge is arranged on one side of the bottom roller and is embedded in a dedusting sponge groove. Dedusting groove fixing plates are arranged at the two ends of the dedusting sponge groove. Adjusting supporting rods are mounted on the dedusting groove fixing plates. The middle of the adjusting supporting rod is mounted on the bottom roller mounting frame through a sliding groove plate. One end of the adjusting supporting rod is rotationally mounted on the dedusting groove fixing plate, and the other end of the adjusting supporting rod is mounted on a spring fixing rod through a spring. According to the printing machine bottom roller dedusting device, the dedusting sponge is arranged on one side of the bottom roller, ink dust on the bottom roller can be removed in real time, the printing quality is ensured, impurities on the bottom roller can be effectively removed through the dedusting sponge in the dedusting sponge groove by soaking the dedusting sponge in 202 hydrogen containing silicone oil, and thus the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a dust removal device for the bottom roller of a printing machine. Background technique [0002] According to the requirements of the State Administration of Taxation, motor vehicle sales invoices must be printed on dry-type carbon paper. The invoice page and the deduction page are printed in four colors. The colors include colorless fluorescent, genuine, tax supervision seal and black invoice code. Under the pressure of the four offset printing bottom rollers, the coating on the back of the paper is very easy to stick to the bottom printing rollers. Therefore, when printing, each color group must send a special person to clean the bottom rollers, and print invoices and deductions. It takes six people to complete the joint. In normal work, some of the printed back layers of the finished products have been reversed and cannot be copied. They can only be discarded, resul...

[0002] According to the requirements of the State Administration of Taxation, motor vehicle sales invoices must be printed on dry-type carbon paper. The invoice page and the deduction page are printed in four colors. The colors include colorless fluorescent, genuine, tax supervision seal and black invoice code. Under the pressure of the four offset printing bottom rollers, the coating on the back of the paper is very easy to stick to the bottom printing rollers. Therefore, when printing, each color group must send a special person to clean the bottom rollers, and print invoices and deductions. It takes six people to complete the joint. In normal work, some of the printed back layers of the finished products have been reversed and cannot be copied. They can only be discarded, causing a lot of waste, low production efficiency, and poor product quality. labor intensive
