A printing machine for steel plate printing

Abstract

The invention discloses an embossing machine used for embossing a steel plate. The embossing machine comprises a rack, an embossing roller, a transfer printing roller, a supporting roller and a carrier roller, wherein an ink box and a scraping plate are arranged above the embossing roller; the ink box comprises a shell and a porous humidity absorption medium; a slit is formed in the bottom of the shell; the upper end of the porous humidity absorption medium is located in the shell; the lower end of the porous humidity absorption medium penetrates through the slit to be located outside the shell and is in contact with the surface of the embossing roller; an ink collection groove parallel to the axis of the embossing roller is formed in the scraping plate; ink recycling containers are arranged at the two ends of the ink collection groove; an ink flow increasing pipe is arranged above the ink collection groove. According to the embossing machine used for embossing the steel plate, ink can be uniformly coated on the surface of the embossing roller and the excessive coating degree of the ink is reduced; the ink can be continuously recycled and the degree of spot forming when the ink is dried is reduced, so that the working frequency of cleaning work of the scraping plate is reduced; the utilization rate of the ink is improved, the working efficiency is improved and the labor efficiency is reduced.

Description

technical field [0001] The invention relates to a printing machine for steel plate printing, which belongs to the technical field of steel plate printing processing. Background technique [0002] In the prior art, the technological process of steel plate printing mainly includes: firstly, surface treatment is carried out on the steel plate, then ink is applied according to the design and pattern requirements, and finally the ink is dried and cured by drying equipment. Among them, the process of coating the surface of the steel plate with fixed pattern pattern ink is particularly critical. For the specific process, please refer to the steel plate printing color coating continuous production line disclosed in Chinese patent document CN103332004A and the steel plate printing machine disclosed in Chinese patent document CN208248293U, mainly including frame, printing Roller, transfer roller, support roller, support roller and scraper; printing roller, transfer roller, support rol...

AI Technical Summary

Problems solved by technology

[0003] During the above printing ink application process, it is necessary to continuously apply ink to the printing roller, scrape off excess ink through the scraper, and then apply the ink on the printing roller to the transfer roller through the contact between the printing roller and the transfer roller. On the printing roller, and then printed on the surface of the steel plate through the transfer roller; when the kinematic viscosity of the ink coated on the printing roller is small, the ink is more likely to be overcoated, and the supply rate of the ink is simply reduced , it may cause local insufficient ink to cause missing printing; and when the ink is excessive, it is easier to accumulate ink on the scraper, so it needs to be recycled to prevent the ink from spilling and polluting the working environment, printing equipment and printing steel plate, but on the other hand, the ink It contains a large amount of volatile solvents, so the ink accumulated on the scraper is easier to dry and deposit to form ink spots, which is not only difficult to clean but also increases the consumption of ink, so that the scraper needs to be replaced regularly and the ink spots are cleaned, which affects work efficiency and increased labor intensity
