Description

Technical Field

[0001] The utility model relates to the technical field of coloring of printing presses, in particular to a coloring device of a gravure printing press. Background Art

[0002] The gravure printing machine is a machine that uses gravure to print. The image part of the printing plate is concave, while the blank part is on the same plane as the outer circle of the printing plate cylinder. When the gravure printing machine is printing, the entire printing plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a scraper, leaving the ink on the image part, and then the paper is passed, and the impression cylinder is pressed on the back of the film, so that the ink in the concave part is directly transferred to the film, and finally the printed matter is piled or rewound after winding. The gravure printing machine adopts the round-to-round direct printing method. The printing plate is directly made on the printing plate cylinder, and the ink is applied by immersion or inkjet, and there is no ink uniforming mechanism. Due to the thick ink layer, a drying device is required when using highly volatile quick-drying ink.

[0003] At present, a Chinese patent with announcement number CN202223544208.9 discloses a coloring device for a gravure printing machine. When the printing plate cylinder is used to color the paper, the utility model scrapes the ink on the surface of the printing plate cylinder through a scraper arranged on one side to ensure the printing quality. However, when the scraper is scraping the ink, some ink will fall into the guide plate arranged at the lower end for diversion buffering to avoid falling directly into the ink tank, splashing the ink, and adsorbing it onto the printing plate cylinder or paper, affecting the coloring quality. After the scraper is used for a long time, some residual ink will solidify on the scraper, affecting the use of the scraper. By starting the electric lifting rod, the scraper is driven to move, contacting the blade scraper and the cleaning sponge to clean the blade, so as to ensure the subsequent scraping quality and improve the practicality of the coloring device.

[0004] During the production of existing packaging bags, it is necessary to perform coloring and printing on the surface of the packaging bags, and the above-mentioned comparative document can ensure the quality of subsequent ink scraping and improve the practicality of the coloring device. However, during use, the above-mentioned device cannot efficiently perform coloring and printing on the packaging bags, which is not conducive to controlling the quality of coloring and printing of the packaging bags, and the above-mentioned device cannot dry the surface of the packaging bags after coloring and printing, which is not conducive to drying the ink and affects the printing quality. Therefore, we need to provide a coloring device for a gravure printing machine. Utility Model Content
