Description

Technical Field

[0001] The utility model relates to the technical field of ink scraping for printing presses, in particular to an ink scraping device for 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 passing through the film, 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 product is stacked 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 dipping or inkjet, and there is no ink distribution mechanism.

[0003] The Chinese patent with the announcement number CN202320653760.7 currently discloses an ink scraping device for a gravure printing machine, which avoids deformation of the scraper due to excessive resistance when the distance between the scraper and the printing roller is small, and avoids insufficient ink scraping when the distance between the scraper and the printing roller is large, thereby facilitating sufficient ink scraping and improving the ink scraping effect.
