Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing machines, in particular to an ink scraping component and a printing machine. Background Art
[0002] A gravure printing machine is a machine that uses a gravure plate for printing. The image and text 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. Products produced by gravure printing machines have the advantages of thick ink layer, rich layers, strong three-dimensional sense, and good printing quality. They are mainly used for printing exquisite color pictures, trademarks, decorations, securities and color newspapers.
[0003] When the existing gravure printing machine is in use, the entire surface of the 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 roller is pressed on the back of the paper to transfer the ink in the concave part directly to the paper surface, and finally the printed matter is stacked or rewound by the paper receiving part. However, since the existing machine body lacks a structure to reinforce the scraper and the scraper itself is relatively soft, the scraper may rebound when scraping the ink on the surface of the plate cylinder, causing the ink attached to the scraper to rebound to the surface of the plate cylinder and affect the printing on the paper.
