Description
Technical Field
[0001] The utility model relates to the technical field of gravure printing machines, in particular to a gravure printing machine. Background Art
[0002] The gravure printing machine is mainly used for printing patterns on the surface of roll decorative paper. During the printing process, the pattern roller contacts the ink in the ink cartridge while rotating, so that the surface of the pattern roller can be coated with ink. The ink remains in the concave holes on the surface of the pattern roller. With the extrusion of the embossing roller, the ink in the holes can be transferred to the surface of the material, thereby achieving the effect of printing on the material.
[0003] After long-term use, the scraper of the existing gravure printing machine will cause certain wear and tear, and it will not be able to fit closely with the printing roller, which will affect the scraping effect of the scraper and thus affect the printing effect. In addition, due to the different types of ink, the ink stained by the scraper will mix with the new ink, which may change the color of the ink. However, the replacement of the scraper is relatively cumbersome and inconvenient for the staff to replace it quickly. Utility Model Content
