Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing machines, in particular to a gravure direct embossing printing device. Background Art

[0002] The gravure printing machine covers the entire surface of the printing plate with ink, then uses a special ink scraper to remove the ink from the blank area, leaving the ink only in the cells of the graphic part. Then, under greater pressure, the ink is transferred to the surface of the substrate to obtain a printed product. Gravure printing is a direct printing method, so it is also called a gravure direct embossing printing device.

[0003] After searching, the applicant found that a Chinese patent disclosed a "dust removal device for the embossing roller of a gravure printing machine", and its publication (announcement) number is "CN206856253U". This patent mainly uses wool felt to directly contact the embossing roller to play a wiping role, so that impurities in the production process are adsorbed on the wool felt, and the surface of the embossing roller is always in a clean state, so that the ink can be better transferred to the film, thereby improving product quality and appearance. During the startup process, workers no longer need to wipe it by hand, which eliminates the production safety hazards brought about, and there is no need to choose to stop the machine for processing, which eliminates the secondary startup loss caused by restarting the machine. However, when the gravure direct embossing printing device is used, the ink in the groove needs to be added after a period of use. In this way, during the adding process, the ink may drip on other positions of the printing device, so it is necessary to wipe the dripping ink, which increases the workload of wiping and reduces the processing efficiency of the gravure direct embossing printing device.
