Technical Field

[0001] The utility model relates to the technical field of roller cleaning mechanisms, in particular to a cleaning mechanism for a printing roller. Background Art

[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. After long-term use, the printing press roller needs to be cleaned by a printing roller cleaning mechanism.

[0003] Existing cleaning mechanisms for printing rollers clean the printing rollers by means of a cleaning brush on a scraper, but most of the scrapers are fixed structures, making it inconvenient to clean printing rollers of different sizes, and the cleaning brush is not convenient to disassemble and clean. Therefore, a cleaning mechanism for printing rollers is needed. Utility Model Content
