[0002] The printing cylinder is the core component of the printing machinery. Its surface finish and geometric accuracy will have a significant impact on the quality of the printed product. Especially when printing exquisite printed products, the slightest error will reduce the overall effect of the printed product and make both sides of the double-sided printed products appear blurry or distorted. Since the acid ink, alcohol, water and other chemical raw materials used in the printing process will corrode both sides of the printing cylinder, it often causes partial collapse and spots of the ink roller and plate cylinder, so the printing cylinder needs to be cleaned in time to extend the service life of the printing cylinder.

[0003] The existing printing roller cleaning is generally based on manual cleaning, which results in a large consumption of manpower, and the objects cleaned from the roller will fall on the operating table, requiring secondary cleaning, resulting in low cleaning efficiency and affecting actual production. Therefore, technical personnel in this field provide a printing roller cleaning device to solve the problems raised in the above background technology. Utility Model Content
