[0002] Ink dust failure refers to a printing failure in which certain substances adhere to the printing plate or rubber blanket during the printing process. The place where the foreign matter adheres is higher, the printing pressure is high, and more ink is printed, while the surrounding areas are squeezed and deformed and cannot be printed with ink, resulting in a printing failure in which the center ink dot is dark in color and the surrounding areas have white edges. This usually occurs when printing solid fields.

[0003] After searching, it was found in the Chinese Utility Model Patent Publication No. CN203697699U that when ink residues appear on the substrate during operation, the operator finds the ruler portion corresponding to the automatic paper collection position, operates the push rod device to make the scraper on the push rod terminal contact the printing roller to scrape off the ink residues, but the scraped ink residues may float in the air around the equipment, causing the scraped ink residues to become dust impurities that still stick to the equipment. At the same time, the scraper cannot always be attached to the surface of the printing roller, and the cleaning mechanism needs to be adjusted all the time, resulting in reduced printing efficiency and affecting product production efficiency. Therefore, a device that can continuously clean the equipment and collect impurities such as ink residues is needed. Utility Model Content
