Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and more specifically, to a scraper for printing rollers of a label printing press. Background Technology

[0002] Labels are tools used to identify the target and classification or content of products, making it easier for oneself and others to find and locate the target. In the printing industry, labels mostly refer to printed materials used to identify relevant information about one's products, and the printing presses used to print these labels are called label printing presses. In today's society, when label printing presses are printing labels, if the ink gets damp or is used for too long, the ink will accumulate and harden on the printing rollers, affecting the printing quality of the labels.

[0003] A scraper for a label printing machine's printing roller, disclosed in publication number CN 217197437U, involves connecting and supporting the printing roller via a fixed mechanism, causing a rotary motor to drive the printing roller to rotate, and then an electric telescopic rod to move the mounting base. During this movement, the scraper blade cleans any position on the printing roller. However, this scraper requires the printing roller to rotate before the scraper blade can move and scrape the ink, making it difficult to clean the entire printing roller and causing inconvenience. Furthermore, it hinders the collection of scraped ink, resulting in ink fragments scattering randomly.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
