Technical Field

[0001] The present application relates to the technical field of impurity removal mechanisms, and in particular to an impurity removal mechanism of a scraper of a gravure printing machine. Background Art

[0002] Gravure printing is an important printing technology widely used in packaging, decoration, and other fields. It boasts high precision, a wide range of applications, rich colors, and high production efficiency. It enables printed products to have higher clarity and image quality, making it commonly used in large-scale production. Gravure printing presses are suitable for printing on a variety of substrates, including paper, plastic, and metal, and are currently widely used in industries such as packaging, labels, and cards. Gravure printing presses operate at high speeds and cannot be frequently stopped once in operation.

[0003] When the ink scraper removes ink from the gravure cylinder, impurities in the ink adhere to the scraper, affecting the scraping effect of the scraper. Therefore, the impurities attached to the scraper need to be scraped off regularly. The current method of dealing with this problem is to manually move a bamboo stick back and forth along the length of the scraper to scrape off the impurities attached to the scraper. During the manual scraping process, the bamboo stick may touch the paper, affecting production and needs to be improved. Utility Model Content

[0039] Combine Figure 3 and Figure 4As shown, the outer surface of the guide block 31 is rotatably connected to a plurality of balls 311, and the balls 311 abut against the inner wall of the guide groove 32. The tool holder 1 is detachably connected to a movable member 4 for driving the slide 2 to slide. The movable member 4 is a push rod 41. The push rod 41 is cylindrical. Two cross bars 42 are arranged on the outer circumference of the push rod 41 relative to each other. The push rod 41 and the cross bar 42 are integrally formed. One side of the slide 2 is provided with a first mounting groove 21 for the push rod 41 to be snapped in, a second mounting groove 22 for the cross bar 42 to be snapped in, and a rotation groove 23 for the cross bar 42 to be snapped in.
