Description

Technical Field

[0001] The utility model relates to the technical field of scraper installation, in particular to a scraper clamp for a gravure printing machine. Background Art

[0002] The working principle of the gravure printing machine is that the grooves on the gravure cylinder carry ink to contact the printing substrate such as paper under the pressure of the embossing roller, and the text or pattern on the gravure cylinder is printed on the substrate. During the production process of the gravure printing machine, in order to prevent the ink other than the cells from being transferred to the paper, the scraper needs to scrape the plate surface continuously during the rotation of the printing plate to scrape off the ink other than the cells on the plate to ensure normal production.

[0003] However, the existing ink scraper clamp is usually pressed by a thin plate. Since the steel of the clamp is not strong, the clamping force of the clamp is insufficient, so that the ink scraper often becomes loose during uninterrupted work, which greatly reduces the ink scraping effect and makes the ink not scraped clean, thus affecting the quality of the produced products. In addition, the entire thin plate needs to be removed before it can be replaced during disassembly, and it needs to be repositioned, installed and debugged during installation. The disassembly and assembly process is extremely inconvenient. At the same time, the existing clamp does not have the ink collection function, so the scraped ink falls onto the entire machine tool, seriously affecting the surrounding production environment.
