Description

Technical Field

[0001] The utility model relates to the technical field of embossing scrapers, in particular to an adjustable scraper. Background Art

[0002] In the field of gravure printing, precise control of ink transfer is one of the key factors to ensure printing quality. The scraper device plays a vital role in this process. It is responsible for effectively scraping off excess ink on the printing plate to ensure the clarity and uniformity of the printed pattern. Traditional gravure printing machines generally use a fixed scraper design, which has exposed several shortcomings in practical applications.

[0003] First, the installation of scrapers in the prior art often relies on manual trial and error adjustments to achieve the ideal scraping position and pressure. When the initial installation position of the scraper is improper or fine-tuning is required, the existing fixed installation method usually requires the scraper to be completely disassembled and then repositioned and installed. This series of operations is not only cumbersome and complicated, but may also cause wear of the scraper or printing equipment due to repeated disassembly and assembly, affecting long-term stability and service life. Secondly, faced with the need to replace printing rollers of different diameters, traditional scraper systems lack the ability to quickly adapt to different roller sizes. After each roller is replaced, the distance between the scraper and the roller surface needs to be recalculated and adjusted according to the diameter of the new roller. This process also requires the scraper to be disassembled and assembled again, which seriously affects production flexibility and response speed, and is not conducive to efficient printing job switching. No effective solution has been proposed to the problems in the relevant technology. Utility Model Content
