Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a quick-change printing knife for printing machines. Background technique [0002] At present, high-end printing scrapers have high requirements on the edge of the blade, not only must have elasticity, but also rigidity and wear resistance, but this kind of knife is difficult to produce in China, generally imported from Germany, Sweden and Japan, so the entire high-end printing scraper The market is basically occupied by foreign countries, so now there is an urgent need for a printing scraper with a simple manufacturing method and strong blade quality. If the accumulated slurry is not collected in time, there will be no slurry in the printing area, printing quality problems caused by the drying of the accumulated slurry, and Part of the slurry is wasted, and there are printers with return wing scrapers on the market that can be installed, but often the size of the retur...
