Abstract

The invention relates to the printing industry, in particular to an ink scraper. The ink scraper comprises a scraper body (1), wherein the surface of the scraper body (1) is coated with a tungsten carbide metal layer (2) formed by spraying semi-molten tungsten carbide particles with a speed of 800 m / s. The ink scraper has the following effects: as the scraper body is coated with the tungsten carbide metal layer formed by spraying the semi-molten tungsten carbide particles with the speed of 800 m / s, the service life of the scraper is largely prolonged, the ink scraping effect is improved, the corrosion resistance is excellent, drag wires are effectively reduced, and the waste is prominently reduced. The reduction of scraper replacing times means the shortening of stop time; and the stripping and renewed carving conditions of a printing drum are reduced. The scraper is excellent in effect when using UV ink.

Description

technical field [0001] This application relates to the printing industry, in particular to an ink scraper. Background technique [0002] Under normal use conditions of the printing machine, the wear resistance of the conventional scraper is poor, and the edge of the cutting edge can only touch the plate cylinder, and the scraper gradually wears out! The cross-sectional area of ​​the contact part is also constantly increasing, which is very unfavorable to ink scraping and will cause changes in the tone value of the image after printing. In this case, the life of the scraper is very short. In order to ensure the consistency of the printed matter, the scraper must be adjusted continuously, which affects the printing quality of the product, which is very troublesome and cumbersome. Contents of the invention [0003] The purpose of this application is to provide an embodiment of an ink scraper, hoping to solve the problem that the existing ink scraper is easy to wear and needs...
