Description

Technical Field

[0001] The utility model relates to the technical field of angle measurement, in particular to a device for measuring the angle of a scraper. Background Art

[0002] The scraper is one of the important components of printing equipment. The main function of the scraper is to control the thickness and uniformity of the ink, so that the surface of the printed product is smooth and colorful. During the printing process, the printing scraper needs to withstand greater pressure and friction, so it needs to be replaced and maintained regularly. At the same time, the installation angle and pressure adjustment of the printing scraper also need to be appropriately adjusted according to actual conditions to ensure the optimization of the printing effect. A suitable installation angle can reduce the wear of the scraper, and the lowest possible scraper pressure can also be used to achieve the purpose of scraping off the ink. When installing the scraper on existing printing equipment, most of the workers install it based on their experience, and the installation angle of the scraper cannot be accurately controlled, which shortens the service life of the scraper. Therefore, we have made improvements to this and proposed a device for measuring the scraper angle. Utility Model Content
