Problems solved by technology

When the blade of the plate scraper does not point to the center of the circle, and the extension line deviates far from the axis of the roller, a large wear bevel will be formed at the blade during gradual use. After the wear bevel appears, the scraping ability will drop rapidly, and the replacement cycle of the scraper will be shorter. short

Abstract

The invention relates to a material scraping device which comprises a base, torsional springs, rotating shafts, material scraping plate assemblies, a scraping cutter and an adjusting plate. The base is of a concave structure, concave parts of the base are oppositely arranged, and grooves are formed in the concave parts of the base; the rotating shafts are rotationally arranged in the grooves of the concave parts of the base; the two torsional springs are arranged on the rotating shafts in a sleeving manner and are located at the concave parts of the base; torsional spring twisting force fulcrums are fixed to the base, one end of each torsional spring is fixed to the base, and the other end of each torsional spring applies twisting force to the scraping cutter; the material scraping plate assemblies are arranged at the upper positions of the rotating shafts; the adjusting plate is arranged to be in an L shape, and the base is arranged on the adjusting plate in a sliding manner; and a limiting hole is formed in the contact face of the adjusting plate and the bottom face of the base and is used for fixing the material scraping device to a double-roller machine and adjusting the distance between the material scraping device and the double-roller machine. The material scraping device has the beneficial effects that the effective material scraping action force is improved, abrasion is reduced, and the service life of the scraping cutter is prolonged.

Description

technical field [0001] The invention relates to a cleaning device for sticky material on the roller surface of a roller machine, in particular to a scraping device. Background technique [0002] Nowadays, the crushing operation of the double-roller machine is to drive the material to be squeezed between the two rollers through the rotation of the two rollers so that the material is crushed. During the crushing operation, the material to be broken is easy to stick to the roller surface. In a short period of time, more materials accumulate on the roller surface, which greatly affects the crushing efficiency and crushing quality. The common practice in the crushing pair-roller industry is to use a plate scraper to scrape off the powder stuck on the roller surface. The contact between the plate scraper and the roller surface is to apply elastic force to the plate scraper by the compression spring, the blade contacts the roller surface, and the wear of the blade during operation ...
