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

A scraping device for a roller machine comprises bases, two torsional springs, a rotating shaft, a scraping plate assembly and a scraping knife. The bases are of a U-shaped structure, the concave parts of the bases are oppositely arranged, and grooves are formed in the concave parts of the base. The rotating shaft is rotationally arranged in the grooves of the concave parts of the base. The two torsional springs are arranged on the rotating shaft in a sleeved manner and located in the concave parts of the bases. The torsion fulcrums of the torsion springs are fixed to the bases, one end portions of the torsion springs are fixed to the bases, and the other end portions of the torsion springs exert torsion on the scraping knife. The scraping plate assembly is arranged on the upper portion of the rotating shaft and comprises a scraping knife installation base, a connection plate and a scraping plate main frame. The scraping knife installation base is of a U-shaped structure, and the non-concave face of the scraping knife installation base is arranged on the connection plate. The lower portion of the connection plate is provided with the scraping plate main frame. The scraping knife is installed on the concave part of the scraping knife installation base. The angle between the scraping knife and the scraping plate main frame is 90 degrees. The scraping device has the beneficial effects that the scraping effective acting force is improved, abrasion is reduced, and the service life of the scraping knife is prolonged.

Description

technical field [0001] The invention relates to a cleaning device for sticky material on the roller surface of a double roller machine, in particular to a scraping device used on the double roller machine. Background technique [0002] Nowadays, the crushing operation of the 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 surface of the roller. More materials accumulate on the roller surface in a short period of time, which greatly affects the crushing efficiency and crushing quality. The common practice in the crushing roller industry is to use a plate scraper to scrape off the powder sticking to the roller surface. The way of contact with the roller surface is to apply elastic force to the plate scraper by the compression spring, and the blade is in contact with the roller surface, and the w...
