Scraping device capable of adjusting stations

Abstract

The invention discloses a scraping device capable of adjusting stations. The scraping device comprises bases, two torsional springs, a rotation shaft, a scraping plate assembly, a scraper blade and adjusting plates; each base is of a concave structure, the concave portions of the bases are oppositely arranged, and grooves are formed in the concave portions of the bases; sensing devices are arranged on the bases and used for detecting the torsional force of the torsional springs; the rotation shaft is rotatably arranged in the grooves formed in the concave portions of the bases; the two torsional springs are arranged on the rotation shaft in a sleeving mode separately and located on the concave portions of the bases; the scraping plate assembly is arranged on the upper portion of the rotation shaft; the scraping plate assembly comprises a scraper blade installing base, a connecting plate and a scraping plate main frame; the scraper blade is installed on the concave portion of the scraper blade installing base, and a 90-degree included angle is formed between the scraper blade and the scraping plate; the bases are slidably arranged on the adjusting plates; and the faces, making contact with the bottom faces of the bases, of the adjusting plates are provided with limiting holes, and the limiting holes are used for fixing the scraping device to a roll machine and adjusting the distance between the scraping device and the roll machine. The scraping device capable of adjusting the stations has the advantages that the scraping effective acting force is improved, wear is reduced, and the scraper blade life 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 with an adjustable station. 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 w...

AI Technical Summary

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
