Self-cleaning device suitable for conveying belt for small metal part hardening and tempering

Abstract

The invention discloses a self-cleaning device suitable for a conveying belt for small metal part hardening and tempering. The self-cleaning device comprises a conveying device and cleaning device bodies arranged at the lower end of the conveying device; the conveying device comprises a pair of transmission shafts, a reversing shaft and the conveying belt, wherein the reversing shaft is arranged below the transmission shafts, and the conveying belt surrounds the transmission shafts and the reversing shaft; a pair of limiting shafts which are symmetrically arranged and located on the outer sideof the conveying belt are arranged on the two sides of the reversing shaft; each cleaning device body comprises a water spraying assembly, a water scraping plate and a material scraping assembly which are sequentially arranged in the conveying direction of a lower layer of the conveying belt; each water spraying assembly comprises a water tank, a liquid guide pipe and a spray head, wherein the spray head extends to the end surface of the conveying belt; and each material scraping assembly comprises a waste material box and a material scraping plate fixed to the upper end of the waste materialbox. The self-cleaning device has the advantages that the cleaning device bodies comprise the water spraying assemblies and are used for wetting impurities on the surface of the conveying belt, and therefore subsequent material scraping can be facilitated; the reversing shaft and the limiting shafts are arranged and are used for increasing the contact area between the conveying belt and the reversing shaft, and therefore the set range of the cleaning device bodies can be widened, and the cleaning effect can be improved.

Description

technical field [0001] The invention relates to a self-cleaning device for a conveyor belt, in particular to a self-cleaning device suitable for a conveyor belt for tempering small metal parts. Background technique [0002] Small metal parts are generally conveyed through the conveyor belt during heat treatment, and during the transmission process, the impurities adhered to the small metal parts will adhere to the conveyor belt again. After long-term work, the impurities will affect the processing accuracy of the product and affect The surface quality of the product requires a conveyor belt cleaning device, and the traditional cleaning device scrapes the material through the scraper, but the angle between the scraper and the belt needs to be controlled reasonably during the scraping process, and sometimes the surface of the conveyor belt needs to be controlled Humidity, so the present invention develops a self-cleaning device applicable to the conveyor belt for tempering of ...
