Problems solved by technology

However, if it is directly applied to cloth-covered V-belts, there are still many defects. The composition of the fiber film is unreasonable. It is directly applied to cloth-covered V-belts. Since the strength layer is made of polyester hard cord, the material is relatively hard. In the process, the product will be dented. In addition, although the fiber film is added with short polyester fibers, because the fiber film is formed by calendering during processing, the short polyester fibers in the fiber film are longitudinally arranged. Direct use will make the arrangement direction of the short polyester fiber consistent with the direction of the polyester hard cord wound longitudinally in the V-belt, so that it will not play a supporting role, and it will also make the product prone to dents, serious lateral deformation, and reduce product quality. service life

Abstract

The invention relates to a wrapping cloth V belt and a manufacture method of the wrapping cloth V belt and belongs to the technical field of mechanical transmission devices and materials. The wrapping cloth V belt comprises a core layer and a wrapping cloth layer covered on the outer surface of the core layer. The core layer sequentially comprises a base glue layer made of fiber glue pieces, a viscose layer, a polyester hard line rope and a buffering glue layer from bottom to top. The fiber glue pieces comprise natural rubber, butadiene styrene rubber, chloroprene rubber, reclaimed rubber, anti-aging agents, stearic acid, magnesium oxide, carbon black, softening agents, short fibers, zinc oxide, padding, and accelerating agents. The fiber glue pieces manufactured by mixed refining undergo horizontal cutting and splicing, and therefore short fibers in the fiber glue pieces are horizontally arranged. The finished wrapping cloth V belt is obtained through treatment of forming, cutting, cloth wrapping, vulcanization and demolding. Components in the rubber pieces are reasonable in ratio, and the wrapping cloth V belt has the advantages of being high in intensity, not prone to horizontal deformation, and long in service life. The manufacture method of the wrapping cloth V belt is simple in technology and easy to operate.

Description

technical field [0001] The invention relates to a cloth-wrapped V-belt and a preparation method thereof, belonging to the technical field of mechanical transmission equipment and materials. Background technique [0002] Wrapped V-belt is a kind of conveyor belt widely used in various machinery. It is mainly composed of industrial canvas, polyester soft cord and primer layer. The primer layer is mainly composed of natural rubber, styrene-butadiene rubber, reclaimed rubber and Compounding agent (zinc oxide, stearic acid, anti-aging agent, carbon black, softener, etc.). However, the existing cloth-wrapped V-belts generally have the problems that the product is easy to sag, resulting in large deformation, poor fatigue resistance and flexibility, prone to failure, and short service life. The existing cloth-wrapped V-belts also have polyester cords wound longitudinally inside the V-belt (equivalent to the length direction of the cloth-wrapped V-belt) to provide the longitudinal t...
