Abstract

The invention relates to the technical field of rubber production, in particular to a waste rubber softening device for the rubber production. The waste rubber softening device comprises a feed pipe,a heating cavity and a flow-guiding pipe. Waste rubber is used as production raw materials, environment is protected, and energy is saved. The waste rubber is smashed by a smashing knife in the feed pipe, falls into the heating cavity, and is convenient to heat. An outer heating piece and an inner heating piece generate heat, and raw material particles falling into a grinding cavity fall on a grinding wheel; not only are heating and softening carried out, but also part of the raw material particles moves following the grinding wheel, and is in contact with the inner wall of a tank body to be heated and softened, so that uniform heating and softening of the rubber are realized. The softened rubber flows into the bottom of the heating cavity, is squeezed by the grinding wheel, and flows intothe flow-guiding pipe. The rotating shaft rotates to drive screw blades to rotate to stir the rubber so as to ensure the ductility. An insulating layer of the outer wall reduces heat loss to keep thetemperature.

Description

technical field [0001] The invention relates to the technical field of rubber production, in particular to a waste rubber softening device for rubber production. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. [0003] Existing rubber products are more commonly used in the form of injection molding, that is, the softened rubber is injected into the mold, and when the temperature is lowered, the rubber hardens to form a product. So the softening of the rubber works quite well. However, most of the softening devices in the prior art are heating tanks with small heating surfaces and uneven heating, which need to be improved. Contents of the invention [0004] (1) Solved technical problems [0005] The purpose of the present invention is to overco...
