Description

Raw material screening device for rubber production Technical Field The utility model relates to the technical field of rubber pad production, in particular to a raw material screening device for rubber production. Background Rubber products refer to activities of producing various rubber products from natural and synthetic rubber, and also include rubber products regenerated from waste rubber, the yield of synthetic rubber has greatly exceeded that of natural rubber, and the yield is the greatest of styrene-butadiene rubber. Rubber products are various, but the production process is basically the same, and the basic process of the rubber products taking general solid rubber raw rubber as raw materials comprises six basic procedures of plasticating, mixing, calendaring, extruding, forming and vulcanizing. In the existing rubber product raw material screening process, the conventional operation is to directly put raw materials on a fixedly installed screening net or screening plate for screening, and because the screening device adopts a static structural design, when the raw material input amount is too large, fine particles above a stacking layer are easily blocked by a physical barrier formed by large particles at the bottom, so that the fine particles cannot fully contact a screening interface, and the screening efficiency can be obviously reduced due to the shielding effect among the particle layers, so that the quality of a final finished product can be influenced. Accordingly, the present utility model provides a raw material screening apparatus for rubber production to solve the above-described problems.
