Rubber mixing machine with self-cleaning function

Abstract

The invention belongs to preparation or pre-treatment of formed materials and particularly discloses a rubber mixing machine with a self-cleaning function. The rubber mixing machine comprises a rubber mixing machine body and further comprises a first screw and a second screw which are mutually engaged, wherein the first screw and the second screw are rotationally disposed on the rubber mixing machine body; the first screw and the second screw are both conical screws; the depth of screw grooves of the first screw and the second screw is gradually changed in the length direction of the screws; the ratio of the depths of the screw grooves of the first screw and the second screw is equal to the ratio of the diameters of the first screw and the second screw. Compared with traditional rubber mixing machines, traditional rotary rollers are replaced with the first screw and the second screw which are mutually engaged; as the screws are mutually engaged, the effect of mutual scraping between the first screw and the second screw is achieved, the certain self-cleaning purpose can be achieved without extra scraping equipment, and therefore the rate of excellent products is increased.

Description

technical field [0001] The invention belongs to the preparation or pretreatment of molding materials, in particular to a rubber mixing machine with self-cleaning function. Background technique [0002] Mastication is a process of rubber processing, which refers to the use of mechanical or chemical methods to reduce the molecular weight and viscosity of raw rubber to improve its plasticity and obtain appropriate fluidity to meet the needs of further processing of mixing and molding. In the process of plasticizing, rubber mixers are often used. The existing rubber mixing machine mainly includes two rotating rollers. The rotating rollers are installed on the frame. The raw rubber is between the two rotating rollers of the rubber mixing machine. 1.27) The shear force generated breaks the rubber macromolecules, thereby achieving the purpose of plasticization. However, when mixing rubber, more residues are often produced and stay on the rubber mixing machine. The residue on the ...

AI Technical Summary

Problems solved by technology

However, when mixing rubber, more residues are often produced and stay on the rubber mixing machine. The residues on the rubber mixing machine are easy to be mixed into the subsequent manufacturing of new products, affecting the use of the next process and affecting the good rate of finished products.
