Problems solved by technology

[0005] The rubber extrusion process is usually extruded in the extrusion mechanism. The existing extrusion mechanism usually includes an extrusion cylinder and an extrusion screw. The extrusion cylinder is provided with a cylindrical cavity, and the extrusion screw is located in the cylindrical cavity. However, during the extrusion process, especially when the operation of the rubber extrusion mechanism is frequently stopped and restarted, the amount of rubber just extruded from the extrusion cylinder is small, and the extrusion pressure is small, so it is usually extruded The rubber produced does not meet the requirements

Abstract

The invention discloses an extrusion device used for rubber processing. The extrusion device comprises an extrusion cylinder, a rotating shaft, an extrusion screw and a power source which drives the rotating shaft to rotate. The extrusion screw is connected with the rotating shaft, the extrusion cylinder is internally provided with an extrusion cavity, and the rotating shaft is positioned in the extrusion cavity. The extrusion cylinder is provided with a feed hopper which communicates with the extrusion cavity and a transition section which is provided with a transition cavity. The transitioncavity communicates with the discharging side of the extrusion cavity. a memory metal piece for opening and closing the transition cavity and a reset piece are arranged inside the transition cavity, and when the memory metal piece is stressed to open the transition cavity, the ultimate pressure is 120-150 Pa. One end of the reset piece is connected with the inner wall of the transition cavity andthe other end of the reset piece is connected with the memory metal piece. Under the condition that the extrusion device can be frequently stopped and restarted, the extrusion pressure of rubber justextruded from the extrusion cylinder is sufficient so that the extruded rubber meets the requirements.

Description

Technical field [0001] The invention belongs to the field of plastic molding or connection, and specifically relates to an extrusion device for rubber processing. Background technique [0002] Early rubber was made of rubber latex from rubber trees, rubber grass and other plants. After processing, it was made of elastic, insulating, impervious to water and air. Highly elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. [0003] The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily-use, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and ot...
