[0002] Silicone rubber is a kind of high polymer whose main chain is alternately composed of silicon and oxygen atoms, and silicon atoms are usually connected with two organic groups. It has excellent high and low temperature resistance, good electrical insulation, excellent weather resistance and physiological inertia, and is widely used in many fields such as aerospace, electronics, medical health, automobile industry, etc.

[0003] Silicone rubber needs to be kneaded in the production process, because its performance depends on the uniform mixing of raw rubber and various additives such as vulcanizing agent, reinforcing agent and filler. Through kneading, each component can be fully dispersed to form a uniform system in microcosm, so as to ensure that the silicone rubber products meet the expected requirements in terms of physical properties, chemical properties and processing properties. However, the existing silicone rubber kneader has the following problems: most of the existing silicone rubber kneaders adopt the way of hopper discharge, which has great safety hazards. Whether it is the structural strength of the silicone rubber kneader itself or the manual assistance of silicone rubber discharge, the hopper discharge is prone to cause safety accidents. In view of this, we propose a silicone rubber material kneading device. UTILITY MODEL CONTENTS
