Description

Technical Field

[0001] The utility model relates to the technical field of fluorosilicone rubber compound meshing processing equipment, in particular to a high-efficiency fluorosilicone rubber compound kneading device. Background Art

[0002] Fluorosilicone rubber is a high-grade rubber material with excellent properties such as high-temperature resistance, chemical corrosion resistance, fuel resistance, and aging resistance. It is commonly used to manufacture high-end seals in the fields of aviation, aerospace, chemical industry, and automobiles. The fluorosilicone rubber mixing kneading machine is one of the indispensable equipment for fluorosilicone rubber processing. The advantage of the kneading machine is that it can quickly and efficiently mix and knead fluorosilicone rubber and other materials to produce high-quality seals and other products. The fluorosilicone rubber mixing kneading machine usually consists of a chassis with a mixing chamber, kneading blades, a motor, a transmission system, a heating system, and other parts. Fluorosilicone rubber and other materials are placed in the mixing chamber of the chassis. Then, through the rotation of the kneading blades and the heating of the heating system, the materials are fully mixed and kneaded to achieve the ideal molding state. Finally, the mixture is molded through a mold to produce the required seals and other products. However, this type of fluorosilicone rubber kneading machine has the following problems: the fluorosilicone rubber has very low fluidity, making it difficult to mix effectively, which reduces the kneading efficiency of the fluorosilicone rubber. In addition, the fluorosilicone rubber kneading process is easily affected by the external ambient temperature, which has certain disadvantages. To address this issue, we propose a high-efficiency fluorosilicone rubber kneading device. Utility Model Content
