Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber processing, and more specifically, to a crushing device for silicone rubber raw materials. Background Art

[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and usually two organic groups are connected to the silicon atoms. Ordinary silicone rubber is mainly composed of siloxane chain segments containing methyl and a small amount of vinyl. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano can improve the temperature resistance and oil resistance of silicone rubber. During the production process of silicone rubber treatment agents, the required raw materials need to be crushed.

[0003] At present, during the production and processing of silicone rubber raw materials, the raw materials need to be crushed after collection for subsequent melting, extrusion and granulation. Since the silicone rubber raw materials are soft materials, during the crushing process, when they are subjected to shear pressure, they can pass through the gaps between the crushing knives through their own deformation. Therefore, when traditional crushing equipment crushes silicone rubber raw materials, it is usually not easy to ensure the full crushing of the raw materials, and there will still be some parts that are not fully crushed in the raw materials, which affects the production and processing of subsequent steps. In view of this, we propose a crushing device for silicone rubber raw materials. Content of the Utility Model

[0010] In the present utility model, by designing a gear and a rack, the first pushing structure can push the second pushing structure to deflect, so that the crushing assembly deflects synchronously with the second pushing structure. During the deflection process, it will drive the connecting plate one, the U-shaped plate one and the U-shaped plate two to move, so that the gear meshes with the rack and rolls, and the position of the rack is automatically adjusted by the longitudinal elastic mechanism to adapt to the deflection trajectory. During the rolling process of the gear, since the gear is fixedly connected to the U-shaped plate one, it can drive the connecting plate one, the U-shaped plate two and the fixed block to roll synchronously, and then make the whole crushing assembly rotate, realizing the flipping of the raw material during the process of crushing the silicone rubber raw material, so as to realize the repeated crushing of the raw material.

A pressing plate is slidably arranged on the outer edge surface of the positioning rod, and the top end of the positioning rod extends through the pressing plate and is structurally connected with a limiting block. A spring sleeved on the outer part of the positioning rod is arranged between the bottom plate and the pressing plate.

[0012] Preferably, the crushing structure includes a motor detachably installed on one side of the fixed block. The shaft of the motor rotatably passes through the fixed block and is connected with a crushing knife rotatably arranged in the crushing cylinder.

[0013] Preferably, the bracket structure includes a connecting plate two fixedly connected to the triangular bracket at both ends. One side of the connecting plate two is structurally connected with an L-shaped bracket. A connecting frame is structurally connected between the triangular brackets.
