Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber raw material pre-processing device. Background Art

[0002] Synthetic rubber, also known as synthetic elastomer, is a highly elastic polymer made artificially and is one of the three major synthetic materials. Synthetic rubber is a key material in tire manufacturing, providing excellent elasticity and wear resistance.

[0003] Patent document CN221369033U discloses an angle-adjustable food material elevator, comprising a support base, two sets of motor housings, an adjustment assembly, and a conveying assembly, wherein the two sets of motor housings are symmetrically mounted on the top of the support base by bolts. The utility model is provided with an adjustment assembly. When the angle of the conveyor belt needs to be adjusted, the height of one end of the connecting plate can be adjusted by using an electric telescopic rod. The height adjustment of the connecting plate can adjust the inclination angle of the conveyor belt, making it easier for the conveyor belt to lift food materials to different heights. During the adjustment process, the other end of the connecting plate and the fixed block at the bottom end of the electric telescopic rod rotate with the corresponding transmission shaft respectively, and the drive motor drives the transmission screw to rotate. The rotation of the transmission screw drives the screw nut to move, and the movement of the screw nut drives the stabilizing rod to move, thereby adjusting the inclination angle of the stabilizing rod, ensuring the stability of the connecting plate and the conveyor belt, and achieving stable adjustment of the conveyor belt angle.

[0004] In the above scheme, the elevator can lift the raw materials to different heights, but the rubber raw materials do not need to be lifted to different heights. They only need to be poured from the rubber mixing device into the hopper, and then the hopper is lifted to the set height and poured into the rubber plasticizing equipment. Since the rubber raw materials have a certain weight, the elevator requires strong stability and good driving force, and at the same time needs to meet the function of dumping the hopper. The elevator cannot dump the raw materials, but can only lift the raw materials to the top of the elevator and then drop them, which are easy to scatter to the outside. Therefore, it is necessary to provide a rubber raw material pretreatment device to solve the shortcomings of the existing technology. Utility Model Content
