Technical Field
[0001] The utility model belongs to the technical field of rubber tire production, in particular to a stirring mechanism used for an auxiliary machine of tire rubber mixing. Background Art
[0002] With the continuous development of the tire industry, tire rubber mixing auxiliary equipment plays a vital role in the rubber processing process. In the tire rubber mixing process, the performance of the mixing mechanism directly affects the quality of the rubber and production efficiency.
[0003] Currently, in the field of tire rubber mixing auxiliary equipment, existing stirring mechanisms primarily utilize single-shaft or simple multi-shaft stirring mechanisms. In practice, these stirring mechanisms typically utilize stirring blades to stir and mix the rubber. However, as demands for rubber quality continue to rise, existing technologies have gradually exposed several issues.
[0004] On the one hand, in order to improve the stirring effect, the existing technology often requires increasing the area of the stirring blades. When the area of the stirring blades increases, the resistance encountered by the stirring shaft during rotation will also increase accordingly. This not only places higher demands on the power of the stirring motor, but also increases the energy consumption and operating costs of the equipment. At the same time, the greater resistance will also affect the strength and stability of the stirring shaft, which can easily cause the stirring shaft to deform or even be damaged, reducing the service life of the equipment; on the other hand, the stirring area is limited by the blade area. Even if the area of the stirring blades is increased, the stirring efficiency is still limited due to the low stirring speed and the single stirring direction. Therefore, in the mixing chamber, the traditional multi-blade single-rod stirring shaft has the problems of large stirring resistance and limited stirring efficiency. Utility Model Content
[0005] In view of this, the utility model provides a stirring mechanism for an auxiliary machine of tire rubber mixing, which can solve the problem that the traditional stirring shaft is in the mixing chamber, the traditional single-rod stirring shaft with stirring blades occupies a large area, and has high resistance to stirring rubber.
[0006] The utility model is achieved in this way:

Rotating grooves adapted to the rotation of the shaft disc are provided on both sides of the inner wall of the mixing chamber to ensure the stability of the shaft disc during rotation and reduce shaking and friction. The first stirring motor and the second stirring motor provide power to the first stirring shaft and the second stirring shaft respectively, enabling them to rotate at high speed for mixing. The motors are mounted on the outer walls of the mixing chamber on both sides through a fixed base plate, and the bolted connection ensures that the motors are firmly installed and will not loosen during operation, thereby ensuring the stability of mixing.

[0036] Example 2:
[0037] like Figure 2 As shown, it is a second embodiment of a stirring mechanism for an auxiliary machine of tire rubber mixing provided by the utility model. In this embodiment, it includes a mixing chamber 10, wherein a first stirring shaft 11 and a second stirring shaft 12 are movably provided on both sides of the inner wall of the mixing chamber 10, and the first stirring shaft 11 and the second stirring shaft 12 rotate in opposite directions alternately.

[0048] The first stirring motor and the second stirring motor are both forward and reverse motors, and the rotation direction and speed can be adjusted. Therefore, the first shaft disc and the second shaft disc on both sides can rotate at the same speed in opposite directions or staggered. They can also rotate at different speeds in the same direction, usually set to rotate slower on the outside and faster on the inside.
[0049] Multiple curved, convex stirring ridges on the surfaces of the first and second stirring shafts rotate to stir the tire rubber within the mixing chamber. Due to the different positions and dimensions of the two stirring shafts, they cover different mixing areas, ensuring more thorough and even mixing of the rubber within the mixing chamber. The first and second shaft discs rotate stably within rotating grooves on either side of the mixing chamber's inner wall, ensuring smooth mixing. The entire device achieves efficient mixing of tire rubber through the synergistic effect of its components.
