[0002] Before tire production, the various raw materials need to be stirred and mixed, then heated and melted to make rubber. In this process, most of the mixing is done by stirring, which cannot be completely stirred. In addition, the different sizes of raw material particles cause the mixing time to be too long and uneven, which partially affects the quality of the rubber products produced.

[0003] In order to solve the above problems, a Chinese patent (publication number: CN209869113U) discloses a raw material mixing device for rubber tire processing, including a processing box, a gear box, a screening box and a mixing drum.

[0004] Although the above technical solution crushes the raw materials in the processing box by setting a crushing roller, and then screens them using a screening box, so that the screened raw materials can be mixed more evenly, the inventor found in the process of implementing the above technical solution that the raw materials will gather at the bottom of the mixing drum under the action of gravity during mixing, which makes it difficult for this part of the raw materials to be quickly mixed with the raw materials in the middle and upper part of the mixing drum. In order not to affect the final mixing effect, the only option is to extend the mixing time, which reduces the mixing efficiency. Utility Model Content

[0025] The specific working process is: first, pour the raw materials into the crushing and screening box 7 from the feed port, then start the crushing component and the screening component, the raw materials are crushed by the crushing component and screened by the screening component, and then enter the mixing box 19 to be stirred by the stirring component. During the stirring process, the two sets of turning components continuously turn the raw materials at the bottom of the mixing box 19 upward so that they can be fully mixed with the raw materials in the middle and upper parts as soon as possible to improve the stirring efficiency. After the stirring is completed, open the discharge valve 20 at the discharge port to discharge the materials.

[0026] In this embodiment, by setting up two sets of turning components, the raw materials at the bottom of the mixing box 19 can be continuously turned upward so that they can be fully mixed with the raw materials in the middle and upper parts as quickly as possible, thereby improving the mixing efficiency, greatly reducing the time required for mixing, and optimizing the final mixing effect.

[0028] In this scheme, two rotating shafts 8, crushing rollers 9, a first motor 15, a first gear 14 and a second gear are arranged to cooperate with each other to realize the crushing of raw materials. When in use, the first motor 15 drives one of the rotating shafts 8 to rotate, and under the meshing action of the first gear 14 and the second gear, the other rotating shaft 8 rotates in the opposite direction, thereby driving the two crushing rollers 9 to rotate in the opposite direction to realize the crushing of the raw materials.
