Description
Technical Field

Background
The tyre is a ring-shaped elastomer which is assembled on a rim or a wheel axle and is used as a connecting body between a vehicle and a road for running and sliding of the vehicle or an airplane. As one of the main components of an automobile, the production of a tire from a raw material to a finished product is roughly divided into 6 steps of kneading, preparing materials, molding, vulcanizing, inspecting and packaging, and cycle testing. Wherein, as the first step of tyre manufacture, the mixing is mainly the formula synthesis processing aiming at the tyre rubber compound, and the mixing quality directly influences various performances of the subsequent tyre finished products.
The raw materials of tires generally comprise four general classes: rubber, chemical additives, fiber materials and steel wires, and the process of extruding and mixing the raw materials such as rubber, ingredients, additives and the like together to obtain a rubber compound is generally called banburying in the tire industry, wherein the banburying provides a preparation material for the subsequent process of tire manufacturing, namely, the manufacturing of different parts of the tire is completed in other stations by other raw materials after different rubber formulas are subjected to the banburying process.
It is not difficult to see that the mixed banburying occupies an important position in the whole manufacturing work of the tire, and various performance parameters of the banburying rubber material can directly influence the wear resistance, the grip force and the heat dissipation capacity of the tire.
In the existing tire production, the compound banburying of rubber raw materials is realized by an internal mixer, which is a machine provided with a pair of rotors with specific shapes and relatively rotating and used for carrying out plasticating and mixing on polymer materials in a clearance way under the closed state with adjustable temperature and pressure, however, due to the structural defects of the existing internal mixer, the following defects are gradually exposed in the use process:
1. insufficient mixing of the raw materials leads to uneven composition of the composite sizing material obtained by compaction. Specifically, when raw materials are added in the conventional internal mixer, the raw materials are generally mixed in the internal mixing process in a mode of adding rubber, ingredients and additives in batches, and the mode has high treatment efficiency, but has poor material mixing effect, so that the problem of material accumulation or loss in different pressing areas is easy to occur, and the quality of the obtained rubber compound is poor.
2. The adaptability and the regulation of the mixed banburying are poor, and the mixed banburying is only applicable to the production of special type of compound sizing materials. Specifically, the internal mixing and pressing process is realized through a pair of autorotation pressing rollers, and in the existing internal mixing equipment, the pressing interval between the two pressing rollers is fixed and cannot be adjusted, so that the internal mixer can only be used for pressing and processing specific rubber materials, and the thickness of the rubber materials obtained by pressing is also fixed and cannot be suitable for producing tires of different types and specifications.
3. When the distance between the press rolls is adjusted, the existing transmission relation can be destroyed due to the change of the position of the press rolls, and the transmission parts such as gears and the like are required to be replaced, so that the operation is complex and the time consumption is long.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
