Description

Technical Field

[0001] The invention belongs to the technical field of rubber composition preparation, in particular to a rubber composition production device and a production method thereof. Background Art

[0002] The production of rubber compositions usually includes the following steps: raw material mixing, extrusion mixing, sheeting cooling, crushing, post-mixing, and molding. Mixing is the process of mixing raw rubber or plasticized raw rubber with compounding agents into mixed rubber using a rubber mixer. It is the most important production process in rubber processing. Mixing refers to improving the physical and mechanical properties of rubber products.

[0003] A Chinese patent with publication number CN218700314U discloses a rubber mixing device for tires, which relates to the field of rubber mixing technology and includes a mixing box. Two feed pipes are opened on the top of the mixing box, a discharge pipe is installed on the outer wall of the mixing box, a protective shell is installed on the top of the mixing box, and a motor is installed inside the protective shell. Raw rubber or plastic rubber and compounding agents enter the mixing box through the two feed pipes. The operator starts the motor through the control panel, and the spiral feeding rod rotates with the driving end of the motor to mix the raw rubber or plastic rubber with the compounding agent. By setting a stirring rod, the stirring and mixing effect is improved. By setting a scraper rod and a scraper bar, it is avoided that raw rubber or plastic rubber and compounding agents remain on the inner wall of the mixing box to waste raw materials and clean the inner wall of the mixing box to facilitate subsequent mixing. The problem that a lot of time is needed to clean the inner wall of the mixing drum after use of the existing rubber mixing device for tire processing, which delays subsequent mixing work.

[0004] In the above technology, local heating is performed by a heating rod. If the temperature is too high, the rubber will be sintered. If the temperature is too low, the water may not be fully volatilized, thereby trapping air in the rubber compound, causing bubbles to form in the material and reducing the quality of the rubber. If the rubber is only stirred by rotation, the mixing will be uneven, the surface will not be smooth when it comes out of the mold, and air may be trapped in the rubber compound, causing bubbles to form in the material.

[0005] To this end, the present invention provides a rubber composition production device and a production method thereof. Summary of the invention
