Description

Technical Field

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

[0002] Mixing refers to the process of adding various compounding agents, such as fillers, reinforcing agents, accelerators, vulcanizers, antioxidants, anti-scorch agents, etc., to raw rubber or plastic rubber in order to improve the physical and mechanical properties of rubber products, improve the processing and molding technology, and reduce production costs. These compounding agents are solid, liquid and other materials. The various added compounding agents are evenly dispersed to ensure the consistency of the properties of the rubber. Therefore, the process of evenly dispersing various compounding agents into raw rubber or plasticized rubber on a rubber mixer is called mixing, and the rubber made by mixing is called mixed rubber. Mixing is the process of evenly mixing raw rubber or plastic rubber with various compounding agents through mechanical action, and its uniformity often determines the output quality of mixing. Therefore, it is very important to improve its uniformity during the mixing process.

The mixing device realizes the opposite rotation of the mixing furnace body and the auger through structural coordination, and the mixing is more uniform and the effect is better.

[0004] The applicant found that there are some shortcomings in use: the patent uses two first sprockets, a second sprocket and a chain for transmission. Since the two first sprockets have the same diameter, affected by the chain tension, the middle first sprocket is prone to slippage with the chain, resulting in reduced transmission efficiency and unstable operation, which affects the rotation speed of the two shafts and reduces the stirring effect.

[0005] Therefore, the utility model designs a rubber processing mixing device to solve the problems existing in the prior art. Utility Model Content
