Description

Technical Field

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

[0002] Raw rubber is composed of linear macromolecules or linear macromolecules with branches. Under the action of external forces, its mechanical properties are low and its scope of use is extremely limited. Therefore, raw rubber needs to undergo a series of processing to be made into useful rubber products. Among them, rubber plasticization and mixing are two important rubber processing processes. At present, the most widely used and effective plasticization method for raw rubber plasticization is mechanical plasticization. Its principle is to use the high shear force of the machine to destroy and degrade the rubber macromolecule chain to obtain plasticity. Mixing is another rubber mixing process based on plasticization, which can be achieved through a mixer. By adding the corresponding compounding agent to the mixer and fully mixing and reacting with the plastic, the physical and chemical properties of the plastic are changed to meet the standards required by the industry.

When adding auxiliary materials, the auxiliary materials are easy to block the feed pipe, and sometimes manual unblocking is required. In addition, it is not easy to control the amount of added auxiliary materials, which can easily lead to unsatisfactory rubber mixing effects and reduce production efficiency. Utility Model Content
