Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a continuous mixer. Background Art

[0002] A mixer refers to an intermittently operated device used in the plastic processing industry to mix resins and various additives and melt and plasticize them to obtain evenly dispersed materials. Its working principle is that the material is added to the mixing chamber through the feeding door, and then the pressure pin is pressed down. The material is compacted under pressure and heated by steam passing through the jacket and the rotor cavity. It is also subjected to shearing, stirring, and extrusion between the rotor and the mixing chamber wall, as well as kneading and tearing between the two rotors, and quickly achieves mixing and plasticization. After mixing is completed, the discharge door is opened to discharge the block material.

[0003] During the operation of the mixer, raw rubber and compounding agents need to be added and mixed for stirring and mixing. For example, a utility model patent with application number CN202023108639.1 discloses a continuous mixer that is easy to load, including a base, on which a mixer is fixedly arranged, and the mixer is provided with a feed end and a discharge end, and also includes a support frame, which is arranged on one side of the mixer, and a feeder is arranged on the support frame, and the feeder includes a feeding roller, a conveyor belt and a feeding motor, and a limiting component is arranged on the support frame.

[0004] Although the above device can realize indirect feeding, workers do not need to manually feed the materials throughout the process, thus reducing the labor burden of workers; however, it is impossible to screen the raw rubber during the feeding process. Raw rubber of different sizes will not only lead to a longer mixing time during the mixing process, but also affect the quality of the final product.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content
