Description

Technical Field

[0001] The utility model belongs to the field of rubber processing, and in particular relates to a rubber mixing mill for rubber processing. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. At present, the most commonly used general-purpose rubber in the market is a type of rubber that partially or completely replaces natural rubber, such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, etc. The mixing mill is a kind of plastic mixing equipment that was used relatively early in plastic product manufacturers. On the calender production line, the mixing mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniform molten material for the calender to calender and mold plastic products. Among them, the mixing mill is also needed for rubber during processing and mixing.

[0003] The patent application with publication number CN214773196U discloses a rubber mixing open mill, including: a mounting assembly, an open mill assembly and an adjustment assembly, wherein a box cover in the mounting assembly is hinged to the open mill box, the box cover is provided with a material inlet, and a material outlet is provided at the lower side of the open mill box. A first motor in the open mill assembly is fixed to the open mill box, one end of a first open mill roller is fixed to the first motor, and the other end is mounted to the open mill box, a mounting groove is provided on the open mill box, a moving block is provided in the mounting groove, a second open mill roller rotates on the moving block, and the second motor is connected to the end of the second open mill roller.

[0004] The above patent simply processes the rubber by setting up an open mixing box. In order to make the rubber mix more uniform, multiple processing and mixing are usually required. However, if the rubber needs to be processed multiple times, manual loading is generally required in the existing operation, which not only increases the workload of the workers, but also is prone to danger.

[0005] In summary, the utility model provides a rubber mixing mill for rubber processing to solve the above problems. Utility Model Content
