Description
Technical Field
[0001] The utility model relates to the technical field of rubber roller mixing devices, in particular to a rubber roller processing mixing device with uniform mixing. Background Art
[0002] The processing of rubber rollers includes processes such as roller core sandblasting, bonding, rubber forming, cloth wrapping, wire winding, autoclave vulcanization and surface processing. For rubber rollers, the mixing of rubber compounds is the most critical link. There are more than 10 types of rubber compounds for rubber rollers, ranging from natural rubber, synthetic rubber to special materials. The rubber content is 25% to 85%, and the hardness is soil (0 to 90) degrees, covering a very large range. Therefore, how to make these rubber compounds mix evenly has become a major problem. The conventional method is to use an open mixing mill for mixing.
[0003] The existing open mixing mill generally includes two rollers rotating relatively to each other, which melt, mix and extrude the materials under high pressure. The materials are pulled in between the two rollers. Due to the friction and adhesion of the rollers, the materials are subjected to strong shearing and extrusion in the roller gap, which causes the materials to deform and increases the interface between the components, thereby achieving distributed mixing. However, since the raw materials mixed by the rubber roller contain multiple types and cannot be mixed during mixing, the raw materials are easily piled up during mixing, which will cause the problem of uneven mixing, affect the mixing effect, and cannot ensure the uniformity of the rubber roller quality.
[0004] Therefore, in order to solve the above-mentioned problem of uneven mixing, a rubber roller processing mixing device with uniform mixing can be designed. Utility Model Content
