Description

Technical Field

[0001] The utility model belongs to the technical field of open mixing mills, in particular to a rubber material open mixing mill used for preparing rubber bearings. Background Art

[0002] The open mixing mill is a kind of plastic mixing equipment that was used relatively early in plastic product manufacturers. On the calender production line, the open mixing mill is located before the calender and after the mixer. Its function is to mix and plasticize the evenly mixed raw materials, and provide a relatively evenly mixed and plasticized molten material for the calender to calender and mold plastic products. When producing cable materials, the open mixing mill can directly refine and plasticize the powdered materials mixed according to the formula into molten materials, and then press them into sheet strips, which are then cut into granules by the pelletizer. On the floor leather production line, it can directly provide cloth-based leather with an evenly mixed and plasticized base coating. Recycled waste plastic films (sheets) can also be re-refined and plasticized on the open mixing mill;

[0003] According to the announcement, an open mill for preparing high-heat-resistant composite rubber materials (announcement number: CN216578691 U) includes a workbench, a first roller is provided on the top of the workbench, a second roller is provided on one side of the first roller, the second roller bracket is larger than the diameter of the first roller, a layer strip is arranged around the surface of the second roller, a second support plate is provided on one side of the second roller, a protective frame is arranged on the outer side of the first roller, and the second support plate and the protective frame are fixedly arranged on the surface of the workbench. The utility model is provided with a second roller, a layer strip and a second support plate, and a plurality of layer strips are arranged around the surface of the second roller. When plastic processing is performed, the second motor drives the second roller and the layer strips on its surface to rotate, and the layer strip replaces the material passing through the gap between the second roller and the first roller for plasticizing. The repeated plasticizing of the plurality of layer strips can be performed multiple times within one rotation of the second roller, which greatly improves the overall plasticizing efficiency and saves energy and cost. However, the above-mentioned second roller bracket is larger than the diameter of the first roller, and the layer strips are arranged around the surface of the second roller, so it is difficult to achieve the stirring effect, which needs to be improved.
