Description

Technical Field

[0001] The utility model relates to the technical field of rubber material production equipment, in particular to a rubber mixing mill with rapidly adjustable discharging size. Background Art

[0002] The mixing mill is mainly composed of rollers, a frame, a spacing device and a transmission device. The material is pulled into the gap between the two rollers rotating in opposite directions at different linear speeds under the action of friction. The material in the frame is subjected to strong shearing and extrusion through the gap between the rollers, which increases the temperature of the material and the plasticity, thereby achieving the purpose of rubber refining. It is used for operations such as plastic refining, mixing, sheeting and hot refining.

[0003] In order to optimize the process flow during the refining of some materials, it is necessary to directly shape the width size of the output material on the pressing roller. Therefore, it is necessary to set a pair of width plates above the pressing roller. In this way, after roller pressing, due to the limitation of the width plate, the pressed material can directly have the corresponding width size. However, the existing width plates need to be adjusted one by one, and the distance between the two plates must also be determined. The adjustment steps are relatively cumbersome and cannot achieve the corresponding accuracy well, which needs to be improved urgently. Utility Model Content
