Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to an open mixing mill. Background Art

[0002] An open rubber mixer has two horizontally arranged rollers. It is a machine that mixes rubber (plastic) between the two rollers. It is referred to as an open mixer. It 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 material temperature and plasticity, thereby achieving the purpose of mixing rubber. It is used for plasticating, mixing, tableting and hot refining.

[0003] For example, a utility model patent with application number CN202020704093.7 discloses an open mixing mill, including: a motor, a coupling and a reducer are arranged on the base, and the motor and the reducer are connected to the base; the motor is connected to the reducer through a coupling; the driving gear set is placed at the upper end of the base, which is connected to the reducer; the speed ratio gear set is placed at the upper end of the base; two frames are arranged between the driving gear set and the speed ratio gear set; the front roller is placed between the two frames, and the two ends of the front roller are rotatably connected to the two frames respectively; the rear roller is arranged in parallel with the front roller; the two ends of the rear roller are rotatably connected to the two frames respectively; the glue receiving plate is placed at the upper end of the base; the pressing device is placed above the front roller, and the two ends of the pressing device are rotatably connected to the two frames respectively; the device uses the pressing device to perform rolling pressing, which can efficiently press the silicone between the front roller and the rear roller, improve production efficiency, and reduce the degree of danger of operation for operators.

[0004] However, the distance between the two rollers of the above-mentioned open mill is fixed, and cannot be adjusted according to different processing thicknesses, and the flexibility of use is poor and relatively limited. Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content
