Description

Technical Field

[0001] The utility model relates to the technical field of rubber material processing, in particular to a rubber mixing machine for processing environmentally friendly rubber materials. Background Art

[0002] The rubber mixing mills used in rubber processing are divided into two categories: open and closed. Among them, the open rubber mixing mill has two horizontally arranged rollers. The machine for mixing rubber between the two rollers is referred to as an open mixing mill. The material is pulled into the gap between the two relatively rotating rollers at different linear speeds under the action of friction. The material 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 mixing rubber. In order to facilitate the cleaning of the residual rubber on the mixing roller, there is a technology that proposes a related cleaning structure to assist in cleaning the surface of the mixing roller. For example, there is a utility model patent with a publication number of CN216682852U, which proposes a rubber open rubber mixing mill. By setting a first cleaning mechanism, the residual rubber on the mixing roller can be automatically cleaned. Compared with manual cleaning of this part of the rubber, it saves time and effort and greatly improves the cleaning efficiency.

[0003] From the above disclosed technical content, theoretically speaking, the implementation of the relevant technical structure is conducive to the removal of rubber from the rubber mixing roller. According to the description in the above disclosed technical content, the rubber from the rubber mixing roller is removed by moving the arc knife horizontally on the rubber mixing roller. However, after long-term use of the arc knife, the rubber itself has a certain viscosity. When the arc knife cleans the rubber, the rubber will also adhere to the surface of the arc knife. As the amount of rubber adhered to the arc knife increases, the cleaning effect of the arc knife with rubber on the rubber mixing roller will decrease. At the same time, the arc knife is installed on the arc plate in a fixed connection. At this time, it is inconvenient for the staff to disassemble the arc knife for cleaning, thereby reducing the flexibility of the arc knife in actual use. Utility Model Content

At this time, the scraper 2 scrapes off the residual rubber on the surface of the rubber mixing roller 1. Then, when the scraper 2 is worn or needs to be glued to its surface When cleaning the attached rubber material, press the spring buckle 7 to move it toward the inside of the lifting block 4 until the lifting block 4 is separated from the locking block 6, and then press the pressing plate 27 to retract the lifting block 4 into the inside of the fixed block 3.
