Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of open mill, concretely to an automatic rubber turning mechanism for open mill. BACKGROUND

[0002] The open mill is a key equipment in the rubber processing industry and plays an important role in modern industry. The open mill is mainly used for mixing and plasticizing rubber. In the production process of rubber products, it can fully mix various rubber raw materials uniformly to ensure the stability of product performance. For example, when manufacturing automobile tires, natural rubber is perfectly combined with carbon black, vulcanizing agent and other additives through the open mill, so that the tires have good wear resistance, tear resistance and elasticity. When operating, the staff puts the rubber raw materials between the two opposite rotating rollers of the open mill. The rollers rotate at different speeds to apply strong shear force to the rubber, so that it is repeatedly extruded and rolled in the roller gap. In this process, the raw materials are continuously stretched and deformed to achieve uniform mixing and plasticization. The open mill has the characteristics of flexible operation and can adjust the roller spacing, speed and other parameters at any time according to different rubber formulations and production requirements. It is not only suitable for large-scale industrial production, but also often used for experiments and small batch production in research institutions. Although more advanced equipment such as internal mixer has appeared with the development of science and technology, the open mill still occupies an important position in the rubber processing field due to its intuitive operation and convenient maintenance.

[0003] However, there are many inconveniences in the process of manual rubber turning when the open mill is used. When the open mill is started, the rubber continuously rolls between the two rollers, and the operator needs to put the rubber to be processed in time and turn it at the right time. However, this process is difficult to control. On the one hand, the rollers continue to rotate, the temperature and state of the rubber change constantly, and the timing of turning the rubber is fleeting; on the other hand, the operator needs to be close to the rotating roller, not only needs to pay attention to the direction and state of the rubber, but also needs to accurately judge the force and angle of turning the rubber. If not careful, it may cause uneven mixing of rubber and affect the quality of subsequent products. Moreover, long-term repeated turning action also easily makes the operator feel tired.
