Description

Technical Field

[0001] The utility model relates to the technical field of mixed rubber, in particular to an automatic cutting and mixing device for mixed rubber. Background Art

[0002] Rubber compounding is a common production process in the rubber industry, involving the mixing and molding of rubber materials. In traditional rubber compounding production, in order to promote uniform mixing and processing and molding, the rubber raw materials and other additives are fully mixed by cutting the rubber and then putting them back, so that the various ingredients can be fully integrated and dispersed, thereby improving the quality and performance of rubber products.

[0003] However, the traditional cutting and mixing method is time-consuming and laborious. In the production process of the compound rubber, not only the rubber needs to be cut and mixed, but also a certain proportion of water needs to be added to the mixed rubber for cooling according to the temperature change to meet the requirements of the production process. This will increase the manual operation cost and workload in production and reduce production efficiency. Utility Model Content

[0028] See also Figure 4 The utility model provides a technical solution: further, the rotating member includes a driven gear 11 fixedly mounted on the mounting block 8, a driving gear 12 is meshed on one side of the driven gear 11, the driving gear 12 and the driven gear 11 are both located inside the fixed housing 3, and a motor is provided on the driving gear 12 for driving the driving gear 12 to rotate. The method of driving the driving gear 12 to rotate by a motor here is a prior art, so it is not described.

[0029] Furthermore, two mounting blocks 8 are provided, and the two mounting blocks 8 are symmetrical to each other with the midpoint of the driven gear 11 as a reference.

[0030] Furthermore, the mounting block 8 is composed of three parts: a fixed shaft 81, a clamping block 82 and an anti-skid pad 83.

[0032] Working principle: Before using the automatic cutting and mixing device for mixing rubber, the telescopic fixing rod 5 can be snap-fitted and installed on the mixing machine body 1, and the position of the mounting shell 2 can be adjusted to bring the cutting blade 62 close to the mixing shaft on the mixing machine body 1, and then the mounting block 8 can be snap-fitted on the turntable of the mixing machine body 1 that controls the water valve switch. After completing the preparation work, during the mixing process, the cutting screw 10 can be controlled to rotate, so as to drive the cutting blade 62 on the fixing block 61 to slide along the direction of the guide rod 9 to cut the rubber on the mixing shaft, and then the baffle plate 7 can be used to allow the rubber that falls after cutting to be re-mixed during the accumulation process, so as to effectively control the cutting and mixing process of the rubber material, reduce manual operation, and reduce labor costs. At the same time, the device has a simple structure and low manufacturing cost, and is convenient to be installed on the existing mixing machine body 1, reducing replacement costs.

[0033] And considering that during the rubber mixing process, the rubber material will generate a lot of heat due to friction, causing the temperature to rise and affecting the properties of the material, the mounting block 8 can be designed to be installed on the turntable of the mixing machine body 1 that controls the water valve switch. According to the actual detected temperature, the motor on the active gear 12 is controlled by a signal to rotate and drive the driven gear 11. The driven gear 11 drives the mounting block 8 on the surface to drive the turntable that controls the water valve switch to rotate, thereby automatically controlling the addition of water according to the temperature conditions, cooling the rubber material while reducing the labor cost of manual labor. In addition, combined with the automatic cutting and mixing method of the rubber compound, the efficiency and product quality of rubber mixing production can be further effectively improved, and the production cost can be reduced.
