[0025] Reference Figures 1-5 A temperature control device for a rubber mixing mill includes a rubber roller 2, a heating rod 11 inside the rubber roller 2, connecting cylinders 5 fixedly sleeved at both ends of the rubber roller 2, multiple support mechanisms sleeved on the heating rod 11, the support mechanisms including multiple rollers 13, connecting plates 12 provided at both ends of the multiple rollers 13, the connecting plates 12 fixedly sleeved on the heating rod 11, the rollers 13 rolling along the inner wall of the rubber roller 2, and a temperature sensor 10 provided on the inner wall of the rubber roller 2;
[0026] One of the connecting cylinders 5 is connected to the first connecting cavity 3, and the other connecting cylinder 5 is connected to the second connecting cavity 4. A support 1 is fixedly connected to the bottom of both the first connecting cavity 3 and the second connecting cavity 4. Both ends of the heating rod 11 are fixedly connected to the connecting shaft 9. A cooling mechanism is provided on the connecting shaft 9 in the second connecting cavity 4. The cooling mechanism includes a fan 15 rotatably mounted on the connecting shaft 9. The fan 15 is driven by a second motor 18. The connecting shaft 9 is fixedly mounted on the rubber mixing machine and is fixedly mounted in the first connecting cavity 3 and the second connecting cavity 4 by the mounting shaft.
[0027] A fixing plate 20 is fixedly connected to the inner wall of the second connecting cavity 4. A hole 19 is provided on the fan 15 for the connecting shaft 9 to pass through. The fan 15 is rotatably connected to the fixing plate 20 via a mounting ring. A second gear 16 is fixedly sleeved on the mounting ring, and a third gear 21 is meshed on one side of the second gear 16. A second motor 18 is fixedly mounted on the fixing plate 20, and the drive end of the fixing plate 20 is fixedly connected to the third gear 21. When cooling is required inside the rubber roller 2, the second motor 18 drives the third gear 21 to rotate via its drive end. The third gear 21 drives the meshing second gear 16 to rotate. As the second gear 16 rotates, it drives the fan 15 to rotate synchronously via the mounting ring. The rotating fan 15 has a cooling effect on the rubber roller 2, effectively cooling it when it is overheated.
[0028] A driving mechanism is provided on the first connecting cavity 3 to drive the rubber roller 2 to rotate. The connecting cylinder 5 is connected to the first connecting cavity 3 through a first connecting ring 14. One side of the first connecting ring 14 is fixedly connected to the connecting cylinder 5 near the first connecting cavity 3, and the other side of the first connecting ring 14 is rotatably connected to the first connecting cavity 3. The second connecting cavity 4 is connected to the connecting cylinder 5 near the second connecting cavity 4 through a third connecting ring 17. One side of the third connecting ring 17 is fixedly connected to the second connecting cavity 4, and the other side is rotatably connected to the connecting cylinder 5 near the second connecting cavity 4. Under the action of the driving mechanism, the first connecting ring 14 can be driven to rotate, and the first connecting ring 14 drives the fixedly connected rubber roller 2 to rotate, thus enabling continuous mixing during rubber compounding, and the rubber roller 2 can rotate continuously.
[0029] The drive mechanism includes a first motor 8 and a first gear 6. The first motor 8 is fixedly connected to the first connecting cavity 3, and the drive end of the first motor 8 is fixedly connected to the first gear 6. The first connecting ring 14 has a toothed groove 7 on its outer periphery near the first connecting cavity 3, and the first gear 6 meshes with the toothed groove 7. The first motor 8 can drive the first gear 6 to rotate through its drive end, and the first gear 6 drives the first connecting ring 14 to rotate through meshing with the toothed groove 7. In turn, the first connecting ring 14 drives the rubber roller 2 to rotate.
[0030] The roller 13 is rotatably connected to the connecting plates 12 on both sides via a rotating shaft. The diameter of the connecting plates 12 is smaller than the inner diameter of the rubber roller 2. When the rubber roller 2 rotates, the roller 13 can roll along the inner wall. Due to the small size of the connecting plates 12, direct friction between the connecting plates 12 and the rubber roller 2 can be avoided. Furthermore, the heating rod 11 is in direct contact with the rubber roller 2 through the connecting plates 12 and the roller 13, thus providing direct heat conduction.
[0031] The first connecting ring 14 has two sides formed by a recess. A bolt is installed on one side, and a toothed groove 7 is provided on the other side. The first connecting cavity 3 is rotatably connected to the inner wall of the first connecting ring 14. Both the ends of the first connecting cavity 3 and the second connecting cavity 4 are provided with movable covers. The first connecting ring 14 is configured with a recessed structure so that it can be connected to the connecting cylinder 5 on one side and to the first connecting cavity 3 on the other side.
[0032] During use, the rubber roller 2 needs to rotate continuously to heat the rubber. The first motor 8 drives the first gear 6 to rotate via the drive end. The first gear 6 meshes with the tooth groove 7 to drive the first connecting ring 14 to rotate. The first connecting ring 14 drives the rubber roller 2 to rotate, thereby enabling the rubber to be processed. The other end of the rubber roller 2 is connected to the second connecting cavity 4 via another connecting cylinder 5. The support 1 is fixedly installed inside the rubber mixing mill. During the rotation of the rubber roller 2, the heating rod 11 is heated. Heat conduction within the space of the rubber roller 2 effectively heats the wound rubber. When the rubber roller 2 rotates, the heating rod 11 remains stationary. The heating rod 11 is circulated... The electric heating has a heating effect on the entire rubber roller 2. The support mechanism fixedly connected to the heating rod 11 also conducts the heat energy of the heating rod 11. As the rubber roller 2 rotates, the roller 13 will roll accordingly. The rolling roller 13 moves around the inner wall of the rubber roller 2, which can be heated evenly. The temperature sensor 10 is used to detect the temperature of the rubber roller 2. The temperature sensor 10 is existing technology. It can detect the temperature and transmit the temperature data. According to the detected temperature, the heating of the heating rod 11 and the heat dissipation of the fan 15 can be adaptively controlled. The rubber is in direct contact with the rubber roller 2, which can ensure that the heat is efficiently and directly transferred to the rubber, avoid heat loss, and improve the heat utilization rate.
[0033] When the temperature is detected to be too high, or when a higher temperature is not required, the second motor 18 drives the third gear 21 to rotate via the drive end. The third gear 21 meshes with the second gear 16, driving the second gear 16 to rotate. The second gear 16 drives the fan 15 to rotate synchronously, accelerating the air circulation inside the rubber roller 2, thereby dissipating excess heat inside the rubber roller 2. The first connecting cavity 3, the second connecting cavity 4, and the rubber roller 2 are interconnected. Movable covers are added to both ends of the first connecting cavity 3 and the second connecting cavity 4. The presence of the movable covers does not affect the normal operation of the rubber roller 2, and can also be used to assist in the heating and heat dissipation of the rubber roller 2.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
