[0016] The following specifically describes the detailed embodiments of the utility model with reference to the drawings.

[0017] Embodiment:

[0018] The specific implementation of an open rubber mixer according to the present utility model is shown in the accompanying drawings. It mainly includes a base 1. On the left side of the base 1, a first roller 2 and a second roller 3 are arranged side by side. The first roller 2 and the second roller 3 are respectively driven to rotate by a first variable-frequency motor 4 and a second variable-frequency motor 5. The first variable-frequency motor 4 and the second variable-frequency motor 5 are installed on the right side of the base 1. The first variable-frequency motor 4 and the second variable-frequency motor 5 are respectively connected to a first hard tooth surface reducer 10 and a second hard tooth surface reducer 11 through a first coupling 8 and a second coupling 9. The first hard tooth surface reducer 10 and the second hard tooth surface reducer 11 are respectively connected to the first roller 2 and the second roller 3 through a first universal coupling 12 and a second universal coupling 13. By adopting the transmission of double motors, double hard tooth surface reducers and universal couplings, the individual speed regulation of the two rollers can be realized.

[0019] The first roller 2 and the second roller 3 are respectively installed on the base 1 through a distance adjustment device 6. Specifically, the distance adjustment device 6 includes a moving seat for installing the roller, a lead screw threadedly connected to the moving seat, a worm wheel connected to the lead screw, and a worm meshing with the worm wheel. A hand wheel 6a is provided at the end of the worm. When it is necessary to move the first roller 2 or the second roller 3, only the corresponding hand wheel 6a needs to be rotated. The hand wheel 6a can drive the worm to rotate. By using the worm to drive the worm wheel to rotate, the lead screw further drives the moving seat to move as the worm wheel rotates, thereby realizing the movement of the roller.

[0020] In this embodiment, displacement sensors are provided on both moving seats for installing the rollers. By using the hand wheel in cooperation with the worm and worm wheel, the two rollers can be adjusted respectively. With the displacement sensors equipped to detect the moving distance, accurate distance adjustment can be realized.

[0021] Rotary joints 7 are provided at one end of both the first roller 2 and the second roller 3. A hot water storage cavity and a heat-conducting oil storage cavity communicated with the rotary joint 7 are respectively provided inside the first roller 2 and the second roller 3. The structures of the hot water storage cavity and the heat-conducting oil storage cavity are the same.

[0022] Combined with Figure 4 、 Figure 5As shown, taking the first roller 2 as an example, the structure of the hot water storage cavity mainly includes a middle cavity 15 provided in the middle of the roller. One end of the middle cavity 15 extends to the end of the roller and communicates with the outside, and the other end is located inside the roller. Inside the roller, there are a first through cavity 16 and a second through cavity 17 close to the surface of the roller. The lengths of the first through cavity 16 and the second through cavity 17 extend along the length direction of the roller, and their longitudinal sections are arc-shaped. The first through cavity 16 and the second through cavity 17 are symmetrical to each other. The first through cavity 16 and the second through cavity 17 are respectively communicated with the middle cavity 15 through a plurality of spaced connection cavities 18, and the first through cavity 16 and the second through cavity 17 are also communicated with each other through a plurality of spaced third through cavities 19. Hot water or heat-conducting oil can be introduced into the roller through the rotary joint 7, enter through the middle cavity 15, be respectively distributed into the first through cavity 16 and the second through cavity 17 through a plurality of connection cavities 18, and under the action of the third through cavity 19, the conduction between the first through cavity 16 and the second through cavity 17 is realized, so as to achieve the overall heating of the roller. One of the two rollers uses water heating temperature control, and the other uses heat-conducting oil heating temperature control, which can realize different roller temperature adjustments, has a wide application range, and can improve the rubber mixing effect.

[0023] In addition, a material receiving tray 14 is also provided on the base 1 below the first roller 2 and the second roller 3 for receiving materials.
