[0018] like Figure 1-4 As shown, a rubber compound mixing device includes a frame 1, a tank 2 fixedly connected to the top of the frame 1, and a lifting assembly 3 provided on the top of the frame 1; the lifting assembly 3 includes a hydraulic cylinder 301, and a mounting plate 302 fixedly connected to one end of the hydraulic cylinder 301; a tank cover 303 is detachably connected to the top of the mounting plate 302, and fixing bolts 304 are provided on the outer wall of the tank cover 303; a feed inlet 305 is provided on the top of the tank cover 303, and an exhaust pipe 306 is provided on the top of the tank cover 303; the outer wall of the tank cover 303 is provided with... A stirring assembly 4 includes a gearbox 401, a reduction motor 402 mounted on the top of the tank cover 303, and a rotating rod 403 fixedly connected to the output shaft of the reduction motor 402 via a coupling. A first stirring blade 404 is provided on the outer wall of the rotating rod 403, and a second stirring blade 405 is provided on the outer wall of the rotating rod 403. A large gear 406 is fixedly connected to the outer wall of the rotating rod 403, and a small gear 407 is meshed with the outer wall of the large gear 406. A spiral rod 408 is fixedly connected to the inner wall of the small gear 407.

[0019] Through the above technical solution, the geared motor 402 drives the rotating rod 403 to rotate, which in turn drives the first stirring blade 404 and the second stirring blade 405 to stir the rubber compound. At the same time, the large gear 406 and the small gear 407 on the rotating rod 403 mesh, driving the spiral rod 408 to rotate synchronously. The spiral rod 408 conveys the bottom rubber compound upward, improving the mixing uniformity of the rubber compound and effectively solving the problems of bottom rubber compound deposition and local overheating, thus meeting people's demand for high-quality rubber compound mixing. Through the operation of the hydraulic cylinder 301, the mounting plate 302 is pushed upward, which in turn moves the tank cover 303. The tank cover 303 then moves the stirring assembly 4 out of the tank body 2, making it convenient for operators to inspect the stirring assembly 4 and clean the inside of the tank body 2. The operation is simple and easy to use.

[0020] Specifically, a discharge valve 5 is provided at the bottom of the tank body 2, and a heater 6 is provided at the bottom of the tank body 2. A sleeve 7 is fixedly connected to the outer wall of the tank body 2, and an inlet 8 and an outlet 9 are provided on the outer wall of the sleeve 7.

[0021] Through the above technical solution, a controller is installed on the frame 1, and the hydraulic cylinder 301 is fixed on the frame 1; a temperature sensor is installed on the inner wall of the tank 2, and a heater 6 is installed to heat the material in the tank 2 to meet the temperature rise requirements of the mixing process; the inlet 8 and outlet 9 are connected to the external water circulation system through pipelines and controlled by an electric valve. When the temperature sensor detects that the rubber temperature exceeds the set threshold, the controller automatically opens the electric valve, and cooling water flows from the inlet 8 into the sleeve 7 to cool the tank 2 through heat exchange. After the temperature returns to normal, the electric valve automatically closes, realizing dynamic and precise control of the rubber temperature and effectively avoiding the deterioration of rubber performance caused by abnormal temperature.

[0022] Specifically, there are two hydraulic cylinders 301, and the two hydraulic cylinders 301 are symmetrically arranged with the vertical line of the frame 1 as the axis of symmetry.

[0023] The above technical solution, by setting two hydraulic cylinders 301, can effectively support the can lid 303, making the movement of the can lid 303 more stable when it is raised or lowered.

[0024] Specifically, one end of the hydraulic cylinder 301 passes through the frame 1 and is connected to the mounting plate 302.

[0025] With the above technical solution, when the hydraulic cylinder 301 is working, it pushes the mounting plate 302 to move.

[0026] Specifically, the mounting plate 302 is fixed to the can cover 303 by fixing bolts 304, and one end of the fixing bolts 304 is threaded through the can cover 303 and extends into the mounting plate 302 for connection.

[0027] The above technical solution, by using fixing bolts 304, can effectively fix the can lid 303 to the mounting plate 302, facilitating installation and disassembly.

[0028] Specifically, the can lid 303 forms a rotating structure with the geared motor 402 and the rotating rod 403, and one end of the geared motor 402 extends into the gearbox 401 and is connected to the rotating rod 403.

[0029] With the above technical solution, the gearbox 401 is fixed on the can cover 303. Multiple bearings are installed inside the gearbox 401. When the reduction motor 402 works and drives the rotating rod 403 to rotate, the rotating rod 403 rotates more stably in the bearings. The rotation of the rotating rod 403 drives the large gear 406 to rotate, the large gear 406 drives the small gear 407 to rotate, and the small gear 407 drives the screw rod 408 to rotate. The screw rod 408 rotates more stably in the bearings on the gearbox 401.

[0030] Specifically, one end of the helical rod 408 extends into the gearbox 401 and connects with the pinion 407.

[0031] The above technical solution enables the pinion 407 to rotate effectively and drive the screw rod 408 to rotate; the first stirring blade 404 adopts a folded blade stirring blade, and the second stirring blade 405 is composed of multiple swept blades.

[0032] In use, first connect the device to an external power supply. The external power supply provides power to the device. After injecting raw rubber and compounding agents into the tank 2 through the feed inlet 305, the material in the tank 2 is heated by the heater 6 to reach a suitable mixing temperature. When stirring is required, the controller starts the reduction motor 402, driving the rotating rod 403 to rotate. The rotating rod 403 drives the first stirring blade 404 and the second stirring blade 405 to rotate, stirring the material. Simultaneously, the rotation of the rotating rod 403 drives the large gear 406 to rotate, which in turn drives the small gear 407 to rotate. The small gear 407 then drives the auger 408 to rotate. Rotating screw 408 conveys the rubber material at the bottom of tank 2 axially upwards. The rubber material lifted by screw 408 to the upper part of the internal area of ​​tank 2 will be drawn back into the mixing cycle under the stirring flow generated by the first stirring blade 404 and the second stirring blade 405, and fully contact and knead with other rubber materials to further improve the mixing uniformity. After the rubber material is mixed, the controller turns off the reduction motor 402 and the heater 6, and opens the discharge valve 5 at the bottom of tank 2. The mixed rubber material is discharged from the discharge port under the action of gravity. This completes the entire work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
