Mixing is an essential step in the rubber product manufacturing process.

[0003] Existing mixing equipment suffers from poor mixing effects. Uneven temperature leads to significant differences in material heat distribution, which can easily cause localized scorching, resulting in increased waste and unstable performance. The low unloading efficiency and separate power design force operators to manually move heavy mixing devices (such as pots) out of the equipment for unloading. This not only consumes physical strength and increases manpower input, but the repetitive moving, unloading, and resetting operations are also time-consuming and labor-intensive, significantly reducing the overall efficiency of the unloading process. The problem addressed by this device is how to ensure a uniform and stable mixing temperature while enabling rapid unloading. Utility Model Content

A second handle 23 is installed on the top of the second sealing plug 24, and second screws 34 are spirally installed on both sides of the second handle 23. The sealing plugs effectively prevent dust leakage during mixing. To prevent heat loss and splashing of high-temperature raw materials, a fixed box 31 is installed at the bottom of the sealing cover 8. A first motor 30 is installed inside the fixed box 31. A rotating rod 22 is mounted on the first motor 30 via a drive shaft at its output end. Four blades 18 are fixedly mounted on both sides of the rotating rod 22, employing a symmetrical four-blade design. This enhances shear force while driving the raw materials to flow axially and radially in a coordinated manner, ensuring no mixing blind spots. A fixing ring 27 is fixedly mounted on the surface of the mixing tank 1. Fixing frames 29 are fixedly mounted on both sides of the fixing ring 27.

A third motor is fixedly installed inside the protective shell 2. The third motor is connected to the rotating shaft 3 via a transmission shaft at its output end. By adjusting the speed and direction of the third motor, the tilting angle of the mixing tank 1 can be precisely controlled, thereby adapting to the flow characteristics of materials with different viscosities and reducing residual material in the tank. A connecting frame 5 is fixedly installed on the left side of the second connecting plate 32. A bottom plate 4 is provided at the bottom of the mixing tank 1. A support column 9 is fixedly installed on the top of the bottom plate 4. A groove is opened on the surface of the support column 9. A first fixed plate 20 is movably installed inside the groove.

A connecting belt 10 is fixedly mounted on the bottom of the connecting block 13. A second protective shell 17 is fixedly mounted on the top of the base plate 4. A second motor is fixedly mounted inside the second protective shell 17. A gathering wheel 12 is fixedly mounted on the output end of the second motor through a transmission shaft. A second movable shaft is fixedly mounted on the back of the gathering wheel 12. One end of the second movable shaft is rotatably connected to a first support plate 11. The gathering wheel 12 and the connecting belt 10 are fixedly connected. The bidirectional constraint between the sliding groove and the fixed plate eliminates lifting offset. The meshing of the gear 14 and the rack belt 16 enables precise lifting. The fully enclosed motor drive can effectively reduce the failure rate.All electrical equipment in this device is powered by an external power source.

[0024] In one aspect of this embodiment, a first sealing plug 6 is installed inside the feed inlet, a first handle 7 is installed on the top of the first sealing plug 6, and first screws 15 are spirally installed on both sides of the first handle 7. The first sealing plug 6 can ensure that dust does not leak out during feeding, maintain a clean working environment and prevent heat loss. A second sealing plug 24 is installed inside the discharge outlet, a second handle 23 is installed on the top of the second sealing plug 24, and second screws 34 are spirally installed on both sides of the second handle 23. The second sealing plug 24 realizes rapid opening and closing control and can completely isolate air from entering during the stirring stage, thereby preventing rubber oxidation.

[0025] In one aspect of this embodiment, four blades 18 are fixedly installed on both sides of the rotating rod 22. The four symmetrically distributed blades 18 enhance the shear force, enabling the high-viscosity rubber raw material to be mixed synchronously in the radial and axial directions, eliminating dead corners.
