[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4As shown, this utility model discloses an integrated mixing and granulation machine, comprising a support assembly, a stirring device, a mixing device, a granulation device, and an ejection device. The stirring device is located on the upper surface of the support assembly to facilitate stirring of materials. The mixing device is located on the upper surface of the support assembly to assist the stirring device in stirring. The granulation device is located on the upper surface of the support assembly. The ejection device is located on the inner wall of the stirring device to facilitate ejection of the stirred material. The ejection device includes a handwheel body 51, a handwheel coupling 52, a screw ejection reducer 53, and a screw ejection mold rod 54. The handwheel body 51 is located at one end of the stirring device, the handwheel coupling 52 is located on the inner wall of the handwheel, the screw ejection reducer 53 is located at one end of the handwheel coupling 52, and the screw ejection mold rod 54 is located on the inner wall of the screw ejection reducer 53.

[0020] Specifically, after mixing or granulation, the handwheel body 51 is operated, which drives the screw ejector reducer 53 via the handwheel coupling 52. The reducer converts the rotational torque into axial thrust, pushing the screw ejector die rod 54 to move axially, ejecting the granulation screw 42 from the transmission rod 43, and removing residual material from the rotor shaft and groove wall, preventing material from solidifying and clogging. This design significantly shortens the time for screw cleaning, replacement, or maintenance, reduces equipment downtime, and improves production continuity; at the same time, it reduces the difficulty of manual operation, reduces the risk of material residue or equipment failure due to incomplete cleaning, and extends the screw's service life.

[0021] The stirring device includes a motor mounting base 21, a first servo motor A22, a first coupling A23, and a first stirring rotor shaft A24. The motor mounting base 21 is located on the upper surface of the support assembly. The first servo motor A22 is located on the inner wall of the motor mounting base 21. The first coupling A23 is located at one end of the first servo motor A22. The first stirring rotor shaft A24 is located between the first coupling A23 and the internal mixing device. The handwheel body 51 is located at one end of the motor mounting base 21. It also includes a second servo motor B25, which is located on the inner wall of the motor mounting base 21. One end of the second servo motor B25 is provided with a second coupling B26. One end of the second coupling B26 is provided with a second stirring rotor shaft B27, which is located between the second coupling B26 and the internal mixing device.

[0022] Specifically, the first servo motor A22 drives the first stirring rotor shaft A24 through the first coupling A23, and the second servo motor B25 drives the second stirring rotor shaft B27 through the second coupling B26. The two rotor shafts rotate in opposite directions within the mixing tank 31 at a preset differential speed ratio, achieving efficient mixing and plasticization of the raw materials through shearing, extrusion, and kneading.

[0023] The rotational speed of the servo motor is independently controlled, and the rotational speed ratio of the two rotor shafts is adjusted in real time to optimize material dispersion and uniformity. The gap control between the rotor shaft and the inner wall of the mixing tank 31, together with the rigid support of the mixing support 32 and the support rod 34, ensures that the material is subjected to shearing, compression and friction at high temperature to complete plasticization.

[0024] The mixing device includes a mixing tank 31, a mixing support 32, a shaft support 33, and a support rod 34. The mixing tank 31 is located on the upper surface of the support assembly, and the support rod 34 is located at one end of the mixing tank 31. Multiple support rods 34 are provided and spaced apart. The shaft support 33 is located on the upper surface of the support assembly and is connected to the support rod 34. The mixing support 32 is located on the upper surface of the support assembly. The first stirring rotor shaft A24 is located between the first coupling A23 and the mixing tank 31, and the second stirring rotor shaft B27 is located between the second coupling B26 and the mixing tank 31.

[0025] Specifically, the internal mixing device, through the reasonable layout of the internal mixing support 32, shaft support 33 and support rod 34, combined with the rigid support of the support components, ensures the concentricity of the internal mixing tank 31 and the stirring rotor shaft, reduces equipment wear and noise caused by vibration or eccentricity during operation, and improves the stability and service life of the equipment.

[0026] The mating structure between the rotor shaft and the inner wall of the mixing tank 31 performs strong shearing, extrusion and kneading on the material, so that the raw materials and binder are fully mixed and uniformly plasticized, ultimately forming a uniform feed with good flowability.

[0027] The upper surface of the mixing tank 31 is provided with a dustproof component for dust prevention. The dustproof component includes a dust cover 61 and a sealing plate 62. The dust cover 61 is located on the upper surface of the support component, and the sealing plate 62 is located on the upper surface of the mixing tank 31 to facilitate cooperation with the dust cover 61.

[0028] Specifically, when the dust cover 61 is in operation, the drive motor (not shown) on the inner wall of the dust cover 61 will drive the dust cover 61 to seal with the sealing plate 62, effectively preventing the dust generated during the mixing process from overflowing, avoiding dust pollution of the workshop environment, and protecting the health of operators; at the same time, it reduces the entry of impurities into the equipment, reduces the risk of equipment wear, meets environmental protection requirements, and improves production safety.

[0029] The granulation device includes a granulation motor 41, a granulation screw 42, and a transmission rod 43. The granulation motor 41 is located on the upper surface of the support assembly, the transmission rod 43 is located at the output end of the granulation motor 41, and the granulation screw 42 is located at one end of the transmission rod 43.

[0030] Specifically, the plasticized material enters the granulation device through the bottom outlet of the mixing tank 31. The granulation motor 41 drives the transmission rod 43 to rotate, which in turn drives the granulation screw 42 to rotate at high speed. The threaded structure of the granulation screw 42 evenly conveys the material to the die head (not shown), and it is extruded into strips through the die head orifice. The matching pelletizing device (not shown) cuts the strip material into uniform particles, realizing continuous granulation.

[0031] The support assembly includes a frame 11 and a worktable 12. The worktable 12 is located on the upper surface of the frame 11, the mixing tank 31 is located on the upper surface of the worktable 12, the shaft support 33 is located on the upper surface of the worktable 12, the mixing support 32 is located on the upper surface of the worktable 12, and the dust cover 61 is located on the upper surface of the worktable 12. A fixing plate 13 is provided at one end of the worktable 12 to facilitate the support of the granulation motor 41, and the granulation motor 41 is located on the upper surface of the fixing plate 13.

[0032] Specifically, the frame 11 and workbench 12 of the supporting components provide rigid support, and each device (mixing, granulation, ejection) has an independent modular layout, which facilitates maintenance and upgrades.

[0033] The ejection device, through the coordinated action of the handwheel body 51, handwheel coupling 52, screw ejection reducer 53, and screw ejection mold rod 54, can quickly eject the granulating screw 42 from the granulation module without complex disassembly operations. This design significantly shortens the time for screw cleaning, replacement, or maintenance, reduces equipment downtime, and improves production continuity; at the same time, it reduces the difficulty of manual operation, reduces the risk of material residue or equipment failure due to incomplete cleaning, and extends the screw's service life.
