A suction cup 4 is fixedly connected to the bottom end of the support leg 3. These suction cups 4 can enhance the adsorption force between the device and the placement surface and further improve the stability of the device. A motor 5 is fixedly connected to the top end of the cylinder 1 to provide power for the operation of the device. A driving wheel 6 is fixedly connected to the driving end of the motor 5 so that the motor can drive the driving wheel 6 to rotate. A driven wheel 7 is rotatably connected to the front side inside the top end of the cylinder 1. A belt 8 is sleeved outside the driving wheel 6 and the driven wheel 7. A connecting rod 9 is fixedly connected to the bottom end of the driven wheel 7.

[0028] Referring to Figure 2 - Figure 4, the outer part of the connecting rod 9 is rotationally connected with an adapter rod 10 in a rotatable manner, the inner part of one side of the adapter rod 10 is rotationally connected with a rigid brush 11, the inner top of the cylinder 1 is fixedly connected with two fixing rods 12, and the inner part of the rigid brush 11 is slidably connected to the outside of the fixing rods 12 to ensure the accuracy and stability of the movement of the rigid brush 11. A first feeding hole 13 is arranged on the front side of the top of the cylinder 1 for adding specific materials. A filter plate 14 is fixedly connected inside the first feeding hole 13. The top of the rigid brush 11 is in contact with the bottom of the filter plate 14 to play a role in filtering materials. A second feeding hole 15 is fixedly connected to the rear side of the top of the cylinder 1. The driving end of the motor 5 is fixedly connected with a force transmission column 16.

[0029] Referring to Figure 3 and Figure 5 , a cleaning assembly for cleaning the inner wall is fixedly connected to the outside of the force transmission column 16. The cleaning assembly includes a plurality of stirring rods 17 which play an important stirring role during the material mixing process. A sliding rod 18 is slidably connected to the inner wall of one side of the stirring rod 17. A limiting disk 19 is fixedly connected to the adjacent sides of the plurality of sliding rods 18 to prevent the sliding rod 18 from extending or retracting excessively, ensuring the stability and reliability of the whole structure. The outside of the limiting disk 19 is slidably connected inside the stirring rod 17. A strong spring 20 is arranged inside the stirring rod 17, which has a powerful elastic potential energy and can provide a continuous and stable acting force for the whole cleaning assembly. One end of the strong spring 20 is fixedly connected to one side of the limiting disk 19 so that the elastic force of the spring can be effectively transmitted to the limiting disk 19. The other end of the strong spring 20 is fixedly connected to one side inside the stirring rod 17. The adjacent sides of the plurality of stirring rods 17 are respectively fixedly connected to the outside of the force transmission column 16. Cleaning plates 21 are fixedly connected to the opposite sides of the plurality of sliding rods 18. One side of the cleaning plate 21 is in contact with the inner wall of the cylinder 1 to be responsible for cleaning the inner wall. A discharge pipe 22 is fixedly connected to the bottom of the cylinder 1 to facilitate the smooth discharge of the mixed materials, realizing the continuity and high efficiency of the whole production process.

[0030] Referring to Figure 1 and Figure 6, the right side of the bottom end of the support ring 2 is fixedly connected with a cooling box 23, which ensures that there will be no loosening or displacement during operation, guaranteeing the reliability of the cooling function. A plurality of heat dissipation fins 24 are fixedly connected to the outside of the cooling box 23. These heat dissipation fins 24 greatly increase the contact area between the cooling box 23 and the outside air, enabling the heat generated inside the cooling box 23 to be dissipated more efficiently, thereby significantly improving the heat dissipation effect of the cooling box 23, ensuring that the coolant can always be maintained at a relatively low temperature, and providing strong guarantee for the continuous cooling of the device. The top end of the cooling box 23 is fixedly connected with a water pump 25. This firm connection method ensures that the water pump 25 can stably extract the coolant from the cooling box 23 during operation without leakage or loosening, providing a stable power source for the normal operation of the cooling system. The bottom end of the water pump 25 is fixedly connected to the right side of the top end of the support ring 2. The output end of the water pump 25 is fixedly connected with a transmission pipe 26, providing a reliable channel for the transmission of the coolant. The top end of the transmission pipe 26 is fixedly connected with a circulation pipe 27. The circulation pipe 27 is sleeved outside the cylinder body 1 to realize the cooling of the coolant, preparing for the next cooling cycle. The right end of the circulation pipe 27 is fixedly connected to the top end of the heat dissipation fins 24. The top end of the support ring 2 is fixedly connected with a receiving barrel 28.

[0031] Working steps

[0032] First, introduce powder-like materials through the first feeding hole 13 and liquid-like materials through the second feeding hole 15. After the material feeding is completed, start the motor 5 first. After the motor 5 starts, it drives the driving wheel 6 to rotate. Subsequently, under the rotation of the driving wheel 6, the belt 8 runs outside the driven wheel 7, thereby causing the driven wheel 7 to rotate inside the top end of the cylinder body 1. During the rotation of the driven wheel 7, the connecting rod 9 rotates, and its movement trajectory is similar to that of an eccentric wheel. Then, under the movement of the connecting rod 9, the connecting rod 10 is driven, so that the hard brush 11 cleans the filter plate 14 under the limiting action of the fixed rod 12, effectively preventing the powder from blocking the filter plate 14. At the same time, under the rotation of the driving wheel 6, the force transmission column 16 is also driven to rotate. The rotation of the force transmission column 16 drives the stirring rod 17 to mix the materials. During this process, the cleaning plate 21 slides on the inner wall of the cylinder body 1. During this process, due to the supporting force of the strong spring 20, the limiting disc 19 drives the sliding rod 18, making the cleaning plate 21 closely fit the inner wall of the cylinder body 1, and being able to more effectively clean the residual materials on the inner wall of the cylinder body 1. When the internal temperature of the cylinder body 1 rises during stirring and mixing, start the water pump 25 at this time. Under the starting action of the water pump 25, the coolant inside the cooling box 23 is driven to be transmitted from the transmission pipe 26 to the inside of the circulation pipe 27, and then flows inside the circulation pipe 27, taking away the heat generated by the cylinder body 1. Moreover, the presence of the heat dissipation fins 24 is to ensure that the coolant inside the cooling box 23 always maintains the best effect.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
