After mixing, the product is discharged from the device through the discharge port 13.

[0030] Example 2

[0031] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the feeding device 3 includes a support frame 31, which is fixedly connected to the top of the top cover 12. A raw material conveying pipe 32 is fixedly connected to the bottom of the support frame 31. A first bearing 33 is movably connected to the bottom of the raw material conveying pipe 32.

[0033] Example 3

[0034] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the cleaning device 4 includes a cleaning nozzle 41, which is fixedly connected to the bottom of the top cover 12.

[0036] The working principle of this raw material mixing and stirring device will be explained in detail below.

[0037] like Figure 1-6 As shown, the raw material pipe is connected to the feed pipe 34 via the connecting nut 35. The raw material then enters the stirring shaft 24 through the raw material conveying pipe 32. The rotation of the stirring shaft 24 improves the mixing of the raw material. After the raw material is added, the sealing cap 36 is tightened to prevent dust from entering. The drive motor 21 then drives the drive gear 22 to rotate, which in turn drives the driven gear 23. The stirring shaft 24 follows the driven gear 23, which in turn drives the stirring blades 25 to rotate, thus achieving mixing of the raw material. The stirring shaft 24 also drives the scraper 27 to rotate, thereby cleaning the inner wall of the container. The scraping prevents raw materials from adhering to the surface of the container, thereby changing the ratio of raw materials and improving product quality. The through holes on the surface of the stirring blade 25 can achieve global mixing optimization through local flow field disturbance, thus making the mixture more uniform. After mixing, the product is discharged from the device through the discharge port 13. Then, water is introduced into the device through the connecting pipe 42. When the water flows through the outer shell 411, it impacts the rotating blade 414. The rotating blade 414 drives the nozzle bracket 415 to rotate, thereby realizing the rotation of the cleaning nozzle 41. It can wash the inside of the device without dead angles. The high-pressure nozzle 416 can pressurize the water flow, which can wash more thoroughly.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
