The connecting hole 88 is set away from the center of the inner ring body 89. Preferably, the second rib 83, the third rib 84 and the fourth rib 85 are respectively provided with a through hole 87. After being stirred by the stirring member 28, the powder material enters the feeder 3.

[0036] Also refer to Figure 3 and Figure 8The feeder 3 includes a housing 31, an end cover 32, a rotating shaft 35, a driven member 33, a transmission member 34, a material distribution plate 36, a scraper 37 and an elastic member 38. The housing 31 is roughly a hollow cylinder with an open end. One side of the housing 31 is mounted on the lower end of the mounting cylinder 21 and is connected to the interior of the mounting cylinder 21. The motor 23 is mounted on the outer side of the housing 31. The end cover 32 is mounted on the open end of the housing 31. The rotating shaft 35 is rotatably supported on the housing 31 and the end cover 32. The driven member 33 is mounted on one end of the rotating shaft 35 protruding from the end cover 32. The first driving member 241 drives the driven member 33 to rotate through the transmission member 34. Preferably, the first driving member 241 and the driven member 33 are respectively pulleys or sprockets, and the transmission member 34 is a belt or chain. A plurality of material distribution plates 36 are mounted on the rotating shaft 35. A scraper 37 is mounted on one end of the material distribution plate 36 away from the rotating shaft 35. An elastic member 38 is connected between the scraper 37 and the material dividing plate 36. Preferably, a mounting hole 361 is provided at one end of the material dividing plate 36 away from the rotating shaft 35, one end of the elastic member 38 is mounted in the mounting hole 361, and the other end of the elastic member 38 is connected to the scraper 37. Preferably, the elastic member 38 is a spring. The scraper 37 is sleeved on the end of the material dividing plate 36 away from the rotating shaft 35. The scraper 37 is generally a hollow cavity with one end open. The end of the scraper 37 facing away from the dividing plate 36 is set to a triangle, and the two sides of the triangle are respectively set to a first inclined surface 371 and a second inclined surface 372, so that when the scraper 37 rotates with the dividing plate 36, under the action of the corresponding inclined surfaces, the inner side of the shell 31 can smoothly press the scraper 37 toward the dividing plate 36. At this time, the elastic member 38 is compressed, and as the scraper 37 rotates, the powder material adhered to the inner side of the shell 31 can be scraped off to prevent the powder material from sticking to the inner side of the shell 31.

[0037] When in use, the motor 23 runs, and the first driving member 241 drives the dividing plate 36 of the feeder 3 to rotate to control the amount of powder material entering the conveying pipe 4, and the second driving member 242 drives the stirring member 28 to rotate to effectively stir the powder material and prevent the powder material from accumulating in the conveying pipe. Specifically, the motor 23 is running, and the second driving member 242 drives the slider 261 to move back and forth through the connecting rod 25, thereby driving the moving rod 271 of the pushing assembly 27 to move back and forth. When the moving rod 271 moves back and forth, the first rotating wheel 273 and the second rotating wheel 274 drive the stirring member 28 to rotate relative to the mounting cylinder 21 through the inner ring body 89, thereby stirring the powder material passing through the mounting cylinder 21. After being stirred by the stirring member 28, the powder material enters the feeder 3, and the first driving member 241 drives the driven member 33 to rotate through the transmission member 34, and the driven member 33 drives the rotating shaft 35 to rotate, so that the dividing plate 36 on the rotating shaft 35 rotates to control the amount of powder material entering the conveying pipe 4; when the dividing plate 36 rotates, the scraper 37 rotates accordingly, and under the action of the corresponding inclined surface, the inner side of the shell 31 can smoothly press the scraper 37 toward the dividing plate 36.
