[0046] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The differences are as follows: the first feeding hopper 41 and the second feeding hopper 42 both include a hopper body 431, a rotating shaft 432, a scraper 433, a stirring roller 434, a rotating tube 435, a driving sprocket 436, a driven sprocket 437, a transmission chain 438, a rotating motor 439, and a feeding motor 4322; a vertical discharge pipe 4311 is provided at the bottom of the hopper body 431; a vertical auger 4321 cooperating with the discharge pipe 4311 is coaxially mounted at the bottom end of the rotating shaft 432, so as to ensure the stable output of the powder; the top end of the rotating shaft 432 is coaxially fixedly connected to the output shaft of the feeding motor 4322; the output The motor outputs torque to the vertical auger 4321 through the rotating shaft 432; the rotating tube 435 is sleeved in the middle of the rotating shaft 432 and is rotatably connected to the rotating shaft 432; the driving sprocket 436 is coaxially fixedly connected to the output shaft of the rotating motor 439; the rotating motor 439 outputs torque to drive the driving sprocket 436 to rotate; the passive sprocket 437 is coaxially fixedly connected to the upper end of the rotating tube 435; the driving sprocket 436 and the passive sprocket 437 are connected through the transmission chain 438; the rotating driving sprocket 436 drives the passive sprocket 437 to rotate through the transmission chain 438; the passive sprocket 437 drives the rotating tube 435 to rotate; the scraper 433 is attached to the inner wall of the bucket 431 and is connected to the rotating tube 43 5 is connected to the side of the lower end of the rotating tube 435, and can clean the inner wall of the bucket body 431 with the rotation of the rotating tube 435; the stirring roller 434 is arranged perpendicular to the rotating tube 435, connected to the side of the lower end of the rotating tube 435, and can stir the powder in the bucket body 431 with the rotation of the rotating tube 435; the power source of the vertical auger 4321, the scraper 433 and the stirring roller 434 in this embodiment are two independent power sources; in this way, in the bucket body 431, the scraper 433 can clean the powder on the inner wall of the bucket body 431, and the stirring roller 434 can stir the powder, and the vertical auger 4321 can output the powder to the vertical tube 712, which can be executed separately; The hopper can adapt to the needs of different powder amounts in the hopper body 431; when there is more powder in the hopper body 431, the excessive powder is squeezed on the upper end of the vertical auger 4321, which is easy to lose fluidity and cause the output of the vertical auger 4321 to be interrupted; therefore, the scraper 433 and the stirring roller 434 rotate with the vertical auger 4321 to fully stir the powder in the hopper body 431, thereby ensuring the stable output of the vertical auger 4321; when there is less powder in the hopper body 431, the rotation of the scraper 433 and the stirring roller 434 is of no help to the transportation of the vertical auger 4321, but will make the vertical auger 4321 feed unevenly, so that only the vertical auger 4321 is needed.
