[0025] Specifically, powder enters into receiving hopper 2 from the entrance of receiving hopper 2, then falls to screening net 9 and is preliminarily screened, at this time, motor A 4 runs and drives telescopic rod 42 to rotate, and telescopic rod 42 is elongated so that combing tooth 81 contacts screening net 9, which can comb the residual material on screening net 9, wavy stirring rod 8 can adapt to impurities of different heights, ensure that the residual material can be spread out, reduce that larger residual material and impurities block the holes of screening net 9, thereby causing the phenomenon that powder cannot fall, reduce powder waste, and improve impurity removal efficiency.

[0026] Embodiment 2:

[0027] Please refer to Figures 1-3The receiving hopper 2 is provided with a clamping groove A22 on both sides, a waste box 7 is clamped and connected in the clamping groove A22, a slot 72 is provided on one side of the waste box 7, the position of the slot 72 corresponds to the screening net 9, an electromagnetic plate 71 is fixedly connected to the inner wall of the slot 72, a motor B6 is fixedly connected to one side of the supporting plate 1, a rotating shaft 61 is fixedly connected to the output end of the motor B6, a rotating rod 62 and a pushing rod 63 are fixedly connected to both sides of the rotating shaft 61, the pushing rod 63 is in contact with the screening net 9, a clamping groove B21 is provided on one side of the receiving hopper 2, a clamping block 10 is clamped and connected in the clamping groove B21, one end of the clamping block 10 is clamped and connected with the screening net 9, a baffle 41 is sleeved on the outer surface of the telescopic rod 42, and a receiving box 5 is fixedly connected to one side of the supporting plate 1.
