[0023] Embodiment 2: Figure 1 and Figure 4 As shown, a fan soundproof cover 10 is arranged at the top of the pulse recovery frame 19, an exhaust fan 16 is arranged inside the fan soundproof cover 10, and a silencer component opposite to the exhaust fan 16 is arranged at the notch at the top of the fan soundproof cover 10; wherein the silencer component includes structural parts such as a silencer top plate 17 and a grille-type silencer frame 18, the silencer top plate 17 is connected to the notch at the top of the fan soundproof cover 10 and the grille-type silencer frame 18 corresponds to the air outlet position of the notch at the top of the fan soundproof cover 10, so that the wind noise of the air outlet can be minimized and the spatial position distribution method can silence the noise generated by the exhaust fan 16 itself.

[0024] In this implementation, to facilitate the operation of the pulley powder collection box, improve the convenience of powder access, and enable the pulley powder collection box 13 to effectively collect powder, the connection tightness between the powder feeding hopper 11 and the filter frame 9 is increased.
