A brush bristle 403 is fixedly installed at the bottom end of the rotating shaft 402. The brush bristle 403 is in contact with the filter screen 602. By starting the rotary motor 401, the rotating shaft 402 is driven to rotate, thereby driving the brush bristle 403 above the filter screen 602 to rotate, smoothing the flour above the filter screen 403 and discharging it downward through the filter screen 602 for powdering. This ensures the uniformity of powdering and prevents the flour from clogging the filter screen 602 and affecting normal powdering.

[0027] In this embodiment, the bottom end of the rotating drum 901 extends into the interior of the conveying drum 6. A spirally arranged conveying blade 902 is fixedly installed on the outer surface of the rotating drum 901. The conveying blade 902 is in contact with the inner wall of the conveying drum 6. A transmission belt is installed between the rotating drum 901 and the output end of the servo motor 9. When spreading powder, the servo motor 9 is started to drive the rotating drum 901 to rotate, thereby driving the conveying blade 902 to rotate and pushing the flour inside the storage box 3 to the top of the filter screen 602. By precisely controlling the rotation speed of the servo motor 9, the amount of flour conveyed can be controlled, reducing flour waste.

[0028] In this embodiment, a through hole 7 is provided at the bottom of the conveying cylinder 6. An inclined guide plate 8 is fixedly installed on both sides of the conveying cylinder 6 corresponding to the through hole 7. The guide plate 8 is located at the feed end of the conveyor belt 2 and is in contact with the top of the conveyor belt 2. When the spring roll skin is placed on the conveyor belt 2 for conveying, the guide plates 8 on both sides limit the spring roll skin, so that the spring roll skin moves with the guide plate 8 to the bottom of the conveying cylinder 6 for powdering.

[0029] The working principle and usage process of this utility model are as follows: Spring roll wrappers are placed on conveyor belt 2 for conveying. The spring roll wrappers move with guide plate 8 to the bottom of conveyor cylinder 6. The servo motor 9 is started to drive the rotating drum 901 to rotate, thereby driving the conveyor blade 902 to rotate, pushing the flour inside the storage box 3 to the top of the filter screen 602. At the same time, the rotating motor 401 is started to drive the rotating shaft 402 to rotate, thereby driving the brush bristles 403 above the filter screen 602 to rotate, smoothing the flour on the filter screen 403 and discharging it downward through the filter screen 602, thus spreading the flour evenly. After spreading the flour, the spring roll wrappers continue to be conveyed with conveyor belt 2.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
