[0019] The outer wall of the fixed seat 73 is provided with two fixed holes 74 on the front and back sides, the two fixed holes 74 on the same side are distributed upward and downward, a bolt 79 penetrates through the fixed holes 74, the bolt 79 is threadedly matched with the fixed holes 74, and the end of the bolt 79 is abutted against the outer wall of the rotating shaft 71.
[0020] The discharge port 4 is connected with a material conveying device.
[0021] When the powder in the hopper 1 flows normally without arching, the flexible piece 78 remains in a contracted state and is tightly attached to the outer wall of the fixed seat 73, since one end of the flexible piece 78 is clamped and the other end cooperates with the inner wall of the hopper 1 with a gap, they will not interfere with the normal falling of the powder.
[0022] Once the powder in the hopper 1 arches or is partially blocked to form holes, the holes will hinder the continuous falling of the powder.
[0023] At this time, the deceleration motor 6 starts to drive the rotating shaft 71 to rotate. Since one end of the flexible sheet 78 is fixed and the other end is freely extended and kept a gap with the inner wall of the hopper 1, when the rotating shaft 71 rotates, the flexible sheet 78 will also rotate.
[0024] Since the flexible sheet 78 has elasticity, when they rotate to the arching or blocking position, they will stretch out by their own elasticity, contact the arching material and push it down, thereby eliminating the cavity and restoring the normal flow of the powder.
[0025] The deceleration motor 6 continues to operate to drive the flexible sheet 78 to rotate continuously, ensuring that the powder in the hopper 1 can continuously and smoothly flow out.
[0026] When the powder flow in the hopper 1 returns to normal and arching no longer occurs, the flexible sheet 78 will again shrink to the initial state and will not have any impact on the discharging.
