[0019] The sieving mechanism includes a sieving box 9, a vibrating frame 10, and a powder sieve frame 11. The sieving box 9 is connected to the bottom of the processing box 1.

[0020] The screw conveyor mechanism includes a feeding cylinder 12, a screw feeding shaft 13, and a feeding motor 14. The feeding cylinder 12 is located below the connection port 3.

[0022] The weighing and feeding mechanism includes a fixed hinge seat 18, a hinge telescopic rod 19, a hinge support plate 20, a weighing sensor 21, a material tray 22, and a feeding port 23.

A conveyor belt can also be arranged below the feeding port to transport the weighed material, or it can be directly connected to the material-using equipment for quantitative feeding.
[0023] When using this powder rotor quantitative feeder, the powder is added from the feed inlet. First, the grinding shell driven by the rotary motor rotates to crush the lumpy material in the powder. Then, it passes through the powder screen frame below to make the powder particle size uniform. The powder after sieving falls to the screw conveyor below for feeding, and the material enters the distribution channel.
[0024] First, the rotating switching plate in the diversion channel is driven by the switching motor to tilt to one side, blocking the other side of the channel. The material enters the unblocked channel and falls onto the loading tray below. Once the weighing sensor detects that the material has reached the preset weight, the switching motor quickly rotates, causing the rotating switching plate to rotate in the opposite direction, switching to the other side. This blocks the channel on the side that has reached the weighing standard and opens the channel on the other side. The material then falls onto the loading tray on the other side for weighing. At the same time, the side that has reached the weighing standard tilts the loading tray toward the discharge port via the hinged telescopic rod, emptying the material and then resetting it. At this point, the weighing on the other side is complete, and the rotating switching plate switches to the channel on the side that has completed weighing and blocks it. This cycle is repeated to achieve uninterrupted weighing and feeding.
