At this time, the controller 411 will send a signal to control the cylinder 405 to start and control the induction door 305 to close, thereby stopping the transportation of the powder. The cylinder 405 starts to drive the push rod 406 to move. Since the bottom of the push plate 407 and the touch switch 412 are at the same horizontal plane, the push plate 407 can move under the action of the push rod 406 when the load-bearing plate 408 moves to the touch switch 412, thereby pushing out the powder on the load-bearing plate 408.

At the same time, when the push plate 407 moves, it will also drive the moving rod 413 to move. When the moving rod 413 moves, it will drive the rotating rod 416 to rotate and open the rotating door 418. When it continues to move, it will drive the rotating rod 416 and the connecting shaft 419 to slide in the first chute 414 and the second chute 415, so as to ensure that all the powder is transported out from the feeding pipe 403 for filling.
