The invention provides a feeding device. The feeding device comprises a feeding inlet, a stirring cavity and a feeding cavity, wherein the stirring cavity is arranged between the feeding inlet and the feeding cavity; a feeding
threaded rod penetrates through the feeding cavity; an arc breaking elastic piece is arranged in the stirring cavity, one end of the arc breaking elastic piece is fixedly installed in the combination position of the stirring cavity and the feeding inlet, and the other end of the arc breaking elastic piece is suspended; a stirring mechanism matched with the arc breaking elastic piece is further arranged in the stirring cavity and comprises a rotary shaft and a stirring
paddle; in the rotation process of the stirring mechanism, the stirring
paddle periodically makes contact with the arc breaking elastic piece, and the
contact position of the arc breaking elastic piece deforms elastically, so that the suspended end of the arc breaking elastic piece is driven to swing, and arc breaking is carried out on materials; when the stirring
paddle and the arc breaking elastic piece are separated, the arc breaking elastic piece recovers the
natural state. According to the feeding device, the arc breaking elastic piece is triggered by the stirring mechanism to swing vertically, arc breaking is carried out on the materials within a
large range, the effect that the feeding
threaded rod receives materials uniformly is guaranteed, and the discharging precision is effectively improved.
