in the utility model discloses a powder discharge structure 100, powder discharge structure 100 includes first feeding shell 110 and second feeding shell 120, first feeding shell 110 has feed inlet 112 and first feeding channel 111 that communicates with feed inlet 112, second feeding shell 120 has discharge gate 124 and second feeding channel 121 that communicates with discharge gate 124, at least part of second feeding channel 121 communicates with first feeding channel 111 to form the feeding channel of powder; the powder discharging structure 100 further comprises a first stirring shaft 130 and a feeding shaft 140, the first stirring shaft 130 is rotatably disposed in the first feeding channel 111, a stirring assembly 150 is disposed on the first stirring shaft 130, so that powder in the first feeding channel 111 enters the second feeding channel 121 under the action of the stirring assembly 150, and the feeding shaft 140 is rotatably disposed in the second feeding channel 121, so that powder in the second feeding channel 121 is discharged from the discharge port 124 under the action of the feeding shaft 140.

In a specific implementation process, the stirring assembly 150 includes a plurality of stirring blades 151 arranged at intervals, and each stirring blade 151 is arranged obliquely with respect to a horizontal plane, so that each stirring blade 151 can provide a relatively constant driving force for the powder when rotating at a constant speed, so as to drive the powder to uniformly enter the second feeding channel 121, and further, the powder uniformly entering the second feeding channel 121 can be uniformly discharged from the discharge port 124; moreover, under the action of the constant thrust of each stirring blade 151, the powder in the first feeding channel 111 can be compressed to a certain degree to reduce gaps between powder particles and bubbles between powder, so that the gaps between powder are uniform and constant, so that the powder in the first feeding channel 111 can uniformly and constantly enter the second feeding channel 121, the powder uniformly and constantly entering the second feeding channel 121 is uniformly and constantly discharged from the discharge port 124, and the discharge amount of the powder discharged from the discharge port 124 is uniform and constant, so that the control of the discharge amount of the powder is realized. Therefore, by using the powder discharging structure 100, a metering device can be omitted, and the overall structure of the discharging device with the powder discharging structure 100 is simplified, so that the problem that the overall structure of the discharging device is complex due to the arrangement of a weight sensor or a weight weighing device in the prior art is solved.

In addition, since the plurality of stirring blades 151 are arranged at intervals, a gap is formed between each two adjacent stirring blades 151, so that when the stirring blades 151 stir the powder, the gap is used for the powder to pass through, thereby avoiding the powder from being blocked and avoiding the powder in the second feeding housing 120 from being compacted. Because the powder discharging structure 100 can omit a metering device, the production cost is reduced.
