[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0035] like Figures 1 to 3As shown, a powder material feeding device 10 according to an embodiment of the present disclosure includes a pipe assembly 100, a push rod assembly 200, a vibration assembly 300 and a handle assembly 400. The pipe assembly 100 is provided with a feeding channel 101 and a through hole 102. The through hole 102 is connected to the feeding channel 101, and the powder material falls in the feeding channel 101.

[0036] Furthermore, the push rod assembly 200 includes an agitator 210, an elastic push rod 220, a disc cam 230, a rotating shaft 240, a fixing plate 250, a push plate 260 and a support plate 270. The agitator 210 is arranged in the unloading channel 101, the elastic push rod 220 is penetrated in the through hole 102, one end of the elastic push rod 220 is connected to the agitator 210, the other end of the elastic push rod 220 is connected to the push plate 260, and the support plate 270 is connected to the pipeline assembly 100. One end of the push plate 260 abuts against the support plate 270, and the support plate 270 can support the push plate 260 so that the push plate 260 can extend along a direction parallel to the support plate 270. The plurality of fixing plates 250 are connected to the outer wall of the pipe assembly 100, and the push plate 260 is arranged between the two fixing plates 250. The push plate 260 can slide between the two fixing plates 250. The two fixing plates 250 are respectively provided with a mounting hole 2501. The disc cam 230 is sleeved on the rotating shaft 240. The disc cam 230 rotates with the rotating shaft 240. The disc cam 230 abuts against the push plate 260. Both ends of the rotating shaft 240 are passed through the mounting holes 2501.

[0037] In this embodiment, the operator rotates the handle assembly 400 to drive the disc cam 230 to rotate with the rotating shaft 240 as the fixed axis. The contour radius of the disc cam 230 changes with the rotation, and the distance between the push plate 260 abutted by the disc cam 230 and the rotating shaft 240 changes, so that the push plate 260 reciprocates, and the push plate 260 pushes the elastic push rod 220 and the stirring member 210 to reciprocate in turn. When the stirring member 210 moves, it continuously stirs the powder in the feeding channel 101, so that the powder in the feeding channel 101 falls quickly; when the vibration assembly 300 is working, it continuously vibrates the pipeline assembly 100, so that the powder adhering to the inner wall of the pipeline assembly 100 is impacted and falls off, and the powder in the feeding channel 101 is impacted by the vibration, so that the falling speed of the powder is accelerated.

[0038] The above-mentioned powder feeding device 10 rotates the disc cam 230, so that the push plate 260 abutted by the disc cam 230 performs reciprocating motion, and the push plate 260 pushes the elastic push rod 220 and the stirring member 210 to perform reciprocating motion in turn, so that the stirring member 210 continuously stirs the powder in the feeding channel 101 during the reciprocating motion, dredges the powder in the feeding channel 101, and avoids the clogging of the feeding channel 101. The powder feeding device 10 does not need to stop production when dredging, thereby improving production efficiency; the vibration component 300 continuously vibrates the pipeline component 100, so that the powder in the pipeline component 100 is continuously vibrated, and the powder adhering to the inner wall of the pipeline component 100 falls off. When the pipeline component 100 vibrates, the fluidity of the powder is increased, and the falling speed of the powder is further accelerated.

In this embodiment, the elastic sleeve 222 deforms when compressed, and thrust is generated at both ends of the elastic sleeve 222, so that the push plate 260 abutted by the elastic sleeve 222 is reset, thereby driving the connecting rod 221 to reset the stirring member 210, and then the push plate 260 abutted by the disc cam 230 completes reciprocating motion.

In this embodiment, the tip of the spike member 520 is arranged to face upward, and when a large piece of powder falls through the push rod assembly 200, the large piece of powder that hits the tip of the spike member 520 is dispersed, so that the fluidity of the powder is increased, and the large piece of material is prevented from blocking the feeding channel 101.

[0045] like Figure 2 As shown, in one embodiment, the handle assembly 400 includes a sleeve 410, a connecting plate 420 and a handle 430. The sleeve 410 is connected to one end of the rotating shaft 240, one end of the connecting plate 420 is connected to the sleeve 410, and the handle 430 is connected to the other end of the connecting plate 420. The handle 430 is located on the side of the connecting plate 420 away from the sleeve 410. In this embodiment, the handle 430 drives the sleeve 410 of the connecting plate 420 to rotate, and the sleeve 410 drives the push rod assembly 200 to continuously stir the powder in the feeding channel 101. By extending the connecting plate 420, the operator can hold the handle 430 and rotate it with less effort.

[0046] like Figure 1 and Figure 2As shown, in one embodiment, the pipeline assembly 100 includes a first half pipe 110, a second half pipe 120 and a fixing member 130.
