[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] like Figure 1 to Figure 3 As shown, Example 1, a powder material discharge device, includes a scraper mechanism 1, a material bin 2 and a discharge pipe 3 connected to the bottom of the material bin 2; the scraper mechanism 1 includes a scraper plate 11, a connecting ring 12 and a driving component 13, the connecting ring 12 is arranged in the docking gap between the material bin 2 and the discharge pipe 3, the inner ring of the connecting ring 12 is connected with the scraper plate 11, and the driving component 13 drives the connecting ring 12 to drive the scraper plate 11 to rotate against the inner wall of the discharge pipe 3.

[0019] By setting the scraper plate 11 inside the discharge tube 3 and the driving component 13 outside, the scraper plate 11 and the driving component 13 are connected by a connecting ring 12. The connecting ring 12 not only plays a sealing role, but also can achieve the purpose of driving the scraper plate 11 to rotate and scrape the material. In this discharge device, only the scraper plate 11 is set inside the discharge tube 3, which reduces the mechanical structure inside the discharge tube 3 and avoids excessive mechanical structures causing unsmooth discharge.

[0020] In a specific implementation, scraper plates 11 are provided at both the upper and lower ends of the connecting ring 12 to clear the blockage of the material bin 2 and the discharge pipe 3 at the same time.
