[0021] Please refer to Figures 1 to 3 , a powder feeding mechanism comprises a servo motor 1, a material box 2, a groove roller 3, a feed chute 4, a material baffle plate 5 and a scraper assembly 7. The material box 2 is fixedly installed above the feed chute 4 and is connected to the feed chute 4. The material box 2 is used to store powder; the groove roller 3 is rotatably installed in the feed chute 4, the servo motor 1 is arranged at one end of the groove roller 3, and the main shaft of the servo motor is connected to the groove roller 3 through a coupling, and the main shaft of the servo motor 1 drives the groove roller 3 to rotate when the main shaft rotates, and the weight of each powder falling is controlled by controlling the rotation speed of the groove roller 3; the material baffle plate 5 is slidably connected to the lower port of the feed chute 4, and the material baffle plate 5 is used to limit the falling range of the powder to prevent the powder from splashing everywhere; the scraper assembly 7 is arranged on both sides of the feed chute 4, and the scraper assembly 7 is used to scrape out the excess material on the side of the feed chute 4 to ensure that the powder discharged each time just fills the groove.

[0022] Furthermore, an opening is provided at one end of the material box 2, and a baffle 21 is provided at the opening. The baffle 21 is fixedly mounted on the material box 2, and the baffle 21 is an acrylic plate. Since the acrylic plate is transparent, the operator can observe the flow of the powder inside the material box 2 from the baffle 21, which is convenient for timely adding the powder. In addition, the surface of the acrylic plate is smooth and not easy to absorb impurities and dirt, which can avoid contamination of the powder and ensure the quality of the powder.

[0023] Furthermore, the feeding mechanism also includes a support frame 6, and the material box 2 is fixedly mounted on the support frame 6, so that the material box 2 can bear the weight of the powder and maintain balance, prevent the material box 2 from loosening or falling off during the feeding process, and ensure that the powder can be accurately fed. The servo motor 1 is provided with a motor mounting seat 11, and the servo motor 1 is fixed to the other end of the support frame 6 through the motor mounting seat 11.
