[0030] See also Figures 1 to 6 The present invention discloses a powder feeding device, which includes: a material container 1, a stirring driving member 2, a stirring structure 3 and a feeding structure 4;

[0031] The material container 1 includes a material storage barrel 11 and a mixing tank 12 connected to each other. The mixing drive 2 is provided at one end of the material storage barrel 11. The mixing tank 12 is provided with a discharge port. The mixing drive 2 extends into the mixing tank 12 and is connected to the mixing structure 3 to drive the mixing structure 3 to rotate.

[0032] The stirring structure 3 includes a stirring rod 31 and a stirring blade 32. One end of the stirring rod 31 is connected to the stirring drive member 2, and the other end of the stirring rod 31 is connected to the stirring blade 32.

[0033] One end of the stirring blade 32 is located in the stirring tank 12 and is provided with a first inclined blade 321. The other end of the stirring blade 32 is located in the discharge port and is provided with a second inclined blade 322. The outer wall inclination angle of the first inclined blade 321 is the same as the inner wall inclination angle of the stirring tank 12. The inner wall inclination angle of the second inclined blade 322 is the same as the inner wall inclination angle of the discharge port. The first inclined blade 321 and the second inclined blade 322 are both eight-shaped structures, and the two eight-shaped structures are arranged in opposite directions.

[0034] Specifically, a cover plate 13 is provided at one end of the material holding barrel 11, and the stirring drive member 2 is mounted on the cover plate 13. The material holding barrel 11 is clamped between the cover plate 13 and the mixing tank 12 and connected by fasteners. A feed pipe 6 is provided on the cover plate 13 for feeding. Optionally, in this embodiment, the fastener is a long screw 14. Preferably, the material holding barrel 11 is engaged with the inner hole of the cover plate 13 and is sealed by a gasket 15. The sealing connection is achieved by the gasket 15. Optionally, the gasket 15 can be made of an elastic material such as a rubber material. A flange plate 121 is provided at the end of the mixing tank 12. The flange plate 121 is arranged parallel to the cover plate 13. The material holding barrel 11 is engaged with the inner hole of the flange plate 121 and is sealed by a gasket 15. The two ends of the long screw 14 are respectively mounted on the cover plate 13 and the flange plate 121. Furthermore, a bent mounting plate 122 is provided on the outer side of the flange plate 121 for mounting the entire material container 1 on an external structure such as a wall to secure the entire material container 1 .

[0035] Preferably, in this embodiment, the material storage barrel 11 is made of a transparent material, and a material level meter 5 is installed on the outside of the material storage barrel 11. The material level meter 5 is fastened to the outer wall of the transparent material storage barrel 11 by screws or other structures. It senses the position of the powder in the barrel. If the level falls below a set value, it sends a signal to the feed pipe 6 to start feeding, effectively implementing the requirements of the automatic feeding process. Of course, the material storage barrel 11 can also be made of an opaque material, and the material level meter 5 only needs to be installed inside the material storage barrel 11. The material level meter 5 is electrically connected to an external processor to realize signal transmission and automated feeding.

[0036] Furthermore, the mixing tank 12 is provided with a compressed air inlet, through which compressed air is introduced as needed to prevent the powder from becoming compacted.

[0037] Optionally, the stirring drive component 2 is a motor, which is installed on the cover 13. The motor is vertically installed on the cover 13 by bolts and other structures, and the shaft of the motor extends into the material bucket 11. Optionally, the output shaft of the motor is directly connected to the stirring rod 31 through a sleeve with a keyway inside, and is fastened by screws. The stirring rod 31 and the stirring blade 32 are fastened with screws and other structures.

[0038] The material discharge structure 4 includes a receiving bowl 41, a docking circular pad 42 and a powder dropping pipe 43. A coarse adjustment disk 7 is provided at the material discharge port. The coarse adjustment disk 7 is threadedly connected to the material discharge port and can be adjusted. The receiving bowl 41 is provided corresponding to the coarse adjustment disk 7. The docking circular pad 42 is provided in the receiving bowl 41 and connected to the powder dropping pipe 43. One end of the powder dropping pipe 43 is provided in the receiving bowl 41, and the other end of the powder dropping pipe 43 extends out of the receiving bowl 41 for dropping materials.

[0039] By rotating the coarse adjustment disk 7, the gap h between the coarse adjustment disk 7 and the docking circular pad 42 can be adjusted to achieve coarse adjustment of powder feeding. Figure 4 As shown, it is actually the relative distance between the lower end surface of the coarse adjustment disk 7 and the upper end surface of the docking circular pad 42 in the axial direction.

[0040] Specifically, the receiving bowl 41 is arranged at the discharge port and does not need to be connected to the structure of the mixing tank 12. In fact, when in use, the entire material container 1 is arranged in the up and down directions, and the receiving bowl 41 can be arranged below the material container 1. The powder drop pipe 43 is threadedly connected to the receiving bowl 41. The outer side surface of the powder drop pipe 43 located in the receiving bowl 41 is provided with a plurality of through holes 431. The powder in the receiving bowl 41 enters the powder drop pipe 43 through the through holes 431. One end of the powder drop pipe 43 has an end plate 432, and the end plate 432 is connected to the docking circular pad 42 by a structure such as screws. The docking circular pad 42 is suspended in the receiving bowl 41.

[0041] Optionally, in this embodiment, an adapter 8 is provided at the discharge port, and the coarse adjustment disk 7 is threadedly connected to the adapter 8 .

[0042] Furthermore, the material discharge structure 4 further includes a vibration mechanism 44 , which is arranged outside the powder discharge pipe 43 . The frequency of the vibration mechanism 44 is adjustable, which can be used to fine-tune the powder discharge.

[0043] Vibration mechanism 44 includes a vibration bracket 441 and a vibrating electromagnet 442. Bracket 441 is mounted on powder drop tube 43 and locked with a locking member. Vibrating electromagnet 442 is mounted on bracket 441. Optionally, bracket 441 includes a sleeve and an extension rod. The sleeve fits over powder drop tube 43, with one end of the extension rod connected to the sleeve and the other end to the vibrating electromagnet 442. The vibration frequency of vibrating electromagnet 442 allows precise adjustment of the powder discharge size, enabling fine adjustment of the discharge.

[0044] The present invention provides a powder feeding device, in which the stirring blades 32 are arranged in an eight-shaped structure with two opposite directions, wherein the outer wall inclination angle of the first inclined blade 321 is the same as the inner wall inclination angle of the stirring tank 12, and the inner wall inclination angle of the second inclined blade 322 is the same as the inner wall inclination angle of the discharge port, so that the stirring blade 32 can be precisely matched with the tank body of the stirring tank 12 to achieve the purpose of uniform stirring and uniform feeding. By rotating the coarse adjustment disk 7, the gap between the coarse adjustment disk 7 and the docking circular pad 42 can be adjusted to achieve coarse adjustment of powder feeding. The adjustable frequency setting of the vibration mechanism 44 can play a role in fine adjustment of powder feeding. The setting of the compressed air inlet can allow compressed air to be introduced according to demand to prevent the powder from compacting.
