[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] Please see Figures 1-6 This utility model provides a technical solution: it includes a storage compartment 1, the top of which is fixedly connected to a shell 2, the top of which is provided with a mesh-like heat dissipation hole, a motor 4 fixedly connected to the inner wall of the shell 2, a transmission rod 5 fixedly connected to the output end of the motor 4, the bottom of the transmission rod 5 fixedly connected to a turntable 6, and a plurality of scrapers 7 fixedly connected to the outer wall of the turntable 6, the outer wall of the scrapers 7 being in contact with the inner wall of the 1.

[0028] When motor 4 is started, the output power of motor 4 drives transmission rod 5 to rotate. Since transmission rod 5 is fixedly connected to turntable 6, turntable 6 rotates synchronously with transmission rod 5, thereby driving scraper 7 installed on turntable 6 to move in a circle along the inner wall of storage bin 1. During this process, scraper 7 continuously scrapes away residual powder adhering to the inner wall of storage bin 1, effectively preventing the accumulation of powder residue.

[0029] Example 2

[0030] Based on Embodiment 1, the top of the storage chamber 1 is fixedly connected to the vacuum chamber 8. A feed inlet 9 is fixedly connected to the outer wall of the vacuum chamber 8. One end of the feed inlet 9 is fixedly connected to a hose 10, and the other end of the hose 10 is fixedly connected to a pipe opening 12. A valve 13 is fixedly installed in the middle of the pipe opening 12. Simultaneously, a fixing block 11 is fixedly connected to the outer wall of the storage chamber 1. When no feeding is required, the hose 10 is snapped into the inner wall of the fixing block 11. An air duct 14 is fixedly connected to the top of the vacuum chamber 8, and an air valve 28 is snapped into one end of the air duct 14. A filter screen 27 is snapped onto the inner wall of the air duct 14. A removable filter screen 27 is snapped onto the connection between the vacuum chamber 8 and the air duct 14. The filter screen 27 ensures that the powder will not enter the air duct 14 during the feeding process. The bottom end of the air duct 14 is fixedly connected to the outer shell 17. A motor 18 is fixedly connected to the outer wall of the outer shell 17. A fan blade is fixedly connected to the output end of the motor 18. A fixing block 19 is fixedly connected to the outer wall of the motor 18. A bracket 20 is fixedly connected to the bottom of the storage chamber 1 near the edge, and the fixing block 19 is fixedly connected to the outer wall of the bracket 20.

[0031] Remove the hose 10 from the fixing block 11, ensuring it remains intact. Then, align the nozzle 12 on the hose 10 with the powder to be fed. Next, start the motor 18. The motor 18 outputs power, driving the fan blades to rotate at high speed. The high-speed rotating fan blades create a negative pressure environment inside the vacuum chamber 8 and the air duct 14. Under this negative pressure, the powder is drawn into the hose 10 and transported along it to the vacuum chamber 8. Finally, the powder continues to be affected by the negative pressure inside the vacuum chamber 8 and falls into the storage chamber 1, thus completing the entire feeding process.

[0032] Example 3

[0033] Based on Embodiment 2, a connecting pipe 21 is fixedly connected to the bottom of the storage compartment 1. The bottom of the connecting pipe 21 is connected to the conveying pipe 22. An output port 23 is fixedly connected to one end of the conveying pipe 22. A housing 3 24 is fixedly connected to the outer wall of the conveying pipe 22. A plurality of heat dissipation holes are opened at one end of the housing 3 24. A motor 3 25 is fixedly connected to the inner wall of the housing 3 24. A gear 15 is fixedly connected to the output end of the motor 3 25. The outer wall of the gear 15 meshes with a gear 2 16. An auger 3 is slidably connected to the inner wall of the conveying pipe 22. A slot 26 is opened at one end of the auger 3. One end of the gear 2 16 is engaged with the inside of the slot 26.

[0034] The rotation speed of motor 3 25 is pre-adjusted according to the production efficiency requirements. After motor 3 25 is started, its output end drives gear 1 15 to rotate. Since gear 1 15 and gear 2 16 are meshed, gear 2 16 rotates synchronously with gear 1 15. Screw 3 is engaged with gear 2 16 through the end slot 26 and rotates synchronously under the drive of gear 2 16. During this process, the powder in storage bin 1 enters the conveying pipe 22 through the connecting pipe 21 and is moved upward along the inner wall of the conveying pipe 22 under the rotation of screw 3. Finally, it is accurately output from the output port 23 to realize the feeding operation. The feeding rate can be effectively controlled by adjusting the rotation speed of motor 3 25 to meet the needs of different production conditions.

[0035] In actual use, remove the hose 10 from the fixing block 11, align the nozzle 12 with the powder to be fed, start the motor 2 18, which drives the fan blades to rotate, creating a negative pressure in the vacuum chamber 8 and the air duct 14, causing the powder to be sucked into the hose 10, transported to the vacuum chamber 8, and then fall into the storage chamber 1. At the same time, adjust the speed of the motor 3 25 according to the production efficiency requirements and start it, which drives the gear 15 to rotate, and the gear 2 16 meshing with it rotates synchronously. The auger 3 rotates accordingly, and the powder in the storage chamber 1 enters the conveying pipe 22 through the connecting pipe 21. Under the action of the auger 3, it moves upward and is accurately output from the output port 23. Adjusting the speed of the motor 3 25 can control the feeding rate. After feeding and discharging are completed, start the motor 1 4, which drives the transmission rod 5 to rotate. Since the transmission rod 5 is fixedly connected to the turntable 6, the turntable 6 drives the scraper 7 to move circumferentially along the inner wall of the storage chamber 1 to scrape off residual powder and prevent accumulation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
