[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1-7This utility model provides an embodiment of a powder dispersion and feeding system, comprising a base 1 and a housing 2. The housing 2 is mounted on the top of the base 1, and a collection box 8 is disposed on the outside of the base 1. Two sets of stirring tanks 7 are disposed on the outside of the base 1 away from the collection box 8. A first discharge hood 3 is mounted on the bottom of the housing 2, extending into the interior of the housing 2. A second discharge hood 4 is mounted on the bottom of the housing 2 away from the first discharge hood 3. A filter screen 25 is mounted on the top of the second discharge hood 4, and a protective cover 6 is mounted on the top of the filter screen 25. The second discharge hood 4 on one side of the filter screen 25... A third discharge hood 5 is installed on the wall. A first screw rod 12 is movably installed inside the housing 2. One end of the first screw rod 12 extends to the outside of the housing 2, and a rotating shaft 11 is installed at the other end of the first screw rod 12. Multiple stepper motors 13 are installed inside the housing 2 below the first screw rod 12. A rotating shaft 14 is installed at the output end of each stepper motor 13. The rotating shaft 14 is movably connected to the housing 2. An inclined plate 26 is installed inside the housing 2 below the rotating shaft 14. A vibration motor 24 is installed on the outer wall of the inclined plate 26. A servo motor 9 is installed at the top of the base 1 below the rotating shaft 11.

[0028] A synchronous belt pulley assembly 10 is installed at the output end of the servo motor 9, and the end of the synchronous belt pulley assembly 10 away from the servo motor 9 is connected to the rotating shaft 11;

[0029] When using the powder dispersion and feeding system, the powder is poured into the housing 2. The servo motor 9 is turned on, and supported by the base 1, it drives the synchronous pulley assembly 10 to rotate. The synchronous pulley assembly 10 drives the rotating shaft 11 to rotate, which in turn drives the first screw rod 12 to rotate. The first screw rod 12 conveys the powder towards the discharge port. During this conveying process, the powder passes over the surface of the rotating shaft 14. Multiple stepper motors 13 are then turned on, and supported by the housing 2, they drive the rotating shaft 14 to rotate, causing the fine powder to fall downwards through the gaps between the rotating shafts 14 onto the surface of the inclined plate 26. Finally, the vibration motor 24 is turned on, and supported by the housing 2, it drives... The inclined plate 26 vibrates, causing the fine powder on its surface to fall through the first discharge hood 3 into the interior of a set of feed hoods 16. The powder remaining inside the first screw rod 12 continues to be conveyed to the discharge port and falls onto the surface of the second discharge hood 4 for further screening through the filter screen 25. This allows the fine powder to fall through the filter screen 25 and the second discharge hood 4 into the interior of another set of feed hoods 16, while the large powder particles fall through the third discharge hood 5 into the collection box 8 for collection. This facilitates multi-stage screening of powder, enabling the dispersion feeding system to conveniently distinguish the particle size of powder through multi-stage screening. It also facilitates the sequential discharge of powders of different particle sizes, improving the accuracy of the dispersion feeding system in screening and dispersing powders of different particle sizes.

[0030] The top of the base 1 below the first discharge hood 3 and the second discharge hood 4 are both equipped with a feed hood 16, and the bottom of the feed hood 16 is equipped with a hollow cylinder 17.

[0031] The end of the hollow cylinder 17 away from the feed hood 16 extends into the interior of the mixing tank 7. A power motor 15 is installed at one end of the hollow cylinder 17. A second spiral rod 18 is installed at the output end of the power motor 15. The second spiral rod 18 extends into the interior of the hollow cylinder 17 and is movably connected to the hollow cylinder 17.

[0032] A variable frequency motor 19 is installed at the top of each mixing tank 7. A stirring rod 20 is installed at the output end of each variable frequency motor 19. The stirring rod 20 extends into the interior of the mixing tank 7 and is movably connected to the mixing tank 7. Stirring blades 21 are fitted on the surface of the stirring rod 20 inside the mixing tank 7.

[0033] An air inlet pipe 22 is installed on one side of the mixing tank 7, and a discharge pipe 23 is installed on the other side of the mixing tank 7.

[0034] When further dispersion of the powder is required, the two sets of power motors 15 are turned on. Supported by the base 1, the power motors 15 drive the second spiral rod 18 to rotate inside the hollow cylinder 17. The second spiral rod 18 drives the powder inside the feed hood 16 to be conveyed to the inside of the mixing tank 7. The air inlet pipe 22 is turned on to allow high-pressure airflow to enter the mixing tank 7 for purging. The frequency converter motor 19 is turned on. Supported by the mixing tank 7, the frequency converter motor 19 drives the stirring rod 20 to rotate. The stirring rod 20 drives the stirring blade 21 to rotate. The airflow disperses the powder, and the stirring blade 21 stirs the powder, making the powder more evenly dispersed. The powder is discharged through the discharge pipe 23. This system enables convenient dispersion and discharge of powders of different particle sizes, increases the types of powder dispersion, and improves the efficiency of powder dispersion.

[0035] Working Principle: When using the powder dispersion and feeding system, powder is poured into the housing 2. The servo motor 9 drives the synchronous belt pulley assembly 10 to rotate, which in turn drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the first screw rod 12 to rotate, which in turn conveys the powder towards the discharge port. During the conveying process, the powder passes over the surface of the rotating shaft 14. The stepper motor 13 drives the rotating shaft 14 to rotate, causing the fine powder to fall downwards through the gaps between the rotating shafts 14 onto the surface of the inclined plate 26. The vibration motor 24 drives the inclined plate 26 to vibrate, causing the fine powder on the surface of the inclined plate 26 to fall through the first discharge hood 3 into the interior of a set of feed hoods 16. The powder remaining inside the first screw rod 12 continues to be conveyed towards the discharge port, falling onto the surface of the second discharge hood 4 and being filtered again by the filter screen 25. The first screening process allows fine powder to pass through the filter screen 25 and the second discharge hood 4, falling into the interior of another set of feed hoods 16. Larger powder particles fall into the collection box 8 through the third discharge hood 5 for collection, facilitating multi-stage powder screening. When further dispersion of the powder is required, the power motor 15 drives the second screw rod 18 to rotate inside the hollow cylinder 17. The second screw rod 18 carries the powder inside the feed hood 16 to the interior of the mixing tank 7. The air inlet pipe 22 is opened to allow high-pressure airflow to enter the mixing tank 7 for purging. The frequency converter motor 19 drives the stirring rod 20 to rotate, which in turn drives the stirring blades 21 to rotate. The airflow disperses the powder, and the stirring blades 21 stir the powder, making the powder more evenly dispersed. The powder is then discharged through the discharge pipe 23, completing the operation of the dispersion and powder feeding system.
