Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides: a powder additive metering and dispensing device, including a mounting base 1, a hopper 3 connected to the top of the mounting base 1 via a bracket 2, a loosening and anti-clogging component inside the hopper 3, and a hopper cover 4 rotatably connected to the rotating shaft 6 of the loosening and anti-clogging component; a guide cylinder 9 installed below the discharge pipe of the hopper 3 on the surface of the mounting base 1, a spiral shaft 13 for assisting in the conveying of powder additives rotatably installed inside the guide cylinder 9, and a material frame 16 below the discharge port 11 of the guide cylinder 9; a mounting plate 14 installed on one side of the mounting base 1, the surface of the mounting plate 14 connected to both sides of the material frame 16 via a U-shaped electronic scale 15, and a feeding baffle 20 connected to the bottom of the material frame 16 via an adjusting component.

[0022] It is worth noting that, through the coordinated arrangement of structures such as the hopper 3, guide cylinder 9, mounting plate 14, U-shaped electronic scale 15, material frame 16, feeding anti-clogging component, and adjustment component, the powder additives can be quantitatively fed, ensuring precise control of the amount of powder additives during the feeding process, further improving the effect of addition, and ensuring product quality and efficiency.

[0023] Specifically, the loosening and anti-clogging component includes: a stirring rod 7 connected to the surface of the rotating shaft 6, and a spiral blade 8 connected to the bottom end of the rotating shaft 6. The top of the bin cover 4 is connected to a stirring motor 5, the output end of the stirring motor 5 is connected to the top end of the rotating shaft 6, the spiral blade 8 is installed inside the discharge pipe of the bin 3 through the rotating shaft 6, and the bin cover 4 is installed on the top of the bin 3.

[0024] The rotating shaft 6 is the structure for mounting the stirring rod 7 and the spiral blade 8, which facilitates the driving and control of the stirring motor 5 to drive the rotating shaft 6 to move the stirring rod 7 and the spiral blade 8, to stir and disperse the powdered additives, and to prevent blockage during conveying. The silo cover 4 is the structure for sealing the silo 3 and for mounting the stirring motor 5 and the rotating shaft 6.

[0025] A feed inlet 10 is provided on the top surface of the feed cylinder 9, and the inner wall of the feed inlet 10 is movably connected to the surface of the discharge pipe of the hopper 3. A drive motor 12 is connected to the end of the feed cylinder 9, and the output end of the drive motor 12 is connected to one end of the screw shaft 13. The discharge port 11 is located at the bottom of one end of the feed cylinder 9.

[0026] Among them, the feed inlet 10 is used to transport the additives in conjunction with the discharge pipe of the hopper 3, the guide cylinder 9 is a material guiding structure for transporting the additives, and the drive motor 12 is a structure for driving the screw shaft 13 to ensure the stable transport of powder additives.

[0027] A human-machine interface screen 17 is mounted on the surface of the material frame 16. The human-machine interface screen 17 is electrically connected to the U-shaped electronic scale 15. A bubble level 18 is installed above the human-machine interface screen 17 and is embedded in the surface of the material frame 16. The electric push rod 22 and the drive motor 12 are electrically connected to the human-machine interface screen 17.

[0028] Specifically, the bubble level 18 is used to monitor the position of the material frame 16 in real time. The human-machine interface screen 17 controls the structure of the U-shaped electronic scale 15, the drive motor 12, and the electric push rod 22. The human-machine interface screen 17 presets the weighing value of the U-shaped electronic scale 15. After the powder additive inside the material frame 16 reaches the preset value, the drive motor 12 stops, so that the screw shaft 13 stops conveying the powder additive, ensuring the accuracy of the powder additive measurement inside the material frame 16. The electric push rod 22 is then activated, so that the electric push rod 22 extends and pushes open the feeding baffle 20. The opening of the feeding baffle 20 allows the powder additive inside the material frame 16 to be fed.

[0029] The adjustment assembly includes: positioning shafts 19 symmetrically installed on the bottom of both sides of the material frame 16, and mounting rods 21 disposed on one side of the positioning shafts 19; wherein, the surfaces of the positioning shafts 19 are rotatably connected to both sides of the feeding baffle 20, and electric push rods 22 are movably mounted on the surface of the mounting rods 21. Connecting rods 23 are symmetrically installed on both sides of the feeding baffle 20, and the surfaces of the connecting rods 23 are movably connected to the extended ends of the electric push rods 22.

[0030] Furthermore, the positioning shaft 19 is a structure for installing and positioning the feeding baffle 20, the mounting rod 21 is a structure for installing the electric push rod 22, and the connecting rod 23 is a structure for connecting the electric push rod 22, so as to facilitate the opening and closing of the feeding baffle 20 by the electric push rod 22. In the open state, the powder additive can be added, and in the closed state, the powder additive is metered.

[0031] The rotating shaft 6 is driven by the stirring motor 5, which in turn causes the stirring rod 7 and the spiral blades 8 to agitate the powdered additives inside the hopper 3 and transport them into the feed cylinder 9 through the discharge pipe. This effectively prevents additive blockage and ensures stable conveying. The spiral shaft 13 is driven by the drive motor 12 to transport the powdered additives at a uniform speed inside the feed cylinder 9, ensuring that the frequency of the additives entering the material frame 16 from the discharge port 11 is the same. This allows the drive motor 12 to stop conveying the additives in a timely and accurate manner when the U-shaped electronic scale 15 detects that the additives in the material frame 16 have reached the predetermined weight, ensuring the accuracy of additive metering. Finally, the connecting rod 23 is pushed by the electric push rod 22, causing the feeding baffle 20 to rotate around the positioning shaft 19, opening the bottom of the material frame 16 for additive feeding, further improving the effect of additive feeding and ensuring product quality and production efficiency.

[0032] 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.
