Description

Technical Field

[0001] This application relates to the field of powder feeding technology, and in particular to a precision metering device for powder feeding. Background Technology

[0002] Powder feeding refers to the process of transporting powdery substances (such as powders, granules, etc.) from one place to another. This is a common operation in many industrial applications, especially in industries such as chemical, metallurgical, food processing, and pharmaceutical.

[0003] Referring to patent publication number CN210135986U, a precision powder feeding and metering device utilizes a control device designed with predetermined material feeding weight control parameters to drive a feeding device, feeding powder from a storage unit to the outlet of a feeding pipe unit. Simultaneously, a material feeding control device moves a plug that is pressed against the outlet to a predetermined opening, allowing powder to fall into a metering unit. This opening can be finely adjusted to a gap size to precisely control the minute amount of powder falling from the outlet. The powder is fed into the metering unit according to the target weight parameters set by the control device. The reading from the metering unit is fed back to the control device to verify whether the target weight has been achieved. In this way, ultra-precise metering effect can be obtained when feeding powder.

[0004] While the above solution can measure powder, it still has some shortcomings in actual use. For example, although it can accurately measure powder through the load-bearing device, it is not easy to automatically discharge the powder after it is loaded, which requires manual handling and affects the feeding efficiency.

[0005] Therefore, we propose a precision metering device for powder feeding to solve the above problems. Utility Model Content

[0024] A fixing seat 10 is fixedly installed on the right side of the bracket 5. The bottom surface of the fixing seat 10 is fixedly installed on the upper surface of the U-shaped plate 4. The fixing seat 10 can reinforce the bracket 5 and prevent the bracket 5 from becoming loose. A first servo motor 6 is fixedly installed on the inner top wall of the bracket 5. A spiral conveying shaft 8 is fixedly installed on the output end of the first servo motor 6. A conical cylinder 7 is fixedly installed on the upper surface of the U-shaped plate 4. A connecting ring 11 is fixedly installed on the outer surface of the conical cylinder 7.

The connecting ring 11 can reinforce the conical cylinder 7 and prevent the conical cylinder 7 from becoming loose. A conical cover 9 is provided above the U-shaped plate 4.

[0025] The bottom surface of the conical cover 9 is fixedly installed on the upper surface of the conical cylinder 7. The conical cover 9 can guide the raw material, making it easier for the raw material to enter the interior of the conical cylinder 7. The inner wall of the cylinder 1 is connected to two rotating shafts 15. The right end of the connecting shaft 15 is fixedly installed with a first gear 13. The right side of the cylinder 1 is fixedly installed with a connecting frame 12. The left side of the connecting frame 12 is fixedly installed with a second servo motor 16. The output end of the second servo motor 16 is fixedly installed with a rotating shaft 17. The output end of the rotating shaft 17 is fixedly installed with a second gear 18.

[0027] The working principle of this application is:

[0028] In use, the powder is first poured into the conical shroud 9, which guides the powder into the conical cylinder 7. Then, the first servo motor 6 is started, which drives the screw conveyor shaft 8 to rotate. During the rotation of the screw conveyor shaft 8, the powder is discharged downwards and falls into the collection box 14. At the same time, the pressure sensor 20 supports the collection box 14 and displays the weight through the control panel 2. When the weight inside the collection box 14 reaches the set value, the first servo motor 6 is stopped, and the second servo motor 16 is moved, which drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the second gear 18, which in turn drives the first gear 13 to rotate. The first gear 13 drives the connecting shaft 15 to rotate, which in turn drives the connecting seat 19 and the collection box 14 to rotate. During the rotation of the collection box 14, the powder can be discharged, allowing it to fall downwards and thus feeding the powder.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
