Technical Field

[0001] This utility model relates to the field of diamond powder processing technology, specifically to an automatic powder feeding device for diamond powder abrasive. Background Technology

[0002] In the field of diamond powder processing technology, diamond powder, as an important abrasive, is widely used in various industrial processes such as cutting, grinding, and polishing. Its processing quality directly affects the performance and effectiveness of the final product. In the production process of diamond powder, the grinding stage is a crucial step, as it not only relates to production efficiency but also directly affects the uniformity and consistency of the diamond powder.

[0003] The existing automatic powder feeding device has an unreasonable screening mechanism design, low screening efficiency, easy screen blockage, and cannot effectively distinguish between qualified and unqualified diamond powder, resulting in uneven particle size distribution of the product. For the unqualified diamond powder screened out, the traditional device lacks an effective reprocessing mechanism, and usually needs to be manually removed for secondary processing, which increases the complexity and cost of the production process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic powder feeding device for diamond powder abrasive, which aims to solve the problem that the substandard diamond powder screened out in the existing technology lacks an effective reprocessing mechanism and usually needs to be manually removed for secondary processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic powder feeding device for diamond powder abrasive includes an operating cylinder. A cover plate is fixedly connected to the top of the operating cylinder, a connecting pipe is fixedly connected to the top of the cover plate, and a storage cylinder is fixedly connected to the top of the connecting pipe. The operating cylinder, the connecting pipe, and the storage cylinder are interconnected internally. A powder feeding channel is fixedly connected to the top of the storage cylinder, and a discharge pipe is fixedly connected to the bottom of the operating cylinder. A baffle is fixedly connected to the top of the inner side of the operating cylinder, and a funnel is fixedly connected to the bottom of the baffle. A first screening screen is fixedly connected inside the funnel, and an extension cylinder is fixedly connected to the bottom of the funnel. A shaft is rotatably connected inside the baffle, a scraper is fixedly connected to the top of the shaft, and a blade is fixedly connected to the middle of the shaft, inside the extension cylinder.

[0007] As a preferred embodiment of this utility model, a motor is fixedly connected to the top of the baffle, the output end of the motor is fixedly connected to the insertion shaft, and a guide tube is fixedly connected to the bottom of the extension tube.

[0008] As a preferred embodiment of this utility model, the guide tube is fixedly connected to the outside of the discharge pipe, the discharge pipe is designed with an inclined structure, the bottom of the discharge pipe is rotatably connected to a bottom column, and the top of the bottom column is designed with a conical structure.

Cylindrical rods are symmetrically fixedly connected to the outside of the bottom column, and scraper strips are fixedly connected to the ends of the two sets of cylindrical rods that are far apart from each other.

[0010] As a preferred embodiment of this utility model, a funnel is fixedly connected to the top of the inner side of the storage cylinder, a track is fixedly connected to the bottom of the inner side of the storage cylinder, and a flat plate is slidably connected inside the track.

[0011] As a preferred embodiment of this utility model, a hollow cylinder is fixedly connected inside the flat plate. The inner diameter of the hollow cylinder is larger than the bottom diameter of the sluice tube, and a bottom cover is rotatably connected to the bottom end of the hollow cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when the hollow cylinder is moved by the electric telescopic rod, the plate slides inside the track. When the plate slides, its top will block the bottom of the cylinder to prevent further material feeding. As the hollow cylinder leaves the support plate, the bottom cover loses its supporting force and will unfold directly. At this time, the diamond powder will fall directly into the inside of the connecting cylinder and then enter the inside of the operating cylinder to achieve quantitative feeding.

[0015] 2. In this utility model, diamond powder that meets the standard will fall directly through the gaps in the screening screen, while diamond powder that does not meet the standard will directly enter the interior of the extension cylinder. The blade will further grind the diamond powder that does not meet the standard. The diamond powder accumulated inside the guide cylinder will enter the interior of the discharge pipe and fall directly into the interior of the operating cylinder. Then, the scraper will rotate in a cycle to scrape the diamond powder adsorbed on the inner wall of the operating cylinder. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-7 This utility model provides a technical solution:

[0026] An automatic powder feeding device for diamond powder abrasive includes an operating cylinder 1. A cover plate is fixedly connected to the top of the operating cylinder 1, a connecting pipe 2 is fixedly connected to the top of the cover plate, and a storage cylinder 3 is fixedly connected to the top of the connecting pipe 2. The operating cylinder 1, the connecting pipe 2, and the storage cylinder 3 are internally interconnected. A powder feeding channel 4 is fixedly connected to the top of the storage cylinder 3, and a discharge pipe is fixedly connected to the bottom of the operating cylinder 1. A baffle is fixedly connected to the top of the inner side of the operating cylinder 1, and a funnel 5 is fixedly connected to the bottom of the baffle. A first screening screen is fixedly connected inside the funnel 5, and an extension cylinder 6 is fixedly connected to the bottom of the funnel 5. A insertion shaft 7 is rotatably connected inside the baffle, and a scraper 8 is fixedly connected to the top of the insertion shaft 7. A blade 9 is fixedly connected inside the extension cylinder 6 in the middle. When diamond powder is poured into the powder feeding channel 4, its inclined design and the influence of gravity cause the diamond powder to directly enter the storage cylinder 3 and then the operating cylinder 1. The funnel 5 catches the falling diamond powder. Through the design of the screening screen, diamond powder that meets the standard will fall directly from the gap, while diamond powder that does not meet the standard will directly enter the extension cylinder 6. Then, the insertion shaft 7 is rotated, which drives the blade 9 to rotate, further grinding the diamond powder that does not meet the standard. At the same time, the scraper 8 will repeatedly scrape the inner surface of the funnel 5 to accelerate the screening effect of the screening screen.

[0027] Furthermore, in this embodiment, a motor 10 is fixedly connected to the top of the baffle, and the output end of the motor 10 is fixedly connected to the insertion shaft 7. A guide cylinder 11 is fixedly connected to the bottom of the extension cylinder 6. By rotating the motor 10, its output end will drive the insertion shaft 7 to rotate, and after grinding, the diamond powder will fall directly into the interior of the guide cylinder 11.

[0028] Furthermore, in this embodiment, a discharge pipe 12 is fixedly connected to the outside of the guide cylinder 11. The discharge pipe 12 has an inclined structure design, and a bottom column 13 is rotatably connected to the bottom of the discharge pipe 12. The top of the bottom column 13 has a conical structure design. Due to the conical design of the top of the bottom column 13, the diamond powder accumulated inside the guide cylinder 11 will enter the interior of the discharge pipe 12. Its inclined design allows the ground diamond powder to fall directly into the interior of the operating cylinder 1.

[0029] Furthermore, in this embodiment, the insert shaft 7 extends to the top of the bottom column 13 and is fixedly connected to the bottom column 13. Cylindrical rings are symmetrically fixedly connected to the outside of the bottom column 13. Scraper strips 14 are fixedly connected to the ends of the two sets of cylindrical rings that are far apart. When the insert shaft 7 rotates, it drives the bottom column 13 to rotate. Then the scraper strips 14 rotate in a cycle to scrape the diamond powder adsorbed on the inner wall of the operating cylinder 1 to prevent it from accumulating on the inner wall of the operating cylinder 1. Finally, it is discharged through the discharge pipe.

[0030] Furthermore, in this embodiment, a funnel 15 is fixedly connected to the top of the inner side of the storage cylinder 3, and a track 16 is fixedly connected to the bottom of the inner side of the storage cylinder 3. A flat plate 17 is slidably connected inside the track 16. The diamond powder poured in through the powder filling channel 4 will fall directly into the inside of the funnel 15, and then push the flat plate 17. The flat plate 17 will make linear movements inside the track 16.

[0031] Furthermore, in this embodiment, a hollow cylinder 18 is fixedly connected inside the flat plate 17. The inner diameter of the hollow cylinder 18 is larger than the bottom diameter of the funnel cylinder 15. A bottom cover 19 is rotatably connected to the bottom end of the hollow cylinder 18. A support plate 20 is fixedly connected to the bottom of the track 16. The bottom cover 19 slides on the top of the support plate 20. A vertical plate is fixedly connected to the bottom right side of the track 16. An electric telescopic rod is fixedly connected between the vertical plate and the hollow cylinder 18. By pushing the electric telescopic rod, the output end of the electric telescopic rod will then move towards the hollow cylinder 18. When the hollow cylinder 18 is pushed, it will be directly connected to the inside of the sluice cylinder 15 when it is in the initial position. The diamond powder will fall directly into the inside of the hollow cylinder 18. When the electric telescopic rod pushes the hollow cylinder 18 to move, it will drive the plate 17 to slide inside the track 16. When the plate 17 slides, its top will block the bottom of the sluice cylinder 15 to prevent the material from continuing to be fed. As the hollow cylinder 18 leaves the support plate 20, the bottom cover 19 loses its lifting force and will unfold directly. At this time, the diamond powder will fall directly into the inside of the connecting pipe 2.

[0032] In this embodiment, the specific implementation scenario is as follows: Diamond powder is poured into the powder feeding channel 4. Due to its inclined design and the influence of gravity, it falls directly into the funnel cylinder 15. The hollow cylinder 18, in its initial position, is directly connected to the inside of the funnel cylinder 15. The diamond powder falls directly into the hollow cylinder 18. When the electric telescopic rod pushes the hollow cylinder 18, it causes the plate 17 to slide inside the track 16. During this sliding motion, the top of the plate 17 seals the bottom of the funnel cylinder 15, preventing further material feeding. As the hollow cylinder 18 leaves the support plate 20, the bottom cover 19 loses its supporting force and unfolds directly. At this time, the diamond powder falls directly into the connecting pipe 2 and then into the operating cylinder 1. The funnel 5 collects the falling diamond powder, and through the design of the screening screen... Diamond powder that meets the standard will fall directly from the gap, while diamond powder that does not meet the standard will directly enter the interior of the extension cylinder 6. Then, the insert shaft 7 is rotated, which in turn drives the blade 9 to rotate, further grinding the diamond powder that does not meet the standard. At the same time, the scraper 8 will repeatedly scrape the inner surface of the funnel 5 to accelerate the screening effect of the screening screen. Due to the conical design of the top of the bottom column 13, the diamond powder accumulated inside the guide cylinder 11 will enter the interior of the discharge pipe 12. Its inclined design allows the ground diamond powder to fall directly into the interior of the operating cylinder 1. When the insert shaft 7 rotates, it drives the bottom column 13 to rotate. Then, the scraper 14 rotates in a cycle to scrape the diamond powder adsorbed on the inner wall of the operating cylinder 1 to prevent it from accumulating on the inner wall of the operating cylinder 1. Finally, it is discharged through the discharge pipe.

[0033] 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.
