Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder processing engineering equipment technology, and in particular to a powder flow aid device. Background Technology
[0002] In the powder processing, the powder collected in the hopper needs to be discharged from the hopper in a timely or periodic manner before proceeding to the next step. Otherwise, it will affect the normal operation of the next process. During the powder feeding process, since the powder does not always move naturally and smoothly like a liquid, due to factors such as the friction, adhesion, static electricity between its particles and the structure of the hopper, the powder may experience bridging (forming an arch structure above the outlet), clumping, and rat holes (only the powder in the center flows, while the powder around it stops and moves through the central hole). These problems will lead to key points in the production process and incomplete unloading.
[0003] When the above-mentioned problems occur, manual intervention by staff is usually required, which involves frequent stirring or poking with a stirring rod to force the powder to resume its flow. However, this method is inefficient, labor-intensive, and has a harsh working environment, while also resulting in inconsistent processing effects. Therefore, in order to solve the above-mentioned technical problems, this application proposes a powder flow aid device. Utility Model Content
[0004] The purpose of this utility model is achieved through the following means: a powder flow aid device, comprising an upper hopper, a lower hopper, and a flow aid component. The lower hopper is disposed above the upper hopper, and the flow aid component is disposed in the middle of the hopper. The flow aid component includes a flow aid section, an activation rail, and a scraper. The flow aid section is rotatably disposed between the upper and lower hoppers. The scraper is evenly distributed on the inner circular surface of the flow aid section. A synchronous scraper block is detachably mounted on the upper end of the scraper. The lower end of the scraper extends toward the inner circular surface of the lower hopper. The side of the scraper away from the inner circular surface adopts an inclined surface structure. The activation rail is detachably disposed in the middle of the flow aid section.

[0012] For this embodiment, please refer to Figures 1-5 The specific implementation of this powder flow aid device includes an upper hopper 1, a lower hopper 2, and a flow aid assembly. The lower hopper 2 is positioned above the upper hopper 1. The flow aid assembly is installed in the middle of the hopper and includes a flow aid section 3, an activation barrier 4, and scrapers 5. The flow aid section 3 is rotatably positioned between the upper hopper 1 and the lower hopper 2. The scrapers 5 are evenly distributed on the inner circular surface of the flow aid section 3. A synchronous scraper block 6 is detachably installed at the upper end of the scraper 5. The lower end of the plate 5 extends toward the inner circular surface of the lower hopper 2. The side of the scraper 5 away from the inner circular surface adopts an inclined surface structure. The activation bar 4 is detachably set in the middle of the flow aid section 3. The edge of the activation bar 4 is provided with an inclined surface structure that matches the inclined surface of the scraper 5 near the scraper 5. The inclined surface of the synchronous scraper block 6 is provided with a pin hole 7 near the top surface of the activation bar 4. The pin hole 7 is detachably provided with a post 8. The lowest point of the post 8 is in contact with the upper top surface of the activation bar 4. Specifically, when the flow aid section 3 rotates, it drives the scraper 5, the synchronous scraper block 6, and the activation rail 4 to rotate synchronously. While rotating, the scraper 5 and the synchronous scraper 5 will scrape off the powder attached to the wall surface of the lower section 2 hopper and the upper section 1 hopper respectively, while the activation rail 4 will stir the powder in the middle area of the upper section hopper 1 to prevent the powder from having rat holes. When installing the activation bar 4, align the edge of the activation bar 4 with the scraper 5, and then press the activation bar 4 down toward the lower hopper 2. The inclined structure of the edge of the activation bar 4 cooperates with the inclined surface of the scraper 5 to achieve the stopping and limiting effect. At this time, the top surface of the activation bar 4 is aligned with the lowest point of the pin hole 7. Finally, insert the pin 8 into the pin hole 7. The lowest point of the pin 8 contacts the top surface of the activation bar 4 to achieve the limiting effect.
[0013] The top and bottom surfaces of the flow aid section 3 are provided with positioning rings 9. The upper hopper 1 and the bottom surface of the lower hopper 2 are provided with positioning ring grooves 10 that match the positioning rings 9. The positioning ring grooves 10 extend in a direction away from the flow aid section 3. The outer circumference of the flow aid section 3 is connected with a drive toothed ring 11. The lower end of the upper hopper 1 and the upper end of the lower hopper 2 are provided with connecting protrusions 12 near the drive toothed ring 11. The connecting protrusions 12 are integrally fixedly connected to each other by a connecting ring 22.
[0014] A drive assembly is provided on one side of the outer surface of the connecting ring 22. A connection notch 13 is provided near the drive assembly of the connecting ring 22. The connection notch 13 extends in the direction of the drive gear ring 11. The drive unit includes a drive motor 14 and a drive gear 15. The outer surface of the rotatable connecting block of the drive gear 15 is near the connection notch 13, and the drive gear 15 meshes with the drive gear ring 11. Specifically, when the drive motor 14 is turned on, the drive shaft of the drive motor 14 drives the drive gear 15 to rotate synchronously. The drive gear 15, based on its meshing relationship with the drive gear ring 11, drives the flow aid section 3 to rotate.
[0015] The outer side of the connecting ring 22 is fixedly provided with a mounting block 16 near the connecting notch 13. The drive gear 15 is rotatably provided inside the mounting block 16. The mounting block 16 is provided with a rotating cavity 17 that matches the drive gear 15. The rotating cavity 17 is in communication with the connecting notch 13. The drive motor 14 is located below the outer side of the mounting block 16. The drive shaft of the drive motor 14 passes through the mounting block 16 and is synchronously connected to the drive gear 15. The bottom surface of the drive motor 14 is provided with a support plate 18. A connecting plate 19 is provided on one side of the support plate 18.

The position of the synchronous scraper block 6 near the inner circular surface of the upper hopper 1 is in contact with the inner circular surface of the upper hopper 1.
[0017] The workflow of this application is as follows: When the drive motor 14 is turned on, the drive shaft of the drive motor 14 drives the drive gear 15 to rotate synchronously. The drive gear 15, based on its meshing relationship with the drive gear ring 11, drives the flow aid section 3 to rotate. When the flow aid section 3 rotates, it drives the scraper 5, the synchronous scraper block 6, and the activation bar 4 to rotate synchronously. At the same time, the scraper 5 and the synchronous scraper 5 will scrape off the powder attached to the wall surface of the lower hopper 2 and the upper hopper 1 respectively, while the activation bar 4 will stir the powder in the middle area of the upper hopper 1 to prevent the powder from forming a rat hole.
