Description

Technical Field

[0001] This application relates to the field of powder feeding technology, and in particular to a powder arch-breaking and feeding device. Background Technology

[0002] Powder feeding typically refers to the process of conveying powdered raw materials into the production system through certain equipment or technical means for subsequent processing. Powder feeding is used in many industries, such as pharmaceuticals, food processing, chemical industry, and materials science. During the powder feeding process, powder often arches, leading to blockage.

[0003] Currently, an arch-breaking feeding device is needed when adding powder to assist in powder feeding. However, although the current arch-breaking feeding device can assist in powder feeding, it still has some shortcomings in actual use. For example, it is difficult to scrape the material adhering to the inner wall of the hopper, resulting in powder residue.

[0004] Therefore, we propose a powder arch-breaking and feeding device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a powder arch-breaking and feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A powder arch-breaking and feeding device includes a feeding hopper body. A feed pipe is fixedly connected to the left side of the feeding hopper body. A motor is fixedly installed on the upper surface of the feeding hopper body. A rotating shaft is fixedly installed at the output end of the motor. A conical spiral blade is fixedly installed on the outer surface of the rotating shaft. A connecting plate is fixedly installed on the outer surface of the rotating shaft. A set of top blocks arranged in a ring at equal intervals are fixedly installed on the outer surface of the connecting plate. Two spring-loaded flaps are fixedly installed on the inner wall of the feeding hopper body. A set of scrapers arranged in a ring at equal intervals is fixedly installed on the outer surface of the rotating shaft. The side of each scraper away from the rotating shaft is in contact with the inner wall of the feeding hopper body. A set of arc-shaped rods is provided inside the feeding hopper body. The top end of each arc-shaped rod is fixedly installed to the bottom end of the rotating shaft.

[0008] In a further embodiment, a conical cover is fixedly installed at the left end of the feed pipe, and a sealing cap is rotatably installed on the outer surface of the conical cover via a pin.

[0009] In a further embodiment, a set of support legs arranged in a ring at equal intervals are fixedly installed on the outer surface of the feeding hopper body, and two mounting holes are opened on the upper surface of each support leg.

[0010] In a further embodiment, a set of openings is provided on the upper surface of the conical spiral blade, and a warning strip is fixedly installed on the outer surface of the feeding hopper body.

[0011] In a further embodiment, a support ring is fitted onto the outer surface of the rotating shaft, and the bottom surface of each scraper is fixedly installed to the upper surface of the support ring.

[0012] In a further embodiment, a fixing seat is fixedly installed on the outer surface of the rotating shaft, and the bottom surface of the fixing seat is fixedly installed on the upper surface of the connecting plate.

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

[0014] This application, through the combination of a motor, a sluice gate, conical spiral blades, and a rotating shaft, enables the conical spiral blades to agitate the powder inside the hopper body. The sluice gate promotes powder flow, while the arc-shaped rod pushes the powder at the bottom of the hopper body during shaft rotation, preventing arching. Furthermore, the combination of a connecting plate, a top block, and a spring-loaded paddle causes the spring-loaded paddle to vibrate, thus causing the hopper body to vibrate and allowing the powder on the inner wall of the hopper body to flow downwards. Simultaneously, the scraper cleans the inner wall of the hopper body, effectively preventing powder residue inside the hopper body. Attached Figure Description

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.

[0022] Please see Figure 1-4 In this utility model, the powder arch-breaking and feeding device includes a feeding hopper body 1. A set of support legs 7 arranged in a ring at equal intervals are fixedly installed on the outer surface of the feeding hopper body 1. Each support leg 7 has two mounting holes 8 on its upper surface. The device can be fixed through the support legs 7 and the mounting holes 8 to prevent the device from becoming loose. A feed pipe 3 is fixedly connected to the left side of the feeding hopper body 1. A conical cover 4 is fixedly installed at the left end of the feed pipe 3. A sealing cover 5 is rotatably installed on the outer surface of the conical cover 4 through a pin. Powder can be easily added through the conical cover 4, and the sealing cover 5 can prevent foreign objects from entering the interior of the feeding hopper body 1.

[0023] A motor 2 is fixedly installed on the upper surface of the feeding hopper body 1. A rotating shaft 9 is fixedly installed at the output end of the motor 2. A conical spiral blade 10 is fixedly installed on the outer surface of the rotating shaft 9. A set of openings 11 are opened on the upper surface of the conical spiral blade 10. A warning strip 6 is fixedly installed on the outer surface of the feeding hopper body 1. The openings 11 can promote the flow of powder and improve the flowability of powder. A support ring 17 is sleeved on the outer surface of the rotating shaft 9. The bottom surface of each scraper 12 is fixedly installed with the upper surface of the support ring 17. The support ring 17 can reinforce the scraper 12 and improve the stability of the scraper 12. A fixing seat 16 is fixedly installed on the outer surface of the rotating shaft 9. The bottom surface of the fixing seat 16 is fixedly installed with the upper surface of the connecting plate 15. The fixing seat 16 can reinforce the connecting plate 15 and prevent the connecting plate 15 from becoming loose.

[0024] A connecting plate 15 is fixedly installed on the outer surface of the rotating shaft 9. A set of top blocks 18 arranged in a ring at equal intervals are fixedly installed on the outer surface of the connecting plate 15. Two spring paddles 14 are fixedly installed on the inner wall of the feeding hopper body 1. A set of scrapers 12 arranged in a ring at equal intervals are fixedly installed on the outer surface of the rotating shaft 9. The side of each scraper 12 away from the rotating shaft 9 is in contact with the inner wall of the feeding hopper body 1. A set of arc-shaped rods 13 are provided inside the feeding hopper body 1. The top end of each arc-shaped rod 13 is fixedly installed to the bottom end of the rotating shaft 9.

[0025] The working principle of this application is:

[0026] In use, first open the sealing cover 5, and add the powder into the inside of the feeding hopper body 1 through the conical cover 4 and the feed pipe 3. Then start the motor 2, which drives the rotating shaft 9 to rotate. The rotating shaft 9 can synchronously drive the conical spiral blade 10, the connecting plate 15, the scraper 12 and the arc rod 13 to rotate. As the conical spiral blade 10 rotates, it can shear the powder that forms an arch. At the same time, as the scraper 12 rotates with the rotating shaft 9, it can scrape the powder inside the feeding hopper body 1, reducing the powder adhering to the feeding hopper body 1. In addition, as the connecting plate 15 rotates, the top block 18 can move with the connecting plate 15. During the movement of the top block 18, it can push the spring pawl 14 to move, causing the spring pawl 14 to vibrate, thereby causing the feeding hopper body 1 to vibrate. This causes the residual powder to separate from the inner wall of the feeding hopper body 1 under vibration, effectively preventing powder residue.

[0027] 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.
