Description

Technical Field

[0001] This utility model relates to granulators, specifically to a powder feeding device for a dry granulator. Background Technology

[0002] Granulators are specialized equipment used in pharmaceuticals, food, and chemical industries. The powder feeding device is used to transport powder. Traditional powder feeding devices typically use small-sized hoppers with a moving paddle inside to convey the powder downwards. However, in actual production, large amounts of powder may be rapidly fed into the hopper, and the aforementioned small-sized hopper cannot meet this demand. Additionally, some hoppers that are wider at the top and narrower at the bottom have appeared on the market. In actual use, the neck formed by the inward curve in the middle of these hoppers is prone to causing powder to accumulate in an arch-like pattern, preventing the powder from falling and affecting normal powder feeding operations. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a powder feeding device for a dry granulator to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A powder feeding device for a dry granulator, characterized in that: it includes a material hopper, the material hopper comprising an upper feeding section and a lower feeding section, a picking plate is provided in the upper feeding section, one end of the picking plate extends to the junction of the upper feeding section and the lower feeding section, a rotating shaft is provided in the lower feeding section, a moving feeding paddle is provided on the rotating shaft, the moving feeding paddle can squeeze the picking plate to swing, and a discharge port is provided at the bottom of the lower feeding section.

[0006] A vibrator is installed at the upper feed section.

[0007] The lower feeding section is provided with a fixed feeding comb near the discharge port, and the moving feeding paddle is provided with a clearance groove corresponding to the fixed feeding comb.

[0008] The rotating shaft has an air passage inside, and an air inlet connector is provided at the air inlet end of the air passage. The air outlet of the air passage is located inside the lower feeding part, and the air outlet is located near the rotating support part of the rotating shaft.

[0009] The above-mentioned technical solution provides a dry granulator powder feeding device, which is equipped with a picking plate, one end of which extends to the junction of the upper feeding section and the lower feeding section. When the moving feeding paddle is in motion, it can squeeze the picking plate to swing, thereby moving the powder in the neck position of the material barrel, avoiding the accumulation of powder in an arch bridge shape, and ensuring that the powder can fall smoothly into the lower feeding section.

[0013] Figure 3 for Figure 2 A magnified view of the area pointed to by A in the middle. Detailed Implementation

[0014] As shown in the figure, the present invention discloses a powder feeding device for a dry granulator, including a material hopper, which includes an upper feeding section 1 and a lower feeding section 8. A picking plate 3 is provided in the upper feeding section 1, and one end of the picking plate 3 extends to the junction of the upper feeding section 1 and the lower feeding section 8. A rotating shaft 5 is provided in the lower feeding section 8, and a moving feeding paddle 4 is provided on the rotating shaft 5. The moving feeding paddle 4 can squeeze the picking plate 3 to swing. A discharge port 7 is provided at the bottom of the lower feeding section 8.

[0015] Furthermore, a vibrator 2 is provided corresponding to the upper feed section 1. With the above structure, the operation of the vibrator 2 can drive the upper feed section 1 to vibrate, thereby allowing the powder to fall more smoothly.

[0016] Furthermore, the lower feeding section 8 is equipped with a fixed feeding comb 6 near the discharge port 7, and the moving feeding paddle 4 is equipped with a relief groove 11 corresponding to the fixed feeding comb 6. With the above structure, the moving feeding paddle 4 can cooperate with the fixed feeding comb 6 to move the powder, making the powder conveying more stable and reliable, and at the same time making the powder conveying amount more accurate.

[0017] Furthermore, an air passage 10 is provided inside the rotating shaft 5, and an air inlet connector 9 is provided at the air inlet end of the air passage 10. The air outlet 12 of the air passage 10 is located inside the lower feeding section, and the air outlet 12 is located near the rotating support part of the rotating shaft 5. The rotating support part refers to the rotating support bearing and sealing end corresponding to the rotating shaft 5. By adopting the above structure, an airtight seal can be achieved at the transmission structure, preventing powder from entering the transmission structure and ensuring the stability of equipment operation.

[0018] The working principle of this utility model is as follows: A large amount of powder is first sent to the upper feeding section 1 for collection, and at the same time, some powder will fall into the lower feeding section 8. By controlling the rotating shaft 5 to drive the moving feeding paddle 4, the moving feeding paddle 4 can cooperate with the fixed feeding comb 6 to move the powder, so that the powder is sent out from the discharge port 7 of the lower feeding section 8. At the same time, when the moving feeding paddle 4 moves, it can squeeze the picking plate 3 to swing, thereby moving the powder in the neck position of the material barrel, avoiding the accumulation of powder in an arch bridge, and ensuring that the powder can fall smoothly into the lower feeding section.
