[0002] Pharmaceutical preparations are made to meet the needs of treatment or prevention, according to certain dosage form requirements, and can ultimately be provided to the subject for use. Pharmaceutical preparations can be in the form of sheets or capsules. Sheet or capsule-shaped pharmaceutical preparations need to be screened before packaging to remove the debris and powder therein. When screening sheet or capsule-shaped pharmaceutical preparations, a drum-shaped screening machine can be used. When in use, the pharmaceutical preparation enters the drum of the screening machine from the feed port of the screening machine. During the process of the pharmaceutical preparation being transported forward in the drum, the powder debris will leak out from the residue leakage hole on the drum, thereby achieving the effect of cleaning the pharmaceutical preparation. However, the current pharmaceutical drum screening machine still has the problem of not being able to clean up the debris and powder in the pharmaceutical preparation when in use. Summary of the invention

[0003] The utility model aims to provide a device for removing debris and powder for dispensing medicine preparations, so as to overcome the defect that the debris and powder in the medicine preparations cannot be cleaned up completely when the drum sieve machine in the prior art is used.

When in use, the pharmaceutical preparation rotates with the spiral blades in the drum in the drum and moves from the feed port to the discharge port. The blowing pipe inserted into the drum blows the pharmaceutical preparation in the drum through multiple blowing ports, blows the powder on the surface of the pharmaceutical preparation down, and disturbs the pharmaceutical preparation at the same time, so that the powder and debris can be better sucked into the exhaust pipe. The utility model is provided with a vibration motor, and the vibration motor can make the shell and the drum vibrate to a certain extent, and the pharmaceutical preparation in the drum vibrates, so that the debris and powder can be better sucked into the exhaust pipe. In summary, the utility model can effectively enhance the cleaning effect of the pharmaceutical preparation when it passes through the drum, making the cleaning more thorough.

[0024] A device for removing debris and powder for dispensing pharmaceutical preparations comprises a housing 1, a support leg 14 is installed at the bottom of the housing 1 and supported by the support leg 14, and the support legs 14 are installed on both sides of the bottom of the housing 1. A roller 2 is rotatably installed in the housing 1, and the roller 2 is tilted, and the height of the feed end of the roller 2 is higher than the height of the discharge end, so that the pharmaceutical preparations entering the roller 2 can move better in the roller 2. A spiral blade 35 is installed in the roller 2, and after the pharmaceutical preparations enter the roller 2, they will move from the feed end to the discharge end along with the spiral blade 35.

[0025] The two ends of the housing 1 are respectively installed with bearings 4 that match the roller 2. The two ends of the roller 2 are respectively supported by the bearings 4 and rotate relative to the housing 1. The bearing 4 adopts a turntable bearing. The turntable bearing is a prior art, which usually includes an inner ring 20, an outer ring 21, rolling elements, isolation blocks and other structures. The outer ring 21 and the inner ring 20 can rotate relative to each other. The outer ring 21 of the rotating bearing 4 is fixedly connected to the housing 1 by bolts. The two sides of the roller 2 are respectively installed with annular convex edges 22. The annular convex edges 22 are fixedly connected to the inner ring 20 of the turntable bearing by bolts, thereby connecting the roller 2 to the turntable bearing. The utility model makes the outer ring 21 of the turntable bearing fixedly connected to the housing 1, and the inner ring 20 of the turntable bearing fixedly connected to the roller 2, thereby making the turntable bearings on both sides support the roller 2 well, so that the roller 2 can only rotate relative to the housing 1.

[0026] The feed end of the roller 2 is provided with a gear ring 5, one side of the shell 1 is connected to a support plate 6, a motor 7 is mounted on the support plate 6, an output shaft of the motor 7 is connected to a driving gear 8 meshing with the gear ring 5, and the motor 7 drives the gear ring 5 to rotate through the driving gear 8, thereby driving the roller 2 to rotate.

[0027] The support plate 6 is provided with a feed barrel 10 through a support frame 9. The feed barrel 10 is arranged parallel to the drum 2, that is, the feed barrel 10 is also arranged tilted, so that the height of the feed end of the feed barrel 10 is higher than the height of the discharge end. One end of the feed barrel 10 is inserted into the feed end of the drum 2. The feed barrel 10 is used to transport the pharmaceutical preparation to the feed end of the feed barrel 10. The feed barrel 10 is fixedly mounted on the support plate 6 through the support frame 9, and the feed barrel 10 does not rotate with the drum 2. The feed end of the feed barrel 10 is connected to the vertical barrel 26, and a feed hopper 27 is provided at the top of the vertical barrel 26. When in use, the pharmaceutical preparation enters from the feed hopper 27 at the top of the vertical barrel 26 and slides to the feed end of the feed barrel 10. Due to the tilted setting of the feed barrel 10 and the action of the vibration motor 36, the pharmaceutical preparation in the feed barrel 10 slides into the drum 2.

The utility model forms a space for extracting debris powder between the bearings 4 on both sides of the shell 1 and the drum 2 by installing bearings 4 on both sides of the shell 1. When the exhaust fan extracts the air in this space, the air in this space almost flows from the drum 2, so that the exhaust fan has a better exhaust effect on the pharmaceutical preparation in the drum 2. The exhaust fan connected to the exhaust pipe 13 can be used as a part of a vacuum cleaner; three exhaust ports 12 are installed at the bottom of the shell 1 along the length direction of the shell 1. By setting three exhaust ports 12, a better exhaust effect can be achieved.
