Description

Technical Field

[0001] The utility model relates to the technical field of air selection, in particular to an air selection device for capsule sorting. Background Art

[0002] Drugs packed in capsules are generally powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easily inhaled into the trachea. Putting these drugs into capsules not only protects the drug properties from being destroyed, but also protects the digestive organs and respiratory tract. Removing the capsule shell may cause drug loss, drug waste, and reduced efficacy. In addition, some drugs need to be dissolved and absorbed in the intestines, and the capsule protects the drug from being destroyed by gastric acid. During the production process of capsules, the empty capsule shells need to be screened out and discarded.

[0003] In the existing capsule production, capsules are generally poured into the hopper on the winnowing machine, and unqualified capsules are blown away and taken out by the wind force of the winnowing machine and the gravity of the capsules. However, it is difficult for the existing winnowing machine to achieve quantitative discharge. Therefore, during the winnowing process, the capsules entering the winnowing machine are too concentrated, which will cause the capsules to fall too densely, causing some unqualified capsules to be blocked during the winnowing process and difficult to be blown away, resulting in poor winnowing effect. In view of this, we propose a winnowing device for capsule sorting. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example:

[0021] This embodiment discloses a wind selection device for capsule sorting, see Figures 1 to 3 , including a steel frame 1, on which a wind selection bin 2 is provided, the wind selection bin 2 is open at one end, a fan 3 is provided in the open end of the wind selection bin 2, a hopper 4 is provided on the top of the wind selection bin 2 for placing wind-selected capsules, a quantitative feeding mechanism 5, a discharge bin A6 and a discharge bin B7.

[0022] like Figures 1 to 3 As shown, a feed port 201 is provided at the top of the air separation bin 2 relative to the quantitative feeding mechanism 5 for putting in capsules, and a discharge port A202 is provided at the bottom of the air separation bin 2 relative to the feed port 201. The capsules filled with drugs fall into the discharge port A202 due to their own greater gravity, and a discharge port B203 is provided at the bottom of the other end of the air separation bin 2; the capsules filled with less drugs or no drugs will be blown to the other end of the air separation bin 2 by the wind force of the fan 3 and fall into the discharge port B203. The air separation bin 2 is provided with guide plates 204 on the inner walls on both sides of the discharge port A202, and the tops of the two guide plates 204 are curved toward the other end of the air separation bin 2. The guide plates 204 are used to concentrate the wind of the fan 3 to the top of the air separation bin 2 and blow it toward the descending capsules, thereby increasing the wind force and improving the air separation effect. At the same time, the guide plates 204 can also isolate the capsules after air separation to prevent the capsules from being mixed again after air separation.

[0023] Specifically, Figures 1 to 3 As shown, the bottom of the discharge port A202 is fixedly connected to a discharge bin A6 inclined toward one side of the air selection bin 2 for discharging qualified capsules, and the bottom of the discharge port B203 is fixedly connected to a discharge bin B7 inclined toward the other side of the air selection bin 2 for discharging unqualified capsules.

[0024] like Figures 1 to 3 As shown, the quantitative feeding mechanism 5 is arranged between the hopper 4 and the air separation bin 2.

[0025] Specifically, Figures 1 to 3As shown, the quantitative feeding mechanism 5 includes a feeding bin 501, a running roller 502 and a belt motor 503. The top of the feeding bin 501 is connected to the bottom of the hopper 4. The running roller 502 is arranged in the feeding bin 501, and one end of the running roller 502 is rotatably connected to the inner wall of one end of the feeding bin 501 through a rotating shaft. The other end of the running roller 502 is provided with a transmission shaft 504, one end of the transmission shaft 504 is penetrated through the bin wall at the other end of the feeding bin 501 and extends to the outside and is fixedly connected with a driven gear 505. The motor 503 is fixedly installed on the top bin wall of the air separation bin 2 by screws, and the output end of the motor 503 is provided with a driving gear 506, and the driving gear 506 and the driven gear 505 are connected by a chain. The strip 507 is meshed for transmission, and a number of operating grooves 5021 extending to both ends of the operating roller 502 are evenly spaced on the surface of the operating roller 502. The motor 503 is driven by an external control mechanism to drive the driving gear 506 to rotate, and the driving gear 506 drives the driven gear 505 to rotate through the chain 507. The driven gear 505 drives the operating roller 502 to rotate in the feeding bin 501 through the transmission shaft 504. When the open end of the operating groove 5021 is connected to the bottom of the hopper 4, the capsule falls into the operating groove 5021 from the bottom of the hopper 4, and the operating roller 502 continues to rotate to rotate the open end of the operating groove 5021 containing the capsule to the top of the feed port 201, and the capsule falls into the air separation bin 2.

[0026] Further, such as Figure 2 , Figure 3 As shown, the feed port 201 is connected to the bottom of the feed bin 501 .

[0027] Further, if Figure 2 , Figure 3 As shown, the side of the running roller 502 is tangent to the inner walls on both sides of the bottom discharge end of the hopper 4, and the running groove 5021 is adapted to the bottom discharge end of the hopper 4 to prevent the capsule from entering the gap between the running roller 502 and the hopper 4 and causing material jamming.

[0028] Working principle: When the novel device is used, the fan 3 is first driven by an external control mechanism, and the wind blown by the fan 3 is drained by the guide plate 204 and concentrated to the top of the air selection bin 2, and the un-air-selected capsules are poured into the hopper 4. The motor 503 is driven by the external control mechanism to drive the driving gear 506 to rotate, and the driving gear 506 drives the driven gear 505 to rotate through the chain 507, and the driven gear 505 drives the running roller 502 to rotate in the feeding bin 501 through the transmission shaft 504. When the open end of the running slot 5021 is connected to the bottom of the hopper 4, the running roller 5021 is driven to rotate in the feeding bin 501. At this time, the capsule falls into the running groove 5021 from the bottom of the hopper 4, and the running roller 502 continues to rotate to rotate the open end of the running groove 5021 containing the capsule to the top of the feed port 201, and the capsule falls into the air selection bin 2. The wind generated by the fan 3 blows toward the capsule. The capsules partially filled with drugs fall into the discharge port A202 due to their own greater gravity and are discharged from the discharge bin A6. The capsules filled with less drugs or no drugs will be blown to the other end of the air selection bin 2 by the wind force of the fan 3 and fall into the discharge port B203, and are discharged from the discharge bin B7, completing the capsule air selection.
