Description

Technical Field

[0001] The utility model relates to the technical field of medicine sorting, in particular to a multifunctional hard capsule shape defect sorting machine. Background Art

[0002] Drugs packaged 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. Encapsulating these drugs not only protects the drug's medicinal 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 capsules protect the drugs from being destroyed by gastric acid. In medicine, it refers to a capsule made of special film-forming materials (such as gelatin, cellulose, polysaccharides, etc.), into which the contents (such as various powdered and liquid drugs, etc.) or according to the dosage are placed for easy swallowing.

[0003] Therefore, after capping, capsules must be inspected for any signs of cap insertion, length change, or cap separation. Failure to do so could seriously affect the effectiveness of the medication when taken by the patient. Currently, some companies use manual inspection to inspect capsules, severely impacting drug production efficiency. Others rely on simple machine sorting. For example, patent publication number CN221231003U discloses a capsule sorting device. This device provides only simple sorting, with poor results, resulting in some defective capsules remaining after sorting. Utility Model Content

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] This embodiment relates to a multifunctional hard capsule shape defect sorting machine, an exemplary structure of which is as follows: Figure 1-6 shown.

[0034] Overall, if Figure 1 and 4 As shown, the multifunctional hard capsule shape defect sorting machine includes a base 1, a first sorting unit provided on the base 1, and a first collecting box 2. The structure of the first sorting unit includes a vibrator 3 provided on the base 1, a tray 4 provided on the vibrator 3, and a first screening plate 5 provided on the tray 4, wherein the first screening plate 5 is provided with a plurality of first screening holes 6; the tray 4 is tilted toward the first collecting box 2, and the outlet of the tray 4 is provided corresponding to the inlet of the first collecting box 2. The vibrator 3 is mounted on the base 1 through a base, and a covering plate 19 is provided between the vibrator 3 and the base 1, and a gasket 20 is installed at the bottom of the vibrator 3 to cushion the vibration generated by the vibrator 3. It should be noted that the degree of inclination of the tray 4 and the first screening plate 5 on the tray 4 is relatively small.

[0035] Secondly, the first screening plate 5 is arranged parallel to the tray 4, that is, the first screening plate 5 and the tray 4 are tilted in the same direction at the same time. After the vibrator 3 vibrates the capsules on the first screening plate 5, the defective capsules entering the tray 4 are moved in the tilted direction of the tray 4 under the action of the vibration force and enter the inlet of the collection box through the outlet of the tray 4.

[0036] In addition, if Figure 5As shown, a perforation 7 is provided at the bottom of one side of the first collection box 2, and a pull-out slot 8 is provided within the perforation 7. The pull-out slot 8 is provided inside the first collection box 2. The pull-out slot 8 passes through the perforation 7 and slides within the first collection box 2. When defective capsules enter the first collection box 2, they fall into the pull-out slot 8. The pull-out slot 8 can then be pulled out to remove the defective capsules, making cleaning easier. Furthermore, a buffer slot 9 is provided at the end of the first screening plate 5 away from the first collection box 2, and the outlet of the buffer slot 9 is located above the first screening plate 5. Capsules to be sorted are first accumulated in the buffer slot 9 to prevent too many capsules from entering the first screening plate 5 and affecting the screening quality.

[0037] In this embodiment, if Figure 5 As shown, the apparatus further includes a second sorting unit mounted on the base 1. The second sorting unit comprises an outer housing 10 connected to the base 1 and a motor 11, which rotates a screening ring 12 disposed within the outer housing 10. The outer wall of the screening ring 12 is provided with a plurality of second screening holes 13. The output shaft of the motor 11 is connected to the rotating shaft of the screening ring 12 via a belt 14. The outer housing 10 has an inlet, which is connected to the end of the first screening plate 5 near the outer housing 10. A sealing plate 15 is provided at one end of the screening ring 12, and the other end is connected to the inlet of the outer housing 10. Capsules that pass through the first screening plate 5 enter the screening ring 12 and rotate with the screening ring 12. Complete capsules, under the action of centrifugal force, pass through the second screening holes 13 and fall into the outer housing 10. The outer housing 10 has an outlet at the bottom, through which the complete capsules are collected.

[0038] Among them, Figure 6 As shown, the screening ring 12 is composed of eight plates spliced ​​together, and a flange ring is fixed on the inner wall of the outer cover 10, and another flange ring is provided to be rotatably connected to another flange ring, and the rotating shaft of the screening ring 12 is fixedly connected to the flange ring so that the screening ring 12 can rotate in the outer cover 10.

[0039] In this embodiment, the second sorting unit further includes a second collecting box 16, which passes through one side of the outer cover 10 and extends into the interior of the screening ring 12. The collecting groove of the second collecting box 16 is located below the top of the inner wall of the screening ring 12. Figure 7 As shown, a strip brush 17 is installed inside the outer cover 10. Strip brush 17 is arranged axially along the screening ring 12, with its bristles contacting the top of the inner wall of the screening ring 12. Defective capsules remaining in the screening ring 12 are drawn into the second screening holes 13 by centrifugal force. As the screening ring 12 rotates, the defective capsules carried by the screening ring 12 reach the top, where they come into contact with the bristles of strip brush 17, brushing the defective capsules off and dropping them into the second collection box 16.

[0040] Secondly, an inclined slot 18 is connected between the end of the first screening plate 5 close to the outer cover 10 and the inlet of the outer cover 10. The inclined slot 18 is inclined downward toward the inlet of the outer cover 10, so that the capsules screened on the first screening plate 5 can enter the screening hole through the inclined slot 18 for re-screening.

[0041] In this embodiment, a control unit is also included, and both the vibrator 3 and the motor 11 are connected to the control unit by signal. The control unit is a conventional PLC control system that only needs to be able to control the start / stop of the vibrator 3 and the motor 11.

[0042] The working process of this embodiment is as follows:

[0043] First, the filled capsules are placed in the buffer tank 9. The motor 11 and vibrator 3 are started. Under the action of the vibrator 3, the capsules in the buffer tank 9 enter the first screening plate 5. The capsules separated by the cap on the first screening plate 5 are vibrated, and the capsules are discharged through the first screening hole 6 into the tray 4. Under the action of the vibration, the defective capsules in the tray 4 pass through the outlet of the tray 4 and enter the first collection box 2. The intact capsules on the first screening plate 5 enter the screening ring 12 through the chute 18. The screening ring 12 rotates under the drive of the motor 11. The capsules that have entered the screening ring 12 follow the rotation of the screening ring 12. These capsules continue to rotate under the action of centrifugal force, causing the intact capsules to pass through the second screening hole 13 and be collected through the outlet at the bottom of the outer cover 10. Capsules with excessive diameters are retained in the screening ring 12 and carried to the top of the screening ring 12. They are then brushed off by the strip brush 17 and fall into the second collection box 16.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
