Description

Technical Field

[0001] The utility model relates to the technical field of capsule screening equipment, in particular to a capsule shell screening device. 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. These drugs are placed in capsules to protect the drug's medicinal properties from being destroyed, and also to protect 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] For example, the Chinese utility model patent (CN217616064U) discloses a capsule shell screening device for capsule production, which records: "Capsules are put into the capsule screen plate from above and scattered on the capsule screen plate. The capsule screen plate is connected to the T-shaped funnel. The capsule screen plate is driven by the cylinder to limit the convex edge and the cavity in the receiving plate to slide and match, thereby screening the capsules. The arc plate enables the capsules to slide quickly to the surface of the capsule screen plate. When the capsules fall to the air supply port, the empty capsules are blown out of the capsule group by adjusting the wind force. The full-packed capsules fall normally to the full-packed capsule area of ​​the capsule receiving drawer, and the empty capsules are blown to the inner wall of the T-shaped funnel and fall to the empty-packed capsule area. The capsule receiving drawer slides with the concave convex edge at the lower end of the T-shaped funnel, and the operation is simple." It also records: "In the prior art, empty capsule shells are generated during the production of soft capsules. The empty capsule shells need to be screened out. The screening device currently used has a relatively complex structure, high maintenance cost, and it is not easy to classify and collect the capsules after screening."

[0004] In summary, it can be seen that the existing technology of blowing out empty capsules through a fan has the following technical problems: when the capsules fall to the fan, if too many capsules fall at the same time, the capsules will overlap and block each other, making the screening results unstable, and the fan will accumulate dust after long-term use, which can easily cause contamination to the capsules. For this reason, the present application proposes a capsule shell screening device to solve the technical problems mentioned in the above patents and provide a new technical solution.

[0033] The capsule shell screening device provided by the present invention can control the amount of capsules falling during capsule screening through the structural design of the screening mechanism 2, thereby preventing too many capsules from falling at the same time, thereby improving the stability of the screening results.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figure 1-Figure 3 A capsule shell screening device comprises: an outer box 1, a screening mechanism 2, a filtering mechanism 3, a take-and-put port 5, and a moving wheel 6. The outer box 1 is provided with a screening mechanism 2 for screening empty capsules, and the outer box 1 is provided with a filtering mechanism 3 for filtering air. The outer side of the lower end of the outer box 1 is provided with a take-and-put port 5, and the four end corners of the bottom of the outer box 1 are fixedly connected to the moving wheels 6.

[0037] Specifically, the screening mechanism 2 includes an inclined plate 7, a sieve plate 8, a strip groove 9, a mounting seat 10, a fan 13, a collection box 14, a capsule solid package area 15, a capsule empty package area 16, an exhaust port 29 and a control component. The inclined plate 7 is located at the upper end of the outer box 1. The inclined plate 7 is fixedly connected to the outer box 1. One side of the inclined plate 7 is fixedly connected to the sieve plate 8. The bottom of the sieve plate 8 is fixedly connected to the mounting seat 10. The surface of the sieve plate 8 is provided with a strip groove 9. The size of the strip groove 9 only allows a single capsule to pass through. The strip grooves 9 pass through the sieve plate 8 and the mounting seat 10 and extend to the bottom of the mounting seat 10. A fan 13 is embedded and fixedly connected to the surface of the outer box 1 at a position corresponding to the strip grooves 9. An exhaust port 29 is provided on the surface of the outer box 1 on the side away from the fan 13. A collecting box 14 is slidably connected to the bottom of the outer box 1 at a position corresponding to the taking and placing port 5. A partition is provided inside the collecting box 14, which divides the interior of the collecting box 14 into a capsule full package area 15 and a capsule empty package area 16.

[0038] Furthermore, the control component includes a drive motor 4, a rotating column 11 and a receiving groove 12. The internal rotation of the mounting base 10 is connected to the rotating column 11. The receiving grooves 12 are evenly opened on the surface of the rotating column 11 and at the position corresponding to the strip groove 9. The size of the receiving groove 12 is equal to the size of the capsule. The drive motor 4 is fixedly connected to the outside of the outer box 1 and at the position corresponding to the rotating column 11. The output end of the drive motor 4 is fixedly connected to the rotating column 11.

[0039] It can be seen that when in use, the capsules to be screened can be placed on the inclined plate 7, and the capsules will slide along the inclined plate 7 to the position above the sieve plate 8 and fall into the strip groove 9. The capsules pass through the strip groove 9 and fall into the receiving groove 12 on the surface of the rotating column 11. Then the driving motor 4 is started to drive the rotating column 11 to rotate, so that the capsules are finally discharged from the bottom end of the strip groove 9 and to the position of the fan 13. The fan 13 then blows air to screen the capsules discharged from the strip groove 9, so that the empty capsule shells are blown by the fan 13 and fall into the capsule empty bag area 16, and finally the screening of the capsule shells is completed.

[0040] Example 2:

[0041] The capsule shell screening device provided in Example 1 is further optimized. Specifically, Figure 4-Figure 5 As shown, further, the filtering mechanism 3 includes a filter screen plate 17 and a fixing assembly. The filter screen plate 17 is arranged outside the outer box 1 and at a position corresponding to the fan 13. The filter screen plate 17 is detachably connected to the outer box 1 through the fixing assembly.

[0042] Furthermore, the fixing assembly includes a rotating head 18, a positioning block 19, a boss 20, a spring 21, a push rod 22 and a button 23. The rotating head 18 is rotatably connected to the outer box 1, and the boss 20 is slidably connected inside the rotating head 18. The end of the boss 20 located inside the rotating head 18 is fixedly connected to the spring 21, and the end of the spring 21 away from the boss 20 is fixedly connected to the rotating head 18. Positioning blocks 19 are provided on both sides of the rotating head 18 and at positions corresponding to the boss 20. The positioning blocks 19 are fixedly connected to the filter screen 17. The positioning block 19 is slidably connected to the push rod 22 inside the positioning block 19, and the push rod 22 extends to the outside of the positioning block 19. The end of the push rod 22 extending to the outside of the positioning block 19 is fixedly connected to the button 23.

[0043] It can be seen that when the fan 13 is in use, the filter plate 17 can filter the air sprayed by the fan 13 to prevent dust in the air from contaminating the capsule. When the dust on the surface of the filter plate 17 accumulates to a certain extent, the button 23 can be manually pressed to make the push rod 22 push the boss 20 into the interior of the rotating head 18, so as to release the limit of the rotating head 18. Then, the rotating head 18 can be turned over to disengage the rotating head 18 from the positioning block 19, and the filter plate 17 can be removed from the outside of the outer box 1.

[0044] Example 3:

[0045] The capsule shell screening device provided in Example 1 is further optimized. Specifically, Figure 6 As shown, further, a limiting component is provided inside the taking-in and putting-out opening 5 for limiting the movement of the collecting box 14 .

[0046] Furthermore, the limiting assembly includes a short rod 24, a slide 25, a slide 26, a spring 27 and a stopper 28. A slide 26 is provided on the inner side of the taking and releasing port 5 and at a position corresponding to the collection box 14. A slide 1 25 is provided on the surface of the outer box 1 and at a position corresponding to the slide 26. The slide 1 25 is connected to the interior of the slide 2 26. The interior of the slide 2 26 is slidably connected to the stopper 28. The interior of the slide 1 25 is slidably connected to the short rod 24. One end of the short rod 24 extends to the interior of the slide 2 26. The end of the short rod 24 located inside the slide 26 is fixedly connected to the upper end of the stopper 28. The outer side of the stopper 28 is sleeved with a spring 27. One end of the spring 27 is fixedly connected to the slide 2 26, and the other end of the spring 27 is fixedly connected to the stopper 28.

[0047] It can be seen that when in use, the block 28 can limit the collection box 14 inside the outer box 1 to prevent the device from sliding out of the outer box 1 during operation. When the screening is completed, the short rod 24 can be pulled upward to drive the block 28 to move into the inside of the second slide 26, so that the block 28 loses its obstruction on the collection box 14, and the collection box 14 can be pulled out from the take-out port 5.
