Description

Technical Field

[0001] This application belongs to the field of capsule production technology, specifically a sorting device for capsule pharmaceuticals. Background Technology

[0002] In medicine, capsules refer to sac-like objects made of special film-forming materials, into which the contents are filled according to a dosage for easy swallowing. Drugs encapsulated are generally powders or granules that are irritating to the esophagus and gastric mucosa, or those with an unpleasant taste, high volatility, easy decomposition by saliva in the mouth, or easy inhalation into the trachea. Encapsulating these drugs protects their efficacy and also protects the digestive and respiratory tracts. In small pharmaceutical factories, capsule production is limited, and manual sieving and weighing of powder is typically used. While this process doesn't require mechanical assistance, it has limitations. If a large number of unevenly sized powder particles are introduced into the capsule shell during filling, it affects the net content of the drug in each capsule. Inaccurate control of the net content directly impacts the efficacy and the effectiveness of the drug in treating the disease.

[0003] For example, patent number CN219168922U discloses a screening device for capsule granule production, belonging to the field of capsule processing technology. It includes a machine body with a mounting frame fixedly installed on its upper part. Two fixing blocks are fixedly installed on the inner walls of both the front and rear sides of the mounting frame. A sorting box is movably installed inside the mounting frame. Two slide rails are fixedly installed on both the front and rear sides of the sorting box, with the fixing blocks slidably mounted on the inner walls of the opposing slide rails. A driving mechanism that drives the sorting box to move up and down is fixedly installed on the outer surface of the mounting frame. By setting up the sorting box, the raw materials are thoroughly screened multiple times through sieve plates one, two, and three within the sorting box. The screened raw materials then enter the material box through the corresponding discharge channel, eliminating the need for manual sieving. This solves the problem of uneven particle size, allows for more precise control of the net drug content of individual capsules, and thus ensures the efficacy of the drug.

[0004] During the use of this device, the following problems were found: Due to the inclined design of the sieve plates, when capsule particles enter the uppermost sieve plate, the accumulation effect may cause the uppermost capsule particles to not pass through the sieve holes in time and roll directly into the discharge channel, eventually reaching the collection hopper. Similarly, the lower sieve plates two and three face the same problem, resulting in insufficient sorting of capsule particles. In addition, since most capsule particles cannot be perfectly round or granular during manufacturing, the sieve holes on the sieve plates may become clogged with particles after a period of screening, further causing screening errors. Therefore, to solve this problem, it is necessary to propose a capsule sorting device. Utility Model Content

[0005] The purpose of this application is to provide a sorting device for capsule pharmaceuticals in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A sorting device for capsule drugs includes a support platform, on both sides of the top of the support platform, a bracket is fixedly installed, a sieve cylinder is rotatably installed on the top of the bracket via a bearing, a rotary joint is fixedly installed at both ends of the sieve cylinder, an inlet pipe is fixedly installed at the rotating end of the rotary joint on the left side, an air pump is fixedly installed on the left side of the support platform, the exhaust end of the air pump is connected to the bottom of the inlet pipe and the rotating end of the rotary joint via a rigid pipe, and an outlet pipe is fixedly installed at the rotating end of the rotary joint on the right side.

[0007] The outer periphery of the screening cylinder is provided with closely spaced screen holes. Both sides of the outer wall of the screening cylinder are fixedly installed with side plates arranged in opposite directions around the periphery. The inner side of the side plates is slidably installed with a slide rod with a spring at the end. On the side of the slide rod facing the screening cylinder, a plurality of unblocking rods are fixedly installed opposite to the screen holes. On the side of the slide rod away from the screening cylinder, a roller is rotatably installed. An arc panel located at the top of the screening cylinder is fixedly installed on the rear side of the top of the support platform. A roller groove is fixedly installed on the top of the support platform below the screening cylinder.

[0008] A track plate is fixedly installed on the top right side of the support platform, and a rack is slidably installed on the front side of the track plate. A second gear ring is engaged with the front side of the rack and fixed to the rotating end of the right rotary joint.

[0009] In a preferred embodiment, the feed pipe is designed to be inclined upward on the left, a feed tray is fixedly installed at the top of the feed pipe, a sealing cover is provided on the top of the feed tray, and the initial position of the discharge pipe is a structure designed to be inclined upward on the right.

[0010] In a preferred embodiment, a first toothed ring is provided on the outer periphery of the fixed end of the rotary joint on the left side, and a gear is engaged at the bottom of the first toothed ring. The rotational power of the gear comes from a first drive motor fixedly installed on the left end of the gear.

[0011] In a preferred embodiment, the inner side of the side plate is provided with a sliding groove adapted to the slide rod, and the two sliding ends of the slide rod facing the screening cylinder are fixedly connected to the sliding groove by springs.

[0012] In a preferred embodiment, the front side of the track plate is provided with a limiting movement groove adapted to the rack, and a lead screw is threaded onto the rack. The rotational power of the lead screw comes from a second drive motor fixedly installed at the bottom of the track plate.

[0013] In a preferred embodiment, a collection box is placed on the top of the support platform below the front end of the chute, and a collection cylinder is placed on the right side of the support platform below the discharge pipe.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0015] In this application, through the above design, when using the sorting device to screen capsule granules, first open the sealing cover on the feed tray and pour the granules into the feed tray. Note that the amount of granules poured in should be such that it reaches the bottom of the screening cylinder and is not higher than the level below the inner diameter of the rotating end of the rotary joint. Then, turn on the air pump at a low setting to induce airflow. The airflow will blow the granules in the feed pipe toward the screening cylinder to help them quickly enter the screening cylinder. At this time, since the initial position of the discharge pipe is tilted upwards at the right end, the airflow will further induce airflow. The air pump is set to low speed, causing the injected air to exit from the right end of the discharge pipe. The medicine particles inside the sieve cylinder remain inside and are constantly moved by the injected air. Then, the first drive motor is activated, driving the gear to mesh with the first gear ring to rotate. The rotation of the first gear ring, through the fixed end of the rotary joint, drives the sieve cylinder to rotate as well. The rotation of the sieve cylinder continuously rotates the medicine particles inside, causing those that meet the size requirements to exit through the sieve holes and fall onto the trough for collection, ultimately rolling into the collection box for final collection. During this process, particles that do not meet size requirements may become stuck in the sieve holes, affecting sieving. When the sliding rod on the outer wall of the sieving cylinder rotates to its highest position, it encounters an arc-shaped panel. This panel presses against the rollers on the outer surface of the sliding rod, causing it to compress towards the sieving cylinder. This allows the unblocking rod on the sliding rod to insert into the sieve holes, squeezing the particles stuck inside out into the sieving cylinder, thus clearing the blockage and ensuring continuous sieving. After the sieving cylinder has been rotating and sieving for a period of time, if no action is taken for an extended period... When medicinal particles are discharged from the sieve holes on the sieve cylinder, it indicates that the sieving time has been sufficient. At this point, start motor number two to drive the lead screw to rotate, thereby controlling the rack to move upward. This causes the rack to mesh with the second gear ring and rotate 180 degrees. At this time, the right end of the discharge pipe turns downward and faces the top of the collection cylinder. Finally, start the air pump at its highest setting while keeping the sieve cylinder rotating. With the large air volume injected by the air pump, the medicinal particles in the sieve cylinder that do not meet the size requirements are discharged into the collection cylinder through the discharge pipe for recycling, thus completing the sorting of medicinal particles.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Reference Figure 1 , 2 3. A sorting device for capsule medicine, comprising a base 1, with supports 2 fixedly installed on both sides of the top of the base 1, a sieve cylinder 3 rotatably installed on the top of the supports 2 via bearings, and rotary joints 4 fixedly installed at both ends of the sieve cylinder 3. A feed pipe 5 is fixedly installed at the rotating end of the left rotary joint 4, the feed pipe 5 is designed to be inclined upward on the left, a feed tray 6 is fixedly installed at the top of the feed pipe 5, and a sealing cover is provided on the top of the feed tray 6. The initial position of the discharge pipe 8 is a structure designed to be inclined upward on the right. An air pump 7 is fixedly installed on the left side of the base 1, and the exhaust end of the air pump 7 is connected to the bottom of the feed pipe 5 and the rotating end of the rotary joint 4 via a rigid pipe. The discharge pipe 8 is fixedly installed at the rotating end of the right rotary joint 4. A toothed ring 9 is provided on the outer periphery of the fixed end of the left rotary joint 4, and a gear 10 is meshed at the bottom of the toothed ring 9. The rotational power of the gear 10 comes from a drive motor fixedly installed at the left end of the gear 10.

[0022] With the above design, when using the sorting device to screen capsule granules, first open the sealing cover on the feed tray 6 and pour the granules into the feed tray 6. Note that the amount of granules poured in should be such that it reaches the bottom of the screening cylinder 3 and is not higher than the horizontal plane below the inner diameter of the rotating end of the rotary joint 4. Then turn on the air pump 7 to inject air at a low setting. At this time, the injected air will blow the granules in the feed pipe 5 into the screening cylinder 3 to help the granules enter the screening cylinder 3 quickly. Since the initial position of the discharge pipe 8 is tilted upward on the right end, and the air pump 7 is injecting air at a low setting, the injected air will be discharged from the right end of the discharge pipe 8, while the granules in the screening cylinder 3 remain in the screening cylinder 3 and are constantly moved by the injected air.

[0023] Reference Figure 1 ,2 3. The outer periphery of the screening cylinder 3 is provided with closely arranged screen holes 11. Both sides of the outer wall of the screening cylinder 3 are fixedly installed with side plates 12 that are circumferentially opposite to each other. The inner side of the side plate 12 is slidably installed with a slide rod 13 with a spring at the end. The inner side of the side plate 12 is provided with a slide groove that matches the slide rod 13. The two sliding ends of the slide rod 13 facing the screening cylinder 3 are fixedly connected to the slide groove by springs. Multiple unblocking rods 14 that are opposite to the screen holes 11 are fixedly installed on the side of the slide rod 13 facing the screening cylinder 3. Rollers 15 are rotatably installed on the side of the slide rod 13 away from the screening cylinder 3. The top rear side of the support platform 1 is fixedly installed with an arc panel 16 located at the top of the screening cylinder 3. The top of the support platform 1 is fixedly installed below the screening cylinder 3 with a roller groove 17. The top of the support platform 1 is placed below the front end of the roller groove 17.

[0024] With the above design, after the medicine particles reach the screening cylinder 3, the first drive motor is started to drive the gear 10 to mesh with the first gear ring 9 to rotate. The rotation of the first gear ring 9 drives the screening cylinder 3 to rotate together through the fixed end of the rotary joint 4. The rotation of the screening cylinder 3 will continuously drive the internal medicine particles to rotate, so that the medicine particles that meet the size requirements are discharged from the screen hole 11 and fall on the roller groove 17 to be received, and finally roll onto the collection box 18 for collection. During this process, medicine particles that do not meet the size requirements may get stuck in the screen hole 11 and affect screening. At this time, when the slide rod 13 on the outer wall of the screening cylinder 3 rotates to the top, it will encounter the arc panel 16. At this time, the arc panel 16 will squeeze the roller 15 on the outer surface of the slide rod 13, causing the slide rod 13 to be compressed in the direction of the screening cylinder 3, so that the unblocking rod 14 on the slide rod 13 is inserted into the screen hole 11 to squeeze the medicine particles stuck in the screen hole 11 into the screening cylinder 3, thereby realizing the unblocking work and effectively ensuring that the screening cylinder 3 can continue to perform screening work.

[0025] Reference Figure 1 , 2 3. A track plate 19 is fixedly installed on the top right side of the support platform 1. A rack 20 is slidably installed on the front side of the track plate 19. A second gear ring 21, which is fixed to the rotating end of the right rotary joint 4, is meshed on the front side of the rack 20. A limiting movement groove adapted to the rack 20 is opened on the front side of the track plate 19. A lead screw 22 is threadedly connected to the rack 20. The rotation power of the lead screw 22 comes from the second drive motor fixedly installed at the bottom of the track plate 19. A collection cylinder 23 is placed on the right side of the support platform 1 below the discharge pipe 8.

[0026] With the above design, after the sieving cylinder 3 has been rotating for a period of time, if no medicine particles are discharged from the sieve holes 11 on the sieving cylinder 3 for a long time, it means that the sieving time is sufficient. At this time, the second motor is started to drive the lead screw 22 to rotate, so as to control the rack 20 to move upward, so that the rack 20 meshes with the second gear ring 21 and rotates 180 degrees. At this time, the right end of the discharge pipe 8 turns downward and faces the top of the collection cylinder 23. Finally, the high gear of the air pump 7 is started, while the sieving cylinder 3 is kept rotating. Under the large air volume injected by the air pump 7, the medicine particles in the sieving cylinder 3 that do not meet the size requirements are discharged into the collection cylinder 23 through the discharge pipe 8 for recycling, so as to finally complete the sorting of medicine particles.

[0027] The implementation principle of this application embodiment is as follows:

[0028] First, when using the sorting device to screen capsule granules, open the sealing cover on the feed tray 6 and pour the granules into the feed tray 6. Note that the amount of granules poured in should be such that it reaches the bottom of the screening cylinder 3 and is not higher than the horizontal level below the inner diameter of the rotating end of the rotary joint 4. Then, turn on the air pump 7 to inject air at a low setting. At this time, the injected air will blow the granules in the feed pipe 5 into the screening cylinder 3 to help the granules enter the screening cylinder 3 quickly. Since the initial position of the discharge pipe 8 is tilted upward on the right end, and the air pump 7 is injecting air at a low setting, the injected air will be discharged from the right end of the discharge pipe 8, while the granules in the screening cylinder 3 remain in the screening cylinder 3 and are constantly moved by the injected air.

[0029] Then, the No. 1 drive motor is started to drive the gear 10 to mesh with the No. 1 gear ring 9 to rotate. The rotation of the No. 1 gear ring 9 drives the sieve cylinder 3 to rotate together through the fixed end of the rotary joint 4. The rotation of the sieve cylinder 3 will continuously drive the internal drug particles to rotate, so that the drug particles that meet the size requirements are discharged from the sieve hole 11 and fall on the roller trough 17 to be received, and finally roll onto the collection box 18 for collection. During this process, drug particles that do not meet the size requirements may get stuck in the sieve hole 11 and affect the sieving. At this time, when the slide rod 13 on the outer wall of the sieve cylinder 3 rotates to the top, it will encounter the arc panel 16. At this time, the arc panel 16 will squeeze the roller 15 on the outer surface of the slide rod 13, causing the slide rod 13 to be compressed in the direction of the sieve cylinder 3, so that the unblocking rod 14 on the slide rod 13 can be inserted into the sieve hole 11 to squeeze the drug particles stuck in the sieve hole 11 into the sieve cylinder 3, so as to realize the unblocking work and effectively ensure that the sieve cylinder 3 can continue to perform sieving work.

[0030] After the sieving cylinder 3 has been rotating for a period of time, if no medicine particles are discharged from the sieve holes 11 on the sieve cylinder 3 for a long time, it means that the sieving time is sufficient. At this time, the second motor is started to drive the lead screw 22 to rotate, so as to control the rack 20 to move upward, so that the rack 20 meshes with the second gear ring 21 and rotates 180 degrees. At this time, the right end of the discharge pipe 8 turns downward and faces the top of the collection cylinder 23. Finally, the high gear of the air pump 7 is started, while the sieve cylinder 3 is kept rotating. Under the large air volume injected by the air pump 7, the medicine particles in the sieve cylinder 3 that do not meet the size requirements are discharged into the collection cylinder 23 through the discharge pipe 8 for recycling, so as to finally complete the sorting of medicine particles.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
