Description

Technical Field

[0001] The present invention relates to the technical field of capsule polishing, and specifically relates to a polishing device for sorting Xanthoceras sorbifolium capsules. Background Art

[0002] In the production process of Xanthoceras sorbifolium capsules, polishing is a crucial step. Polishing can not only improve the appearance quality of the capsules, making them smoother and brighter, but also effectively remove the defects and burrs on the surface of the capsules. Due to the quality problems such as internal empty shells, insufficient or excessive drug content in the manufacturing process of Xanthoceras sorbifolium capsules, if these unqualified capsules are not screened out in time, it will have a great impact on the subsequent production and use.

[0003] The patent with the publication number CN116787309B discloses a capsule polishing and sorting machine. When screening unqualified capsules, the capsules slide along the inclined polishing and sorting mechanism. When the capsules pass through the air passing plate, the upward airflow output by the first blower has a greater acting force on the unqualified capsules than the gravity of the unqualified capsules, causing the unqualified capsules to rise. The qualified capsules continue to move along the air passing plate and are discharged from the first qualified material outlet, while the unqualified capsules enter the blanking drawer after rising, realizing the screening of unqualified capsules.

[0004] Although the above solution realizes the screening of unqualified capsules, when the capsules are screened through the air passing plate, due to the different postures of the capsules, the acting forces of the first blower on each capsule may be different. At the same time, the airflow output by the first blower acts on the capsules through the ventilation holes, and there is no airflow in the gaps between the ventilation holes to provide an acting force on the capsules, and the number of ventilation holes covered by each capsule may be different, resulting in different force application points for each capsule. Therefore, the force conditions of each capsule are different, which may lead to incorrect screening results. Summary of the Invention

[0005] Aiming at the above problems, a polishing device for sorting Xanthoceras sorbifolium capsules is provided. By setting a feeding mechanism and a screening mechanism, the airflow released by the air separation structure passes through the gap between the first strip-shaped air outlet and the conveying unit, and uniformly blows the bottom of the capsules, which ensures that the upward acting force on each capsule is the same, thereby realizing the precise control of the screening posture and the acting force magnitude of the capsules, and effectively avoiding the mis-screening of unqualified capsules.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. The present invention is provided with a discharging mechanism and a screening mechanism. The transfer mechanism in the discharging mechanism moves the storage plate to one end of the adjacent conveying structure, realizing the docking of the capsules from the polishing box to the conveying structure, and the capsules in each storage cavity are distributed to the corresponding conveying structure, ensuring the orderliness and controllability of the capsules in the subsequent processing process. The capsules move along a straight path under the clamping of the two conveying units, ensuring the stability of the capsules during the conveying process. When the capsules move directly above the air separation structure, the airflow released by the air separation structure passes through the gap between the first strip-shaped air outlet and the conveying unit, and uniformly blows the bottom of the capsules, which ensures that the upward acting force received by each capsule is the same, thereby realizing the precise control of the screening posture and the acting force magnitude of the capsules, and effectively avoiding the mis-screening of unqualified capsules.

[0018] 2. The present invention is provided with a flipping structure and a discharge structure. The discharge structure closes the storage cavity on the storage plate to ensure that the capsules will not fall due to vibration during the operation of the flipping structure. Subsequently, the first linear drive applies a driving force to the first mounting frame to make the first mounting frame rotate smoothly around the hinge point with the polishing box. When the first mounting frame drives the storage plate to rotate to a horizontal state, the distance between each capsule on the storage plate and the corresponding conveying structure remains consistent. Then, multiple discharge structures are started at the same time to ensure that multiple capsules in the same group can fall onto the conveying structure at the same time under the action of gravity. Since the capsules on the storage plate remain equidistant during the flipping process and the discharge structure is opened synchronously, the equidistant arrangement of the capsules on the conveying structure is achieved, effectively avoiding mutual contact between the capsules.

[0019] 3. The present invention provides a third mounting frame, an air selection tube and a first blowing assembly. The second strip air outlet on the air selection tube is closely connected with the first strip air outlet on the conveying structure to form a continuous air flow channel. When the high-speed airflow flows from the second strip air outlet to the first strip air outlet, the airflow is shaped into a strip shape and blown directly and evenly toward the moving capsule, ensuring that all parts of the bottom of the capsule can receive uniform force from the airflow, thereby avoiding uncontrollable movement caused by uneven local force on the capsule.

Detailed implementation manners

[0034] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0035] Refer to Figures 1 to 13 As shown: A polishing device for sorting Xanthoceras sorbifolium capsules includes a base 1 and a polishing box 2 rotatably installed in the middle of the base 1, and a discharge port is provided at one end of the polishing box 2 close to the middle of the base 1. It also includes a feeding mechanism 3 and a screening mechanism 4; the feeding mechanism 3 includes a storage plate 31 and a transfer mechanism 32. The storage plate 31 is arranged at the discharge port of the polishing box 2. A number of groups of storage cavity groups 311 are provided on the storage plate 31, and each group of storage cavity groups 311 includes a number of storage cavities arranged in a straight line. The transfer mechanism 32 is arranged at the discharge port of the polishing box 2, and the transfer mechanism 32 is connected to the storage plate 31; the screening mechanism 4 is arranged beside the polishing box 2. The screening mechanism 4 includes a second installation frame 41, a number of conveying structures 42, a pneumatic separation structure 43 and a collection structure 44. The second installation frame 41 is horizontally arranged above the base 1. A number of conveying structures 42 are arranged on the second installation frame 41 at equal intervals, and a number of conveying structures 42 correspond to a number of groups of storage cavity groups 311 one by one. The conveying structure 42 includes a V-shaped frame 421 and two conveying units 422. A first strip-shaped air vent along the straight line direction of the storage cavity is opened in the middle of the V-shaped frame 421. The two conveying units 422 are respectively arranged on both sides of the first strip-shaped air vent. The conveying unit 422 includes two driving wheels 4221, a conveyor belt 4222 and a driving motor 4223. The two driving wheels 4221 are respectively arranged at both ends of the V-shaped frame 421. The conveyor belt 4222 is sleeved on the two driving wheels 4221. The driving motor 4223 is arranged at one end of the V-shaped frame 421, and the driving motor 4223 is connected to one of the driving wheels 4221. The pneumatic separation structure 43 is arranged at the lower end of the second installation frame 41, and the collection structure 44 is arranged at the upper end of the second installation frame 41.

[0036] First, after the Xanthoceras sorbifolium Bunge capsules complete the polishing operation in the polishing box 2, the polishing box 2 rotates about the rotation connection point between it and the base 1 until the discharge port of the polishing box 2 faces downward. At this time, some of the capsules inside the polishing box 2 fall into several groups of storage cavities preset on the storage plate 31 under the action of gravity. Subsequently, the polishing box 2 rotates to the horizontal position again. At this time, the remaining capsules in the polishing box 2 move away from the storage plate 31 due to gravity. Next, the transfer mechanism 32 is activated to transfer the storage plate 31 to the same end of several adjacent conveying structures 42. The capsules in each group of storage cavity groups 311 are distributed to the corresponding conveying structures 42. The capsules move along a straight path under the restriction of the two conveying units 422. When the capsules move directly above the air separation structure 43, the airflow released by the air separation structure 43 passes through the gap between the first strip-shaped air outlet and the two conveying units 422 to uniformly blow the bottom of the capsules. If the inside of the capsule is empty or the drug content is low, the lifting force generated by the airflow on the capsule will exceed its own gravity, causing the capsule to rise and separate from the conveying structure 42. At this time, the collection structure 44 captures the flying capsules to prevent the capsules from falling back onto the conveying structure 42. During the whole process, since the capsules pass through the air separation structure 43 in a consistent posture under the guidance of the conveying unit 422 and the airflow provided by the air separation structure 43 remains stable, it ensures that the upward acting force on each capsule is the same, thus achieving precise control over the screening posture and the magnitude of the force on the capsules, effectively avoiding the mis-screening of unqualified capsules.

[0037] Refer to Figure 3 and Figure 4 As shown: The transfer mechanism 32 includes a flipping structure 321 and a discharging structure 322; the flipping structure 321 includes a first mounting frame 3211 and a first linear driver 3212. One side of the first mounting frame 3211 is hinged to the polishing box 2. The storage plate 31 is installed inside the first mounting frame 3211. The first linear driver 3212 is arranged on one side of the first mounting frame 3211. The two ends of the first linear driver 3212 are respectively axially connected to the first mounting frame 3211 and the polishing box 2; there are several discharging structures 322. The several discharging structures 322 are arranged on the side of the storage plate 31 facing away from the polishing box 2, and the several discharging structures 322 respectively correspond to several groups of storage cavities. The discharging structure 322 includes two first partitions 3221, two rotating shafts 3222, and two first gears 3223. The two first partitions 3221 are respectively arranged on both sides of the storage cavity. The two rotating shafts 3222 are parallel to each other. The two ends of the rotating shaft 3222 are rotatably connected to the first mounting frame 3211. The two first partitions 3221 are respectively connected to the middle parts of the two rotating shafts 3222. The two first gears 3223 are respectively connected to the same ends of the two rotating shafts 3222, and the two first gears 3223 are meshed with each other.

[0038] During the process of transferring the capsules, first, the feeding structure 322 closes the storage cavities on the storage plate 31 to ensure that the capsules will not fall during the operation of the flipping structure 321. Subsequently, the first linear driver 3212 is activated to apply a driving force to the first mounting frame 3211 away from the polishing box 2, causing the first mounting frame 3211 to rotate around its hinge point with the polishing box 2. When the first mounting frame 3211 drives the storage plate 31 to rotate to a horizontal state, the distances between the capsules on the storage plate 31 and the corresponding conveying structures 42 are the same. At this time, multiple feeding structures 322 are activated simultaneously. Under the meshing action of the two first gears 3223, the two rotating shafts 3222 rotate in opposite directions, driving the two first partition plates 3221 to rotate to both sides and simultaneously opening multiple storage cavities. Multiple capsules in the same group fall onto the conveying structures 42 simultaneously under the action of gravity, thereby realizing the equidistant arrangement of the capsules on the conveying structures 42 and effectively avoiding the mutual contact between the capsules.

[0039] Refer to Figure 3 、 Figure 5 and Figure 7 As shown in: The air separation structure 43 includes a third mounting frame 431, a plurality of air separation pipes 432, and a first blowing component 433; the third mounting frame 431 is arranged on one side of the lower part of the second mounting frame 41; a plurality of air separation pipes 432 are arranged at equal intervals inside the third mounting frame 431, and a plurality of air separation pipes 432 respectively correspond to a plurality of conveying structures 42. A second strip-shaped air vent is opened on the surface of the air separation pipe 432 along its length direction, and the second strip-shaped air vent is communicated with the first strip-shaped air vent. A first air inlet is opened at one end of the air separation pipe 432; the first blowing component 433 is arranged beside the third mounting frame 431, and the first blowing component 433 is connected to a plurality of air separation pipes 432. The first blowing component 433 includes a first blowing pipe 4331 and a plurality of guide pipes 4332. The first blowing pipe 4331 is fixed on the first mounting frame 3211, and a plurality of guide pipes 4332 respectively correspond to a plurality of air separation pipes 432. Both ends of the guide pipe 4332 are communicated with the air separation pipe 432 and the first blowing pipe 4331 respectively.

[0040] Before the capsule enters the air selection structure 43, the first blowing component 433 is started, and the first blowing pipe 4331 in the first blowing component 433 provides a high-speed airflow, which is then distributed to a number of guide pipes 4332. Each guide pipe 4332 is connected to the corresponding air selection pipe 432 to ensure that the high-speed airflow can be evenly introduced into each air selection pipe 432. The air selection pipe 432 is provided with a second strip air outlet along its length. The second strip air outlet is connected with the first strip air outlet on the conveying structure 42 to form a continuous air flow channel. When the high-speed air flow flows from the second strip air outlet to the first strip air outlet, the air flow is shaped into a strip and blown directly onto the moving capsule, ensuring that each part of the bottom of the capsule can receive a uniform force from the air flow. The unqualified capsule therefore obtains a stable lifting force, thereby avoiding uncontrollable movement caused by uneven local force on the bottom of the capsule.

[0041] Reference Figure 3 and Figure 8 As shown: the collecting structure 44 includes a first cover body 441, which is covered on the upper ends of a plurality of conveying structures 42, and a plurality of strip-shaped feed openings are opened in the middle of the first cover body 441, which respectively correspond to a plurality of conveying structures 42, and the width of the strip-shaped feed openings is greater than the diameter of the capsule.

[0042] Since the bottom of the capsule is subjected to the stable force of the airflow, the capsule maintains stable movement for a period of time during the upward process, and the strip feed port on the first cover body 441 corresponds to the conveying structure 42, and the width of the strip feed port is greater than the diameter of the capsule. The capsule can pass through the strip feed port and move to the top of the first cover body 441 during the rising process. At this time, the force of the air selection structure 43 on the capsule gradually decreases until it disappears, and then the capsule falls to the upper end of the first cover body 441, thereby preventing the screened capsules from falling back onto the conveying structure 42.

[0043] Reference Figure 3 , Figure 5 and Figure 9 As shown: the collecting structure 44 also includes a second blowing component 442, and the second blowing component 442 includes a second cover body 4421 and a second blowing pipe 4422; the second cover body 4421 is covered on the upper end of the first cover body 441, and the two ends of the second cover body 4421 are respectively provided with a second air inlet and an exhaust port; the second blowing pipe 4422 is arranged at the second air inlet, and the second blowing pipe 4422 is connected to the inside of the second cover body 4421.

[0044] Under the action of the air selection structure 43, the capsule moves to the upper end of the first cover body 441. At this time, the second blowing assembly 442 is working, and the second blowing pipe 4422 provides a horizontal airflow to the interior of the second cover body 4421 and the space between the top of the first cover body 441. This airflow forms a vertical intersection with the vertical airflow provided by the air selection structure 43, forming a composite airflow field at the upper end of the first cover body 441. After reaching the upper end of the first cover body 441, the capsule is immediately affected by the horizontal airflow, causing the capsule to deviate from the original vertical rising path and shift toward one side of the strip feed port, so that the capsule is no longer located directly above the strip feed port, thereby preventing the capsule from falling back onto the conveying structure 42 from the strip feed port.

[0045] Reference Figure 9 and Figure 10 As shown, the collecting structure 44 also includes a plurality of baffle plates 443 , which correspond to a plurality of strip-shaped feed ports respectively, and the baffle plates 443 are arranged on one side of the strip-shaped feed ports close to the second blowing pipe 4422 , and ventilation slots are opened on the baffle plates 443 .

[0046] When the airflow provided by the second blowing component 442 blows the capsule to move, the capsule will detach from the previously corresponding strip feed port, but the capsule may move to the upper end of another strip feed port, causing the capsule to fall from the other strip feed port. By setting a baffle plate 443, the ventilation grooves on the baffle plate 443 can allow the airflow to flow directly above the strip feed port. When the airflow provided by the second blowing component 442 blows the capsule to move, the capsule stops moving after contacting the baffle plate 443, thereby preventing the capsule from falling from the remaining strip feed ports.

[0047] Reference Figure 10 As shown: the collecting structure 44 also includes a collecting assembly 444, the collecting assembly 444 includes a mounting plate 4441 and a plurality of U-shaped collecting tubes 4442; the mounting plate 4441 is arranged on one side of the second cover body 4421; the plurality of U-shaped collecting tubes 4442 respectively correspond to a plurality of strip-shaped feed ports, and the U-shaped collecting tube 4442 is arranged on a side of the strip-shaped feed port away from the second blowing tube 4422, and one end of the U-shaped collecting tube 4442 is fixedly connected to the mounting plate 4441.

[0048] The screened capsules fall on the first cover body 441, which is inconvenient to take out these capsules, so a collecting component 444 is provided, and several U-shaped collecting tubes 4442 in the collecting component 444 respectively correspond to several strip-shaped feed ports, and after the capsule contacts the baffle plate 443, the capsule will fall downward and fall into the U-shaped collecting tube 4442. After the capsule screening is completed, the mounting plate 4441 is pulled to pull out several U-shaped collecting tubes 4442 at the same time, thereby making the collection and removal process of unqualified capsules simple and efficient.

[0049] Refer to Figure 3 、 Figure 5 and Figure 11 As shown, the screening mechanism 4 further includes a lifting structure 45, and the lifting structure 45 includes a lifting drive structure 451 and four guiding structures 452; the lifting drive structure 451 is arranged on the base 1, and the lifting drive structure 451 is located in the middle of the second mounting frame 41 and is connected to the second mounting frame 41. The lifting drive structure 451 includes a double-headed screw rod 4511, two moving blocks 4512 and two drive plates 4513. The double-headed screw rod 4511 is horizontally installed on the base 1, and the two moving blocks 4512 are respectively connected to the two threaded portions of the double-headed screw rod 4511. The two drive plates 4513 respectively correspond to the two moving blocks 4512, and the two ends of the drive plate 4513 are respectively pivotally connected to the second mounting frame 41 and the moving block 4512; the four guiding structures 452 are respectively arranged at the four corners of the second mounting frame 41, and the two ends of the guiding structure 452 are respectively connected to the base 1 and the second mounting frame 41. The guiding structure 452 includes a guide sleeve 4521 and a second guide post 4522. The bottom of the guide sleeve 4521 is connected to the base 1, the second guide post 4522 is slidably arranged inside the guide sleeve 4521, and the top of the second guide post 4522 is connected to the second mounting frame 41.

[0050] When the polishing box 2 rotates, it will occupy a fixed range. To avoid collision between the polishing box 2 and the conveying structure 42 during rotation, the conveying structure 42 needs to be arranged outside the fixed range of the rotation of the polishing box 2. However, when the stock plate 31 is docked with the conveying structure 42, the height difference between the two is relatively large, and the gravity work time for the capsule to fall onto the conveying structure 42 is relatively long, resulting in the capsule jumping when it contacts the conveying structure 42. Therefore, the lifting structure 45 is provided. When the stock plate 31 moves to the horizontal state, the lifting structure 45 starts to work. The double-headed screw rod 4511 rotates, and the two moving blocks 4512 move away from each other accordingly, and apply an upward force to the second mounting frame 41 through the two drive plates 4513. At the same time, the second mounting frame 41 drives the second guide posts 4522 at its four corners to slide smoothly along their respective corresponding guide sleeves 4521, ensuring the smoothness and accuracy of the lifting process. As the second mounting frame 41 rises, the conveying structure 42 carried by the second mounting frame 41 also gradually moves towards the stock plate 31, thereby effectively reducing the distance between the stock plate 31 and the conveying structure 42.

[0051] Refer to Figure 4 and Figure 12As shown: The transfer mechanism 32 further includes a first driving structure 323. The first driving structure 323 is arranged on the same side of a plurality of feeding structures 322, and the first driving structure 323 is connected to the plurality of feeding structures 322. The first driving structure 323 includes a plurality of second gears 3231, a rack 3232, a second linear driver 3233, a first guide rod 3234 and a slider 3235. The plurality of second gears 3231 are respectively connected to one of the rotating shafts 3222 in the plurality of feeding structures 322. The rack 3232 meshes with all the plurality of second gears 3231. The second linear driver 3233 is arranged on one side of the rack 3232, and the output end of the second linear driver 3233 is connected to the rack 3232. The first guide rod 3234 is arranged along the length direction of the rack 3232. The slider 3235 is slidably arranged on the first guide rod 3234, and the slider 3235 is connected to the rack 3232.

[0052] When the storage plate 31 reaches the horizontal position, the second linear driver 3233 applies a pulling force in the horizontal direction to the rack 3232. This pulling force causes the rack 3232 to drive the slider 3235 to slide along the first guide rod 3234. Due to the cooperation between the slider 3235 and the first guide rod 3234, the movement of the rack 3232 is effectively restricted, ensuring that the rack 3232 can stably remain meshed with all the second gears 3231. During the movement of the rack 3232, the rack 3232 will synchronously drive all the second gears 3231 to rotate. These rotating second gears 3231 will in turn drive their respective corresponding feeding structures 322 to start working, thereby realizing that the storage cavities in different groups can simultaneously release the capsules.

[0053] Refer to Figure 3 and Figure 13 As shown: The feeding mechanism 3 further includes a partition structure 33. The partition structure 33 is arranged at the discharge port of the polishing box 2. The partition structure 33 includes a second partition plate 331 and a third linear driver 332. The second partition plate 331 is slidably connected to the polishing box 2. The third linear driver 332 is fixedly arranged on one side of the polishing box 2, and the third linear driver 332 is connected to the second partition plate 331.

[0054] During the process of the transfer mechanism 32 transferring the storage plate 31 to the horizontal position, the capsules in the polishing box 2 may fall from the discharge port due to the vibration. By providing the partition structure 33, when the polishing box 2 is transferred to the horizontal position, the third linear driver 332 drives the second partition plate 331 to insert into the discharge port of the polishing box 2 to completely close the discharge port. Then the transfer mechanism 32 drives the storage plate 31 to rotate towards the horizontal position, thereby preventing the capsules from falling from the discharge port of the polishing box 2.

[0055] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
