The transmission mechanism is equipped with a support mechanism for driving the capsule body and cap to complete the processing. Along the transmission direction of the transmission mechanism, a first feeding station, a second feeding station, a straightening station, a punching and injection station, a closing station, and a discharging station are sequentially arranged. This invention solves the technical problems of the capsule's internal pressure being higher than the external pressure due to air pressure buildup during the assembly of the cap and capsule body.

Description

Technical Field

[0001] This invention relates to the field of capsule technology, and in particular to a method and system for preparing blueberry lutein soft capsules. Background Technology

[0002] Capsules are generally used to contain powders or granules that are irritating to the esophagus and stomach lining, or medications that have an unpleasant taste, are volatile, are easily broken down by saliva in the mouth, or are easily inhaled into the trachea. Encapsulating these medications protects their efficacy from degradation and also protects the digestive and respiratory tracts. Removing the capsule shell may result in drug loss, waste, and reduced efficacy. Additionally, some medications need to dissolve and be absorbed in the intestines; capsules protect them from destruction by stomach acid. In pharmaceutical terms, capsules refer to encapsulated containers made of special film-forming materials (such as gelatin, cellulose, polysaccharides, etc.) to hold contents (such as powdered or liquid medications) or prescribed dosages for easy swallowing.

[0003] Patent document CN213526488U discloses a hollow capsule, comprising a capsule body, a first rib, a capsule cap, a second rib, a floating point, a vent, a retaining ring groove, a spiral protrusion, a spiral groove, a floating point groove, a retaining ring strip, and a retaining strip. The capsule body is provided with a first rib at equal intervals on its outer side, and the capsule cap is also provided with a second rib at equal intervals on its outer side. A retaining ring groove is provided on the capsule body on one side of the first rib, and the retaining ring groove cooperates with the retaining ring strip provided at the corresponding position on the inner wall of the capsule cap.

[0004] However, in actual use, the inventors found that when the cap and capsule are assembled by machine, the air pressure inside the capsule is higher than the external air pressure due to the accumulation of air. Furthermore, the existing cap and capsule are mostly assembled by pressing and closing with protrusions to increase friction. Under the condition of high internal air pressure, the capsule is prone to breaking open, loosening and separating during transmission, and young children may easily open it and swallow it. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Through a processing mechanism and an exhaust mechanism, the processing mechanism first creates ventilation holes at corresponding positions on the cap and the capsule body. Then, when the cap and capsule body are fastened together, the exhaust mechanism uses an air extraction tube aligned with the ventilation holes to quickly expel excess air from inside the capsule. The cap is then rotated to close the capsule, ensuring that the internal air pressure is slightly lower than the external air pressure, thus guaranteeing the stability of the capsule and facilitating transport and storage. Simultaneously, the slots on the cap and the protruding edges on the capsule body differentiate the capsule's opening method from simple pulling, preventing children from easily opening it. This solves the technical problems of air pressure buildup during machine assembly of the cap and capsule body, resulting in higher internal air pressure than external air pressure. Furthermore, existing methods often use pressing to close the cap and capsule body, increasing friction through protrusions, which can easily lead to the capsule bursting, loosening, or children accidentally opening and ingesting the contents during transport when the internal air pressure is high.

[0028] A method for adapting a blueberry lutein soft capsule preparation system includes the following steps:

[0029] Step 1, Cap and Cap Assembly Process: First, at the first loading station, the capsules that have been arranged on the arrangement assembly are taken out by the tensioning and transfer components and placed into the first holding assembly on the carrying mechanism. During the process, the auxiliary components converge the multiple outward protruding edges of the capsules arranged in a ring. Then, driven by the transmission mechanism, the carrying mechanism moves to the second loading station. In the second loading mechanism, the upper cap is placed into the second holding assembly under the combined action of the screening and loading components. During the process, the upper cap is sucked tight by the negative pressure component to prevent it from falling off.

[0030] Step two, inspection process: Next, at the correction station, the upper cap is rotated by the locking assembly so that the outer protruding edge of the bladder body is engaged with the groove on the inner wall of the upper cap. Then, the position of the bladder body is fixed by the locking assembly and the engagement of the bladder body and the upper cap is released, so as to ensure that the engagement between the upper cap and the bladder body is tight after the subsequent work is completed.

[0031] Step 3, filling and closing process: As the carrying mechanism moves to the punching and injection station, the processing mechanism opens vent holes on the capsule and the upper cap and injects powder into the capsule. Then, at the closing station, the exhaust mechanism helps the capsule to expel the air accumulated inside the capsule when the upper cap and capsule are closed. Finally, the capsule and the upper cap are assembled.

[0032] Step four, the unloading process: After processing, the capsules are unsecured by the locking components and the negative pressure components at the unloading station, and then the capsules are discharged.

[0033] The beneficial effects of this invention are:

[0034] (1) In this invention, by setting up a processing mechanism and an exhaust mechanism, the processing mechanism first opens vent holes at corresponding positions on the upper cap and the capsule body respectively. Then, when the upper cap and the capsule body are fastened together, the exhaust pipe in the exhaust mechanism is aligned with the vent holes to expel excess air from the capsule as soon as possible. Then, the upper cap is rotated to close it with the capsule body, so that the air pressure inside the capsule is slightly lower than the external air pressure, thereby ensuring the stability of the capsule state, which is beneficial for transmission and preservation. At the same time, the slot set on the upper cap and the protruding edge set on the capsule body make the capsule opening method different from simple pulling, preventing children from opening it easily. This solves the technical problem that when the upper cap and the capsule body are assembled by machine, the air pressure inside the capsule is higher than the external air pressure. Moreover, the existing upper cap and capsule body are mostly assembled by pressing and closing and increasing friction by protrusion. Under the condition of high air pressure inside the capsule, it is easy to break open, loosen and separate, and children can easily open and swallow it.

[0035] (2) In this invention, by setting an auxiliary component, the auxiliary component includes multiple sets of extrusion frames arranged in a circle along the first placement groove, a first telescopic component connected to one side of the extrusion frame and connected to the bottom plate, a stop bar connected to one side of the extrusion frame, and multiple first trigger blocks connected to the bottom of the top plate. Since the outer protrusion edge set on the outside of the capsule causes a certain obstruction when the cap falls, with the help of the auxiliary component, the outer protrusion edge will converge under the action of the auxiliary component before the cap falls. When the cap slides on the upper edge of the outer protrusion edge, the auxiliary component gradually releases the fixing effect on the outer protrusion edge. Slowly, the cap can completely cover the outside of the capsule, which is convenient for the assembly work and solves the technical problem that the capsule structure is not easy to assemble.

[0036] (3) In this invention, by setting up a negative pressure component, a locking component, a buckle component, a first holding component and a second holding component, the working state of each component is continuously adjusted during the processing, and they cooperate with each other to achieve precise control of the cap and the bladder, making the processing and discharging process more convenient and faster, and the operation more precise, thereby improving the automation level of the device and saving labor costs.

[0037] (4) In this invention, by sequentially setting the capsule body, the cap loading process, the detection process, the filling and closing process, and the discharge process, after the cap and capsule body complete the loading process, the cap first drives the capsule body to rotate several times to detect the closure between the cap and capsule body, and determine the relative position between the outer convex edge and the slot. This is so that after the powder injection is completed in the filling and closing process, multiple caps can be rotated at a specified angle to ensure that all caps and capsule bodies are perfectly closed, thereby enhancing the stability of the capsule state and solving the technical problem of insufficient closure between the cap and capsule body, which is prone to loosening during transmission.

[0038] In summary, this device has the advantages of simple and ingenious structure, high bonding strength and difficulty in separation, and is especially suitable for the field of capsule technology. Attached Figure Description

[0067] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0068] Example 1

[0069] like Figure 1-3 As shown, a blueberry lutein soft capsule preparation system includes a frame and a transfer mechanism 1 disposed on the frame;

[0070] The transmission mechanism 1 is provided with a bearing mechanism 2 for driving the bag body 100 and the upper cap 200 to complete the processing work;

[0071] Along the transmission direction of the transmission mechanism 1, there are sequentially arranged a first feeding station, a second feeding station, a straightening station, a drilling and injection station, a closing station, and a discharge station;

[0072] The first feeding station is equipped with a first feeding mechanism 3 for placing the capsule 100 on the support mechanism 2; the second feeding station is equipped with a second feeding mechanism 4 for placing the cap 200 on the support mechanism 2; the straightening station is equipped with a straightening mechanism 5 for adjusting the splicing position of the cap 200 slot 500 and the outer protruding edge 400 of the capsule 100; the punching and filling station is equipped with a processing mechanism 6 for opening vent holes 300 on the cap 200 and the capsule 100 and completing the filling work; the closing station is equipped with an exhaust mechanism 7 for venting excess air from the capsule; and the discharging station is equipped with a discharging mechanism 8 for removing the processed capsule.

[0073] The supporting mechanism 2 includes a first holding component 21 disposed on the transmission mechanism 1 for holding the capsule 100, a second holding component 22 disposed on the first holding component 21 for holding the cap 200, an auxiliary component 23 disposed on the first holding component 21 for assisting the convergence of multiple annularly arranged protruding edges 400 on the capsule 100, a locking component 24 disposed on the first holding component 21 for clamping the capsule 100 to prevent it from rotating, a locking component 25 disposed on the second holding component 22 for driving the cap 200 to rotate so that the protruding edges 400 on the capsule 100 engage with the slots 500 on the inner wall of the cap 200, and a negative pressure component 26 disposed on the second holding component 22 for strengthening the fixation of the cap 200.

[0074] In this embodiment, by setting up a carrying mechanism 2 in conjunction with a first feeding mechanism 3, a second feeding mechanism 4, a straightening mechanism 5, a processing mechanism 6, and an exhaust mechanism 7, the carrying mechanism 2 includes a first holding component 21 disposed on the transmission mechanism 1 for holding the capsule 100, a second holding component 22 disposed on the first holding component 21 for holding the cap 200, an auxiliary component 23 disposed on the first holding component 21 for assisting the convergence of the plurality of annularly arranged protruding edges 400 on the capsule 100, a locking component 24 disposed on the first holding component 21 for clamping the capsule 100 to prevent it from rotating, and a component disposed on the second holding component 22 for driving the cap 200 to rotate. The locking assembly 25, which connects the outer protruding edge 400 of the capsule body 100 with the slot 500 on the inner wall of the cap 200, and the negative pressure assembly 26, which is set on the second holding assembly 22 and used to strengthen the fixation of the cap 200, are used to facilitate the processing and shaping of the capsule. After the capsule body 100 and the cap 200 are successively installed on the carrying mechanism 2 under the action of the first feeding mechanism 3 and the second feeding mechanism 4, the carrying mechanism 2 continuously changes its working state as needed through the negative pressure assembly 26, the locking assembly 24 and the auxiliary assembly 23 during the operation of the straightening mechanism 5, the processing mechanism 6 and the exhaust mechanism 7, thereby facilitating the processing and shaping of the capsule and reducing the possibility of excessive internal air pressure and insufficient closure of the capsule during the processing.

[0075] In detail, firstly, at the first loading station, the pre-arranged capsules 100 on the arrangement assembly 31 are removed by the tensioning assembly 33 and the transfer assembly 32 and placed into the first holding assembly 21 on the carrying mechanism 2. During this process, the auxiliary assembly 23 converges the multiple annularly arranged protruding edges 400 on the capsules 100. Then, driven by the transmission mechanism 1, the carrying mechanism 2 moves to the second loading station. In the second loading mechanism 4, the upper cap 200 is placed into the second holding assembly 22 under the combined action of the screening assembly 41 and the upper assembly 42. During this process, the negative pressure assembly 26 sucks the upper cap 200 to prevent it from falling off. Next, at the straightening station, the locking assembly 25 drives the upper cap 200 to rotate, causing the protruding edges 400 on the capsules 100 to contact the inner wall of the upper cap 200. The card slot 500 is assembled, and then the position of the capsule 100 is fixed by the locking component 24 before the assembly of the capsule 100 and the upper cap 200 is released, thus ensuring a tight fit between the upper cap 200 and the capsule 100 after subsequent work is completed. As the carrying mechanism 2 moves to the punching and filling station, the processing mechanism 6 opens the vent holes 300 on the capsule 100 and the upper cap 200 and injects the powder into the capsule 100. Then, at the closing station, the exhaust mechanism 7 helps the capsule to expel the air accumulated inside the capsule when the upper cap 200 and the capsule 100 are closed. Then, the capsule 100 and the upper cap 200 are assembled. After the processing is completed, the locking component 24 and the negative pressure component 26 are released from the capsule 100 and the upper cap 200 at the discharge station, and then the capsule is discharged.

[0076] It should be noted that the multiple protruding edges 400 arranged in a ring on the capsule 100 and the slots 500 on the inner wall of the cap 200 that cooperate with the protruding edges 400 are all finished products formed after casting.

[0077] Furthermore, such as Figure 3-4 As shown, the first holding component 21 includes a base plate 212 connected to the transmission mechanism 1 via a guide block 211 and a plurality of first placement slots 213 opening on the top of the base plate 212;

[0078] The second holding assembly 22 includes a first driving cylinder 222 connected vertically to the base plate 212 via a mounting bracket 221, a top plate 223 connected to the output end of the first driving cylinder 222, and a plurality of second placement slots 224 opened on the top plate 223 and corresponding to the first placement slot 213.

[0079] The auxiliary component 23 includes multiple sets of extrusion frames 231 arranged circumferentially along the first placement groove 213, a first telescopic member 232 connected to one side of the extrusion frame 231 and connected to the bottom plate 212, a stop bar 233 connected to one side of the extrusion frame 231, and multiple first trigger blocks 234 connected to the bottom of the top plate 223.

[0080] The locking assembly 24 includes multiple sets of restraint frames 241 arranged on both sides of the first placement slot 213, two first racks 242 respectively connected to the corresponding restraint frames 241 and arranged in a centrally symmetrical manner, and a first gear 243 connected to the base plate 212 and meshing with the two first racks 242 for transmission.

[0081] In this embodiment, by setting the first placement groove 213 and the second placement groove 224 in the first holding component 21 and the second holding component 22, the capsule 100 and the cap 200 can be initially fixed. Since the outer protruding edge 400 of the capsule 100 causes a certain obstruction when the cap 200 falls, the outer protruding edge 400 will converge under the action of the auxiliary component 23 before the cap 200 falls. When the cap 200 slides on the upper edge of the outer protruding edge 400, the auxiliary component 23 gradually releases the fixing effect on the outer protruding edge 400. Slowly, the cap 200 can completely cover the outside of the capsule 100, which is convenient for the assembly work. Then, the locking component 24 helps to lock the capsule 100 in the corrected position, which facilitates the final assembly work, ensures the accuracy of the assembly, and reduces the occurrence of insufficient capsule sealing.

[0082] It should be noted that the first placement groove 213 and the second placement groove 224 have a certain friction on the bladder 100 and the upper cap 200 respectively. Under the action of external force, the bladder 100 and the upper cap 200 can still rotate. The binding frame 241 in the locking assembly 24 is provided with an adhesive surface, which can provide a large friction force when fixing the bladder 100 to prevent the bladder 100 from being driven by the outside and thus rotating.

[0083] Furthermore, such as Figure 5-6 As shown, the locking assembly 25 includes a plurality of second gears 251 connected to the bottom of the top plate 223 and corresponding to the second placement groove 224, a fixing hole 252 opened on the second gears 251 and coaxially arranged with the second placement groove 224, a plurality of third gears 253 interleaved between the second gears 251, and a fourth gear 255 connected to the third gears 253 by a connecting rod 254;

[0084] The negative pressure assembly 26 includes a negative pressure chamber 261 opened inside the top plate 223 and connected to a plurality of second placement slots 224, a piston plate 262 connected inside the negative pressure chamber 261, a connecting plate 264 connected to the piston plate 262 via a second telescopic member 263, and a first trapezoidal block 265 connected to one side of the top plate 223 for driving the connecting plate 264 to extend and retract.

[0085] In this embodiment, by setting a locking assembly 25 and a negative pressure assembly 26, the negative pressure assembly 26 ensures that the cap 200 does not detach from the second placement groove 224 during the processing, and the locking assembly 25 drives the cap 200 to rotate, thereby completing the locking and splicing between the cap 200 and the bladder body 100.

[0086] It should be noted that a flexible pad is provided at the connection position between the second placement slot 224 and the negative pressure chamber 261, so that the upper cap 200 is in close contact with the flexible pad, and thus no air leakage will occur during the rotation of the upper cap 200.

[0087] Furthermore, such as Figure 7-12 As shown, the first feeding mechanism 3 includes an arrangement component 31 disposed on one side of the transmission mechanism 1 for arranging the capsules 100, a transfer component 32 disposed above the arrangement component 31 for transferring the capsules 100, and a tensioning component 33 disposed on the transfer component 32 for tightening the inside of the capsules 100 to facilitate transfer.

[0088] The arrangement assembly 31 includes a first motor 313 connected to one side of the cylinder 311 and with a cross plate 312 connected to its output end, a recovery frame 314 connected to one side of the cylinder 311 and used for recovering the bladder 100, an arrangement plate 316 connected to the recovery frame 314 by a first spring 315 and with one end connected to the outlet of the cylinder 311, a plurality of discharge holes 317 opened on the arrangement plate 316, and an L-shaped rod 318 connected to the bottom of the arrangement plate 316 and used to cooperate with the cross plate 312 to drive the arrangement plate 316 to vibrate.

[0089] The transfer assembly 32 includes a limiting groove 322 formed on the vertical plate 321, a swing rod 324 connected to the vertical plate 321 via a rotating slide block 323, a second motor 326 connected to the vertical plate 321 and whose output end drives the swing rod 324 to move in the limiting groove 322 via a first waist-shaped groove plate 325, a mounting plate 327 connected to the end of the swing rod 324, and a plurality of second trigger blocks 328 connected to the bottom of the mounting plate 327 and used to push the stop bar 233;

[0090] The tensioning assembly 33 includes multiple circular plates 332 connected to the bottom of the mounting plate 327 via a first rotating shaft 331 and corresponding to the first placement groove 213; multiple drive grooves 333 formed on the circular plates 332 in an annular arrangement; multiple arc-shaped plates 335 connected to the bottom of the mounting plate 327 and connected to the drive grooves 333 via drive rods 334; sector gears 336 connected to the first rotating shaft 331; double-sided racks 337 connected to the mounting plate 327 and meshing with the multiple sector gears 336; reset holes 338 on the double-sided racks 337; and a second trapezoidal block 339 and a reset frame 3310 respectively connected to the recycling rack 314 and the frame for driving the double-sided racks 337.

[0091] In this embodiment, multiple bladders 100 are arranged neatly by setting the arrangement component 31 in the first feeding mechanism 3, and then the bladders 100 are transferred and placed in the first placement slot 213 in the bearing mechanism 2 by the transfer component 32 and the tensioning component 33. The arrangement plate 316 converts the power into its own vibration through the first spring 315 and the L-shaped rod 318, thereby accelerating the arrangement efficiency.

[0092] In detail, the arranging assembly 31 first starts working under the drive of the first motor 313. The first motor 313 drives the cross plate 312 to rotate, and the cross plate 312 rolls up the capsule 100 and places it on the arranging plate 316. During the process, the cross plate 312 continuously presses down on the L-shaped rod 318, thereby driving the arranging plate 316 to move downwards in the vertical direction. As the cross plate 312 releases its pressure on the L-shaped rod 318, the first spring 315 drives the arranging plate 316 to return to its original position through its elastic force. This process is repeated, causing the arranging plate 316 to vibrate. At this time, some of the falling capsules 100 are stuck in the discharge hole 317, while others are not. The capsule 100 in the discharge hole 317 rolls down into the cylinder 311 along the inclined recycling rack 314 for further screening. When the carrying mechanism 2 is in place, the second motor 326 in the transfer assembly 32 first drives the first waist-shaped groove plate 325 to rotate. The first waist-shaped groove plate 325 then drives one end of the swing rod 324 to move in the limiting groove 322. Next, the swing rod 324 drives the mounting plate 327 to move towards the capsule 100 and inserts the arc plate 335 into the interior of the capsule 100. As the swing rod 324 drives the mounting plate 327 to move, the double-sided rack 337 set on the mounting plate 327 and the connecting... The second trapezoidal block 339 attached to the recycling rack 314 contacts and squeezes, causing the double-sided rack 337 to move and drive multiple meshing sector gears 336 to rotate. The sector gears 336 drive the circular plate 332 to rotate via the first rotating shaft 331. Subsequently, the circular plate 332 unfolds multiple arc-shaped plates 335 outward through the opened drive groove 333 and drive rod 334, so that the arc-shaped plates 335 are fixed from inside the bladder 100. Next, the second motor 326 reverses again to drive the bladder 100 and move it above the first placement groove 213. As the mounting plate 327 falls, the bladder 100 first enters multiple extrusion... Between the pressure frames 231, and at this time, the reset holes 338 on the double-sided racks 337 contact and press with the reset frame 3310 set on the frame, causing the tensioning assembly 33 to reset. The bladder 100 is placed in the first placement slot 213. During the process, multiple second trigger blocks 328 move down with the mounting plate 327 and contact and press with the stop bar 233 on one side of the pressure frame 231, causing multiple pressure frames 231 to spread out. When the transfer assembly 32 is reset, with the elastic force of the first telescopic member 232, multiple pressure frames 231 are reset and the outer protruding edge 400 set on the outside of the bladder 100 is pressed and converged, which facilitates subsequent assembly work.

[0093] It should be noted that when the capsule 100 vibrates on the arrangement plate 316, it will fall into the discharge hole 317, and then slide down under the action of gravity to the position where the outer protrusion 400 and the discharge hole 317 are blocked. At this time, because the capsule 100 is relatively long, it is not easy to be ejected during subsequent vibrations. The capsule processing in this application is exemplified by a 2×2 method, which can be changed according to the customer's production needs in specific use. Due to the combined action of the limiting groove 322 and the rotating slide 323, the swing rod 324 can complete the work of rotating a specified angle and then extending and retracting.

[0094] Furthermore, such as Figure 13-14 As shown, the second feeding mechanism 4 includes a screening component 41 disposed on one side of the frame and used to drive the upper cap 200 to move and complete the falling screening work, and an upper assembly component 42 disposed on one side of the screening component 41 and used to receive the upper cap 200 and drive the upper cap 200 to be installed on the top plate 223.

[0095] The screening assembly 41 includes a drop channel 412 connected to the top of the screening box 411, a belt conveyor 413 connected inside the screening box 411 and used to transport the upper cap 200 to the drop channel 412, and a conveyor plate 414 disposed on the belt conveyor 413.

[0096] The upper assembly 42 includes a lifting platform 422 connected to the output end of the second drive cylinder 421, a third motor 424 connected to the lifting platform 422 and whose output end is connected to a tilting frame 423, a screening rack 426 connected to the tilting frame 423 via a second rotating shaft 425 and cooperating with the falling channel 412 to collect the cap 200, a counterweight ball 427 connected to the screening rack 426, and a push rod 428 connected to the lifting platform 422.

[0097] In this embodiment, the upper cap 200 is installed on the screening rack 426 by setting the screening component 41. Then, the counterweight ball 427 ensures that the screening rack 426 remains vertical when it is reversed, which facilitates the installation of the upper cap 200. At the same time, the negative pressure component 26 is driven to work during the installation process to suck up the upper cap 200 and prevent it from falling off.

[0098] In detail, when the carrying mechanism 2 reaches the second loading station driven by the transmission mechanism 1, the upper assembly 42 starts to operate and installs the upper cap 200 on the second holding assembly 22. Before this, multiple upper caps 200 are conveyed to the falling channel 412 by the belt conveyor 413 set in the screening box 411 in the screening assembly 411, and then fall onto the screening frame 426 through the falling channel 412. The upper cap 200 with the appropriate angle is fastened to the protruding part on the screening frame 426 for easy subsequent installation. When the third motor 424 drives the tilting frame 423 to rotate, it drives the screening frame 426 to move through the second rotating shaft 425. The counterweight ball 427 set on the screening frame 426 keeps the screening frame 426 always vertical. In the downward position, when the upper cap 200 is moved to below the second holding component 22, the second drive cylinder 421 drives the lifting platform 422 to move upward, thereby causing the upper cap 200 to be inserted into the second placement slot 224. At the same time, the lifting platform 422 drives the push rod 428 on one side to push the first trapezoidal block 265 on one side of the top plate 223 to move upward. Then, the first trapezoidal block 265 pulls the connecting plate 264 outward through the inclined surface, thereby driving the piston plate 262 in the negative pressure chamber 261 to move through the second telescopic member 263. Since the outer wall of the upper cap 200 is attached to the inner wall of the second placement slot 224 before reaching the top, it blocks the air from entering, thereby reducing the air pressure inside the negative pressure chamber 261, which strengthens the fixation of the upper cap 200.

[0099] Furthermore, such as Figure 15-18 As shown, the correction mechanism 5 includes a first drive rack 51, a second drive rack 52, and a third drive rack 53 sequentially arranged on the frame along the transmission direction of the bearing mechanism 2. The first drive rack 51 is used to mesh with the second gear 251 to drive the upper cap 200 to rotate and engage with the bladder body 100. The second drive rack 52 is used to drive the first gear 243 to rotate, thereby driving the restraint frame 241 to fix the bladder body 100 to prevent it from rotating. The third drive rack 53 is used to drive the fourth gear 255 to rotate, thereby driving the upper cap 200 to reverse and separate from the bladder body 100.

[0100] In this embodiment, by setting a correction mechanism 5, before drilling holes in the upper cap 200 and the bladder 100 and before the filling process, the positions of the upper cap 200 slot 500 and the outer protruding edge 400 of the bladder 100 are first determined. Then, when the subsequent processing is completed, the multiple upper caps 200 and multiple bladders 100 can be locked together by rotating them at a specified angle, preventing separation during transportation due to improper assembly.

[0101] In detail, after the cap 200 and the bladder body 100 are both installed, the carrying mechanism 2 is transferred to the straightening station. At the straightening station, the first drive cylinder 222 first drives the top plate 223 to move downward through the output end, so that the cap 200 is fastened onto the bladder body 100. During the process, before the cap 200 falls, the outer protruding edge 400 will converge under the action of the squeezing frame 231 in the auxiliary component 23. When the cap 200 continues to fall and slides against the upper edge of the outer protruding edge 400, multiple first trigger blocks connected to the bottom of the top plate 223 trigger the upper edge of the bladder body 100. 234 drives the extrusion frame 231 to gradually release the fixing effect on the outer protrusion 400, and slowly the cap 200 can completely cover the outside of the capsule 100 and fall to the designated position, ready for the correction work; during the correction work, the bearing mechanism 2 needs to move continuously and pass through the first drive rack 51, the second drive rack 52 and the third drive rack 53 set on the frame. When the first drive rack 51 and the second gear 251 mesh, the second gear 251 is driven by multiple interleaved gears. The third gear 253 drives all the second gears 251 to rotate. The second gears 251, through the friction between the inner wall of the fixing hole 252 at the center and the edge of the upper cap 200, cause the upper cap 200 to rotate several times. This causes the outer protruding edge 400 of the outer wall of the bladder 100 to engage with the slot 500 inside the upper cap 200, completing the assembly. Subsequently, the second drive rack 52 meshes with the first gear 243, and the first gear 243 drives the first racks 242 on both sides to retract, thereby driving the restraint frames 24 on both sides of the bladder 100. 1. The two sides of the bladder body 100 are clamped to prevent it from rotating when the upper cap 200 rotates. Next, the third drive rack 53 meshes with the fourth gear 255 for transmission. The fourth gear 255 drives the third gear 253 to rotate through the connecting rod 254, and at the same time drives multiple second gears 251 to reverse, thereby driving the upper cap 200 to reverse so that the outer protruding edge 400 separates from the bladder body 100 slot 500. Then, under the action of the first drive cylinder 222, the top plate 223 and the upper cap 200 move upward to a certain height to facilitate the subsequent drilling work.

[0102] It should be noted that due to the randomness of the position and angle between the capsule 100 and the upper cap 200, the second gear 251, driven by the longer first drive rack 51, will cause the upper cap 200 to rotate several times, thus ensuring that the outer protruding edge 400 of the outer wall of each capsule 100 is completely engaged in the slot 500 inside the upper cap 200. During this process, when the upper cap 200 rotates, because the friction between it and the capsule 100 is less than the friction between the inner wall of the first placement groove 213 and the outer wall of the capsule 100, the upper cap 200 will not be able to drive the capsule 100 to rotate. When the cap 200 engages with the capsule body 100, the frictional force of the bottom first placement groove 213 on the outer wall of the capsule body 100 is less than the rigid force after the cap 200 engages with the capsule body 100, causing the cap 200 to rotate together with the capsule body 100, and making the outer protruding edge 400 and the groove 500 more tightly fastened. When the cap 200 and the capsule body 100 are disengaged by rotation, the angle of rotation at this time is the angle of rotation required when reassembling after completing the drilling and filling work. Therefore, it can ensure that the quality of capsule assembly after processing is guaranteed.

[0103] Furthermore, such as Figure 19-21 As shown, the processing mechanism 6 includes a support frame 61 connected to the frame, multiple slide rails 62 arranged on the support frame 61, a punching frame 64 connected to the slide rails 62 via a first slider 63, a push block 66 connected to the first slider 63 via a connecting rod 65 and connected to the support frame 61, a needle plate 68 connected to one side of the push block 66 via a third telescopic member 67 and used to open ventilation holes 300 on the upper cap 200 and the bladder 100, a connecting frame 610 connected to the output end of the third drive cylinder 69 and connected to the multiple needle plates 68, a storage box 611 connected to one side of the support frame 61, and multiple discharge pipes 612 corresponding to the first placement slot 213 and communicating with the storage box 611.

[0104] In this embodiment, the processing mechanism 6 is set to facilitate the drilling and filling work. At the same time, the first slider 63, slide rail 62, connecting rod 65 and push block 66 ensure that the drilling position is fixed, so that the cap 200 and the vent hole 300 on the bladder 100 can correspond during subsequent assembly.

[0105] In detail, when the bearing mechanism 2 reaches the punching and injection station, the top plate 223 and the bottom plate 212 stop above and below the processing mechanism 6, respectively. Then, the output end of the third drive cylinder 69 drives multiple needle plates 68 to move through the connecting frame 610. During the process, the needle plates 68 push the push block 66 to move through the third telescopic member 67. The push block 66 pushes the first slider 63 to move on the slide rail 62 through the connecting rod 65. Finally, the connecting rod 65 is pushed to the vertical state. At this time, the punching frame 64 moves to the designated position with the first slider 63. Then, the needle plates 68 continue to move, causing the third telescopic member 67 to begin to retract. The protruding part of the needle plate 68 cooperates with the punching frame 64 to complete the extrusion punching. Then, the third drive cylinder 69 drives the processing mechanism 6 to reset and injects powder into multiple capsules 100 through the storage box 611 and the discharge pipe 612.

[0106] It should be noted that the extrusion cutting method makes the punched area smoother and will not affect subsequent operations. The punching waste will be collected in the punching frame 64. The height of the injected powder does not exceed the punched position on the capsule 100. The first telescopic component 232, the second telescopic component 263 and the third telescopic component 67 are all composed of telescopic springs and round rods.

[0107] Furthermore, such as Figure 2 and Figure 22-23 As shown, the exhaust mechanism 7 includes a long plate 71 with an L-shaped groove 70, an exhaust pipe 74 connected to the L-shaped groove 70 via a second slider 72 and connected at one end to an exhaust fan 73, a first directional gear 75 connected to the exhaust pipe 74, a first directional rack 76 connected to the long plate 71 and meshing with the first directional gear 75 to drive the exhaust pipe 74 to rotate, a second waist-shaped groove plate 78 connected to the output end of the fourth drive cylinder 77 and used to push the exhaust pipe 74 to move, and a fourth drive rack 79 connected to the frame and meshing with the second gear 251.

[0108] It is worth mentioning that the exhaust mechanism 7 allows the gas squeezed inside the bag 100 to be discharged when the cap 200 is closed, thereby preventing the bag from collapsing during transmission due to high internal pressure.

[0109] In detail, when the carrying mechanism 2 moves to the closed position, the auxiliary component 23 opens under the action of the first drive cylinder 222 and drives the upper cap 200 to engage with the capsule 100, aligning the two vent holes 300. Then, the output end of the fourth drive cylinder 77 pushes the second waist-shaped groove plate 78 to move. Subsequently, under the combined action of the second waist-shaped groove plate 78 and the L-shaped slide 70, the suction pipe 74 moves along the path of the L-shaped slide 70, driving the second slider 72 to move. During the process, the first directional gear 75 connected to the suction pipe 74 meshes with the first directional rack 76 connected to the long plate 71, thereby driving the suction pipe 74 to rotate 90°. Then, it passes through the edge of the vent hole 300 and sucks out the air inside the capsule through the suction machine 73. Then, the carrying mechanism 2 continues to move forward and immediately drives the second gear 251 to mesh with the fourth drive rack 79 on the frame, thereby driving the outer protrusion 400 to engage with the slot 500.

[0110] It should be noted that by quickly locking the cap 200 and the capsule body 100 together while venting, the air pressure inside the capsule is slightly lower, which helps to ensure the stability of the capsule in the closed state.

[0111] Example 2

[0112] like Figure 2 and Figure 24-26 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0113] Furthermore, such as Figure 1 and Figure 24-26 As shown, the discharge mechanism 8 includes a third trapezoidal block 81 connected to the frame and used to drive the first trapezoidal block 265 to release the connection plate 264; a fifth drive rack 82 connected to the frame and meshing with the first gear 243; multiple through holes 83 opened on the bottom plate 212 and corresponding to the first placement groove 213; a guide rod 85 connected to the output end of the fifth drive cylinder 84 and used to pass through the through holes 83 to remove the capsule; a gripping frame 87 set on the frame and connected to the second directional gear 86; a second directional rack 88 connected to the bottom plate 212 and meshing with the second directional gear 86; a release frame 811 connected to the frame by the second spring 89 and connected at one end to the fourth trapezoidal block 810; and a collection box 812 set below the release frame 811. The fourth trapezoidal block 810 is used to cooperate with the guide block 211 to drive the release frame 811 to discharge the capsule from the gripping frame 87.

[0114] It is worth mentioning that the second directional gear 86 and the second directional rack 88 in the discharge mechanism 8 make it easier to discharge the capsules, and the capsules can be transferred and unloaded as the carrying mechanism 2 moves.

[0115] In detail, firstly, the bearing mechanism 2 moves the processed capsule to the discharge station. During this process, it passes through the action of the third trapezoidal block 81 and the fifth drive rack 82 in sequence. First, the third trapezoidal block 81 connected to the frame contacts and squeezes the first trapezoidal block 265 in the negative pressure component 26, causing the first trapezoidal block 265 to move downward and thus release the restriction on the connecting plate 264. Then, under the elastic force of the second telescopic member 263, the piston plate 262 is reset, thus releasing the fixation on the upper cap 200. At this time, the upper cap 200 is only connected to the inner wall of the fixing hole 252. Under the drive of the first drive cylinder 222, the upper cap 200 separates from the second holding component 22, and the top plate 223 is reset. Next, the fifth drive rack 82 drives the first gear 243 to mesh and transmit power, thus releasing the fixation of the locking component 24 on the capsule body 100. When the material is discharged from the discharge mechanism 8, the second directional rack 88 on one side of the base plate 212 first meshes with the second directional gear 86 on the gripping frame 87, thereby rotating the gripping frame 87 180° to be directly above the capsule. Then, the fifth drive cylinder 84 drives the guide rod 85 through the through hole 83 to push the capsule out and lock it into the gripping frame 87. Subsequently, the carrying mechanism 2 continues to move, and the remaining part of the second directional rack 88 continues to mesh with the second directional gear 86, causing the gripping frame 87 to rotate the capsule 180° to be above the collection box 812. Immediately afterwards, the carrying mechanism 2 drives the guide block 211 to squeeze the fourth trapezoidal block 810, causing it to fall to a certain height. At the same time, it drives the release frame 811 to discharge the capsule from the gripping frame 87 and into the collection box 812. After the carrying mechanism 2 moves away, the release frame 811 resets under the action of the second spring 89.

[0116] It should be noted that the friction between the inner wall of the fixing hole 252 on the second gear 251 and the upper cap 200 is less than the rigid force between the outer protruding edge 400 and the locking groove 500.

[0117] Example 3

[0118] Furthermore, such as Figure 27 As shown, a method adapted to a blueberry lutein soft capsule preparation system includes the following steps:

[0119] Step 1, the process of loading the capsule 100 and the cap 200: First, at the first loading station, the capsule 100, which has been sorted on the arrangement component 31, is taken out by the tensioning component 33 and the transfer component 32 and placed into the first holding component 21 on the carrying mechanism 2. During the process, the auxiliary component 23 converges the multiple outward protruding edges 400 arranged in a ring on the capsule 100. Then, driven by the transmission mechanism 1, the carrying mechanism 2 moves to the second loading station. In the second loading mechanism 4, the cap 200 is placed into the second holding component 22 under the joint action of the screening component 41 and the loading component 42. During the process, the negative pressure component 26 sucks the cap 200 to prevent it from falling off.

[0120] Step two, inspection process: Next, at the correction station, the upper cap 200 is rotated by the locking assembly 25 so that the outer protruding edge 400 of the bladder body 100 is engaged with the slot 500 on the inner wall of the upper cap 200. Then, the position of the bladder body 100 is fixed by the locking assembly 24 and the engagement between the bladder body 100 and the upper cap 200 is released, so as to ensure that the engagement between the upper cap 200 and the bladder body 100 is tight after the subsequent work is completed.

[0121] Step 3, filling and closing process: As the carrying mechanism 2 moves to the punching and injection station, the processing mechanism 6 opens the vent holes 300 on the capsule 100 and the upper cap 200 and injects the powder into the capsule 100. Then, at the closing station, the exhaust mechanism 7 helps the capsule to expel the air accumulated inside the capsule when the upper cap 200 and the capsule 100 are closed. Then the capsule 100 and the upper cap 200 are assembled.

[0122] Step four, the unloading process: After processing, the capsules are unsecured at the unloading station by the locking assembly 24 and the negative pressure assembly 26, thereby discharging the capsules.

10. A method adapted to the blueberry lutein soft capsule preparation system according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1, Cap and Cap Assembly Process: First, at the first loading station, the capsules that have been arranged on the arrangement assembly are taken out by the tensioning and transfer components and placed into the first holding assembly on the carrying mechanism. During the process, the auxiliary components converge the multiple outward protruding edges of the capsules arranged in a ring. Then, driven by the transmission mechanism, the carrying mechanism moves to the second loading station. In the second loading mechanism, the upper cap is placed into the second holding assembly under the combined action of the screening and loading components. During the process, the upper cap is sucked tight by the negative pressure component to prevent it from falling off. Step two, inspection process: Next, at the correction station, the upper cap is rotated by the locking assembly so that the outer protruding edge of the bladder body is engaged with the groove on the inner wall of the upper cap. Then, the position of the bladder body is fixed by the locking assembly and the engagement of the bladder body and the upper cap is released, so as to ensure that the engagement between the upper cap and the bladder body is tight after the subsequent work is completed. Step 3, filling and closing process: As the carrying mechanism moves to the punching and injection station, the processing mechanism opens vent holes on the capsule and the upper cap and injects powder into the capsule. Then, at the closing station, the exhaust mechanism helps the capsule to expel the air accumulated inside the capsule when the upper cap and capsule are closed. Finally, the capsule and the upper cap are assembled. Step four, the unloading process: After processing, the capsules are unsecured by the locking components and the negative pressure components at the unloading station, and then the capsules are discharged.
