Description

Technical Field

[0001] This invention relates to the field of pharmaceutical manufacturing technology, and more specifically, to a soft capsule forming apparatus and manufacturing process. Background Technology

[0002] The compression molding apparatus is a key piece of equipment for the industrial mass production of soft capsules. Its workflow is highly integrated, precise, and efficient. First, a constant-temperature system stably supplies the adhesive solution, compressing it into two continuous, uniform films. Next, a quantitative filling system precisely injects the contents between the two films. Then, a pair of double rollers, their surfaces engraved with capsule grooves and sealing teeth, rotate synchronously in opposite directions, causing the two films to fit tightly together to encapsulate the contents. Simultaneously, the sealing teeth press the film edges together to ensure a seal. Afterward, a cutting structure divides the continuous films into individual soft capsules. Finally, a cooling and shaping unit achieves stable molding, enabling efficient and precise large-scale production throughout the entire process. This apparatus is widely used in pharmaceuticals, health products, and other fields, and can adapt to various capsule shapes, including round and oval, flexibly meeting the production needs of products with different specifications. Existing soft capsule forming equipment produces soft capsules at relatively high temperatures. Since the capsule shells are primarily composed of gelatin and glycerin, containing a significant amount of moisture, the formed soft capsules are soft and sticky. If not dried promptly, they are prone to sticking, deformation, and even seal failure. Therefore, soft capsules produced by existing forming equipment typically need to be conveyed into drying equipment for drying. However, the soft capsules produced by the forming equipment tend to accumulate on the conveyor belt during transport. Due to the high surface stickiness of freshly formed soft capsules and their time spent on the conveyor belt, the surfaces of the accumulated capsules easily stick together, forming "capsule clumps." Once clumping occurs, not only is uniform separation difficult during subsequent entry into the drying equipment, but the sealing edges of the capsules may also be damaged during separation, causing leakage of the contents. Therefore, we propose a soft capsule forming device and production process. Summary of the Invention

[0013] A soft capsule manufacturing process, applicable to the above-mentioned molding apparatus, includes the following steps: S1. Soft capsule forming operation: The soft capsule raw material is pressed and formed by the main body of the forming machine to obtain soft capsule products. After forming, the soft capsules are guided into the dispersion drum by the feeding guide plate. S2. The initial dispersion of soft capsules is carried out by a motor as the power source to drive the dispersion drum to rotate. The soft capsules that enter the dispersion drum are diverted by impacting the spherical protrusions at the bottom of the inner cavity of the dispersion drum. Finally, they are discharged from multiple discharge troughs arranged in a ring array and enter multiple cooling chambers of the cold vibrating drum in a dispersed state. S3. Deep dispersion of soft capsules: During S2, the external air supply equipment is activated, and dry cold air is delivered to multiple flexible tubes through the cold air pipe, and then input into the support tube through the flexible tube. Since the inner cavity of the support tube enters the cooling chamber, the soft capsules in the chamber are cooled to ensure the stability of the capsule material morphology. During the rotation of the dispersion drum, it can drive the cooling drum to continuously bounce up and down. The vibration generated by this bouncing motion can vibrate and disperse multiple soft capsules in each cooling chamber to prevent the soft capsules from sticking together. S4. The soft capsules are transferred sequentially. The rotating drum rotates, and the regulating drum rotates synchronously through the transmission column. The curved column on the regulating drum pushes the rocker plate in sequence to open the cover plate at the bottom of each cooling chamber. The soft capsules fall into the guide bin. After the curved column leaves, the cover plate automatically resets under the action of the torsion spring. This process realizes that the soft capsules fall one by one and avoids accumulation. S5. Uniformly dispersed conveying operation: The soft capsules enter the reciprocating diversion component through the guide bin and regulating pipe. The regulating cylinder rotates to make the regulating pipe make a circular motion, which drives the receiving frame to slide back and forth along the slide bar. The soft capsules are evenly distributed to each discharge channel of the diversion frame and finally fall evenly onto the conveyor. S6. Subsequent operations: The conveyor feeds the soft capsules into the transfer machine, where a blower blows them to an external drying device. After drying, the products that pass the screening and inspection enter the packaging process and are finally stored in the warehouse.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the design of a capsule dispersion mechanism, enables multiple dispersions of the high-temperature, high-viscosity soft capsules produced by the molding machine. This allows the soft capsules to be evenly dispersed and transported on a conveyor. First, a dispersion drum initially disperses the falling soft capsules and guides them into multiple cooling chambers of a cooling vibrating drum. Next, the cooling vibrating drum vibrates and disperses the multiple soft capsules in each cooling chamber, preventing them from sticking together and cooling them down, resulting in a more stable shape for the capsule shells. Finally, an adjusting drum controls the sequential feeding of materials from each cooling chamber, and a reciprocating diversion component evenly distributes the soft capsules on the conveyor. This achieves the effect of evenly dispersing and transporting the freshly formed soft capsules, preventing them from agglomerating and piling up during transport. This solves the problem that soft capsules tend to stick together and form difficult-to-separate clumps during transport due to agglomeration and piling up.

[0015] 2. This invention arranges spherical protrusions at the bottom of the inner cavity of the dispersing drum. After the soft capsules pressed by the main body of the molding machine are guided into the dispersing drum by the feeding guide plate, the soft capsules fall on the spherical protrusions. The spherical protrusions can disperse the soft capsules in all directions, making it difficult for the soft capsules to form an aggregated state. In addition, in conjunction with the low-speed rotation of the dispersing drum, the spherical protrusions rotate synchronously at a low speed, so that the position of the soft capsules falling on the spherical protrusions changes continuously. This avoids the problem of soft capsules concentrating in the same position on the spherical protrusions and being easily dispersed in the same area by the spherical protrusions, which would cause the soft capsules to stick together. At the same time, the low-speed rotation of the dispersing drum controlled by the motor avoids the excessive centrifugal force caused by excessive rotation speed, which would cause the soft capsules to agglomerate and stick together. The gentle centrifugal force is not enough to drive the soft capsules to move excessively. Instead, it can work with the spherical protrusions to reduce the adhesion force on the contact surface, allowing the soft capsules to slide smoothly along the surface of the spherical protrusions into the discharge trough of the annular array.

[0016] 3. This invention involves arranging multiple wedge-shaped blocks at the top of the inner cavity of the cooling drum. The top of each wedge-shaped block is designed with an inclined surface structure. During the rotation of the dispersing drum, multiple rotating rollers at its bottom roll on the inclined surface structure at the top of the wedge-shaped blocks at the top of the inner cavity of the cooling drum. The dispersing drum does not shift in the vertical direction. As the rotating rollers roll from the lower end to the upper end of the inclined surface structure at the top of the wedge-shaped blocks, they can press down on the wedge-shaped blocks, causing the cooling drum to move downwards in the vertical direction and compressing the elastic spring on the support tube. This continues until the rotating rollers fall from the highest point of the wedge-shaped blocks, losing downward pressure on the wedge-shaped blocks. This releases the elasticity of the elastic spring, causing the cooling drum to rapidly rise in the vertical direction, forming a continuous up-and-down tumbling motion of the cooling drum. The vibration generated by the winnowing motion disperses the multiple soft capsules in each cooling chamber, preventing them from sticking together. Combined with the cooling effect of the cold air, this helps the capsule shells form a more stable shape. The dry, cold air lowers the temperature and hardens the shells, physically reducing the possibility of adhesion. The continuous vibration acts like a miniature "screening machine," constantly separating any soft capsules that may come into contact, disrupting the conditions for adhesion. The combination of these two factors solves the adhesion problem from both internal and external perspectives. Furthermore, by using the rotation of the dispersing drum to drive the vibration of the cooling drum, no additional drive device is needed, making the entire mechanism compact, reducing costs and failure rates, and improving energy utilization efficiency.

[0017] 4. This invention utilizes multiple cover plates movably arranged at the bottom of the cooling vibrating cylinder. The rotation of the dispersing rotating cylinder drives the rotation of the adjusting cylinder. The curved column on the outer circumference of the adjusting cylinder rotates with it. The head of the curved column presses against the inclined protrusion structure on the side wall of the rocker plate on the side of the cooling vibrating cylinder's inclined groove, pushing the rocker plate to rotate into the inclined groove. This, in turn, causes the cover plate to open the bottom outlet of the cooling chamber, allowing the soft capsule inside the cooling chamber to fall into the guide hopper. One end of the torsion spring contacts the second fixed rod, and the other end presses against the rocker plate. After the curved column disengages from the rocker plate, the torsion spring can drive the cover plate to reset and close. As the regulating cylinder continues to rotate, the soft capsules in multiple cooling chambers are sequentially conveyed into the guide hopper, and then conveyed downwards through the guide hopper. This prevents the soft capsules in multiple cooling chambers from piling up and falling, ensuring that the soft capsules fall in batches, in small quantities, and in an orderly manner, rather than being poured out in large quantities at once. This fundamentally avoids the problems of secondary accumulation and adhesion. Furthermore, this mechanism provides a relatively fixed residence time for the soft capsules in each cooling chamber, ensuring that they can be cooled sufficiently and evenly, thereby guaranteeing the morphological stability of the soft capsules.

[0018] 5. This invention also designs the top of the inner cavity of the receiving frame as a long groove-shaped structure and arranges the regulating tube within the long groove-shaped structure. When the dispersing drum rotates and drives the regulating drum to rotate synchronously, the regulating drum can also drive the regulating tube to make a circular motion. Since the regulating tube is arranged within the long groove-shaped structure at the top of the inner cavity of the receiving frame, when the regulating tube makes a circular motion, it will cause the receiving frame to slide back and forth along the slide bar. The soft capsules falling into the guide bin of the regulating drum will continue to fall downward through the regulating tube and enter the receiving frame. Through the back and forth sliding of the receiving frame, the soft capsules can be more evenly dispersed into the multiple discharge channels of the diversion frame. Finally, the soft capsules are evenly laid out on the conveyor belt, avoiding the accumulation of soft capsules falling at a certain point on the conveyor belt. Attached Figure Description

[0021] Example 1, as Figures 1 to 15 As shown, this embodiment provides a soft capsule forming apparatus, including a forming machine body 1. The forming machine body 1 is a prior art device and will not be described in detail. A capsule dispersion mechanism 2 is arranged at the output end of the forming machine body 1, and a conveyor 3 is arranged below the capsule dispersion mechanism 2. The conveyor 3 is a conventional belt conveyor. The capsule dispersion mechanism 2 is used to convey multiple soft capsules formed by the forming machine body 1 in a dispersed state onto the conveyor belt of the conveyor 3. The capsule dispersion mechanism 2 includes a fixed frame 21, a dispersion drum 22 is rotatably arranged inside the fixed frame 21, and a cooling vibration drum 23 is movably arranged at the bottom of the fixed frame 21. The active arrangement is located inside the cooling cylinder 23, which has multiple cooling chambers 2301. An adjusting cylinder 24 is rotatably arranged at the bottom of the cooling cylinder 23, and a reciprocating diverting assembly 25 is arranged below the adjusting cylinder 24. The reciprocating diverting assembly 25 is arranged at the top of the conveyor 3. The dispersing rotating cylinder 22 is used to receive the soft capsules output from the molding machine body 1 and to transport multiple soft capsules into the multiple cooling chambers 2301 of the cooling cylinder 23 in a dispersed state. The adjusting cylinder 24 is used to transfer the soft capsules in the cooling chambers 2301 to the reciprocating diverting assembly 25, and the reciprocating diverting assembly 25 disperses and transports the soft capsules to the conveyor 3.

[0022] This invention, through the design of a capsule dispersion mechanism 2, can disperse the high-temperature, high-viscosity soft capsules produced by the molding machine body 1 multiple times, enabling the soft capsules to be evenly dispersed on the conveyor 3 for transport. First, the dispersion drum 22 initially disperses the concentrated soft capsules and guides them into multiple cooling chambers 2301 of the cooling drum 23. Next, the cooling drum 23 can vibrate and disperse multiple soft capsules in each cooling chamber 2301, preventing the soft capsules from sticking together and cooling the soft capsules, so that the soft capsule shells form a more stable shape. Finally, the regulating drum 24 controls the material to fall into each cooling chamber 2301 one by one, and the reciprocating diversion component 25 evenly distributes the soft capsules on the conveyor 3, achieving the effect of evenly dispersing and transporting the freshly formed soft capsules, avoiding the formation of aggregated and piled-up transport states, and solving the problem that soft capsules are prone to sticking together and forming difficult-to-separate clumps during transport due to aggregation and pile-up.

[0023] In an embodiment of the present invention, the molding machine body 1 includes a plurality of feeding guide plates 101, which are arranged above the feed inlet of the dispersing drum 22. The feeding guide plates 101 are used to guide the soft capsules pressed by the molding machine body 1 into the dispersing drum 22. A transfer machine 4 is arranged at the output end of the conveyor 3. The transfer machine 4 is used to transfer the soft capsules output by the conveyor 3 to an external drying device for drying. The transfer machine 4 includes a feeding hopper 401 and a discharge pipe 402. The feeding hopper 401 is arranged below the output end of the conveyor 3. The output end of the discharge pipe 402 is connected to the external drying device. A blower is arranged inside the transfer machine 4. The soft capsules received by the feeding hopper 401 can be blown into the discharge pipe 402 by the blower and conveyed forward. The transfer machine 4 is a conventional airflow conveying mechanism in the example. The airflow generated by the blower blows the soft capsules from the feeding hopper 401 to the discharge pipe 402 and finally into the external drying device.

[0024] In an embodiment of the present invention, an annular groove 2201 is provided on the outer circumference of the dispersing drum 22, and a sliding protrusion structure is arranged on the inner sidewall of the fixing frame 21. The dispersing drum 22 rotates through the annular groove 2201 and the sliding protrusion structure, ensuring that the dispersing drum 22 is unlikely to undergo vertical displacement during rotation. A motor 2101 is installed at the bottom of the fixing frame 21, and a gear 2102 is connected to the output end of the motor 2101. Gear 2102 meshes with a gear 2103, and gears 2102 and 2103 are rotatably arranged on the top of the fixing frame 21. A toothed edge 2202 is arranged on the outer circumference of the dispersing drum 22, and gear 2103 meshes with the toothed edge 2202. When the motor 2101 operates, it can drive gears 2102 and 2103 to rotate, and gear 2103 can drive the dispersing drum 22 to rotate through the toothed edge 2202.

[0025] In an embodiment of the present invention, a conical hopper 2203 is integrally formed on the top of the dispersing drum 22. The conical hopper 2203 can guide the soft capsules to slide quickly and smoothly into the interior of the dispersing drum 22, avoiding accumulation and blockage at the feed inlet and improving the feeding efficiency. A spherical protrusion 2204 and a plurality of discharge grooves 2205 are arranged at the bottom of the inner cavity of the dispersing drum 22. The spherical protrusion 2204 is a spherical protrusion structure, and the plurality of discharge grooves 2205 are arranged in a ring array on the side wall of the spherical protrusion 2204. This invention utilizes spherical protrusions 2204 arranged at the bottom of the inner cavity of the dispersing drum 22. After the soft capsules pressed by the forming machine body 1 are guided into the dispersing drum 22 by the feeding guide plate 101, the soft capsules fall onto the spherical protrusions 2204. The spherical protrusions disperse the soft capsules in all directions, making it difficult for them to aggregate. Furthermore, in conjunction with the low-speed rotation of the dispersing drum 22, the spherical protrusions 2204 rotate synchronously at a low speed, causing the position of the soft capsules continuously changing as they fall onto the spherical protrusions 2204. This prevents the soft capsules from concentrating in the same position on the spherical protrusions 2204 and from being easily dispersed by the spherical protrusions 2204. The problem of soft capsules sticking together due to being scattered in the same area is addressed. At the same time, the low-speed rotation of the dispersing drum 22 is controlled by the motor 2101 to avoid excessive centrifugal force caused by excessive rotation speed, which would cause the soft capsules to clump together. The gentle centrifugal force is not enough to drive the soft capsules to move excessively. Instead, it can work with the spherical protrusions 2204 to reduce the adhesion force on the contact surface, allowing the soft capsules to slide smoothly along the surface of the spherical protrusions 2204 into the annular array of discharge channels 2205. The multiple discharge channels 2205 arranged in an annular array along the side wall of the spherical protrusions 2204 act like multiple precise outlets, evenly distributing the dispersed soft capsules into the multiple cooling chambers 2301 below.

[0026] In an embodiment of the present invention, a plurality of support tubes 2302 are arranged on the outer circumference of the cooling cylinder 23, and the inner cavity of the support tubes 2302 is in communication with the inner cavity of the cooling cylinder 23; the support tubes 2302 movably pass through the top of the fixing frame 21, and the outer circumference of the support tubes 2302 is connected to a limiting block 2303 and a fixing block 2304. The limiting block 2303 is arranged below the fixing frame 21, and the fixing block 2304 is arranged above the fixing frame 21. A spring spring 2305 is arranged between the fixing frame 21 and the fixing block 2304, and the spring spring 2305 is movably sleeved on the outer circumference of the support tubes 2302; a support frame 2104 is connected to the top of the fixing frame 21, and a cooling pipe 2105 is installed on the top of the support frame 2104. A plurality of flexible pipes 2106 are connected to the output end of the cooling pipe 2105, and the output end of the flexible pipes 2106 is connected to the input end of the support tube 2302. The input end of the cooling pipe 2105 is connected to an external air supply device through a pipe. By activating the external air supply equipment, dry cold air is delivered through the cold air pipe 2105 to multiple flexible pipes 2106, and then from the flexible pipes 2106 into the support pipe 2302. Since the inner cavity of the support pipe 2302 is connected to the inner cavity of the cooling cylinder 23, the cold air smoothly enters the cooling chamber 2301. Through the continuous delivery of dry cold air, the dry cold air can diffuse into the cooling chamber 2301 and the inner cavity of the dispersing rotating cylinder 22, and escape, forming a dynamic low-temperature flow channel state, which can quickly remove heat. In this state, on the one hand, the continuously replenished cold air can continuously cover the soft rubber in the cooling chamber 2301. Even though the cold air escapes quickly from the capsule surface, the newly introduced cold air can still maintain the overall low temperature environment inside the chamber, ensuring that the temperature of the soft capsule material drops rapidly, promoting the initial solidification of the gelatin component and reducing surface stickiness. On the other hand, the dynamically flowing cold air can also remove the small amount of moisture remaining on the surface of the soft capsule due to molding, helping to improve the hardness of the capsule material. At the same time, in conjunction with the up-and-down shaking vibration of the cold vibration cylinder 23, each soft capsule can fully contact the cold air in the airflow, quickly hardening the shell of the soft capsule, significantly reducing its surface stickiness, and fundamentally avoiding the problem of capsules sticking together to form "capsule clusters".

[0027] In an embodiment of the present invention, a plurality of rotating rollers 2206 are rotatably arranged at the bottom of the dispersing drum 22, and the plurality of rotating rollers 2206 are arranged in a ring array; a plurality of wedge blocks 2306 are arranged at the top of the inner cavity of the cooling drum 23, and the top of the wedge blocks 2306 has an inclined surface structure; the rotating rollers 2206 at the bottom of the dispersing drum 22 are rolled on the top of the wedge blocks 2306; when the dispersing drum 22 rotates, it can drive the cooling drum 23 to form an up-and-down bumping motion, so that while the cooling drum 23 cools the soft capsules in the multiple cooling chambers 2301, it forms a vibration dispersion effect on the multiple soft capsules in each cooling chamber 2301 through the vibration generated by its own bumping.

[0028] This invention utilizes multiple wedge-shaped blocks 2306 arranged at the top of the inner cavity of the cooling cylinder 23. The tops of the wedge-shaped blocks 2306 are designed with an inclined surface structure. During the rotation of the dispersing drum 22, multiple rotating rollers 2206 at its bottom roll on the inclined surface structure at the top of the wedge-shaped blocks 2306 at the top of the inner cavity of the cooling cylinder 23. The dispersing drum 22 does not shift vertically. As the rotating rollers 2206 roll from the lower end to the upper end of the inclined surface structure at the top of the wedge-shaped blocks 2306, they press downwards on the wedge-shaped blocks 2306, causing the cooling cylinder 23 to move downwards vertically and compressing the elastic spring 2305 on the support tube 2302. This continues until the rotating rollers 2206 fall from the highest point of the wedge-shaped blocks 2306, losing downward pressure on the wedge-shaped blocks 2306. This releases the elasticity of the elastic spring 2305, allowing the cooling cylinder 23 to... The vertical direction rises rapidly, creating a continuous up-and-down tumbling motion of the cooling cylinder 23. The vibration generated by this tumbling motion disperses the multiple soft capsules in each cooling chamber 2301, preventing them from sticking together. Combined with the cooling effect of the cold air on the soft capsules, this makes the capsule shells form a more stable shape. The dry cold air is responsible for lowering the temperature and hardening the capsule shells, reducing the possibility of adhesion from a physical perspective. The continuous vibration acts like a miniature "screening machine," constantly separating the soft capsules that may come into contact, disrupting the conditions for adhesion. The combination of these two factors solves the adhesion problem from both "internal" and "external" perspectives. Furthermore, by using the rotation of the dispersing cylinder 22 to drive the vibration of the cooling cylinder 23, no additional drive device is needed, making the entire mechanism compact, reducing costs and failure rates, while improving energy utilization efficiency.

[0029] In an embodiment of the present invention, the adjusting cylinder 24 includes a fixed column 2401, the outer circumferential wall of the fixed column 2401 having a rotating groove 2402, and the inner circumferential wall of the cooling cylinder 23 having an annular protrusion structure. The fixed column 2401 is rotatably arranged on the annular protrusion structure through the rotating groove 2402. The bottom of the dispersing rotating cylinder 22 is connected to a transmission column 2207, and the outer circumferential wall of the transmission column 2207 is connected to a plurality of sliding protrusions 2208. The fixed column 2401 has a circular groove 2403 from top to bottom, and the inner sidewall of the circular groove 2403 has a... A sliding groove 2404 is provided, a transmission column 2207 is movably arranged in a circular groove 2403, and a sliding protrusion 2208 is movably arranged in a sliding groove 2404. When the transmission column 2207 rotates, it can drive the adjusting cylinder 24 to rotate through the sliding protrusion 2208. When the cooling cylinder 23 performs up-and-down swaying motion, it can synchronously drive the adjusting cylinder 24 to move up and down on the transmission column 2207 through the fixed column 2401, thereby ensuring the synchronicity of the vertical displacement of the adjusting cylinder 24 and the cooling cylinder 23.

[0030] In an embodiment of the present invention, the outer circumferential wall of the cooling cylinder 23 is provided with a plurality of inclined grooves 2307, and the inner sidewall of the inclined grooves 2307 is connected to a first fixing rod 2308 and a second fixing rod 2309; a plurality of cover plates 2311 are movably arranged at the bottom of the cooling cylinder 23, and the cover plates 2311 are arranged at the bottom outlet of the cooling chamber 2301, and the cover plates 2311 are used to form a closed state or an open state for the bottom outlet of the cooling chamber 2301; a rocker plate 23 is integrally formed on one side of the cover plate 2311. 12. The rocker plate 2312 is arranged at an angle on the side of the inclined groove 2307, and the side wall of the rocker plate 2312 is set as an inclined protrusion structure; a torsion spring 2310 is sleeved on the outer circumference of the first fixing rod 2308, one end of the torsion spring 2310 is arranged on the second fixing rod 2309, and the other end is pressed against the side wall of the rocker plate 2312; a curved column 2405 is connected to the outer circumference of the adjusting cylinder 24, and the head of the curved column 2405 is pressed against the inclined protrusion structure of the side wall of the rocker plate 2312.

[0031] This invention utilizes multiple cover plates 2311 movably arranged at the bottom of the cooling cylinder 23. The rotation of the dispersing rotating cylinder 22 drives the rotation of the adjusting cylinder 24. The curved column 2405 on the outer circumference of the adjusting cylinder 24 rotates with the adjusting cylinder 24. The head of the curved column 2405 presses against the inclined protrusion structure on the side wall of the rocker plate 2312 on the side of the inclined groove 2307 of the cooling cylinder 23, pushing the rocker plate 2312 to rotate into the inclined groove 2307. This, in turn, causes the cover plates 2311 to open the bottom outlet of the cooling chamber 2301, allowing the soft capsules inside the cooling chamber 2301 to fall into the guide bin 2406. One end of the torsion spring 2310 contacts the fixed rod 2309, and the other end presses against the rocker plate 2312. The curved column 2405 and the rocker plate 2312... After contact is broken, the torsion spring 2310 can drive the cover plate 2311 to reset and close. As the regulating cylinder 24 continues to rotate, it can sequentially transport the soft capsules in multiple cooling chambers 2301 into the guide bin 2406, and continue to transport them downward through the guide bin 2406. This ensures that the soft capsules in multiple cooling chambers 2301 do not pile up and fall down, ensuring that the soft capsules fall in batches, in small quantities, and in an orderly manner, rather than being poured out in large quantities at once. This fundamentally avoids the problem of secondary accumulation and adhesion. Furthermore, this mechanism provides a relatively fixed residence time for the soft capsules in each cooling chamber 2301, ensuring that they can be cooled sufficiently and evenly, thereby ensuring the morphological stability of the soft capsules.

[0032] It is particularly important to note that the inclined groove 2307 itself is only a partial structure to accommodate the rocker 2312 and the torsion spring 2310, and it is not directly connected to the cooling chamber 2301. Therefore, the design of the inclined groove 2307 will not cause a large amount of cold air to escape from the cooling chamber 2301. Furthermore, in the entire feeding mechanism, only one cover plate 2311 is open at any given time. Since the curved column 2405 on the outer circumference of the adjusting cylinder 24 rotates synchronously with the adjusting cylinder, its pressing contact with the rocker 2312 has a sequential triggering characteristic. When the curved column 2312... When 405 rotates to the rocker arm 2312 corresponding to a certain cooling chamber 2301, only that rocker arm 2312 is pushed to open the corresponding cover plate 2311. At this time, the covers of all other cooling chambers remain closed under the action of the torsion spring 2310. On the one hand, the opening time of a single cover plate 2311 is short, and the amount of cold air escaping through the temporary opening is minimal. On the other hand, the bottom of the cooling chamber with the cover plate 2311 not open is completely sealed. With the cold air continuously input by the support pipe 2302, the low temperature environment inside the chamber can be effectively maintained.

[0033] In another embodiment of the present invention, a guide bin 2406 is arranged in the inner cavity of the regulating cylinder 24, and the guide bin 2406 is arranged below the cover plate 2311; an regulating pipe 2407 is connected to the bottom of the regulating cylinder 24, and the inner cavity of the regulating pipe 2407 is connected to the inner cavity of the guide bin 2406; the reciprocating diversion assembly 25 includes a diversion frame 2501 arranged on the top of the conveyor 3, the inner cavity of the diversion frame 2501 is divided into multiple discharge channels by multiple diversion plates 2502, multiple sliding rods 2503 are connected to the inner side wall of the diversion frame 2501, a receiving frame 2504 is slidably arranged on the sliding rod 2503, the inner cavity of the receiving frame 2504 is connected to the inner cavity of the diversion frame 2501, the top of the inner cavity of the receiving frame 2504 is a long groove structure, and the regulating pipe 2407 is movably arranged in the long groove structure.

[0034] The present invention further designs the top of the inner cavity of the receiving frame 2504 as a long groove structure and movably arranges the regulating tube 2407 within the long groove structure. When the dispersing drum 22 rotates and drives the regulating drum 24 to rotate synchronously, the regulating drum 24 can also drive the regulating tube 2407 to perform a circular motion. Since the regulating tube 2407 is movably arranged within the long groove structure at the top of the inner cavity of the receiving frame 2504, when the regulating tube 2407 performs a circular motion, it will cause the receiving frame 2504 to slide back and forth along the slide bar 2503. The soft capsules falling into the guide bin 2406 of the regulating drum 24 will continue to fall downward through the regulating tube 2407 and enter the receiving frame 2504. Through the back and forth sliding of the receiving frame 2504, the soft capsules can be more evenly dispersed into the multiple discharge channels of the diversion frame 2501, ultimately achieving a uniform and flat state of the soft capsules on the conveyor belt, avoiding concentrated falling at a certain point on the conveyor belt and forming accumulation. The reciprocating motion is directly driven by the rotation of the regulating cylinder 24, without the need for an additional power source. This not only simplifies the structure and reduces costs, but also cleverly connects all the links of the entire dispersing mechanism (dispersing, cooling, vibration, and material distribution) into a synchronous system driven by a single motor, improving the overall operational stability and energy utilization efficiency.

[0035] This invention employs a multi-component collaborative structure. The dispersing drum 22, using spherical protrusions 2204 and a discharge trough 2205, achieves initial dispersion and feeding of soft capsules. The cooling drum 23, combined with the cooling chamber 2301 and vibration, cools the soft capsules and prevents them from sticking together. The regulating drum 24, through the linkage of the curved column 2405 and the cover plate 2311, controls the orderly dropping of soft capsules. The reciprocating diversion component 25, relying on the slide rod 2503 and the receiving frame 2504, achieves uniform and even conveying of the soft capsules. Ultimately, this invention achieves the dispersed conveying effect of freshly formed soft capsules. It solves the core problems of existing technologies where lubricant easily contaminates the medicine when used to prevent sticking, and where cold air is difficult to penetrate and accumulates capsule clusters when using only cold air for cooling, leading to secondary sticking during conveying. Furthermore, the entire mechanism is driven by a single motor, with each structure functioning through mechanical linkage, without the need for additional power units or complex control modules.

[0036] Example 2: This example provides a soft capsule manufacturing process applicable to the above-mentioned molding apparatus, including the following steps: S1. Soft capsule forming operation: Start the forming machine body 1, and transport the pre-prepared capsule material liquid and filling liquid to the corresponding feeding structure of the forming machine body 1 respectively. The forming machine body 1 encapsulates the filling liquid with the capsule material liquid through the molding process and presses it into multiple soft capsule products. The formed soft capsules are guided by multiple feeding guide plates 101 on the forming machine body 1 and accurately transported to the conical hopper 2203 at the top of the dispersing drum 22. S2. Initial dispersion of soft capsules: The motor 2101 at the bottom of the fixed frame 21 is started to rotate at low speed. The output end of the motor 2101 drives the gear 1 2102 to rotate. The gear 1 2102 drives the gear 2103 to rotate through meshing transmission. The gear 2103 then meshes with the toothed edge 2202 on the outer circumference of the dispersion drum 22, driving the dispersion drum 22 to rotate at low speed around its own axis. The dispersion drum 22 cooperates with the sliding protrusion structure on the inner side wall of the fixed frame 21 through the annular groove 2201 to ensure rotational stability. The soft capsules entering the dispersion drum 22 are diverted by impacting the spherical protrusion 2204. With the dispersion drum 22 driving the spherical protrusion 2204 to rotate at low speed, the soft capsules can be prevented from falling in the same position. Finally, they are discharged from multiple discharge troughs 2205 arranged in a ring array and enter the multiple cooling chambers 2301 of the cold vibrating drum 23 in a dispersed state. S3. Deep dispersion of soft capsules: During S2, the external air supply equipment is activated, and dry cold air is delivered to multiple flexible tubes 2106 through the cold air pipe 2105. The air then enters the support tube 2302 through the flexible tubes 2106. Since the inner cavity of the support tube 2302 is connected to the inner cavity of the cooling cylinder 23, the cold air smoothly enters the cooling chamber 2301 to cool the soft capsules inside, reducing their temperature and ensuring the stability of the capsule material's morphology. During the rotation of the dispersion drum 22, multiple rotating rollers 2206 at its bottom roll on the inclined surface structure at the top of the wedge-shaped block 2306 at the top of the inner cavity of the cooling cylinder 23. The dispersion drum 22 does not shift vertically, allowing the rotating rollers 2206 to roll off the wedge-shaped block 2306. The rolling process from the lower end to the upper end of the inclined surface structure of the part can squeeze the wedge block 2306 downward, so that the cooling cylinder 23 is in a downward position in the vertical direction and compresses the elastic spring 2305 on the support tube 2302 until the rotating roller 2206 falls from the highest point of the top of the wedge block 2306, loses the downward pressure on the wedge block 2306, and the elastic spring 2305 is released. The cooling cylinder 23 quickly rises in the vertical direction, forming a continuous up-and-down swaying motion of the cooling cylinder 23. The vibration generated by this swaying motion can vibrate and disperse the multiple soft capsules in each cooling chamber 2301, preventing the soft capsules from sticking together. Combined with the cooling effect of the cold air on the soft capsules, the shell of the soft capsule forms a relatively stable shape. S4. During the sequential transfer of soft capsules, as the dispersing drum 22 rotates, the transmission column 2207 at its bottom rotates synchronously. The transmission column 2207 engages with the sliding groove 2404 on the inner side wall of the circular groove 2403 of the fixed column 2401 in the adjusting drum 24 via the sliding protrusion 2208 on its outer circumference, driving the adjusting drum 24 to rotate around the axis of the fixed column 2401. The adjusting drum 24 engages with the annular protrusion structure on the inner circumference of the cooling drum 23 via the rotating groove 2402, achieving stable rotation. The curved column 2405 on the outer circumference of the adjusting drum 24 rotates with the adjusting drum 24. The head of the curved column 2405 contacts the inclined protrusion structure on the side wall of the rocker plate 2312 on the side of the inclined groove 2307 of the cooling drum 23, pushing the rocker plate 2312 to rotate inward into the inclined groove 2307. The movement of the regulating cylinder 24 causes the cover plate 2311 to open the bottom outlet of the cooling chamber 2301, allowing the soft capsules inside the cooling chamber 2301 to fall into the guide hopper 2406. One end of the torsion spring 2310 contacts the fixing rod 2309, and the other end is pressed against the rocker arm 2312. After the crank column 2405 disengages from the rocker arm 2312, the torsion spring 2310 can drive the cover plate 2311 to reset and close. As the regulating cylinder 24 rotates, it can sequentially transport the soft capsules from multiple cooling chambers 2301 into the guide hopper 2406, and continue to transport them downwards through the guide hopper 2406, so that the soft capsules in multiple cooling chambers 2301 do not pile up and fall, and provide a certain amount of time for the soft capsules to cool in the cooling chamber 2301. S5. Uniformly dispersed conveying operation: Through the operation of S4, the soft capsules falling into the guide bin 2406 of the regulating cylinder 24 will continue to fall downward through the regulating pipe 2407. During this period, as the regulating cylinder 24 rotates, it can drive the regulating pipe 2407 to make a circular motion. Since the regulating pipe 2407 is movably arranged in the long groove-shaped structure at the top of the inner cavity of the receiving frame 2504, when the regulating pipe 2407 makes a circular motion, it will cause the receiving frame 2504 to slide back and forth along the slide bar 2503, so that the soft capsules in the regulating pipe 2407 can be more evenly dispersed into the multiple discharge channels of the diversion frame 2501, and finally the soft capsules are evenly conveyed to the conveyor belt of the conveyor 3. S6. Subsequent operations: The soft capsules output from conveyor 3 are received by the feed hopper 401 of transfer machine 4. The blower inside transfer machine 4 blows the soft capsules into the discharge pipe 402, and then transports them to external drying equipment for drying treatment. The drying treatment improves the hardness and stability of the capsule material, ensuring that the soft capsules meet the quality standards. After drying, the soft capsules are screened and inspected, and unqualified products are removed. Qualified soft capsules enter the subsequent packaging process, such as bottling and bagging, and finally become finished products for storage.

10. A soft capsule manufacturing process, applicable to the molding apparatus of claim 9, characterized in that, Includes the following steps: S1. Soft capsule forming operation: The soft capsule raw material is pressed and formed by the main body (1) of the forming machine to obtain soft capsule products. After forming, the soft capsules are guided into the dispersing drum (22) by the feeding guide plate (101). S2. The soft capsules are initially dispersed by the motor (2101) rotating at low speed, which drives the dispersion drum (22) to rotate at low speed. The soft capsules entering the dispersion drum (22) are diverted by impacting the spherical protrusions (2204) at the bottom of the inner cavity of the dispersion drum (22). The dispersion drum (22) drives the spherical protrusions (2204) to rotate at low speed, which prevents the soft capsules from falling in the same position. Finally, they are discharged from multiple discharge troughs (2205) arranged in a ring array and enter the multiple cooling chambers (2301) of the cold vibrating drum (23) in a dispersed state. S3, Deep dispersion of soft capsules: During S2, the external air supply equipment is started, and dry cold air is delivered to multiple flexible tubes (2106) through the cold air pipe (2105), and then input into the support tube (2302) through the flexible tube (2106). Since the inner cavity of the support tube (2302) enters the cooling chamber (2301), the soft capsules in the cavity are cooled to ensure the stability of the capsule material. During the rotation of the dispersion drum (22), the cooling vibration drum (23) can be driven to continuously bounce up and down. The vibration generated by this bouncing motion can vibrate and disperse multiple soft capsules in each cooling chamber (2301) to avoid the soft capsules from sticking together. S4. The soft capsules are transferred sequentially. The dispersing drum (22) rotates, and the regulating drum (24) rotates synchronously through the transmission column (2207). The crank column (2405) on the regulating drum (24) pushes the rocker plate (2312) in sequence, opening the cover plate (2311) at the bottom of each cooling chamber (2301). The soft capsules fall into the guide bin (2406). After the crank column (2405) leaves, the cover plate (2311) automatically resets under the action of the torsion spring (2310). This process realizes that the soft capsules fall one by one, avoiding accumulation. S5. Uniformly dispersed conveying operation: The soft capsules enter the reciprocating diversion assembly (25) through the guide bin (2406) and the regulating pipe (2407). The regulating cylinder (24) rotates to make the regulating pipe (2407) make a circular motion, which drives the receiving frame (2504) to slide back and forth along the slide bar (2503).
