Description

Technical Field

[0001] This application belongs to the field of active pharmaceutical ingredient (API) packaging technology, specifically an API packaging device. Background Technology

[0002] Active pharmaceutical ingredients (APIs) are the core raw materials used in the production of various pharmaceutical preparations. They are the effective components that enable drugs to exert their therapeutic effects. APIs themselves are not usually used directly in clinical treatment. They need to undergo a series of processing steps and be mixed with excipients (such as fillers, binders, disintegrants, etc.) to be made into finished drugs in various dosage forms such as tablets, capsules, injections, and ointments before they can be used by patients. The quality of APIs directly determines the effectiveness and safety of the final drug. In the pharmaceutical industry chain, APIs are the key link connecting chemical raw materials and finished drugs. Their research, development, production, and supply have a significant impact on the development of the pharmaceutical industry.

[0003] For example, the utility model patent with announcement number CN222820297U discloses a raw material dispensing device for traditional Chinese medicine plasters, including a material holding shell, a dispensing shell fixedly installed at the lower end of the material holding shell, a rotating disk inside the dispensing shell that is rotated by a motor, a dispensing groove opened on the side of the rotating disk, at least two dispensing grooves are provided and distributed in a circular array along the circumference of the rotating disk, a guide hole is opened at the upper end of the dispensing shell and a discharge hole is opened at the lower end, and an adjustment mechanism is also fixedly installed inside the rotating disk. This raw material dispensing device for traditional Chinese medicine plasters can uniformly and equally dispense and transport the raw materials.

[0004] However, it was discovered during actual use that the device achieves quantitative feeding by rotating the rotating disc to align the dispensing trough with the feeding hole, and then the rotating disc drives the dispensing trough to rotate to align with the feeding hole to complete the dispensing of the raw material.

[0005] However, due to the gap between the rotating disk and the inside of the dispensing shell, the raw materials in the dispensing tank are prone to leaking out through the gap during the rotation of the dispensing tank. At the same time, the raw materials conveyed by the guide hole will continue to accumulate and leak into the gap, which not only wastes the raw materials, but also makes it difficult to clean the leaked raw materials left in the gap and on the inner wall of the dispensing shell. Long-term accumulation may cause cross-contamination and affect the quality of the raw materials dispensed later. Therefore, a raw material dispensing device is provided. Utility Model Content

[0006] The purpose of this application is to provide a drug substance dispensing device in order to solve the problems mentioned above.

[0007] The technical solution adopted in this application is as follows: A raw material dispensing device includes a hopper, a discharge pipe fixedly installed on the bottom surface of the hopper, a metering tube movably sleeved on the outer surface of the discharge pipe, a connecting pipe fixedly installed at the bottom end of the metering tube, a discharge pipe fixedly installed at the bottom end of the connecting pipe, a U-shaped plate provided at the bottom end of the connecting pipe, a weighing sensor fixedly installed through the top surface of the U-shaped plate, a support rod corresponding to the weighing sensor fixedly installed on the outer surface of the metering tube, the bottom end of the support rod contacting the top detection end of the weighing sensor, a housing fixedly installed on the top surface of the hopper, a bearing seat fixedly installed on the top surface of the hopper within the housing, an outer rod fixedly installed through the middle of the bearing seat, an inner rod provided in the middle of the outer rod, a connecting rod fixedly installed at the bottom end of the inner rod, one end of the connecting rod extending into the interior of the discharge pipe, a spiral conveying blade fixedly installed on the outer surface of the end of the connecting rod extending into the discharge pipe, and a drive mechanism connected to the inner rod provided inside the housing.

[0008] In a preferred embodiment, the drive mechanism includes a bearing, a drive gear, a motor, and a pinion. The bearing is fixedly installed on the inner top surface of the housing. The top end of the inner rod is fixedly installed in the middle of the bearing. The drive gear is fixedly installed on the outer surface of the inner rod near the top end. The motor is fixedly installed on the top surface of the housing. The drive end of the motor extends into the interior of the housing. The pinion is fixedly installed on the drive end of the motor, and the pinion meshes with the drive gear.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned scheme, the inner rod of the device drives the spiral conveying blades to rotate in the discharge pipe through the connecting rod, continuously and evenly pushing the raw materials in the hopper into the quantitative tube. The weight of the raw materials in the quantitative tube is transmitted to the weighing sensor through the support rod. The weighing sensor transmits the weight signal to the control system in real time. When the weight is close to the preset value, the control system controls the motor to decelerate and perform slow and precise feeding. When the preset dispensing amount is reached, the motor stops, the spiral conveying blades stop feeding, and then the telescopic cylinder starts, driving the U-shaped plate and the discharge pipe to move downward, so that the discharge pipe is aligned with the receiving container below. This device can realize the independent operation of stirring and conveying without interference. Through the cooperation of the weighing sensor and the motor, the raw materials can be effectively quantitatively dispensed. At the same time, it can avoid problems such as leakage of raw materials during the dispensing process. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] refer to Figures 1-5 As shown, a raw material dispensing device includes a hopper 1, with two feed pipes 23 fixedly installed on the top surface of the hopper 1; a partition is provided inside the hopper 1, which can divide the interior of the hopper 1 into two dispensing cavities, so that the raw materials in the two dispensing cavities can be dispensed simultaneously. Through the two feed pipes 23, the raw materials can be introduced into the corresponding dispensing cavities inside the hopper 1 respectively.

[0023] refer to Figures 1-5 As shown, a discharge pipe 2 is fixedly installed on the bottom surface of the hopper 1. A metering pipe 3 is movably sleeved on the outer surface of the discharge pipe 2. A connecting pipe 4 is fixedly installed at the bottom end of the metering pipe 3. A discharge pipe 5 is fixedly installed at the bottom end of the connecting pipe 4. Two limiting rings 22 are fixedly installed on the outer surface of the discharge pipe 5. A U-shaped plate 6 is provided at the bottom end of the connecting pipe 4. Two vertical rods 20 are fixedly installed on the bottom surface of the hopper 1. Telescopic cylinders 21 are fixedly installed on the sides of the two vertical rods 20 that are far apart from each other. The telescopic end of the telescopic cylinder 21 is connected to the U-shaped plate 6. The side is fixed; an electric control valve is installed on the outer surface of the connecting pipe 4, which can control the opening and closing of the connecting pipe 4. The connecting pipe 4 can be limited by the set limit ring 22. The limit ring 22 is located above and below the bottom surface inside the U-shaped plate 6, so that the connecting pipe 4 can move well during subsequent up and down adjustment. The set telescopic cylinder 21 can drive the U-shaped plate 6 and related components to move flexibly, which facilitates the position of the connecting pipe 4, so that the discharge pipe 5 can discharge the raw materials for packaging.

[0024] refer to Figures 1-5 As shown, a weighing sensor 7 is fixedly installed on the top surface of the U-shaped plate 6, and a support rod 8 corresponding to the weighing sensor 7 is fixedly installed on the outer surface of the quantitative tube 3. The bottom end of the support rod 8 is in contact with the top detection end of the weighing sensor 7. By setting the weighing sensor 7 to contact the support rod 8, the weight of the raw material in the quantitative tube 3 can be detected in real time and accurately, ensuring the consistency of the dispensing amount for each batch. The setting of the support rod 8 can stably transmit the weight of the quantitative tube 3 and the raw material inside, avoiding weight dispersion from affecting the detection accuracy of the weighing sensor 7. In addition, the U-shaped plate 6 provides a stable mounting base for the weighing sensor 7, reducing the interference of external vibration on the weighing.

[0025] refer to Figures 1-5As shown, a housing 9 is fixedly installed on the top surface of the hopper 1. A bearing seat 10 is fixedly installed on the top surface of the hopper 1 within the housing 9. An outer rod 11 is fixedly installed through the middle of the bearing seat 10. Multiple stirring blades 16 are fixedly installed on the outer surface of the outer rod 11. A second drive gear 17 is fixedly installed near the top of the outer rod 11. A second motor 18 is fixedly installed on the top surface of the housing 9. The drive end of the second motor 18 extends into the interior of the housing 9. A connecting gear 19 is fixedly installed on the drive end of the second motor 18, and the connecting gear 19 meshes with the second drive gear 17. The housing 9 protects the internal transmission components, prevents raw material dust from entering and affecting the equipment's lifespan, and avoids operator contact with moving parts, thus improving safety. The outer rod 11 is stably supported by the bearing seat 10, reducing the shaking of the outer rod 11 during rotation and ensuring the mixing effect of the stirring blades 16. The multiple stirring blades 16 can mix the raw materials in the hopper 1 in all directions, effectively breaking up the raw material lumps (especially Chinese medicine raw materials are prone to lumping due to the presence of gelatinous components), making the raw materials loose and uniform, and avoiding the discharge obstruction caused by lumps. The motor 18 can drive the meshing transmission between the connecting gear 19 and the driving gear 17, thereby driving the outer rod 11 to rotate. The mixing speed can be controlled by adjusting the speed of the motor 18. For highly viscous raw materials, the speed can be increased to enhance the mixing effect, and for easily broken raw materials, the speed can be reduced to reduce losses.

[0026] refer to Figures 1-5 As shown, an inner rod 12 is provided in the middle of the outer rod 11, and a connecting rod 13 is fixedly installed at the bottom end of the inner rod 12. One end of the connecting rod 13 extends into the interior of the discharge pipe 2, and a spiral conveying blade 14 is fixedly installed on the outer surface of the end of the connecting rod 13 extending into the discharge pipe 2. A drive mechanism 15 connected to the inner rod 12 is provided inside the housing 9. Through the nested structure of the outer rod 11 and the inner rod 12, the stirring and conveying can be operated independently without interference. The stirring and conveying speeds can be adjusted according to the state of the raw materials, improving operational flexibility. The connecting rod 13 facilitates the transmission of power from the inner rod 12 to the spiral conveying blade 14. The gap between the spiral conveying blade 14 and the inner wall of the discharge pipe 2 is small, which can stably and evenly push the raw materials in the hopper 1 to the metering tube 3, ensuring the continuity and stability of the feeding, which is especially suitable for conveying granular and powdered raw materials.

[0027] refer to Figures 1-5As shown, the drive mechanism 15 includes a bearing 1501, a drive gear 1502, a motor 1503, and a pinion 1504. The bearing 1501 is fixedly mounted on the inner top surface of the housing 9. The top end of the inner rod 12 is fixedly mounted in the middle of the bearing 1501. The drive gear 1502 is fixedly mounted on the outer surface of the inner rod 12 near its top end. The motor 1503 is fixedly mounted on the top surface of the housing 9. The drive end of the motor 1503 extends into the interior of the housing 9. A pinion 1504 is fixedly mounted on the drive end of the motor 1503. The pinion 1504 meshes with the drive gear 1502. The motor 1503 drives the pinion 1504 to rotate, and the meshing transmission between the pinion 1504 and the drive gear 1502 drives the inner rod 12 to rotate. By controlling the rotation angle and speed of the motor 1503, the conveying amount of the spiral conveying blade 14 can be precisely controlled. With the feedback from the weighing sensor 7, a segmented conveying mode of fast coarse conveying + slow fine conveying can be realized, further improving the quantitative accuracy.

[0028] The implementation principle of an embodiment of a raw material dispensing device of this application is as follows: During operation, the raw material enters the hopper 1 through the feed pipe 23. At this time, the operator can start the second motor 18, which drives the connecting gear 19 to rotate. The connecting gear 19 meshes with the second drive gear 17, thereby driving the outer rod 11 to rotate under the support of the bearing seat 10. The stirring blades 16 on the outer rod 11 rotate synchronously to stir the raw material in the hopper 1, prevent agglomeration, and ensure uniformity of the raw material. At the same time, the first motor 1503 starts, and the drive end drives the pinion 1504 to rotate. The pinion 1504 meshes with the first drive gear 1502, driving the inner rod 12 to rotate under the support of the bearing 1501. The inner rod 12 drives the spiral conveying blades 14 to rotate in the discharge pipe 2 through the connecting rod 13, continuously dispensing the raw material in the hopper 1. The raw material is evenly pushed into the quantitative tube 3. The weight of the raw material in the quantitative tube 3 is transmitted to the weighing sensor 7 through the support rod 8. The weighing sensor 7 transmits the weight signal to the control system in real time. When the weight is close to the preset value, the control system controls the motor 1503 to decelerate and perform slow and precise feeding. When the preset dispensing amount is reached, the motor 1503 stops, the spiral conveyor blade 14 stops feeding, and then the telescopic cylinder 21 starts, driving the U-shaped plate 6 and the discharge pipe 5 to move downward, so that the discharge pipe 5 is aligned with the receiving container below. This device can realize the independent operation of stirring and conveying without interference. Through the cooperation of the weighing sensor 7 and the motor 1503, the raw material can be effectively quantitatively dispensed. At the same time, it can avoid problems such as leakage of raw material during the dispensing process and improve the dispensing quality of raw material.
