Description

Technical Field

[0001] This utility model relates to the field of drug granule packaging technology, specifically to an automatic drug granule metering and packaging machine. Background Technology

[0002] The pharmaceutical industry has increasingly stringent requirements for drug quality and production efficiency. As an important raw material for various dosage forms such as tablets and capsules, the packaging of drug granules is of paramount importance.

[0003] Publication No. CN220905475U discloses a granule packaging machine for pharmaceutical production, including a main body, an unwinding assembly, a three-side sealing assembly, and a sealing assembly. Two drive rollers are located on the top of the main body to guide the movement of the packaging bags. A feeding mechanism is fixedly connected to the rear of the top of the main body, and a feeding mechanism for precise feeding is located in front of the support frame. A feeding adjustment assembly is located below the feeding mechanism. The feeding mechanism includes a fixed plate, which is fixedly connected to the front of the support frame. A hopper is fixedly connected to the front of the fixed plate, and a drive motor is fixedly connected to the back of the fixed plate. When feeding pharmaceutical granules from the hopper, the feeding mechanism can accurately control the amount of granules fed, ensuring that the weight of granules in each bag is the same after packaging, thus improving the practicality of the device.

[0004] As shown in the above technical solution, although the device can ensure that the weight of each bag of granules is the same through the feeding mechanism, it cannot guarantee that the number of granules in each can is equal. It can only determine the standard quantity of each can by the canning time and canning weight. This means that when it is necessary to accurately control the number of granules in the canning process, manual intervention is required to ensure that the number of granules in each can is equal, which is time-consuming and labor-intensive.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1-4This utility model provides the following two technical solutions:

[0028] First embodiment: An automatic drug granule metering and packaging machine, comprising:

[0029] Packaging unit 1 is used to receive metered drug granules and encapsulate them into independent packaging units. A connector 2 is fixedly installed on the top of the packaging unit 1. The lower end of the inner wall of the connector 2 is shaped like a frustum with a wider top and a narrower bottom.

[0030] The feed pipe 3 and the discharge pipe 4 are fixedly installed on the top of the connector 2 and the discharge pipe 4 is fixedly installed between the packager 1 and the connector 2. The feed pipe 3 is used to transport the drug granules to be measured into the interior of the connector 2 and the discharge pipe 4 is used to transport the measured drug granules from the connector 2 into the packager 1.

[0031] Metering component 5 is installed inside connector 2. Metering component 5 includes mounting cylinder 51, which is fixedly installed between connector 2 and discharge pipe 4. Connector 2 has a plurality of centrally symmetrically distributed mounting slots 52. Each of the mounting slots 52 has a particle passage cylinder 53 installed in it. Each particle passage cylinder 53 includes a first passage cylinder 531 and a second passage cylinder 532. The first passage cylinder 531 is fixedly installed at the particle passage cylinder 53, and the second passage cylinder 532 is fixedly installed on the top of the first passage cylinder 531. The second passage cylinder 532 is semi-circular in shape and has a passage groove 533 on it to facilitate the entry of drug particles into the first passage cylinder 531. An mounting ring 54 is installed inside mounting cylinder 51, and an infrared metering device 55 is installed inside the mounting ring 54. Metering component 5 is used to meter the drug particles flowing into packaging unit 1.

[0032] Control component 6 is installed inside metering component 5 and is used to control the working status of metering component 5.

[0033] The drug particles to be metered enter the connector 2 through the feed pipe 3. Because the lower end of the inner wall of the connector 2 is a frustum shape (wider at the top and narrower at the bottom), this structure helps the drug particles move smoothly downwards, reducing particle accumulation within the connector 2 and allowing the particles to enter the subsequent metering assembly 5 more smoothly. Multiple particle tubes 53 are evenly distributed within the mounting groove 52 of the connector 2. The drug particles enter the first tube 531 from the groove 533 on the second tube 532, and then enter the mounting tube 51. The infrared metering device 55 within the mounting ring 54 counts and measures the passing drug particles using infrared sensing technology. The infrared metering device 55 can measure according to the set metering standards. The system accurately measures the number of drug particles entering the packaging unit 1. The control component 6 is installed inside the metering component 5. It can receive the metering data from the infrared metering device 55. When the preset metering value is reached, the control component 6 controls the working state of the metering component 5, closes the channel of the particle tube 53, and prevents the drug particles from continuing to flow into the packaging unit 1. When it is necessary to continue metering, the control component 6 opens the metering component 5, allowing the drug particles to continue to enter the packaging unit 1 through the particle tube 53. The metered drug particles enter the packaging unit 1 through the discharge pipe 4. The packaging unit 1 encapsulates these drug particles into independent packaging units, completing the automatic metering and packaging process of the drug particles.

[0034] In this embodiment, the metering component 5 can accurately count and measure the drug particles, ensuring that the number of drug particles in each packaging unit meets the specified requirements, thereby improving the quality and accuracy of drug packaging. The control component 6 automatically controls the working state of the metering component 5 based on the metering data, without the need for manual intervention, thus realizing automatic metering and packaging of drug particles, improving production efficiency, and reducing the errors and instabilities that may be caused by manual operation.

[0035] The second embodiment differs from the first embodiment in that the control component 6 includes a first elevator 61, which is fixedly installed inside the mounting cylinder 51. A first stop 62 is fixedly installed at the output end of the first elevator 61. The first stop 62 is slidably installed at the end of a plurality of particle tubes 53. A second elevator 63 is fixedly installed at the top of the first elevator 61. The output end of the second elevator 63 passes through the first elevator 61 and is fixedly installed with a second stop 64. The second stop 64 is slidably installed at the end of one of the particle tubes 53. A groove 65 is provided on the first elevator 61, and the second stop 64 is slidably installed in the groove 65.

[0036] The connecting part 2 is equipped with a stirring assembly 7, which includes a turntable 71. The turntable 71 is rotatably mounted on the inner top of the connecting part 2. Multiple mounting rods 72 are evenly mounted on the bottom of the turntable 71 in a centrally symmetrical manner. Two stirring spoons 73 are fixedly mounted on the mounting rods 72. A motor 74 is fixedly mounted on the top of the connecting part 2. The output end of the motor 74 passes through the connecting part 2 and is fixedly connected to the turntable 71.

[0037] One of the stirring spoons 73 on the mounting rod 72 is rotatably mounted at the through groove 533, and the other stirring spoon 73 is rotatably mounted at the gap between the second through cylinder 532 and the mounting cylinder 51.

[0038] When the first elevator 61 is working, it can drive the first stop 62 to move up and down. The movement of the first stop 62 can control the opening and closing of the granule tube 53, thereby controlling whether the drug granules can pass through the granule tube 53 and enter the mounting tube 51. The second elevator 63 is fixed to the top of the first elevator 61, and its output end passes through the first elevator 61 to fix the second stop 64. The second stop 64 is slidably installed at the end of one of the granule tubes 53. The second elevator 63 can drive the second stop 64 to move up and down. The movement of the second stop 64 can control the opening and closing of one of the granule tubes 53 individually. The slide groove 65 on the first elevator 61 is used to limit the movement of the second stop 64. The direction ensures the stability of the movement of the second stop 64; when the motor 74 is working, it can drive the turntable 71 to rotate. Multiple mounting rods 72 evenly installed at the bottom of the turntable 71 will rotate with the turntable 71, and the stirring spoons 73 on the mounting rods 72 will also rotate. One of the stirring spoons 73 is rotatably installed at the through groove 533, which can stir the drug particles entering the granule tube 53, so that the drug particles can pass through the through groove 533 more smoothly into the first tube 531. The other stirring spoon 73 is rotatably installed at the gap between the second tube 532 and the mounting tube 51, which can stir the drug particles at the gap, prevent the drug particles from accumulating at this place, and ensure the smooth flow of drug particles.

[0039] In this embodiment, the movement of the first stop 62 and the second stop 64 is controlled by the first elevator 61 and the second elevator 63 respectively, which can realize the on / off control of multiple particle tubes 53 and the individual control of one particle tube 53. This allows for precise adjustment of the number of drug particles entering the mounting cylinder 51, further improving the accuracy of metering. The positions of the first stop 62 and the second stop 64 can be flexibly controlled according to different metering requirements to adapt to the metering of drug particles of different specifications, thus improving the applicability of the equipment. The stirring spoon 73 stirs the drug particles at the passage 533 and the gap between the second passage 532 and the mounting cylinder 51, which can effectively prevent the accumulation and blockage of drug particles in these parts, ensuring that the drug particles can pass smoothly through the metering component 4 and improving the stability of equipment operation.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] In use, the drug granules to be measured are poured into the feed pipe 3. Under the action of gravity, the drug granules enter the connector 2 along the feed pipe 3. Because the lower end of the inner wall of the connector 2 is a frustum shape that is wider at the top and narrower at the bottom, the drug granules will move smoothly downwards and be evenly dispersed into multiple particle tubes 53. The drug granules enter the first tube 531 through the through groove 533 on the second tube 532, and then enter the mounting tube 51. The infrared metering device 55 in the mounting ring 54 monitors the passing drug granules in real time, and counts and measures the granules using infrared sensing technology for precise measurement. The control component 6 accurately measures the number of drug particles entering the packaging unit 1; the control component 6 receives the measurement data from the infrared meter 55 in real time. When the measurement data reaches the preset number of drug particles for each packaging unit, the first elevator 61 is activated, driving the first stop 62 to move downward, closing the channels of multiple particle tubes 53, and preventing drug particles from continuing to flow into the packaging unit 1; at the same time, if it is necessary to control a certain particle tube 53 individually, the second elevator 63 can drive the second stop 64 to move, opening or closing the corresponding particle tube 53. When a packaging unit is completed... When the metering is complete and another metering cycle is required, the control component 6 controls the first elevator 61 and the second elevator 63 to move the first stop 62 and the second stop 64 upwards, reopening the channel of the granule tube 53 and allowing the drug granules to continue passing through the granule tube 53 into the packaging unit 1. During the feeding and metering process, the motor 74 works continuously, driving the turntable 71 to rotate. The mounting rod 72 and stirring spoon 73 at the bottom of the turntable 71 rotate accordingly. The stirring spoon 73 located at the channel 533 stirs the drug granules entering the granule tube 53, promoting the smooth passage of the granules through the channel 533 into the first tube 531. The stirring spoon 73 located at the gap between the second tube 532 and the mounting tube 51 stirs the drug granules at the gap to prevent granule accumulation and ensure smooth flow of the drug granules. The precisely metered drug granules enter the packaging unit 1 through the discharge pipe 4. The packaging unit 1 packages the drug granules into independent packaging units according to the preset packaging specifications, completing one automatic metering and packaging process for drug granules. Repeating the above steps can realize continuous automated drug granule metering and packaging operations.
