Description

Technical Field

[0001] This application relates to the field of medical auxiliary equipment technology, and in particular to a device for dispensing pharmaceutical powder, specifically a device that can automatically dispense and dispense powdered pharmaceutical products in equal portions. Background Technology

[0002] Common oral medications generally come in tablet, powder, and liquid forms. The dosage typically varies depending on the specific condition. This is especially true for pediatric medications, which require dosage adjustments based on age, weight, and other factors. Therefore, pre-packaged medications are an essential means of meeting people's daily needs.

[0003] Currently, there are two main methods for evenly distributing medicine powder: one is to divide the medicine into multiple compartments, feed the medicine into each compartment separately, read the distribution results, and manually repeat the distribution process to complete the even distribution; the other is to determine the distribution results using a weighing sensor, and then complete the even distribution of the medicine powder.

[0004] Of course, the existing powder dispensing devices are not limited to the two methods mentioned above. They are mainly designed for dispensing large doses of medicines, and their accuracy range is limited. In addition, some require repetitive manual operations, resulting in low dispensing efficiency. Therefore, the existing powder dispensing methods cannot meet the needs of dispensing small doses of powder medicines, whether in terms of efficiency or accuracy.

[0005] Therefore, it is urgent to propose a new technical solution to address the problems existing in the current technology. Utility Model Content

[0006] This application provides a powder dispensing device to solve the problem that existing powder dispensing technologies cannot meet the accuracy requirements for dispensing small doses of powder.

[0007] To achieve the above objectives, this application provides the following technical solution:

The discharge port of the feeding trough is located above the dispensing turntable, and a sensor is provided on the edge of the dispensing turntable near the discharge port. The turntable drive assembly includes a motor and a transmission component connected to the output shaft of the motor, which drives the dispensing turntable to rotate. The scraping assembly includes a dispensing scraper and a scraping drive component, which drives the dispensing scraper to contact or move away from the dispensing turntable. A brush head is provided on the dispensing scraper, and the dispensing turntable rotates relative to the dispensing scraper by a target angle, causing the powder to accumulate on one side of the dispensing scraper. The dispensing scraper scrapes part of the accumulated powder into the collector through the brush head.

[0009] The feeding chute is inclined horizontally toward the discharge port.

[0010] The sensor, electromagnetic oscillator, motor, and scraper drive are all connected to the controller signal.

[0011] In the preferred embodiment of the above technical solution, the feeding trough is used to hold the powdered medicine to be dispensed. The feeding trough is a long strip-shaped trough structure with a discharge port at one end.

[0012] Preferably, an electromagnetic oscillator is provided below the feeding trough. The electromagnetic oscillator is mounted on the base plate through a shock-absorbing structure, which includes a spring. The base plate forms a mounting base for the oscillating feeding assembly, the feeding turntable, the turntable drive assembly, the scraping assembly, and the collector.

[0013] Preferably, a mounting through hole is formed on the base plate, and the scraper assembly and collector are both installed in the mounting through hole.

[0014] Preferably, the material distribution turntable is a disc with a structural hole in the middle. The structural hole is located above and communicates with the mounting through hole. The scraping component passes through the structural hole and is adapted to and connected to the material distribution turntable. The collector is located below the structural hole and close to the edge of the structural hole. The collector is set correspondingly to the material distribution scraper.

[0015] Preferably, the transmission component includes a drive gear, a turntable gear meshing with the drive gear, and a rolling bearing rotating with the turntable gear; the drive gear is connected to the output shaft of the motor, and the drive gear and the rolling bearing are arranged opposite to each other on both sides of the material distribution turntable.

[0016] Preferably, the turntable gear is located below the material distribution turntable and is tightly connected to the material distribution turntable by screws.

[0017] Preferably, the sensor is used to detect whether powder is falling. When the sensor does not detect powder falling, the sensor outputs a signal to the controller, the controller sends a signal to the electromagnetic oscillator, and the electromagnetic oscillator stops oscillating.

[0018] Preferably, the scraping drive includes a driver and a lifting arm with one end connected to the output end of the driver. The other end of the lifting arm is equipped with a distributing scraper and a drive motor. The drive motor is used to drive the brush head to rotate along the side wall of the distributing scraper. During the rotation, a portion of the medicine near the side wall of the distributing scraper is scraped into the collector.

[0019] Preferably, the material distribution scraper is a plate that is perpendicular to the surface of the material distribution turntable.

[0020] Preferably, the brush head is a silicone brush head, which is a plate installed on one side of the distributing scraper. One end of the brush head is located in the middle of the distributing scraper and is connected to the drive motor, while the other end is flush with the edge of the distributing scraper. The distributing scraper is disc-shaped.

[0021] Preferably, the driver is used to drive the lifting arm to move up and down, thereby driving the material distribution scraper to move up and down, so that the bottom of the material distribution scraper abuts against the material distribution turntable, or so that the material distribution scraper rises from the surface of the material distribution turntable.

[0022] Compared with the prior art, this application has the following advantages:

[0023] 1. This application provides a powder dispensing device, which mainly includes a vibrating feeding assembly, a dispensing turntable, a turntable driving assembly, a scraping assembly, a collector, and a controller; the vibrating feeding assembly mainly includes a feeding trough and an electromagnetic vibrator, which drives the feeding trough to vibrate and dispense powder onto the dispensing turntable; the dispensing turntable is driven to rotate at a uniform speed, so that the powder is evenly distributed onto the dispensing turntable; the scraping assembly includes a dispensing scraper and a scraping driving component, the dispensing scraper is a plate perpendicular to the surface of the dispensing turntable, and when the dispensing scraper abuts against the dispensing turntable, it moves with the dispensing turntable... The rotating feeder scraper stops the material. When the feeder turntable rotates to the target angle, it stops. At this point, the feeder scraper intercepts part of the medicine, and then the brush head on the feeder scraper pushes part of the medicine into the collector. Since the medicine on the feeder turntable is evenly distributed in this application, the angle of rotation of the feeder turntable each time can be set, thereby controlling the amount of material piled on the side of the feeder scraper after the feeder turntable stops rotating. After the material piles up, the cross-sectional area of ​​the brush head is fixed, and the amount of medicine it can push in is fixed. Therefore, it can be ensured that the amount of material pushed in each time is basically the same, which meets the accuracy of small-dose powder medicine dispensing.

[0024] 2. The powder dispensing device provided in this application eliminates manual observation and achieves better powder packaging and improves efficiency through mechanical structure control. During the process, electromagnetic oscillation causes the powder to fall continuously onto the rotating dispensing turntable. By controlling the feeding speed and the rotation speed of the dispensing turntable, the powder can be evenly distributed on the turntable. After feeding, the scraping component performs a certain action to evenly package the powder, reducing multiple contacts in the device that may cause residue, meeting the requirements for small-dose drug packaging, and making the dispensing results more accurate.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order).

[0031] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0032] To address the problems existing in the prior art, this application provides a powder dispensing device. This device mainly includes a vibrating feeding assembly, a dispensing turntable 10, a turntable drive assembly, a scraping assembly, a collector, and a controller. The device has a simple overall structure, high dispensing efficiency, and can meet the dispensing accuracy requirements for small-dose powdered drugs. The structural principles of each part of the powder dispensing device provided in this application are described in detail below.

[0033] I. Vibrating Feeding Component

[0034] The vibrating feeding assembly mainly includes a feeding trough 4 and an electromagnetic vibrator 1. The electromagnetic vibrator 1 is located below the feeding trough 4 and is mounted on the base plate 3 via a spring 2 that has a shock-absorbing function. The electromagnetic vibrator 1 can drive the feeding trough 4 to vibrate and feed materials to the material distribution turntable 10.

[0035] The feeding trough 4 contains powdered medicine to be distributed. The feeding trough 4 is a long strip-shaped trough structure with a discharge port at one end. The feeding trough 4 is inclined in the horizontal direction toward the discharge port. In this way, when vibrating, the medicine falls down the slope of the feeding trough 4 onto the distribution turntable 10.

[0036] The installation slope of the feeding trough 4 in this application can be determined according to actual usage requirements, and this application does not impose any restrictions on the installation slope of the feeding trough 4.

[0037] During the specific manufacturing and installation, the main body of the vibrating feeding component can be welded from 304 stainless steel. A stainless steel base plate 3 is welded to its bottom and fixed together with the spring 2 below by screws. This ensures that when the electromagnetic oscillator 1 is in working condition, the lower half of the vibrating feeding component is stable and does not shake, and will not affect the material distribution turntable 10, etc. In addition, the bottom of the feeding trough 4 is tightly connected to the electromagnetic oscillator 1.

[0038] In order to control the opening and closing of the electromagnetic oscillator 1, a sensor 5 is installed on the edge of the distribution turntable 10 near the discharge port. The sensor 5 can detect whether powder is falling. When the sensor 5 does not detect any powder falling, that is, all the medicine in the feeding trough 4 has been fed onto the distribution turntable 10, at this time, the sensor 5 outputs a signal to the controller, and the controller sends a signal to the electromagnetic oscillator 1, thereby controlling the electromagnetic oscillator 1 to stop oscillating.

[0039] It should be noted that initially, the electromagnetic oscillator 1 starts to oscillate and feed the material. When the sensor 5 detects that the medicine is falling, the sensor 5 sends a signal to the controller, and the controller controls the material distribution turntable 10 to rotate. The material distribution turntable 10 rotates at a constant speed so that the powder falls evenly on the material distribution turntable 10.

[0040] II. Material Distribution Turntable 10

[0041] In this embodiment, the vibrating feeding component, the material distribution turntable 10, the turntable driving component, the scraping component, and the collector can be integrated and mounted on the base plate 3.

[0042] In a preferred embodiment, mounting through holes are formed on the base plate 3, and both the scraper assembly and the collector are installed in the mounting through holes. Accordingly, to achieve structural and functional adaptation and reduce the size of the equipment, the material distribution turntable 10 can be designed as a disc with a structural hole in the center, such as... Figure 1 The structural hole is located above and communicates with the mounting through hole. The scraper assembly passes through the structural hole and is adapted and connected to the material distribution turntable 10. The collector is located below the structural hole and close to its edge, and is correspondingly set with the material distribution scraper 7. The material distribution turntable 10 is located below the discharge port of the discharge trough 4. This structural arrangement not only improves the integration of the device but also achieves a reasonable layout of the structure.

[0043] To drive the material distribution turntable 10, a turntable drive assembly is installed on the base plate 3.

[0044] In this embodiment, the turntable drive assembly includes a motor and a transmission component connected to the output shaft of the motor. The transmission component drives the material distribution turntable 10 to rotate. The transmission component includes a power gear 12 connected to the output shaft of the motor, a turntable gear 8 meshing with the power gear 12, and a rolling bearing 9 rotatably engaging with the turntable gear 8. The power gear 12 and the rolling bearing 9 are arranged opposite to each other on both sides of the material distribution turntable 10. The edge of the material distribution turntable 10 rests on the rolling bearing 9 fixed to the base plate 3.

[0045] In this embodiment, the turntable gear 8 is located below the material distribution turntable 10 and is tightly connected to the material distribution turntable 10 by screws. Therefore, the motor sequentially drives the power gear 12, the turntable gear 8, and the rolling bearing 9, thereby realizing the rotation drive of the material distribution turntable 10.

[0046] In this embodiment, the motor driving the dispensing turntable 10 is connected to the controller signal. For example, the electromagnetic oscillator 1 oscillates and starts dispensing. When the sensor 5 detects that the medicine is falling, the sensor 5 sends a signal to the controller, and the controller outputs a control signal to the motor. The motor starts and drives the dispensing turntable 10 to rotate. The dispensing turntable 10 rotates at a uniform speed so that the powder falls evenly on the dispensing turntable 10.

[0047] III. Scraper Component

[0048] The scraping assembly includes a distributing scraper 7 and a scraping drive component. The scraping drive component drives the distributing scraper 7 to contact with or move away from the distributing turntable 10. The distributing scraper 7 is a plate perpendicular to the surface of the distributing turntable 10. When the distributing scraper 7 abuts against the distributing turntable 10, it blocks the material as the turntable 10 rotates. When the turntable 10 stops rotating after rotating to the target angle, the distributing scraper 7 intercepts part of the medicine, and then the brush head 13 on the distributing scraper 7 pushes part of the medicine into the collector. Since the medicine on the distributing turntable 10 is uniformly distributed in this application, as long as the angle of rotation of the distributing turntable 10 is set, the amount of material piled on the side of the distributing scraper 7 after the turntable 10 stops rotating can be controlled. After the material piles up, the cross-sectional area of ​​the brush head is constant, and the amount of medicine that can be pushed in is constant. Therefore, it can be ensured that the amount of material pushed in each time is basically the same, which meets the dispensing accuracy of small-dose powder medicine.

[0049] In this embodiment, the scraping drive includes a driver and a lifting arm 11 with one end connected to the output end of the driver. The other end of the lifting arm 11 is equipped with a distributing scraper 7 and a drive motor. The drive motor is used to drive the brush head to rotate along the side wall of the distributing scraper 7. During the rotation, a portion of the medicine near the side wall of the distributing scraper 7 is scraped into the collector.

[0050] In this embodiment, the driver can be a drive motor or a drive cylinder. When the driver is a drive cylinder, the drive cylinder can be set vertically. When the controller controls the drive cylinder to move, the lifting arm 11 moves vertically up and down under the drive of the drive cylinder, thereby driving the material distribution scraper 7 to move up and down, so that the bottom of the material distribution scraper 7 abuts against the material distribution turntable 10, or so that the material distribution scraper 7 rises from the surface of the material distribution turntable 10.

[0051] When the driver is a drive motor, the drive motor can be set horizontally, and the lifting arm 11 is installed on the motor shaft of the drive motor. When the controller controls the rotation of the motor shaft, the lifting arm 11 rotates around the center of the motor shaft. At this time, the other end of the lifting arm 11 can also be raised and lowered, thereby driving the material distribution scraper 7 to move up and down, so that the bottom of the material distribution scraper 7 abuts against the material distribution turntable 10, or so that the material distribution scraper 7 rises from the surface of the material distribution turntable 10.

[0052] In this embodiment, the dispensing scraper 7 can be disc-shaped, the brush head is a silicone brush head, and the brush head 13 is a plate installed on one side of the dispensing scraper 7. One end of the brush head 13 is located in the middle of the dispensing scraper 7 and is connected to the drive motor. The drive motor is used to drive the brush head 13 to rotate along the side wall of the dispensing scraper 7. The other end of the brush head 13 is flush with the edge of the dispensing scraper 7. During the rotation of the brush head 13, a portion of the medicine near the side wall of the dispensing scraper 7 is scraped into the collector.

[0053] IV. Controller

[0054] The controller described in this application is an automatic control device used to control the sequential actions of various actuators. It can utilize existing control devices. The controller can be installed in a distribution box, and its central processing unit can be a PLC and a touch screen. The PLC, connected to the touch screen, can perform functions such as opening and closing the panel control system, setting stop parameters, and adjusting operating speed. It can also display internal data such as system operating status and alarm causes in real time. Manual control and individual control can be achieved via automatic switching buttons to meet other usage requirements.

[0055] V. Collector

[0056] The collector in this application can be any smooth trough or plate structure. Of course, in this embodiment, a smooth-surfaced funnel 6 is preferred. A conveyor belt can also be set below the collector, and several medicine bottles are placed on the conveyor belt in sequence. The medicine powder output from the collector can be directly loaded into the medicine bottles, and the medicine bottles are then transported to the next workstation by the conveyor belt. The conveying speed of the conveyor belt can be controlled according to the action interval of the distributing scraper 7.

[0057] The following describes the usage process of the powdered drug dispensing device provided in this application.

[0058] After the powdered medicine to be dispensed is poured into the feeding trough 4, the feeding trough 4 generates high-frequency oscillation under the drive of the electromagnetic oscillator 1. The feeding trough 4 is tilted at a certain angle in the horizontal direction towards the discharge port. Under the action of high-frequency oscillation, the medicine moves continuously from the middle and rear of the feeding trough 4 towards the front discharge port until it falls onto the dispensing turntable 10. At this time, the sensor 5 detects the falling medicine and sends a signal back. The electromagnetic oscillator 1 continues to oscillate. During the falling of the medicine powder, the dispensing turntable 10 rotates continuously under the action of the motor. The medicine powder evenly covers the surface of the dispensing turntable 10. After there is no more medicine powder falling in the feeding trough 4, the sensor 5 can no longer detect the falling medicine powder and sends this signal back. The electromagnetic oscillator 1 stops working, and the dispensing action is completed.

[0059] After the upper oscillating feeding component evenly distributes the required amount of medicine onto the distributing turntable 10, the distributing scraper 7, driven by the lifting arm 11, falls from above the mechanism until it comes into contact with the distributing turntable 10. At this point, the distributing scraper 7 and the distributing turntable 10 are perpendicular to each other, and the edge of the distributing scraper 7 is tightly attached to the distributing turntable 10. The power gear 12 rotates under the action of the motor, and through the cooperation between the gears, it drives the turntable gear 8 to rotate. Since the distributing turntable 10 and the turntable gear 8 are tightly connected by screws, the distributing turntable 10 also rotates accordingly. Because the edge of the distributing turntable 10 is supported on the rolling bearing 9 fixed to the base plate, the middle part of the distributing turntable 10 and the turntable gear 8 is in a suspended state, which can be used to install components such as collectors. By controlling the motor driving the dispensing turntable, the dispensing turntable 10 stops rotating after rotating through a certain angle according to different packaging requirements. Some of the powder is blocked in front of the funnel 6 by the dispensing scraper 7. The dispensing scraper 7 is driven to rotate one revolution in the vertical plane, or the dispensing scraper 7 is stationary so that the brush head on it rotates one revolution along the dispensing scraper 7. The powder is scraped into the funnel 6 by the silicone brush head, and the collection device below completes the collection of the powder. During the process, the rotation angle of the dispensing turntable 10 can be set (actively set by the user according to the amount of powder required) to ensure that the amount of powder is consistent each time. The dispensing turntable 10 stops rotating and scrapes the powder after rotating a certain angle. This process is repeated until the powder is evenly distributed.

[0060] Existing technologies have certain shortcomings in the uniform distribution of drug powder, relying on human observation and measurement results in large errors, and are also insufficient in terms of precision for small doses of drug powder.

[0061] Compared with existing technologies, the powder dispensing device provided in this application eliminates the need for manual observation and achieves better powder packaging through mechanical structure control, thereby improving efficiency. During the process, electromagnetic oscillation causes the powder to continuously fall onto the rotating dispensing turntable. By controlling the feeding speed and the rotation speed of the dispensing turntable, the powder can be evenly distributed on the turntable. After feeding, the scraping component performs a certain action to evenly package the powder, reducing multiple contacts in the device that may cause residue, meeting the requirements for small-dose drug packaging, and making the dispensing results more accurate.

[0062] During the scraping process, when the distributing scraper comes into contact with the distributing turntable, the scraper blocks the material as the turntable rotates. When the turntable stops rotating at the target angle, the scraper has intercepted a portion of the medication. Then, a brush head on the scraper pushes some of the medication into the collector. Since the medication on the turntable is basically evenly distributed, the amount of material piled on the side of the scraper after the turntable stops can be controlled by setting the angle of rotation for each rotation. With a fixed cross-sectional area of ​​the brush head after the pile, the amount of medication it can push in is also fixed. Furthermore, the scraping action of the brush head is mechanically controlled, ensuring consistent scraping action each time, thus guaranteeing that the amount of medication pushed in each time is essentially the same. Factory testing shows that the dispensing accuracy of this powder medication dispensing device meets the dispensing accuracy requirements for small-dose powder medications on the market.

[0063] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0064] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
