Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a dispensing device for traditional Chinese medicine powder. Background Technology

[0002] In the field of traditional Chinese medicine, with the increasing recognition of the efficacy of traditional Chinese medicine and the acceleration of the modernization process of Chinese medicine, the production scale of Chinese medicine preparations is expanding day by day. As the basic raw material form of many Chinese medicine dosage forms (such as powders, pills, capsules, etc.), the packaging of Chinese medicine powder occupies a pivotal position in the entire industrial chain. In the process of Chinese medicine production and processing, accurately packaging Chinese medicine powder into various containers is a crucial step.

[0003] Traditional dispensing devices often rely on manual control of the feeding amount or simply use valve opening and closing to achieve feeding, making it difficult to accurately control the dispensing amount of Chinese medicine powder. This can easily lead to significant weight deviations in the same batch of dispensed products, affecting the accuracy of the dosage of Chinese medicine. Therefore, we propose a dispensing device for Chinese medicine powder to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a dispensing device for traditional Chinese medicine powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dispensing device for traditional Chinese medicine powder includes a base, a turntable rotatably mounted on the top of the base, a plurality of placement slots on the top of the turntable, a dispensing cylinder for dispensing traditional Chinese medicine powder being movably placed in the placement slots, a rotation switching mechanism being provided between the turntable and the base, a traditional Chinese medicine cylinder being fixedly connected to the top of the base, a quantitative feeding mechanism being provided on the traditional Chinese medicine cylinder, and a controller being fixedly connected to one side of the base.

[0007] In a preferred embodiment of this invention, the quantitative feeding mechanism includes a hopper fixedly connected to the top of the herbal medicine cylinder, a drive motor fixedly connected to the top of the herbal medicine cylinder, and a rotating shaft rotatably connected to the top of the herbal medicine cylinder. The hopper is equipped with a stirring and scraping assembly. A feeding pipe is fixedly connected to the bottom of the hopper, and a solenoid valve is installed on the feeding pipe. An infrared sensor is fixedly connected to one inner wall of the herbal medicine cylinder. A driving gear is fixedly connected to the output shaft of the drive motor, and a driven gear is fixedly connected to the top of the rotating shaft. The driving gear and the driven gear mesh with each other. An installation ring is fixedly sleeved on the outer side of the rotating shaft, and multiple actuating plates are fixedly connected to the outer side of the installation ring. All actuating plates movably abut against the bottom inner wall of the herbal medicine cylinder. The height of the infrared sensor is greater than the height of the actuating plates. A scraper is fixedly connected to the rear inner wall of the herbal medicine cylinder, and the scraper movably abuts against the top of the actuating plates and the rear side of the rotating shaft.

[0008] As a preferred embodiment of this utility model, the bottom of the herbal medicine container is provided with a feeding port, and a feeding pipe is fixedly connected to the feeding port.

[0009] In a preferred embodiment of this invention, the rotating shaft is rotatably connected to the top of the herbal medicine cylinder via a bearing.

[0010] As a preferred embodiment of this utility model, the stirring and scraping assembly includes a rotary motor fixedly connected to the top of the hopper, a stirring shaft fixedly connected to the output shaft of the rotary motor, three stirring rods fixedly connected to both sides of the stirring shaft, a common scraper fixedly connected to the outer side of the three stirring rods on the same side, two scrapers respectively movably abutting against the inner walls of both sides of the hopper, and a feed pipe fixedly connected to the top of the hopper.

[0011] In a preferred embodiment of this invention, the rotation switching mechanism includes a servo motor and a reducer fixedly connected to the bottom of the base. The output shaft of the servo motor is fixedly connected to the input shaft of the reducer, and a rotating shaft is fixedly connected to the output shaft of the reducer. The top end of the rotating shaft is fixedly connected to the bottom of the turntable.

[0012] As a preferred embodiment of this utility model, the rotation switching mechanism further includes a limiting ring fixedly connected to the top of the base, the turntable is movably placed inside the limiting ring, the bottom of the limiting ring is provided with an annular groove, and the bottom of the turntable is rotatably connected with multiple balls, all of which are rolled and connected in the annular groove.

[0013] As a preferred embodiment of this utility model, both sides of the herbal medicine tube are fixedly connected to support seats, and both support seats are fixedly connected to the top of the base.

[0014] In this utility model, a dispensing device for traditional Chinese medicine powder is described. The powder is poured into a hopper through a feeding pipe. When dispensing is required, a rotary motor drives the rotation of a stirring shaft, stirring rod, and scraper. The stirring rod agitates the powder, improving its fluidity and ensuring more even and smooth feeding. Simultaneously, the scraper removes powder adhering to the inner wall of the hopper, preventing powder buildup and ensuring complete discharge. This facilitates subsequent cleaning and avoids powder waste. When an infrared sensor detects powder, indicating that the powder level is greater than the height of the agitator, the infrared sensor sends a signal to the controller, which then closes the solenoid valve and the rotary motor to stop dispensing.

[0015] In this utility model, a dispensing device for traditional Chinese medicine powder is described. When the drive motor is started, it drives the rotation of the active gear, which in turn drives the driven gear, rotating shaft, mounting ring, and multiple actuating blades to rotate backward. This conveys the traditional Chinese medicine powder between two actuating blades backward. When the powder reaches the scraper, the scraper scrapes the powder above the height of the actuating blades into the area between the two actuating blades, ensuring that the amount of powder falling into the discharge port and the discharge pipe is approximately equal. The powder is then dispensed into the dispensing cylinder, achieving quantitative dispensing. A servo motor and reducer drive the rotating shaft and turntable to rotate slowly, allowing the next dispensing cylinder to rotate directly below the discharge pipe for further dispensing of traditional Chinese medicine powder. A limiting ring, annular groove, and ball bearings guide and limit the turntable, making its rotation smoother and more stable.

[0016] This utility model has a reasonable structural design. The setting of stirring rod and scraper makes the feeding more uniform and smooth. At the same time, it can scrape off the Chinese medicine powder adhering to the inner wall of the hopper to ensure complete feeding. This not only facilitates later cleaning, but also avoids the waste of Chinese medicine powder. The setting of infrared sensor, solenoid valve, rotating actuating plate and scraper can distribute Chinese medicine powder to ensure that the packaged weight is close to consistent.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A dispensing device for traditional Chinese medicine powder includes a base 1, a turntable 6 rotatably mounted on the top of the base 1, a plurality of placement slots 7 on the top of the turntable 6, a dispensing cylinder 8 for dispensing traditional Chinese medicine powder being movably placed in the placement slots 7, a rotation switching mechanism 9 being provided between the turntable 6 and the base 1, a traditional Chinese medicine cylinder 3 being fixedly connected to the top of the base 1, a quantitative feeding mechanism 4 being provided on the traditional Chinese medicine cylinder 3, and a controller 5 being fixedly connected to one side of the base 1.

[0024] Furthermore, refer to Figures 1-3The quantitative feeding mechanism 4 includes a hopper 413 fixedly connected to the top of the medicine cylinder 3, a drive motor 41 fixedly connected to the top of the medicine cylinder 3, and a rotating shaft 44 rotatably connected to the top of the medicine cylinder 3. The hopper 413 is equipped with a stirring and scraping assembly. A feeding pipe 412 is fixedly connected to the bottom of the hopper 413, and a solenoid valve 411 is installed on the feeding pipe 412. An infrared sensor 410 is fixedly connected to the inner wall of one side of the medicine cylinder 3. A drive gear 42 is fixedly connected to the output shaft of the drive motor 41, and a driven gear 43 is fixedly connected to the top of the rotating shaft 44. The moving tooth 42 meshes with the driven tooth 43. An installation ring 45 is fixedly sleeved on the outer side of the rotating shaft 44. Multiple actuating plates 46 are fixedly connected to the outer side of the installation ring 45. The multiple actuating plates 46 are movably abutting against the inner wall of the bottom of the medicine cylinder 3. The installation position of the infrared sensor 410 is higher than the height of the actuating plates 46. A scraper 49 is fixedly connected to the inner wall of the rear side of the medicine cylinder 3. The scraper 49 movably abuts against the top of the actuating plates 46 and the rear side of the rotating shaft 44. A discharge port 47 is opened at the bottom of the medicine cylinder 3. A discharge pipe 48 is fixedly connected to the position of the discharge port 47.

[0025] Using the above scheme: When the infrared sensor 410 senses the Chinese medicine powder, it indicates that the height of the Chinese medicine powder is greater than the height of the agitator 46. The infrared sensor 410 sends a signal to the controller 5. The controller 5 closes the solenoid valve 411 and the rotary motor 414 to stop feeding, and then starts the drive motor 41. The drive motor 41 drives the rotation of the active gear 42. The active gear 42 drives the driven gear 43, the rotating shaft 44, the mounting ring 45 and the multiple agitators 46 to rotate backward, thereby conveying the Chinese medicine powder between the two agitators 46 backward. When it is conveyed to the point of contact with the scraper 49, the scraper 49 can scrape the Chinese medicine powder that is higher than the height of the agitator 46 into the area between the two agitators 46 behind, ensuring that the amount of Chinese medicine powder that finally falls into the feeding port 47 and the feeding pipe 48 is approximately equal, and finally it is packaged into the packaging cylinder 8, thereby achieving the purpose of quantitative packaging.

[0026] Furthermore, the rotating shaft 44 is rotatably connected to the top of the medicine cylinder 3 via a bearing, which improves the stability of the rotation of the rotating shaft 44.

[0027] Furthermore, refer to Figures 1-3 The agitation and scraping assembly includes a rotary motor 414 fixedly connected to the top of the hopper 413. A stirring shaft 415 is fixedly connected to the output shaft of the rotary motor 414. Three stirring rods 416 are fixedly connected to both sides of the stirring shaft 415. The same scraper 417 is fixedly connected to the outer side of the three stirring rods 416 on the same side. The two scrapers 417 are respectively movably abutting against the inner walls of both sides of the hopper 413. A feed pipe 418 is fixedly connected to the top of the hopper 413.

[0028] Using the above solution: the Chinese medicine powder can be poured into the hopper 413 through the feed pipe 418. When it needs to be dispensed, the rotating motor 414 drives the rotation of the stirring shaft 415, stirring rod 416 and scraper 417. The stirring rod 416 can stir the Chinese medicine powder, improve its fluidity, and make the feeding more uniform and smooth. At the same time, the scraper 417 can scrape off the Chinese medicine powder adhering to the inner wall of the hopper 413, avoiding the adhesion of Chinese medicine powder and the inability to completely discharge it. This not only facilitates later cleaning, but also avoids the waste of Chinese medicine powder.

[0029] Furthermore, refer to Figure 1 and Figure 4 The rotation switching mechanism 9 includes a servo motor 92 and a reducer 93 fixedly connected to the bottom of the base 1. The output shaft of the servo motor 92 is fixedly connected to the input shaft of the reducer 93. A rotating shaft 94 is fixedly connected to the output shaft of the reducer 93. The top end of the rotating shaft 94 is fixedly connected to the bottom of the turntable 6. The rotation switching mechanism 9 also includes a limiting ring 91 fixedly connected to the top of the base 1. The turntable 6 is movably placed in the limiting ring 91. An annular groove 96 is provided at the bottom of the limiting ring 91. Multiple balls 95 are rotatably connected to the bottom of the turntable 6. The multiple balls 95 are all rotatably connected in the annular groove 96.

[0030] The above solution is adopted: by setting the servo motor 92 and the reducer 93, the rotating shaft 94 and the turntable 6 can be driven to rotate slowly, so that the next dispensing cylinder 8 can be rotated directly below the feeding pipe 48 for further dispensing of Chinese medicine powder. By setting the limiting ring 91, the annular groove 96 and the ball bearing 95, the turntable 6 can be guided and limited, making its rotation more stable and smooth.

[0031] Furthermore, both sides of the medicine tube 3 are fixedly connected to support seats 2, and both support seats 2 are fixedly connected to the top of the base 1, which can support and fix the medicine tube 3.

[0032] In this invention, during use, the herbal powder is poured into the hopper 413 through the feed pipe 418. When dispensing is required, the rotary motor 414 drives the rotation of the stirring shaft 415, stirring rod 416, and scraper 417. The stirring rod 416 agitates the herbal powder, improving its fluidity and making the feeding more uniform and smooth. Simultaneously, the scraper 417 scrapes off the herbal powder adhering to the inner wall of the hopper 413, preventing powder buildup and ensuring complete discharge. This facilitates later cleaning and avoids waste of the herbal powder. When the infrared sensor 410 detects the herbal powder, indicating that the powder height is greater than the height of the agitator 46, the infrared sensor 410 sends a signal to the controller 5. The controller 5 closes the solenoid valve 411 and the rotary motor 414 to stop dispensing, and then starts the drive motor 41, which drives the active... The rotation of gear 42 drives the driven gear 43, rotating shaft 44, mounting ring 45 and multiple actuating plates 46 to rotate backward, thereby conveying the Chinese medicine powder between two actuating plates 46 backward. When it reaches the scraper 49, the scraper 49 scrapes the Chinese medicine powder that is higher than the height of the actuating plates 46 into the area between the two actuating plates 46 behind, ensuring that the amount of Chinese medicine powder that finally falls into the discharge port 47 and the discharge pipe 48 is approximately equal, and finally dispensed into the dispensing cylinder 8, thereby achieving the purpose of quantitative dispensing. Through the setting of servo motor 92 and reducer 93, the rotating shaft 94 and turntable 6 can be driven to rotate slowly, thereby rotating the next dispensing cylinder 8 directly below the discharge pipe 48 to continue dispensing Chinese medicine powder. Through the setting of limit ring 91, annular groove 96 and ball bearing 95, the turntable 6 can be guided and limited, making its rotation more stable and smooth.
