Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine dispensing technology, and in particular to a traditional Chinese medicine dispensing device and an automatic traditional Chinese medicine dispensing machine. Background Technology

[0002] Hospitals and pharmacies typically dispense Chinese herbal medicines in bulk, then fill them according to the patient's dosage. Traditionally, these bulk herbs are weighed manually, a method that is inefficient, prone to errors, and inconvenient for healthcare workers, while also increasing waiting times for patients.

[0003] Patent application number 202420358970.8 discloses an automatic dispensing machine for traditional Chinese medicine. However, this machine has several problems: 1. The dispensing power of the dispensing device is provided by a conveying spring. The cross-section of the conveying spring is rectangular, but the contact area with the traditional Chinese medicine is too small, causing it to spin idly during dispensing, resulting in low stability and accuracy; 2. When the traditional Chinese medicine is squeezed and conveyed by the conveying spring, the dispensing is initially slow due to the gradually narrowing of the outlet. However, as the dispensing speed of the dispensing rod becomes insufficient to fully dispense the traditional Chinese medicine at the outlet, it gradually accumulates, eventually causing all the accumulated traditional Chinese medicine at the outlet to be squeezed out. This results in an unstable decrease in weight, affecting weighing efficiency; 3. A horizontal stirring rod is located at the center of the dispensing rod during rotation. The stirring prevents the traditional Chinese medicine at the center of the dispensing rod from being effectively discharged, affecting dispensing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is: a Chinese herbal medicine dispensing device and an automatic Chinese herbal medicine dispensing machine. The dispensing machine can ensure the stability of Chinese herbal medicine dispensing during dispensing, reduce the occurrence of empty spinning during dispensing, thereby controlling the weight of the medicine dispensed and improving accuracy.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a traditional Chinese medicine dispensing device, including a medicine storage chamber, a medicine storage port on one side of the medicine storage chamber, and a medicine outlet on the other side of the medicine storage chamber. The medicine storage chamber is mounted on a weighing frame via a weighing device. The medicine storage chamber has a medicine storage chamber for placing traditional Chinese medicine and a conveying channel located below the medicine storage chamber. The medicine storage chamber is connected to the medicine storage port, and the conveying channel is connected to the medicine outlet. A spiral conveying blade is rotatably installed along the conveying channel direction. The spiral conveying blades are driven to rotate by a rotating power device. Several rotating disks are evenly installed at the medicine outlet on the medicine storage bin. Several medicine dispensing rods are distributed circumferentially on the rotating disks. A slowing conveying structure is provided between the rotating disks and the spiral drive blades to slow down the conveying of Chinese herbal medicines. The medicine dispensing rod is divided into a connecting rod part and a medicine dispensing rod part. The connecting rod part is installed on the rotating disk. The medicine dispensing rod part is inclined outward and connected to the connecting rod part. The medicine dispensing rod part is close to the bottom of the medicine outlet. The rotating disks are driven to rotate by the medicine dispensing power device.

[0006] As a preferred embodiment, the deceleration conveying structure includes an inclined pressure plate connected downstream of the conveying channel to reduce the capacity of the conveying channel, and the inclined baffle is provided with an elastic pressure plate that extends in the same direction as the inclined baffle to release pressure.

[0007] As a preferred embodiment, a dispensing sleeve is fitted onto the dispensing rod, the dispensing sleeve including a fitting part fitted onto the dispensing rod and an agitating part for dispensing the medicine, the agitating part extending horizontally outward from the center of the rotating disk, and the dispensing power device including a dispensing motor, the dispensing motor being mounted on a medicine storage chamber located above the dispensing port.

[0008] As a preferred embodiment, the dispensing motor is mounted on the dispensing bracket, and the dispensing port of the medicine storage chamber is provided with a mounting slot for mounting the dispensing bracket. The output shaft of the dispensing motor passes through the dispensing bracket and is connected to the rotating disk. The dispensing bracket can be adjusted and moved along the output channel direction at the dispensing port through the mounting slot.

[0009] As a preferred embodiment, the elastic pressure plate has several strip-shaped notches along the conveying channel direction, and the elastic pressure plate forms several elastic pressure strips through the several strip-shaped notches.

[0010] As a preferred embodiment, the drug storage compartment is connected to the drug storage chamber and the conveying channel by a guide cone surface, and the drug storage compartment at the conveying channel is a V-shaped inclined surface that cooperates with the spiral conveying blades for guidance.

[0011] As a preferred embodiment, the device includes a frame and the aforementioned herbal medicine dispensing device, wherein the array of herbal medicine dispensing devices is mounted on the frame; the weighing mounting frame of the herbal medicine dispensing device is fixed on the frame; a guide dispensing bin is fixedly installed on the frame; the guide dispensing bin is provided with dispensing ports that correspond one-to-one with each dispensing port; and a dispensing box is provided on the frame to collect the herbal medicines falling from the guide dispensing bin.

[0012] After adopting the above technical solution, the effect of this utility model is as follows: The herbal medicine dispensing device includes a medicine storage chamber. One side of the medicine storage chamber has a medicine storage port, and the other side has a medicine outlet. The medicine storage chamber is mounted on a weighing frame via a weighing device. The medicine storage chamber contains a medicine storage cavity for placing herbal medicines and a conveying channel located below the medicine storage cavity. The medicine storage cavity is connected to the medicine storage port, and the conveying channel is connected to the medicine outlet. A spiral conveying blade is rotatably installed along the conveying channel direction within the conveying channel. The spiral conveying blade is driven to rotate by a rotational power device. Several rotating disks are evenly rotatably installed on the medicine storage chamber at the medicine outlet. Several medicine dispensing rods are circumferentially distributed on the rotating disks. A slowing conveying structure is provided between the rotating disks and the spiral drive blades to slow down the conveying of herbal medicines. The medicine dispensing rod is divided into a connecting rod part and a medicine dispensing rod part. The connecting rod part is mounted on the rotating disk, and the medicine dispensing rod part is inclined outwards. Connected to the connecting rod, the dispensing rod is located near the bottom of the dispensing port. The rotating disk is driven to rotate by the dispensing power device. First, bulk Chinese herbal medicines are placed into the storage port. Then, the scattered Chinese herbal medicines fall from the storage chamber into the conveying channel. The rotating power device drives the spiral conveying blades to rotate. Because the contact area between the spiral conveying blades and the Chinese herbal medicines is larger, the spiral conveying blades continuously squeeze and convey the Chinese herbal medicines, allowing them to be continuously conveyed downstream. Then, the Chinese herbal medicines are slowly conveyed through the slowing conveying structure, where they gradually accumulate. The dispensing power device then drives the rotating disk to rotate, thereby driving the dispensing rod to rotate. The dispensing rod agitates the accumulated Chinese herbal medicines and effectively carries them out of the dispensing port. As the Chinese herbal medicines are carried out of the dispensing port, the weighing device can detect the weight change in real time, thus determining the weight of the dispensing Chinese herbal medicines. This dispensing machine can ensure reliable delivery of Chinese herbal medicines during dispensing, thereby controlling the dispensing weight and improving accuracy.

[0013] Furthermore, the conveying slowdown structure includes an inclined pressure plate connected downstream of the conveying channel to reduce the capacity of the conveying channel. The inclined pressure plate is provided with an elastic pressure plate that extends in the same direction as the inclined pressure plate to release pressure. When the Chinese herbal medicine is squeezed and conveyed to the inclined pressure plate, the conveying space will be squeezed to slow down the conveying. However, as the Chinese herbal medicine is continuously conveyed, the accumulated Chinese herbal medicine will increase, resulting in high pressure. The elastic pressure plate can appropriately expand the conveying space to reduce the conveying pressure and ensure the stability of the Chinese herbal medicine conveying.

[0014] Furthermore, since a dispensing sleeve is fitted onto the dispensing rod, the dispensing sleeve includes a fitting part fitted onto the dispensing rod and an agitating part for stirring and dispensing the medicine. The agitating part extends horizontally outward from the center of the rotating disk. The dispensing power device includes a dispensing motor, which is installed on the medicine storage chamber located above the dispensing port. Fitting the dispensing sleeve onto the dispensing rod facilitates disassembly and replacement, and the agitating part on the dispensing sleeve can contact the bottom of the dispensing port as much as possible. In this way, when the dispensing rod rotates, it will stir and dispense the Chinese herbal medicine. Since the area where the dispensing rod rotates is fixed, for ease of description, it is called the dispensing area. After the Chinese herbal medicine is dispensed, there will be some empty space in the dispensing area. At this time, since the Chinese herbal medicine is more accumulated in the slowing area, while the upstream spiral conveyor blades continue to convey, the accumulated Chinese herbal medicine will be smoothly and reliably replenished to the dispensing area where the dispensing rod rotates. This ensures that the Chinese herbal medicine is continuously and reliably dispensed.

[0015] Furthermore, since the dispensing motor is mounted on the dispensing bracket, and the dispensing port of the medicine storage chamber is provided with a mounting slot for mounting the dispensing bracket, the output shaft of the dispensing motor passes through the dispensing bracket and connects to the rotating disk. The dispensing bracket can be adjusted and moved along the output channel direction at the dispensing port through the mounting slot. In this way, the position of the dispensing rod at the dispensing port can be adjusted by moving the dispensing bracket along the mounting slot, which is convenient for installation and can also change the dispensing position for different Chinese herbal medicines, thus improving flexibility.

[0016] Furthermore, since the elastic pressure plate has several strip-shaped notches along the conveying channel, the elastic pressure plate forms several elastic pressure strips through these notches. During the conveying of Chinese herbal medicine, it may get stuck at the inclined pressure plate and be irregular in shape. Therefore, when moving towards the elastic pressure strip, the elastic pressure strip can effectively adapt to the shape corresponding to the output of Chinese herbal medicine, improve the buffering effect, and enhance practicality.

[0017] Furthermore, since the medicine storage chamber is connected to the medicine storage cavity and the conveying channel by a guide cone surface, and the medicine storage chamber at the conveying channel is a V-shaped inclined surface that cooperates with the spiral conveying blades for guidance, it facilitates the accurate falling of Chinese herbal medicines and enables the Chinese herbal medicines to be effectively gathered in the conveying channel through the V-shaped inclined surface for conveying by the spiral conveying blades.

[0018] Furthermore, since the system includes a frame and the aforementioned herbal medicine dispensing device, the array of herbal medicine dispensing devices is mounted on the frame; the weighing mounting frame of the herbal medicine dispensing device is fixed on the frame; a guide dispensing bin is fixedly installed on the frame; the guide dispensing bin has dispensing ports that correspond one-to-one with each dispensing port; and a dispensing box is provided on the frame to collect the herbal medicine falling from the guide dispensing bin; the guide dispensing bin facilitates the collection of medicines from several storage bins, which can then be collected by the dispensing box, effectively completing the dispensing process.

[0027] The present invention will be further described in detail below through specific embodiments.

[0028] like Figures 1 to 4As shown, a traditional Chinese medicine dispensing device includes a medicine storage chamber 1. A medicine storage port 2 is located on one side of the medicine storage chamber 1, and a medicine outlet 3 is located on the other side. The medicine storage chamber 1 is mounted on a weighing frame 4 via a weighing device. The medicine storage chamber 1 contains a medicine storage chamber 5 for storing traditional Chinese medicine and a conveying channel 6 located below the medicine storage chamber 5. The medicine storage chamber 5 is connected to the medicine storage port 2, and the conveying channel 6 is connected to the medicine outlet 3. A spiral conveying blade 7 is rotatably installed along the direction of the conveying channel 6. The spiral conveying blade 7 rotates... Driven by a power device, the medicine storage chamber 1 has several rotating disks 8 evenly installed at the medicine outlet 3. Several medicine dispensing rods 9 are distributed circumferentially on the rotating disks 8. A slowing conveying structure is provided between the rotating disks 8 and the spiral drive blades to slow down the conveying of Chinese herbal medicines. The medicine dispensing rods 9 are divided into connecting rod parts 10 and dispensing rod parts 11. The connecting rod parts 10 are installed on the rotating disks 8, and the dispensing rod parts 11 are inclined outward and connected to the connecting rod parts 10. The dispensing rod parts 11 are close to the bottom of the medicine outlet 3. The rotating disks 8 are driven to rotate by the medicine dispensing power device.

[0029] The rotational power device is a rotary conveyor motor 12, which is fixedly installed on the medicine storage bin 1 in the opposite direction of the conveying channel 6. The output shaft of the rotary conveyor motor 12 passes through the medicine storage bin 1 and is fixedly connected to the spiral drive blades to support rotation, thereby driving the conveying of Chinese herbal medicines. The spiral drive blades have a large contact area with the Chinese herbal medicines, which makes the conveying stable and reduces the impact of idling.

[0030] In this embodiment, the deceleration structure includes an inclined pressure plate 13 connected downstream of the conveying channel 6 to reduce the capacity of the conveying channel 6. The inclined pressure plate is provided with an elastic pressure plate that extends in the same direction as the inclined pressure plate to release pressure. When the Chinese herbal medicine is squeezed and conveyed to the inclined pressure plate 13, the conveying space will be squeezed to slow down the conveying. However, as the Chinese herbal medicine is continuously conveyed, the accumulated Chinese herbal medicine will increase, resulting in high pressure. The elastic pressure plate can appropriately expand the conveying space to reduce the conveying pressure and ensure the stability of the Chinese herbal medicine conveying.

[0031] like Figure 3As shown, a dispensing sleeve 14 is fitted onto the dispensing rod 11. The dispensing sleeve 14 includes a fitting part 15 fitted onto the dispensing rod 11 and a stirring part 16 for stirring and dispensing the medicine. The stirring part 16 extends horizontally outward from the center of the rotating disk 8. The dispensing power device includes a dispensing motor 17, which is installed on the medicine storage chamber 1 located above the dispensing port 3. Four dispensing rods 9 are circumferentially mounted on the rotating disk 8, and each dispensing rod 11 is fitted with a dispensing sleeve 14. The stirring part 16 on the dispensing sleeve 14 is in contact with the bottom of the dispensing port 3 as much as possible. Then, the rotation can effectively drive the conveyed Chinese herbal medicine to be discharged, further improving the stability of the dispensing, ensuring accurate and reliable delivery, and facilitating disassembly to replace dispensing sleeves 14 of different shapes, thereby improving flexibility.

[0032] like Figure 1 As shown, the dispensing motor 17 is mounted on the dispensing bracket 27. The dispensing port 3 of the medicine storage chamber 1 is provided with a mounting slot 18 for mounting the dispensing bracket 27. The output shaft of the dispensing motor 17 passes through the dispensing bracket 27 and is connected to the rotating disk 8. The dispensing bracket 27 can be adjusted and moved along the output channel direction at the dispensing port 3 through the mounting slot 18. By moving the dispensing bracket 27 along the mounting slot 18, the position of the dispensing rod 9 at the dispensing port 3 can be adjusted, which facilitates installation and allows for different dispensing positions to be changed for different Chinese herbal medicines, thus improving flexibility.

[0033] like Figure 2 and Figure 3 As shown, the elastic pressure plate has several strip-shaped notches along the direction of the conveying channel 6, and the elastic pressure plate forms several elastic pressure strips 19 through the strip-shaped notches; the entire elastic pressure plate is divided into several elastic pressure strips 19, which not only can be pressed down as a whole, but when the pressure at a certain elastic pressure strip 19 is too high, the elastic pressure strip 19 can be adjusted upward to release the corresponding pressure. During the transportation of Chinese herbal medicine, the shape of the Chinese herbal medicine is irregular. Therefore, when it moves towards the elastic pressure strip 19, the elastic pressure strip 19 can effectively adapt to the corresponding shape when the Chinese herbal medicine is output, improve the buffering effect, and improve practicality.

[0034] In this embodiment, the medicine storage chamber 1 is located between the medicine storage chamber 5 and the conveying channel 6 via a guide cone surface 20. The medicine storage chamber 1 at the conveying channel 6 is a V-shaped inclined surface 21 that cooperates with the spiral conveying blade 7 for guidance. The guide cone surface 20 facilitates the accurate falling of Chinese herbal medicines and enables the Chinese herbal medicines to be effectively gathered in the conveying channel 6 through the V-shaped inclined surface 21 for conveying by the spiral conveying blade 7.

[0035] This utility model also provides an automatic Chinese herbal medicine dispensing machine, such as Figure 5 and Figure 6As shown, the device includes a frame 22 and the aforementioned herbal medicine dispensing device. The array of herbal medicine dispensing devices is mounted on the frame 22. The weighing mounting frame 4 of the herbal medicine dispensing device is fixed on the frame 22. A guide medicine dispensing bin 23 is fixedly installed on the frame 22. The guide medicine dispensing bin 23 is provided with a medicine dispensing port 25 that corresponds to each medicine outlet 3. The frame 22 is provided with a medicine dispensing box 24 for collecting the herbal medicine falling from the guide medicine dispensing bin 3. The frame 22 is provided with four rows and four columns of medicine storage bins 1, which allows for the dispensing of as much medicine as possible within a single frame 22. The structure is compact and the usage effect is improved. The herbal medicine output from the medicine outlet 3 will fall into the guide medicine dispensing bin 23. The guide medicine dispensing bin 23 is provided with a medicine dispensing port 25 and a medicine discharge port 26 corresponding to each medicine storage bin 1. The medicine discharge port 26 corresponds to the medicine dispensing box 24, which can effectively collect the medicine.

[0036] The working principle of this embodiment is as follows: First, the Chinese herbal medicine is manually placed into the storage chamber 1 through the medicine storage port 2. Then, the conveyor motor 12 drives the spiral drive blade to rotate, the medicine dispensing motor 17 drives the rotating disk 8 to rotate, which in turn drives the medicine dispensing rod 9 to rotate. The stirring part 16 on the medicine dispensing sleeve 14 can stir and output the Chinese herbal medicine. The Chinese herbal medicine is output from the medicine dispensing port 3 and falls into the guide medicine dispensing chamber 23, and finally enters the medicine dispensing box 24.
