Description
Technical Field
[0001] The utility model relates to the technical field of automatic dispensing of traditional Chinese medicines, in particular to an anti-airflow uniform dispensing machine, which is particularly suitable for clumping herbs or large pieces of medicine. Background Art
[0002] Chinese medicine refers to drugs used for prevention, diagnosis, treatment or regulation of human functions under the guidance of traditional Chinese medicine theory, including Chinese medicine and Chinese patent medicine. Among them, there are many kinds of Chinese medicine. The earliest "Shennong Bencao Jing" alone records as many as 365 Chinese medicines, and most of them are still in use today. At present, according to surveys and statistics by domestic and foreign scholars, there are about 500 Chinese medicines commonly used in clinical practice, of which about 250 are the most commonly used.
[0003] Among traditional Chinese medicines, some are herbal medicines and some are large tablet-shaped medicines. In the development of automated equipment for dispensing traditional Chinese medicines, the inventors found that when dispensing herbal medicines or large tablet-shaped medicines, when such traditional Chinese medicines are transported from a silo with a feed port to the next process, since the herbal medicines themselves are in piles and clumps, they will accumulate in clumps at the feed port of the silo, resulting in empty clumps under the herbal medicines, so that the conveying mechanism cannot convey the herbal medicines, causing the herbal medicines to become empty. Since the large tablets of medicines enter the silo all at once, the large tablets of medicines at the bottom may form bridges, and the bottom of the large tablets of medicines will also become hollow, which will also cause the large tablets of medicines to become empty.
[0004] In view of this, how to solve the problem that the existing automatic dispensing equipment will empty the medicine when dispensing herbal medicines and large-scale medicines has become a topic to be studied and solved by the present utility model. Utility Model Content
[0005] The utility model aims to provide an anti-empty uniform medicine dispensing machine to solve the problem that the existing automatic medicine dispensing equipment may empty the medicine when dispensing herb medicines and large-piece medicines.
[0006] To achieve the above purpose, the utility model proposes an anti-air-release uniform medicine dispensing machine for automatic dispensing of traditional Chinese medicine. The innovation point is that the anti-air-release uniform medicine dispensing machine includes a frame and a silo, a conveying mechanism, and a medicine dispensing mechanism installed on the frame;
[0007] The silo is a container for containing Chinese medicine, and has a medicine adding port and a medicine dropping port, wherein the medicine adding port is arranged on the side or top of the silo, and the medicine dropping port is arranged toward the conveying mechanism;
[0008] The conveying mechanism includes a conveying belt and a conveying driving unit for driving the conveying belt. The conveying belt is arranged on the frame in a slope shape. The conveying belt has a medicine loading end and a medicine discharging end. The height of the medicine loading end is lower than that of the medicine discharging end. The opening of the medicine discharging end is connected to the medicine dispensing mechanism.
[0009] The medicine dispensing mechanism is a mechanism for conveying medicines, and is arranged on one side of the medicine dispensing end of the conveyor belt.
[0010] The relevant contents of this utility model are explained as follows:
[0011] 1. In the above technical scheme of the utility model, the Chinese medicine is poured into the silo from the medicine adding port, and then falls onto the conveyor belt from the medicine dropping port of the silo. The conveying drive unit drives the conveyor belt to run, and the conveyor belt transports the Chinese medicine obliquely upward. The Chinese medicine will be scattered and separated during the upward conveyor belt, and the Chinese medicine will enter the medicine dispensing mechanism from the medicine outlet end of the conveyor belt, so as to prevent the Chinese medicine from being emptied and dispensing the medicine evenly and automatically. The main purpose of preventing the medicine from being emptied in the silo is to prevent the medicine in the silo from being emptied. If the medicine dispensing mechanism is directly connected to the silo, then no matter it is a screw, a vibrating disk, or a conveyor belt, After the Chinese medicines in contact with them are transported away, cavities will be formed on the screw, conveyor belt or vibration plate due to the clumping of herbs or the overlapping of large pieces of medicine. Either a mechanical structure is added to stir and destroy the cavity before dispensing the medicine, or the clumped or overlapping pieces need to be manually dispersed. In order to avoid the formation of cavities, the anti-cavity uniform medicine dispensing machine is designed, which allows the Chinese medicines to be evenly transported out and allows the conveyor belt to move the bottom of the material obliquely upward during the oblique upward movement to avoid cavities. There is no need for manual intervention, thus ensuring the continuity and accuracy of automatic medicine dispensing.
[0012] 2. In the above technical solution, a blocking part for separating the Chinese medicine to fit the conveyor belt is provided on the moving path of the Chinese medicine from the medicine feeding end to the medicine discharging end. The blocking part further disperses and separates the clumped herbs or accumulated sheet medicines after being blocked by the blocking part, allowing the Chinese medicine to pass under the blocking part and then enter the medicine dispensing mechanism from the medicine discharging end.
[0013] 3. In the above technical solution, the blocking part and the conveyor belt cooperate with each other through a gap adjustment mechanism, so that the gap between the blocking part and the conveyor belt is adjustable. In this way, the gap between the blocking part and the conveyor belt can be adjusted according to the different specifications and sizes of the herbal clumps or piles of tablet medicines, so that the specific herbal clumps or piles of tablet medicines can be better used by the device to prevent air from spreading and evenly distribute the medicines.
[0014] 4. In the above technical solution, the blocking part is a scraper arranged near the medicine outlet end, and a gap for the selective passage of medicine is formed between the scraper and the conveyor belt, so as to block the clumped herbs or piled tablet medicines. The clumped herbs and piled medicines are flattened under the conveying force of the conveyor belt and the reaction force of the scraper, so that the height of the medicine entering the hopper is limited, thereby further avoiding accumulation or overlapping to form a bottom cavity and avoiding hollowing.
[0015] 5. In the above technical solution, the blocking part is a roller arranged on the moving path of the Chinese medicine, and the rolling direction of the roller is opposite to the conveying direction of the conveyor belt. By arranging rollers with opposite rolling directions, the rollers can roll and push the clumped herbs and piled medicines from top to bottom, so that the clumped herbs can be broken up or tableted, and the piled large pieces of medicines can be pushed apart, thereby reducing the height and quantity of the stack.
[0016] 6. In the above technical solution, the roller action surface of the roller is a rough surface or a surface with protrusions or teeth, so as to better increase the effect of shifting materials in the opposite direction.
[0017] 7. In the above technical solution, the conveyor belt is provided with a plurality of partitions at intervals. The plurality of partitions divide the conveyor belt into compartments, and the herbs or tablet medicines can be lifted to the medicine outlet by the cooperation of the partitions and the conveyor belt, and the oblique upward transportation is more convenient.
[0018] 8. In the above technical solution, the gap between the silo and the conveyor belt is provided with a soft elastic material, which is fixed on the silo and can be fixed on the bottom of the silo. The spacer strip on the belt can pass through the gap between the medicine storage hopper and the bottom edge of the conveyor belt without being stuck, and the soft elastic material is in frictional contact with the conveyor belt, so that the material is not easy to enter between the medicine storage hopper and the belt and cause the conveyor belt to be stuck.
[0019] 9. In the above technical solution, a hopper is provided between the conveying mechanism and the medicine dispensing mechanism. The hopper is provided on the medicine dispensing end side of the conveyor belt. The hopper has a feed port open toward the medicine dispensing end and a discharge port open toward the medicine dispensing mechanism. The hopper can be used for transition, so that the Chinese medicine can be transferred from the medicine dispensing end of the conveyor belt through the hopper and then to the medicine dispensing mechanism, thereby avoiding scattering of the Chinese medicine.
[0020] 10. In the above technical solution, the medicine dispensing mechanism is provided with a cutter for chopping the medicine into pieces. The cutter chop the medicine into pieces to dispense the medicine more quickly and accurately.
[0021] 11. In the above technical solution, the medicine dispensing mechanism is a screw conveying mechanism, a belt conveying mechanism or a vibration plate conveying mechanism, so as to quickly dispense the loosened sticky Chinese medicine.

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0041] As attached Figure 1 As shown, the utility model proposes an anti-air-release uniform medicine dispensing machine for automatic dispensing of traditional Chinese medicine, and its innovation lies in: the anti-air-release uniform medicine dispensing machine includes a frame 1 and a silo 6, a conveying mechanism 2, and a medicine dispensing mechanism 4 installed on the frame 1; the silo 6 is a container for containing traditional Chinese medicine, and the silo 6 has a medicine adding port 61 and a medicine dropping port, the medicine adding port 61 is arranged on the side or top of the silo 6, and the medicine dropping port is arranged toward the conveying mechanism 2; the conveying mechanism 2 includes a conveyor belt 21 and a conveying drive unit 22 for driving the conveyor belt 21 to transmit, the conveyor belt 21 is arranged on the frame 1 in a slope shape, and the conveyor belt 21 has a medicine loading end 211 and a medicine discharging end 212, the height of the medicine loading end 211 is lower than the medicine discharging end 212, and the open end of the medicine discharging end 212 is connected to the medicine dispensing mechanism 4; the medicine dispensing mechanism 4 is a mechanism for conveying the medicine out, and the medicine dispensing mechanism 4 is arranged on the side of the medicine discharging end 212 of the conveyor belt 21.
[0042] Through the implementation of the above-mentioned embodiment of the utility model, the Chinese medicine is poured into the silo 6 from the medicine adding port 61, and then falls onto the conveyor belt 21 from the medicine dropping port of the silo 6. The conveying drive unit 22 drives the conveyor belt 21 to run, and the conveyor belt 21 transports the Chinese medicine obliquely upward. The Chinese medicine will be scattered and separated during the upward conveyor belt 21, so that the Chinese medicine enters the medicine dispensing mechanism 4 from the medicine outlet end 212 of the conveyor belt 21, so as to prevent the Chinese medicine from being emptied and dispensing the medicine evenly and automatically. The main purpose of preventing the medicine from being emptied is to prevent the medicine in the silo 6 from being emptied. Because if the medicine dispensing mechanism 4 is directly connected to the silo 6, then no matter it is a screw, a vibrator, or a pump, the medicine will not be discharged. After the moving plate or conveyor belt 21 conveys the Chinese medicine that has come into contact with them, cavities will be formed on the screw or conveyor belt 21 or the vibrating plate due to the clumping of herbs or the overlapping of large pieces of medicine. Either a mechanical structure is added to stir and destroy the cavity before dispensing the medicine, or the clumped or overlapping pieces are manually dispersed. In order to avoid the formation of cavities, the anti-cavity uniform medicine dispensing machine is designed to allow the Chinese medicine to be evenly transported out, and to allow the conveyor belt 21 to move the bottom of the material obliquely upward during the oblique upward movement to avoid cavities. There is no need for manual intervention, thereby ensuring the continuity and accuracy of automatic medicine dispensing.

In this way, the gap between the blocking part 5 and the conveyor belt 21 can be adjusted according to the clumped herbs or piled tablet medicines of different specifications and sizes, so that specific clumped herbs or piled tablet medicines can be better used by the device to prevent air from being discharged evenly.
[0044] In another embodiment of the utility model, the blocking portion 5 is a scraper 51 arranged near the medicine outlet end 212, and a gap for the selective passage of medicines is formed between the scraper 51 and the conveyor belt 21, so as to block the clumped herbs or piles of tablet medicines. The clumped herbs and piles of medicines are flattened under the conveying force of the conveyor belt 21 and the reaction force of the scraper 51, so that the height of the medicines entering the hopper 3 is limited, thereby further avoiding accumulation or overlapping to form a bottom cavity and avoiding hollowing.
[0045] In another embodiment of the utility model, the blocking part 5 is a roller arranged on the moving path of the traditional Chinese medicine, and the rolling direction of the roller is opposite to the conveying direction of the conveyor belt 21. By arranging rollers with opposite rolling directions, the rollers can roll and push the clumped herbs and piled medicines from top to bottom, so that the clumped herbs can be broken up or tableted, and the piled large pieces of medicines can be pushed apart, thereby reducing the height and quantity of the stack.

[0048] Specifically, the gap between the silo 6 and the conveyor belt 21 has a soft elastic material, which is fixed on the silo 6 and can be fixed on the bottom of the silo 6. The spacer 213 on the belt can pass through the gap between the medicine storage hopper and the bottom edge of the conveyor belt 21 without being stuck, and the soft elastic material is in frictional contact with the conveyor belt 21, so that the material is not easy to enter between the medicine storage hopper and the belt and cause the conveyor belt 21 to be stuck.
[0049] In another embodiment of the utility model, a hopper 3 is provided between the conveying mechanism 2 and the medicine dispensing mechanism 4. The hopper 3 is provided on the side of the medicine dispensing end 212 of the conveyor belt 21.
