The mounting groove 511 and the threaded through hole 512 on the first baffle plate 51 are aligned with the first avoidance groove 522 on the connecting plate 52 and the second avoidance groove 533 on the second baffle plate 53, and the gap between the first rib 513 on the first baffle plate 51 and the two second ribs 532 on the second baffle plate 53 is aligned; one end of the feed spring 50 is clamped on the connecting plate 52, and the first rib 513 on the first baffle plate 51 and the second rib 532 on the second baffle plate 53 clamp the feed spring 6 on the connecting plate 52, and the end of the feed spring 50 passes through the mounting groove 511 and extends into the first avoidance groove 522 on the connecting plate 52, and then a bolt is threadedly connected in the threaded through hole 512 on one side of the end of the feed spring 50, and the bolt can abut against the end of the feed spring 50 to fix the feed spring 50 on the spring mounting plate 5. In this embodiment, the first baffle plate 51 , the connecting plate 52 and the second baffle plate 53 are all hollowed out to reduce the weight of the spring mounting plate 5 , thereby reducing the working load of the worm reduction motor 44 .

[0032] The working principle of the herbal medicine dispensing device 3 of the above structure is as follows: the weight of the herbs to be weighed is set in advance in the central control mechanism, and the herbs fall downward from the first discharge port of the first barrel 31 into the discharge cavity 42 in the discharge hopper 4, and are received by the feeding spring 50 in the discharge cavity 42. The central control mechanism controls the worm reduction motor 44 to drive the feeding spring 50 to rotate, and the rotation of the feeding spring 50 drives the herbs to move toward the first weighing hopper 14, and finally the herbs fall into the first weighing hopper 14. When the herbs dropped into the first weighing hopper 14 reach the specified weight, the first weighing hopper 14 sends a signal to the central control mechanism, and the central control mechanism controls the worm reduction motor 44 to stop rotating. The weight of the herbs in the first weighing hopper 14 is the required weight, and then the first weighing hopper 14 opens to drop the herbs into the first collecting hopper 11. After passing through the first collecting hopper 11, the herbs enter the packaging station on the packaging machine 8, and the packaging machine 8 can package the herbs at the packaging station.

[0033] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, in this embodiment, the granular Chinese medicine dispensing device 2 comprises: a second barrel 21 arranged on the frame 1, a second feed port and a second discharge port are provided on the second barrel 21, a second door sealing plate 22 is provided on the second feed port, the second door sealing plate 22 is hinged to the side wall of the second barrel 21 through a hinge, a second barcode scanning lock 23 capable of locking the second door sealing plate 22 is provided on the second barrel 21, and an identification code 34 corresponding to the second barcode scanning lock 23 is provided on the second door sealing plate 22, and the identification code 34 includes information such as the name of the medicinal material. The bulk medicinal material packaging on the market is now affixed with an identification code of the corresponding medicinal material information. After using a barcode scanning gun to scan the identification code 34 on the second door sealing plate 22, the barcode scanning gun is used to scan the identification code on the corresponding medicinal material packaging. Only when the names of the medicinal materials obtained by scanning twice in the barcode scanning gun are consistent, the second barcode scanning lock 23 will be unlocked, and the medical staff can open the second door sealing plate 22, which greatly reduces the probability of adding the wrong medicinal material.

[0034] A second dustproof plate 24 is provided on the inner side wall of the second door sealing plate 22, and the lower end of the second dustproof plate 24 extends downward to cover the hinge connected to the second door sealing plate 22. When adding medicinal materials, the second dustproof plate 24 can prevent the medicinal materials from getting stuck on the hinge, thereby protecting the hinge. A baffle plate 25 is slidably provided on the second barrel 21, and the connection structure between the baffle plate 25 and the second barrel 21 is as follows: three connecting screws 251 are arranged at intervals on the lower side wall of the second barrel 21, and three sliding grooves are arranged at intervals on the baffle plate 25, and the three sliding grooves are respectively arranged on the three connecting screws 251, and a nut 252 is threadedly connected to each of the three connecting screws 251, and the baffle plate 25 can slide up and down by loosening the three nuts 252, and the baffle plate 25 can slide downward to cover the second discharge port on the second barrel 21, and the baffle plate 25 can be fixed by tightening the three nuts 252. The baffle plate 25 can slide up and down to control the size of the second discharge port of the second barrel 21, thereby controlling the discharge amount of the granular medicinal material. A vibrator 6 is arranged on the frame 1 located below the second barrel 21. The vibrator 6 in this embodiment can be a TYF-35 vibrator produced by Foshan Teyafei Technology Co., Ltd. Four vibration-damping feet 61 are arranged at the bottom of the vibrator 6, and the vibrator 6 is placed on the frame 1 through the vibration-damping feet 61. Two positioning blocks 15 are arranged on the frame 1, and two semicircular grooves are respectively opened on each positioning block 15. When the vibrator 6 is placed on the frame 1, the two positioning blocks 15 are respectively placed on both sides of the vibrator 6, and are fixedly connected to the frame 1 by bolts. The two semicircular grooves on each positioning block 15 are respectively embedded in the two vibration-damping feet 61 located on the same side of the vibrator 6, thereby fixing the vibrator 6 on the frame 1. A feeding plate 7 with a groove shape is tiltedly arranged on the vibrator 6, the receiving portion of the feeding plate 7 is aligned with the second discharge port of the second barrel 21, the discharge portion of the feeding plate 7 is lower than the receiving portion of the feeding plate 7, and a second weighing hopper 16 is arranged on the frame 1 located on one side of the discharge portion of the feeding plate 7, the discharge end of the second weighing hopper 16 extends into the second collecting hopper 12, and the discharge portion of the feeding plate 7 extends into the second weighing hopper 16. The second weighing hopper 16 is electrically connected to the vibrator 6 through the central control mechanism.

[0035] like Fig.10As shown, in the present embodiment, the discharge portion of the feed plate 7 is wider than the receiving portion of the feed plate 7, and a plurality of dovetail guide plates 71 are arranged at intervals on the feed plate 7, the closed end of the dovetail guide plate 71 faces the receiving portion of the feed plate 7 and is downwardly attached to the feed plate 7, and the open end of the dovetail guide plate 71 faces the discharge portion of the feed plate 7, is arched upward, and is higher than the closed end of the dovetail guide plate 71. When the feeding plate 7 vibrates, the granular medicinal materials move at a uniform speed from the receiving part to the discharging part. When the granular medicinal materials pass through the dovetail guide plate 71, the granular medicinal materials piled together will be scattered on the feeding plate 7 under the guiding effect of the dovetail guide plate 71. The discharging part of the feeding plate 7 is wider than the receiving part, so when the granular medicinal materials reach the feeding part, they are evenly spread, which can ensure that the granular medicinal materials can fall into the second weighing hopper 16 at a uniform speed and in a uniform amount, thereby improving the weight accuracy of the granular medicinal materials falling into the second weighing hopper 16. In the process of using the dovetail guide plate 71, multiple dovetail guide plates 71 can be placed at intervals according to the conveying length of the feeding plate 7, so as to achieve a better conveying effect.

[0036] During the research and development process, the researchers found that the granular medicinal materials located near the groove wall of the discharge part of the feed plate 7 have been rotating in place and cannot fall into the second weighing hopper 16. Later, through experiments, they found that a resonance reaction occurred between the granular medicinal materials located at the discharge part and the side wall, which prevented the granular medicinal materials from falling. Therefore, an arc chamfer 72 is provided on the groove wall of the discharge part of the feed plate 7, so that a vibration-damping notch 73 is left between the groove wall and the discharge part. The vibration-damping notch 73 can eliminate the resonance reaction between the granular medicinal materials and the groove wall of the discharge part, so that the granular medicinal materials located near the groove wall of the discharge part of the feed plate 7 can also fall smoothly into the second weighing hopper 16.

[0037] The working principle of the granular Chinese medicine dispensing device 2 of the above structure is as follows: the weight of the medicinal materials to be weighed is set in advance in the central control mechanism, and then the baffle plate 25 on the first barrel 21 is slid upward and fixed, and the granular medicinal materials fall downward from the discharge port on the first barrel 21 and accumulate on the receiving part of the feeding plate 7. The central control mechanism is started to control the vibrator 6 to drive the feeding plate 7 to vibrate at a uniform speed. Under the action of vibration, the granular medicinal materials move at a uniform speed on the feeding plate 7 to the discharge part. During the movement, the granular medicinal materials are scattered under the guiding action of the dovetail guide plate 71, and the granular medicinal materials are in a scattered state when they reach the discharge part. Then, under the action of vibration, the granular medicinal materials fall into the second weighing hopper 16 at a uniform speed and in a uniform amount. When the granular medicinal materials falling into the second weighing hopper 16 reach the specified weight, the second weighing hopper 16 sends a signal to the central control mechanism, and the central control mechanism controls the vibrator 6 to stop vibrating. The weight of the medicinal materials in the second weighing hopper 6 is the required weight, and then the second weighing hopper 16 is opened to drop the granular medicinal materials into the second collecting hopper 12. After passing through the second collecting hopper 12, the granular medicinal materials enter the packaging station on the packaging machine 8, and the packaging machine 8 can package the granular medicinal materials located at the packaging station.

[0038] The invention has the advantages of not only being able to automatically dispense different types of Chinese herbal medicines, but also greatly improving the weight accuracy and work efficiency of dispensed medicines.
