[0003] Most modern automatic dispensing machines use an automatic dispensing device that stores medicines by type in inclined spring-loaded troughs, with an electric push rod or screw propeller at the rear. Once triggered, the medicine is pushed onto a conveyor belt and then transported to the dispensing port via a chute.

[0004] Because most current automatic dispensing machines store medicines by type in inclined troughs, medicines often get stuck and cannot slide out as instructed. Furthermore, staff cannot be notified in time when medicine boxes jam, affecting the normal operation of the system. In addition, there are problems with slow dispensing speed and low efficiency. Therefore, an automatic dispensing device for automatic dispensing machines is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 5 This utility model provides an embodiment of an automatic medicine dispensing device for an automatic medicine dispensing machine, comprising a housing 1 and a base 21. Multiple straight rods 29 are fixedly connected to the inner side of the housing 1, and multiple medicine troughs 2 are rotatably connected to the outer side of the straight rods 29. The straight rods 29 can fix the medicine troughs 2 in the housing 1, and allow the medicine troughs 2 to move at small angles. A motor 23 is fixedly connected to the rear of the base 21. The motor 23 has sufficient power, is small in size, and is energy-efficient. A crankshaft 22 is fixedly connected to the front output end of the motor 23. A slider 19 is rotatably connected to the middle of the crankshaft 22, and a top block 20 is rotatably connected to the top of the slider 19. The base 21 is topped with... A telescopic rod 18 is fixedly connected to the top of the top block 20. The top of the telescopic rod 18 is fixedly connected to the bottom of the top block 20. A spring 27 is fixedly connected to the top of the base 21. The top of the spring 27 is fixedly connected to the bottom of the top block 20. By rotating the crankshaft 22, the slider 19 can be driven to continuously strike the top block 20. The vibration effect can be achieved by cooperating with the springs 27 in the telescopic rods 18 on both sides. A conveyor belt 4 is installed at the bottom of the outer shell 1. The required medicine is transported to the next position by the conveyor belt 4. A lifting component is installed on the outside of the outer shell 1. A feeding component is installed on the outside of the lifting component.

[0033] Reference Figure 4 An electric push rod 26 is fixedly connected to the bottom of the medicine tank 2. A rack 25 is fixedly connected to the front output end of the electric push rod 26. A gear 24 is rotatably connected to the bottom of the medicine tank 2. The rack 25 and the gear 24 mesh with each other. A bent rod 17 is fixedly connected to the outside of the gear 24. The output end of the electric push rod 26 is retracted, thereby driving the rack 25 to move backward and driving the gear 24 to rotate. This causes the bent rod 17 connected to the gear 24 to fall into the housing 16, allowing the medicine to slide down. At the same time, the bent rod 17 at the rear rises to block the medicine behind. After the medicine slides down, the electric push rod 26 returns to its extended state, and the bent rod 17 at the front rises while the bent rod 17 at the rear falls into the housing 16. At this time, the bent rod 17 at the front blocks the medicine behind, so that only one box of medicine falls at a time, preventing multiple boxes of medicine from falling.

[0034] Reference Figure 1 - Figure 6The bottom of the medicine tank 2 is fixedly connected to a housing 16. An electric push rod 26 is installed inside the housing 16. The lifting assembly includes a housing 8, which is fixedly connected to the outside of the outer shell 1. Two chain discs 28 are rotatably connected inside the housing 8. A motor 15 is fixedly connected to the outside of the housing 8. One of the chain discs 28 is fixedly connected to the output end of the motor 15. The motor 15 drives one of the chain discs 28 to rotate. Chains 9 are sleeved on the outer periphery of the two chain discs 28. The chains 9 have good mobility and high rigidity, making it easier to fix other parts on them. The feeding assembly includes a roller 11, which is fixedly connected to the outside of the housing 8. A slide rail 13 is fixedly connected to the right side of the roller 11. A fixing rod 12 is fixedly connected to the inner side of the slide rail 13. A storage tray 14 is fixedly connected to the bottom of the slide rail 13. Medicines can slide down the roller 11 and slide rail 13 onto the storage tray 14. The slide rail 13 can be extended or its shape changed as needed to position the storage tray 14 appropriately. A connecting plate 5 is rotatably connected to the outside of the chain 9. Multiple crossbars 6 are fixedly connected to the outside of the connecting plate 5. A slide bar 10 is fixedly connected to the front of the housing 8. A fixed frame 3 is slidably connected to the outside of the slide bar 10. The connecting plate 5 is slidably connected to the middle of the fixed frame 3. Through the cooperation of the fixed frame 3 and the slide bar 10, the connecting plate 5 in the middle is always in a horizontal state, which will not cause the medicine on it to fall off. A tray 7 is fixedly connected to the outside of the housing 1. The tray 7 is used to temporarily hold the medicine conveyed by the conveyor belt 4 and facilitates the lifting component to take the medicine away.

[0035] Working principle: First, different medicines are placed into the medicine tank 2, which is connected to the outer shell 1 via a straight rod 29. When the device receives an instruction, the instruction is implemented by the controller, sensor, and control program (this is existing technology and will not be elaborated further). The motor 23 behind the base 21 starts to rotate, driving the crankshaft 22 to rotate. The crankshaft 22 drives the slider 19 to continuously push the top block 20 up. The top block 20 will continuously hit the bottom of the medicine tank 2. In conjunction with the spring 27 connected to the top block 20 and the telescopic rod 18, a pulling force is continuously applied to the pushed-out top block 20, causing the medicine tank 2 to vibrate. At the same time, the electric push rod 26 retracts its output end, thereby driving the rack 25 to move backward and driving the gear 24 to rotate. This causes the front curved rod 17 connected to the gear 24 to fall into the housing 16, allowing the medicine to slide down. Simultaneously, the rear curved rod 17 rises to block the medicine behind. After the medicine slides down, the electric push rod 26 extends back. In this state, the front curved rod 17 is raised and the rear curved rod 17 is lowered into the housing 16. At this time, the front curved rod 17 blocks the medicine behind, and the medicine sliding out of the medicine tank 2 falls onto the conveyor belt 4. The conveyor belt 4 transports the medicine to the tray 7. At this time, the chain disc 28 inside the housing 8 is driven by the motor 15, which makes the chain 9 meshing with it rotate. The connecting plate 5, which is fixedly connected to the chain 9, is fixed in a horizontal state and moves with the chain 9 under the fixation of the fixed frame 3 controlled by the two slide rods 10. When it rotates to the position of the tray 7, the multiple crossbars 6 on the connecting plate 5 will pass through the gaps between the multiple crossbars 6 connected to the tray 7 and take the medicine away. When it rotates to the position of the roller 11, the crossbars 6 will still pass through the gaps in the roller 11 and leave the medicine on the roller 11. Then the medicine on the roller 11 will slide into the storage tray 14 along the slide 13 connected to the fixed rod 12. Then the doctor can directly get the required medicine from the storage tray 14.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
