[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] according to Figures 1 to 4 As shown, an exhaust mechanism for a decoction machine includes a fixed frame 1. The fixed frame 1 includes an annular plate 2 and a rotating plate 3 disposed opposite to each other within the annular plate 2. The annular plate 2 is fixed to its bottom surface. A rotating motor is installed below the rotating plate 3, driving the rotating plate 3 to rotate relative to the annular plate 2. A gap exists between the annular plate 2 and the rotating plate 3. A station rotation groove 4 for suspending a self-standing suction nozzle medicine bag 7 is provided on the side of the rotating plate 3 near the annular plate 2. A guide block 20 is fixedly connected to the annular plate 2, opposite to the station rotation groove 4, ensuring that the self-standing suction nozzle medicine bag 7 is aligned with each station for operation. The exhaust assembly includes a capping assembly and an exhaust assembly fixedly mounted on the fixed frame 1. The capping assembly is located above the station rotation groove 4, and the exhaust assembly is located below the station rotation groove 4. A monitor 8 is fixedly mounted on the annular plate 2, opposite to the self-standing suction nozzle medicine bag 7. The monitor 8 can detect whether there is a cap 21 on the self-standing mouthpiece medicine bag 7. If there is a cap 21, it can vent and screw on to seal. If no cap 21 is detected, the machine will stop running to prevent the medicine from spilling and ensure the safety of the medicine.

[0022] The cap assembly includes an upper and lower drive component and a rotation drive component. The rotation drive component is fixed to the upper and lower drive component, which in turn is fixed to a mounting bracket 1. The upper and lower drive component can drive the entire rotation drive component to move up and down. The upper and lower drive component includes a fixed rod 13, a guide rod 14, a drive rod 15, and a drive cylinder 16. The drive cylinder 16 is fixedly sleeved on the drive rod 15 by fixing bolts. The drive rod 15 is sleeved on the fixed rod 13. The drive rod 15 has internal threads, and the fixed rod 13 has external threads. The drive rod 15 and the fixed rod 13 move helically. One end of the fixed rod 13 is connected to a second drive motor 17, which drives the fixed rod 13 to rotate. The drive cylinder 16 is slidably connected to the guide rod 14, which is fixed to the mounting bracket 1. The rotation drive component is fixedly connected to the drive cylinder 16. When the fixed rod 13 rotates, the drive rod 15 moves up and down in cooperation with the guide rod 14 to drive the drive cylinder 16 to move up and down, thus realizing the up and down movement of the rotation drive component. The rotation drive component includes a drive motor 18 and a motor shaft 19. The locking cover 5 is fixedly connected to one end of the motor shaft 19. The locking cover 5 is arranged opposite to the station rotating groove 4. Under the drive of the upper and lower drive component and the rotation drive component, the locking cover 5 can be fitted with a cover, moved away from the cover, and rotated, so as to realize the upper and lower extension and rotation movement of the locking cover 5.

[0023] Example 1 of the exhaust assembly, such as Figure 3 As shown, the exhaust assembly includes two exhaust plates 6, four rotating gears 12, and an exhaust bracket 9. The exhaust bracket 9 has a groove 901 and is fixed to a mounting frame 1. The two exhaust plates 6 are rotatably mounted on the exhaust bracket. Two rotating shafts 10 are mounted on the exhaust bracket 9, one of which is connected to a drive motor 11. The two exhaust plates 6 are respectively fixed to the two rotating shafts 10. One end of each exhaust plate 6 is fixedly connected to a rotating shaft 10 and located within the groove 901. Both ends of the rotating shafts 10 are rotatably fixed to the groove 901. A pair of rotating gears 12 are fixedly connected to each of the two rotating shafts 10, and the rotating gears 12 are located between the exhaust plates 6 and the grooves 901. The exhaust plates 6 are flat plates, and each exhaust plate 6 has an exhaust hole 602 and an exhaust wall 603. The exhaust hole 602 is located below the exhaust wall 603, which is opposite to the middle of the self-standing mouthpiece medicine bag 7. The exhaust hole 602 is opposite to the lower end of the self-standing mouthpiece medicine bag 7.

[0024] Example 2 of the exhaust assembly, such as Figure 5 As shown, the exhaust plate 6 has a gear portion 601 integrally formed. The gear portion 601 is fixedly connected to the rotating shaft 10 and located in the groove 901. A rotating pad is provided between the gear portion 601 and the exhaust bracket 9. An exhaust hole 602 and an exhaust wall 603 are formed at the end of the exhaust plate 6 away from the gear portion 601. The exhaust hole 602 is located between the exhaust wall 603 and the gear portion 601.

[0025] The air venting assembly and the capping assembly work together to expel the air from the self-standing mouthpiece medicine bag 7, and then the capping assembly seals the self-standing mouthpiece medicine bag 7 and the cap, saving time and reducing the contact time between the medicine and excessive air, making the medicine bagging process more efficient and convenient, and ensuring the quality of the filled medicine.
