[0002] With the development of medicine and the advancement of medical methods, traditional Chinese medicine has also received widespread attention and love. The demand for traditional Chinese medicine in the medical field is also increasing. During the decoction process, traditional Chinese medicine has certain requirements on decoction utensils, water, heat, and cooking methods. The decoction time is also relatively long, which is not suitable for modern living environment. For this reason, traditional Chinese medicine is usually made into powder and taken by brewing. This can greatly reduce the time while also ensuring the efficacy.

[0003] With the diversification of Chinese medicine products, the number of Chinese medicine powder products has increased, and Chinese medicine powder is easier for people to accept. Powder is also of great significance to the popularization of Chinese medicine. In order to enable batch production and packaging of Chinese medicine powder, there are various powder packaging machines on the market. At present, the demand for small-dose packaging of different Chinese medicine liquids produced for different patients and different diseases after powdering is gradually increasing, and the demand and requirements for powder packaging machines are also gradually increasing.

[0004] The traditional Chinese medicine powder packaging on the market now usually adopts ordinary packaging machines, which have single functions, cannot adapt to one prescription for one person, and require frequent material changes.

The packaging bag is transmitted in the middle of the rubber-wrapped wheels 32 and is driven by the rubber-wrapped wheels 32 to continue to be transmitted. The packaging bag maintains a certain tension during the transmission process through the mutual cooperation of the bag pulling motor 31 and the roll feeding motor 22. When the packaging bag is wrinkled during the transmission process, the rotation of the roll feeding motor 22 is reduced or stopped, and the bag pulling motor 31 maintains a constant speed to gradually straighten the packaging bag. Then, the roll feeding motor 22 and the bag pulling motor 31 are rotated synchronously to always keep the packaging bag in a stretched state.

[0052] In this embodiment, the sealing and cutting device 4 is arranged below the bag pulling device 3 in the vertical direction, and the sealing and cutting device 4 includes a sealing and cutting motor 41 and a cam connecting rod device 42.

The photoelectric switch 24 is used to detect the tension of the packaging bag during the transmission process. The tension of the packaging bag is controlled by the roll feeding motor 22 and the photoelectric switch 24. The photoelectric switch 24 is U-shaped. During the transmission process of the packaging bag, a portion of the packaging bag is kept in the U-shaped opening. When wrinkles appear in the packaging bag during transmission and touch the photoelectric switch 24, the roll feeding motor 22 stops running, the packaging roll 23 stops conveying, and the bag pulling motor 31 keeps running to pull the packaging bag to make it flat, thereby ensuring the tension state during the transmission process. After the packaging bag is away from the photoelectric switch 24, the roll feeding motor 22 continues to run, driving the packaging roll 23 to move and conveying the packaging bag.

[0057] In this embodiment, a sensor 25 is further provided between the four transmission rollers, and the sensor 25 is used to detect the transmission length of the packaging roll 23.

The photoelectric switch 24 is arranged between the second transmission roller and the third transmission roller along the conveying direction. Two sensing blocks extend from both ends of the photoelectric switch 24 corresponding to the two sides of the packaging bag. When the wrinkles of the packaging bag touch the sensing blocks due to tension during the conveying process, the roll feeding motor 22 stops. When the packaging bag is away from the position of the sensing block, the roll feeding motor 22 continues to work to transport the packaging bag, so that the packaging bag between the two motors is always in a tensioned state to avoid wrinkles in the packaging bag.

[0060] In this embodiment, a sensor 25 is provided in the middle of the four transmission rollers 21 of the roll feeding device 2, which is used to detect the transmission length of the packaging bag and whether there are any remaining packaging bags. When the transmission length of the packaging bag reaches the set value of the set packaging parameter, the bag pulling motor 31 stops running. After the material transmitted by the unloading device 5 falls into the packaging bag, the sealing and cutting motor 41 drives the cam connecting rod device 42 to make the heat sealing block move relative to cut and package the packaging bag, and the packaged material falls into the storage device through the discharge port.
