Chinese medicine has long cultural source and rich resources, but China only accounts for a few of the traditional Chinese medicine export amount in the world at present, and the main reason is that the Chinese still adopts the original medicine dispensing mode of crude drugs, hand grasping and scale weighing, and the Chinese medicine dispensing process has low speed and large metering error and is difficult to meet the international market of standardization, standardization and scientization of medicine dispensing.

Along with the scientific and technological development, some hospitals begin to use mechanical automatic medicine dispensing, in order to satisfy the demand that mechanized medicine dispensing, current medicine dispensing machine adopts the fixed medicine box of shape, and traditional chinese medicine is sealed through the plastic film to the medicine box surface after packing into the medicine box. However, the medicine box occupies a large space, has high cost and is inconvenient to carry, and if a bag-packed mode is used, the cost can be saved and the medicine box is convenient to carry.

The existing bag packaging methods mainly comprise two types, namely, the opening of the prepared packaging bag is opened by using a vacuum chuck and other modes before dispensing. However, the mechanical structure involved in this method is complicated, the opening effect is not controllable, and the dosage is easy to leak due to incomplete opening. The vacuum chuck has high noise, affects the work of doctors and does not meet the use requirement of the pharmacy in hospitals. The other opening method is to open the bag mouth by using a structure similar to a funnel shape, but the mechanism for opening the bag mouth can pollute the medicine bag and is not suitable for the pharmacy dispensing field with continuously changed formulas. And the second is to wrap the surface of the product directly by using a packaging film and then seal the product into a bag.
