This invention relates to a dispensing device and method for a medicine dispensing machine, addressing the technical problem in existing unmanned medicine vending machines where the saddle-top dispensing structure uses a built-in motor to push the medicine out of the dispensing channel. This requires a motor in each channel, resulting in complex structure and high manufacturing costs. The invention provides a dispensing device and method for an unmanned medicine vending machine. A push rod is mounted inside the housing via a rotating shaft. One end of the push rod has a push plate, and the housing has a push plate hole. The other end of the push rod has an arc-shaped rod. A drive plate is also slidably mounted inside the housing. A drive hole is provided in the housing for an external contact to extend into the housing and push the drive plate to slide within the housing. A pressure plate is provided on the upper surface of the drive plate, and the lower surface of the pressure plate is in contact with the upper surface of the arc-shaped rod to compress the arc-shaped rod, causing the push plate to extend out of the push plate hole and lift the bottom of the medicine box to be flush with the top of the baffle.
