[0028] Working process:
[0029] 1. When the reclaimer starts to move, the stirring device starts to move synchronously.
[0030] 2. The motor drives the driving shaft to rotate, the driving shaft drives the stirring shaft to rotate, and the stirring shaft drives the medicinal materials in the hopper to move, avoiding the formation of material bridges and allowing the medicinal materials to fall smoothly.
[0031] 3. When the reclaimer stops working, the stirring device also stops working synchronously.
[0032] The motor in the upper discharging and medicine taking device drives the composite conveyor belt to rotate. The baffle on the composite conveyor belt takes the medicinal slices out of the hopper like a spoon, passes through the limiting spring piece and the inner material cover, and the excess medicinal slices are blocked in the hopper under the action of the limiting spring piece and the inner material cover, so that the baffle usually only takes out one or one medicinal slice, thereby achieving the requirement of accurate measurement.
[0033] The motor in the lower discharge and medicine dispensing device drives the composite conveyor belt to rotate. The steel nails on the composite conveyor belt carry the medicinal slices out and pass through the pressure roller assembly on the hopper. Under the action of the pressure roller, the excess medicinal slices are blocked in the hopper, ensuring that the steel nails only carry out medicinal slices of a certain height, thereby achieving the requirement of accurate measurement. The medicinal slices pass through the discharge cover and fall into the scale pan in the metering, pushing and flipping device. When the weight of the medicinal slices on the medicine pan on the scale pan is greater than or equal to the set value for the rough medicine dispensing, the lower discharge and medicine dispensing device begins to jog and dispensing medicine. When the required weight is reached, the metering and pushing device stops measuring, the lower discharge and medicine dispensing device stops operating, and the stirring device stops stirring.
