The invention discloses a preparation and packaging machine for traditional Chinese medicine powder, which includes a No. 1 motor, a crushing cylinder, a connecting rod, a crushing blade, a plug plate, a grinder, a discharge pipe, a solenoid valve, a conveyor belt, a packaging tank, a hot air blower, and a No. 2 motor , nano-microporous composite material layer, hydraulic cylinder, grinding workpiece, blast hood, sealing cover and feeding pipe, the No. 1 motor drives the crushing blade on the connecting rod to rotate, and crushes the herbs inside the crushing cylinder, pull out the plug Plate, pour the herbal medicine inside the crushing cylinder into the grinder, the hot air will dry the medicine in the grinder first, and the water vapor will pass through the nano-microporous composite material layer and go to the outside of the grinder to ensure that the crushed medicine will be dried before grinding. Keep dry for easy grinding. The blast hood can expand the blowing surface of the hot air blower, and the No. 2 motor drives the hydraulic cylinder to rotate, and the grinding workpiece can be lifted up and down through the hydraulic cylinder, thereby realizing the effect of fine grinding.
