Detailed ways:

A coating machine, characterized in that it includes a cabinet 1, a cabinet door 2 hingedly connected to the cabinet, a hollow cylindrical drum 3, and a driving device fixedly installed in the cabinet and connected to the drum in rotation to drive the drum to rotate 4. The liquid spray pipe 5 for spraying the outer layer of paint to the medicine in the drum and the hot blower 6 for drying the paint. The circumferential side wall of the drum is hollowed out, and the liquid spray pipe passes through the door and is fixed with the door Connected, the end of the liquid spray pipe is provided with a liquid spray atomization adjustment nozzle 51 and when the box door is closed, the liquid spray atomization adjustment nozzle can extend to the inside of the drum, and the hot blower air outlet 61 is arranged close to the side wall of the drum.

The driving device can be a motor, a handwheel, etc., which can drive the drum to rotate through belt transmission, gear transmission, etc., so that the medicine in the drum rolls, and the surface of the medicine contacts with the coating liquid and is covered by the coating liquid; the circumference of the drum The side wall is hollowed out, and the hot air blown by the blower can pass through the circumferential side wall of the drum to heat the medicine after spraying the coating liquid, so that it can be dried quickly, and the coating is dried and fixed, and the blower can blow the tablet, further making it Tumble and fully contact with the coating liquid; the coating liquid is transported to the spray liquid atomization adjustment nozzle through the liquid spray pipe, and sprayed out after being atomized
