Then, the nozzle 22 injects a certain amount of medicine into the capsule forming groove 32, and the two groups of hollow roller molds 31 squeeze the capsule into shape; after the capsule is formed, the electric contacts 35 in the hollow roller mold 31 are separated from the position of the fan-shaped block 37 in turn, and the electric heating strip 33 is powered off and stops heating the corresponding part of the hollow roller mold 31, saving energy consumption.

Then, the nozzle 22 injects a certain amount of medicine into the capsule forming groove 32, and the two groups of hollow roller molds 31 squeeze the capsules into shape. After the capsules are formed, the electric contacts 35 in the hollow roller mold 31 are separated from the positions of the fan-shaped blocks 37 in turn, and the electric heating strips 33 are powered off and stop heating the corresponding parts of the hollow roller mold 31. The formed capsules fall into the discharge channel 42 in turn, and the air cooler 44 cools the capsules in the discharge channel 42 to facilitate rapid cooling and shaping of the capsules. The formed and cooled capsules fall into the receiving box 45 for unified collection.
