Feeding mechanism of tablet press

The utility model relates to the technical field of feeding, and discloses a feeding mechanism of a tablet press, which solves the problems that the conventional tabletting processing mechanism is not provided with a sealing component, cannot separate materials, is easy to accumulate outside a mold and affects material processing. According to the feeding device, the first motor drives the concave rod to rotate, the sealing ball is not connected with the feeding pipe in a sealed mode any more, then materials in the feeding base are led out, when the concave rod rotates downwards, the supporting rod drives the sealing ball to move downwards to the interior of the feeding pipe, and therefore the materials in the feeding pipe can be cleaned. And meanwhile, under the elastic potential energy of the spring, the sealing ball and the feeding pipe are connected more tightly, and under the sealing arrangement of the powder falling prevention assembly, the situation that materials fall out of the mold from the feeding
