The invention belongs to the technical field of pharmaceutical machinery. Disclosed are a hopper butt-joint sealing structure and an implementation method thereof. In order to solve the problems that the hopper butt joint is generally fixed by means of a hoop, etc., manual operation is needed, the efficiency is lower, and the possibility of contamination is increased, a lifting driving mechanism is connected between a hopper cover and a support, and an inflatable sealing ring is connected to the periphery of an annular mating plate in a limiting manner. When a butt joint is required for discharge, the control system controls the lifting driving mechanism to descend and move the hopper cover relative to the support until the inflatable sealing ring is located in an inlet of a receiving container, and then controls an air pipe to inflate the inflatable sealing ring for sealing. Upon completion, the air pipe is controlled to extract air from the inflatable sealing ring so that the inflatable sealing ring is in a sealing releasing state, the lifting driving mechanism is controlled to raise the hopper cover relative to the support to leave the receiving container, and the receiving container is removable. The working efficiency can be improved, and the contamination caused by manual operation is avoided. The sealing structure is reliable, and has a wide application scope, with no precision requirements for the inlet of the receiving container.
