The invention relates to an automatic bottle-feeding system, in particular to an oral liquid sterilizing automatic bottle-feeding system and belongs to the field of medical devices. The oral liquid sterilizing automatic bottle-feeding system comprises a machine frame, a motor and an electrical control system. The machine frame (2) is fixed with a bottle tidying table support frame (7), a bottle tidying mechanism (5) is arranged at the top of the bottle tidying table support frame, one end of the bottle tidying mechanism corresponds to a bottle pushing mechanism (8), the other end of the bottle tidying mechanism (5) corresponds to one end of a sterilizing disc (4), the other end of the sterilizing disc (4) corresponds to a bottle blocking mechanism (1), a sterilizing disc blocking rod (14) is arranged between the sterilizing disc (4) and the bottle tidying mechanism (5), a blocking rod automatic taking and placing mechanism (13) is installed at the top of the sterilizing disc blocking rod, the sterilizing disc is arranged at the top of a sterilizing disc conveying unit (3), and the sterilizing disc conveying unit is arranged on the upper portion of the machine frame. Through the oral liquid sterilizing automatic bottle-feeding system, automatic tidying and automatic feeding of oral liquid penicillin bottles and automatic taking and placing of the open type sterilizing disc blocking rod are achieved, production efficiency is improved, labor intensity is reduced, and production cost is low.
