The invention relates to the field of automatic production, in particular to an automatic lifting and rotating device which comprises a lifting mechanism and a rotating mechanism mounted at the top ofthe lifting mechanism. The lifting mechanism comprises a fixed sleeve, a lifter and a lifting movement component arranged in the fixed sleeve, and the lifter for driving the lifting movement component to extend and contract is fixedly mounted on the side wall of the fixed sleeve; the rotating mechanism comprises a rotating support, a driving motor and a rotating component, the driving motor and the rotating component are respectively mounted on the rotating support, and a pot cover is mounted at the tail end of the rotating component. The device can realize automatic lifting and lowering starting and stopping and rotating angle adjusting of the pot cover, so that labor intensity of operating personnel is lowered greatly, potential safety hazards caused when the pot cover of a steamer potis opened manually are avoided, and the device is suitable for further popularization and application.
