The invention discloses an automatic feeding and discharging device, a table type lifting type sintering furnace and an automatic feeding and discharging system. The automatic feeding and discharging device comprises a fixing base, a lifting table is fixed to the fixing base, wherein the lifting table is rotatably and fixedly connected with a tray, the tray is provided with notches along the rotating direction. The table type lifting type sintering furnace comprises at least one automatic feeding, and further comprises a liftable furnace bottom, a sintering support is arranged on the furnace bottom, supporting legs are arranged on the sintering support, and the diameters of the arc-shaped notches are larger than that of the supporting legs. According to the automatic feeding and discharging device, the table type lifting type sintering furnace and the automatic feeding and discharging system, the high-temperature potential safety hazard existing in manual operation is reduced, the utilization rate of the table type lifting type sintering furnace is effectively improved, the problems of unsafety and low efficiency caused by manual feeding and discharging can be solved.
