The invention belongs to the technical field of machines, and provides an automatic feeding and discharging device of a type rolling machine. The device comprises a drive element, a drive element installation support, a limiting mechanism, a feeding mechanism, a reset mechanism and a discharging mechanism. The drive element controls the feeding mechanism and the discharging mechanism to move up and down in a reciprocating mode, the feeding mechanism and the discharging mechanism are rotationally connected, the feeding mechanism is connected with the drive element installation support in a sliding mode through the limiting mechanism, and the reset mechanism controls the discharging mechanism to return to the original position. By means of the arrangement of the feeding mechanism and the discharging mechanism, feeding and discharging are combined in the type material rolling process, time is saved, the work tact of the type rolling machine is reduced, materials can be pushed to be discharged through the discharging mechanism, the discharging mechanism also has a certain bearing function on the materials to be machined, discharging is accurate, consumed time is short, and efficiency is high; by means of the arrangement of the limiting mechanism and the reset mechanism, it is guaranteed that the automatic feeding and discharging device is safe, stable and high in reliability in the feeding and discharging processes.
