The invention relates to the technical field of electronic component machining equipment, in particular to a carrying and feeding device for a network transformer. The carrying and feeding device is used for placing the network transformer located in a material pipe into a cavity of a material belt and comprises an inclined slide rail and an installation plate; the top end of the slide rail is provided with a clamping part for clamping the material pipe, and the bottom of the slide rail is sealed; a driving motor is fixedly installed on one side of the installation plate, and the other side of the installation plate is further provided with a rotary table, a guide rod and a guide rod seat; the rotary table is fixedly installed on a rotary shaft of the driving motor; the guide rod seat is movably installed on the installation plate through a hinged shaft; the guide rod penetrates through the guide rod seat to be hinged to the rotary table; a suction nozzle is fixedly installed at the bottom end of the guide rod, and a vacuum pump is connected to the suction nozzle through a pipeline; and the pipeline is provided with an electromagnetic valve controlled by a controller, the controller controls the driving motor to rotate clockwise and counterclockwise intermittently, and accordingly, the suction nozzle sucks and carries the network transformer in the slide rail periodically into the cavity of the material belt.
