Automatic feeding mechanism of graphite rod extruder

The invention belongs to the technical field of extruders, and discloses a graphite rod extruder automatic feeding mechanism which comprises an extruder shell, and a main shaft is arranged in the extruder shell; the feeding hole is formed in the top of the extruder shell; and the material control mechanism comprises a feeding hopper, the bottom of the feeding hopper is fixedly connected with the top of the extruder shell, a cavity is formed in the lower portion of the interior of the feeding hopper, and the right end of the interior of the cavity is movably connected with a material control plate in a sleeved mode. By arranging a material control plate, a round hole, a notch and a clamping block, the bottom end of the clamping block can be clamped into the notch, movement of a main shaft can pull the material control plate and a mounting box to integrally move rightwards, so that a feeding port is aligned with the round hole, and at the moment, a graphite raw material in a feeding hopper can enter an extruder
