Automatic feeding device with demagnetization function for tapered roller production

The utility model relates to the technical field of tapered roller production, in particular to an automatic feeding device with a demagnetization function for tapered roller production, which comprises a concave strip, a long groove is formed in the middle of the inner wall of the concave strip, and a long strip is rotatably connected to the middle of the rear side of the concave strip. According to the tapered roller machining device, a tapered roller needing to be machined is inversely arranged on the bottom face of the inner wall of the concave strip, the long strip, the L-shaped blocking strip, the protruding block, the second threaded rod and other structures are matched, the motor is started to drive the protruding block to rotate, and when the protruding block makes contact with a transverse strip of the L-shaped blocking strip, the L-shaped blocking strip moves upwards through the long groove to block the tapered roller; when the protruding position of a protruding block moves to the lower side, an L
