The invention discloses an electrical automation blanking device. The electrical automation blanking device comprises a blanking bin, a leading-out box, a motor and a control panel. The motor is arranged on the right side of the control panel, a rotary shaft is arranged on one side of the motor, a limiting rod is installed on a rotary shaft, an upper feeding box is arranged above the limiting rod,a lower feeding box is arranged below the limiting rod, and the leading-out box is connected with the position below the lower feeding box; a motor shaft is arranged at the center of the motor, a stator handle is arranged in the motor, spring pieces are arranged on the two sides of the stator handle correspondingly, moving contacts are arranged on the lower portions of the spring pieces, and static contacts are arranged on the lower portions of the moving contacts. According to the electrical automation blanking device, the limiting rod is arranged, the motor generates torsion, up-down compression of the limiting rod is controlled, then returning is conducted through elastic force of a torsional spring, so that a material of the blanking bin enters a feeding bin, the size of an opening which is exposed out is adjusted by utilizing the distance moved by the limiting rod, so that the blanking speed of the electrical automation blanking device is controlled, meanwhile the motor drives material measuring and taking and blanking, the structure is simple, and the automation degree is high.
