The invention discloses a rotating valve column loading mechanism of electronic drain valve assembly equipment. The rotating valve column loading mechanism of the electronic drain valve assembly equipment comprises a rotating valve column frame, a rotating valve column vibration disc, a rotating valve column feeder, a rotating valve column bracket, a rotating valve column vibrator and a rotating valve column loading device; the rotating valve column vibration disc is mounted on the rotating valve column frame; the rotating valve column feeder is arranged in a discharge port of the rotating valve column vibration disc; the rotating valve column bracket is arranged on the rotating valve column frame below the rotating valve column feeder; the rotating valve column vibrator is mounted on an upper flat plate of the rotating valve column bracket; the rotating valve column feeder is mounted on the rotating valve column vibrator; and the rotating valve column loading device includes a loading bracket, a loading slide table bracket, a loading revolving cylinder, a rotating valve column lifting cylinder and a pressing module. Through the mode, the rotating valve column loading mechanism of the electronic drain valve assembly equipment is compact in structure, can replace manual operation to automatically displace rotating valve columns, saves labors, and reduces the production cost.
