Equipment doors are transformed based on the conditions that the mechanical doors of certain mechanical equipment do not have a visual function, the doors are inconvenient to open and close, and the sound insulation and noise reduction ability is poor. The overall structure of the automatic control door serving as a mechanical protective door matched with the mechanical equipment is made of an aluminum profile, so that the whole is light and operation staff can conveniently open or close the automatic control door. Work staff watch the operation conditions of the equipment through organic glass on the door. The automatic control door is connected with the machine body of the used equipment, and sound insulation and noise reduction are conducted on the equipment on every side. The automatic control door can move up and down when being pulled and stop freely, so that not only can the surrounding work staff be effectively protected, but also the equipment is convenient to operate and maintain.
