摘要

PURPOSE: A contactless baffle device for an air knife is provided to be suitable for emergency or maintenance since a baffle plate is formed to be able to be moved back.;CONSTITUTION: A contactless baffle device(100) for an air knife consists of a body(110), a moving body(120), a baffle plate(130), an actuator(140), a shaft(150), a driving motor(160), a sensor(170), a plurality of guide rollers, a bracket, a roller, a spiral shaft and a handle. A guide rail is installed on the lower part of the body in a horizontal direction. The baffle plate is installed on the lower part of the moving body. The guide rollers make contact with the upper and lower parts of the guide rail, smoothly rotate and move. The roller member of the bracket is formed on one side of the moving body to be able to move back and forth. The spiral shaft moves the bracket back and forth.
