The invention discloses an electronic deviation rectifying device used in glass fiber wallhanging cut trimming, consisting of a control system and an execution system. The control system comprises at least two color mark sensors, a programmable controller, a transducer, and a revolving coder; the execution system is composed of an execution motor frame, a slide bar frame, a sensor frame, a cuttersaddle, an execution motor, a screw mandrel and a cutter. After any of the color mark sensors detects color streak which serves as a color mark inlaid along the edge on the upper surface at one side of the edge to be cut of the wallhanging, the color mark sensor sends the location information to the programmable controller to control the movement of the cutter, so as to rectify deviation. The signals of the color mark sensors can be used in high speed deviation rectification and low speed deviation rectification. The revolving coder feeds back the detected speed of the threads of the wallhanging to the programmable controller to control the movement speed of the cutter, so as to ensure the constant ratio of deviation rectification to the speed of the threads of the wallhanging. The electronic deviation rectifying device realizes automated control to deviation rectification and is high in rectification precision, stable in performance, simple in operation and installation and low in making cost.
