Automatic correcting device of high-efficiency brushing machine

The utility model relates to an automatic fabric deviation rectifying device of high efficient carder, which consists of two photo-sensors, two magnetic valves, two cylinders, a transverse rail, two side columns, two side crossbeams, two back plates, a dossal roller and fabric. The transverse rail is arranged between the two side columns and behind the fabric, being in parallel with the plane of the fabric. The two back plates are respectively fixed between the two side crossbeams and the two side columns. The two cylinders are respectively fixed on the two back plates and connected with the two ends of the dossal roller. The two ends of the transverse rail are respectively installed with a photo-sensor. The two photo-sensors are respectively and electrically connected with the two magnetic valves which are respectively and pneumatically connected with the two cylinders. The fabric is winded on the semi-circumference of the dossal roller and the two cylinders are respectively used for controlling the uplift o
