The invention provide a film conveying deviation-rectifying device combining the tension control, which comprises a film input guiding roller, an output guiding roller, a deflection detecting mechanism, a tension detecting mechanism, a controller and a deviation-rectifying actuating mechanism, wherein the film input guiding roller and the output guiding roller are used for inputting a film guide into the deviation-rectifying actuating mechanism and outputting the film guide from the deviation-rectifying actuating mechanism; the deflection detecting mechanism is used for detecting whether the film deflects or not; the tension detecting mechanism is used for detecting the film tension; the controller is used for generating deviation-rectification or/and tension control instruction as per the detection information; the deviation-rectifying actuating mechanism comprises a spherical motor, a deflection frame and a deviation-rectification roller; a runner of the spherical motor drives the deflection frame to rotate on a feeding surface of the film; the friction between the rectification roller and the film drives the inverse rotation of the film to realize the deviation-rectification; meanwhile, the runner of the spherical motor drives the deflection frame to rotate on the surface vertical to the feeding surface of the film, so as to tighten or loose the film to realize the tension control. According to the invention, the deviation-rectification and the tension control of the film can be realized simultaneously, the influence of the tension variation on the deviation-rectification is greatly reduced, the structure is simple, and the deviation-rectifying precision is high.
