Angle type tension control method and device for stable conveying of carbon fiber prepreg tape

Abstract

The invention discloses an angle type tension control method and device for stable conveying of a carbon fiber prepreg tape. The device comprises an unwinding motor, a backing paper collecting roller,a swing rod mechanism, a tension buffering mechanism, an angle detection mechanism and a control system, wherein a material roll is connected with the unwinding motor, the carbon fiber prepreg tape on the material roll is actively unwound by the unwinding motor, is wound around the backing paper collecting roller to realize separation of the prepreg tape and backing paper, and then enters the tension buffering mechanism through the swing rod mechanism, and the angle detection mechanism is used for converting the change of the tension in the carbon fiber prepreg tape into the change of the angle size, and feeding back the change of the angle size to the control system in real time so as to realize tension control. According to the method and the device, through small-displacement and large-angle conversion, the rapid response of tension control can be improved, the response of control can be greatly improved, and the tension can be rapidly adjusted and controlled; and the structure issimple, the prepreg tape can be conveniently wound, the working efficiency is high, and meanwhile, the occupied space in a creel is saved.
