The device comprises a bottom frame and a first supporting frame, one side of the bottom frame is fixedly connected with a winding frame, one side of the top end of the bottom frame is fixedly connected with the first supporting frame, the other side of the top end of the bottom frame is provided with an auxiliary forming structure, and one side of a gluing structure is provided with a limiting seat. The auxiliary cutting mechanism is arranged, when the bottom of an electric telescopic rod extends downwards and pushes a blade to cut the carbon fiber prepreg cloth below, the blade is kept vertical under limiting of a limiting piece, and a pressing plate firstly makes contact with the carbon fiber prepreg cloth during downward moving cutting; along with continuous downward movement of the blade, the supporting plate presses a first pressing spring downwards, the elastic force of the first pressing spring acts on a pressing plate in the reverse direction, pressing of the pressing plate on the carbon fiber prepre
