Adjustable rotating mechanism for winding composite material

The invention relates to an adjustable rotating mechanism for winding composite materials, which comprises a headstock, a tailstock and a driving motor, the distance between the headstock and the tailstock is adjustable, the headstock is further provided with a speed reducer, a coupler and a bearing seat, and an output shaft of the driving motor is sequentially connected with the speed reducer and the coupler. A connecting shaft is arranged on the bearing seat, one end of the connecting shaft is connected with the coupler, the other end of the connecting shaft extends out of the bearing seat and is provided with a chuck used for being fixedly connected with one end of a workpiece, a tailstock with a tip is further arranged on the lathe tailstock, and the other end of the workpiece is ejected through the tip. And a supporting seat for supporting the other end of the workpiece is also arranged on the tailstock. Compared with the prior art, the winding machine can be used for winding composite materials on large
