The invention relates to a rewinding and winding production line for parts in the rubber product production process. The automatic on-line rewinding and winding production line comprises a plurality of winding stations, a conveying belt and a control system which are arranged in sequence. The conveying belt penetrates through the tops of the multiple winding stations. A conveying belt frame is arranged on the two sides of the conveying belt. The conveying belt is divided into a plurality of sections. A blanking notch is formed between each two adjacent sections. A blanking notch is formed in the top of each winding station. A movable swing frame and an automatic rubber material cutter are arranged at each blanking notch in sequence. According to the automatic on-line rewinding and winding production line, by adding the movable frames and rotating platforms, winding and rewinding operation can be conducted synchronously, an original mode of operation through two people is turned into a mode of operation through one person, so that the operator quota during the rewinding operation is decreased; through the design of the rotating platforms, the repeated carrying work of workers is reduced, the labor intensity of the workers is reduced, and the production efficiency is improved by 30% or above.
