This invention relates to the field of photovoltaic cable manufacturing technology, specifically to a production device for photovoltaic cables, comprising a housing with outlet holes and several inlet holes on the side wall of the housing, and a take-up assembly and a pay-off assembly outside the housing; a fixed cylinder is fixedly connected inside the housing, and a rotating cylinder is sleeved on the outside of the fixed cylinder, with several wire-passing grooves on the side wall of the rotating cylinder; a first drive assembly is also provided inside the housing, and the first drive assembly is signal-connected to an intelligent system; a traction assembly is provided inside the rotating cylinder, and a limiting assembly is provided inside the fixed cylinder; a disc is fixedly connected to the rotating cylinder, and several wire-passing holes are provided on the disc, each wire-passing hole having a detection groove, and a detection block is slidably connected in each detection groove, with each detection block equipped with a pressure sensor. This invention, by designing a component capable of pre-paying wire to assist in pay-off, and combining it with a stranding force acquisition and analysis system, achieves control over pay-off tension and stranding force, improves the final conductivity of the conductor, and improves the overall quality of the produced cable.

The utility model discloses an automatic stranding device for a composite enameled wire, and relates to the technical field of enameled wire production. Comprising a pay-off assembly, a stranding assembly and a take-up assembly, a rotating disc is rotationally arranged in the pay-off assembly, and a plurality of pulley assemblies are evenly installed on one side of the rotating disc to compensate the tension state of a cable during stranding; the semicircular holes of the two wire stranding bottom plates in the wire stranding assembly form a circular hole, and a wire stranding cylinder is rotatably mounted in the hole; the take-up assembly is rotatably provided with a take-up wheel, and one side of the take-up wheel is provided with a cycloid mechanism for applying reciprocating transverse displacement to the stranded cable. A spring tensioning mechanism of the pulley assembly is adopted to achieve dynamic adjustment of cable tension, reciprocating motion of the cycloid rod is matched with rotation of the take-up wheel to achieve uniform winding of the cable, the pay-off / take-up wheel is rapidly replaced through the electromagnetic driver, and the replacement efficiency of the take-up wheel is remarkably improved.
