What is the function of rewinding machine

      Rewinding machine is a core equipment used in industrial production for high-precision secondary winding and finishing of coiled materials such as wire, strip, foil, and pipe. Its core function is to improve the quality of winding, achieve precise rewinding, and ensure subsequent processing and delivery.

1、 Core functions and roles

High precision tension control (core)

      Adopting a closed-loop tension system to monitor and stabilize tension in real time (with an error of up to ± 0.5N), preventing material stretching, deformation, fracture, or loosening.

      Adapt to different specifications from * * fine wire (φ 0.01mm) * * to thick cables, aluminum rods, etc., to meet demanding scenarios such as precision coils and medical catheters.

Intelligent regular wiring arrangement

      The servo driven cable system achieves uniform, tight, skip free, and non overlapping layer winding, with a flat end face (such as a "telescope" shaped defect rate reduced to extremely low).

      Improve the density and neatness of roll packaging, facilitating storage, transportation, and subsequent automated processing.

Accurate division and fixed length

      Electronic length/counting, precise slitting and rewinding according to set length, weight or number of turns, suitable for downstream small batch and multi specification requirements.

      Replacing manual sorting, efficiency has been improved by over 40%, and the defect rate has been reduced from 3% to below 0.5%.

Quality repair and re inspection

      Perform secondary rewinding repair on initial defects such as looseness, wrinkling, edge collapse, and defects to improve the one-time pass rate.

      Integrated online detection, marking and removing defective segments to ensure zero defects in the final product.

Adapt to downstream processes

      Provide standard, clean, and stable roll packaging to ensure smooth subsequent winding, weaving, printing, lamination, coating, and other processes, reducing material jamming and downtime.

Dataization and traceability

      Record parameters such as tension, speed, length, batch, etc., supporting production traceability and quality control.

2、 Typical application scenarios

      Wire and cable: finished rewinding, rewinding, and rolling of power/communication cables and automotive wiring harnesses.

      Precision wire: tungsten molybdenum wire, enameled wire, welding wire, medical catheter, micro coaxial cable.

      Electronic coils: precision winding of coils for motors, solenoid valves, and sensors.

      Metal/non-metal strips: rewinding and slitting of aluminum strips, copper foils, films, tapes, and composite materials.

3、 Summary of Core Values

      Quality: High tension and wiring accuracy, eliminating deformation, looseness, and defects, and improving product consistency.

      Efficiency: High speed, fully automated, reducing manual labor and rework, and improving production line utilization rate.

      Cost: Reduce waste rate, downtime losses, and delivery disputes, optimize TCO.

      Flexibility: Quick changeover, suitable for multiple varieties and small batch production.
