automatic inspection rewinding machine

The automatic inspection rewinding machine parameters as follows    Max rewind diameter Φ800mm Max unwind diameter Φ800mm Max speed 500M/min（according the material） Max width of material 1300mm Rewind core diameter Φ76mm, Φ152mm Unwind core diameter Φ76mm, Φ152mm Tolerance  ±0.3mm The machine weight 4000kg The voltage AC380V  50HZ The total power 21KW   This inspection rewinder adopts hydraulic lifting system, equipped with shaftless unwinding and shaftless rewinding for moving and fixing the web roll. It can run forward and reverse from unwind to rewind for inspection.    The machine is driven and controlled by 3 servo motor, with tension sensor installed on both the unwinding and rewinding unit to ensure stable and constant tension control. It is also equipped with a pneumatic pressing roll for smooth and tight rewinding, and the whole machine is controlled and monitored via an human-machine interface (HMI), which clearly displays real-time operating par…
