Automatic label rewinder with a 7inch diameter and 4inch width, 10level speed adjustment, core compatibility for 1.49 in, 1.57 in, and 3 in cores, and bidirectional rewinding for flexible operation. Speed sensing technology uses an intelligent adjustment rod and gravity selfsensing to prevent deviation, helping maintain printer compatibility and automatically stop rewinding when printing ceases. Sidemounted knob provides easy speed control from 0 to 100 RPM across 10 gears, enabling userfriendly operation and realtime monitoring during use. Selfadjusting pressure bar protects the print head by automatically rising and stopping rewinding when printer speed is too , preventing damage and extending equipment life. Specifications and features Reel size: 7inch diameter, 4inch width Speed control: 10level adjustment; 0–100 RPM Core size compatibility: 1.49 in, 1.57 in, 3 in Rewind action: bidirectional Speed sensing: intelligent adjustment rod with gravity selfsensing; automatic stop when printing stops Control interface: sidemounted knob for easy access and monitoring Printhead protection: selfadjusting pressure bar rises and stops rewinding if printer speed exceeds safe levels Practical use scenarios volume label production on compatible printers: With 10speed levels and bidirectional rewinding, it maintains consistent tension and alignment across long runs, reducing manual interventions. Mixedcore labeling operations: Core size compatibility (1.49 in, 1.57 in, 3 in) accommodates a range of label rolls without needing frequent equipment changes, streamlining setup. Variablespeed printing environments: The gravitybased speed sensing and automatic stop help prevent deviations and potential damage when printer speeds fluctuate, preserving print integrity and extending equipment life.
