uncoiling machine

Product Overview

• Function: Unwinding at the front end of the strip processing line to achieve stable unwinding, high-precision tension control, and smooth feeding, with seamless integration to downstream equipment (e.g., cutting, coating, straightening, etc.).

• Applicable Materials: Steel, aluminum, and other metal strips, widely used in automotive, home appliances, packaging, and furnishings.

• Basic Structure: Reels/unwinding drum, tension sensing with closed-loop control, clamping/unwinding mechanisms, drive unit, protective cover and safety interlocks, control cabinet and HMI.

Applicable Range

• Coil diameter range (inner/outer options): commonly Ø450–Ø1500 mm (model-dependent)

• Coil width: about 80–2000 mm (depends on model)

• Thickness range: about 0.2–6.0 mm

• Maximum tension and line speed: varies by model; typical range 0–tens of kN for tension and up to about 150 m/min for line speed

• Material compatibility: steels, magnesium alloys, aluminum and other metals

Key Features and Benefits

• Stable tension closed-loop control: ensures flat, uniform tension during unwinding and reduces coil deformation

• High-speed, smooth feeding: increases line speed and reduces downtime caused by feeding instability

• Wide applicability: supports a range of coil diameters, widths, thicknesses, and materials

• Automation and intelligence: servo drive, tension sensing, data collection, remote diagnostics, predictive maintenance

• Safety and user-friendliness: emergency stop, overload protection, anti-pinch features, and an easy-to-use HMI

• Seamless integration with downstream processes: easy interfacing with cutting, coating, straightening, and other equipment to boost line throughput

• Low maintenance, modular design: easy-to-replace consumables with standardized modules for expansion

• Energy efficiency and cost benefits: servo-driven/inverter-driven design enhances efficiency and reduces long-term operating costs
