Uncoiler
Core Advantages of Uncoiling Equipment
High-Efficiency Production
Continuous automatic uncoiling and feeding significantly increase production line speed and reduce downtime.
Quick coil change capability (e.g., hydraulic expanding shafts) ensures efficient operation.
Precision Control
Tension control system (mechanical/electronic) prevents material stretching, deformation, or wrinkling, ensuring flatness.
Synchronized operation with downstream equipment (levelers, stamping presses) maintains production stability.
Wide Adaptability
Handles various specifications of metal coils and different coil weights.
Adjustable mandrels or expandable sleeves accommodate different inner diameters (e.g., Φ508mm/Φ610mm).
Durability & Safety
Heavy-duty steel structure for high-load industrial environments, ensuring long service life.
Equipped with emergency stop buttons, protective covers, overload protection, and complies with CE/OSHA standards.
Smart Integration
Supports PLC automation and interfaces with MES systems for data monitoring and remote operation.
Optional robotic arm for automatic loading, enabling unmanned production lines.
Energy Saving & Cost Reduction
Reduces manual intervention and material waste (e.g., edge-trimming loss minimized by alignment systems).
Modular design simplifies maintenance, and key components (bearings, hydraulic units) are easy to replace.
Industry-Specific Advantages
Metal Processing: Anti-scratch rubber rollers, heavy-duty uncoiling for thick plates (e.g., steel coils above 20mm).

Technical Details of Uncoiler Equipment
1. Overview
An uncoiler (also called an unwinder) is an automated device used to unwind coiled materials such as metal sheets, films, and paper. It is widely used in metal processing, packaging, printing, and new energy industries. Core functions include automatic unwinding, tension control, edge alignment, and material feeding.
2. Types of Uncoilers
| Type | Features | Applications |
|---|---|---|
| Heavy-Duty Uncoiler | High-load design for thick steel plates (20mm+) and heavy coils (10+ tons) | Automotive, shipbuilding, steel structure production |
| Light-Duty Uncoiler | Compact structure for aluminum coils, copper foil, thin stainless steel (0.1-3mm) | Electronics, batteries, precision metalworking |
| Double-Head Uncoiler | Dual-station design for non-stop coil change, improving production efficiency | High-speed continuous stamping, automated lines |
| Hydraulic Uncoiler | Hydraulic expanding shaft with automatic centering, compatible with various inner diameters (Φ450-Φ800mm) | Mixed production of different coil specs |
