Steel Plate Uncoiler
1. Equipment Overview
The steel plate uncoiler is a mechanical device used to unwind coiled steel plates and feed them into subsequent processing equipment (such as leveling machines, shearing machines, etc.). It is widely used in industries such as steel processing, automotive manufacturing, and construction, serving as a key piece of equipment in metal sheet processing lines.
2. Main Components
Uncoiler Body: Includes the frame, driving device, and uncoiling rollers, which support and unwind the coil.
Expanding Mandrel: Secures the inner diameter of the coil through expansion, ensuring stable unwinding.
Hold-Down Device: Prevents the coil from loosening or bouncing, ensuring a smooth uncoiling process.
Straightening Device (Optional): Provides initial leveling of the coil, reducing the difficulty of subsequent processing.
Automatic Centering System: Ensures the coil remains centered during the unwinding process.
Tension Control System: Adjusts the coil tension to prevent material deformation or breakage.
Electrical Control System: Enables automated operation and monitoring of the equipment.
3. Working Principle
Loading: Place the steel coil onto the expanding mandrel of the uncoiler and secure the inner diameter using the expanding mechanism.
Uncoiling: Activate the driving device to rotate the mandrel, gradually unwinding the coil.
Centering and Leveling: The automatic centering system adjusts the coil position, and the straightening device provides initial material flattening.
Feeding: The unwound steel plate is conveyed via a roller table to subsequent processing equipment (such as a leveling machine or shearing machine).
4. Technical Parameters

Equipment Weight: Typically 2-10 tons (varies by model)
5. Equipment Features
High Automation: Equipped with automatic centering, tension control, and PLC control systems for easy operation.
Efficiency and Stability: Utilizes heavy-duty structures and high-precision components to ensure smooth and durable operation.
Strong Adaptability: Suitable for coils of varying thicknesses, widths, and materials.
Energy Saving and Environmental Protection: Optimized design reduces energy consumption, noise, and vibration.
Multi-Functionality: Can be integrated with leveling machines, shearing machines, and other equipment to form a complete processing line.
6. Application Fields
Steel Processing: Uncoiling and processing cold-rolled and hot-rolled steel coils.
Automotive Manufacturing: Uncoiling and pre-processing body panels and component materials.
Construction Industry: Uncoiling and shearing steel plates and profiles for construction.
Home Appliance Manufacturing: Uncoiling and processing materials for appliance housings and components.
Aerospace Industry: Uncoiling and processing high-precision metal sheets.
7. Selection Recommendations
Choose the appropriate model based on coil dimensions (outer diameter, inner diameter, width).
Select the power and uncoiling speed according to material thickness and processing requirements.
Consider compatibility with subsequent processing equipment (such as leveling machines and shearing machines).
Opt for highly automated, easy-to-operate, and maintainable equipment to improve production efficiency.
8. Maintenance and Care
Regularly inspect the expanding mandrel, hold-down device, and driving system for proper operation.
Keep the equipment clean to prevent dust and debris from entering critical components.
Lubricate moving parts regularly to ensure smooth operation.
Replace worn parts promptly to avoid affecting equipment performance.
