Technical Principle

The machine operates on a multi-roller straightening system combined with hydraulic slitting and cut-to-length mechanisms:

1.Multi-Roller Straightening

The rollers are precision machined and hard-chrome coated to resist wear and maintain flatness over time.

Roll spacing and pressure can be adjusted according to material thickness and mechanical properties.

The system corrects longitudinal and transverse deformation by applying controlled bending moments across the sheet width.

2.Hydraulic Cutting & Slitting

Hydraulic shear provides clean, burr-free edges.

Slitting knives are hardened steel, designed for high-speed, continuous operation.

Optional embossing rollers can create anti-slip patterns for construction panels.

3.PLC & HMI Control System

A PLC system with HMI interface allows precise setting of batch length, sheet quantity, and slitting width.

Real-time monitoring ensures consistent output quality and minimizes operator intervention.

Automatic fault detection and alarm systems protect the machine and reduce downtime.

Structural & Mechanical Design

Frame: Heavy-duty welded steel structure minimizes vibration and deformation.

Drive System: High-torque gearbox and chain-drive system ensures smooth transmission and continuous operation.

Rollers: 8–14 rolls per section, hardened and precision-ground for consistent leveling.

Material Handling: Designed for coils up to 5 tons, optional auto-decoiler and stacker modules for continuous production.

Industrial Applications

Steel Structure Fabrication: Roof panels, wall panels, floor decks requiring precise flatness.

Sheet Metal Service Centers: Coil flattening and cut-to-length for resale or contract fabrication.

Industrial Equipment Manufacturing: Cabinet enclosures, machine housings, appliance panels.

Automotive & Appliance Production: High-precision sheet metal components.

Prefabricated Buildings: Panels for large-scale construction projects.

Engineering Advantages

1.Precision & Flatness: Advanced roller design ensures minimal residual stress and perfect flatness.

2.Flexibility: Adjustable rollers and slitting modules accommodate multiple sheet widths and thicknesses.

3.Automation & Efficiency: PLC-controlled operations reduce labor, improve accuracy, and increase throughput.

4.Durability: Heavy-duty components designed for continuous industrial use.

5.Energy Efficiency: Optimized hydraulic and electrical systems reduce operational costs.

6.Maintenance Friendly: Modular design allows quick replacement of wear parts.
