It ensures precise roll cutting, smooth operation, and minimal material waste, making it a valuable asset for enhancing production efficiency and product quality.
Key Features
- High Processing Speed: Operates at a variable speed range of 0–300 meters per minute, allowing flexible adjustment to match production demands and material characteristics.
- CNC Control System: Equipped with an advanced Computer Numerical Control (CNC) controllerfor precise operation, real-time monitoring, automatic fault diagnosis, and user-friendly interface. Enables accurate setting of slit width, tension control, and rewinding parameters.
- Hydraulic System Integration: Features a stable hydraulic systemfor automatic unwind and rewind shaft expansion/contraction, ensuring secure roll mounting and consistent tension control throughout the process.
- Precision Slitting Mechanism: Utilizes high-hardness, sharp-tipped circular rotary knives for clean, burr-free cuts. Knife positioning is adjustable to accommodate various slit widths with high accuracy.
- Fully Automated Operation: Automated loading, slitting, rewinding, and labeling processes reduce labor requirements and increase throughput.
- Tension Control System: Closed-loop tension control maintains consistent tension on both unwind and rewind stands, preventing paper stretching, tearing, or wrinkling.
- Durable Construction: Built with heavy-duty steel frame and precision components to ensure long-term stability and minimal vibration during high-speed operation.
- Safety and Compliance: Designed in accordance with international safety standards, featuring emergency stop functions, protective guards, and CE-compliant electrical systems.
