1. Mechanical structure optimization
• High rigidity frame and bearing system
The frame is made of high-strength alloy steel or composite materials, with precision bearings (such as ceramic bearings) to ensure that the vibration amplitude < 0.05mm during high-speed operation, avoiding material deviation or uneven sectional surfaces.
• Dynamic balance spindle
The spindle speed should reach 8000-12000 RPM, and the dynamic balance class G1.0 or lower to reduce the wear caused by centrifugal force.
• Quick tool change system
Hydraulic or pneumatic tool holders with automatic tool setting devices reduce downtime by < 30 seconds.
2. Drive and control system
• Servo motor + direct drive technology
It adopts a high-torque servo motor (such as Siemens S210 series) with a direct drive (gearless drive), with a response time of < 1ms and a speed fluctuation of <± 0.1%.
• Multi-axis synchronous control
Through PLC (such as Beckhoff CX series) and encoder feedback, the synchronization error of unwinding, traction and rewinding is < 0.01% to avoid tension fluctuations.
• Adaptive tension control
Magnetic particle brake + ultrasonic tension sensor, dynamically adjust the tension (range 2-50N) to ensure that the material does not have tensile deformation at high speed.
3. Cutting system upgrade
• High hardness tools
Diamond-coated or carbide inserts (hardness ≥ 90 HRA) with a lifespan of more than 2,000 km.
• Laser or ultrasonic cutting (optional)
Non-contact cutting is suitable for thin film materials, with a cutting accuracy of ± 0.1mm and no burrs.
4. Intelligence and monitoring
• In-line defect detection
High-speed industrial camera (5000fps) + AI algorithm to identify defects such as cracked edges and stains in real time, and the scrap rate < 0.1%.
• Predictive maintenance
Vibration sensor + temperature monitoring, early warning of bearing or tool failure, equipment utilization increased to 95%.
5. Material adaptability
• Wide width compatibility
It can handle materials with a width of 1000-2500mm and a thickness range of 5-500μm (e.g. PET, BOPP, aluminum foil).
• Static elimination
The ion air rod eliminates static electricity generated by high-speed slitting (surface resistance ≤ 10^6Ω) and avoids material sticking.
Quantify production efficiency improvement
• Theoretical capacity calculation:
300m/min × 60min × 0.95 (utilization) = 17,100 m/h, which is 50% higher than the 200m/min model.
• Material change efficiency: The automatic material receiving system compresses the wind change time to <2 minutes, and the comprehensive OEE (equipment comprehensive efficiency) can reach more than 85%.
Challenges and responses
• Thermal management: Requires a liquid cooling system to control the blade temperature < 80°C.
• Noise control: acoustic enclosure + shock absorbing base, noise ≤ 75dB.
Through the integration of the above technologies, the slitting machine can still ensure a slitting accuracy of ±0.05mm at a speed of 300m/min, while reducing energy consumption by 15%-20%, achieving a balance between high speed and high precision.
