Uncoiler and Infeed System
Advantages: Ensures stable entry of the strip, maintains tension balance, reduces initial surface defects and edge skip, and improves subsequent cutting consistency.
Key Points: Soft-start / adaptive tension, centering and alignment, quick loading/unloading mechanism, capability to handle coil diameter and thickness ranges.
Tension Control System
Advantages: Uniform tension along the entire line, reduces thin-plate distortion and edge burrs, enhances cutting stability and product straightness.
Key Points: Closed-loop servo drive, tension sensors (sensor types and placement), online tension adjustment algorithm, redundancy and fault-tolerance design.
Knife System (Shearing Knife, Knife Holder, Knife Change Mechanism)
Advantages: High shear accuracy, low burr, clean edges; supports fast knife changes for different cut widths and materials.
Key Points: Knife material and coating, blade gap / drop-point control, knife replacement methods (manual / semi-automatic / automatic), knife wear monitoring.
Auxiliary Edge and Positioning Mechanisms (Back-up Rolls, Positioning Rolls, Knife Drop/Lift Mechanisms)
Advantages: Improves edge straightness and stability, reduces edge warping and defects, ensures edge consistency.
Key Points: Uniform back pressure / support, timing accuracy of knife drop and lift, edge detection and self-diagnosis capability.
Coiling and Uncoiling System
Advantages: High-quality winding, matched tension, minimizes wrinkles and edge offset during winding, facilitates downstream processing.
Key Points: Handling varying coil diameters, coil core alignment, winding tension control, quick reel changes.
Drive & Control System (Servo Drives, Inverters, PLC, HMI)
Advantages: High positioning accuracy, fast response and stable operation; easy integration with automation and data collection.
Key Points: Robustness of control algorithms, system redundancy, interface with MES/ERP.
Online Inspection and Quality Control System
Advantages: Real-time monitoring of edge trim, edge quality, width uniformity, and tension status; reduces defects and enables traceability.
Key Points: Sensor coverage and accuracy, data communication interfaces, alarms and self-diagnostic capability.
Lubrication and Cooling System
Advantages: Reduces tool wear, controls thermal expansion, improves tool life and cut edge quality.
Key Points: Lubricant/coolant selection, nozzle layout, collection and reuse design.
