I. Basic Structure and Components
1. Uncoiler**
Function: Supports and unwinds raw material coils, providing stable unwinding tension.
Types: May include automatic centering devices to adapt to different coil widths.
2. Guiding and Leveling System
Guide Rolls**: Ensure material enters the cutting zone in a straight line.
Leveling Rolls**: Eliminate bends or waves in the coil to improve cutting precision.
3. Cutting Mechanism (Core Component)
Rotary Blade Cutting**: Uses rotating upper and lower circular blades for high-speed continuous slitting (common for thin metal sheets).
Guillotine Blade Cutting**: Combines fixed and moving blades for thicker materials (e.g., rubber, thick plastics).
Laser/Ultrasonic Cutting**: Non-contact cutting for high-precision or specialty materials (e.g., electronic films).
4. Slitting and Rewinding System
Function: Rewinds slit narrow strips into independent smaller coils.
Types: Multi-station rewind shafts with synchronized or independent tension control.
5. Control System
Automation: Adjusts slitting width, speed, and tension via PLC or CNC systems.
Human-Machine Interface (HMI): Touchscreen operation with real-time monitoring.
II. Working Principle
1. Unwinding: Raw material is unwound, leveled, and fed into the cutting zone.
2. Slitting: The cutting mechanism longitudinally divides the material into narrow strips based on preset widths.
3.Rewinding: Slit strips are rewound into individual coils.
III. Main Classifications
1. By Material Type
Metal slitters (e.g., stainless steel strips, copper foil).
Non-metal slitters (e.g., plastic films, paper, composites).
2. By Automation Level
Manual: Manual blade adjustment for small-batch production.
Fully Automated: Automatic blade change and online inspection for large-scale processing.
3. By Cutting Technology
Mechanical (rotary/guillotine blades).
Laser (wear-free, high precision).
- Hydraulic (for ultra-thick materials).
