In Kunshan Youyuan Sheng Machinery Co., Ltd., we specialize in the production of paper cutting machines, such as the flat knife paper cutter. The Flat Knife Cutting is an essential way used in the paper industry to cut paper into smaller sizes.
1. Core Flat Knife Cutting Technology
Kunshan Youyuan Sheng’s flat knife cutting system employs an advanced center-positioned horizontal blade mechanism that delivers:
- ≤0.05mm cutting tolerance (ISO 9001-certified)
- 20-100m/min adjustable cutting speed
- 0.1-10mm material thickness capacity
2. Middle Flat Knife Cutting Method
2.1 Technical Implementation
- Blade Positioning:
- Centered blade alignment (±0.02mm runout)
- 45° hardened steel blade (HRC 60-62)
- Motion Control:
- AC servo drive (0.01mm positioning accuracy)
- Linear guide rails (≤5μm vibration amplitude)
2.2 Performance Advantages
| Feature | Benefit |
|---|---|
| Symmetrical force distribution | Eliminates material deformation |
| Continuous horizontal motion | Prevents fiber tear (Ra ≤3.2μm) |
| Automatic gap adjustment | Maintains precision across thickness changes |
3. Machine Architecture
3.1 Cutting System Components
- Dual-blade stabilization: Tungsten carbide guides
- Dynamic pressure control: 50-500N adjustable
- Real-time monitoring: Laser thickness sensors
3.2 Control System
- HMI Features:
- 10″ touchscreen with 50+ preset programs
- Automatic blade wear compensation
- Production data logging (CSV export)
4. Material Compatibility of Flat Knife Cutting
| Paper Type | Optimal Speed | Special Considerations |
|---|---|---|
| Tissue | 80-100m/min | Low pressure setting (50N) |
| Kraft | 40-60m/min | High blade angle (50°) |
| Laminated | 20-40m/min | Static elimination required |
| Carbonless | 60-80m/min | Precision registration critical |
5. Quality Assurance Measures
- Pre-cut calibration: Auto-leveling system
- Post-cut inspection: 5MP vision system checks edge quality
- Blade maintenance: Automatic sharpening every 5,000 cycles
6. Operational Efficiency Metrics
- Changeover time: <3 minutes (tool-less adjustment)
- Waste reduction: ≤1.5% material loss
- Energy consumption: 3.8kW at full capacity
7. Industry Applications
- Security paper: Guillotine-cut serialized sheets
- Flexible packaging: Kiss-cutting laminated films
- Printing: High-precision sheet-fed division
8. Comparative Advantage
| Parameter | Conventional Cutting | Youyuan Sheng Flat Knife |
|---|---|---|
| Tolerance | ±0.2mm | ±0.05mm |
| Speed | 40m/min max | 100m/min max |
| Blade Life | 3,000 cuts | 10,000+ cuts |
9. Support Services
