1. Introduction
As the core material of thermal transfer printing, the slitting quality of ribbon directly affects the printing effect and performance. Traditional ribbon production adopts decentralized process, which has problems such as low efficiency, large loss and unstable quality. The integrated ribbon slitting machine integrates slitting, testing, packaging and other processes, providing a hardware foundation for process optimization.
2. Analysis of traditional production processes
2.1 Main processes
• Raw material unwinding→ slitting→ quality inspection→ rewinding→ packaging
• Each process is equipped with independent equipment, which needs to be handled and repositioned multiple times
2.2 Main Issues
1. The process connection efficiency is low, accounting for 25-30% of the whole production time.
2. Increased risk of surface scratches due to multiple handlings
3. The matching degree between the slitting parameters and the packaging specifications is poor
4. The quality inspection is lagging behind, and the defective products are found late
3. Integrated equipment optimization scheme
3.1 Optimization of mechanical structure
• Adopt a "one" layout to reduce the transmission distance
• Integrated tension control system, slitting tension ± 0.5N
• Automatic deviation correction device, the deviation is controlled within ±0.2mm
3.2 Electrical control system upgrade
• PLC+touch screen control, preset 20 kinds of product parameters
• On-line thickness measurement system, real-time monitoring of thickness deviation
• Automatic counting and length control with an accuracy of ±0.1m
4. Process optimization
4.1 Optimization of slitting process parameters
parameter | Before optimization | After optimization |
Slitting speed | 80m/min | 120m/min |
Slitting tension | 15N±2N | 18N±0.5N |
Tool life | 8 hours | 24 hours |
4.2 On-line detection system
• Integrated CCD visual inspection, detection speed of 150 frames/second
• Defect identification accuracy≥ 99.8%
• Automatically flag defective locations for easy follow-up processing
5. Packaging process improvement
5.1 Automatic packaging system
• Automatic cutting and winding to reduce manual intervention
• Intelligent packaging material matching system
• Nitrogen replacement device for moisture-proof packaging
5.2 Packaging Quality Control
1. Appearance inspection: no scratches, no wrinkles
2. Dimensional accuracy: width deviation≤±0.1mm
3. Core concentricity: ≤0.05mm
4. Packaging tightness: helium leak detection rate< 1×10⁻⁶Pa·m³/s
6. Implementation Effects
After 3 months of trial operation and adjustment, the main indicators have improved as follows:
• Productivity: 35% increase
• Material loss: from 5.2% to 4.1%
• Energy consumption: 18% reduction
• Packaging pass rate: increased from 97.3% to 99.5%
• Labor costs: 40% reduction
7. Conclusion
The process optimization practice of the integrated ribbon slitting machine shows that the production efficiency and product quality can be significantly improved through equipment integration, process parameter optimization and intelligent transformation. In the future, we can further explore the application of big data analysis and artificial intelligence technology in predictive maintenance and adaptive control to achieve a higher level of intelligent manufacturing.
