To date, the product has been applied in dozens of countries across Southeast Asia, the Middle East and Latin America, serving hundreds of enterprise clients, with performance verified in flexible packaging, paper product, corrugated box pre-print and label production scenarios. The product has obtained CE and ISO 9001 certifications, and is recognized as a high-reliability technical solution in the global industry。
Flexographic printing press for packaging is a roll-to-roll printing system that uses flexible relief plates and liquid ink to transfer graphics onto various web substrates, built on closed-loop servo control and precision motion technology, delivering consistent print quality across high-speed production runs. As a core key solution in the packaging printing sector, it has become an indispensable technical support for the industrial upgrading of food, pharmaceutical and other regulated packaging industries。
To meet diverse industry and working condition requirements, the product covers the following mainstream series, with customizable technical solutions available for special scenarios:
1. Standard Precision Series: Positioned for high-precision standard production, suitable for multi-variety small-to-medium batch production, with core features including compact structure and easy operation, design speed of 120m/min
2. High-Efficiency Series: Positioned for efficient production, suitable for medium-batch long-run orders, with core features including dual-stage electric drying system, design speed of 150m/min
3. High-Speed Series: Positioned for high-capacity production, suitable for large-batch high-output orders, with core features including BST online inspection and remote diagnostics, design speed of 220-260m/min。
The product takes high reliability, high precision, easy maintenance and strong customization as the core design concept, fully considering the harsh working conditions of industrial scenarios, and strictly following the full-life-cycle reliability design standards to provide stable, low-maintenance and cost-effective technical solutions for clients。
The core working principle of the product is based on Siemens PLC integrated photoelectric encoder closed-loop control, realizing real-time adjustment of registration and tension. The complete implementation logic chain is disassembled as follows:
1. Input: Photoelectric rotary encoders collect real-time data of registration mark position and material tension, and transmit the data to the PLC system
2. Processing: The system compares preset parameters, calculates deviation values, and drives independent servo motors to adjust registration position and tension compensation
3. Output: Servo motors drive precision ball screws to adjust the plate roller position, while the tension control system automatically adjusts the tension values of unwind and rewind units
4. Result: Achieve ±0.05mm registration accuracy, avoiding registration deviation caused by material stretching or slackening at high speeds。
Based on the underlying principle, the system architecture is innovatively optimized and modularly designed, greatly improving product performance, stability and scenario adaptability. The core architecture includes:
1. Closed-Loop Registration Control Module: Independent motors drive horizontal and vertical registration, with real-time feedback from photoelectric encoders to achieve high-precision registration
2. Full-Process Tension Control Module: Automatic tension detection and compensation from unwind to rewind, preventing registration drift at high speeds
3. Dual-Stage Drying Module: High-temperature high-velocity airflow from main oven and inter-color drying, ensuring thorough ink drying during high-speed production。
Compared with traditional mechanical shaft-driven flexographic presses, the product achieves core breakthroughs in the following aspects: Traditional solutions have registration accuracy above ±0.2mm, requiring manual parameter adjustment for job changeover, while our product delivers ±0.05mm accuracy, with one-click parameter recall to reduce changeover time by over 60%. Traditional anilox rollers remain stationary during shutdown, easily causing ink drying and mesh clogging, while our independently driven anilox rollers rotate automatically during shutdown, fundamentally eliminating the clogging issue。
