◦ Support dual-mode positioning of QR code/color code to meet the slitting needs of complex foil stamping patterns.

3. Temperature field optimization technology of hot pressing module

◦ The design of partitioned heating plate (8-12 independent temperature zones) is adopted, and the temperature difference is controlled at ±1.5°C to avoid the warping problem caused by uneven heating of the gold leaf.

◦ Nano-scale ceramic coating hot stamping roller, thermal conductivity increased by 40%, service life of more than 2 million times.

4. Adaptive slitting algorithm

◦ Automatically calculate the optimal tool pressure (0-50N adjustable) based on material thickness, hardness and other parameters, and the diamond tool life management system can predict the timing of tool change.

2. Disruptive innovation points

• Zero Waste Start-up Technology: By pre-storing 100 sets of material parameters and automatically matching historical data during rewinding, the start-up scrap rate is reduced from 3% to less than 0.2%.

• Blockchain traceability system: Each slitting unit is implanted with an RFID chip to record production data (temperature/pressure/speed) throughout the process to achieve anti-counterfeiting traceability of luxury packaging.

• Energy recovery design: The braking energy is fed back to the grid, and the power consumption of the whole machine is reduced by 25% compared with the traditional model.

3. Industry application scenarios

1. High-end packaging field

◦ Tobacco and alcohol packaging: Achieve 0.1mm ultra-fine line hot stamping to meet the needs of anti-counterfeiting trademark slitting.
