High-performance UVLED line light source curing system, the system mainly includes a controller, UVLED irradiation head and connecting wires. The UVLED irradiation head is integrated with imported high-intensity UV LEDs, using forced air cooling, and the effective curing area is 500*20mm adjustable. It supports external signal input and triggering, and can be equipped with semi-automatic or fully automatic production lines. LEDs of different wavelengths and powers cure different UV glues, UV inks, UV varnishes, UV paints, etc.
