Description

technical field [0001] The invention relates to a photocuring device, in particular to a high-speed UV photocuring control device for a printing machine. Background technique [0002] At present, the printing and ink of the printing machine are cured by UV light curing equipment. UV light curing equipment is the key equipment to ensure the printing quality. A typical UV light curing equipment is composed of a light source system, a cooling system and a control system. The light source system includes UV Lamp, lampshade, UV electronic power supply (or trigger, ballast); most of the cooling systems are air-cooled. If the air volume is too small and the cooling is insufficient, the temperature of the UV lamp will be too high and the life of the lamp will be shortened. It also makes the cured product wrinkle, and the quality is difficult to guarantee; if the air volume is too large and the cooling is excessive, the temperature of the UV lamp will be too low, the UV lamp cannot w...
