High-speed UV light curing control device for printing press

Abstract

The invention relates to light curing equipment and particularly relates to a high-speed UV (ultraviolet) light curing control device which comprises a UV lamp provided with a spotlight cover, a fan, a UV electronic power supply provided with a fault detection signal wire, a controller and a frequency converter, wherein the output end of the UV electronic power supply is connected with a UV lamp, and the fault detection signal wire of the UV electronic power supply is connected with the controller; the illumination region of the UV lamp is provided with a temperature sensor which is electrically connected with the controller; the output end of the frequency converter is connected with the fan; and the input end of the controller is at least provided with a start button and a power-reducing button, and the output end of the controller is respectively connected with the UV electronic power supply and the control end of the frequency converter. The novel device provided by the invention can be used for realizing the automation of the temperature control and on-off control on a light curing device, thus the printing quality and the printing efficiency are further ensured.

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...

Problems solved by technology

Furthermore, the power of the lamp needs to be increased step by step during the start-up process. Full power conduction in the cold state will cause excessive current impact and damage the UV lamp.

[0003] This shows that in the structure and use of above-mentioned existing UV curing machine, obviously still have inconvenience and defective, and urgently need to be further improved
