Description

OLED photocuring drying equipment for printing machine

Technical Field

The utility model relates to an OLED photocuring drying equipment for printing machine.

Background

In recent years, the use of UV technology in the printing industry has increased dramatically for various reasons including environmental protection, energy saving, etc., including UV curable inks and UV curable drying technologies. And is not dissolved completely. Compared with the traditional thermal radiation curing, the UV curing has the advantages of high drying speed, good glossiness, water resistance, good wear resistance, very little pollutant emission and the like, but a high-pressure mercury lamp with the wavelength range of 240-420 nm is generally adopted as a drying light source of the traditional UV ink, the spectrum of the high-pressure mercury lamp is very wide, the ultraviolet spectrum wave band really playing an effective curing role only occupies a small part of the high-pressure mercury lamp, and a large part of the wave band is positioned in a visible light region and an infrared region, so that the generated heat is very high (the working temperature is 70-80 ℃), an air exhaust device needs to be additionally arranged, environmental noise is generated, and the printing stock is easily heated and deformed during drying, and subsequent processing is influenced.

The LED light source does not contain infrared spectrum in the spectrum, so the LED light source belongs to a cold light source. The light source adopts the light emitting diode, the wavelength is 360-420 nm, the light source belongs to an ultraviolet spectrum waveband with an effective curing effect, the energy utilization rate is high, the radiant heat is low (the working temperature is 30-35 ℃), the ink curing time can be greatly shortened, the energy is saved, the working temperature can be kept at 30-35 ℃, under the temperature condition, a printing stock is basically not influenced, and therefore, the LED light source is quite wide in printable materials. Meanwhile, compared with the traditional UV curing technology, ozone and heat are not generated, and the occupied positions of the dryer and peripheral equipment are small due to the fact that the module is small.

However, one disadvantage of LED light sources is that the electroluminescent characteristics of the diode material determine that the LED light sources have generally low luminous density and narrow emission wavelength range, and are almost monochromatic wavelength light sources, and the emission wavelength of common LEDs differs according to the chip materials used, and mainly has characteristic emission wavelengths of 365, 375, 385, 395 and 405 nm. However, the current LED light-curing inks are of various types, and the most effective absorption curing wavelengths corresponding to the LED light-curing inks are different from each other, so that it is a place where light-curing equipment needs to be improved to improve the light-curing efficiency through the light distribution design of the light source module in the face of different types of printing inks.

In addition, light is energy, and photons are absorbed by ink and converted into heat, so that the conversion efficiency of the LED light source is less than 100%, and a small amount of heat is still released, so that the effective heat dissipation of the light source module is a core issue of light source design for improving the radiation power density and ensuring the long life.
