Description

Double reflection UV multi-stage fast curing device for label printing machine

Technical field:

The invention relates to an ultraviolet curing device, especially a double-reflection ultraviolet multi-stage rapid curing device for a label printing machine. Compared with the traditional ultraviolet curing device, the device is more energy-saving, environmentally friendly, fast and efficient, and can replace the existing label UV curing unit for printing presses.

Background technique:

Curing refers to the process in which inks, coatings, adhesives, sealants, etc. are transformed from a liquid state to a solid state. Ultraviolet curing is a method that uses ultraviolet rays and photoinitiators added to inks, coatings, and sealants to produce photochemical reactions to achieve rapid curing.

The rapid curing of ink in label printing is an important part of the label printing process. However, in the label printing industry, most of the point and line light sources composed of high-pressure mercury lamps and metal halide lamps are used to achieve ultraviolet curing. Both high-pressure mercury lamps and metal halide lamps have consumption Due to the characteristics of high energy, heavy metal pollutants and short life, high-pressure mercury lamps and metal halide lamps need to be replaced frequently during use. Therefore, the use of high-pressure mercury lamps and metal halide lamps to achieve ultraviolet curing will result in high cost and high energy consumption. It will also cause heavy metal environmental pollution , neither energy saving nor environmental protection,

In recent years, people have introduced ultraviolet light-emitting diodes into the field of ultraviolet curing, and developed ultraviolet light-emitting diode curing devices.

Compared with the high-pressure mercury lamp and metal halide lamp UV curing method, the UV light-emitting diode curing method can greatly reduce energy consumption, no ozone and volatile organic substance emissions are generated during the curing process, the light source has a long service life, and no preheating and cooling are required. It is especially beneficial for label printing and printing of heat-sensitive printing materials, but the light source irradiation range and light source irradiation intensity of the existing UV LED curing device are fixed, and the light source cannot be adjusted in time according to the width of the printed matter and the printing speed. The irradiation range and light source irradiation intensity, large energy consumption, low system stability and control accuracy, poor UV curing effect,

Therefore, according to the label printing width and label printing speed, timely adjust the light source irradiation range and light source irradiation intensity, and adopt multiple ultraviolet strong light belts composed of multi-stage double reflection, which can further reduce the energy consumption of the ultraviolet light-emitting diode curing device and improve the system efficiency. Stability and control accuracy, and greatly increase the speed of UV curing,
