Description

Label printing machine ultraviolet wave flat-convex cylindrical lens composite light source rapid curing device

Technical field:

The invention relates to an ultraviolet curing device, in particular to a rapid curing device for a compound light source of an ultraviolet wave flat-convex cylindrical lens for a label printing machine. Compared with a traditional ultraviolet curing device, the device is more energy-saving, environmentally friendly, fast and efficient, and can replace UV curing unit for existing label printing machines.

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, timely adjustment of the light source irradiation range and light source irradiation intensity according to the label printing width and label printing speed can further reduce the energy consumption of the UV LED curing device, improve system stability and control accuracy, and improve the UV curing effect.

3rd area source is by the neat multiple ultraviolet light-emitting diodes structures being welded on the 3rd piece of ceramic base light source board front Becoming, the back side of the 3rd piece of ceramic base light source board is pasted onto on the bottom surface of the 3rd rectangle water-filled radiator by heat-conducting glue, and the 3rd Ultraviolet light-emitting diodes on block ceramic base light source board is divided into the M group facet light source that length and width are identical, M group facet light source With M photoelectric tube align one by one along the equidistant word order of paper out opening, and respectively group facet light source by aligning The photoelectric tube of arrangement controls, and the ultraviolet light-emitting diodes in each group of facet light source is electrically coupled in series rear and light source controller Light source drive part divides electrical connection,

The top layer of label paper curing ink, on the paper of label paper, is entered by the directional light direct irradiation that the first area source sends Row solidification,

What the first ultraviolet wavelength piano convex cylindrical lens was parallel with the paper of label paper is arranged on the second rectangle water-filled radiator Underface, and the focal line f of the first ultraviolet wavelength piano convex cylindrical lens is positioned at lower end, face of label paper, second piece of pottery The front of base light source board is just to the first ultraviolet wavelength piano convex cylindrical lens so that each group on second piece of ceramic base light source board front The directional light that facet light source sends is radiated on the paper of label paper through the first ultraviolet wavelength piano convex cylindrical lens, at mark Sign the euphotic zone forming the multiplication of a branch of light intensity on the paper of paper, the shallow top layer of label paper curing ink solidified,

What the second ultraviolet wavelength piano convex cylindrical lens was parallel with the paper of label paper is arranged on the 3rd rectangle water-filled radiator Underface, and the focal line F of the second ultraviolet wavelength piano convex cylindrical lens is positioned on face of label paper, the 3rd piece of ceramic base The front of light source board is just to the second ultraviolet wavelength piano convex cylindrical lens so that each group on the 3rd piece of ceramic base light source board front is little The directional light that planar light source sends focuses on the paper of label paper, at label through the second ultraviolet wavelength piano convex cylindrical lens Form the wire high light of light intensity multiplication on the paper of paper, the deep layer of label paper curing ink solidified,

When the label paper of one fixed width through rectangular paper feed hole and paper out opening through the transmitting of mid portion photoelectric tube Time between pipe and reception pipe, the light that the transmitting tube of this part photoelectric tube sends is cut off by label paper can not arrive reception Pipe, this part photoelectric tube is off, and remaining photoelectric tube is in the conduction state, and the state of each photoelectric tube is sent to The illumination width detection part of light source controller, on the first area source, the second area source and the 3rd area source be in disconnection shape Each group facet light source of the photoelectric tube alignment of state is divided by the light source drive part of light source controller and adds electroluminescence, remaining The not powered luminescence of facet light source of each group,

Velocity sensor is arranged in lower box, and velocity sensor is positioned at the lower end in rectangular paper feed hole, velocity pick-up Device detects part with the intensity of illumination of light source controller and electrically connects, and label paper is close to by velocity sensor, when label paper is at mark Sign under the drive of printer, during with speed v through rectangular paper feed hole and rectangular paper out opening, the mobile speed of label paper Degree signal Negotiation speed sensor is sent to the intensity of illumination detection part of light source controller, light source controller pass according to speed The rate signal that sensor detects adjusts on the first area source, the second area source and the 3rd area source each group and adds the little flat of electroluminescence The intensity of illumination of area source.
