Description

UV ink-jet printer LED ultraviolet source delay exposure device
Technical field
The present invention relates to the device of ink-jet printer ultra-violet curing ink-jet ink, particularly a kind of UV ink-jet printer LED ultraviolet source delay exposure device.
Technical background
Existing ultra-violet curing (UV) ink-jet ink is comprised of oligomer, activated monomer, light trigger, colouring agent and additive usually, contains hardly and seldom contain the volatile solvent composition.For reducing the viscosity of ink main component, to meet the parameter request of piezoelectricity printing head, normally add the way realization that low viscous activated monomer dilutes by adopting.Activated monomer itself participates in photocuring reaction, the UV ink passes through the printing head spray printing on print media, almost be exposed immediately curing, its main component nearly all participates in photocuring reaction, so almost need not the solvent evaporates process, even contain a small amount of volatile solvent that carries from raw material, also can in course of injection, be evaporated, thereby so that surface of print media adjacent to one another ink dot seldom interpenetrate, disperse so that surface of print media forms clearly literal and pattern.This printing type characteristics also make it simultaneous adaptation in the printing of the print media on numerous nonabsorbables surfaces such as glass, ceramic tile, have the characteristics such as environmental friendliness, finished product be rapid.
Be equipped with mutually with above-mentioned feature, existing UV ink-jet printer ultraviolet source module is taked and the ink jet printing head mechanical connection, form the combination of light source and printing head, the mode of perhaps closing on very much apart from printing head, pressure is moved with shower nozzle or is matched and move with the printing head rhythmic movement according to certain rules, almost at the ink dot spray printing in surface of print media, realize ink dot irradiation curing, avoid because the ink droplet of spray printing on print media in time do not solidify from ink jet printing head, generation interpenetrates, disperse, and so that the printing character pattern thickens, being exceedingly fast simultaneously forms the printing finished product.
This UV inkjet printing mode has environmental friendliness, production efficiency height, is suitable for the advantages such as print media is many.But this kind UV Exposure mode is not suitable for some uses of UV ink that contain volatile solvent, the specific use of solvent evaporates process need to be arranged.Such as water-based UV ink, Weak solvent type UV ink.This two classes ink, the main component of its dilution ink be water and other environmentally friendly solvents, itself can not participate in photocuring reaction these compositions, if any the existence of these compositions, tends to affect solidification effect, end product quality in the Light Curing.So, after being printed shower nozzle when this class UV ink and being ejected into surface of print media, the volatilization process that solvent need to be arranged, and this kind solvent is when being used for a large amount of nonabsorbable surface of print media, all be difficult in the utmost point fully volatilization in the short time, so that print quality is difficult to acquisition assurance, of low quality, thereby limited the application of this class ink.
Summary of the invention
The invention provides a kind of UV ink-jet printer LED ultraviolet source delay exposure device, this device is suitable for the UV ink-jet printer to be used and to contain volatile solvent UV ink and carry out inkjet printing, and purpose is to improve and improve its print quality.
Described UV ink-jet printer LED ultraviolet source delay exposure device comprises printing head, LED ultraviolet source, be used for supporting the slide rail of printing head and LED ultraviolet source, it is characterized in that: described delay exposure device also comprises the heater for the heating print media, heater is arranged on front or the back side of printer loading of living in table top in print media plane between printing head and the LED ultraviolet source, and heater is hair-dryer or electricity heating device; Described delay exposure device so that the ink spray printing behind surface of print media, solidified by the LED ultraviolet source again after heater via heating makes solvent evaporates.
Heater is provided with control device, can control heating-up temperature, to guarantee being transmitted to the temperature of surface of print media at 10～60 ℃.
Terminal or further prolongation place in the printout heating, install the LED ultraviolet source additional, the LED ultraviolet source has the light source slide rail that is independent of printing head, the LED ultraviolet source is reciprocating by the light source slide rail, its motion is substantially parallel with inkjet printer head direction of motion Y-axis, its reciprocating speed is regulated according to UV ink cured effect by control device, on the light source slide rail on LED ultraviolet source both sides, be provided with to move back and forth the stop of position and distance according to print media breadth width adjusting LED ultraviolet source.In addition, the LED ultraviolet source that the present invention is installed additional, by the 3rd control device the electric current that is input to light source is limited, and by the assistance of stop LED ultraviolet source reciprocating direction, speed on the light source slide rail are carried out conversion, and by this control device, make the LED ultraviolet source arrive at the stop place along the light source slide rail and automatically turn back, the LED ultraviolet source can be added and subtracted along the speed that the light source slide rail moves.
Adopting the LED ultraviolet source, is because its miniaturization and, simplification, high energy efficiency more.
Between LED ultraviolet source and ink jet printing head, can install hair-dryer additional, further volatilize in order to solvent, it is dry to accelerate the surface of print media ink dot.This hair-dryer wind regime can be the hot blast of natural wind or uniform temperature temperature control.
To installing the hair-dryer of blowing hot-air additional, be provided with upper controller or claim the wind-warm syndrome control device, by this control device, to the hot blast stopped heating above 60 ℃.
The ultraviolet irradiation amount that print media is shone: 200～1500mJ/cm2, LED ultraviolet wavelength are 365-410nm.
The present invention is directed to and use the UV ink-jet printer that is added with volatile solvent UV ink-jet ink to propose, so that this type of ink spray printing is behind surface of print media, the process that one solvent evaporates is arranged, can not solidify at once, install heating apparatus additional or install at an upper portion thereof hair-dryer additional in ink-jet printer objective table bottom, perhaps carry out according to this assembled arrangement, make print media before being input to apparatus for feeding and UV ink spray printing on surface of print media and a segment distance after this, print media all can obtain certain heat from objective table, keep certain temperature, be beneficial to the volatilization of solvent, thereby improve print quality.
