Abstract
The invention relates to a nozzle applied to ink jet, and especially relates to the module combination type ultra wide nozzle which is applied to one-way print of the whole ink jet medium width and a jet printing method thereof. The nozzle is provided with a support frame which exceeds the jet printing medium width. A number of nozzle modules are arranged on the support frame. All modules are in zigzag arrangement. Each module is provided with a certain number of spray nozzle arrays. The projection intervals of the spray nozzles of all modules of the nozzle are completely consistent in the movement direction of the nozzle relative to a medium and the projection width exceeds the width of a jet printing pattern. The spray nozzles of each nozzle module are correspondingly controlled by a valve mechanism. When jet printing is carried out, the valve mechanism corresponding to a graph site quickly opens. Ink is jetted on constant pressure in each nozzle module to form a graph on the surface of the medium which moves relative to the nozzle. The nozzle has the advantages of strong expansibility, precise ink drop control and wide ink adaptation range, expands the types of jet printing mediums, and improves jet printing speed and precision.
Description
Technical field
The present invention relates to a kind of ink-jet shower nozzle, particularly one way and print module combined type shower nozzle and the jet printing method of whole ink-jet media width.
Background technology
Ink-jet technology is exactly ink droplet to be ejected into the moulding that forms figure, literal or other design shape on the spray printing medium by shower nozzle, and ink-jet technology mainly adopts continous inkjet technology (CIJ) and drop on demand ink jet technology (DOD) at present.Continous inkjet technology (CIJ) refers to nozzle continuous injection ink droplet, and ink droplet is through the deflection of charging, corresponding digital signals, and a part of spray printing is to medium, and another part is recovered and recycles, and the small characters ink jet numbering machine is exactly the use typical case of this technology.Drop on demand ink jet technology (DOD) mainly contains little piezoelectric type and heat foamable formula two large classes.Micro Piezo technology was divided into for three steps to the control of the ink droplet in the ink jet process, at first piezoelectric element shrinks under the control of the signal of telecommunication, then piezoelectric element begins to stretch out, push ink droplet to nozzle, at last in moment that ink droplet is about to fly away from nozzle, element shrinks again, and ink level is shunk from nozzle.This process can make ink droplet precisely controlled, and the ink droplet of each ejection generally all can keep perfect shape and correct heading in the distance of nozzle 8 millimeter.This shower nozzle manufacture difficulty is large, and is strict to ink, and the spray printing distance is short.The principle of heat foamable is that ink is packed in the very small capillary, rapidly ink is heated to boiling point by a miniature heating cushion, generate very small steam bubble, the nozzle that capillary end is just extruded ink in the steam bubble expansion forms ink droplet, stopped heating, the ink cooling, cause the steam bubble contraction of condensing, flow thereby stop ink, until produce again steam bubble next time, generate new ink droplet, this technology is used extensively at the heat foamable wide format printer.Adopt the China ink head of heat foamable technology in high temperature, hyperbaric environment, to work for a long time, except nozzle erosion seriously, easily cause drop flight and mouth obstruction etc. simultaneously.Aspect the spray printing quality, owing in use want heating ink, and ink is easy to occur chemical change under the high temperature, character is unstable, and real colour will be subjected to impact to a certain extent; Because ink sprays by bubble, the directionality of ink particulate and the bad grasp of volume size are printed line edge easily uneven, have affected to a certain extent the spray printing quality on the other hand.Little piezoelectric type and heat foamable formula shower nozzle all are by the disturbance of ink in the nozzle passage is produced ink droplet, and the jet power of ink droplet is less, and General Requirements is no more than 8 millimeters apart from the distance of spray printing medium, to uneven or have the dielectric surface of lint to be difficult to adapt to.Because it is less that the present shower nozzle of restriction of processing technology and manufacturing cost is all done, the spray printing width generally all is no more than 4 inches, with the most use is 1 inch, when spray printing surpasses the medium of shower nozzle spray printing width, the vertical direction that can only rely on the shower nozzle relative medium to move comes flyback retrace to finish spray printing, seriously restricts spray printing speed.
