Abstract
A method for the formation of droplets for printing from meltable powdered, solid or highly viscous inks which contains a paint containing electrical powder and a non-electric meltable carrier. The process of the method comprises reducing the viscosity of the inks by heater to a viscosity by which the melting ink is capable of flowing to the ejection location, supplying an potential to the ejection location to form an electric field, and setting an point-heater on the ejection location for reducing the viscosity of the inks to a viscosity of droplet formation, thus the droplet is formed by the material of reduced viscosity on the ejection location and ejects on the direction of away from the ejection location by electrostatic means.
Description
The present invention relates to from the fusible material of solid-state, powder or high viscosity, produce the method and apparatus of the drop of material.
For non-impact printer, the present invention's a kind of specific use that can be used is that drop with the high strength color material is transferred to recording surface.But, be appreciated that to the invention is not restricted to be that nonimpact printing transmits coloured material, and can be used to produce the drop of material usually or material is coated on the matrix with the pattern of regulation.The example of other application is for being used for the aerosol of security code associated with phosphor coating or fluoro phosphor, hot-melt adhesive and non-propelling (propellantleas), particulate medicament and spraying microparticles medicament that non-propelling acceptable on the useful as drug of the present invention, meltable carrier is produced.
But the present invention will be applied to printing to it and be discussed, and as noted, its scope is more extensive than the above (printing).
Some devices multi-form, that be used for the nonimpact printing system that is referred to as ink jet are usually arranged.It is very common that printing ink is supplied with by nozzle.The outlet diameter of this nozzle is a principal element of determining the drop size, and therefore, the big or small drip point that is obtained will be dispersed on the record surface.Drop can produce in the nozzle continuously, and in this case, the method is called " printing continuously " or they can be produced separately on demand, and in this case, the method is called " pressing the consumption printing " (drop-on-demand printing).In printing continuously, printing ink transmits by nozzle under high pressure, and the pressure on nozzle is by constant basically frequency fluctuation, and this causes the drop of a series of constant size.By electric charge being applied to the outside of arriving nozzle on the drop with electric field action, selected drop can be displaced on the recording surface in their passages with the signal that produces electric field, therefore, according to this control number letter, can form pattern on recording surface.The drop of consumption printing is on demand controlled by producing local pressure pulsation near the fluid little nozzle, and this local pressure pulsation causes spraying from nozzle in the selected time droplet of fluid.
No matter in the jet printing of the sort of type, coloured material is that the soluble dye that combines with binding agent is with more permanent printed image in the liquid-carrier that provides.
The shortcoming of soluble dye is that printed image density is not sufficiently high in many application scenarios, and dyestuff can make image fade (fading away) being exposed under the extraneous occasion.Another shortcoming of solubility coloring material is the performance that the quality of printed image depends on recording surface.
As you know pigment ink can make than soluble dye density high the image and also be to preserve more permanent image, pigment also can be used from jet printers with carrier liquid one.But the image of hard produce need be in liquid-carrier the high concentration paint material, the paint material of high concentration can influence the drop separation in the continuous printing (machine), and causes uneven printing.Drop printing machine by consumption does not have high continuous pressure, and drop produces the own condition depend on nozzle consumingly, and therefore, the existence of pigment can improve state of this nozzle own or nozzle capable of blocking, in order to avoid liquid droplets improperly.
As the another kind of method of known electrostatic ink jet printing, its characteristics are the electrostatic attraction on the liquid (drawing gravitation) and as an example at United States Patent (USP) 3,060, have done announcement in 429.This comprises by the high voltage of the maintenance between nozzle and the pressing plate producing from the nozzle that contains liquid and has the electric charge drop and quicken to reach the pressing plate electrode.This method is further optimized by a valve formula electrode is housed, and this electrode can interrupt or control injection stream, and two pairs of electrodes as the range track of control drop are housed.Printing then can be by just in time placing paper substrate and using the ink solutions of conduction to finish before the pressing plate electrode.For example at U.S. Patent number 3,653, a kind of printing ink of solid is at room temperature used in suggestion once in 932, and by high voltage before inking is given nozzle and crossing the gap and be melted in printing ink in the heating container before continuously printing ink being attracted to substrate.This system and device have unnecessary complicated shortcoming to the adjusting of regulating between nozzle and the valve formula electrode and the voltage difference between the pressing plate of substrate is housed at the valve electrode with when printing.Similarly device is at IS﹠amp; The article of publishing in the 8th international executive session of T ' s, the prospect (1992) 334 of nonimpact printing technology ... be described in 339 pages.
The objective of the invention is in order to provide a kind of from method and apparatus such as formation drop the such material meltable pulverous, solid-state or high viscosity of printing ink, in these method and apparatus, drop is not produced by nozzle, thereby the size of drop is not subjected to the size impact of nozzle.
It is a kind of from such as the such material meltable pulverous, solid-state or high viscosity of printing ink and the method and apparatus that forms drop in high concentration pigment or other solid-state material that another object of the present invention is to provide, and maybe can produce the drop with relatively large solid-state material so that can form high brightness (intensity) image on recording surface.
A further object of the present invention is in order to provide a kind of from such as the printing ink that contains carrier or use method and apparatus conductive carrier not necessarily, that form drop the meltable material pulverous, solid-state or high viscosity.
Thereby in a kind of mode, described invention belongs to the method that forms drop from meltable material Powdered, solid-state or high viscosity, and its step comprises that the viscosity that makes material is reduced to the viscosity that can form drop; Supply with blow-off point reducing viscosity material; Current potential is added to the ejection position to form electric field at that point; Thereby the material that makes visbreaking forms drop and by electrostatic equipment this drop is sprayed from blow-off point on blow-off point.
Material pulverous, solid-state or high viscosity can be a kind of printing ink that contains colouring agent and carrier.Colouring agent then can be a pigment.
Viscosity can reduce by heating or pressurization.
This shows, the size that does not depend on arbitrary nozzle according to the drop size of the such material of the present invention such as printing ink, nozzle is sent to blow-off point to the visbreaking material, but it depend on the intensity level of blow-off point physical dimension, electric field, in the character and the viscosity when it sprays that add heat and the visbreaking material as printing ink on the blow-off point.
The difference that therefrom can also see the present invention and prior art is when drop forms, at the carrier liquid that not necessarily will contain conduction such as the such visbreaking material of printing ink.Drop can be thought to utilize electrostatic equipment and be formed, and electrostatic equipment can work to the particle such as the such solid of the pigment in the ink material of visbreaking.The liquid part only plays carrier.The transmission of the transmission replacement coloring material liquid solution of pigment means the image that can form better shading value (brightness) on substrate and can utilize and faster adjust the meticulous spot size of some formation.
In a kind of optimised form of the present invention, the current potential that forms electric field can be pulsed, so that form periodically and liquid droplets from blow-off point.
Current potential will make electric field be based upon on the blow-off point and can decide with the physical dimension such as the blow-off point of the radius of curvature of blow-off point, in most preferred embodiment of the present invention, blow-off point can be provided by the pin that has radius of curvature 5～50 particulate scopes on its top.On the other hand, blow-off point can be made of the sharp edges of elongation.May or have the blow-off point of ranks (matrix) at some blow-off points along the elongation edge.
Method of the present invention can produce diameter at 1～500 micron size range even bigger drop as materials such as printing ink, and this situation then depends on bearer type contained in the geometry, viscosity, material of blow-off point and the voltage that is applied.
Under the situation that lowers in viscosity, in the liquid that the carrier part of material is preferably non-conductive, printing ink as the solid material of pigment etc. then by forming by charged particle.Preferably, electrifiable particle can be charged to as the polarity that is applied to the voltage on the blow-off point.
Being applied to current potential on the blow-off point can be in 500 to 6000 volts scope or higher.
In a kind of interchangeable form, the present invention can be considered to belong to the device that produces the drop of material from fusible Powdered, solid-state or high viscosity material, this device comprises that one can make the viscosity of material pulverous, solid-state or high viscosity ease down to can to make the device, of the viscosity that drop forms that the supply of the material of visbreaking is given the device of blow-off point and current potential is applied to blow-off point to form the device of electric field at that point, therefore, making can be from the water drop of blow-off point formation and blasting materials.
Moreover material pulverous, solid-state or high viscosity can be a kind of printing ink that contains colouring agent and carrier, and colouring agent can be a kind of pigment.
Viscosity can be reduced by heating or pressurization.
Can see that the device that provides according to this form of the present invention can and spray fusible drop pulverous, solid-state or high viscosity material from the blow-off point generation.
The liquid stream that lowers cohesive material is supplied with the position of giving blow-off point can be reached by various devices according to the original character of material.
Under the situation of solid fusible material, a spring stand under load chamber that the particle or the bar of fusible material are housed can be arranged, on an end of the most close blow-off point, it is provided with one and is suitable for fusible material is melted to the heater that needs viscosity.On the other hand, the two-stage heating can be arranged, the first order is applicable to fusible material is softened to such gluing, and makes and can be pressed to second level heater to fusible material under spring pressure, and second level heater makes the viscosity of fusible material be reduced to final required viscosity.For using some printing ink, found that if they are contained in the container of a vertical sealing, the two-stage heating by means of gravity and/or the expansion of material when heating helps visbreaking and drop is delivered to blow-off point.
This heating can be induction type resistance type or so-called.
The heater of resistance type can be the resistance wire that twines around container of material.
The induction type is made up of a coil that is wound on the FERRITE CORE, and this coil is juxtaposed with respect to the container that printing ink is housed.Call by name, coil can be wound on the container, and wherein, described container then plays a magnetic core, and directly can heat printing ink.
Blow-off point also can be heated to keep required ink viscosity.
This heating of blow-off point can be constant or pulsation.The heating of blow-off point can be a kind of point source heater such as infra-red laser diode.
Under the situation of powdery ink, powder feeder can be used to the powder feeding heater stages and to make powder be not that one-level is exactly that secondary adds to pine for softening and can spray required viscosity.
Under the situation of high viscosity printing ink, this shell that spring stand under load piston can at one end be housed is supplied with.Spring pressure is suitable for cream pasty state or syrupy shape printing ink directly are pushed to heating clamber.

This heater can present some characteristic properties, for example fast conversion time, with respect to the suitable heat output of wavelength and frequency bandwidth, the thermal power of fusing such as materials such as printing ink and with respect to the spot size that is fit to of blow-off point size.
Generally speaking, the invention provides as can be seen that drop on blow-off point forms and the electrostatic spraying of this drop.
Although do not understand the mechanism that drop forms fully, the theory that a kind of theoretical applicant Mo Bi is fettered is as follows: the particle that flows to the visbreaking material of blow-off point was charged originally or was charged to and polarity is ordered the same in ejection.Increasing particle accumulates on the blow-off point in the formation drop of material support liquid continuously, along with repulsion increases, these particles are increased to such degree to the electrostatic repulsion that the direction of leaving blow-off point moves between blow-off point and formation charged particle drop, and promptly feasible surface tension of carrying the liquid of carrier secretly can make drop no longer remain in blow-off point.In this stage, drop is discharged by electrostatic equipment.
To notice that especially it is unwanted that drop is attracted to on-chip ground connection substrate because repulsive force is essentially static, in fact, before drop bump substrate, sizable drop flying distance can occur.This drop can be suitable for deflecting apparatus static or other form to make the pattern that whatsoever all needs drop on substrate.
Device can comprise a pair of blow-off point, and each produces the drop of a kind of composition of two kinds of composition adhesive agent systems.This can equip an adhesive agent spray gun.
