Description
Technical field
The present invention relates to industrial code-spraying machine technology field, particularly a kind of parallel double mouth CIJ code spraying system.
Background technology
Ink jet numbering machine is that one is by software control, use the equipment of cordless at the enterprising line identifier of product, mainly formed by ink-jet coded system and ink system, the printhead of electric deflection formula continous inkjet ink jet numbering machine comprises a high-voltage deflection system, make the deflection of charged ink dot in electric field realize the reduction of character by this high-voltage deflection system, this class ink jet numbering machine is called CIJ ink jet numbering machine conventionally.
As shown in Figure 1, ink system is made up of ink tank 10, compression pump 20, spray gun seat 30, accumulator tank 40, recovery pump 50, nozzle 31 is installed on spray gun seat 30, nozzle 31 fronts are installed charging slot 60, the phase-detection utmost point 70, high-voltage deflection plate system 80 successively, spray gun seat 30, charging slot 60, phase-detection electrode 70 form a code spraying system with high-voltage deflection plate system 80, wherein high-voltage deflection plate system 80 is made up of a pair of positive and negative electrode deflecting plates, crystal oscillator bar is installed in spray gun seat 30, provides crystal oscillator signal by the brilliant loop 90 that shakes that connects crystal oscillator bar, the operation principle of its code spraying system is as follows: ink is under the effect of compression pump 20, nozzle 31 exits at spray gun seat 30 have formed an extrusion system, ink under pressure forms a superfine ink stream from nozzle 30 aperture ejections, conventionally be referred to as the line of ink marker, forming after the line of ink marker due to nozzle 31 rear end crystal oscillator vibration of bar effects, thereby the needed ink dot of formation system (ink droplet), ink dot is now similar to the electron stream that kinescope electron gun sends, but now not charged can not deflecting as electron stream also of ink dot, next on ink dot could allow specific ink dot band during through the charging slot 60 of below, electric charge becomes the charged particle that deflected by electric field force effect, this process is called again ink dot charging.
The ink droplet that need to be used must be according to bringing corresponding negative electrical charge, therefore require ink dot after negative electrical charge, could separate from the line of ink marker on tape, and the voltage that ink dot has charged on rear charging slot 60 also should disconnect immediately, can not charge to an adjacent rear point ensureing. In the situation that ensureing that sine voltage amplitude, frequency are suitable, sinusoidal voltage is added on crystal oscillator bar and will produces and print required ink dot; And the line of ink marker spraying from nozzle 30 will just can split into ink dot completely through certain distance, therefore can be by adjusting the relative position of nozzle 30 and charging slot 60, make ink droplet division just in time occur in the middle part of charging slot 60, can on hardware, meet like this requirement of correct charging. Key is determining of " phase place " opportunity, and the time point and the division generation moment that only apply charging pulse keep suitable phase relation, just can make ink droplet carried charge optimum, and there will not be the situation of multiple ink droplets chargings. In the time that electronegative ink droplet passes through the phase-detection utmost point 70, on detecting electrode, can produce corresponding induced signal, now testing circuit can judge that whether the charging process of a upper link is correct, whether correctly detects the actual institute of ink droplet carried charge.
Ink dot through correct charging will produce deflection when through high-voltage deflection plate system, after deflection, be printed on and on object, form coding, print character, not deflection of uncharged ink dot and directly fall into accumulator tank 40 and turn back to ink system, then pump into ink tank 10 by recovery pump 50 and realize and recycling.
The reduction of picture and text realizes by ink dot, the corresponding ink dot of each picture and text point, and the ink dot that in the unit interval, print What needs more is just more. In CIJ ink jet numbering machine, the generation of ink dot is to control by crystal oscillator frequency the number of ink dots spraying in the time per second, and crystal oscillator frequency neither arbitrarily be set, need to be all kinds of according to ink, jet sizes etc. are set, suppose that crystal oscillator frequency is 62.5KHz, i.e. an ink dot of every 16us ejection. Because the track of each not charged ink dot motion is identical with environment of living in, ignoring under the impact of ink dot gravity and air drag, each ink dot by the speed with identical through charging zone, phase-detection district and high-voltage deflection district, and all equidistant between ink dot. In order to improve spray printing speed, just must within the time per second, increase by the quantity of charging ink dot, in other words, make exactly more ink droplet spray printing on object instead of be recovered. This just requires facing mutually two nearer ink dot chargings, and in the time that the utilization rate of ink dot reaches 100%, all ink dots are all charged, and are now the theoretical limit spray printing speed of this ink jet numbering machine.
The nozzle of general little word machine is generally 60 μ m left and right, crystal oscillator frequency is mostly in 62.5KHz left and right, print resolution comparatively attractive in appearance is 60DPI, 62500 ink dots of this type ink jet numbering machine generation per second, if printing a graph text information dot matrix height is 24 dot matrix, be equivalent to every printing and need to use 24 ink dots once being listed as, therefore the columns that multipotency per second is printed is exactly that now printable columns per second is in the time that 62500 all ink dots are all used: 62500/24=2605 row; Calculating printable length by 60DPI resolution ratio is 2605/60=43.4 inch, 110.236 centimetres to approximate 66 meters of 1.1 metre per second (m/s)s per minute, speed is now less than the speed of production of many modern production lines, improve print speed and conventionally can only reduce print What, if original printing height is adjusted into 16 dot matrix from 24 dot matrix, limit velocity now can reach in theory 99 meters per minute; If by dot matrix height adjustment for only printing a line numeral or alphabetical, can be set to 7 dot matrix, now theoretical velocity can reach 227 meters per minute; Therefore in many high-speed production lines, can not realize with an ink jet numbering machine printing of multiple line content.
And, above print speed is also theoretical computational speed, when actual printing, can not completely each ink dot be used, because CIJ ink jet numbering machine is to adopt the principle work of the charged electric deflection of ink dot of allowing, therefore each ink dot is except being subject to gravity and extraneous wind-force and humidity impact, and after ink dot utilization rate increases, between charged ink dot, the interaction of electrostatic force is more obvious.
As shown in Figure 2, in existing CIJ ink jet numbering machine, also has a kind of improvement project that two code spraying systems arranged side by side are set, this design has identical two spray gun seats 30, two charging slots 60, two phase detection devices 70, two high-voltage deflection plate systems 80 and two accumulator tanks 40, it is actual is that independently two shower nozzles are that printhead is combined into printheads with two spray sprays by physical unit, adopt in theory the printhead that can be combined in this way any nozzle, this double-nozzle spray code system is generally used for needing to print the situation of more contents, the independent jet printing appts of two covers by a shower nozzle the inside can obtain the spray printing height that doubles single injector code spraying system, generally be applied to the lifting that realizes print speed in the printing situation that print What line number exceeds 3 row.
In view of this, the inventor furthers investigate CIJ code spraying system, proposes a kind of parallel double mouth CIJ code spraying system, adopts a spray gun seat that the design of two nozzles is set, and to improve print speed, this case produces thus.
