Current RP technical development goes out to utilize Printing techniques in conjunction with the mode of carrier precision positioning technology to produce the physical model of 3D, its mode of production is for be first layed in above carrier by one layer of powder and to utilize the hydrojet printing technique full-bodied binding agent of spray printing on amount of powder, make binding agent and powder stick and solidify, repeat above-mentioned process layer layer stack always and build the physical model that can complete 3D.

It is technical that the known print module generally adopted with general hydrojet printing technique is applied to RP, for example, it is as it is shown in figure 1, the print module 1 that this general hydrojet printing technique adopts is arranged at a main body (not graphic), to carry out spatterwork.This print module 1 includes spray printing platform 10, load bearing seat 11 and at least one hydrojet casket 12, this spray printing platform 10 includes support body 101 and is located at the power transmission shaft 102 of this support body 101, load bearing seat 11 is arranged on this power transmission shaft 102, this at least one hydrojet casket 12 would generally arrange two hydrojet caskets, namely as shown in Figure 1, for the first hydrojet casket 121 of accommodating black hydrojet and accommodating colored hydrojet (such as: cyan (C), yellow (Y), carmetta (M)) the second hydrojet casket 122, and hydrojet casket 12 is correspondingly arranged on this load bearing seat 11, therefore this load bearing seat 11 and the hydrojet casket 12 that is arranged on can relative to this power transmission shaft 102 of this spray printing platform 10 to carry out the reciprocating start of X-axis.

When this print module 1 carries out the spatterwork of RP technology, carry out the reciprocating start of a Y direction with this load bearing seat 11 and the hydrojet casket 12 that is arranged on through this spray printing platform 10, and again can along this power transmission shaft 102 to carry out the reciprocating start of X-direction moved left and right on this load bearing seat 11 through this hydrojet casket 12, the reciprocating start so carried out alternately through X-axis and Y direction, the assorted hydrojet that this hydrojet casket 12 is housed can be sprayed on the construction materials (not shown) that construction carrier (not shown) is laid, and repeat the operation that above-mentioned processing procedure is built with implementation level layer stack always, and then the physical model (not shown) of 3D object can be completed.

Only when the rapid shaping spatterwork of this 3D object is implemented, in hydrojet casket 12 except accommodating black and colored hydrojet, more need additionally to house full-bodied binding agent, so that construction materials is bonded, and then can pile up layer by layer to constitute 3D object, therefore traditional rapid molding device more needs to arrange extra carrier and hydrojet casket for housing full-bodied binding agent, thus, the overall volume that then can cause spray printing module 1 increases, and more increases the cost of carrier and hydrojet casket simultaneously.

Known hydrojet box structure can comprise printing chip, heating resistor and jet orifice plate, wherein hydrojet box structure is to be assembled on the body of a liquid storage casket, and heating resistor is controllable by printing chip, liquid storage casket will provide for hydrojet to heating resistor, hydrojet is heated by heating resistor in response to the triggering of printing chip, make the internal stored hydrojet heating of liquid storage casket and spray to three-dimensional body via the spray orifice of corresponding jet orifice plate, as for, the control of drop hydrojet time is corresponding to the pixel of wanted print pattern.

It is internal that usual liquid storage casket is disposed on liquid-jet device, and just carry out transverse shifting on three-dimensional objects by the drive of a bearing system, the hydrojet casket making liquid storage casket can move to correct position carry out hydrojet according to the pattern to print, namely bearing system makes to produce relative motion along one scan axle between hydrojet casket and three-dimensional body, wherein scan axis refers to the width being parallel to three-dimensional body, and bearing system drives hydrojet casket to move once on the about whole width of three-dimensional body to drive the single sweep operation of assembly to mean, but between each single sweep operation, three-dimensional body will advance along the feed shaft being perpendicular to scan axis relative to hydrojet casket, namely along the direction of three-dimensional body length.

A line will be produced when hydrojet casket moves along scan axis hydrojet and be interrupted lines, the word of the pattern being printing or image and all of interruption lines combine, print resolution as the feed shaft along three-dimensional body is referred to as the density being interrupted lines along three-dimensional body feed shaft, therefore lines density on ink-jet media feed shaft it is interrupted more big, more high along the print resolution of this axle.

Known technology is that the number by the heating resistor increasing hydrojet casket improves the density being interrupted lines along three-dimensional body advance shaft, to improve print resolution, carry out promoting the speed printed, although the number increasing the heating resistor of hydrojet casket can reach to accelerate print speed, but numerous heating resistors can produce substantial amounts of heat energy makes the temperature of hydrojet casket quickly raise, not only can affect print quality and more likely make whole hydrojet casket damage.

One of settling mode that current industry developed is that the size by increase hydrojet casket is to avoid the temperature of hydrojet casket quickly to raise, but, for in hydrojet printing market with keen competition, the quickly speed that the price of liquid-jet device declines, the size increasing hydrojet casket will improve the cost producing liquid-jet device, and cuts down the market competitiveness.

nullAnd when the nozzle hole number of hydrojet casket is many time，Hydrojet casket can be designed as sequence transmit to save the quantity in printing chip input/output (I/O)，But because the required control mode driving heating resistor of printing chip still for needs in conjunction with address control and print data signal，But the design controlled for address in known printing chip is for when controlling the number of address of hydrojet casket heating and being n，Position decoding device need to be correspondingly arranged n bar winding displacement on the ink-jet driving circuit being connected to correspondence，For example，When controlling the number of address of hydrojet casket heating and being 20，Position decoding device need to be correspondingly arranged 20 winding displacements，But it is as the increase of heating resistor number，Known design will increase the area of chip，And increase the size of the printing chip of hydrojet casket，Therefore the major issue that mode is saving printing chip area that address controls how is reduced.

Therefore, a kind of hydrojet box structure improving above-mentioned known technology disappearance, problem also actually in the urgent need to address at present how are developed.

Can be constantly on the 6th of above-described embodiment the switch M6 warmable data signal PFD, but so all of heating resistor R is always maintained at continuing to preheat, such whole hydrojet chip 42 can accumulate at a relatively high temperature, to cause the execution operational paradigm affecting hydrojet chip 42, the more serious heating resistor R causing hydrojet chip 42 burns and can not work.

By described above, the present embodiment to improve above-mentioned disappearance, therefore the best mode of the present embodiment, it is by the clock signal of address signal An corresponding to print data signal PD, and warmable data signal PFD is designed to the clock signal of a kind of corresponding address signal An-1, so that address signal An coordinates different print data signal Data0, Data1, Data2, ..., Data14 etc. produce print data signal PD and warmable data signal PFD through print data lock 4261 and warmable data lock 4260, such as print data signal Data1 and address signal A2 produces output signal D1A2 via print data lock 4261, it is then A1 that warmable data signal A1 produces output signal via warmable data lock 4260.That is, when this heating resistor R implements heating operation, address signal corresponding to this heating resistor R is An, namely it is subject to print data signal PD and thermal control signals MF and is controlled heating running, and heating resistor R is intended to implement preheating running, then it is subject to warm-up control signal PF and warmable data signal PFD and is controlled preheating running.Therefore the corresponding address signal received by heating resistor R being intended to implement heating running is An, and the corresponding address signal received by heating resistor R being intended to implement preheating running is An-1, so only the pre-heating running heating resistor R that implements first is implemented preheating running, and do not have other heating resistors R to implement preheating running in the lump, so all of heating resistor R will not be always maintained at continuing to preheat, avoid whole hydrojet chip 42 can accumulate at a relatively high temperature, cause that the heating resistor R causing hydrojet chip 42 performing operational paradigm or more serious affecting hydrojet chip 42 burns and can not work.

And when print data signal PD is low-potential signal (no-voltage signal), and warmable data signal PFD and warm-up control signal PF is high potential signal (having voltage signal), and the corresponding address signal received by warmable data signal PFD is An-1, conducting is operated by the 5th switch M5 and the 6th switch M6, other switch is not turned on, can trigger, by second switch M2, the control end H current potential driving transistor switch 4263 is high potential signal (having voltage signal), and power supply signal is sent to heating resistor R, make heating resistor R that part hydrojet and hydrojet chip to be preheated.

After preheating completes, when warm-up control signal PF is low-potential signal (no-voltage signal), this reverse warm-up control signal PF-N is high potential signal (having voltage signal) relatively, and warmable data signal PFD is still for being continuously high potential signal (having voltage signal), and the corresponding address signal received by warmable data signal PFD is An-1, such 9th switch M9 and the tenth switch M10 conducting running, other switches are not turned on, switch M9 and the tenth switch M10 by the 9th and switch M1 control end H1 by first, the control end H current potential driving transistor switch 4263 is drop-down for low-potential signal (no-voltage signal), this heating resistor R is made to stop preheating.

According to conception of the present utility model, the control signal of ink-jet controlling circuit 41, i.e. print data signal PD, warmable data signal PFD, the voltage levels of thermal control signals MF and warm-up control signal PF can be different according to different printer models, and the preheating sequential of heating resistor R, only can be input to by An (such as A2) that this print data lock 4261 produced to export print data signal for print data signal and corresponding address signal is PD, address signal is that An-1 (such as A1) only can be input into this warmable data lock 4260 simultaneously, produced output warmable data signal PFD.That is warmable data signal PFD and the corresponding address signal before address signal A2 (An) is A1 (An-1), correspondence can be input in main Warming-up control circuit 4262, promote this heating resistor R to preheat.

In some embodiments, control signal voltage is about 3.3 volts, to reach economize on electricity and to promote effect of efficiency.In like manner, driving transistor switch 4263 of the present utility model is the control end H triggering by second switch M2 and being sent to by power supply signal and drive transistor switch 4263, recycling power supply signal controls to drive transistor switch 4263 to turn on, so this utility model can use the control signal of small voltage to control to drive transistor switch 4263, and then make control mode more effective and convenient.
