Referring to Fig. 5, be provided with paper advance mechanism in paper feed passage 12, be used for continuous print media is moved horizontally along paper feed passage 12.Described paper advance mechanism comprises chart drive motor 14, paper feed Timing Belt 15, synchronous pulley 16, the first gear 17, the second gear 18, First Transition gear 19, the first dancing roll 20, the first friction pulley 21, the second dancing roll 22 and the second friction pulley 23 etc., wherein, the first gear 17 is fixed on the roll shaft right part of the first dancing roll 20, the second gear 18 is fixed on the roll shaft right part of the second dancing roll 22, First Transition gear 19 is engaged between the first gear 17 and the second gear 18, so that transmission of drive force.The first dancing roll 20 and the first mutual frictional fit of friction pulley 21 common consist of the first paper feed unit that is positioned at printhead 24 front sides; The second dancing roll 22 and the second mutual frictional fit of friction pulley 23 common consist of the second paper feed unit that is positioned at printhead 24 rear sides.The output of chart drive motor 14 is connected with synchronous pulley 16 by paper feed Timing Belt 15, coaxial second gear 18 that is fixed in of synchronous pulley 16.The axial outside of synchronous pulley 16 is equipped with grating encoder 25 and photoelectric encoder 26, is used for to Master control chip feedback paper feed amount information.The axial side of the second friction pulley 23 is provided with the sensor 3 that is connected to Master control chip, its effect is whether the continuous print media of induction exists to control chart drive motor 14 and begin rotation, and is used for confirming that continuous print media front position begins to calculate to control Master control chip.
Referring to Fig. 1 and Fig. 4, when being used for printing the such continuous print media of porose continuous paper, paper feed port 31 places also are provided with continuous media and drag paper device 32, are used for porose continuous paper is sent into paper feed passage 12.Continuous media drags paper device 32 to be provided with near a side of left wallboards 3 and drags paper device driven gear 33, and the roll shaft left part of described the second dancing roll 22 is provided with the 4th gear 34, drags between paper device driven gear 33 and the 4th gear 34 and is engaged with the second transition gear 35.
The first friction pulley 21 and the second friction pulley 23 can be cylindrical wheel as shown in Figure 6, and adopting the advantage of cylindrical wheel is simple shape, easy to process; Also can adopt the cydariform wheel as shown in Fig. 7 a and Fig. 7 b, its advantage is the defective that can avoid in injection moulding, reducing paper wanders off (if make cylindric, needs and moulding shrink due to the mould depanning, after actual moulding, cylinder can be one large one small, causes paper paper feed discontinuity, wanders off).In addition, can also adopt the eel-like figure cylindrical wheel as shown in Fig. 8 a and Fig. 8 b, its advantage is identical with above-mentioned cydariform wheel; Perhaps the DVD multidisc shape as shown in Fig. 9 a and Fig. 9 b is taken turns, and its advantage is at utmost to avoid dirty China ink; Can also be the rice word shape wheel as shown in Figure 10 a and Figure 10 b, its advantage be that to can be used for rectifying paper oblique.
The transmission principle of above-mentioned paper advance mechanism is as follows: chart drive motor 14 drives synchronous pulley 16 by paper feed Timing Belt 15, synchronous pulley 16 rotarily drives the second dancing roll 22 and carries out active rotation, and the second friction pulley 23 is by producing passive rotation with the second dancing roll 22 frictional fit; Simultaneously, also drive the second gear 18 rotations during synchronous pulley 16 rotation, the second gear 18 drives the first gear 17 rotations via First Transition gear 19 transmission of drive force, the first gear 17 rotarily drives the first dancing roll 20 and carries out active rotation, and the first friction pulley 21 is by producing passive rotation with the first dancing roll 20 frictional fit.In addition, the 4th gear 34 of the roll shaft left part of the second dancing roll 22 is in the second dancing roll 22 rotations, drive via the second transition gear 35 transmission of drive force and drag 33 rotations of paper device driven gear, drag the traction on paper device 32 to turn round thereby drive continuous media.
Continuously print media under the clamping of the clamping of the first dancing roll 20 and the first friction pulley 21 and the second dancing roll 22 and the second friction pulley 23, can move horizontally along paper feed passage 12.For the so continuous print media of porose continuous paper, also drag the projection 37 on the traction of paper device 32 to drive motion by continuous media.
The present embodiment has two kinds of working methods:
1, print porose continuous paper
continuously print media be installed at continuous media drag on paper device 32 → continuous media drags 32 runnings of paper device and continuous print media sent into by the paper feed port 31 of rear side paper feed passage 12 → the print media front end moves to the existence that 36 times → sensor of sensor 36 detects continuous print media continuously, and send signal → Master control chip and receive signal, confirm continuous print media front position, and begin to calculate, continuous print media move to the position that needs print What begin to print → while printing from exit slot 13 paper deliveries of front side → until Print All complete → paper delivery or treat down to open printing.
2, print the coil paper of atresia
under the effect of external force or other mechanisms, the print media front end is sent into paper feed passage 12 by the paper feed port 31 of rear side continuously, and shift onto on the second dancing roll 22 → the second dancing roll 22 and the second friction pulley 23 clampings drive continuous print media motion → meanwhile, sensor 36 detects the existence of continuous print media, and send signal → Master control chip and receive signal, confirm continuous print media front position, and begin to calculate, continuous print media move to the position that needs print What begin to print → while printing from exit slot 13 paper deliveries of front side → until Print All complete → paper delivery or treat down to open printing.
Above-mentioned ink jet printing device is owing to having adopted quick drying ink to print, quick drying ink is ejected by printhead and is attached on continuous print media, had cured dry before arriving friction pulley, make the ink marks on continuous print media can not scratched, friction pulley does not speckle with ink marks can not stain the continuous print media of back yet, has avoided the problem of image fault.With respect to L-type and C type paper feed passage, the present invention has realized the yi word pattern paper feed passage on the ink jet printing device, from the whole process of paper feed, printing, paper delivery, print media is open and flat all the time continuously, need not to consider its pliability because of the bending problem of continuous print media, reduced to greatest extent the restriction of ink jet printing device to continuous print media pliability, for the thick continuous print media that number of C type and L-type paper feed passage can't be processed, this yi word pattern paper feed passage can easily be processed.
Certainly, above-mentioned embodiment is only the preferred embodiment of the present invention, during practical application; the present invention can also have more variation; for example, friction pulley can also adopt other suitable shape, and such change is also included within the protection domain of claim of the present invention.
