Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail. As shown in Figure 1, a kind of printer head purging system, comprises shower nozzle and is arranged on the cleaning device on shower nozzle. Shower nozzle comprises inking chamber 11, is arranged on the minitype piston 12 being slidably connected with inking chamber in inking chamber 11 and the piston controller 13 that is electrically connected minitype piston 12. Inking chamber 11 comprises the nozzle that is arranged on bottom, and leads to the ink entrance 112 of ink inlet tube. Nozzle is included in entrance that top communicates with inking chamber, is arranged at the outlet of bottom and is communicated with the passage 1111 of entrance and outlet, the bore of entrance is greater than the bore of outlet, and ink flow to outlet ejection along the vias inner walls tilting after entrance enters nozzle.
Cleaning device comprise be arranged on minitype piston bottom cleaning head 21, be arranged at the waste water reclaiming device of nozzle below. Cleaning head comprises rotary electric machine, be arranged on surperficial cleaning wall 212, be embedded at the capillary 213 on cleaning wall surface; Capillary communicates with waste water reclaiming device by the collecting pipe 214 of cleaning head inside, and cleaning wall surface arranges Clean Brush for cleaning. Waste water reclaiming device comprises the wastewater collection passage 221, waste water pump 222 and the wastewater filter box 223 that are provided with recovery mouth 2211; Waste water pump 222 is for being delivered to wastewater filter box 223 from the waste water of wastewater collection passage, and cleaning head is led in the outlet of wastewater filter box 223, communicates with the collecting pipe 214 in cleaning head.
The passage of nozzle comprises conduit wall, and conduit wall is provided with deformation layer 11111, zone of heating 11112 and electrostatic layer 11113 from the inside to the outside successively. Deformation layer 11111 comprises along ink and flows to the Piezoelectric Driving plate 111111 setting gradually. Zone of heating 11112 comprises Electric radiant Heating Film. Electrostatic layer 11113 comprises electrostatic film. The inwall setting of the inking chamber of nozzle top from top to bottom respectively with flow to the Piezoelectric Driving plate that once arranges along ink one to one, for controlling the switch of Piezoelectric Driving plate. Switch comprises the conducting block of being made up of conductive material such as copper 113 that is embedded in inking chamber inwall, and the both sides outer wall of minitype piston 12 arranges the power supply bar 121 corresponding with conducting block 113, and power supply bar 121 is electrically connected with power supply, is the power supply of Piezoelectric Driving plate by conducting block. In the time that minitype piston from top to bottom moves in inking chamber, power supply bar 121 is gradually near conducting block 113. Power supply bar is less than the length of conducting block 113 at vertical direction in the length of 121 vertical directions, power supply bar 121 is along with minitype piston from top to bottom transports, while touching conducting block 113, conducting the circuit between power supply and Piezoelectric Driving plate corresponding to conducting block 113, make Piezoelectric Driving plate after energising, produce the deformation towards nozzle interior bending. Along with minitype piston continue move downward, power supply bar 121 leaves first conducting block, moves to second conducting block of this conducting block below, drives second the Piezoelectric Driving plate generation deformation that conducting block is corresponding, by that analogy. In the process of from top to bottom moving along with minitype piston, Piezoelectric Driving plate is also from top to bottom once opened and is produced deformation, promotes the ink on conduit wall surface toward current downflow (as Fig. 4). Zone of heating 11112 comprises Electric radiant Heating Film, and Electric radiant Heating Film heats conduit wall, prevents that ink is dry and hard on conduit wall surface. Electrostatic layer 11113 comprises electrostatic film, and electrostatic film produces static, to ink particle generation effect, makes ink particle leaving channel wall surface, keeps the clean of conduit wall surface.
When printing, ink is entered in inking chamber through ink entrance by ink inlet tube, then by the nozzle ejection identical with inking chamber, completes printing. Minitype piston and described inking chamber is airtight is slidably connected, prints after finishing and can under the control of described piston controller, in described inking chamber, continue to move downward, and ink residual in described inking chamber is released.
The course of work of printer head of the present invention is as follows:
While starting to print, ink enters in inking chamber through ink inlet tube, prints work by nozzle ejection. In the course of work, the zone of heating of conduit wall and electrostatic layer can be switched on by strengthening the mobility of ink, print procedure ink inside are flowed more unobstructed. In print procedure, minitype piston also can be under the effect of piston controller, up and down in the space in inking chamber more than switch, further promotes flowing of ink, increases the thrust of the ejection of ink.
Print while end while finishing soon (or), minitype piston moves downward under the promotion of piston controller, minitype piston is in the process that continues to press down, power supply bar contacts successively with conducting block, open Piezoelectric Driving plate and flow to effect generation deformation successively along ink, promote the ink on conduit wall surface toward current downflow. The ink that deformation layer produces deformation guiding channel wall surface is along conduit wall to downstream to outlet. Zone of heating is heating conduit wall, prevents that ink is dry and hard on conduit wall surface. Be positioned at most surface electrostatic layer produce static to ink particle generation effect, make ink particle leaving channel wall surface. By the multiple action of distortion, heating and static, reduce the ink being attached on conduit wall. Minitype piston continues in the process of down motion, and cleaning head is pushed in the outlet of shower nozzle. Rotary electric machine drives cleaning head to rotate, and makes the clean brush cleaning outlet inwall in cleaning wall. The waste water of Clean-mistake is collected through the wastewater collection passage of waste plant, and waste water pump unlatching work simultaneously, is pumped to wastewater filter box by the waste water of collection, and waste water is sprayed the outlet of nozzle is rinsed by capillary after filter cleaning in wastewater filter box.
Although described by reference to the accompanying drawings embodiments of the present invention, those of ordinary skill in the art can make various distortion or amendment within the scope of the appended claims.
