The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
See also Fig. 1, the schematic diagram of the bubble scavenge system that provides for first embodiment of the invention.This bubble scavenge system 100 is used to remove the bubble in the ink gun.This bubble scavenge system 100 comprises that holding device for ink 10, holds first pressure-generating device 12, one first valve 15, ink recovery device 16 that device for ink 10 is connected and second vacuum extractor 17 that is connected with this ink recovery device 16 with this first vacuum extractor 11 that holds that device for ink 10 is connected, with this.This holds and contains ink 101 in the device for ink 10.
This bubble scavenge system 100 is as follows with this annexation of ink gun 14 of waiting to remove bubble.This waits that the ink gun 14 of removing bubble has ink input 141 and ink output 142, holds device for ink 10 and is communicated with the ink input 141 of this ink gun 14 by conduit 13.Wherein, this position of holding device for ink 10 is higher than the position of this ink gun 14.The ink output 142 of this ink gun 14 links to each other with an end of first valve 15 by conduit 18, and the other end of this first valve 15 is communicated with ink recovery device 16 by a conduit 20 and a snap joint 19.Wherein, an end of this snap joint 19 directly inserts this conduit 20, and the other end directly is installed on this ink recovery device 16.
Second embodiment of the invention provides the bubble scavenge system of a kind of employing first embodiment to remove the method for bubble in the ink gun.This method may further comprise the steps:
At first, open first valve 15 and second vacuum extractor 17, open first pressure-generating device 12 again, exert pressure to being contained in this ink 101 that holds in the device for ink 10, this ink 101 is pressed into conduit 13, this ink 101 flows into this ink gun 14 via the ink input 141 of ink gun 14, and the bubble in this ink gun 14 is released by ink 101, enters conduit 18 together with ink 101 through the ink output 142 of this ink gun 14.17 pairs of this second vacuum extractors should be bled in this ink recovery device 16, and the air pressure in this ink recovery device 16 is reduced, and made this bubble flow into this ink recovery device 16 together with ink 101 via conduit 20.
Then, whether Visual Confirmation ink 101 is full of conduit 13 and conduit 18, during no bubble, closes this first valve 15 and this second vacuum extractor 17 in ink 101 is full of this conduit 13 and conduit 18 and this conduit 13 and conduit 18.Hold at this first pressure-generating device 12 and by this under effect of device for ink 10 and the pressure of difference in height generations of this ink gun 14, ink 101 enters nozzle by this ink gun 14, and is oozed by this nozzle, has removed the interior bubble of this nozzle simultaneously.
After removing the bubble in this nozzle, close this first pressure-generating device 12, open and be connected in first vacuum extractor 11 that this holds device for ink 10, this is held device for ink 10 bleed, this air pressure that holds in the device for ink 10 is reduced.So this ink 101 that holds in the device for ink 10 can not oozed by nozzle because of the pressure that this difference in height of holding device for ink 10 and this ink gun 14 produces.
At last, pull up this snap joint 19, the ink 101 in this ink recovery device 16 is utilized after treatment again.
See also Fig. 2, the schematic diagram of the bubble scavenge system that provides for third embodiment of the invention.This bubble scavenge system 200 further comprises with respect to the bubble scavenge system 100 that first embodiment of the invention provides: second pressure-generating device 21, removal air bubble apparatus 24 and second valve 26.
This bubble scavenge system 200 is with the difference of the bubble scavenge system 100 that first embodiment of the invention provides: be communicated with by conduit 20 between first valve 15 and the ink recovery device 16, this ink recovery device 16 is connected with this second pressure-generating device 21, this ink recovery device 16 is communicated with removal air bubble apparatus 24 by a conduit 23, and this is removed air bubble apparatus 24 and is connected with an end of second valve 26 by conduit 25.The other end of this second valve 26 is connected with ink recovery device 10 by conduit 27.
Fourth embodiment of the invention provides the bubble scavenge system of a kind of employing the 3rd embodiment to remove the method for bubble in the ink gun.This method may further comprise the steps:
At first, open first valve 15 and second vacuum extractor 17, open first pressure-generating device 12 again, exert pressure to being contained in this ink 101 that holds in the device for ink 10, this ink 101 is pressed into conduit 13, ink 101 flows into this ink gun 14 via the ink input 141 of ink gun 14, and the bubble in this ink gun 14 is released by ink 101, enters conduit 18 together with ink 101 through the ink output 142 of this ink gun 14.17 pairs of these ink recovery devices 16 of this second vacuum extractor are bled, and the air pressure in this ink recovery device 16 is reduced, and this bubble flows into this ink recovery device 16 together with ink 101 via conduit 20.
Then, Visual Confirmation ink 101 is full of conduit 13 and conduit 18, when in this conduit 13 and the conduit 18 during no bubble, closes this first valve 15 and this second vacuum extractor 17.Under the effect of this first pressure-generating device 12, ink 101 enters nozzle by this ink gun 14, and is oozed by this nozzle, has removed the bubble in this nozzle simultaneously.
After removing the bubble in this nozzle, close this first pressure-generating device 12, open and be connected in first vacuum extractor 11 that this holds device for ink 10, this is held device for ink 10 bleed, this air pressure that holds in the device for ink 10 is reduced.So this ink 101 that holds in the device for ink 10 can not oozed by nozzle because of the pressure that this difference in height of holding device for ink 10 and this ink gun 14 produces.
At last, open second valve 26 and second pressure-generating device 21, ink 101 in the ink recovery device 16 and bubble are pressed into removal air bubble apparatus 24 by conduit 23, remove air bubble apparatus 24 by this and remove these bubbles.The ink 101 of this removing bubble flows into this by conduit 25 with conduit 27 and holds device for ink 10, is convenient to this bubble scavenge system 200 cycling and reutilizations.
Being appreciated that ink 101 in the ink recovery device 16 and bubble also can directly not be recycled to holds device for ink 10, but flows into the ink supply unit of ink discharge device by valve, is supplied with the ink gun of ink discharge device again by this ink supply unit.
Compared to prior art, use bubble scavenge system of the present invention not only can utilize to hold the ink of accommodating in the device for ink and flow through ink gun, remove the bubble in this ink gun, and this ink recovery can be utilized again.In addition, the method for bubble can be removed the bubble in the ink gun fast, up hill and dale in the described removing ink gun, when using this ink gun of having removed bubble to carry out inkjet printing, can improve the effect of inkjet printing.
In addition, those skilled in the art can also do other variation in spirit of the present invention, certainly, the variation that these are done according to spirit of the present invention, all should be included in the present invention's scope required for protection in.
