But a kind of accurately setting ink injection amount and from the ink-joiner of the harmless fully print cartridge of air intake duct refilling
Technical field
The invention belongs to a kind of ink-joiner, but particularly a kind of accurately setting ink injection amount and from the ink-joiner of the harmless fully print cartridge of air intake duct refilling.
Background technology
Along with popularizing rapidly of computer, driven popularizing rapidly of printer, with regard to the development of printer, can be divided into impact printer, laser printer and ink-jet printer.Impact printer is eliminated because speed is slow, low precision, noise are big gradually; Still difficulty is universal very soon owing to price problem for laser printer; Color inkjet printer can be printed various exquisite colour pictures and photo, and printing precision surpasses human eye resolution ratio, and spreading speed is exceedingly fast.Ink-jet printer has become the main product of current printer market, and occupation rate of market is also the highest.Because the rise and the fast development of digital product, thereby driven the quick growth of relevant printer.
Print cartridge costs an arm and a leg as the standard running stores of ink-jet printer, if disposable use contaminated environment not only, still to the significant wastage of social resources.Refilling service industry recharges its original function of recovery for the print cartridge that uses up, and is intended to economize on resources, promote environmental protection, has also reduced the printing cost for the user.Yet a lot of print cartridges are owing to the reason in the design can't be come filling ink by hand; Even what have can fill by hand, but also can't normal printing, even can damage print cartridge shower nozzle and printer; So from using original manual refilling at first, developing into, the refilling service trade uses the refilling of special-purpose refilling equipment.Its basic principle is under the certain pressure effect, ink to be injected in the print cartridge, and the print cartridge internal pressure necessarily is in low relatively position during refilling.
Use at present refilling equipment to realize that the technology of refilling mainly contains following several kinds on the market:
1, vacuum ink feeder, the applicant applies for a patent in calendar year 2001, and the patent No. is 01267625.x.
At first, the shortcoming of this refilling method is no matter be monochrome or polychrome can not accurately setting ink injection amount under programming state, even and if under manual state to monochromatic ink setting ink injection amount also difficulty very; Existing part ink is an oily ink; Because its chemical characteristic in the time of in being inhaled into the syringe that is in vacuum state, can produce a large amount of foams; Cause the user can't see the height of ink in syringe clearly, thus can't setting ink injection amount.And when for multi-color ink; When promptly the colour ink box of two above colors being carried out refilling; Because the plastic tube length that the variant and different syringes of the meeting of the vacuum in the different syringes are connected with ink bottle differs; Can cause the quantity of ink that is inhaled in the time in the syringe in same settings variant, can't set consistent ink injection amount for, thereby cause plural colour can't set consistent ink injection amount at all.
Secondly; General Vaccum ink filler method; When confirming quantity of ink,, will cause and utilize vacuum ink to be sucked in the print cartridge process because the blocking effect of sponge if when the ink that in syringe, adds is less than the actual maximum volume of print cartridge; Ink can't arrive print cartridge shower nozzle ink outlet mouth place, thereby the print cartridge of having annotated could use after needing further to handle.If the ink that in syringe, adds is greater than the actual maximum volume of print cartridge, ink just can be full of whole print cartridge fully like this, guarantees that ink arrives the ink outlet mouth place.But in fact the standard ink capacity of all print cartridges all is less than the actual maximum volume of print cartridge; Especially the print cartridge of HP, LEXMARK; Standard ink capacity in the print cartridge is 1/2 even 1/3 of a print cartridge maximum volume; When the ink that injects surpassed the normal capacity of print cartridge design, print cartridge will can't be placed on the printer and print from the shower nozzle ink leak fully.So adopt the refilling method let ink be full of whole print cartridge fully, also must pumpback go out to exceed the ink of print cartridge normal capacity.But because the adsorption effect of sponge is often injected the ink that 10 milliliters of inks can only be drawn back the 3-4 milliliter, the ink that pumpback stays in the print cartridge when can not taking out ink still will exceed the actual standard capacity of print cartridge, still can cause ink leak, can't print.Even if for a part can pumpback to the print cartridge of print cartridge standard ink amount, when pumpback, can not measure the ink quantity of pumpback, can't set and control the quantity of ink of pumpback, can cause the quantity of ink that stays in the intact the same print cartridge box of each notes all inconsistent.So general Vaccum ink filler method is also taken out the print cartridge that is lower than the print cartridge normal capacity less than remaining ink in the box for pumpback, can't refilling, for pumpback can pumpback to the print cartridge of print cartridge normal capacity, after each refilling, ink remaining in the box all is inconsistent.
Once more, the labeling paper that traditional Vaccum ink filler method must be torn on the print cartridge air-vent spills air-vent, or opens the stopper on the print cartridge air-vent, and the refilling head is inserted air-vent, guarantees sealing, could realize print cartridge is vacuumized.This method one is to destroy the print cartridge structure, the 2nd, and the refilling head is inserted on the air-vent loosening easily gas leakage, especially three looks above print cartridge, and when 3 or 5 refilling heads are inserted on the print cartridge simultaneously, loosening more easily and gas leakage causes and can't realize Vaccum ink filler.
2, have the quantitative refilling of peristaltic pump in vacuum storehouse, in the patent of the quantitative refilling of application peristaltic pump in 2005, the patent No. is 200510013157.9 to the applicant.The shortcoming of this refilling method is:
1) print cartridge being put into the vacuum storehouse vacuumizes; Can not fully air in the sponge be taken away; Thereby cause the injection ink can not be filled to shower nozzle ink outlet mouth place fully; Need from shower nozzle arrives the nozzle place with the vacuum suction ink after, can go up the machine printing after the refilling, otherwise can not print immediately, need placement a period of time let ink under the effect of atmospheric pressure, ink moved to nozzle.
2) need tear paster on the print cartridge before the refilling, or open stopper or the ball on the print cartridge, stick a needle in the box then; Also will be after the refilling with the paster on the print cartridge, stopper or ball reduction; This process trouble, and be easy to damage the print cartridge structure, cause the print cartridge permanent damage.
3) ink-filling needle must thrust in the sponge of print cartridge, has destroyed sponge structure, and the number of times that recharges is restricted, and has reduced print cartridge and has reused the life-span.
4) ink-filling needle must thrust the print cartridge bottom during refilling, and misoperation punctures the filter screen in the print cartridge easily, causes causing the permanent damage of print cartridge because of the ink filter effect plug that descends.
5) control of peristaltic pump refilling employing time quantitatively requires the uniformity and the stability of motor, then increases manufacturing cost by this requirement.Even if adopt good again direct current generator, running time one, length also can produce the quantitative deviation of ink.
6) print cartridge greatly being arranged, is not sponge structure in the box, can't adopt the notes method that is needled in the print cartridge, has caused the refilling in this way of a lot of print cartridges.
3, malleation is from shower nozzle refilling method, and its shortcoming is:
1) only being applicable to the infusing ink in ink box that has shower nozzle, is the print cartridge of not being with shower nozzle and almost accounted for the half the print cartridge in market, can't use this method refilling.
2) print cartridge of band shower nozzle, shower nozzle is easy to stop up, in case shower nozzle stop up, from the shower nozzle refilling will be very slow, even annotate not enter fully.
3) owing to be the malleation refilling,, must improve the compressive property of related elements, parts, strengthen the device fabrication cost in order to guarantee the air-tightness of refilling pipeline.
4) precondition of malleation refilling is a not plug of print cartridge, and print cartridge is dealt with improperly in earlier stage and can not be accomplished refilling, has improved operating personnel's competency profiling undoubtedly, has increased the refilling cost of serving; Also possibly cause refilling service operator and client's responsibility simultaneously disagrees.
5) for colour ink box; Because three different colours ink nozzles concentrate in together; Implement the malleation refilling from shower nozzle and be easy to mutual colour contamination, must design and produce effective refilling anchor clamps, guarantee several kinds of colored nozzles strict differentiation under the particular area of shower nozzle isolated; Not ink leak, not colour contamination during the malleation refilling.It is bigger to implement difficulty, and manufacturing cost is high, and selling price is also high, and there is limitation in market.
6) the print cartridge nozzle can wear and tear in malleation refilling process, causes the distortion of the nozzle portion of pursuing, and causes printing effect to descend, thereby has limited the number of times that recharges.
7) be the capacity of the syringe fixed from shower nozzle refilling ink injection amount, want to change the stroke that quantity of ink must be regulated the cylinder that promotes piston that every change once all will be regulated.
In sum, all there is some defective in various degree in existing refilling equipment, not only can not accurately setting ink injection amount, can not realize the refilling of harmless fully print cartridge, and for this reason, need design can accurately control the infusing ink in ink box amount, and realize the ink-joiner of harmless fully print cartridge.

Adopt CPU and relevant control circuit selection function, control refilling process in the master control borad of the present invention, and calculate quantity of ink through the count pulse of catching near switch sensor output.The optional majority kind of this machine colour carries out refilling, and is as shown in Figure 1.Ink injection amount can enter data into through the button on the panel among the CPU, and CPU shows ink injection amount according to the data of input on LCD, and calculates corresponding count pulse number.After vacuumizing end; By the panel button of " going into China ink ", peristaltic pump starts, and the black magnetic valve 11 of going into that is connected in series with it is opened; Ink sucking-off from ink bottle is injected in the China ink amount display tube 12; Peristaltic pump is closed when CPU detects the corresponding count pulse of setting ink injection amount and counts, and the black magnetic valve of going into of serial connection also is closed, and the ink that injects display tube this moment is exactly the quantity of ink of setting.Press " refilling " key on the panel again, the ink in the display tube is injected in the print cartridge.
As shown in figures 1 and 3, according to above-mentioned part, the present invention is provided with ten two road peristaltic pumps; Control the ink of 12 kinds of colors respectively; Its way can increase or reduce according to the actual requirements, and Fig. 3 only provides one tunnel work structuring figure, and Fig. 4,5,6 only provides a kind of print cartridge anchor clamps sketch map; Other model print cartridge anchor clamps are just different according to the position in print cartridge size and print cartridge air intake duct hole, adjust the design size of a lower clamp each several part slightly.Described print cartridge anchor clamps comprise silica gel poppet 13, silicagel pad 14, cartridge carrier 15 and pressing tongs 16, and silica gel poppet, cartridge carrier and pressing tongs are fixed on the anchor clamps base plate 17 successively.Wherein, Silicagel pad is contained on the silica gel poppet, and silicagel pad is provided with the silicagel pad air gap 18 and silicagel pad leadout hole 19 of corresponding each print cartridge air intake duct Position Design, and the silicagel pad air gap is closely corresponding with the print cartridge air intake duct; The silicagel pad leadout hole is positioned at silicagel pad air gap place; Run through silicagel pad, be used for the refilling head insertion of refilling pipe end can be realized being tightly connected of pipeline and print cartridge air intake duct, the end of pressing tongs is equipped with shower nozzle sealing rubber pad 20.Before the refilling; Print cartridge 30 that will refilling is put into the cartridge carrier of print cartridge anchor clamps; Last pushing pincers clamp print cartridge, air flue place face and the tight crimping of silicagel pad on the print cartridge, and gas port communicates with corresponding silica gel cushion steam crack; Be connected rubber blanket and the 31 tight crimping of print cartridge shower nozzle on the pressing tongs push rod, guaranteed that the print cartridge nozzle is sealed.To measure the refilling head made from nylon material that display tube draws with China ink and insert in the leadout hole of silicagel pad, print cartridge just is connected with the refilling line seal like this.Print cartridge anchor clamps base plate is fixed on the body.
As shown in Figure 9, after refilling of the present invention is accomplished, print cartridge is put into the cartridge carrier 23 of installing on the centrifuge rotating disk 22 of centrifuge 21; Cover the centrifuge loam cake; Carry out centrifugal treating, described centrifuge 700-2500 rev/min, ink is moved to shower nozzle ink outlet mouth place.Sewer pipe 35 discharge centrifuges that waste liquid connects through centrifuge rotating disk below.
As shown in figures 1 and 3; Refilling system vacuum pump of the present invention 25, positive and negative pressure main valve 26,27, surge tank 31, waste liquid tank 24 connect successively; Pressure gauge 28 is connected with surge tank through the gas outlet of air valve 29; The waste liquid tank top also connects vent valve 32 respectively, takes out waist valve 33, and the below connects removal waste fluid valve 34.When vent valve was opened, atmosphere got into waste liquid tank, under the atmospheric pressure effect, the ink in the display tube is pressed in the print cartridge of being pumped into negative pressure state.Take out when waist valve is opened and under the effect of negative pressure source of the gas, the remaining ink in the print cartridge is extracted out in the entering waste collection device, so that print cartridge injects new ink.When the discarded ink in the waste collection device reached setting height, CPU detected automatic discharging signal, opened the removal waste fluid valve and will discard the ink discharge.
The course of work of the present invention is following:
Open the power supply of ink-joiner, display screen is with the display reminding picture, and the operator only needs to operate according to the picture prompting.Select ink pipeline and corresponding refilling anchor clamps according to the print cartridge brand and model, print cartridge is placed on the anchor clamps of selection and locks, and the refilling head of selected ink is inserted in the corresponding aperture on the anchor clamps.According to picture prompting setting ink injection amount, by " vacuum " key, begin to vacuumize, the air in the print cartridge is extracted out; When system pressure table indicated value reach-below the 0.1MPa, and when not had bubble in the print cartridge and emerging, by " going into China ink " key, the magnetic valve of peristaltic pump and serial connection starts, ink is pumped into China ink and is measured in the display tube by set amount; Go into China ink and stop the back by " refilling " key, ink promptly is injected in the print cartridge.Take off the print cartridge of refilling from anchor clamps, put into special centrifugal machine and start centrifuge, the ink that injects is moved to the shower nozzle of print cartridge.The print cartridge that takes out after centrifugal can use on the machine.
As shown in Figure 3, provide the fundamental diagram of the ink-joiner first via, the refilling course of work is:
(1) print cartridge that will refilling is put into the refilling anchor clamps like diagramatic way after doing to annotate pre-treatment, and last pushing force clamps print cartridge is clamped.Air flue place face and the tight crimping of silicagel pad on the print cartridge, gas port communicates with corresponding silica gel cushion steam crack; Be connected rubber blanket and the tight crimping of print cartridge shower nozzle on the pressure clamp push rod, guaranteed that the print cartridge nozzle is sealed.
(2) will measure the refilling head made from nylon material that display tube 1 links to each other with China ink and insert in the leadout hole of silicagel pad, print cartridge just is linked to be a system with the refilling pipeline like this.
(3) open system power supply, by " vacuum " button, vavuum pump starts; Malleation main valve in the system cuts out, and the negative pressure main valve is opened, and air valve 1 is opened; Other closed electromagnetic valves; Along with the operation of vavuum pump, the air in the print cartridge is drawn out of, and arranges in atmosphere through the gas outlet of China ink amount display tube, air valve 1, waste liquid tank, surge tank, negative pressure main valve, vavuum pump, malleation main valve.Pressure gauge is connected with surge tank through the gas outlet of air valve, the pressure of indication pipe-line system.When the Pressure gauge indicated value reach-during 0.1MPa, the air in the print cartridge seldom, when no bubble is emerged in the print cartridge of delaying time till.
(4) once more by " vacuum " button, finish to vacuumize, by " going into China ink " button, vavuum pump is out of service, closes the negative pressure main valve, opens peristaltic pump delivery port China ink valve, moves peristaltic pump simultaneously, and other magnetic valve hold modes are constant.Ink in the ink bottle is drawn under the effect of peristaltic pump in the China ink amount display tube.It is corresponding with the roller end face in the peristaltic pump near the probe of switch to be installed on the peristaltic pump end face inductance; Peristaltic pump constantly rotates, and its roller end face is constantly relative near the probe of switch with inductance, whenever relatively once; Because the effect of eddy current; Inductance near the oscillating circuit in the switch once and send a pulse signal and received by counter with regard to failure of oscillation, when the ink injection amount of count value and setting was suitable, peristaltic pump was just out of service under the control of single-chip microcomputer; Coupled air valve 1 is also closed simultaneously, goes into China ink and finishes.
(5) by " refilling " key, peristaltic pump delivery port China ink valve is closed, and vent valve is opened, and other magnetic valve hold modes are constant, and refilling starts, and under the atmospheric pressure effect, the ink in the China ink amount display tube is injected in the print cartridge.
(6) open pressure clamp, take off print cartridge from anchor clamps, refilling finishes.
(7) print cartridge after the refilling is put into special centrifugal machine and is carried out centrifugal treating.
