Abstract
The utility model relates to a kind of nozzle ink chamber runner inner circulation structure of pressure-adjustable, comprise head body, ink inlet tube, circulation pipe, main black chamber, pressure chamber, several spray orifice, pump, degasser, pressure sensor and controller, described main black chamber is connected with pressure chamber, described spray orifice is opened in bottom pressure chamber, described pressure sensor is arranged in ink inlet tube, and described controller is connected with pressure sensor, pump respectively.The utility model reasonable in design, dependable performance, can control the force value needed at, and realize the full flowing Inner eycle of ink in black chamber, substantially increase shower nozzle stream time, reduce the maintenance cost of shower nozzle by ink delivery pressure.
Description
Technical field
The utility model relates to a kind of shower nozzle of ink-jet printer, especially relates to a kind of nozzle ink chamber runner inner circulation structure of pressure-adjustable.
Background technology
Easily there is the situation that spray orifice blocks in shower nozzle conventional in now widely used ink-jet printer, such as spray orifice is easily by the blocking such as bubble, impurity, and shower nozzle is once blocked, will affect the normal operation of printer, reduces the quality of production of printed product.In actual use, spray orifice, once there is the situation of blocking, just needs the operation stopping shower nozzle, and dredging spray orifice, reduces operating efficiency on the one hand, too increases workload on the other hand.
Modern industry shower nozzle all adopts the working method of " need based jet ".When not receiving jeting instruction at ordinary times, shower nozzle does not spray ink droplet, but relies on the pressure differential between therein and outside atmosphere, ink is remained on spray nozzle inside; When shower nozzle receives the instruction needing to spray ink droplet, namely produce a pressure wave in inside and some inks in spray orifice are ejected; When pressure wave disappears, equally due to the effect of external and internal pressure difference, excess ink is still retained in shower nozzle, until receive next jeting instruction.Must ensure the pressure differential having a relative constancy between shower nozzle internal ink and outside atmosphere as can be seen here, this pressure differential is produced by the ink feeding system of shower nozzle.If the pressure of ink feeding system is too high, then after shower nozzle internal pressure ripple disappears, ink can not remain in shower nozzle to continue to spray and flow out even continuously, causes that print quality is inferior even scraps; If the pressure of ink feeding system is too low, then the pressure wave of shower nozzle inside can not overcome external and internal pressure difference, then ink cannot eject, and causes printing occurring blank.
On pottery, spray printing pattern can use ceramic ink, and so-called ceramic ink is exactly the suspension or the emulsion that contain certain special ceramics powder, generally includes ceramic powder, solvent, dispersant, bonding agent, surfactant and other auxiliary material.The dispersiveness of ceramic ink is bad, in use needs ink to remain on flow regime, and not so ink there will be lamination, and technical staff has made shower nozzle ink entrance into ink outlet port, makes ink in the flowing of shower nozzle inner loop, as shown in Figure 1.Although ink starts flowing, but be not that all inks in shower nozzle all start flowing, design due to the runner of shower nozzle own causes flowing can only flow in main black chamber, ink in the pressure chamber be connected with spray orifice can't flow completely, so ceramic powder still can be deposited in pressure chamber, accumulate over a long period and will change volume in pressure chamber or retaining pressure chamber completely.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in prior art, the black chamber runner inner circulation structure of the pressure-adjustable providing a kind of ink entirely can flow in nozzle ink chamber, ink delivery pressure is controlled the force value needed at, and make ink realize Inner eycle in pipeline, effectively prevent spray orifice from blocking.
A kind of nozzle ink chamber runner inner circulation structure of pressure-adjustable, comprise head body, ink inlet tube, circulation pipe, main black chamber, pressure chamber, several spray orifices, pump, degasser, pressure sensor and controller, described main black chamber is connected with pressure chamber, described spray orifice is opened in bottom pressure chamber, described pressure sensor is arranged in ink inlet tube, and described controller is connected with pressure sensor, circulating pump respectively.
As preferably, described main black top of chamber is provided with ink inlet and loop exit, and described ink inlet is connected with ink inlet tube, and described loop exit is connected with circulation pipe.
As preferably, described circulating pump is arranged on described circulation pipe, and described circulation pipe is connected with ink inlet tube.
As preferably, described degasser is arranged in ink inlet tube, and described degasser is between ink inlet tube and circulation pipe.Described degasser effectively can remove the bubble of the ink entered in main black chamber, prevents spray orifice by the situation of gas bubble blockage, improves the overall performance of shower nozzle.
The utility model reasonable in design, dependable performance, can control the force value needed at, and realize the full flowing Inner eycle of ink in black chamber, greatly reduce the precipitation probability of ceramic powder, improve the service life of shower nozzle by ink delivery pressure.Because achieve the flowing of whole ink in black chamber, the impurity causing spray orifice to block in ink and bubble also can be pulled away because of flowing, substantially increase shower nozzle stream time, reduce the maintenance cost of shower nozzle.
Accompanying drawing explanation
Fig. 1 is a kind of nozzle ink chamber runner inner circulation structure schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, a kind of nozzle ink chamber runner inner circulation structure, comprise head body 1, ink inlet tube 2, circulation pipe 3, main black chamber 4, pressure chamber 5, several spray orifices 6, circulating pump 7, degasser 8, precision pressure sensor 9 and controller 10, described main black chamber 4 is connected with described pressure chamber 5, described spray orifice 6 is opened in bottom described pressure chamber 5, described precision pressure sensor 9 is arranged in described ink inlet tube 2, and described controller 10 is connected with circulating pump 7 with described precision pressure sensor 9 respectively.
Top, described main black chamber 4 is provided with ink inlet and loop exit, and described ink inlet is connected with described ink inlet tube 2, and described loop exit is connected with described circulation pipe 3.
Described pump 7 is arranged on described circulation pipe 3, and described circulation pipe 3 one end is connected with described ink inlet tube 2.Described degasser 8 is arranged in described ink inlet tube 2, and described degasser 8 is between described ink inlet tube 2 and circulation pipe 3.
Operation principle: during the work of a kind of nozzle ink chamber runner inner circulation structure, ink passes into ink inlet tube 2, degasser 8 carries out degassed process to the ink passed into, ink enters main black chamber 4 by ink inlet tube 2, be diverted to each pressure chamber 5 again, then spray from corresponding spray orifice 6 as required, unnecessary ink continues outflow pressure chamber 5, circulating pump 7 work makes unnecessary ink realize Inner eycle by circulation pipe 3, achieves the full flowing of ink in the runner of nozzle ink chamber.In the whole course of work, be arranged on the ink pressure in precision pressure sensor 9 testing pipes in ink inlet tube 2, and transfer to controller 10, controller 10 have employed negative feedback control principle, again by Signal transmissions to circulating pump 7, the running speed of controlled circulation pump 7, makes the pressure in ink inlet tube 2 and circulation pipe 3 maintain the stationary value of needs.
