Make the cavity seat that interlocks, cone structure is made in cavity seat bottom, and matched valve core of the electromagnetic valve head is made ball structure, adopted
Use 316 stainless steel materials.This rigid structure sealing means, overcome the varying dimensions of flexible material (elastomeric material).Avoid
The change in solenoid movement space in jet printing process causes the change of spray printing effect, makes spray printing sizes of ink dots more balanced steady
It is fixed.
2nd, staggered cavity body structure
Intersecting shape is intersected into cavity with each electromagnetic valve cylindrical hole by cavity cylindrical hole, ink in cavity, can be accommodated, it is empty
Chamber is also ined succession electromagnetic valve, and valve core of the electromagnetic valve spheroid blocks the conical surface of cavity bottom, and drive circuit drive magnetic valve is for linear motion,
So as to form switch valve events, ink-jet function is realized.Cavity solenoid carries out spatial intersecting arrangement, selects for different ink
With power electromagnetic valve of different sizes.
3rd, venting pipeline, venting pipeline single-pass closed electromagnetic valve during work are set.Because paint ink occurs deposited phenomenon,
When shutdown is not used, ink is detained in pipeline for a long time and ink deposition just occurs, therefore controller starts cleaning side when shutting down
Formula, ink feed pipeline automatically switch to abluent pipeline by three-way magnetic valve, and now venting pipeline single-pass electromagnetic valve is opened, pipeline
Rinse well by abluent with inside shower nozzle.
4th, aircleaning facility, to guarantee the long-term normal work of shower nozzle, avoids prepared Chinese ink residual from bleeding back after being cleaned with abluent
To on nozzle, jet-printing head nozzle is also provided with aircleaning facility, and when abluent is cleaned, controller starts aircleaning facility,
The pressure air of 0.5Mpa is filled with jet-printing head nozzle surface, and nozzle is blown clean.
5th, electromagnetic valve air-cooling apparatus, produces fever phenomenon during because of great-power electromagnetic valve high-speed cruising, is provided with air
Chiller, when shower nozzle works, electromagnetic valve is opened, and pressure air sprays to electromagnetic valve coil surface by air-cooling apparatus air,
Accelerate cross-ventilation and improve cooling effect.
The present invention operation principle be：
1st, peripheral control unit is transferred to corresponding shower nozzle electromagnetic valve by 37 core Aviation Connector drive signals, performs shower nozzle electricity
The action of magnet valve Push And Release, when shower nozzle electromagnetic valve is opened, staggeredly the pressure ink in cavity seat is sprayed along jewel nozzles,
The body surface of motion forms dot matrix character.
When jet-printing head works, pressure ink staggeredly in cavity seat, is always maintained at, pressure ink is connect by the first dividing plate
Head connection Φ 6PA ink inlet tubes enter staggeredly cavity seat and are full of inner chamber to the first bent sub, and Jing the second bent subs flow backward through Φ
6PA ventings pipe flow to second partition joint enters outside interval cut-off equipment and returns to ink barrel, makes ink intermittent cyclic work always
Make, it is ensured that ink is not precipitated.Air-cooling apparatus work while jet-printing head works, outside cooling gas are connect by the 5th dividing plate
Head, connects 6 trachea Jing pagoda joint air inlet chillers of Φ, constantly cold air is blown in shower nozzle electromagnetism valve surface, carried out
Shower nozzle electromagnetic valve radiates.
2nd, at the end of spray printing, jet-printing head carries out internal washing process.
Cleanout fluid connects Φ 6PA ventings pipes by outside three-way magnetic valve Jing second partitions joint and enters to the second bent sub
Staggeredly cavity seat, then flow to Φ 6PA the first dividing plates of ink inlet tube Jing joint to the first bent sub and enter outside three-way magnetic valve row
Enter clean and reuse bottle.When cleanout fluid is full of staggeredly cavity seat inner chamber simultaneously, host driven shower nozzle performs cleaning procedure, cleanout fluid
Prepared Chinese ink in nozzle bore is rinsed well.After the completion of nozzle rinse, start nozzle dry up program, now pressure-air by the 3rd every
Plate joint enters single channel electromagnetic valve, and pressure air dries up nozzle into nozzle chambers to Jing three way cock all the way, leads up to 6 tracheas of Φ
The 4th dividing plate joints of Jing are to exterior operator.
Wherein, the operation principle of electromagnetic valve is：When external drive voltage is loaded into inductance coil, inductance coil produces magnetic
, the spring force of 316 heterotypic springs is overcome by magnetism intensity, pull valve element (valve element, nonmagnetic set, without magnetic ball seat and ball
Coupled using interference fit), valve element action.The magnetic line of force then N levels and S are produced during inductance coil lead end generating positive and negative voltage alternate
Level also alternate, so that valve element does straight line back and forth movement.Regulation stroke ranges of the S in Fig. 5 for adjusting spool.
In a word, the present invention is that one kind is interlocked by electromagnetism valve position, changes nozzle spacing, while controller need not be changed
Control mode, directly can be controlled using control system in the market, make nozzle structure simpler, easy to maintenance.Nozzle spacing
Can be changed by the change of cavity electromagnetic valve position, as long as changing the height that cavity this accessory can easily realize spray printing font
Degree, it is with low cost, it is simple to operate.
Although the foregoing describing the specific embodiment of the present invention, those familiar with the art should manage
Solution, the specific embodiment described by us are merely exemplary, rather than for the restriction to the scope of the present invention, are familiar with this
The technical staff in field should be covered the present invention's in the equivalent modification and change made according to the spirit of the present invention
In scope of the claimed protection.
