Description
Technical field
The utility model belongs to industrial inkjet printing device (as advertising painting machine, digital decorating machine etc.) technical field, particularly relates to a kind of spray nozzle dual-purpose apparatus.
Background technology
Ink jet printing device shower nozzle used is core apparatus, and ink droplet is correctly ejected on print media by the effect of shower nozzle exactly, and therefore the print quality of the equipment state of just spraying ink droplet with shower nozzle is closely bound up.
Modern ink jet printing device, the mode of general employing negative pressure pump, implementation is as follows: be communicated on a negative pressure pump by assorted negative pressure ink bottle, and on pipeline, arrange a pressure switch, is decided the switch of negative pressure pump by the pressure bound in the pressure switch of setting; Namely, when the maximum pressure that black bottle ink delivery pressure sets higher than pressure switch, start negative pressure pump and extract the air in black bottle out a part, the pressure in black bottle is reduced; When the minimum pressure that black bottle ink delivery pressure sets lower than pressure switch, close negative pressure pump.Due to negative pressure pump discontinuous under this kind of mode, be unfavorable for that pressure keeps, therefore also some mode adopts the mode of overflow, i.e. an overflow valve in parallel with negative pressure pump, and negative pressure pump often goes into operation the switch of work, the overflow valve of the bound that pressure switch sets decision.
In addition, shower nozzle, except will correctly spray except ink droplet, also needs to clean once there is blocking; Existing shower nozzle cleaning technique generally adopts shower nozzle special cleaning injection nozzle, the granule after dry solidification is gone out spray orifice to ensure that shower nozzle is inner clear and coherent without residual ink.
Existing scheme is present in some problems:
One is Stress control inaccuracy.The pressure controling precision of this mode is that the bound that set by pressure switch determines, in fact in negative pressure ink supply situation, shower nozzle is not under the pressure being operated in a relative constancy, but does not stop to change back and forth within the scope of the bound set at this; So in fact, the droplet size that shower nozzle sprays can not accurately control, and can change very unbalanced suddenly big or suddenly smallly, print quality will be caused like this to decline.If the range set of downforce up and down of pressure switch is obtained narrow, although control accuracy improves, because performer switch is too frequent, will soon damages and therefore not there is practicality.
Two is pressure transients.Because air has certain elasticity, when each switch pump or overflow valve, all can produce a larger pressure crest or trough, sometimes even can exceed operating pressure at sprinkler scope, be easy to cause sprinkler pressure too high, time serious, directly can damage shower nozzle.
Three is that stable-pressure device and cleaning device separate, and there is very large inconvenience during use.Often need shower nozzle to take apart cleaning when carrying out cleaning treatment to shower nozzle, add action and also reduce operating efficiency.
Summary of the invention
For solving the problem, the utility model provides a kind of spray nozzle dual-purpose apparatus, the stable-pressure device of shower nozzle and cleaning device is set to one.
A kind of spray nozzle dual-purpose apparatus, described device comprises vavuum pump, controller, pressure sensor, surge flask, vacuum generator, solenoid directional control valve, pipeline and shower nozzle, described pipeline is divided into main line and two branch pipeline, described controller respectively with pressure sensor, solenoid directional control valve is connected with vavuum pump, described pressure sensor is located on described main line, described solenoid directional control valve connects vavuum pump and described two branch pipeline respectively, wherein a branch pipeline is provided with surge flask, vacuum generator and check valve, described branch pipeline another be connected directly to main line.
As preferably, an interface of described pump communicates with the external world.
As preferably, described shower nozzle comprises a negative pressure ink bottle and a spray orifice, and described negative pressure ink bottle is provided with one and leads to extraneous pipeline.
As preferably, described surge flask quantity is two, and the exhaust outlet of described vavuum pump is connected with a surge flask long tube mouth, and this surge flask short tube mouth is connected with the air supply opening of described vacuum generator; The vacuum port of described vacuum generator is connected with another surge flask short tube mouth, and this surge flask long tube mouth is connected with main line.
As preferably, described solenoid directional control valve is two-bit triplet solenoid directional control valve.
