When upper, cleaning solution is gradually flushed away, and carries out the removal of cleaning solution, and only pure water remains in the surface of anilox roll 1.
Pure water when the above-mentioned pure water for being mixed into cleaning solution and cleaning are completed is arranged on anilox roll 1 as described above
The pallet 19 of lower section receives.
(5) removal of the pure water in anilox roll 1 and the drying of anilox roll 1
At this moment, become the state for being only attached with pure water as described above on the surface of anilox roll 1.As the state
Moment carries out the removal of the pure water of anilox roll 1 and doing for anilox roll 1 using the drying section 7 for the surface for being arranged on anilox roll 1
It is dry.
In the shell 7a for forming drying section 7, the compressed air of high pressure is sprayed from the ejiction opening 7b in upstream side or center, it will be high
On the blast injection of pressure to the surface of the anilox roll 1 for the opposite face for coming shell 7a.
The compressed air of above-mentioned high pressure vibrates ridge 7e in the narrow high frequency generating unit 13 of ejiction opening 7b, thus with height
Frequency generates the power of air drag.The vibration of the high frequency is Chong Die with the ejection air that blowing loophole 7b sprays, which sprays empty
Gas does not only reach to the surface of anilox roll 1, the bottom of even up to countless micro hole 1a, by the surface of anilox roll 1 and entrance
It is blown away to the pure water in micro hole 1a.The signal of the effect of the high-frequency compression air of the high pressure is represented in the enlarged drawing of Fig. 4
Situation.
The pure water blown away becomes fine drop in small gap 16 and disperses around, but due in ejiction opening
7b into side in a manner of from sandwich ejiction opening 7b (or in downstream side), be provided with the attraction towards ejiction opening 7b side openings
Mouth 7k, so above-mentioned fine droplets are directly inhaled into suction port 7k.
In this case, since the attraction air capacity of suction port 7k is set as bigger than the air capacity from ejiction opening 7b,
So negative pressure is in compared to external around suction port 7k.Therefore, fine droplets will not fly out from small gap 16.
The fine droplets being inhaled into pressure reduction space are fed to by decompression piping 11 in gas-liquid separation device 12, micro-
Small droplet falls and is trapped in the bottom of gas-liquid separation device 12, and air passes through pressure by separation and after being filtered by filter 12f
The attraction of contracting machine 17 and be pressed into pressurization piping 10 in.
Also, it is fed again into the pressurization space 7c of the shell 7a of drying section 7 and is sprayed from ejiction opening 7b.
Such operation is repeated, much less the pure water on the surface of anilox roll 1, the pure water in micro hole 1a can also be blown
It runs, the drying of anilox roll 1 terminates.
In addition, in the above cases, the air for being mixed into fine droplets is detached using gas-liquid separation device 12, to dividing
Air from after carries out cycling and reutilization, but can also be as shown in (b) of Fig. 2, without using gas-liquid separation device 12, by air blast
Air after separation is directly discharged in factory's exhaust pipe by machine 18.
