得ることを目的とする。In the conventional liquid jet nozzle, the valve for operating the jetting / stopping of the liquid is provided at a position apart from the jet port toward the injection port, although it is small. Therefore, when the ejection of the liquid is stopped, a small amount of the liquid is stored between the valve and the ejection port that are separated from each other, and the small amount of the stored liquid is directed downward from the ejection port. Dropped from the ejected liquid nozzle. For this reason, when the conventional liquid jet nozzle is used, a spot is formed by the dripping liquid on the surface of the material onto which the liquid is sprayed and uniformly attached, or around the material to which the liquid should not be attached. Therefore, it is an object of the present invention to obtain a liquid ejection nozzle in which the liquid does not drip even if only slightly even when the ejection of the liquid is stopped.

It will be ejected from inside 7. Therefore, when the gas injected into the second hermetic chamber 31 is ejected from the ejection port 13 when the liquid is ejected from the liquid storage chamber 11, the liquid can be atomized by the gas, and When the gas injected into the second hermetic chamber 31 is ejected from the ejection port 13 when the ejection of the liquid from the liquid storage chamber 11 is stopped,
The gas sent out from the second hermetic chamber 31 blows off the liquid stored in the ejection port 13, thereby preventing the liquid from dripping from the ejection port 13.

以下の〔発明の効果〕の欄において説明する。The fluid is press-fitted into the first airtight chamber 21 and the valve 1
When the moving partition wall 24 is moved in a direction in which 9 moves away from the ejection hole 13, the fluid in the auxiliary hermetic chamber 25 is injected into the injection port 26.
It is also possible to discharge the fluid from the movable partition wall 24 so that it can be easily moved.
In order to move the moving partition wall 24 in the direction in which the valve 19 is discharged toward the ejection hole 13 from the above, the fluid is pressed into the auxiliary hermetic chamber 25 through the inlet 26 to facilitate the movement of the moving partition wall 24. The coil spring 27 that pushes back the moving partition wall 24 is not always necessary when the fluid is positively pressed into or discharged from the auxiliary airtight chamber 25. Since the first airtight chamber 21 constitutes an air cylinder or a hydraulic cylinder as described above, the fluid injected / exhausted into the first airtight chamber 21 may be gas or liquid. Further, the fluid injected into and discharged from the second hermetic chamber 31 may be gas or liquid, and the reason for this will be described in the section of "Effects of the Invention" below.

The ink coating film applied to the peripheral surface of the fan ten roll 44 by 3 is transferred and supplied from the ink form roll 48 to the plate cylinder 42 via the kneading rolls 45, 56 and 47.
Reference numeral 49 is an ink feeding roll which is axially supported by an intermittently swinging arm and supplies ink from the fan roll 44 to the kneading roll 45 at any time. Reference numeral 50 denotes an ink discharge nozzle, which is carried by a carrier 52 that moves on a rail 51 over the entire width of the offset printing machine 41, and ink is gradually added according to the thickness of the ink coating film on the peripheral surface of the kneading roll 45. It is supplied to the roll 44. The nozzle 39 according to the present invention is mounted on the same carrier 52 as the ink discharge nozzle 50, and jets and supplies the organic solvent of the cleaning liquid to the fan ten roll 44 at the time of roll cleaning when printing is completed and ink is switched. Nozzle 39 according to the present invention
Like the ink discharge nozzle 50, is mounted on the carrier 52 with the tip of the nozzle facing downward. Reference numeral 53 is a cleaning doctor for collecting dirty cleaning liquid adhering to the peripheral surface of the fan roll, which is pushed out by the air cylinder 56 and comes into contact with the peripheral surface of the fan roll 44 only when cleaning the roll. ing. Reference numeral 54 is a pad for collecting drainage, and 55 is a hose for discharging drainage from the pad 54.

Since the liquid is pushed out from the inside of the liquid storage chamber 11 and fitted into the ejection port 13 and comes into close contact with the peripheral edge 17 of the ejection port to stop the ejection of the liquid, the liquid does not stay at the ejection port 13 at that time. Therefore, even if the nozzle 39 is mounted on the fan roll as a cleaning liquid jet nozzle of the printing machine with the mouth facing downward, the cleaning liquid carelessly drops from the mouth to the fan roll and mixes with the ink. There is no such thing as a trouble.
