The specific embodiment:
See Fig. 1-shown in Figure 3, present embodiment includes anilox roll 1, nylon end shrouding 2, elastic ends shrouding 3, single scraper China ink chamber 4, spring block 5, spring 6, spring pull bar 7, air bag 9, scraper 10, pad 11, pressing plate 12, linkage 13, screw 14, single scraper China ink chamber 4 is installed on the support 8 by linkage 13, single scraper China ink chamber 4 can be rotated around the axis of linkage 13, and scraper 10 and pad 11 are fixed on single scraper China ink chamber 4 by pressing plate 12, screw 11; Spring block 5 is fixed on the support 8, one end of spring pull bar 7 has screw thread, the other end of spring pull bar 7 is a plate-like shaft shoulder, and the end of thread of spring pull bar 7 is installed in the screw in single scraper China ink chamber 4, and spring 6 is installed between the plate-like shaft shoulder of spring block 5 and spring pull bar 7; Nylon end shrouding 2, elastic ends shrouding 3 are installed in the two ends in single scraper China ink chamber respectively, elastic ends shrouding 3 compressible distortion and being close on the surface of anilox roll 1; Single scraper China ink chamber 4 and scraper 10, nylon end shrouding 2, elastic ends shrouding 3 when elastic ends shrouding 3 clings to anilox roll 1 surperficial, form one and contain black chamber; Air bag 9 is installed between single scraper China ink chamber 4 and the support 8.Air bag 9 is a monoblock type strip, and end sealing, an end are provided with the bag type paste structure of inflation inlet,, bag material is a rubber, the inflation back is inflatable, is returned to former state after the venting.
Operation principle of the present invention is: produce behind airbag aeration and expand, promoting single scraper China ink chamber rotates around the axis of linkage, air bag shifts single scraper China ink chamber near anilox roll onto, the elastic ends shrouding at first touches the surface of anilox roll and is compressed, till nylon end shrouding touches the anilox roll surface, scraper will be close on the surface of anilox roll this moment, form one by the space after scraper, single scraper China ink chamber, nylon end shrouding, elastic ends shrouding, the anilox roll combination and contain black chamber (see figure 1).At air bag single scraper China ink chamber is shifted onto near in the process of anilox roll, spring gives single scraper China ink chamber a reversal interlocking relay by spring block, spring pull bar, making air bag reach certain pressure could push away single scraper China ink chamber forward, the pressure of air bag just can be even like this, and the thrust that makes single scraper China ink chamber push away forward is even equally.Rotate to the direction of leaving anilox roll by the pulling force of spring in single scraper China ink chamber after the air bag release, thereby make scraper, nylon end shrouding, elastic ends shrouding leave the anilox roll surface.
When machine works, air bag shifts single scraper China ink chamber near anilox roll onto, elastic ends shrouding, nylon end shrouding, scraper are close to form on the anilox roll contains black chamber, the ink feeding system of machine pumps into black chamber with ink, ink has a stop of short duration in black chamber, ink is capable of circulation to the anilox roll inking, flows into the ink reclaiming pipe of ink feeding system then, gets back to the China ink bucket.Scraper is close to the surface of anilox roll when machine works, make the even inking of anilox roll, paste the fine granularity object that is had in the lip-deep dust in air of anilox roll and the dust, can be scraped by scraper and fall in the ink, flow back to the China ink bucket with ink, because of ink feeding system has filter, the fine granularity object that flows back to the China ink bucket will be filtered, and not scratch so can not produce anilox roll.Because elastic ends shrouding, nylon end shrouding, scraper are close to the black chamber of formation Sheng on the anilox roll, ink flows into the China ink bucket through ink reclaiming pipe, rather than connects disc from the two ends inflow of anilox roll and scraper, so can not pollute machine and place generation.After print job is finished, a certain amount of clear water injected contains black chamber,, can the surplus China ink on the anilox roll be cleaned because the clear water that injects has a brief stay containing black chamber equally, thus the time to contain the China ink amount in the water that cleans higher, can recycle.After cleaning through the first round, surplus China ink reclaims substantially on the anilox roll, and then during cleaning anilox roller, contains the China ink amount in the water of cleaning and reduce greatly, can save water for cleaning, reduces and cleans the pollution that brings, the cost of reduction water treatment.
