The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Operation principle of the present utility model is, adopts unique chamber structure and the design of double-deck envelope China ink, and the inking effect is better, more can save printing ink; Control a large amount of volatilizations of solvent in the printing ink effectively, improved working environment, reduced air pollution.Because most of zone at printing ink place all seal, have only outside the minimum part that contacts with anilox roll is exposed to, so significantly reduced the volatile quantity of solvent.
Ink system is scraped in the utility model sealing, removed traditional last black rubber roll, ink fountain, use novel closed cavity instead, closed cavity is provided with up and down the sealing block at two doctor blades and two ends, by pump China ink is passed in the reticulate pattern drop roller, and surplus China ink is back to China ink bucket by the ink reclaiming pipe road, form circulation and give China ink, closed cavity makes it fully contact with the ink transfer anilox roll by pneumatic or hydraulic pressure, and corresponding regulating system is arranged.
As shown in Figure 1, it is the preceding TV structure of rotating shaft part of the present utility model, chute 1 level is installed on two sidewall panels 11, be provided with a slide block 2 in every limit chute 1, slide block 2 moves horizontally in chute 1, rotating shaft core a4 is installed on the slide block 2 of one end, rotating shaft core b9 is installed on the slide block 2 of the other end, rotating shaft core a4 and rotating shaft core b9 are fixed together by screw 5 and slide block 2 respectively, one end of rotating shaft 6 is provided with tightening handle 3, be used for preventing after cavity is adjusted rotation, the other end of rotating shaft 6 is provided with fastening handle 7, and rotating shaft 6 is connected with rotating shaft core b9, prevents that rotating shaft 6 is traversing, the outside of rotating shaft 6 is installed with connecting plate 16, and connecting plate 16 is fastened in the rotating shaft 6 by tightening handle 3.7 fix an end expand axle 9 and rotating shaft for spanner, prevent that rotating shaft 6 from laterally moving, and 3 rotate for the tightening handle rear defence spline axle 6 that is used to adjust to the right place.
As shown in Figure 2, black groove of the present utility model adopts the totally enclosed type form, comprise that enclosed cavity 15 is connected with connecting plate 16, the upper end of enclosed cavity 15 is connected with pressing plate 14 by several bridge screws 13, accompany doctor blade 12 between the inclined-plane of pressing plate 14 and enclosed cavity 15, the also the same doctor blade 12 that is symmetrically installed with in the lower end of enclosed cavity 15 with last end structure.Are furnished with two doctors up and down in the groove, the doctor blade 12 of upper end is secondary scraper, mainly seal, the doctor blade 12 of lower end is main scraper, play the wiping effect, can adapt to the requirement that still can keep anilox roll 17 constant inkings in the ink transfer of modern flexo high speed, the splash phenomena when having got rid of high-speed cruising.When changing doctor blade 12, put into doctor blade 12, push down, note edge of a knife installation direction, and clam member screw 13 with pressing plate 14, must begin from middle screw when noting trip bolt fastening to two ends respectively, smooth with the assurance blade.
As shown in Figure 2, when the utility model uses in work, whole enclosed cavity 15 is pressed close to the roll surface of anilox roll 17, and be in contact with one another with doctor blade 12 up and down, tighten then and connect handle 29, connect handle 29 and be used for being connected between cavity and the rotating shaft, 6 move or rotate around the shaft to prevent enclosed cavity 15; Connect the pipe that advances China ink and ink outlet port of enclosed cavity 15 centres.After treating anilox roll 17 normal rotation, start ink pumps and begin ink supply, observe the black situation of envelope, adjust pressure adjustment screw 24 by regulating, suitably increase or reduce the pressure of 12 pairs of anilox roll 17 of doctor blade up and down according to actual conditions.Generally speaking, doctor blade 12 is higher to the pressure of anilox roll 17 up and down during startup, adjusts pressure by pressure adjustment screw 24 then.
As shown in Figure 3, the utility model chute 1 is provided with a gas strut 19, the same end that wraps in the indent 18 of gas strut 19 outsides is connected with chute 1 simultaneously, the other end of gas strut 19 is connected with pushing block 20, pushing block 20 withstands in the groove on the slide block 2, and the other end of indent 18 is buckled on the pushing block 20 when depressing.Slide block 2 is provided with limited post 10, limited post 10 horizontal slip in the stopper slot 28 of chute 1; Also be provided with positioning seat 21 and angle modulation screw 25 on the slide block 2, the rotational angle of control rotating shaft 6 is the operating position of cavity and changes blade position.Also be provided with bolt 23 and pressure adjustment screw 24 on the slide block 2, be used for suitably increasing or reducing the pressure of 12 pairs of anilox roll 17 of doctor blade up and down.Spacing collar 22 is two scotch of welding in the rotating shaft 6, presses at two extreme positions and touches positioning seat 21 and angle modulation screw 25, is respectively work and changes the spacing of blade.
As shown in Figure 4, side seal cover 27 is installed, on the side seal cover 27 ink block piece 26 is installed in the two ends of enclosed cavity 15 of the present utility model.Realize compressing of ink block piece 26 and anilox roll 17 roll surfaces by regulating bolt 24.These ink block pieces 26 directly contact with anilox roll 17 roll surfaces, are easy to loss, must often change (when sealed at both ends adjusting is failed).Generally speaking, the slight ink bleed of annular seal space 15 meetings, this is a normal phenomenon, as finding the slight black phenomenon adjustable bolt 23 that drips is arranged, and strengthens the pressure between ink block piece 26 and anilox roll 17 roll surfaces.
The utility model provides a kind of novel inking device, enclosed cavity 15 adopts the aluminium alloy manufacturing, the chamber fluid dynamics Design and the Te Fulong coating of innovation, make the printing ink transmission and clean easilier, can make this device can substitute any old-fashioned rubber roll, single scraper is scraped ink system and multiple roll ink transfer coating method; Pneumatic hydraulic is regulated locking, makes anilox roll and doctor that certain buffering capacity be arranged, and reduces and impacts.Cavity need not to repeat to adjust after installing and accurately adjusting, even change doctor blade, can guarantee that also the doctor blade position is constant, to guarantee uniform best wiping effect; Be with flexible sealing system, guarantee that ink spreader seals fully; Sealing block can directly be fitted on the anilox roll sculptured surface, and does not need the anilox roll two ends smooth; The enclosed cavity loading and unloading need not any aid easily.
