Fig. 1 is the application of the inking device of the present utility model on the set type offset press, its operation principle is: ink fountain rotatablely moves for black reticulate pattern cylinder 3 under dynamic action according to direction as shown, ink fountain picks up printing ink for the ink cell on black reticulate pattern cylinder 3 surfaces in ink fountain, regulate the angle [alpha] of doctor 2
3Make and stop enough printing ink in the ink cell of scraping, printing ink after scraping in the ink cell rolls by giving black reticulate pattern cylinder 3 and 4 pairs of inking blanket cylinders, then inking blanket cylinder 4 rolls with 5 pairs of plate cylinders, realize that the transmission of printing ink from duct cylinder to the forme surface shift, printing ink is coated in the image-text area (the non-graphic zone of forme was coated with fountain solution at last Mo Qianyi) of forme, pass through blanket cylinder 6 again, printing ink is transferred on the paper on impression cylinder 7 surfaces, realized printing.
Fig. 2 has provided the application of the inking device of the present utility model on satellite type offset press.Its motion passes and shown in Figure 1 consistent of black principle, only is that impression cylinder 7 is shared cylinders, so just can the printed web band.
Fig. 3 has provided the application of the inking device on B-B formula offset press of utility model.Its motion and shown in Figure 1 consistent of ink transfer principle only are that impression cylinder 7 is replaced by the blanket cylinder of two units, and the blanket cylinder 6 mutual impression cylinders as the other side of two units just so just can the printed web band.
Fig. 4 has provided the basic structure that ink fountain is given the surperficial ink cell of black reticulate pattern cylinder 3 in the utility model.They are respectively triangular pyramid ink cell a, and truncated rectangular pyramids ink cell b and six terrace with edge ink cell c also can make other ink cell structures, and when using six terrace with edge ink cells, the angle of ink cell and cylinder generatrix direction is 60～70 °.
The utility model has mainly solved following technical problem:
At first solved known offset press inking system device complicated problems: the utility model has adopted isometrical principle, the equal diameters of the diameter of Jimo reticulate pattern cylinder 3 and inking blanket cylinder 4 and the plate cylinder 5 of known offset press, it is corresponding one by one with the surface of plate cylinder to have guaranteed to give the surface of black reticulate pattern cylinder;
Its two homogeneity question that has solved the offset press inking: the main task of known offset press inking system is exactly that printing ink is transmitted the picture and text surface of transferring to plate cylinder equably, the utility model utilizes the principle of ink cell size depth unanimity, makes forme surface picture and text partly obtain China ink amount uniformly.Give black reticulate pattern cylinder 3 owing to used, its surperficial ink cell size depth unanimity has guaranteed the even of quantity of ink on the one hand, can make also that on the other hand the printing ink in the zone that do not have picture and text corresponding with forme continues to be retained in the ink cell by ink cell, is not transferred;
Its three problem that has solved known offset press ink-water balance: the ink-water balance problem is a difficult problem of known offset press, never solution well.Ink cell size depth unanimity of the present utility model, guaranteed to be transported to the printing ink uniformity of forme surface picture and text part, providing the purpose of fountain solution to forme so is exactly that picture and text on the forme and non-graphic zone are distinguished, can use less fountain solution, just can realize the ink-water balance of printing ink.
