Description

One kind auxiliary inking roller

Technical field

The utility model belongs to printing equipment technical field, and the inking roller being related on iron-printing machine, especially one kind aid in Ink roller.

Background technology

For iron-printing machine in printing process, ink system structure, installation and the quality of debugging are directly connected to the final of printing Effect, and most important one of the regulation in ink system transmitting procedure is exactly the regulation to ink roller location, its effect is by through one The ink that serial ink roller is beaten quantitatively is coated between plate cylinder, and according to soft or hard identical arrangement regulation, inking roller belongs to Soft roller, it is driven roll, obtains power by the friction with wavers and plate cylinder and rotate, when inking roller rotates, band Dynamic ink extruding plate cylinder, different layer of ink are formed according to gap length.

The length of usual inking roller circumference is less than plate cylinder circumferential length, after inking, due to the division of ink, original Ink profile still can be retained on ink roller, and is rotated by ink roller, can be transferred to printing iron plate in the form of " ghost " often On.Especially in the case of space of a whole page circumference ink supply great disparity, " ghost " phenomenon is just more prone to occur.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 and Fig. 2 are referred to, a kind of auxiliary inking roller G that the utility model is related to, the auxiliary inking roller are shown in figure G integral installations are on the fixed support J between wallboard, including rubber roll 8, and the axial both ends of the rubber roll 8 are arranged with axial direction The central bore (not shown) of insertion, the first pad 7, are symmetrically equipped with successively from the inside to the outside in the central bore at both ends One roller bearing 6, the second pad 5 and the second roller bearing 4 and spring 3, roll shaft 9, the axial direction of roll shaft 9 are worn in the central bore at both ends Both ends are symmetrically arranged with check ring 2；

The inner of check ring 2 is penetrated to nearly second roller bearing 4 of centre bore, because of its inner face of check ring 2 and Spring 3 is provided between two roller bearings 4, so axial play mutually be present, the outer end of check ring 2 is with being located in roll shaft 9 On roll shaft back-up ring 1 be closely sticked.

Radial equipartition has the connecting hole (not shown) that can be fixedly linked with fixed support J, roll shaft 9 on roll shaft back-up ring 1 Both ends of the surface be fastened on by roll shaft back-up ring 1 on fixed support J.

In the present embodiment, the second roller bearing 4 is single thrust bearing, and the first roller bearing 6 is needle bearing.

Fig. 1 show the ink rubber roll arrangement architecture schematic diagram for including the auxiliary inking roller that the utility model is related to；

Order, inking roller 5 need to be shared according to the rules when installing rubber roll, wherein inking roller VII is on the original basis The increased auxiliary inking roller that the utility model is related to, erection sequence are first to be filled with ink roller II, III, refill inking roller I, IV, VII, in order to ensure that black roll gap pressure reaches requirement, it is necessary to adjust the pressure between inking roller I, II, III, IV and wavers V, VI Pressure between power, and auxiliary inking roller VII and inking roller IV, inking roller is when pressure is adjusted with the eccentric hoop at both ends Angle number position is basically identical to be defined.

Inking roller VII need to carry out overall package between wallboard is loaded, before adjustment position, according to its internal structure, such as Shown in Fig. 2, it is necessary to first engage rubber coated pressure bowl 8 with roll shaft 9.

Load the first pad 7, the first needle roller roller bearing 6, second pad in order respectively first in the endoporus of rubber coated pressure bowl 8 Piece 5, the second unilateral thrust roller bearing 4 and the spring 3 with its end contact, the left and right sides keep symmetrical consistent；Then will Roll shaft 9 is penetrated in the endoporus of rubber coated pressure bowl 8, and check ring 2 is inserted at left and right end, its two inner face is completely attached to spring 3, most Load roll shaft back-up ring 1 in the outermost of check ring 2 of roll shaft 9 afterwards, the inner face of roll shaft back-up ring 1 need to be in close contact check ring 2 End face outside, ensure that check ring 2 will not be because axially having a gap and single left and right vibration.

Finally, between the auxiliary ink roller G installed being installed on into wallboard by fixed mount J, and adjust what it was combined The gap of other ink rollers and the depth of parallelism.

Its operation principle of the inking roller that the utility model is related to approximately as：

Ink feeding system in equipment has either all had influence on final printing quality in design, manufacture, installation and debugging, As shown in Figure 1, it is important to which whether the ink being embodied on inking roller I, II, III, IV can fill and uniformly, by institute in equipment The girth of four inking rollers of configuration is definite value, and plate cylinder Y girth changes according to the repetition girth of product, is individual indefinite Value, plate cylinder Y rotates a circle, by the printing ink transfer on inking roller I, II, III, IV to plate cylinder Y, if this four Ink on inking roller can be supplemented uniformly in time, then, the ink being transferred on plate cylinder Y is just very sufficient, would not Occur " ghost ", if the ink on several inking rollers all uniformly, cannot be supplemented sufficiently, then, it is transferred to plate cylinder Y On ink may be variant, the few place of ink, color saturation will produce ghost with regard to weak, so, on the original basis One group of auxiliary inking roller VII that can make ink roller axial motion of addition in addition, it is therefore an objective to upset the ink trace on original inking roller IV Mark, the ink thickness on ink roller IV is adjusted, makes its uniform.So as to efficiently control the generation of " ghost " phenomenon.

The auxiliary inking roller VII that the utility model is related to is that the both ends of a set of roll shaft are fixed on the fixed support between wallboard Rubber coated pressure bowl on J, as shown in Fig. 2 the two side ends endoporus of rubber roll 8 is equipped with pad 5,7, also roller bearing 4,6 and spring 3, roller Axle 9 therefrom penetrates, and the two of roll shaft 9 is inserted in check ring 2 and entered in the both ends endoporus of rubber roll 8, loads spring in its both sides endoporus of rubber roll 8 3 purpose is rubber roll 8 is made axial motion along roll shaft 9, and the interior step surface of check ring 2 is played by top pressure spring 3 to consolidate Determine relative position of the rubber roll 8 in axial direction, the both ends of the surface roller rest shaft retaining ring 1 of roll shaft 9 is installed in the fixed branch between wallboard securely On frame J, it is set to ensure the position with auxiliary inking roller G.

Above example is only for illustration of the utility model, rather than to limitation of the present utility model, relevant technical field Technical staff, in the case where not departing from spirit and scope of the present utility model, various conversion or modification can also be made, because This all equivalent technical scheme should also belong to category of the present utility model, should be limited by each claim.
