Abstract

The utility model relates to an improvement of a roller printing plate in a gravure printing. The utility model is composed of an outer body, an inner bladder, sealing sleeves, etc. The outer body and the inner bladder are made of two different metal materials. The rolled plates are welded into cylinder shapes and are pressed and rolled inside. The out-of-roundness and non-straightness of a roller can be ensured. Both ends of the roller are provided with the sealing sleeves. Compared with a cast copper roller, the utility model has light weight, good quality, clear manufacture layout, and low cost. The utility model is well popular with the printing industry.

Description

Gravure winding up roller forme body

The utility model relates to parts in the printing equipment, is the improvement of the roller forme in the intaglio printing specifically.

Along with the development of printing industry, the demand to printing roller in intaglio printing also correspondingly increases.The ormolu (ZH62) that the exhausted major part of the blank of material of existing printing roller is casting processing, it is to process by the melting casting, so exist print roller wall thickness, Heavy Weight, particularly surface roughness and density contrast, the space of a whole page is clear inadequately and influence printing quality, and some is because density contrast, though through fine finishining, but blemish still exists, and causes the roller stock surface to make a plate.

It is a kind of in light weight that the utility model provides, the intensity height, and cost is low, and is widely applicable, the gravure winding up roller forme body that superficial density is high.

The utility model is to realize like this, gravure winding up roller forme body is to be combined by ectosome, inner bag, endoporus, vexed cover, ectosome is two kinds of different metal materials with inner bag, volume metal plate welding back becomes tubular, through interior roll extrusion, guarantee that the out-of-roundness of roller and nonstraightness are combined closely both, vexed cover is installed in the endoporus two ends, vexed cover and end face junction of the edges of two sheets of paper welding after endoporus combines are combined closely the three more.Less when the roller footpath, length with one or some detachable support rings support roller inwalls, substitutes inner bag more in short-term, has conical bore to communicate with endoporus in the vexed cover in two ends.

Be described further below in conjunction with drawings and Examples:

Embodiment 1:

See shown in Figure 1ly, intaglio plate winding up roller forme body is by ectosome 1, inner bag 2, endoporus 3,4 compositions of vexed cover.Ectosome, be to adopt the higher brass copper coin (H62) of superficial density, inner bag is selected the A3 cold-reduced sheet for use, with ectosome brass sheet and inner bag cold rolled strip coil metal plate, the welding back becomes tubular, adopts special interior rolling technology again, makes ectosome and inner bag closely be squeezed into one, not only guaranteed the out-of-roundness and the nonstraightness of roller, the higher copper coin of original density is improved once more.By adorning vexed cover 4, there are conical bore 5 and endoporus 3 to communicate in the vexed cover 4 in the two ends of winding up roller forme body endoporus 3, vexed cover 4 and end face junction of the edges of two sheets of paper welding after endoporus combines, pad 6 is combined closely the three more, sees shown in Figure 2.After fine finishining and plate-making, this winding up roller forme detects on space of a whole page proof press, and the specimen page space of a whole page is very clear, and superficial density is far above casting copper roller.This roll body adapts to big roller and directly prints.

Embodiment 2:

See shown in Figure 3, intaglio plate winding up roller forme body is by ectosome 1, inner bag 2 is substituted by support ring 7, endoporus 3,4 compositions of the vexed cover in two ends, ectosome are to adopt the higher brass copper coin (H62) of superficial density, the volume metal plate is welded into tubular, adopt special interior rolling technology again, guarantee the out-of-roundness and the nonstraightness of roller, the higher copper coin of original density is improved once more.Inner bag is selected spheroidal graphite cast-iron for use is the support ring 7 of material, and support ring is made detachable, sees Fig. 4, regulates with taper bolt.After winding up roller forme body becomes tubular, support ring 7 is installed in the winding up roller inwall does the rigidity support, according to the needs of winding up roller diameter and length, can guarantee intensity and service property (quality) by adorning one or some support rings, the vexed cover 4 of packing at the two ends of endoporus 3 again, in have conical bore 5 and endoporus 3 to communicate, see Fig. 3.Vexed cover 4 and end face junction of the edges of two sheets of paper welding after endoporus 3 combines.

This intaglio plate winding up roller forme body, owing to adopt unique manufacturing process to compare with casting copper roller, in light weight, quality is good, the superficial density height, the space of a whole page of making is clear, has saved cost and raw material again, adapt to the roll body of doing all size,, be subjected to the welcome of printing industry deeply through market survey.
