Abstract

The utility model provides a roller feeding device of aggregated intaglio press, comprising an ink groove, a floating base and a roller feeding element, wherein the floating base is fixed on the ink groove, the roller feeding element is mounted on the floating base, the floating base comprises a slide base, a block and a compression spring, the slide base is fixed on the inner sides of two side plates of the ink groove, the block can slide in the slide base, the roller feeding element comprises a roller and a bearing, while the bearing via a baffle ring is fixed on the roller. The utility model can saturate the print point, and eliminate the defects as ink speck, ink line and color aberration or the like.

Description

A kind of set type intaglio press drop roller device

Technical field

The utility model relates to the ink-feeding device of printing machine, more particularly, relates to a kind of set type intaglio press drop roller device.

Background technology

At present, the ink-feeding device of middle low-speed printer adopts open black groove, and forme drum directly immerses in the black groove.But when this kind structure was used on the high speed machine, then printing can produce bad defectives such as the site is unreal, ink speck, the line of ink marker, aberration, makes print quality reduce greatly, can not satisfy user's requirement.

Summary of the invention

The purpose of this utility model is to provide a kind of set type intaglio press drop roller device, and this kind device can make the printing site saturated in printing process, bad defective complete obiterations such as ink speck, the line of ink marker, aberration.

The purpose of this utility model is achieved through the following technical solutions: a kind of set type intaglio press drop roller device, comprise black groove, also comprise float bearing and drop roller assembly, described unsteady bearing is fixed on the black groove, and described drop roller assembly is installed on the bearing that floats.

In such scheme, unsteady bearing comprises slide, slide block and stage clip, and described slide is fixed on the black groove biside plate inboard, and described slide block can slide in slide.

The drop roller assembly comprises drop roller and bearing in this device, and bearing is fixed on the drop roller by back-up ring.

Compared with prior art, the utlity model has following beneficial effect:

1, the drop roller mode arrives printing plate cylinder with the printing ink indirect transfer under the employing, reaches the effect of abundant froth breaking by rolling of drop roller and printing plate cylinder;

2, more help the abundant stirring of printing ink and the circulation rate of quickening printing ink, avoided the line of ink marker and aberration to lack the generation of filling;

3,, guaranteed that printing ink does not throw away yet not spill that printing can not produce ink speck and lack filling because the low black in addition groove of black face height has adopted the special planform of stating.

Description of drawings

Fig. 1 is an ink feeding system structural representation of the prior art;

Fig. 2 is the novel structural representation of drop roller device down of this usefulness;

Fig. 3 is the novel operation principle schematic diagram of drop roller device down of this usefulness.

Among the figure: 1. black groove, 2. slide, 3. slide block, 4. bearing, 5. stage clip, 6. drop roller is 7. gone up the China ink pipe,

8. ink reclaiming pipe, 9. pump, 10. black groove, 11. printing plate cylinders, 12. doctors, 13. printable fabrics, 14. impression rubber rolls, 15. back-up rings.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is done detailed explanation.

Fig. 1 is an ink-feeding device of the prior art, and in figure, printing plate cylinder 11 directly immerses in the black groove 10, and pump 9 injects black groove 10 with printing ink.In printing process, unnecessary printing ink is wiped off by doctor 12.Squeezing action by impression rubber roll 14 and printing plate cylinder 11 is transferred on the printable fabric 13 printing ink.Because printing plate cylinder 11 directly immerses in the black groove 10, cause the China ink amount big, under machine runs up situation, easily produce and get rid of China ink, spatter black situation, cause printing bad defectives such as ink speck, the line of ink marker to occur.

Fig. 2 is the structural representation of this programme.Among the figure, drop roller 6 is installed on the slide block 3 by bearing 4, and slide block 3 can slide up and down in slide 2 inside.Slide 2 is fixed on the black groove 1.Back-up ring 15 is fixed on bearing 4 on the drop roller 6.It is tightr that stage clip 5 makes that drop roller 6 contacts with printing plate cylinder 11, is convenient to printing ink and shifts.

The utility model drop roller device course of work as shown in Figure 3, pump 9 injects black groove 1 with printing ink earlier by last China ink pipe 7, unnecessary printing ink is back in the black groove 10 by ink reclaiming pipe 8, finishes the circulation of printing ink.Drop roller 6 is immersed in the printing ink, has avoided printing plate cylinder 11 directly to contact with printing ink.Drive drop roller 6 by printing plate cylinder 11 rotations and rotate, printing ink is transferred on the printing plate cylinder 11 by drop roller 6, like this by rolling, has only a spot of printing ink to transfer to printing plate cylinder 11, again by doctor 12 further scrapings.Get rid of China ink when having avoided machine to run up like this, effectively, spatter black situation.

Simultaneously, in the process of printing, drop roller 6 plays the effect of Ink stirring stick, can make printing ink more even, the color difference eliminating phenomenon.

The bottom of the black groove 1 in this programme is a circular arc, makes that to deposit the China ink amount few, and the printing ink face is lower, has saved printing ink on the one hand, has guaranteed on the other hand that printing ink does not throw away yet not spill, and printing can not produce ink speck and lack filling.

In addition, splash out the axle center biasing 20mm of the axle center of drop roller 6 and printing plate cylinder 11 for fear of drop roller 6 unnecessary printing ink in operation process.

Claims

1. a set type intaglio press drop roller device comprises black groove, also comprises float bearing and drop roller assembly, and described unsteady bearing is fixed on the black groove, and described drop roller assembly is installed on the bearing that floats.

2. set type intaglio press drop roller device according to claim 1, it is characterized in that: described unsteady bearing comprises slide, slide block and stage clip, and described slide is fixed on the black groove biside plate inboard, and described slide block can slide in slide.
