Abstract
The utility model relates to the driving device of a printing press water roller, which is especially suitable for the driving device of a press water roller of a flat plate offset press. The utility model is composed of a motor, gears, a shaft coupling, a press water roller, a bearing, etc. The utility model is characterized in that the press water roller directly drives a pair of speed reducing gears 5 and 6, a roller 7 and a shaft 9 with a pulling hole to rotate by the motor 1 through the shaft coupling 2. The utility model has the advantage of the adjustable rotary speed of the press water roller. Besides, the rotary speed of the press water roller can be changed according to the quality requirement of printing articles in the process of printing. The utility model can provide proper water quantity.
Description
The utility model relates to the drive unit of a kind of printing machine by the version damping roller, is particularly useful for edition damping roller drive unit that leans on of offset print.
The cardinal principle of offset print printing is to utilize printing to go up picture and text ink affinity is partly arranged, non-graphic partly has hydrophily, provide water and China ink to forme respectively, make its non-graphic partly go up water and picture and text are partly gone up the transfer printing of China ink back on rubber cylinder, utilize pressure again transfer printing on paper, thereby on paper, obtain required printing.As can be seen: concerning offset print,, come to provide the essential water yield and China ink amount to printing but all have moistening even ink system no matter its version is difference how.
Traditional wetting system as shown in Figures 1 and 2.Though the wetting system pattern between them is different, all be from bucket, to take water out of by going out damping roller, after metering roll is regulated water film thickness, finally pass to by the version damping roller to provide the water yield to forme.This shows that they all have one by the version damping roller, by to rolling water being transported on the forme, therefore must rotate by the version damping roller with plate cylinder by the version damping roller.
Present domestic and international various offset presses, its drive unit by the version damping roller mainly contains two kinds, first kind is representative with Fig. 1, have the wetting system of scurrying the damping roller formula, it itself does not drive power by version damping roller 10, its rotation be its with plate cylinder 11 with scurry damping roller 15 and contact the back and have under the certain pressure situation, rely on frictional force to drive its rotation by version damping roller and the formation of the plate cylinder space of a whole page.This transmission is directly relevant with the pressure size, and the excessive roller distortion of pressure is serious, the too small roller that can not guarantee again of pressure can uniform rotation.Especially after long-term the use, roller surfaces is aging, the cylindrical hardening, becomes light, and frictional force is reduced, and causes phenomenons such as the irregular generation of roller rotating speed throws switch, skids, and in case by after the version, under the effect of pressure with plate cylinder to rolling, its roller speed can not be controlled.When the plate cylinder rotating speed is high, also just high by version damping roller rotating speed, vice versa.Another disadvantage of this version is exactly the rotating speed that can not change according to the situation of printing by the version damping roller, so that the suitable water yield to be provided.
Second kind is the conventional wetting system of representative with Fig. 2, its power that leans on version damping roller 10 is from plate cylinder 11, its principle is seen Fig. 3 and Fig. 4, and it is to rotate by come driven gear 18 to make by version damping roller 10 by the gear on the plate cylinder 11 17, and mainly there are two shortcomings in this structure:
In case after 1 gear 17,18 installed, its speed ratio can not change, it changes with the height of plate cylinder rotating speed, and what have first kind of mode too can not regulate the rotating speed that leans on the version damping roller with printing, so that the suitable water yield to be provided.
2, in case diminish by 10 abrasions of version damping roller, diameter, pressure by version damping roller and forme will reduce, even throw off, can't pass water, at this moment need to increase pressure and just must reduce centre-to-centre spacing A1, but because the centre-to-centre spacing A1 of gear is unalterable, will produce the gear dieback does not so change, and the situation that pressure is not also adjusted.Only take to change the bigger new roller of diameter and solve this moment.
The purpose of this utility model is exactly to be to provide a kind of rotating speed by the version damping roller to require situation to become according to print quality, supplies water rationally the drive unit by the version damping roller that the life-span is high.
The purpose of this utility model is achieved in that the driving or installing by the version damping roller of a kind of printing machine, edition damping roller drive unit that leans on that is particularly useful for offset print, by motor, gear, shaft coupling, form, it is characterized in that directly driving the axle 9 that a pair of reduction gearing 5,6, roller 7 and band dial mouthful by motor 1 through shaft coupling 2 by version damping roller 10 drives by version damping roller and bearing etc.
The purpose of this utility model can also further be realized by following technical measures.
Aforesaid drive unit, motor 1 be can stepless adjustment direct current or AC servo motor, and motor 1 is fixed on the wallboard 20.
Aforesaid drive unit, gear 5 is a gear shaft, is bearing in the cover 3 that is loaded on the wallboard 21 through two bearings 4.
Aforesaid drive unit, the geared sleeve that gear 6 is dialled mouthful for band is bearing on the wallboard 22 through pair of bearings 8, gear 6 on the one hand and gear 5 engagements, on the one hand through dialling mouthful, power being passed to the axle 9 that band is dialled mouthful by roller 7.
Aforesaid drive unit, 9 one end of band group mouth are dialled mouth, roller 7 driven rotary by gear 6 warps, and the other end passes to power warp group mouth, roller 7 by an edition damping roller 10.
Aforesaid drive unit is regulated by the pressure of 11 of version damping roller 10 and plate cylinders, changes centre-to-centre spacing A by 11 of edition damping roller 10 and plate cylinders around the swing of gear 5 centers by gear 6
3Reach.
This practical advantage is: owing to directly driven through a pair of reduction gearing by motor by the version damping roller, therefore, the rotating speed of damping roller can require situation to become according to print quality, supply water rationally, and roller life-span height.
