Abstract
The utility model discloses an offset printing machine spraying type water supply device. The offset printing machine spraying type water supply device comprises a plate cylinder and a form dampening roller connected with the plate cylinder in a rolling mode, the form dampening roller is further respectively connected with a shifting roller and a metering roller in a rolling mode, the metering roller is connected with a water conveying roller in a rolling mode, a closed water supply roller is arranged above the water conveying roller, the water supply roller is connected with a water tank through a pipeline, and small holes are formed in the bottom of the water supply roller. The offset printing machine spraying type water supply device enables alcohol volatilization amount to be reduced in printing production and improves performance stability of wetting liquid due to arrangement of the closed water supply roller. In addition, returned wetting liquid can not contact new wetting liquid in the water supply roller, pollution to the wetting liquid is avoided, and quality of printed products is guaranteed.
Description
Technical field
The utility model relates to a kind of water supply installation, is specifically related to a kind of offset print formula water supply installation that drenches with rain.
Background technology
Offset lithography is the mode of printing of present main flow, mainly finishes according to the immiscible principle of profit, and water supply condition directly influences print quality.The way of supplying water of existing offset print water supply installation is: add electrolyte earlier and be mixed with acid fountain solution in running water, fountain solution and certain density alcohol mixed by a certain percentage being pre-stored in the open tank, then through water bucket roller, metering roll, pass to plate cylinder by version damping roller etc.The weak point of this way of supplying water is: because tank is open, alcohol is volatile, makes the unstable properties of fountain solution; Paper hair in the printing process on the forme, printing ink etc. pass back in the tank along the water route, mix with original fountain solution in the tank, pollute fountain solution, cause print quality to descend or scrap.
Summary of the invention
The purpose of this utility model provides a kind of offset print formula water supply installation that drenches with rain, and has solved existing water supply installation and pollute the problem that fountain solution causes print quality to descend or scrap in printing process.
The technical scheme that the utility model adopts is, a kind of offset print formula water supply installation that drenches with rain, comprise plate cylinder and edition damping roller that leans on that is connected with the plate cylinder roll extrusion, also roll extrusion is connected with metering roll with scurrying damping roller respectively by the version damping roller, metering roll is connected with the roll extrusion of biography damping roller, pass the water supply roller that the damping roller top is provided with sealing, the water supply roller is connected with water tank by pipeline, and water supply roller bottom is provided with aperture.
Characteristics of the present utility model also are,
Pass the damping roller surface and be provided with glue suede.
Pass the damping roller side and be provided with scraper, pass damping roller below be provided with water-supporting disc.
Aperture is no less than 2.
Pipeline is provided with control valve and water pump.
The beneficial effects of the utility model are,
1. the utility model offset print formula water supply installation that drenches with rain, by the water supply roller of sealing is set, the alcohol volatile quantity reduces when making print production, improved the stability of fountain solution, and the fountain solution of passback does not reach fountain solution new in the water supply roller, avoid the pollution of fountain solution, guaranteed the quality of printed matter.
2. the utility model offset print formula water supply installation that drenches with rain by water tank is set, under the situation that does not have printing, can be deposited in remaining fountain solution in the water tank, has reduced the waste of fountain solution.
Description of drawings
Fig. 1 is that the utility model offset print formula water supply installation that drenches with rain passes the water-bound schematic diagram;
Fig. 2 is the utility model offset print formula water supply installation water-supply structure schematic diagram that drenches with rain.
Among the figure, 1. plate cylinder, 2. by a version damping roller, 3. metering roll 4. passes damping roller, 5. water supply roller, 6. scraper, 7. water-supporting disc is 8. scurried damping roller, 9. aperture, 10. glue suede, 11. water tanks, 12. water pumps, 13. control valves, 14. pipelines.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model offset print formula water supply installation that drenches with rain, referring to Fig. 1 and Fig. 2, comprise plate cylinder 1 and edition damping roller 2 that leans on that is connected with plate cylinder 1 roll extrusion, also 3 roll extrusion are connected with metering roll with scurrying damping roller 8 respectively by version damping roller 2, metering roll 3 is connected with 4 roll extrusion of biography damping roller, pass damping roller 4 surfaces and be provided with water imbibition, pass all good glue suede 10 of water-based, pass damping roller 4 sides and be provided with scraper 6, be used for the amount that control passes fountain solution, scraper 6 pressure and angle can be regulated, be provided with water-supporting disc 7 below the biography damping roller 4, when the fountain solution quantity delivered is excessive, scrape off unnecessary fountain solution by scraper 6, collected by water-supporting disc 7 and do the waste liquid processing, pass the water supply roller 5 that damping roller 4 tops are provided with sealing, reduce the volatilization of alcohol, water supply roller 5 is connected with water tank 11 by pipeline 14, and pipeline 14 is provided with control valve 13 and water pump 12, and water supply roller 5 bottoms are provided with aperture 9, aperture 9 is no less than 2, and fountain solution can flow to through aperture 9 and pass on the damping roller 5.
The drench with rain water supply process of formula water supply installation of the utility model offset print is as follows:
Offset print is in printing process, fountain solution in the water tank 11 promotes through water pump 12, enter in the water supply roller 5 through pipeline 14, flow on the glue suede 10 through small holes 9 then with drenching with rain formula, evenly be attached to after wetting through 10 absorption of glue suede and pass on the damping roller 4, successively through metering roll 3 with by a version damping roller 2, axially beat even back supply plate cylinder 1 finally by scurrying damping roller 8 again.
The utility model offset print the drench with rain angle of formula water supply installation by changing scraper 6 and the distance of scraper and 4 of biography damping rollers, thereby the amount of accurately regulating biography damping roller 4 moistened surface liquid are to adapt to urban water demand under the different printing condition.
The utility model offset print formula water supply installation that drenches with rain, by the water supply roller 5 of sealing is set, the alcohol volatile quantity reduces when making print production, improved the stability of fountain solution, and the fountain solution of passback does not reach fountain solution new in the water supply roller 5, avoid the pollution of fountain solution, guaranteed the quality of printed matter.
The utility model offset print formula water supply installation that drenches with rain by water tank 11 is set, under the situation that does not have printing, can be deposited in remaining fountain solution in the water tank 11, has reduced the waste of fountain solution.
