Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
This full-automatic central fountain solution system joins supplied with constant voltage system, comprise the pure water cylinder 1 for splendid attire pure water, for the fountain solution bucket 2 of splendid attire fountain solution, for alcohol bucket 3 and the mixed liquor bucket 4 of splendid attire alcohol, pure water cylinder 1 is connected to the import of proportioning pump I 9 through water inlet pipe 6 by water pump 5, alcohol bucket 3 is connected to the import of proportioning pump I 9 by feed tube I 7, water inlet pipe 6 is provided with magnetic valve 8, the outlet of proportioning pump I 9 is connected to mixed liquor bucket 4 through drain pipe 14, fountain solution bucket 2 is connected to the import of proportioning pump II 10 by feed tube II 12, the outlet of proportioning pump II 10 is connected to mixed liquor bucket 4 through drain pipe 14, the lower end of mixed liquor bucket 4 is connected to printing machine dampening system by liquid pump 16 through woven hose 15.During work, magnetic valve 8 is opened, and water pump 5 starts extraction in pure water cylinder 1, and proportioning pump I 9 starts by the alcohol in feed tube I 7 extraction alcohol bucket 3 and directly pumps in mixed liquor bucket 4 through drain pipe 14 after being mixed with pure water by alcohol according to the ratio of regulation.Fountain solution is also proportionally pumped in mixed liquor bucket 4 from fountain solution bucket 2 by feed tube II 12 by proportioning pump II 10 simultaneously, realizes automatically in mixed liquor bucket 4, allocating fountain solution.Deployed printing standard fountain solution through liquid pump 16 automatic transport in the dampening system on printing machine.Overcome the drawback that artificial interpolation causes fountain solution stoste instability, substantially increase printing quality.
Can also comprise PH value detector 21, the measuring probe of PH value detector 21 is installed in mixed liquor bucket 4.The pH value of fountain solution is that forme blank parts generates hydrophilic inorganic salt, and keeps clean necessary condition, and very large on the transfer effect impact of ink, fountain solution pH value meta-acid or meta-alkali are all unfavorable for normally carrying out of offset printing.So, in order to give full play to the effect of fountain solution in offset printing, needing the strict pH value controlling fountain solution, having controlled fountain solution pH value well, also just controlled plate quality, rate of drying, interfacial tension well.First is that pH value can not be too high, because acid weak, hydrophilic glue-line not easily generates, and fountain solution surface tension can sharply decline, and ink water content can uprise, thus causes the problem such as ink emulsification and serious dot gain; Meanwhile, the ability that fountain solution cleans forme also can decline.Second is that pH value can not be too low, otherwise affects the oxidation drying speed of ink self, and the infringement of aggravation to forme, corrosion blank parts Grains and areas photosensitive material, make printing plate resistance force decline, and may destroy alkaline paper face coat.Facts have proved, concerning PS version, the fountain solution pH value scope meeting printing technology requirement is most 4.8 ~ 5.5.Therefore when preparing fountain solution, very large on impacts such as the damping effect of fountain solution and ageing resistances by the soft durometer of water.The pH value of mixed liquor in mixed liquor bucket 4 can be measured by PH value detector 21 in real time, further increase printing quality.
Can also comprise electric conductivity detector 22, the measuring probe of electric conductivity detector 22 is installed in mixed liquor bucket 4.Electrical conductivity of water affects the origin cause of formation to printed matter: fountain solution dynamic surface tension depends on the concentration of wherein damping stoste, and concentration is higher, and surface tension is lower.Some commercial automatic conveying devices can control the concentration of damping stoste, in the hope of reaching a predetermined electrical conductivity.When entering electrical conductivity of water and being excessive, will cause the change of damping original liquid concentration, its result is exactly oil-water ratio imbalance, causes offset printing fault.If the ratio of damping stoste is quantitative and accurately control as other unit, problem may be little, but when the electrical conductivity of water of supply changes very large, effect mutual between profit still can be caused unbalance.Generally speaking when electrical conductivity of water has fluctuation, can impact the Automated condtrol of printing house's fountain solution in printing process and detection, run into this situation, the measure that take must carry out strict monitoring to the quality of water, controls well into electrical conductivity during water.Therefore can be measured the conductivity value of mixed liquor in mixed liquor bucket 4 by electric conductivity detector 22 in real time, further increase printing quality.
Can also comprise and be installed on liquid level gauge I 11 in pure water cylinder 1 and mixed liquor bucket 4 and liquid level gauge II 13 respectively.When the liquid level gauge liquid level gauge II 13 measurement liquid level in mixed liquor bucket 4 is too low, control system can control that water pump 5 works, Controlling solenoid valve 8 is opened and control ratio pump I 9 and proportioning pump II 10 work, and is automatically filled in mixed liquor bucket 4 by the fountain solution of mixing.When the liquid level that the liquid level gauge I 11 in pure water cylinder 1 is measured in pure water cylinder 1 is too low, control system fills into pure water, further increases this full-automatic central fountain solution system and joins supplied with constant voltage system automation level.
Water inlet pipe 6 and woven hose 15 can be separately installed with stop valve II 20 and stop valve I 17.In time overhauling, staff can manual-lock stop valve II 20 and stop valve I 17, further increases convenience.
Further also comprise and be installed on check valve 18 on woven hose 15 and Pressure gauge 19.Check valve 18 makes the mixed fountain solution of mixed liquor bucket flow in printing machine dampening system through woven hose 15, prevents reverse flow, improves the reliability used.Conveniently can know output pressure by Pressure gauge 19, be convenient to adjustment.
