Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to Figure 3, the development cleaning device of the developing machine of the utility model embodiment comprises developer solution water tank 1, dipper 2, enters roller assembly 4 and 3 the liquid knife system 5 with inlet opening 51 and liquid outlet 52 for transport of printing plates 3, the liquid outlet 52 of liquid knife system 5 is towards the same place on forme 3 surface, developing result is better, and the distance between liquid outlet 52 and forme 3 is between 0.5-3 millimeter; Entering roller assembly 4 is arranged in dipper 2 by rotation axis 6, liquid knife system 5 is arranged on the top of dipper 2 and ensures that liquid outlet 52 aims at the surface of forme 3, liquid knife system 5 is provided with inlet opening 51, and inlet opening 51 is connected with developer solution water tank 1 with the first drawing liquid pump 8 by feed liquor flexible pipe 7.
Pressure-regulating valve 9 is provided with between first drawing liquid pump 8 and liquid knife system 5, can the fluid impulsive force of regulator solution knife system 5; Dipper 2 is connected with developer solution water tank 1 with the second drawing liquid pump 12 by fluid flexible pipe 11, is provided with filtrator 13 between the second drawing liquid pump 12 and developer solution water tank 1, can the automatic recovery developer solution.
Liquid knife system 5 of the present utility model is a kind of triangular structures, distance between the liquid outlet 52 of liquid knife system 5 and forme 3 is between 0.5-3 millimeter, the space of 0.5-3 millimeter is vacated like this in the bottom of liquid knife system 5, the developer solution spraying suitable pressure can be ensured, two of liquid knife system 5 is blocked fixing respectively by two stationary shaft, the top of liquid knife system 5 has three inlet openings 51, developer solution can be pumped into by inserting hollow corrosion-resistant feed liquor flexible pipe 7, the live-roller 10 for transmission forme 3 is also provided with in dipper 2, namely three live-rollers 10 are provided with in forme 3 bottom surface position, forme 3 can be prevented to be out of shape under the impact of hydraulic pressure, increase the gearing of forme 3 simultaneously, dipper 2, developer solution water tank 1 are connected by feed liquor flexible pipe 7 with pressure-regulating valve 9 by the first drawing liquid pump 8, and the developer solution in developer solution water tank 1 pumps by the first drawing liquid pump 8, regulates pressure by pressure-regulating valve 9, send triangle liquid knife system 5 to.When carrying out cleaning, after developer solution flows out from the liquid outlet 52 of liquid knife system 5, enter dipper 2, when the developer solution in dipper 2 reaches certain pressure (such as when developer solution liquid level is apart from forme 310mm place, developer solution liquid level is too high apart from forme 3 surface elevation, be unfavorable for that liquid cutter applies flushing pressure to forme 3), developer solution is flow back in developer solution water tank 1 through the second drawing liquid pump 12, filtrator 13 by fluid flexible pipe 11, completes cyclic process.The process that version is rushed in whole development is passed through to immerse in dipper 2 into roller assembly 4 by forme 3 transmission; three liquid knife systems 5 start to spray the developer solution having pressure simultaneously; after being fallen by the medicine Membrane cleaning of surperficial for forme 3 non-graphic part, then carry out the washing of postorder, oven dry and coating surface protecting glue technique.
