[0002] In the printing process of bill rotary printing press, the use of fountain solution is an indispensable link, which plays a vital role in ensuring printing quality and extending machine life. However, the traditional way of treating fountain solution is often one-time and directly discharged after use, which not only causes waste of resources but also brings environmental pollution. In order to solve this problem, the fountain solution device of bill rotary printing press that can recycle fountain solution came into being;

When the system is working, the high-pressure water pump draws out the cooling water with good proportion in the water tank, pressurizes it and stabilizes it through the pressure regulating device, and sends it to the water spray rod. The computer precisely controls the opening and closing of multiple solenoid valves through the control card, so that the solenoid valves in different areas correspond to their respective areas, and the nozzle is used to control the spray angle and fan-shaped area to achieve accurate coverage of water at different layout positions. During the printing process, the computer and wireless data transmission technology are used to accurately control the opening and closing of each solenoid valve to obtain the required amount of dampening water.

[0004] When the above-mentioned prior art is in use, a plurality of nozzles are arranged on a water spray rod to spray water on the printing plate of the rotary printing press. However, there are still gaps between the plurality of nozzles, which results in that some positions of the printing plate of the printing press cannot be well soaked, and the plate is not fully moistened. In addition, some liquid will fall during the spraying process, which is inconvenient to collect and recycle, resulting in a waste of resources. Therefore, further improvements can be made.
