Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a circulating water supply device for a bill rotary printing machine provided with a filtering mechanism. Background Technique

[0002] A rotary printing machine is a traditional printing device. The rotary wet offset printing technology requires dampening solution to clean the printing plate surface, ensuring the cleanliness of the printing plate to improve the reducibility of the printing surface and making the colors more vivid. During the printing process of existing printing machines, the paper needs to be kept moist. Therefore, a water tank is arranged below the printing roller. In this way, through the rotation of the printing roller, the water in the water tank is transferred to the paper through the printing roller, thus ensuring the moisture of the paper. Therefore, during the actual operation process, workers need to add water to the water tank regularly to ensure the normal progress of printing.

[0003] Chinese Patent Authorization Publication No. CN208855229U discloses a circulating water supply device for a printing machine, including a printing machine body and a water tank located inside the printing machine body. A water tank is arranged outside the printing machine body. An inlet pipe and an outlet pipe are respectively arranged on the water tank. A water pump is arranged on the inlet pipe. The front end of the inlet pipe passes through the water tank and is located inside the water tank. A water level pipe is arranged inside the water tank. The water level pipe is connected to the outlet pipe. Under the action of the water pump, the water in the water tank is continuously pumped into the water tank. When the water level in the water tank is higher than the top of the water level pipe, the water higher than the water level pipe will flow back into the water tank through the outlet pipe, thus ensuring the constancy of the water level in the water tank. Moreover, it does not require workers to add water to the water tank regularly, improving the printing quality. At the same time, the height of the water level in the water tank can be controlled by adjusting the height of the water level pipe to meet the needs of different printings.

[0004] The above-mentioned existing technical solutions have the following deficiencies: This circulating water supply device is composed of the upper pipe and the lower pipe sleeved together. By adjusting the position of the upper pipe, the height of the water level in the water tank is changed. It is necessary for the staff to adjust the water level pipe inside the water tank, which is rather troublesome and easily brings bacterial impurities on the hands into the solution inside the water tank, affecting the printing effect. No improvement has been made, and it is necessary to design a circulating water supply device for a bill rotary printing machine provided with a filtering mechanism to solve the above problems.
