Technotrans central ink supply system consists of the central ink pumping station, pipelines and the printing machine ink fountain three parts. Among them, the central ink pumping station consists of 4 sets of 200kg ink drums and pneumatic ink pumps, which are responsible for pumping ink from the ink tank to the ink conveying pipeline. The power of the pneumatic ink pump is supplied by the central compressed air machine in the factory, and the ink pressure plate pressed against the ink surface prevents air from entering the central ink supply system. The pressure gauge on the pneumatic ink pump control box monitors and regulates the pressure of the entire system. The switch is used to open or close the ink supply work. When the switch is closed, the system stops pumping, and the user can perform adjustment and maintenance work such as replacing the ink tank. The transfer line is a closed high-pressure pipe system with filtration equipment and control valves that can be accurately transported through the network of conveyor lines to the ink fountain of the designated printing unit. An ink supply tube with six evenly distributed, individually controllable nozzles is mounted on the ink fountain of the press to ensure that the ink is evenly distributed and covers the entire width of the ink fountain. The ink level sensor is fixed on the ink supply tube, and the central ink supply system can automatically add ink to the ink fountain to meet the requirements of continuous printing. The Technotrans central ink supply system allows the ink fountain to be fully automatic, semi-automatic and manual with three different ink filling methods. Among them, the fully automatic ink filling method is the most economical and simple way to add ink. When the ink level is lowered, the ink level sensor transmits a signal to the conveying pipe, so that the electric valve is automatically opened, the air pressure in the conveying pipe becomes small, and the central ink pumping station pushes the ink from the ink tank, and the ink automatically flows into the ink fountain through the conveying pipe to Meet the printing machine's demand for ink; when the ink level rises to the set position, the electric valve will automatically close, and the central ink pump station stops sucking ink. In the semi-automatic refilling mode, the ink level needs to be monitored by the operator. When the ink level is lowered, the operator presses the manual key and visually monitors the refilling process. When the ink level rises to a predetermined value, pressing the manual key again stops adding. ink. In the manual refill mode, the operator needs to manually open and close the valve of the delivery pipe. Figure 4 shows the Technotrans central ink supply system control panel, and Figure 5 shows the Technotrans central ink supply system delivery pipe control valve.
