Ultrasonic automatic ink-adding system
Elpo. fill automatic ink-adding system consists of ink pump, printing ink pipeline, ink-adding control box, self-reset pneumatic control valve, ultrasonic liquid level sensor and ink-adding lever. A continuous 25bar pressure will be formed in the pipeline when the printing ink passes through the pumping pipeline of ink pump. When the ultrasonic liquid level sensor detects that the liquid level is lower than the set value, the system will open the pneumatic control valve to make the printing ink pass through the ink-adding lever and inject into the printer duct. When the liquid level reaches the set value, the system will close the pneumatic control valve, and the adding of printing ink will be stopped. Pepperl + Fuchs ultrasonic sensor is used for the system, which has flexible reaction and reliable performance. The button box has two modes: manual ink-adding and automatic ink-adding. It needs to be set as automatic ink-adding mode when the printer starts the production, and the manual ink-adding mode can be set in another time.
The advantages of this system are: The quantity of printing ink in the duct can be controlled accurately. The system can automatically add the printing ink in case of lacking, which reduces the trouble of manual ink-adding. The quantitative ink supply can be realized and the waste of printing ink can be reduced by setting the level of printing ink.
