[0029] Among them, the upper liquid level sensor 6 and the lower liquid level sensor 7 can both adopt conventional liquid level sensors in the prior art, and are electrically connected to the external controller according to the prior art. In addition, the solenoid valve is also electrically connected to the external controller. Specifically, when the ink level drops to the lower liquid level sensor 7, the controller controls the solenoid valve to open and add ink to the ink pool 2. When the ink level rises to the position of the upper liquid level sensor 6, the controller controls the solenoid valve to close and stop adding ink. It can intelligently add ink to avoid the ink level being too high or too low.

[0030] The operator can adjust the specific positions of the upper liquid level sensor 6 and the lower liquid level sensor 7 according to actual application requirements. The specific operation is: manually rotate the threaded rod 12 corresponding to the upper liquid level sensor 6 and the lower liquid level sensor 7. The rotating threaded rod 12 drives the lifting seat 10 and the lifting seat 2 11 to move up and down with the upper liquid level sensor 6 and the lower liquid level sensor 7 respectively, so as to realize flexible adjustment of the positions of the upper liquid level sensor 6 and the lower liquid level sensor 7, and facilitate upward removal for inspection, replacement and other operations.

[0034] The working principle of the utility model is as follows: the operator can adjust the specific positions of the upper liquid level sensor 6 and the lower liquid level sensor 7 according to the actual application requirements. The specific operation is: manually rotate the threaded rod 12 corresponding to the upper liquid level sensor 6 and the lower liquid level sensor 7, and the rotating threaded rod 12 drives the lifting seat 10 and the lifting seat 2 11 to move up and down with the upper liquid level sensor 6 and the lower liquid level sensor 7 respectively, so as to realize the flexible adjustment of the position of the upper liquid level sensor 6 and the lower liquid level sensor 7, and at the same time facilitate upward removal for maintenance and replacement and other operations; during the printing process, the ink level is lowered to the lower liquid level sensor When the sensor 7 is detected, the controller controls the solenoid valve to open and add ink to the ink pool 2. When the ink level rises to the position of the upper liquid level sensor 6, the controller controls the solenoid valve to close and stop adding ink. Ink can be added intelligently to avoid the ink level being too high or too low. During printing, the plate roller 5 rotates, and the driving belt 17 and the two driving pulleys 8 cooperate to make the rotating plate roller 5 rotate with the threaded screw 14, and the rotating threaded screw 14 drives the spoiler 13 to reciprocate at the inner bottom end of the ink pool 2 to prevent the ink from settling and make the ink more uniform.
