[0028] The control principle of this utility model:

[0029] During operation, the manual control valve 6 is in the air source closing position, and the solenoid valve 7 is energized. The airflow flows from the air inlet 1 of the solenoid valve 7 to the working port 4, and then passes through the one-way throttle valve A2 to the air inlet 1 of the cylinder, and the cylinder rod retracts, so that the printing roller is in the working position.

[0030] When the machine is shut down, the manual control valve 6 is in the air source closing position, the solenoid valve 7 is in the power-off state, the air flow is from the air inlet 1 of the solenoid valve 7 to the working port 2, through the air inlet 1 of the air control valve 5 to the working port 2, and then through the one-way throttle valve B3 to the air inlet 2 of the cylinder 1, the cylinder rod extends, and the print roller is in the non-working position (disengaged).

[0031] When the machine is shut down, the solenoid valve 7 is in a power-off state, and the manual control valve 6 is in the air source connection position. The manual control valve 6 controls the air control valve 5 to switch the air path.

The cylinder rod retracts and the print roller is in the working position.

[0032] Through the above working principle, the selection switch is in automatic state when the machine is turned on, the printing roller is in the working position, and is in the disengaged position when the machine is stopped.
