Furthermore, the oven is also communicated with a second pipeline, and the second pipeline is communicated with the ink box.
A part of hot air after heating in the oven can be diffused into the second pipeline, and the second pipeline transfers the hot air into the ink box to heat the ink box, so that the condition of preventing the ink from being condensed can be achieved.
Further, a one-way valve for preventing ink in the ink tank from escaping is arranged on the second pipeline.
The one-way valve is provided in the second conduit to prevent ink from escaping with the air as the piston plate moves downwardly, which draws air from the ink tank as the piston plate moves downwardly.
Further, printing mechanism still includes the ink roller of going out that is equipped with in the china ink case, goes out the china ink roller below and is equipped with the printing roller, the printing roller with go out the contact of china ink roller.
And the ink outlet roller transfers the ink in the ink box to the printing roller, and the printing roller completes the printing of the aluminum foil.
Further, a spring is connected between the piston plate and the rubber plate.
The spring between the piston plate and the rubber plate is arranged, and the rubber plate can slide up and down more easily under the driving of the spring.
Further, the stirring unit is a stirring fan blade.
Set up stirring fan blade and stir printing ink, when second wedge pole drove stirring fan blade and reciprocated, printing ink can form the swirl in the china ink case, and stirring fan blade receives the influence of swirl, and self just can rotate, also can stir printing ink.
