[0003] In the process of printing aluminum foil for pharmaceutical packaging, since it is difficult to achieve a completely dust-free production environment, the surface of the aluminum foil easily absorbs dust, which not only affects the printing quality, resulting in poor ink transfer, blurred printing, ink shortage and other problems, but also may cause dust particles to be mixed between the ink and the aluminum foil, reducing the ink adhesion, thereby affecting the quality of printing on the pharmaceutical aluminum foil packaging.

[0004] Combining the above two issues, we will find that it is difficult to avoid the above problems at the same time when the existing devices on the market are in use, and even if they can be solved, they need to be connected to external devices, which makes it impossible to achieve the desired effect. Therefore, we propose a pharmaceutical packaging aluminum foil printing device and a method of using the device, which can remove dust from the aluminum foil during use to prevent the aluminum foil from absorbing dust and affecting the ink transfer quality.
