Description

Technical Field

[0001] The utility model relates to the technical field of packaging film printing equipment, in particular to a packaging film double-sided printing and winding device. Background Art

[0002] In the prior art, in order to achieve double-sided printing of the packaging film, it is usually necessary to print on both sides of the packaging film after it is led out from the unwinding roller, that is, the packaging film needs to be guided by the guide roller group first, enter between the first group of printing rollers and the embossing roller, and be printed on one side. After passing through a drying box to completely dry the ink, the packaging film is guided to between the second group of printing rollers and the embossing roller to print on the other side, and then pass through a drying box to completely dry the ink before being guided to the winding roller for collection.

Otherwise, the printed ink is easily stained on the surface of the guide roller, affecting the printing effect. Therefore, the process of winding the packaging film after double-sided printing needs to go through two independent processes of printing, drying, and printing and drying, which increases the printing time and is not efficient.
