[0002] Packaging bags often need to be printed in the modern production process, especially in the food, pharmaceutical and cosmetic industries. Printing is not only used to identify product information, but also to enhance the appearance of the packaging. After printing, packaging bags usually need to be dried to ensure that the printed pattern is dry and solidified to avoid blurring or peeling of the pattern.

[0003] Under the current technical background, improving the drying efficiency and uniformity of printed patterns on packaging bags is a key demand in the industry. Existing drying equipment usually uses a simple hot air drying method. During the drying process, the packaging bags lack auxiliary positioning structures, which makes it difficult for the packaging bags to maintain a stable position after being sprayed, and the printed patterns are easily uneven due to movement or deformation, which affects the printing quality; at the same time, traditional drying equipment is difficult to effectively concentrate hot air on the printed pattern, and the heat conduction is easy to cause low drying efficiency, high equipment energy consumption, and poor drying uniformity. These problems need to be improved. Utility Model Content
