Description

Technical Field

[0001] This utility model relates to the field of gift box processing, and in particular to an anti-wrinkle mechanism for a laminating machine. Background Technology

[0002] Cardboard boxes are the most widely used packaging products in daily life. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. During the production of cardboard boxes, a laminating machine is usually used to attach a thin film to the surface of the cardboard. The film can effectively improve the appearance and waterproof properties of the cardboard box, and increase its practicality.

[0003] When a laminating machine laminates cardboard, large dust particles may be present on the cardboard. This can easily cause air bubbles during lamination, and wrinkles may also form. Furthermore, because the dust particles are small and may adhere very firmly due to static electricity, they are not easily blown away. Therefore, it is necessary to improve this structure to overcome these defects. Utility Model Content
