Description

Technical Field

[0001] The utility model relates to a pressing device, in particular to a pressing device used for composite paper production, belonging to the technical field of composite paper production. Background Art

[0002] Composite paper is a versatile paper material, made by combining paper with other materials (such as plastic film and aluminum foil) through a specialized process. This paper combines the advantages of different materials, such as paper's printability and biodegradability, with the waterproof, moisture-proof, and abrasion-resistant properties of plastic film, allowing for a wider range of applications. Composite paper typically has a plastic film on the surface, which imparts excellent flexibility and printability.

[0003] Lamination of composite paper involves combining paper with other materials (such as plastic film or aluminum foil) using a laminating device. The laminating device uses heat or pressure to tightly bond the different materials, creating composite paper with diverse properties. However, existing laminating devices require operators to manually adjust pressure and temperature, resulting in low efficiency and difficulty ensuring consistent and accurate lamination. Pressure and temperature fluctuations during the laminating process can affect product quality. Furthermore, existing laminating devices cannot detect product defects promptly, resulting in a low yield. Therefore, a laminating device for composite paper production is proposed.
