Description

Technical Field

[0001] The utility model belongs to the technical field of packaging box processing, and particularly relates to a film laminating device for packaging box processing. Background Art

[0002] In the process of packaging box processing, it is necessary to perform film laminating on the printed matter that makes up the packaging box. By covering a transparent film on the surface of the printed matter, its durability, aesthetics, and protection can be improved. Film laminating can enhance the gloss, waterproofness, abrasion resistance, and ultraviolet resistance of the printed matter, making the packaging box processed therefrom more suitable for various application scenarios.

[0003] In the existing film laminating device for packaging box processing, a conveying module composed of conveying rollers and a motor is used to convey the printing paper to be film laminated. During the conveying process, the cooperation of guide rollers, a film laminating module, and a film laminating roller is used to cover the film to be laminated on the printing paper on the printed matter. Therefore, the surface film laminating of the printed matter is completed during the packaging box processing. Due to the characteristics of the plastic film itself, the transparent film to be covered has a certain elasticity, making it have a certain tension. The surface of the plastic film will form wrinkles and corrugations under the continuous change of the guide rollers due to the tension. The existence of these wrinkles and corrugations may affect the film laminating effect on the printed matter during hot press film laminating. Therefore, a tension adjusting frame driven by a spring is used to adjust the tension of the film during the printing process. However, in the actual use process, the resilience of the spring will decrease after using for a certain period of time, which may affect the tension adjusting effect and reduce the printing effect.
