AI Technical Summary
Existing PVC embossing equipment suffers from low natural cooling efficiency, causing the decorative film to easily stick to the embossing shaft. Furthermore, the cooling distance cannot be adjusted according to the thickness of the decorative film, affecting the embossing process.
A roller embossing device for 3D hot pressing decorative film was designed, which includes an adjusting pressure roller and a positioning pressure roller, and is equipped with a cooling structure and an adjusting cooling structure. Rapid cooling is achieved through a ventilation frame and a ventilation pipe, and stable demolding of the decorative film is ensured through a linkage structure and a gravity ring groove.
It achieves rapid cooling and stable demolding of the decorative film, prevents the embossing from wearing and adhering in a hot and soft state, and improves the efficiency of the embossing process.
