Description

Technical Field

[0001] The present invention belongs to the field of hot stamping equipment, and specifically relates to an aqueous hot stamping machine and an aqueous glue. Background Art

[0002] Hot stamping refers to the process of hot stamping an electroaluminum foil onto the surface of a substrate under certain temperature and pressure. The hot stamping process utilizes the principle of hot press transfer to transfer the aluminum layer in the electroaluminum onto the surface of the substrate to form a special metallic effect. Since the main material used in hot stamping is the electroaluminum foil, hot stamping is also called electroaluminum hot stamping. During the hot stamping process, an aqueous glue needs to be coated on the sizing roller with a pattern on its surface so that the aqueous glue is evenly coated on the outer peripheral wall of the sizing roller. However, during the hot stamping process, the sizing roller rotates. If the aqueous glue is scraped onto the rotating sizing roller by a scraper;

[0003] But when it is necessary to stop the machine, the sizing roller stops rotating, resulting in the stop of the flow of the aqueous glue. In the case of a short-term shutdown, it will not affect the properties of the glue. In the case of a long-term shutdown, the aqueous glue will solidify due to the stop of the flow, causing waste of the aqueous glue. And when the transfer is completed, when there is a large amount of excess aqueous glue, the glue needs to be recycled and stored again. The traditional recycling method is to collect it manually with a scraper, which takes a long time and will also cause the solidification of the glue. Summary of the Invention
