Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping machines, in particular to a local hot stamping machine for cosmetic bottles. Background Art

[0002] Hot stamping mainly utilizes the principle of heat pressure transfer. Under a certain temperature and pressure, the hot stamping film is brought into contact with the hot stamping plate and substrate. As the heating of the electric heating plate causes the hot stamping plate to have a certain amount of heat, the hot stamping film is heated to melt the hot-melt dyed resin layer and adhesive, the adhesion of the dyed resin layer decreases, while the viscosity of the special heat-sensitive adhesive increases after melting. The pattern on the hot stamping film is transferred to the substrate. As the pressure is removed, the adhesive quickly cools and solidifies, and the pattern is firmly attached to the substrate to complete the hot stamping process. The hot stamping machine is the equipment that completes the hot stamping process.

[0003] In order to improve the appearance of cosmetic bottles, corresponding patterns are stamped on the cosmetic bottles by hot stamping machines. Since the current hot stamping machines adopt an open structure, during the hot stamping process, the hot stamping plate and the hot stamping film are exposed, and the temperature of the hot stamping plate is easily lost, making the hot stamping temperature unstable. Bubbles are easily generated after hot stamping, which affects the hot stamping quality of the cosmetic bottles. Utility Model Content
