Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping printing, in particular to a separation device used for hot stamping printing. Background Art

[0002] Hot stamping is an advanced printing technology that accurately transfers the aluminum layer in anodized aluminum to the surface of the substrate based on the principle of heat transfer, thus giving it a unique metallic luster and texture. Since the main material is anodized aluminum foil, this process is usually called anodized aluminum hot stamping. In modern printing technology, the processing speed of the hot stamping process can be significantly improved through the precision-designed hot stamping press, thus meeting the needs of large-scale printing and hot stamping work.

[0003] In the hot stamping process, the paper box is used as the substrate. First, the hot stamping plate needs to be accurately installed on the hot stamping machine, and its position and height need to be carefully adjusted to ensure that the hot stamping plate and the anodized aluminum foil are perfectly aligned. Subsequently, the paper box will undergo a hot pressing process during transportation, so that the metal foil (such as gold foil) is firmly attached to the surface of the paper box, forming a bright metal effect.

[0004] However, it is worth noting that during the initial hot stamping stage of the carton, the surface of the carton is usually cooled, which may have a certain impact on the adhesion of the metal foil. The cooled carton surface may reduce the adhesion of the metal foil, resulting in incomplete transfer or uneven hot stamping effect.

[0005] In addition, when hot stamping paper boxes of different thicknesses, it is particularly important to adjust the height of the pressing roller pressed on the surface of the paper box. However, the traditional method of adjusting the height of the pressing roller usually relies on manual operation, which is not only difficult to control accurately, but also inefficient.
