Abstract

The embodiment of the invention provides a gold blocking device which comprises a coining device and a preheating device, wherein the coining device is used for coining an electrochemical aluminum foil onto a printing stock; the preheating device is used for preheating the electrochemical aluminum foil and/or the printing stock before entering into the coining device; and the preheating device comprises at least one of heat conduction device, thermal radiation heating device and hot air device. The gold blocking device provided by the embodiment of the invention is capable of increasing the coining speed and reducing the pressure required by coining under the condition of guaranteeing the coining quality, in the manner of preheating the electrochemical aluminum foil and/or the printing stock before entering into the coining device; the pressure difference within a same plate block can be reduced, the pressure endured by the printing stock is more uniform and the mark on the rear side of the printing stock is relieved, so that the coining effect is promoted; the coining pressure is reduced, the demand on the coiling device is reduced and the overall load of the device is reduced, so that the service life of the coining device is prolonged.

Description

technical field [0001] The invention relates to the technical field of bronzing, in particular to a bronzing equipment. Background technique [0002] Hot stamping refers to the process of hot stamping anodized aluminum foil onto the surface of the substrate under a certain temperature and pressure. In order to ensure the smooth transfer of the aluminum layer to the substrate, a heating embossing device is usually used to transfer heat to the anodized aluminum foil. The anodized aluminum foil is heated to melt the hot-melt dyed resin layer and adhesive, and the dyed resin layer is less viscous. After the sensitive adhesive melts, the viscosity increases, and the aluminum layer and the anodized aluminum base film are peeled off and transferred to the substrate at the same time. As the pressure is removed, the adhesive cools and solidifies rapidly, and the aluminum layer adheres to the substrate to complete a hot stamping process. [0003] The heat required for the hot stampin...
