Description
Technical Field
The invention relates to the field of surface decoration processes, in particular to a gold stamping device and pad printing gold stamping equipment.
Background
The gold stamping process is to transfer an aluminum layer in the electrochemical aluminum to the surface of a printing stock by utilizing the principle of hot-pressing transfer to form a special metal effect, and because the main material used for gold stamping is the electrochemical aluminum foil (gold stamping foil), the gold stamping is also called the electrochemical aluminum hot stamping. Electrochemical aluminum foils are typically constructed of multiple layers of material, often P E as the substrate, followed by a release coat, a color coat, a metal coat (aluminized), and a glue coat.
The basic gold stamping process is that under a pressure state, namely a state that the alumite is pressed by a hot stamping plate and a printing stock, the alumite is heated to melt a hot-melt organic silicon resin layer and an adhesive on the alumite, the viscosity of the organic silicon resin melted by heating is reduced, and the viscosity of the special heat-sensitive adhesive is increased after being melted by heating, so that the aluminum layer and the alumite film are peeled off and simultaneously transferred to the printing stock. With the removal of the pressure, the adhesive is rapidly cooled and solidified, and the aluminum layer is firmly attached to the printing stock, thereby completing a hot stamping process. The gold stamping is divided into hot stamping and cold stamping. Hot gold stamping is to place gold stamping foil between a mould and a workpiece, the mould is to carve patterns on an aluminum plate or a hard silica gel plate by machine carving or chemical etching, the mould is heated to 120-150 ℃, then metal foil is pressed on the surface of the workpiece for several seconds, then the gold stamping foil which is not hot stamped is separated from the workpiece, and the gold stamping is finished. Because the pattern is etched onto the mold, the metal foil pattern is hot-stamped onto the workpiece surface. Like hot stamping, cold stamping or cold foil transfer presses the metal foil to the surface of the workpiece. The hot stamping foil is only provided with no glue on the bottom layer and does not need an aluminum die for cold stamping, and is most commonly used in the clothing industry, large cold stamping patterns are arranged on clothes or cold stamping patterns are arranged on packaging films, the cold stamping is to print the glue patterns on the clothes or workpieces by silk screen printing, and then metal foils are stamped on the patterns. Example cold stamping a large pattern on T-Shirt: and (3) cold ironing firstly prints a glue pattern on the T-Shirt by using a screen printing method, placing the T-Shirt on a transfer printing table, placing the metal foil on the glue pattern which is not completely dried, heating the transfer printing table to about 160 ℃, then pressing the metal foil and the T-Shirt for 15-20 seconds, cooling the T-Shirt for half an hour, separating the metal foil which is not ironed, and completing the cold ironing of the T-Shirt. The hot and cold stamping is famous for the effect of metal surface, but cannot print on regular surfaces such as plane and spherical surfaces and irregular surfaces like pad printing.
The gold stamping is carried out by adopting a pad printing mode, and the gold stamping is a brand new gold stamping process. The soft characteristic of the pad printing rubber head is utilized to extrude the gold stamping foil to be attached and move according to the surface profile of the workpiece, so that the effect of gold stamping on the irregular concave-convex surface can be realized. When the gold stamping foil is pressed on a non-plane surface for gold stamping, on one hand, due to poor ductility of the gold stamping foil, the gold stamping foil far away from the center of the rubber head cannot be attached to the surface of a workpiece to be gold stamped, so that the gold stamping effect is influenced; on the other hand, the wrinkles expanding outwards are generated, and the subsequent gold stamping effect is influenced if the wrinkles expand outwards to the unused area of the gold stamping foil. Therefore, the existing transfer printing and gold stamping process still needs to be improved and developed.
