Abstract
Description
Technical Field
[0001] The utility model relates to hot stamping equipment, in particular to an aluminized paper conveying mechanism of an in-line cold foil stamping machine. Background Art
[0002] In the printing industry, in order to achieve the effect that the surface of printed products has a metallic feeling, the hot stamping process is often adopted. The hot stamping process is divided into two types: hot stamping and cold stamping. The hot stamping process is to engrave the pattern to be hot stamped on the master plate, and through the heating method, the gold and silver patterns on the aluminized paper are laid on the surface of the printed product to achieve a three-dimensional effect. However, the hot stamping process has a fatal defect, that is, when stamping fine lines and large areas, the fine lines often break, and there will be problems of incomplete stamping and incomplete stamping in large-area stamping. The cold stamping process is a process of sticking the graphics and texts on the hot stamping aluminized paper through glue, which can solve the problems of incomplete stamping of fine lines and large areas.
[0003] Many parts of the products to be printed that need to be hot stamped may only have a small area. When the traditional in-line cold foil stamping machine is used for hot stamping, the conveying speed of the aluminized paper is usually the same as that of the products to be printed. Therefore, when there are many blank areas on the printed products, a large amount of aluminized paper will be wasted. At present, some in-line cold foil stamping machines reduce the amount of aluminized paper used by setting a skip roller to convey the aluminized paper and the products to be printed at different speeds, so that when the area to be hot stamped of the products to be printed moves to the hot stamping station, the aluminized paper is conveyed again. However, this kind of skip roller is usually difficult to replace. When hot stamping different products to be printed, since the positions and widths of the areas to be hot stamped of different products to be printed are different, the amount of aluminized paper used is also different. If a single skip roller is used to convey the aluminized paper, some waste will be caused. Summary of the Utility Model
