Abstract

The invention provides a tipping paper gravure online fine gold stamping device and gold stamping process. The device is mounted between a final-stage printing color set of a gravure press and a glazing machine unit. The device comprises a gravure cold stamping machine rack. Paper guide rollers are mounted on the two sides of the lower portion of the gravure cold stamping machine rack. A glue tank, a cold stamping plate roller set, a pre-curing UV lamp, a cold stamping press roller set, a curing UV lamp set, a winding machine and an unwinding machine are mounted in the gravure cold stamping machine rack from bottom to top in sequence. The winding machine and the unwinding machine are used in cooperation to complete winding and unwinding of a cold stamping film. The cold stamping plate roller set coats cold stamping glue to tipping paper. The cold stamping press roller set laminates the tipping paper with the cold stamping film to complete transfer of the gold stamping effect without aheating device. Energy consumption is reduced, and the overprinting effect is accurate.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to an on-line fine bronzing device for tipping paper gravure printing and a bronzing process. Background technique [0002] Cigarette pine paper is a special industrial paper and one of the main materials for tobacco packaging. With the improvement of consumption level, the decoration process on the surface of tipping paper is becoming more and more refined. Most of the high-end tipping paper will adopt bronzing process to improve the product grade. [0003] At present, the bronzing of tipping paper basically adopts hot stamping process, because the effect coating on the bronzing foil will be transferred to the tipping paper only under certain temperature and pressure. Cigarette pine paper is generally very thin. To stamp on such a thin paper, a high stamping pressure is required. The stamped lines are thick and the product is not fine enough. [0004] Cigarette pine ...
