Once forming mechanism of multiple gold stamping processes

Abstract

A once forming mechanism of multiple gold stamping processes comprises an alumite unwinding system, a gold stamping plate roller, an embossing roller and an alumite recovery system. Each automatic tension adjusting alumite unwinding roller is provided with a positioning gold stamping alumite unwinding roller, a uniform step / hop step gold stamping alumite unwinding roller and a continuous gold stamping alumite unwinding roller which are respectively independent. A continuous gold stamping tape, a uniform step / hop step gold stamping tape and a positioning gold stamping tape are respectively recovered by the three automatic tension adjusting alumite unwinding rollers. The gold stamping plate roller is respectively correspondingly provided with a continuous gold stamping plate, a uniform step / hop step gold stamping plate and a positioning gold stamping plate in the axial direction. The once forming mechanism integrates multiple gold stamping processes such as continuous gold stamping, uniform step / hop step gold stamping and positioning gold stamping, finishes the multiple gold stamping processes in one time, saves printing places, reduces device volume, greatly improves production efficiency, and reduces device cost.

Description

technical field [0001] The invention relates to a printing machine, in particular to a forming mechanism integrating continuous hot stamping, uniform step / skip hot stamping, and positioning hot stamping at one time. Background technique [0002] As a very important surface finishing process in the packaging and printing process, the hot stamping process has the dual functions of increasing the added value of printed products and efficient anti-counterfeiting precisely because of its high technical difficulty and high quality requirements. In general packaging printing, there are situations where multiple hot stamping processes are required on one packaging surface, especially the situation where the position, shape and characteristics of the hot stamping patterns are quite different. If the selection is not appropriate, the hot stamping accuracy will be biased, the stability of the hot stamping accuracy is poor under the high-speed hot stamping state, and the utilization rat...

Problems solved by technology

In general packaging printing, there are situations where multiple hot stamping processes are required on one package surface, especially the situation where the position, shape and characteristics of the hot stamping patterns are quite different. If the selection is not appropriate, the hot stamping accuracy will be biased, the stability of the hot stamping accuracy is poor under the high-speed hot stamping state, and the utilization rate of anodized aluminum is not high

The current situation is that the hot stamping operation is carried out sequentially for patterns of different positions or shapes in the form of an assembly line. The disadvantages are high equipment cost, large space occupation, and long time consumption. Since the assembly line is very long, no faults are allowed in the middle, so the traditional The hot stamping method is not conducive to the reduction of quality failure rate
