Group-type logistics bidirectional holographic positioning overprinting machine

Abstract

The invention relates to a group-type logistics bidirectional holographic positioning overprinting machine, which belongs to the technical field of anti-counterfeit printing equipment. The overprinting machine is characterized by consisting of an unwinding device, a photoelectric recognition control device, an electric control base, a traction device, an overprinting device and a winding device, wherein the winding and unwinding devices are integrated with the electric control base; the overprinting device is positioned above the electric control base; the winding and unwinding devices are positioned on both sides of the overprinting device; the photoelectric recognition control device is arranged in front of the overprinting device and matched with the unwinding device; the unwinding device consists of a group of reel printing stock unwinding devices and multiple groups of reel holographic anti-counterfeit film unwinding devices; each unwinding device corresponds to a group of photoelectric recognition control devices; the unwinding modes of the multiple groups of reel holographic anti-counterfeit film unwinding devices are independent unwinding; and group sequence arrangement patterns correspond to preserved overprinting regions of reel printing stocks one by one. The equipment of the invention has the advantages of realizing correct and continuous overprinting, reducing rejection rate, shortening production period, effectively lowering production cost and greatly improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting printing equipment, and in particular relates to a group logistics two-way holographic positioning overprinting machine, which is specially used for overprinting and printing logistics markers. Background technique [0002] At present, positioning holographic overprinting on the roll substrate can only achieve one-way positioning transfer, that is, the position of the holographic pattern on the substrate is fixed, but the content is random. The continuous overprinting device in the prior art mainly realizes continuous paper feeding of continuous substrates (single sheets) by setting a continuous paper feeding mechanism, and realizes continuous printing with roll anti-counterfeiting film. For example: [0003] The Chinese patent with the publication number CN201169119 discloses a web unit-type hot stamping machine, which is composed of a web unwinding device, a paper storage device, a ...

AI Technical Summary

Problems solved by technology

[0004] Its main shortcomings are: 1) The hot stamping pattern is single, not a specific pattern, and it cannot realize logistics hot stamping, nor can it realize group hot stamping in which multiple groups of coils are hot stamped at the same time; 2) Each hot stamping unit only It can be hot stamped for one pattern or one size. For different patterns or different sizes required by special production, it can only be completed by adding multiple sets of hot stamping units. The production efficiency is low and the deviation of hot stamping is large; 3) Turn on the machine When multiple hot stamping units operate at the same time, the production cycle is long, and the coil substrate and aluminum foil are wasted during the production process; 4) During the operation of the equipment, the stripped aluminum foil is not properly and effectively discharged, and the finished product and waste foil Winding in the same direction at the same time, the waste foil falling will easily lead to a decrease in yield and safety hazards
