Problems solved by technology

[0003] Usually in the production process, in order to improve the production efficiency and product qualification rate, it is necessary to reduce the processing steps as much as possible to achieve the best processing effect, while the traditional hot stamping process has to be separated because of the products of holographic hot stamping and text embossing hot stamping. For processing, the holographic or embossed hot stamping text should be applied first, but no matter whether the holographic or embossed hot stamping is first applied, it is easy to cause slight scratches to the hot stamping part during the processing, which will affect the product quality, and there will be two times in the two processes Process loss, the increase in loss directly leads to a decrease in the product qualification rate. In addition, the hot stamping process needs to perform plate alignment and calibration on the honeycomb plate dedicated to hot stamping. Two times of hot stamping need to be installed and corrected twice. The processing time will be doubled, which is very unfavorable for efficient production
[0004] Although the current technology has also appeared the hot stamping plate and related technology that can complete holographic hot stamping and concave-convex hot stamping in the same process, such as the hot stamping process and hot stamping plate disclosed in patent documents CN101693427 A and CN204977805 U, but, due to the general holographic hot stamping area It is far away from the concave-convex hot stamping area, mostly more than 50mm, so there is a difference in temperature between holographic hot stamping and ordinary hot stamping. The required temperature and pressure are greater than those required for holographic hot stamping, and the existing holographic hot stamping areas are all a very flat plane, so that under high temperature and high pressure, the air in the holographic hot stamping area is very smooth. Difficult to remove from the hot stamping plate instantly, if the air in the holographic hot stamping area cannot be removed instantly, it will easily cause hot stamping mist in the holographic hot stamping area, which will seriously affect the hot stamping quality of the product

Embodiment 1

[0039] Such as Figure 1-2 As shown, the hot stamping plate of the present invention includes a plate base 10, on which a holographic hot stamping area 100 and a concave-convex hot stamping area 200 are protrudingly arranged, and between the holographic hot stamping area 100 and the concave-convex hot stamping area 200 The spacing distance is less than or equal to 25mm. More specifically, the holographic hot stamping area 100 and the concave-convex hot stamping area 200 are all carved on the 8mm thick copper plate base by an electric engraving machine. Keep the thickness of the pattern part unchanged at 8mm, and use an electric engraving machine to carve out the parts that do not need hot stamping. At the same time, when engraving, the center of the holographic hot stamping area 100 is raised to form a pot-bottom-like surface, that is, the center is high and the surrounding is low. Concave-convex bronzing area 200 is to engrave and form a downward concave pattern on its surfac...

Embodiment 2

[0044] Such as Figure 4 As shown, the bronzing machine of the present invention includes a paper feeding table 1, a paper feeding table 2 connected with the paper feeding table 1, a positioning pull gauge 3 arranged above the end of the paper feeding table 2, and under the action of the positioning pull gauge 3 , can position the paper surface on the paper feeding table 2; the positioning front gauge 4 arranged at the end of the paper feeding table 2, under the action of the positioning front gauge 4, can position the paper laterally; that is to say, before positioning Under the synergistic effect of the gauge 4 and the positioning pull gauge 3, the paper has a precise and fixed conveying position, which is fully prepared for the subsequent bronzing process; The hot stamping plate above as described in embodiment 1, is installed with the hot stamping plate, is used for the honeycomb plate 6 that the hot stamping plate is heated, is arranged on the paper gripper tooth bar 7 be...

Embodiment 3

[0047] Present embodiment is the bronzing method that utilizes the bronzing machine in embodiment 2 to carry out bronzing, and this bronzing method specifically comprises the following steps:

[0048] S1, the installation of hot stamping version

[0049] The hot stamping plate is firmly locked on the honeycomb plate by the self-locking device, and a corresponding number of hot stamping plates are installed according to the needs of the hot stamping pattern;

[0050] S2. Installation of cellular version

[0051] Install the honeycomb version with the hot stamping version at the installation position of the honeycomb version of the hot stamping machine, and lock it;

[0052] S3, installation of anodized aluminum

[0053] Place the anodized aluminum in the anodized aluminum unwinding device. When placing it, ensure that the direction of the anodized aluminum being gilded is consistent with the direction of the hot stamping plate, and make the holographic hot stamping area of ​​...

Abstract

The invention discloses a gilding plate, a gilding press and a gilding method, wherein the gilding plate comprises a plate base; a holographic hot stamping area and a concave-convex gilding area are arranged on the plate base in a bulging manner; the distance between the holographic hot stamping area and the concave-convex gilding area is smaller than or equal to 25 mm; the center of the holographic hot stamping area is bulged to form a pot-bottom-shaped surface; and a downwardly sunk pattern is formed in the surface of the concave-convex gilding area. As the holographic hot stamping area and the concave-convex gilding area are arranged on the same plate base at the interval, holographic hot stamping and concave-convex gilding of electrochemical aluminum can be fulfilled in the same process, that is, the production efficiency is greatly improved; and meanwhile, as the distance between the holographic hot stamping area and the concave-convex gilding area is smaller than or equal to 25 mm, the temperature change between the holographic hot stamping area and the concave-convex gilding area is small, and the gilding effect is effectively guaranteed.

Description

technical field [0001] The invention relates to hot stamping printing technology, in particular to a hot stamping plate, a hot stamping machine and a hot stamping method Background technique [0002] In the post-press process of trademark processing, many products are inseparable from the combination of holographic hot stamping and text embossed hot stamping. Whether it is holographic hot stamping or text embossed hot stamping (with embossed metal effect), its purpose is mainly to enhance Product anti-counterfeiting function and text decoration function. The commonly mentioned holographic hot stamping includes positioning hot stamping and non-positioning hot stamping. The positioning hot stamping pattern is uniform and has anti-counterfeiting function. The non-positioning hot stamping pattern is distributed regularly, and the anti-counterfeiting effect is not good. This technology is mainly for positioning hot stamping. The traditional method is to separate the product to t...
