Laser pattern printing device

Abstract

The invention discloses a laser pattern printing device which comprises a rack. A paper tape transmission device formed by a plurality of driving wheels and used for transmitting a paper tape is arranged between a paper feeding device and a paper discharging device. The two driving wheels in the paper tape transmission device are a coating driving wheel and a coining driving wheel respectively. A container used for containing UV gloss oil is arranged below the coating driving wheel. A coating roll which coats the paper tape with the UV gloss oil evenly through the rotation of the coating roll to form a UV gloss oil layer is arranged inside the container. A laser pattern is arranged on the surface of a pattern coining roll. The pattern coining roll is used for coining the laser pattern on the UV gloss oil layer of the paper tape to form a laser pattern layer of the paper tape. A drying device used for drying a UV gloss oil pattern layer is arranged in the transmission direction of the coining driving wheel. By directly printing a laser anti-counterfeit pattern on the UV gloss oil layer, the laser pattern printing device improves production efficiency, lowers cost and enhances the anti-counterfeit property.

Description

[technical field] [0001] The invention relates to the field of laser printing, in particular to a laser pattern printing device. [Background technique] [0002] At present, the production cost of laser pattern transfer printing is high and the production of laser mold belt pattern is not flexible enough. The production requires a special process. First, the coating is transferred and then printed. The laser layer is under the printing layer, and it is easy to lose part of the laser effect. In-line production cannot be realized. Although there are also laser transfer devices on the market, they are all offline transfer and sheet transfer, and the transfer effect has a large distance limitation. The transfer accuracy is not high, the content is not rich enough, the production efficiency is low, and the process is very cumbersome. , the production cost is relatively high. [0003] There is a transfer layer of laser pattern or text on the traditional mold belt. The laser patte...

AI Technical Summary

Problems solved by technology

[0005] 1. The efficiency is low, requiring the hot stamping machine to be heated to a certain temperature, the heating time is long, and it cannot be connected, and cannot run at high speed

[0006] 2. The cost is high, the laser pattern needs to be printed on the mold belt, and then the hot stamping machine is used to transfer the laser pattern mold belt

[0007] 3. Low anti-counterfeiting, traditional hot stamping laser patterns are easy to be imitated
