Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing technology, specifically to a film material printing device. Background Technology
[0002] Flexographic printing, or simply flexographic printing, is a printing method that uses a flexible plate and an anilox roller to transfer ink. It is a type of letterpress printing, characterized by the image area on the printing plate being higher than the blank area. Digital printing, on the other hand, is the digitalization of printing technology. Unlike flexographic printing, which requires plate-making, digital printing allows for printing from a single sheet, eliminating the need for plate-making, and enabling variable and on-demand printing. Traditionally, the printing industry has largely adopted flexographic printing due to its low cost, high precision, and high efficiency. However, due to market demands, printed designs often have variable data. Using flexographic printing would require multiple plate-making and changes, making it less cost-effective. Therefore, digital printing is now widely used for variable data portions of printed designs.
[0003] For variable data printing of membrane materials, which have high elasticity, the printed pattern is prone to deformation and distortion. It is usually necessary to print a coating on the printing medium to keep the elasticity of the membrane material relatively constant before printing the variable data. After printing, another coating is usually printed on the printed pattern to protect it. For printing on film materials, flexographic printing alone cannot handle the printing of variable data. Digital printing alone is costly and not cost-effective due to the high cost of digital printers. Another approach is to first print the coating on the entire roll of printing media using flexographic printing. For print jobs containing both non-variable and variable data, a coating layer can be printed first, and the non-variable data can be printed first. Then, the printing media with the bottom coating and / or the non-variable data pattern can be placed on digital printing equipment for the variable data portion. Finally, the entire roll of printing media can be sent to flexographic printing equipment to print the top coating. However, this method is not only inefficient but also prone to color misregistration. Furthermore, companies that already own digital or flexographic printing equipment need to replace or purchase new equipment, making it difficult to flexibly adapt to order requirements.
[0004] In view of this, the present invention provides a film material printing device that integrates a flexographic printing module and a digital printing module, enabling one-stop operation of flexographic printing and variable data printing, significantly improving efficiency and effectively reducing costs. For enterprises that originally only had digital printing equipment or only had flexographic printing equipment, they can upgrade their machines by adding flexographic printing modules or digital printing modules as needed. Alternatively, when no upgrade is needed, the redundant modules can be removed, allowing for more flexible production transformation and saving the cost of purchasing new equipment while improving production efficiency.

[0005] The present invention aims to provide a membrane material printing device to overcome the shortcomings of the prior art. The technical problem to be solved by the present invention is achieved through the following technical solution.
[0006] A film-type material printing apparatus includes a digital printing module, a first flexographic printing module, a second flexographic printing module, a feeding module, and a receiving module. The feeding module carries and continuously releases the printing medium. The first flexographic printing module receives the printing medium from the feeding module and performs flexographic printing of the underlayer coating on the printing medium. The digital printing module receives the printing medium from the first flexographic printing module and performs variable data digital printing on the printing medium on the printing platform.

The receiving module receives the printing medium from the second flexographic printing module and rewinds and organizes the printing medium.
[0007] Preferably, the first flexographic printing module includes a first flexographic printing unit, a first UV lamp, and a plurality of first flexographic printing guide rollers. The first flexographic printing guide rollers are used to receive and carry the printing medium released from the feeding module and to guide and convey the printing medium. The first flexographic printing unit is used to perform flexographic printing of the underlayer coating on the printing medium on the first flexographic printing guide rollers. The first UV lamp is used to irradiate the underlayer coating on the printing medium to make it dry and fix on the printing medium.
[0008] Preferably, the digital printing module includes a printhead printing unit, a printing platform, and several digital printing guide rollers. The digital printing guide rollers are used to receive printing media from the first flexographic printing module and guide and convey the printing media.

The second flexographic printing guide rollers are used to receive and carry the printing medium from the digital printing module and to guide and convey the printing medium. The second flexographic printing unit is used to perform flexographic printing of the surface coating on the printing medium on the second flexographic printing guide rollers. The second UV lamp is used to irradiate the surface coating on the printing medium so that it dries and fixes on the printing medium.

During printing, the first flexographic printing module uses flexographic printing to complete the printing of the undercoat layer on the printing medium, ensuring the elasticity of the film-like printing medium remains relatively constant. Then, the printing medium with the undercoat layer is conveyed to the digital printing module, where variable data digital printing is performed on the undercoat layer, effectively preventing distortion of the printed image. The printing medium with the variable data digital printing completed is then conveyed to the second flexographic printing module, where the surface coating is printed using flexographic printing, thus providing a protective sealing layer for the printed image. The feeding module and receiving module are equipped with a deviation correction device and a corona treatment device. The deviation correction device is used to correct the deviation of the printing medium to prevent it from becoming skewed during the conveying process. The corona treatment device is used to perform corona treatment on the surface of the printing medium to enhance the surface tension of the printing medium, thereby improving the adhesion of the printing medium and facilitating the formation of a firm adhesion of ink on the surface of the printing medium.
[0013] This utility model provides a film material printing device that integrates a flexographic printing module and a digital printing module, enabling one-stop operation of flexographic printing and variable data printing, significantly improving efficiency and effectively reducing costs.
