Technical Field

[0001] This utility model belongs to the field of paper packaging material processing technology, and in particular relates to a multicolor UV printing device based on paper packaging materials. Background Technology

[0002] For the printing process of paper packaging materials, inkjet modules are used for spraying, and a post-UV curing module is used for rapid curing. For multi-color printing, a corresponding number of inkjet modules and UV curing modules need to be arranged. When multi-color printing is required for different needs, the existing printing equipment cannot be quickly adapted, which affects the scope of application. At the same time, if too many colors are required, it will cause the problem of occupying too much space. Summary of the Invention

By integrating the spraying and curing functions of a single color into a separate printing module, and by assembling it in a stacked manner, the device can assemble the corresponding number of printing modules according to the required color requirements. This facilitates installation, reduces space occupation, and greatly improves the applicability of the printing device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
