Laser engraving and printing process as well as equipment for implementing laser engraving and printing process

Abstract

The invention provides a laser engraving and printing process as well as equipment for implementing the laser engraving and printing process, and relates the field of printing. The laser engraving andprinting process comprises the following steps: S1, selecting a substrate; S2, analyzing the pore structure of the substrate; S3, manufacturing a screen plate for printing through color separation; S4, engraving a pattern by using a laser; S5, carrying out printing processing; and S6, carrying out paint spraying, polishing and grinding. The laser engraving and printing process provided by the invention has the beneficial effects that through the analysis of the structure of the substrate, the laser micro-engraving treatment on the surface of a to-be-processed product, and the printing in a micropore formed by laser engraving, slurry can penetrate into the substrate according to the set pattern and the color fading possibility of the pattern can be lowered; through the design, the continuous production can be achieved; and the color pattern of the printing product can be richly changed. The laser engraving and printing equipment comprises a laser engraving device, a printing device anda drying device which are connected in sequence, wherein the drying device comprises a multi-stage drying device and a total drying device; and a stable chemical bond is formed between the slurry andthe substrate, and prevented from falling off easily during use.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a laser engraving printing process and equipment for implementing the process. Background technique [0002] With the development of personalized home decoration and furniture design, the use of personalized wall coverings, the use of natural wood products and PU products are becoming more and more widely used. [0003] (1) Products based on felt cloth: [0004] At present, there are many types of wall coverings on the market, mainly four-layer structure: fiber hot-melt film + spunlace non-woven fabric + fiber hot-melt film + embroidery / jacquard / customized screen (from bottom to top), the surface pattern can be completely according to Design to choose or customize, thickness between 0.5-2mm. For some soft decorations that require sound insulation, such as various music and vocal practice fields, and houses near the road, conventional wall coverings cannot meet the needs. T...

AI Technical Summary

Problems solved by technology

[0011] Felt cloth products, wood substrates and PU products have the following defects: First, the proportion of wall covering and sofa publishing products in the furniture market is getting higher and higher. Changes, and even customized fabrics to meet the overall design requirements; secondly, compared with ordinary paint for walls and wall coverings, compared with wooden furniture and fabric furniture, the colors and patterns are monotonous and lack of personality; finally, home improvement The surface of medium PU products is printed, and the pattern will be worn after the product is used for a period of time
