Visual-based warp-knitted vamp digital ink-jet printing method

Abstract

The invention relates to the technical field of jet printing, in particular to a visual-based warp-knitted vamp digital ink-jet printing method. The visual-based warp-knitted vamp digital ink-jet printing method comprises the following steps of (1) setting the rotating speed of a conveying guide belt of a digital ink-jet printing machine according to the size of a shoe type in a warp-knitted fabric sheet; (2) collecting a whole-width warp-knitted fabric sheet vamp image; (3) establishing corresponding virtual coordinates according to the collected image; (4) determining a standard AI shoe typegraph file template sleeve position, identifying the feature points of other shoe types through selected mesh feature points, and adjusting the angle of the shoe type according to a standard AI graphfile template and the identified feature points; and (5) collecting warp-knitting shoe type meshes and jet printing patterns, matching the warp-knitting shoe type meshes and jet printing patterns with an image obtained after angle adjustment to determine the accurate position coordinates of the shoe type meshes and jet printing patterns, and controlling a jet printing head to finish jet printing.By means of the visual-based warp-knitted vamp digital ink-jet printing method, the shoe type is subjected to correction treatment and is subjected to jet printing treatment after shoe type angle adjustment, so that the jet printing precision and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of jet printing, in particular to a vision-based digital ink jet printing method for warp knitted shoe uppers. Background technique [0002] With the overall improvement of today's world economic level, people's demand for clothing, textiles, etc. is becoming more and more individualized and diversified, which has brought a certain positive impact on the traditional textile industry, requiring that the manufacturing field must also be transformed into Multi-variety and small batch production process. [0003] The emergence of digital inkjet printing technology just meets and adapts to this new market demand. Digital inkjet printing technology is the product of the integration of advanced technologies such as precision machinery, computer and photoelectric integration, and is a major breakthrough in traditional printing technology. . [0004] In terms of digital inkjet printing of warp-knitted shoe uppers, ...

Problems solved by technology

[0004] In terms of digital inkjet printing of warp-knitted shoe uppers, the existing technology is mainly to pre-print on the platform, print the outline of the spray printing, and repeat the printing after pasting the cut pieces; Outline, and then carry out local pattern printing on the corresponding film, and need to use the projection sleeve template for positioning. However, when using the template for positioning, it takes a long time to adjust the template alignment, which consumes more labor and is more cumbersome to operate; and When the warp-knitted vamp is deformed, the typesetting on the computer and the pattern actually printed on the vamp will be translocated during the process, resulting in many problems such as inkjet printing not being able to proceed normally.
