A vision-based digital inkjet printing method for warp knitted shoe uppers

Abstract

The present invention relates to the technical field of jet printing, in particular to a vision-based digital inkjet printing method for warp-knitted vamps, comprising the following steps: S1) setting a digital inkjet printing machine conveying guide belt according to the size of the shoe shape in the warp-knitted cloth sheet S2) collect the whole wide warp-knitted fabric vamp image, S3) establish corresponding virtual coordinates according to the collected image; S4) determine the standard AI shoe shape image file template set, through the selected mesh feature Identify the feature points of other shoe shapes, and adjust the angle of the shoe shape according to the angle and length deviation between the standard AI image template and the identified feature points; The angled images are matched to determine the exact position coordinates of the shoe mesh and the printing pattern, and the printing head is controlled to complete the printing. The present invention performs deviation correction processing on the shoe shape, adjusts the angle of the shoe shape, and then performs spray printing on the shoe shape, thereby improving the printing accuracy and production efficiency.

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, ...

AI Technical Summary

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.
