Method and device for manufacturing color tufting product

Abstract

The invention relates to a method and a device for manufacturing a color tufting product, belonging to the technical field for manufacturing the color tufting product. The solved technical problem in the invention is to provide the method and the device for manufacturing the tufting product with colorful jacquards, wherein high piles of the tufting product completely cover low piles; the technical scheme for solving the technical problem is as follows: a non-vector pattern is adopted and a tufting faller or a tufting base cloth is scanned line by line according to pattern pixel points rearranged in rows when at different positions, each tufting faller corresponds to effective pixel points and invalid pixel points at different positions in each tufting process, so that high-feed piles and low-feed piles are in non-linear distribution on the surface of the tufting product; and the method and the device are mainly used for manufacturing the color tufting product.

Description

technical field [0001] The invention relates to a method and a device for manufacturing colored tufted products, and belongs to the technical field of manufacturing colored tufted products. Background technique [0002] The commonly used method for manufacturing colored tufted products is: each needle of the tufting loom maintains a fixed position relative to each pixel of the design pattern, the high and low piles are linearly distributed along the tufted base fabric, and the high piles cover low The fleece can only be half covered. [0003] At the same time, the scanned pattern is not re-divided according to the gray value of the pixel points, and each row in the pattern has more than one effective pixel point of gray value, so the existing technology can only produce a relatively simple jacquard tufting product. [0004] The tufted looms currently on the market mainly use high and low pile structures to achieve the jacquard effect. This kind of loom weaves the needles i...

Problems solved by technology

For example, after tufting a high pile, immediately tuft a low pile and then tuft a high pile, because the position of the tufting yarn feeding device and the needle is far away, and the yarn itself has elastic shrinkage, the result of the yarn feeding It cannot be reflected on the needle in time, the high-feeding yarn has not reached the expected pile height, and the bottom-feeding yarn has not reached the proper pile height

[0008] Therefore, the existing tufting looms can only knit some single-color or two-color or three-color simple patterns, and for those products with complex patterns and large color changes, they cannot be knitted, which is the reason why complex pattern products cannot be knitted. Mainly, the existing loom cannot quickly and accurately change the yarn that matches the color of the pattern, that is, each knitting needle or weaving action cannot keep up with the desired position and speed

Even some high-performance looms can keep up, but when the required position is reached within the required time, the length of the yarn during knitting is inconsistent with the required length, which is caused by not adjusting the amount of yarn feeding according to the moving distance during knitting
