Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordi...

The invention relates to the technical field of weaving, in particular to a method for determining the optimal shift of a weft laying device. The method comprises the following steps of determining a qualitative relationship between the shift and yarn loss according to a weft laying path; determining the actual maximum vehicle speed, and if the actual maximum vehicle speed X is smaller than the theoretical maximum vehicle speed, adjusting the shift according to the actual maximum vehicle speed; and determining the maximum frequency of the weft laying device, and adjusting the shift according to the maximum frequency. According to the method, the qualitative relation between the shift and the weight of a waste silk is determined firstly, the positive correlation between the weight of the waste silk and the shift is determined, and therefore the improvement thought that the shift is reduced to reduce the weight of the waste silk is determined, and by determining the frequency of the weft laying device and guaranteeing the maximum actual vehicle speed, production is considered, and the amount of the waste silk is saved. Compared with the prior art, a clear solution thought is provided, a fuzzy concept is clarified, and an effective solution is provided for parameter adjustment in enterprise production.
Description
technical field [0001] The invention relates to the technical field of weaving, in particular to a method for determining the optimal travel distance of a weft laying device. Background technique [0002] The weft laying device is used in the weaving process of the fabric. In order to make full use of the performance of the fabric and reduce the bending of the yarn, in related technologies, such as figure 1 As shown, the weft laying device is often used to first lay the yarn on the composite material through the conveyor chain 10, and then bind the multi-layer yarns in various directions on the composite material through the high-speed warp knitting machine 20, after warp knitting, the yarns on both sides of the cloth Use the cutting knife 30 to trim the edge, roll up the trimmed cloth, and collect the excess waste silk into the waste silk box, which realizes the continuous production of high-performance composite material cloth. In the above continuous production process, ...
