A yarn feeding system for a double-needle bed flat yarn warp knitting machine

Abstract

The invention discloses a double needle bed flat yarn warp knitting machine yarn supply system. The system integrates the production of flat yarn and the weaving production, which is within the technical field of warp knitting equipment. The system provides a double-needle bed flat yarn warp knitting machine yarn supply system which integrates the production of flat yarn and the weaving production, so that the polyolefin film industrial package material which is relatively easy to obtain can be directly selected in the production process. As the beginning of the production of warp knitting machines, production equipment such as cold drawing of film, hot-cutting of split film, and hot drawing of flat wire is cooperated with conveyors such as flat yarn synchronous transmission, flat yarn breakage detection, flat yarn single yarn tension compensation, etc. At the same time, two sets of symmetrical yarn paths of warp yarn and weft-knitted flat yarn are provided to form a flat yarn supply system for integrating and producing warp knitting yarns. The system greatly shortens the production process of flat yarn warp knitting and improves the efficiency of weaving manufacturers in the development and production of flat warp knitting products.

Description

technical field [0001] The invention relates to a yarn supply system using flat yarn as a raw material, in particular to a yarn supply system for a double-needle bed flat yarn warp knitting machine, which belongs to the technical field of warp knitting equipment. Background technique [0002] Warp knitting technology, with its unique loop forming form and the knitting characteristics of various large-scale mesh structures, makes warp knitting machines with low gauge and large gauge suitable for the production of industrial raw materials such as sunshade nets, woven bags, and fishing nets. The field can be rapidly expanded and applied. Especially with the emergence of multifunctional film materials composited with polyolefin resin and various anti-aging materials, after heating, stretching, cutting or spinning, and then warping by a special flat warping machine, it is provided to the warp knitting machine. Machine for weaving, can produce a variety of single-layer and double...

AI Technical Summary

Problems solved by technology

[0003] The high speed and high efficiency of warp knitting machine weaving largely depends on the good warping process before weaving. The production of flat yarn warp knitting products is organized by segmented yarn supply, and the assembly line is designed in the order of yarn separation, warping, and weaving. Since flat yarn raw materials are usually difficult to order directly from the market in the form of ordinary raw materials, weaving manufacturers can only purchase special Advanced plastic extruders, film splitting devices, flat wire heating devices, stretching machines and stress relief devices, flat wire warping machines and other series of processing equipment, resulting in too long production lines, many types of equipment, large floor space, and high input costs. Moreover, the raw material ratio and production process of polyolefin film materials are relatively complicated, and most weaving manufacturers are not familiar with it and it is difficult to master it. The single yarn supply of the creel shows great differences and obvious particularities. Therefore, most weaving manufacturers are not willing to choose to start with the production of polyolefin materials, nor are they willing to choose long production lines and purchase too many types. Therefore, it hinders the large-area application of polyolefin flat filament materials on double-needle bed warp knitting machines to a certain extent.
