Embodiment 1

[0032] See Figure 1 to Figure 5, the production system of the low-cost high-quality warp-knitted unidirectional fabric of the present embodiment adopts a multiaxial warp knitting machine, and the multiaxial warp knitting machine includes a weft yarn needle block group, a weft laying trolley, a conveying device 4, and a yarn guide needle block 5, knitting head, constant tension yarn supply device 6 and auxiliary device 7; yarn guide needle block 5 corresponds to the weft yarn needle block group, and the pitch of yarn guide needle block 5 is the same as that of the weft yarn needle block group needle block; The needle block group includes standard needle block 1, A-type needle block 2 and B-type needle block 3 with the same width. X needles are set on each of the three needle blocks; Arrange X needles with a diameter of Dmm at equal distances; the setting position of the X needles on the A-type needle block 2 is based on the standard needle block 1, and each needle moves in the...

Abstract

The invention discloses a production system for low-cost and high-quality unidirectional warp knitted fabric. The production system adopts a multi-axial warp knitting machine, wherein a weft yarn needle holder group comprises standard needle holders, type A needle holders and type B needle holders, the holders are in consistent width, and X needles are arranged on each of the three kinds of needle holders; the standard needle holders and the type A needle holders as well as the standard needle holders and the type B needle holders are arranged on two sides of a weft laying area respectively, and the standard needle holders and the type B needle holders are arranged at intervals according to the weft laying width; the standard needle holders and the type A needle holders are arranged at intervals according to the weft laying width after rotating for 180 degrees; the same kind of needle holders is arranged in each weft laying width. With adoption of the production system, high-quality unidirectional fabric can be produced only by making cost-controllable change on the conventional multi-axial warp knitting machine, and the system operates reliably.

Description

technical field [0001] The invention relates to a low-cost and high-quality warp-knitted unidirectional fabric production system. Background technique [0002] Reinforced fiber unidirectional fabrics, such as carbon fiber unidirectional fabrics, are widely used in industry due to their superior performance, especially in wind power generation blades. Theoretically, unidirectional fabric can be woven by multiaxial warp knitting machine or biaxial warp knitting machine. If an ordinary biaxial warp knitting machine is used to produce, but the cutting speed of the biaxial warp knitting machine and the transmission speed of the weft needle block are inconsistent, the force on the selvedge after cutting is relatively large, resulting in a wavy edge, commonly known as the fungus edge , affecting the quality of unidirectional fabric, so the ordinary biaxial warp knitting machine is only suitable for making unidirectional fabric with a small width, or improving the biaxial warp knit...
