Embodiment 1

[0032] See Figure 1 to Figure 5, The production system for low-cost and high-quality warp knitted unidirectional fabrics in this embodiment adopts a multi-axial warp knitting machine. The multi-axial warp knitting machine includes a weft 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 needle block group, and the needle pitch of yarn guide needle block 5 is the same as that of the weft needle block group needle block; weft yarn 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 all three needle blocks; on the standard needle block 1, the center line of the needle block goes to both sides. Arrange X needles with a diameter of Dmm at equal distances; the setting positions of X needles on the A-type needle bloc...

Abstract

The invention discloses a production system of low-cost and high-quality warp-knitted unidirectional fabrics, which adopts a multi-axial warp knitting machine; X needles are arranged on the needle block; the standard type needle block and the A type needle block, as well as the standard type needle block and the B type needle block are respectively arranged on both sides of the weft laying area; the standard type needle block and the B type The needle blocks are set according to the interval of the weft laying width; the standard type needle block and the A-type needle block are both rotated 180° and set according to the interval of the weft laying width; the same needle block is set in each weft laying width. The present invention only needs cost-controllable changes to the existing multi-axial warp knitting machines, can realize the production of high-quality unidirectional fabrics, and has reliable operation of the equipment.

Description

technical field [0001] The invention relates to a production system for low-cost and high-quality warp knitted unidirectional fabrics. Background technique [0002] Reinforcing fiber unidirectional cloth, such as carbon fiber unidirectional cloth, is widely used in industry due to its superior performance, especially in wind power generation blades. The unidirectional fabric can theoretically be woven with a multiaxial warp knitting machine or a biaxial warp knitting machine. If it is produced by an ordinary biaxial warp knitting machine, the cutting speed of the biaxial warp knitting machine and the transmission speed of the weft needle block are inconsistent. , affecting the quality of the unidirectional fabric, so the ordinary biaxial warp knitting machine is only suitable for making a small width unidirectional fabric, or improving the biaxial warp knitting machine, but the characteristics of the biaxial warp knitting machine itself, the cost of improvement It is very ...
