WEFT THREAD LAYING DEVICE AND WEFT THREAD LAYING METHOD FOR WARP KNITTING MACHINE

A yarn guide coordination device comprises a mounting base (1). A group of parallel first guide rods (5) are vertically connected to the mounting base (1). Each of the first guide rods (5) is sleeved with a slidable sliding sleeve (9). The device further comprises a sliding block (6) connected between the sliding sleeves (9). A first push cylinder (2) and a second push cylinder (4) that are oppositely disposed are respectively connected to the mounting base (1) and the sliding block (6). A piston rod of the first push cylinder (2) is connected to a piston rod of the second push cylinder (4). The sliding block (6) is connected to a needle file (7). The needle file (7) is provided with several straight needles (8). By improving the structure of the yarn guide coordination device, motion strokes of the yarn guide coordination device, a weft thread laying vehicle, and a weft thread laying beam are reduced, a weft thread laying time is shortened, production efficiency is improved, and a weft thread laying requirement of a high-speed warp knitting machine is met.
