In this embodiment, the plurality of traction brackets 12 of the paying-off device 1 of the warp knitting machine are used for traction and guiding the wires paid out by the plurality of groups of wire winding mechanisms 11, the wires enter the warp knitting forming device 2 to be knitted into lace sheets after passing through the traction rotating wheels 123 of the traction brackets 12, and the lace sheets are wound into rolls by the winding device 3. The wire inlet opening 121, the wire inlet channel 122 and the traction rotating wheel 123 included in the traction support 12 can facilitate an operator to place the wire on the traction support 12 in an initial stage, specifically, the wire falls on the traction rotating wheel 123 after passing through the wire inlet channel 122 from the wire inlet opening 121, and the traction rotating wheel 123 can freely rotate to facilitate the conveying of the wire. It should be noted that, in this embodiment, the height of the traction support 12 should be higher than the height of the wire outlet end of the wire winding mechanism 11, and the traction support 12 may be arranged in multiple rows and multiple columns in the horizontal direction and the vertical direction, and specifically, the number of the traction supports may be increased or decreased according to the number of wires. Because the wires enter the warp knitting forming device 2 after passing through the traction support 12, the wires can be effectively prevented from being wound, operators are also convenient to distinguish and place the wires with different functions and different positions, the operability of the warp knitting machine is effectively improved, and the failure rate is reduced.
Specifically, the traction bracket 12 includes a mounting base 124 and limiting strips 125 inserted and fixed on two sides of the mounting base, a wire inlet opening 121 is formed between the upper ends of the limiting strips 125 on two sides of the mounting base 124, a wire inlet channel 122 is formed between the middle parts of the limiting strips 125, and a traction rotating wheel 123 is rotatably mounted on the mounting base 124 and correspondingly connected with the inner sides of the lower ends of the limiting strips 125. The limiting bar 125 is composed of an arc part with an inward concave upper end, an arc part with an inward convex middle part and an arc part with an inward concave lower end. Meanwhile, the top end of the arc portion, which is concave inwards, of the upper end of the limiting strip 125 is further provided with an extension portion 126 extending outwards, the extension portion 126 can further facilitate an operator to place the wire in the traction support 12, and after the wire passes through the wire inlet opening 121 and the wire inlet channel 122, the wire can be effectively prevented from sliding out of the traction support 12 due to the fact that the wire inlet channel 122 is narrow.
