Embodiment 1

[0034] A needle selection device for a latch needle warp knitting machine.

[0035] Refer to attached Figures 1 to 6 , The device includes a needle bed 1, a latch needle 2, a cover plate 3, an insertion support 4, a support 5, and a control mechanism 6. Wherein, the needle bed 1 is provided with a row of needle grooves 7 according to the machine number requirements, and the latch needles 2 which can move up and down are installed in the needle grooves 7, and the latch needles 2 have needle butts. The cover plate 3 is installed on the needle bed 1 and is provided with a slot 8, the inserting support 4 is installed in the slot 8 and can move back and forth, and the upper inserting support 4-1 and the lower inserting support 4-2 can clamp The needle butt, the support member 5 is installed under the latch needle 2, and the control mechanism 6 can control the movement of the insertion support member 4.

[0036] In this embodiment, the cover plate 3 is installed on the needle bed...

Embodiment 2

[0041] A needle selection method for a latch needle warp knitting machine.

[0042] The method is applied to the needle selection device of the latch needle warp knitting machine in embodiment 1, which is specifically:

[0043] During the rising or falling process of the cover plate 3, the latch needle 2 stops synchronously moving with the cover plate 3 and stays at the corresponding position by adjusting the insertion position of the upper and lower inserting support members 4-2, specifically divided into:

[0044] When the cover plate 3 rises, the lower inserting support 4-2 is inserted under the needle butt, and the latch needle 2 rises synchronously with the cover plate 3; when the lower inserting support 4-2 is not inserted under the needle butt, the latch needle 2 does not The cover plate 3 rises synchronously and stays at the corresponding position;

[0045] When the cover plate 3 descends, the upper inserting support 4-1 is inserted above the needle butt, and the latc...

Abstract

The invention discloses a needle selection device and method for a latch needle warp knitting machine, which comprises a needle bed, and the needle bed includes a plurality of needle grooves arranged in rows according to machine number requirements, and a needle groove which can move up and down is installed in the needle groove. Latch needles, the latch needles are provided with needle butts, and a cover plate is installed on the needle bed, and a slot corresponding to the needle groove is provided on the cover plate, and a front and back movement is installed in the slot. The inserting support includes an upper inserting support and a lower inserting support, the needle butt is clamped between the upper inserting support and the lower inserting support, and a support is installed under the latch needle. After adopting the above-mentioned invention, the latch needle warp knitting machine can adjust the height of each knitting needle according to the process requirements when knitting, and can optionally weave into loops, tucks, floating threads or part of the knitting needles to participate in knitting, etc., which enriches the The pattern type of the latch needle warp knitted fabric, and the invention has the advantages of simple structure, convenient operation, wide adjustment range and high selectivity, which is beneficial to the development and trial production of the new latch needle warp knitted fabric.

Description

technical field [0001] The invention relates to the technical field of warp knitting machines, in particular to a needle selection device and method for a latch needle warp knitting machine. Background technique [0002] The warp knitted fabric is a knitted fabric formed by inserting one or several groups of warp yarns arranged in parallel into a row of knitting needles along the longitudinal direction on the warp knitting machine, forming loops synchronously and interlacing each other. The loop forming parts of the warp knitting machine mainly include knitting needles, guide needles and sinkers. At present, the knitting needles on the warp knitting machine are all installed on the needle bed, and reciprocate up and down together with the needle bed. The warp knitting machine has not been equipped with a device for selecting individual knitting needles and controlling their up and down movement, and cannot control the movement of single or multiple knitting needles. [000...
