Needle selection device and method of latch needle warp knitting machine

Abstract

The invention discloses a needle selection device and method of a latch needle warp knitting machine. The device comprises a needle bed, the needle bed comprises multiple needle grooves which are formed in row according to demands of machine numbers, and latch needles capable of moving up and down are installed in the needle grooves; the latch needles are provided with needle butts, a cover plateis installed on the needle bed, and insertion grooves corresponding to the needle grooves are formed in the cover plate; insertion support parts capable of moving front and back are arranged in the insertion grooves and include the upper insertion support parts and the lower insertion support parts, the needle butts are clamped between the upper insertion support parts and the lower insertion support parts, and supporting parts are installed below the latch needles. By adopting the needle selection device, when the latch needle warp knitting machine conducts knitting, according to technical requirements, the height of each knitting needle can be adjusted, loop formation, loop gathering, thread floating and a mode that partial knitting needles are involved in knitting can be selected, and the pattern kind of latch needle warp knitting fabric is enriched. The needle selection device is simple in structure, convenient to operate, wide in adjustment range, high in selectivity and beneficial to development and preproduction of the novel latch needle warp knitting 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.
