Technical Field

The utility model belongs to the technical field of textile equipment, and particularly relates to a multi-guide-bar device for lace and warp knitting and a warp-knitted spacer fabric cloth thereof.

Background

Knitted fabrics are formed by simultaneously knitting one or more sets of parallel aligned yarns on all the working needles of a warp feed machine, a process known as warp knitting and a fabric known as warp knit. The machine that accomplishes this is called a warp knitting machine. The main knitting parts of the warp knitting machine are knitting needles, guide needles, sinkers and press plates. The knitting needles are arranged in a row on the needle bed and move together with the needle bed. The guide needles are mounted on the slats to form guide bars. The warp yarns pass through the eyelets of the guide needles, are fed with the guide bar to be wound around the needles, and are knitted into a fabric by the cooperative movement of knitting members such as knitting needles and sinkers. However, in the actual use process, when the guide bar of the existing warp knitting machine swings, the shogging is inaccurate, and the warp knitting quality is reduced. In addition, the existing guide bar cannot simultaneously carry out pad missing and warp doubling, and cannot meet different warp knitting process requirements.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a warp knitting machine jacquard guide bar [201420358585.X ], which comprises a needle seat and a jacquard guide needle fixed on the needle seat, wherein the rear part of the needle seat extends upwards to form fixing pieces with equal intervals, two adjacent fixing pieces form a fixing groove, the rear part of the jacquard guide needle is clamped in the fixing groove, the front part of the jacquard guide needle is provided with a needle rod, the front end of the needle rod is provided with a guide hole, the front end of the needle seat extends upwards to form a positioning piece with equal intervals, the jacquard guide needle comprises a piezoelectric ceramic section, a needle clamping piece and a needle rod, the needle rod is inserted in the needle clamping piece, the needle clamping piece is fixed with the piezoelectric ceramic section, the distance between the guide hole and the front end of the fixing piece is 73-75mm, and the distance between the guide hole and the front end of the positioning piece is 6-8 mm.

The problem that guide bar shogging location is inaccurate has been solved to a certain extent to above-mentioned scheme, but this scheme still has a lot of insufficiencies, for example the function is single, can't satisfy complicated warp knitting technology demand scheduling problem.
