Multi-axial chain device for warp knitting machine

Abstract

The invention relates a component of a warp knitting machine, in particular to a multi-axial chain device for the warp knitting machine, which comprises a needle board provided with a needle block, at least one chain link and a transverse U-shaped chain box, wherein the chain link is provided with a left lateral plate and a right lateral plate which are connected with the needle board, the upper part of the transverse U-shaped chain box is connected with a limiting block and a sliding rail, one end of the needle board is connected with the needle block while the other end is provided with a 90-degree bend, the vertical surface of the bend is provided with a first rolling shaft on a horizontal axial line, and the first rolling shaft is in rolling fit with the limiting block connected with the upper part of the transverse U-shaped chain box; and the horizontal surface of the bend of the needle board is provided with a second rolling shaft of a vertical axial line, and the upper part of the transverse U-shaped chain box is provided with a chock block which is in rolling fit with the second rolling shaft. The multi-axial chain transmitting device for the warp knitting machine has a simple and compact structure, is convenient to mount, prevents rollover phenomena of chains, runs stably and reliably, and further improves the quality of a surface fabric.

Description

technical field [0001] The invention relates to a part of a warp knitting machine, in particular to a multiaxial warp knitting machine chain device. Background technique [0002] The existing warp knitting machine chain transmission device includes a needle block, a needle plate, at least one chain link and a horizontal U-shaped chain box, and the chain link has left and right side plates connected with the needle plate. The horizontal U-shaped chain box has a limit block and a slide rail, the chain link can roll on the slide rail, and the needle plate is equipped with rollers to roll and cooperate with the limit block. In the chain conveying device of this structure, the function of the limit block is to prevent the chain from turning over during the weaving process, but because the cloth surface must be tightened, especially on a wider cloth surface, the cloth faces the side of the chain. The pulling force is very large, so that the cloth surface will pull the chain towar...

Problems solved by technology

In the chain conveying device of this structure, the function of the limit block is to prevent the chain from turning over during the weaving process, but because the cloth surface must be tightened, especially on a wider cloth surface, the cloth faces the side of the chain. The pulling force is very large, so that the cloth surface will pull the chain towards the middle, and the chain will still roll over, which will directly affect the quality of the cloth surface and form waste products
