Weft yarn cutting mechanism of warp knitting machine

Abstract

The invention discloses a weft yarn cutting mechanism of a warp knitting machine. The weft yarn cutting mechanism comprises a weft yarn cutting box, four connecting posts, an anti-slip bottom foot, afeeding pipe, a control panel, a control box, a display screen and an indicating lamp, wherein the four connecting posts are arranged at the lower surface of the weft yarn cutting box. The weft yarn cutting mechanism of the warp knitting machine has the advantages that the weft yarn cutting box consists of a collecting device, an assistance cutting mechanism, a tension regulating device, a coolingdevice, a starting device, a rotating mechanism and a traction device; the weft yarns can be effectively and flatly dragged and pulled into a conveying guide rail for cutting during the weft yarn guiding; the effect of improving the weft yarn quality is achieved; meanwhile, before the weft yarn cutting, the weft yarn can be abutted to the set cutting position; the tension requirement of the weftyarn can be met; the cutting treatment can be performed, so that the weft yarns maintain certain tension; the winding generated by the weft yarns in the fast yarn conveying an cutting process due to looseness can be prevented.

Description

technical field [0001] The invention relates to a weft yarn cutting mechanism of a warp knitting machine, which belongs to the field of warp knitting machines. Background technique [0002] Use one or several groups of yarns arranged in parallel to form a knitted fabric at the same time on all the working needles of the warp feeding machine. This method is called warp knitting, and the fabric is called warp knitted fabric. The warp knitting machine is called a warp knitting machine. The main loop forming parts of the warp knitting machine are knitting needles, yarn guide needles, sinkers and pressure plates. Installed on the slats to form a bar, the warp yarn passes through the eyelet of the guide needle, moves with the bar and wraps around the needle, and is woven into a fabric through the mutual cooperation of knitting needles, sinkers and other loop-forming components. At present, the common cutting device adopts the method of directly passing the weft yarn to the cuttin...

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a weft yarn cutting mechanism of a warp knitting machine to solve the problem that the cutting device adopts the method of directly transferring the weft yarn to the cutting knife for cutting. In this way, the weft yarn on one side When cutting, the weft yarns will be twisted due to the different tension of the weft yarns on both sides, which will affect the cutting effect. At the same time, due to the insufficient traction force and the light and thin weft yarns during the weft yarn transfer process, the weft yarns are easy to pile up before cutting, making it difficult for the mechanism to its flat cutting problem
