Wool yarn looping device of warp knitting machine with double needle beds

Abstract

The invention discloses a wool yarn looping device of a warp knitting machine with double needle beds. The wool yarn looping device of the warp knitting machine with the double needle beds comprises a guide bar transverse moving mechanism, wherein the guide bar transverse moving mechanism comprises a guide bar, a guide bar hanger, a hanger small shaft, a first supporting seat, a transverse moving stay bar, a steel wire rope and a transverse moving driving device; the guide bar is fixedly arranged on the bottom of the guide bar hanger; and the hanger small shaft is arranged between the guide bar hanger and the first supporting seat. During knitting of the wool yarn looping device of the warp knitting machine with the double needle beds, the transverse moving driving device drives the guide bar to transversely move back and forth along the transverse direction of the warp knitting machine in the left-right direction through the transverse moving stay bar and the steel wire rope. The wool yarn looping device also comprises a supporting tube and a longitudinal moving driving device; the longitudinal moving driving device drives the supporting tube to longitudinally move back and forth along the longitudinal direction of the warp knitting machine in the front-back direction; the guide bar transverse moving mechanism is arranged on the supporting tube; and during knitting of the wool yarn looping device of the warp knitting machine with the double needle beds, the longitudinal moving driving device drives the guide bar to longitudinally move back and forth along the longitudinal direction of the warp knitting machine in the front-back direction through the supporting tube. By the wool yarn looping device, the guide bar transverse moving accuracy and the looping knitting reliability are improved.

Description

technical field [0001] The invention relates to a knitting mechanism of a warp knitting machine, in particular to a wool yarn loop forming device in the knitting mechanism of a double needle bed warp knitting machine. Background technique [0002] The existing double-needle bed warp knitting machine wool yarn loop forming device includes a bar traversing mechanism, and the bar traversing mechanism includes a bar, a bar hanger, a small shaft of the hanger, a support seat, a traversing strut, Steel wire rope and traversing drive device; the bar is fixedly installed on the bottom of the bar hanger, and the small shaft of the hanger is slidably installed between the bar hanger and the support seat, and the bar hanger and the bar The swing arm is fixedly connected, and the bar swing arm is fixedly installed on the bar swing main shaft of the warp knitting machine. The frame of the warp knitting machine is fixedly connected; when weaving, the traversing driving device, such as th...

Problems solved by technology

However, the loop forming device of this structure has the following defects in the following three aspects. On the one hand, with the increase of the opening of the stripping plate, the distance that the bar moves forward and backward also increases accordingly. The increase of the forward and backward movement distance of the bar becomes more and more inclined, which leads to inaccurate lateral movement of the bar, frequent accidents such as missing stitches, and greatly reduces the quality of the fabric; on the other hand, because the bar hanger is installed on the bar On the oscillating main shaft, this increases the load on the bar oscillating main shaft and reduces the reliability of the knitting work; on the other hand, the adjustment range of the off-coil opening gear driven by the cam mechanism is small, and can only be adjusted within the range of 1-100mm
