Warp let-off device of double rib warp loom

Abstract

The invention discloses a loom let off device of a double neilsbed tricot machine which includes a plurality of pan head supporting seats fixed connected with transverse two sides of the double neilsbed tricot machine body, a plurality of warp beams connected with the pan head supporting seat and parallel each other, a yarn tension adjusting mechanism fixed connected with the machine body and a yarn ring mechanism, a plurality of pan heads are sleeved on the warp beam, a yarn dividing and guiding mechanism is set on corresponding each pan head respectively that fixed connects with the machine body and is composed of a yarn guiding roll seat set on transverse two sides of the machine body, at least one yarn guiding roll among the yarn guiding roll seats and at least one group yarn dividing needle composed of some yarn dividing needle fixed set on upper part or down part of the yarn guiding roll along the axis line direction. The double neilsbed tricot machine not only acts on tension action to yarn output from the pan head, but also easily finds yarn rupture and connects once more when partly yarn rupture, accordingly, the fabric quality can be ensured, productive efficiency is increased and the machine has better commercial prospect.

Description

technical field [0001] The invention relates to a double-needle-bed warp knitting machine, in particular to a let-off device for a double-needle-bed warp-knitting machine which conveys yarn from a pan head into a yarn knitting mechanism. Background technique [0002] The existing warp let-off device for a double-needle bed warp knitting machine includes a plurality of pan head support seats fixedly connected to the lateral sides of the double needle bed warp knitting machine body, and the pan head set on the lateral sides. A plurality of warp beams, a yarn tension adjustment mechanism, a roller located between the pan head and the yarn tension adjustment mechanism, and a yarn knitting mechanism located at the lower part of the yarn tension adjustment mechanism are rotatably connected to the support base and arranged parallel to each other. The pan head is sleeved on the warp beam, and the yarn tension adjustment mechanism includes a guide roller seat and a guide roller, a ya...

AI Technical Summary

Problems solved by technology

Such a let-off device, because the roller only acts as a tension force on the yarn output from the pan head, and when a part of the yarn passing through the roller breaks, it is difficult to find it from the roller on the one hand, thus affecting the quality of the fabric. On the one hand, even if found, it is extremely difficult to find these broken yarns from the huge number of yarns, requiring downtime and often taking hours to find, thus greatly reducing production efficiency
