Description

Knotting device for bobbin winder

Technical Field

The utility model relates to a textile sector especially relates to a knotting device for cone winder.

Background

The bobbin winder is a special device in the textile industry. The winding is used as the last process of spinning and the first process of weaving, plays a role of a bridge bearing the upper part and the lower part, and therefore plays an important role in the field of spinning. The bobbin winder has the main function that after a plurality of bobbins pass through a certain uniform tension to remove harmful shelter points in partial yarns, the bobbins are wound into bobbins with a certain length and uniform density, and the bobbins which meet the quality requirement are used in the subsequent spinning process.

During the winding process of the bobbin winder, when the yarn clearer finds that the yarn is cut off by a yarn defect or the yarn is broken, two sections of yarns need to be reconnected. The quality of the winding joint is directly related to the efficiency and quality of the post-process, so the strength of the knot must resist the stretching and the reed friction of the loom of the post-process, and the size, the shape, the position and the remained yarn tail of the knot have no adverse effect on the production efficiency of the post-process and the appearance of the fabric as far as possible.

The existing automatic bobbin winder mostly adopts an air twisting mode to splice yarns, namely, the high-speed injection of compressed air is utilized to twist two fibers at the tail of the yarns together in a twisting cavity, the twisted yarns formed by the mode are knotless yarns, and the yarn splicing mode is favorable for improving the quality of cloth cover. However, the yarn splicing has great defects that 1) yarn segments at the splicing part are irregular in yarn and not good in appearance; 2) for some yarns with elasticity, strong flexibility, poor cohesion and smooth yarn surfaces, the phenomena of low splicing strength, slipping of splicing joints and the like often occur in the splicing process, the splicing error rate is high, and the normal operation of spooling is influenced; 3) the tension of the twisted yarn is not good, and the quality of the wound yarn bobbin is affected.
