Description

Double-guide-wheel yarn twisting device

Technical Field

The utility model relates to a yarn twisting device in a direct twisting machine, in particular to a double-guide wheel type yarn twisting device in a direct twisting machine.

Background

In the industrial cloth industry, two or three strands of double twisting wires are needed according to the technological requirements and physical indexes of the fabric, and the traditional manufacturing method is as follows: firstly, twisting industrial precursor (monofilament) by using a ring spindle machine or a two-for-one twister, then feeding the twisted monofilament into the ring spindle twisting machine together in a mode of combining two strands or three strands for re-twisting (the twisting direction is opposite to that of the primary twisting), and finally obtaining the two-strand or three-strand finished yarn through winding and forming. The main disadvantages of the two-step manufacturing process based on the traditional ring twisting machine are that: the production efficiency is low, and the defects of oil stain wire, small package capacity, frequent doffing, large labor consumption, large waste of bobbin yarn tails, low finished fabric production rate and the like are easily generated when the machine-woven fabric is put on the machine-woven fabric. Along with the increasing trend of modern industrial production towards large package precursors and large-capacity wire making, in order to realize the high-speed operation of the weaving process, a one-step direct twisting technology based on a double-guide-wheel wire twisting device (double-guide-wheel wire twisting device) of a direct twisting mode is generally adopted at present and is used for producing two-strand or three-strand yarns, and the working principle is as follows: the large package precursor is put into an spindle yarn tank to be used as an inner yarn, and is led out after passing through an inner yarn tensioner; the outer yarn is put on a creel, enters an electric spindle twisting disc through an outer yarn tensioner and is then led upwards, the inner yarn and the outer yarn are led into a double-guide wheel type yarn twisting device of a direct twisting machine for twisting and shaping, and then enters a roller yarn conveying device for winding through a winding tube to form finished yarn. The traditional double-guide-wheel yarn twisting device is placed on the spindle yarn tank, so that the spindle yarn tank is often damaged in the actual use process, and the service life of the yarn drum is greatly shortened; in addition, because the double guide wheels in the traditional double guide wheel yarn twisting device are horizontally arranged, the double guide wheel yarn twisting device has larger volume and brings inconvenience to installation.
