Technical Field

The invention belongs to the technical field of ring spinning frames, and particularly relates to a suspension type active false twisting winding device of a ring spinning frame.

Background

In the field of spinning, although there are new technologies with high yarn forming speed such as vortex spinning and rotor spinning, ring spinning is still the dominant technology for producing spun yarn due to its unique yarn forming style, large strength, wide spinning range and the like. With the development of the textile industry towards automation, intellectualization, high speed and low cost, the output speed of the ring spinning single spindle becomes the most important factor influencing the production efficiency.

Analyzing in principle, the ring spinning technology is invented, and the three processes of drafting, twisting and winding forming are carried out simultaneously to form spun yarns all the time; along with the reduction of scientific and technological development and technical application cost, the improvement of the drafting speed can be realized by increasing the rotating speed of the roller and the diameter of the roller to improve the output speed of the fiber bundle, and the twisting efficiency can be realized by the technologies of a high-speed spindle, a high-speed electric spindle and the like.

However, the winding formation is realized by the passive sliding of the traveller around the ring track under the dragging of the spun yarn, and the structure becomes the bottleneck of ring spinning speed increase under the high-speed spinning environment: with the increase of the ingot speed, the sliding speed of the steel wire ring must be synchronously increased, and the steel wire ring is easy to wear with the ring runway, glue at high temperature, separate from the runway and the like under the influence of comprehensive factors such as spun yarn tension, wind resistance, contact friction, boundary friction and the like. The technical research aiming at winding is not in the rise in the industry, and the rotation speed which can be borne by the steel wire ring can be improved to a certain extent by replacing manufacturing materials, improving the heat treatment technology, coating antifriction materials on the steel wire ring and the steel collar and the like.

The patent ' magnetic suspension ring ', ' ring assembly supported by rollers and capable of driving rotation ' and ' ring assembly supported by spherical roller paths and ' ring capable of driving rotation ' all try to adopt a method of reducing relative speed by relative movement from a mechanical structure, so that the ring and the traveler rotate in the same direction to reduce the relative speed between the ring and the traveler, thereby realizing high-speed winding; however, the structures described in these patents all retain the traveler, and analysis suggests that the relative speed between the traveler and the ring can be reduced, but the speed between the traveler and the spinning frame fixing part is not reduced, so long as the traveler exists and passively slides along the ring track under the traction of the spun yarn, the tension, wind resistance, contact friction and boundary friction of the spun yarn, which are applied to the traveler, are still the determining factors limiting the smooth running of the traveler; if a winding technology with a broken structure cannot be provided, and the research is perfected, the large-scale speed increase of the ring spinning can only be carried out within a limited range.
