Description

Technical Field

[0001] The invention relates to the technical field of spinning frames, in particular to a spinning frame with a dust removal function. Background Art

[0002] Spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or slivers into spun yarn during the spinning process. The slivers are stretched and twisted on the roving frame to make roving, the combing machine combs the fibers to make combed slivers, the needle combing machine combines the slivers, and the needle row stretching improves the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame.

[0003] In the process of making spun yarn from coarse yarn, the spun yarn passes through the yarn guide hook from the front roller, and then passes through the wire ring on the steel collar and is wound around the empty tube on the spindle. In this process, appropriate tension is conducive to winding the spun yarn, but the friction between the spun yarn and the yarn guide hook and the friction between the steel collar and the wire ring can cause the spun yarn to break. The tapered empty tube at the smaller end can also cause the spun yarn to break. In addition, fluff will be generated where there is friction in the spun yarn, which will increase the friction and affect the working environment.
