Description

Technical Field

[0001] The utility model relates to the technical field of elastic weft yarn production, in particular to cotton dust filtering equipment for a spinning machine producing elastic weft yarn. Background Art

[0002] Elastic weft yarn is a core-spun yarn, which is composed of nylon 66 filament wrapped with cotton fiber. One of the processes in producing elastic weft yarn is nylon filament wrapped with cotton. Spinning frame is used for cotton wrapping. Spinning frame will break in the process of cotton wrapping, and cotton fiber will be produced after breaking. The cotton fiber is sucked into the cotton collecting box at the rear of the machine through the flute-air duct by the centrifugal fan of the spinning frame. There is a layer of filter in the cotton collecting box, which can retain most of the cotton fiber, but some short fibers are blown freely into the workshop by the wind, so that the air in the workshop contains a lot of cotton dust. Therefore, cotton dust filtering equipment is also needed to filter the residual cotton dust.

[0003] In the existing cotton dust filtering equipment for producing elastic weft spinning machines, a large amount of cotton dust will accumulate on the surface of the filter after long-term use. Traditional manual cleaning requires taking it out and shutting down the spinning machine, which reduces production efficiency. Manual regular cleaning of the cotton dust is time-consuming and labor-intensive. Utility Model Content
