Traversing type tightening device

Abstract

The invention relates to a part of a cotton-wool weaving machine, in particular to a traversing tighter of a spinning machine which is formed by a tighter with a fiber channel in the shape of a Chinese character 'Ba' in the longitudinal direction which is arranged on a slide stick by a tighter mounting hole; the tighter is penetrated on the slide stick; the slide stick is parallel with a front roller; the tighter is closely stuck on the surface of the front roller in a floating area at the back surface of a front nip; or the tighter is closely stuck on the surface of the front roller in a twist triangular space in front of the front nip; the tighter can move transversely; a clearance is arranged between the tighter and a front glue roller; the fiber channel of the tighter is provided withtwo smooth side arc surfaces in the shape of the Chinese character 'Ba' with a large inlet and a small outlet; an extruded arc corner is arranged at the location of the inlet of the fiber channel along the transverse direction; the arc corner plays the role of a fiber pressure stick to lead all the traction fiber strands to become tight after passing through the fiber channel of the tighter; after the fiber strands are twisted into yarns, the quality levels of filoplume, mightiness, evenness, rough slub, thin slub and neps for spinning are remarkably improved.

technical field [0001] The invention relates to a cotton and wool textile machine part, which is a traverse compacting device suitable for a spinning machine. Background technique [0002] At present, the distance of the floating area of ​​the fine (coarse) yarn frame is too long, so that the position of the short fibers in the drafting sliver cannot be controlled in the floating area. During drafting, these short fibers are squeezed by the surrounding fast and slow fibers, Uncertain factors such as friction cause early or delayed speed change, which seriously deteriorates the indicators of spun yarn evenness, thickness, and detail. The widened strands in the uncontrolled floating area have too much hairiness after being twisted into yarn, and the strength is low.

[0002] At present, the distance of the floating area of ​​the fine (coarse) yarn frame is too long, so that the position of the short fibers in the drafting sliver cannot be controlled in the floating area. During drafting, these short fibers are squeezed by the surrounding fast and slow fibers, Uncertain factors such as friction cause early or delayed speed change, which seriously deteriorates the indicators such as spun yarn evenness, thickness, and detail

The widened strands in the uncontrolled floating area have too much hairiness after being twisted into yarn, and the strength is low. The compactor part of the prior art "spun yarn collector" only has the function of gathering fibers horizontally, because the fibers are gathered on both sides The curved surface design is unscientific, and only a small amount of hairiness can be reduced. Because of its light weight, it is easy to shake and jump during production, which makes the evenness, thickness, and details significantly worse. The structure of the prior art spun compact spinning device is complicated, and the spinning speed is unacceptable. Cost, high purchase price, and long payback period make the textile industry unable to popularize and use, and affect the comprehensive improvement of cotton yarn quality in the textile industry
