Summary of the invention
The purpose of this invention is to provide the special-purpose drafting system of a kind of half spinning drawing frame, make the pressure drawing-off of drawing frame become the single apron slip draft, thus avoid or reduce overcut fibre in the yarn by tensile phenomenon.The friction field that can change as required in addition in the draw zone distributes, and the floating fiber in the yarn is controlled effectively, and further improves the quality of fiber skein.
The present invention realizes through following technical measures; A kind of single apron slip draft device of drawing frame promptly is provided, and, back roller roller pair secondary by the front leather roller roller formed, and it is characterized in that also comprising medium rubber roller, smooth middle roller, apron and turning cylinder; The position of smooth middle roller yarn process at the middle part has groove; Said apron is enclosed within smooth middle roller and turning cylinder outside, and idler roller tensioning apron is arranged, and apron and smooth middle roller and turning cylinder are fitted tightly; Link to each other by train between smooth middle roller and the turning cylinder, and realize that by idle wheel idler roller and smooth middle roller rotate in the same way.
Said apron is the apron of active drive, and the conveying fiber yarn.
Said apron can swing around smooth middle roller axle center, and is positioned diverse location, with the distribution of adjustment friction field.
Advantage of the present invention is that drawing frame is on-stream; After yarn gets into the middle jaw of medium rubber roller and apron composition; Because the existence of smooth middle roller groove, the overcut fibre in the yarn is controlled and is not gripped at this, thereby avoids or reduced the fracture of overcut fibre.
In addition, traditional smooth groove part is arranged on the roller, and apron all is allokinetic; The situation that the apron motion is made a pause takes place easily, and the present invention is arranged on the below with smooth groove, and adopts the single apron conveying fiber of active drive; The speed loss of fiber in drafting process still less, speed change is more reasonable.
Traditional apron position is all fixed; Apron of the present invention can swing around smooth middle roller axle center and locate; The position is different, and the distribution of friction field is just different, and the present invention can adjust the distribution situation of friction field according to short fibre content; Thereby floating fiber is reasonably controlled, made the fiber speed change even more ideal.
