Abstract
The utility model discloses an elasticity flat -clothing apron strip for carding machine, it includes steel needle and elasticity backer, the operating angle alpha (moving the angle) of steel needle changes ( alpha 1>to the heel is proper to the big -endian from the toe end in the apron strip, alpha n), the operating angle alpha of steel needle is 70 - 78 from the toe end to the proper scope that changes to the big -endian of heel. Through the difference of steel needle operating angle in the apron strip, the apron strip is realized more effectually opening, carded and combing, is favorable to getting rid of impurity, short flannel and cotton knot in the fibre, improves the fibre parallel and stretches straightness to improve the card silver and yarn quality index, also be favorable to reducing elasticity flat -clothing strip and press the production of grinding the burr.
Description
Technical field
The utility model relates to a kind of pin cloth cover plate bar, particularly relates to a kind of textile industry fiber cotton card elastic flat clothing cover plate bar.
Background technology
Cotton card is textile enterprise's spinning critical process equipment, fiber is carried out combing with the acting in conjunction such as Bearded-needle knitted cloth, doff clothing, mixes by elastic flat clothing, remove the impurity in fiber, short suede and cotton knot, the good job of combing, mixing, the short suede of removal impurity and cotton knot effect, directly determines the carded sliver and yarn quality. Well-known same elastic flat clothing to be realized the function of shredding, carded and combing in carding process, plays combing, removes impurity, short suede and cotton knot, makes fiber ultimate fibre turn use into. The realization of these functions depends primarily on flat clothing cover plate bar draw point and plants pin tissue, needling angle size and work angle (dynamic angle) size.
Existing elastic flat clothing cover plate bar draw point is planted pin tissue and is adopted different weave constructions, to adapt to the combing requirement of various fiber, and needling angle and work angle (dynamic angle) is constant from toe end to heel end in same cover plate bar, shown in Fig. 3, elastic flat clothing cover plate bar is made up of draw point 1 ' and elasticity base fabric 2 ', its draw point 1 ' work angle α is constant from toe end to heel end direction size, same work angle, the needs being unfavorable for realizing shredding, carded and combing, thus the carded sliver and yarn quality index is unfavorable. And when needling angle size is certain, work angle is bigger to combing, the removal short suede of impurity and cotton knot influential effect, article one, flat clothing bar draw point work angle size is constant, it is difficult to effectively realize the function of shredding, carded and combing so that the expection requirement that elastic flat clothing carding effect can not reach.
It is thus desirable to provide a kind of new technical scheme solves the problem.
Practical novel content
The technical problems to be solved in the utility model is to provide a kind of cotton card elastic flat clothing cover plate bar. With root cover plate bar draw point work angle from toe end to heel end direction by big to little change, draw point is made to meet the requirement of shredding, carded and combing at carding process, be conducive to flat clothing to remove the impurity in fiber, short suede and cotton knot, make fiber ultimate fibre, thus improve the carded sliver and yarn quality index.
For solving the problems of the technologies described above, cotton card elastic flat clothing cover plate bar of the present utility model, it comprises draw point and elasticity base fabric, the work angle α of described draw point is from toe end to heel end direction by greatly to little change, and the work angle α of described draw point is 70 °-78 ° from toe end to heel end direction by scope to little change greatly.
In the technical scheme of above-mentioned employing, the work angle α of described draw point from toe end to heel end direction by big to little even variation, the difference between operated adjacent angle is (αn-α1)/n, wherein, n is draw point number.
In the technical scheme of above-mentioned employing, the work angle α of described draw point by greatly to subsection change, is divided into 2-4 section from toe end to heel end direction, and the work angle in each segment identifier is identical.
The beneficial effects of the utility model: in cover plate bar the work angle α (dynamic angle) of draw point from toe end to heel end direction by big to little change (α1>αn), by the difference at the work of draw point in cover plate bar angle, cover plate bar realizes more efficiently shredding, carded and combing, be conducive to the impurity removed in fiber, short suede and cotton knot, improve fibers parallel degree of stretching, thus improve the carded sliver and yarn quality index, be also conducive to reducing the generation of elastic flat clothing bar pressure mill burr.

Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
Cotton card elastic flat clothing cover plate bar of the present utility model, it comprises draw point 1 and elasticity base fabric 2, wherein steel wire is cut off bending and forming base fabric punching draw point insertion base fabric hook pulling device draw curved draw point formation work angle α by planting pin machine by draw point 1, and the work angle α of draw point 1 is 70 °-78 ° from toe end to heel end direction by greatly scope to little change.
Embodiment 1:
As shown in Figure 1, the work angle α of draw point 1, planting on pin width from the 76 of toe end ° by greatly to little even variation to heel end 71 °, according to the difference between operated adjacent angle is
(αn-α1)/n, wherein, n is draw point number. Shown in Fig. 1, draw point number elects 38 as, thus obtains, the difference (76 °-71 °)/38 between operated adjacent angle, is decremented to 71 ° of heel end successively from 76 °, toe end by this difference. Work angle is by greatly to little change, big work angle is conducive to shredding, and little work angle is conducive to combing. Therefore, the fiber entering cover plate bar is carried out effective shredding, carded and combing by carding process successively, thus effectively fiber is carried out combing, remove the impurity in fiber, short suede and cotton knot, improve fiber ultimate fibre degree, thus improve the carded sliver and yarn quality index.
Embodiment 2:
As shown in Figure 2, the work angle α of draw point 1 from toe end to heel end direction by changing to subsection greatly, it is divided into 2-4 section, shown in Fig. 2, the work angle α of draw point 1 is changed to little employing 3 sections of subregions by big from toe end to heel end direction, it it is wherein 76 ° at the draw point 1 planting nearly toe end 1/3 on pin width and planting the 1st section of subregion of wide section of the pin angle α that works, the draw point 1 planting pin wide section of the 2nd section of subregion to the heel end 1/3 again angle α that works is 74 °, the draw point 1 that nearly heel end 1/3 plants pin wide section of the 3rd section of subregion angle α that works is 72 °, by the change of 3 segment identifier angles, work angle in each segment identifier is identical, realize the shredding to fiber, carded and combing, thus effectively fiber is carried out combing, remove the impurity in fiber, short suede and cotton knot, improve fiber ultimate fibre degree, thus improve the carded sliver and yarn quality index.
Cotton card elastic flat clothing cover plate bar of the present utility model, with root cover plate bar draw point work angle from toe end to heel end direction by big to little change, draw point is made to meet the requirement of shredding, carded and combing at carding process, flat clothing is conducive to remove the impurity in fiber, short suede and cotton knot, make fiber ultimate fibre, thus improve the carded sliver and yarn quality index.
