Abstract
The utility model relates to a single-yarn tension control device of a cylinder creel for a carbon-fiber weaving loom; the device is characterized in that: a group of tension wheel assembly is arranged on each yarn cylinder along the obliquely-above direction which is deviated from the loom, a yarn-guiding porcelain eye is arranged in front of a first line-incoming tension wheel in each group of the tension wheel assembly, yarns on each yarn cylinder are led to the loom through the corresponding yarn-guiding porcelain eye and the tension wheel assembly sequentially. In the device, each yarn is adopted to pass through one group of the tension wheel assembly and than is pulled out, the wrap angle of the yarn on each tension wheel is increased, at the same time, as the tension wheel is a soft rubber wheel, the friction force is increased, so as to lead the yarn to not slide on the surface of the tension wheel, reduce the friction of the yarns and obtain larger tension force of the yarn; meanwhile, the device can realize that the single-yarn tension can be adjusted without being affect by the size of the yarn cylinder by adjusting the yarn tension with a spring. In addition, the whole structure is compact, the production space is saved, and the weaving requirements of the carbon-fiber cloth can be met, thereby having larger market demand.
Description
Technical field:
The utility model relates to a kind of carbon cloth and weaves processing equipment, the fine loom of the specifically a kind of carbon single yarn tension control device of bobbin cradle.
Background technology:
Because the output of carbon cloth is generally little, warping not before weaving, but directly go up loom with the bobbin cradle yarn.The carbon fiber yarn can not change the twist in weaving process, so yarn must be used the radially method of unwinding on the bobbin cradle; Simultaneously the carbon fiber yarn does not generally have the twist or the twist very little, reduce friction as far as possible, can't adopt conventional bobbin cradle structure and tensioner, and its single yarn tension control becomes a difficult problem.
During domestic weaving, owing to there is not suitable method, do not control single yarn tension usually, the inequality of warp tension causes the out-of-flatness of cloth cover, is difficult to weave high-quality carbon fiber cloth.Single yarn tension is controlled in the also useful belt damping of domestic high-grade carbon cloth, and this way is actual to be to fixing moment of resistance of yarn tube core, and yarn bobbin tightly is enclosed within on the yarn tube core, and when yarn tube diameter changed, yarn tension also changed thereupon.Usually external diameter is 140mm during the full bobbin of carbon fiber yarn tube, and external diameter is 80mm during empty bobbin, and the tension difference during theoretical overhead full bobbin reaches 140 ÷ 80=1.75 doubly, and tension difference is still very big, can't realize that permanent tension force weaves.To adopt yarn tube core in addition and realize that yarn bobbin tightly is enclosed within the structure on the yarn tube core, complex structure, production cost height.
Automatically regulate single yarn tension with lever principle in the external expensive goods, lever swing when yarn tension changes changes the moment of resistance realization single yarn tension of yarn tube core is regulated automatically.The shortcoming of this method is: 1. this method is passive adjusting, and degree of regulation is not high, and part manufacturing and installation accuracy are very big to the degree of regulation influence, make yarn tension still have certain difference.2. this method is except that adopting yarn tube core and realizing that yarn bobbin tightly is enclosed within the structure on the yarn tube core, and each yarn tube also will have a cover leverage, complex structure, production cost height.3. the shortcoming of this method maximum is to split very greatly apart from (distance between yarn tube and the yarn tube), and bobbin cradle is very long, requires the production space big, simultaneously before and after the also increase to some extent of tension difference of yarn.
The utility model content
The purpose of this utility model is to provide a kind of single yarn tension that can make adjustable, and yarn tension is not subjected to the influence of yarn tube size, makes the single yarn tension control device of the fine loom of a kind of carbon of its requirements of weaving process that can satisfy carbon cloth with bobbin cradle.
For achieving the above object, the technical scheme that the utility model adopted is: this device comprises bobbin cradle, yarn tube, yarn, the bar that splits, back-up ring, it is characterized in that: each yarn tube is provided with one group of straining pulley assembly at the oblique upper of deflection loom, be provided with a yarn poteye before the straining pulley of first inlet wire in every group of straining pulley assembly, yarn poteye is fixed on the porcelain eye plate, and the porcelain eye plate fits on the bobbin cradle; Yarn on each yarn tube after corresponding yarn poteye, is guided loom into earlier again behind the straining pulley assembly.
The fine loom of the described a kind of carbon single yarn tension control device of bobbin cradle, it is characterized in that: every group of straining pulley assembly is made up of 1-4 straining pulley assembly.
The fine loom of the described a kind of carbon single yarn tension control device of bobbin cradle, it is characterized in that: the straining pulley assembly is that the middle part by the tension force wheel shaft fits on the bobbin cradle symmetrically, both ends are made as screw rod after being provided with two steps to the bilateral symmetry of tension force wheel shaft, on monosymmetric first step of tension force wheel shaft, is furnished with friction plate successively, behind friction plate, is furnished with the straining pulley iron core, the endoporus of straining pulley iron core is fixed on the periphery of pair of bearings, after the endoporus of two bearings is fixed on second step of tension force wheel shaft, be furnished with spring base after fitting over the inner ring of collar extension one bearing, be furnished with spring successively at the screw rod end of joining spring base backward pull wheel shaft, pad, nut; Be fixed with straining pulley in straining pulley iron core periphery.
The fine loom of the described a kind of carbon single yarn tension control device of bobbin cradle, it is characterized in that: straining pulley is a rubber wheel, the periphery of straining pulley vertically is " recessed " shape.
The utility model beneficial effect compared with prior art: this device is owing to adopt every one thread through pulling out behind one group of straining pulley assembly after the yarn poteye again again, increased the cornerite of yarn on straining pulley, take turns with soft rubber owing to straining pulley simultaneously, increased frictional force, make yarn not slide on the surface of straining pulley, reduce the friction of yarn, and can obtain bigger yarn tension.This device can be regulated the yarn tension size by spring simultaneously, has realized that single yarn tension is adjustable.This apparatus structure is simple, and is easy to adjust, and can realize higher degree of regulation, and yarn tension is not subjected to the influence of yarn tube size.And this cover mechanism has compact overall structure, has saved the production space.Can satisfy the requirements of weaving process of carbon cloth, very big market demand is arranged.
