AI Technical Summary

Problems solved by technology

In order to establish a larger tension, generally a plurality of long rods are set, and the damage to the yarn is greater
In addition, because it simply rubs against multiple long rods, the control of tension is not accurate, which is not conducive to the winding of fibers

Abstract

The invention discloses a single-wheeled numerical-control coreless yarn roll tension control device and method. Yarn sequentially passes through a tension adjustor, a friction wheel, a spiral leasingcomb, a spiral godet wheel, an outlet godet comb and an outlet godet wheel on the device, one side of the tension adjustor is provided with a plurality of movable guiding columns and fixed guiding columns, the other side of the tension adjustor is provided with a driving structure for driving the movable guiding columns to move relative to the fixed guiding columns, and the movable guiding columns and the fixed guiding columns are configured and arranged at intervals. According to the single-wheeled numerical-control coreless yarn roll tension control device, original tension can be applied to the yarn through the friction wheel, then a tension value of the yarn in the paying-off process is adjusted through mutual cooperation of a magnetic powder brake and the movable guiding columns, theyarn tension stability is maintained, adjusting is more precise, meanwhile, the friction wheel can rotate relative to a spindle to adjust the magnitude of the original tension, and thus applicabilityis good.

Description

technical field [0001] The invention relates to the technical field of composite material winding, in particular to a single-wheel numerical control coreless yarn ball tension control device and method. Background technique [0002] The winding molding process is to wind the continuous fiber (or cloth tape, prepreg yarn) impregnated with resin glue on the mandrel according to certain rules, and then solidify and demould to obtain the product. [0003] The commonly used yarn material for winding is glass fiber, and the glass fiber is in the state of cylindrical or conical yarn balls when it leaves the factory. There are two types of yarn clusters: cored yarn cluster and coreless yarn cluster. The cored yarn cluster has a hollow cylindrical core tube. When winding, the core tube is placed on a fixed core rod, and the yarn is continuously stretched during winding. , during which the yarn cluster rotates around the mandrel, and the tension of the yarn is provided by the frictio...
