Fiber cloth strip feeding system suitable for weft laying machine

Abstract

The invention relates to a fiber cloth strip feeding system suitable for a weft laying machine. The fiber cloth strip feeding system comprises an unwinding device and a tensioning device. A fiber cloth strip is flattened and sent out through the unwinding device and then sequentially passes through the rotating roller assembly, the gravity roller assembly and the guide roller assembly in a winding mode. In the feeding process of a fiber cloth strip, the rotating roller assembly, the gravity roller assembly and the guide roller assembly always perform circumferential rotating motion around the central axis of the fiber cloth strip under the action of the friction force of the fiber cloth strip, and the gravity roller assembly tensions the fiber cloth strip under the action of the gravity of the gravity roller assembly. Therefore, the fiber cloth strip is always kept in a reasonable tensioning state, the fiber cloth strip can be continuously and stably fed into the weft laying machine, and the weft laying process can be smoothly implemented. In addition, the deflection angle of the gravity roller assembly can also be adaptively changed along with the change of the feeding speed of the fiber cloth strip, so that the phenomenon that the gravity roller assembly is snapped due to the action of overlarge tension is avoided.

Description

technical field [0001] The invention relates to the technical field of textile machinery and equipment manufacturing, in particular to a fiber cloth strip feeding system suitable for a weft laying machine. Background technique [0002] Carbon fiber is a new type of material with a carbon content of more than 95%, with high strength and high modulus. Carbon fiber is composed of organic fibers such as flake graphite microcrystals stacked along the fiber axial direction. The microcrystalline graphite material obtained by carbonization and graphitization not only has the inherent intrinsic properties of carbon materials, but also has the softness of textile fibers. machinability. [0003] The fiber cloth is woven from carbon fiber, and its production process is roughly as follows: flatten the carbon fiber bundle into a flat monofilament carbon fiber through a yarn spreader, and then bond it into a fiber cloth strip with glue, and then spread it by laying The weft machine is us...

Problems solved by technology

Through the application of the above technical solutions, although it can effectively ensure that the yarn in the feeding process is always kept in a reasonable tension state, when the tension of the yarn needs to be adjusted, it is necessary to frequently rotate the screw to increase the tension. Raising or lowering the relative height position of the tensioning wheel is extremely inconvenient for application and operation, and the rotation and operation of the screw completely depends on the experience of the workers, which requires high quality of workers and work responsibility, which is not conducive to popularization and promotion
