Weft laying mechanism and weft laying machine comprising same

Abstract

The invention relates to a weft laying mechanism which comprises an external U-shaped frame, an internal U-shaped frame, a needle mounting assembly, a first guide assembly, a first driving part, a second driving part and a third driving part. The external U-shaped frame and the needle mounting assembly synchronously move forwards and backwards under the action of the driving force of the first driving part. The built-in U-shaped frame is placed in a cavity of the external U-shaped frame and performs sliding motion in the left-right direction under the synergistic effect of the first guide assembly, the second driving part and the third driving part, and in the process, the external U-shaped piece and the built-in U-shaped piece cooperate to achieve / release pressing on the fiber cloth strip. The third driving part is composed of a plurality of elastic jacking subunits assembled between the external U-shaped piece and the internal U-shaped piece. In the weft laying process, the second driving part changes the output direction of the pushing and jacking force in a self-adaptive mode according to different actual weft laying positions so as to drive the built-in U-shaped pieces of all the sections in sequence in batches. In addition, the invention also relates to the weft laying machine.

Description

technical field [0001] The invention relates to the technical field of textile machinery and equipment manufacturing, in particular to a weft laying mechanism and a weft laying machine comprising the same. 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 formed by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber. The microcrystalline graphite material obtained by carbonization and graphitization not only has the inherent characteristics 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 u...

AI Technical Summary

Problems solved by technology

It can be seen from the above description that the design structure of the existing left weft laying mechanism is extremely complicated, which is specifically reflected in the need to arrange multiple sets of driving sub-units side by side along the front and rear directions of the weft laying machine. In this way, on the one hand, more investment is required Funds are used to purchase multiple sets of driving sub-units, which in turn leads to an increase in the overall manufacturing cost of the weft laying machine; It will also lead to the extension of the overall installation time of the weft laying machine; on the other hand, it will inevitably greatly increase the design weight of the weft laying mechanism, which is not conducive to the implementation of the weight reduction design goal of the weft laying machine
