Carbon fiber cloth loom

Abstract

The invention relates to a carbon fiber cloth loom, comprising a frame, a shedding mechanism, a let-off mechanism, a weft insertion mechanism, a weft-yarn shut-off mechanism, and a take-up mechanism. The carbon fiber cloth loom is characterized in that the loom also comprises an automatic weft releasing and feeding mechanism composed of a sliding plate, a driving structure, a bracket, a set of guide rolls and an air claw; the weft insertion mechanism is composed of a first servo motor, a gear reducer, an arrow wheel and a rigid arrow shaft; the let-off mechanism is composed of a second servo motor, a let-off shaft, a guide shaft and a detection tension shaft; and the take-up mechanism is composed of a rewind shaft and a third servo motor. Each motion part of the loom provided by the invention is driven by an independent power source, and is controlled by a PLC (programmable logic controller) in a centralized way, so that the structure is simplified, and the operating control is convenient; the automatic weft releasing and feeding mechanism ensures that a weft yarn plate is in a specific spatial position before weft insertion, and guarantees the success of each weft insertion; the weft insertion mechanism ensures the weft yarn plate not to wear a warp yarn plate when the weft yarn plate passes through from a shed; and the weft yarn plate introduced to the shed is pushed to a cloth fell by the backward motions of the second servo motor and the third servo motor, so that the requirement for weaving large-width carbon fiber sheet is met.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a carbon fiber cloth loom. Background technique [0002] Carbon fiber cloth is a reinforced material woven from carbon fiber sheets. This material has the characteristics of high strength, light weight, corrosion resistance and durability. It is widely used in aerospace, sports equipment, industry, fire protection and other fields. . For weaving carbon fiber cloth with small-width carbon fiber sheets as warp and weft yarns, such as 12K carbon fiber bundles with a width of 5mm, ordinary looms can be slightly modified to weave conventional carbon fiber cloth. However, for weaving carbon fiber cloth with large-width carbon fiber sheets as warp and weft yarns, such as thinning 12K carbon fiber bundles to form 20mm carbon fiber sheets, the weaving of carbon fiber cloth cannot be realized after a slight improvement of the ordinary loom. The main reason why existing looms ca...

Problems solved by technology

[0005] 3) The wear resistance of carbon fiber materials is poor, and the weft insertion device can only use a rigid arrow shaft weft insertion mechanism, but the traditional rigid arrow shaft weft insertion mechanism generally adopts an eccentric link type or a conjugate cam type structure, which is more complicated. Inconvenient control and low weft insertion reliability

[0006] 4) Existing looms are designed and developed for the thin weft yarn, so the cutter for cutting the weft yarn is very simple, similar to the principle of household scissors, but the carbon fiber sheet is a weft yarn material with a certain width. After the weft insertion action is completed, Only one action cannot cut the weft yarn in the entire width range, it must be composed of several actions to form a complete cutting process, therefore, the traditional scissors cannot meet the cutting requirements of the weft yarn piece
