Adjustable weft repeated laying device

Abstract

The invention provides an adjustable weft repeated laying device and belongs to the field of glass fiber cloth weaving. The adjustable weft repeated laying device comprises a laying distance adjustingcomponent and a laying component, wherein a first laying wheel and a second laying wheel of the laying distance adjusting component are rotatablely arranged on a fixed laying wheel support; both a third laying wheel and a fourth laying wheel can be rotatablely arranged on a movable laying wheel support; a laying belt is arranged on the first laying wheel, the second laying wheel, the third layingwheel and the fourth laying wheel in a surrounding manner; a laying support for the laying component is mounted on the laying belt; yarn guiding wheels are rotatablely arranged on a yarn guiding wheel fulcrum shaft at equal intervals; laying pull rings are arranged on a laying pull ring rack at equal intervals; a fixing yarn guiding rod is rotatablely arranged on a fixing yarn guiding rod support; the upper end of a swinging yarn guiding rack is hinged to the lower end of the fixing yarn guiding rod support; and swinging yarn guiding rings are mounted on a swinging yarn guiding ring support at equal intervals. According to the adjustable weft repeated laying device provided by the invention, on the premise of not changing the laying belt, broadwise distance adjustment in weft laying can be achieved.

Description

technical field [0001] The invention relates to the field of glass fiber cloth weaving, in particular to an adjustable weft yarn reciprocating laying device. Background technique [0002] Fiberglass grid cloth is a non-twisted roving plain weave fabric, which is an important base material for hand lay-up FRP. The strength of the square cloth is mainly in the warp and weft directions of the fabric. For occasions that require high warp or weft strength, it can also be woven into unidirectional fabrics. It can arrange more untwisted rovings in the warp or weft directions. Warp to fabric, single weft to fabric. The roving is made of bundles of parallel strands or parallel monofilaments. According to the glass composition, the roving can be divided into: E-GLASS non-alkali glass roving and C-GLASS medium alkali glass roving. The quality requirements of the checkered cloth are as follows: ① The fabric is uniform, the selvedge is straight, the cloth surface is flat and mat-like,...

AI Technical Summary

Problems solved by technology

At present, the weft laying length of the common reciprocating laying device is generally not adjustable, but in production, the weft distance of the glass fiber cloth needs to be adjusted, that is, the width requirements are different. The current common reciprocating laying The laying device can only produce a glass fiber cloth with a fixed width. If the production width needs to be changed, only a different type of equipment can be replaced.
