Zero-degree wrap yarn let-off device of multi-axial warp knitting machine

Abstract

The invention provides a zero-degree wrap yarn let-off device of a multi-axial warp knitting machine, comprising a pan head bracket, a yarn compression roller, a separating device and a heating transferring roll device; the separating device comprises a bracket, a synchronizing shaft frame, a supporting plate and a pressing roll; at least two beams are fixed on the bracket, the synchronizing shaft frame, the pan head bracket and the supporting plate are sequentially connected on the beam, a synchronizing shaft connected with a synchronizing wheel is arranged on the synchronizing shaft frame, a paper tube is fixed on the synchronizing shaft, and each paper tube corresponds to the pan head bracket connected on the beam one by one. The heating transferring roll device comprises two pressing rolls, a heating roll and a bracket plate, the bracket plate is provided with a shaft hole for arranging a bearing and a clamp spring, the two ends of the pressing roll are respectively arranged in the bearings of the shaft holes of the two bracket plate, and the heating roll is arranged between the two pressing rolls. The device can lead zero-degree wrap yarn with expanding characteristics such as carbon fiber to be neater and brighter before entering into a head of the warp knitting machine for weaving, so as to greatly improve the cloth quality of textiles.

Description

technical field [0001] The invention relates to the technical field of textile equipment auxiliary devices, in particular to a 0° warp let-off device used on a multiaxial warp knitting machine. Background technique [0002] Generally used for the 0° warp of fabrics, as long as the pan head with yarn raw materials is placed on the pan head frame of the creel, the warp yarn can be pulled out to weave, but for high temperature resistant, friction resistant, conductive and thermally conductive carbon fiber Raw materials, especially due to the expansibility of carbon fiber raw materials, using the 0° warp yarn let-off device on a general multi-axial warp knitting machine will cause problems such as wrinkles, unevenness, and uneven laying, which cannot meet the requirements of weaving. The fabric has a certain thickness, strength and durability, so we can only work hard on the number of layers of weft laying. Therefore, for fabrics made of carbon fiber weft materials, due to the d...

Problems solved by technology

[0002] Generally used for the 0° warp of fabrics, as long as the pan head with yarn raw materials is placed on the pan head frame of the creel, the warp yarn can be pulled out to weave, but for high temperature resistant, friction resistant, conductive and thermally conductive carbon fiber Raw materials, especially due to the expansibility of carbon fiber raw materials, using the 0° warp yarn let-off device installed on a general multi-axial warp knitting machine will cause problems such as wrinkles, unevenness, and uneven laying, which cannot meet the requirements of weaving. The fabric has a certain thickness, strength and durability, and can only work hard on the number of layers of weft laying. Therefore, for fabrics made of carbon fiber weft raw materials, due to the difficulty in technology, generally no 0° warp let-off device is installed, and laying It is also impossible to increase the number of weft layers a lot. Therefore, the current carbon fiber raw material fabrics are relatively thin, and it is difficult to meet the needs of the market.
