Multi-axial carbon fiber yarn zero-degree threading device

Abstract

The invention relates to a multi-axial carbon fiber yarn zero-degree threading device, which comprises a creel and a first guide mechanism at the yarn outlet end of the creel, wherein a first yarn transition support and a second yarn transition support are sequentially arranged at one side of the creel, a second guide mechanism is arranged on the first yarn transition support, a third guide mechanism and a guide plate which is positioned behind the third guide mechanism are arranged on the second yarn transition support, at least a first line of guide holes and a second line of guide holes which is positioned below the first line of guide holes are arranged in the guide plate, both the first and the second lines of guide holes comprise a plurality of guide holes with the same space, and the right end of the first guide hole in the first line of guide holes is vertically intersected with the left end of the guide hole which is in the second line of guide holes and corresponds to the first guide hole; and a jacking device is arranged below the creel, the carbon fiber yarn comes out from the creel to a knitting machine, the device can prevent the surface of the carbon fiber yarn fromgenerating broken filaments, when the carbon fiber yarn enters the knitting machine, no clearance is left between the adjacent carbon fiber yarns, so the knitting quality of a carbon fiber yarn knitting product is improved.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a zero-degree threading device for multiaxial carbon fiber yarns. Background technique [0002] Carbon fiber yarn is a new type of material currently being promoted in the world, which has electrical and thermal conductivity. Carbon fiber yarn products in some advanced countries have been promoted, and domestic enterprises have also put into production carbon fiber yarn, but the quality is still gradually improving. During the weaving process, the carbon fiber yarn needs to be transferred from the creel to the knitting machine through the yarn threading device, but the carbon fiber yarn is easily turned over in the existing yarn threading device, causing friction between the yarn threading device and the carbon fiber yarn Fuzz appears on the surface of the carbon fiber yarn, which affects the quality of the carbon fiber yarn fabric; at the same time, when t...

Problems solved by technology

During the weaving process, the carbon fiber yarn needs to be transferred from the creel to the knitting machine through the yarn threading device, but the carbon fiber yarn is easily turned over in the existing yarn threading device, causing friction between the yarn threading device and the carbon fiber yarn Fuzz appears on the surface of the carbon fiber yarn, which affects the quality of the carbon fiber yarn fabric; at the same time, when the existing threading device transmits the carbon fiber yarn to the weaving machine, there is a certain gap between adjacent carbon fiber yarns, so that after entering the weaving machine, weaving out The product quality is poor; thus the existing yarn threading device seriously affects the quality of carbon fiber yarn products and reduces the competitiveness of carbon fiber yarn products
