Embodiment 1

[0021] Such as Figure 1-3 As shown, a rapier chuck for carbon fiber expanded flat yarn weaving includes a movable upper jaw 1, a static lower jaw 2, a rotating shaft 3, a compression spring 4, a control device 5 and a weft yarn 8, wherein the movable upper jaw 1 and the static lower jaw 2 Hinged through the rotating shaft 3, and the movable upper jaw 1 can rotate around the rotating shaft 3, a compression spring 4 is provided between the tail end of the movable upper jaw 1 and the stationary lower jaw 2, and a control device is provided on the upper part of the tail end of the movable upper jaw 1 5. It is used to drive the movable upper jaw 1 to rotate, open the movable upper jaw 1, and introduce the weft yarn 8.

[0022] The static lower jaw 2 is installed on the front end of the rapier 6. When the movable upper jaw 1 and the static lower jaw 2 clamp the weft yarn 8, the distance between the horizontal plane of the clamping center and the center of the rotating shaft in the ...

Abstract

The invention relates to a rapier clamp for weaving carbon fiber expanded flat yarns. The rapier clamp comprises a movable upper jaw (1), a stationary lower jaw (2), a rotary shaft (3), a compressionspring (4), a control device (5) and weft yarns (8) ), wherein the movable upper jaw (1) is hinged to the stationary lower jaw (2) by the rotary shaft (3), the movable upper jaw (1) can be rotated around the rotary shaft (3), the compression spring (4) is arranged between the movable upper jaw (1) and the tail end of the stationary lower jaw (2), the control device (5) is arranged in the upper part of the tail end of the movable upper jaw (1) for driving the movable upper jaw (1) to rotate, opening the movable upper jaw (1) and introducing the weft yarns (8). According to the rapier clamp, theinternal structure of the clamp is simplified, so that the size of the clamp is reduced as much as possible, the size of an opening is reduced, the degree of damage to the carbon fiber is reduced, and the production efficiency of a loom is improved.

Description

technical field [0001] The invention belongs to the technical field of weaving machine parts, in particular to a rapier chuck for weaving carbon fiber bundle expanded flat yarn. Background technique [0002] Low-weight carbon fiber fabric refers to a fabric with high fiber volume content and light weight obtained by weaving flat filaments formed by carbon fiber tows after fiber expansion as warp and weft yarns. This fabric can be used as a reinforcing material and is widely used in aerospace, automobile manufacturing, rail transit, ships and yachts, high-end sports and leisure products and other fields. [0003] At present, only Shijiazhuang Changshan Textile Co., Ltd. has independently developed automatic low-gram carbon fiber weaving equipment in China. Wherein the flat filamentary weft yarn clamping technology is one of the key problems to be solved. [0004] The surface of carbon fiber is smooth, the coefficient of friction is low, and it is not easy to clamp, especial...
