Embodiment 1
[0018] Such as figure 1 and figure 2 Shown, a kind of rapier collet used for weaving of carbon fiber expanded flat yarn comprises fixed lower collet 1, movable upper collet 2, rotating shaft 3, spring 4, control device 5 and weft yarn 7, wherein said fixed lower collet The upper end of 1 is provided with an inclined support rod 8, which is used to connect with the movable upper chuck 2. The movable upper chuck 2 includes a movable arm 2-1 and a follower arm 2-2. The movable arm 2-1 is connected with the follower arm The angle of the movable arm 2-2 is 90°-135°, and it is fixedly connected. The connection between the movable arm 2-1 and the follower arm 2-2 is connected with the support rod 8 through the rotating shaft 3, and the movable arm 2-1 can be With the follower arm 2-2 rotating around the rotation axis 3, the vertical distance from the center of the rotation axis 3 to the clamping surface of the fixed lower chuck 1 is less than the length L of the follower arm 2-2, w...

The invention relates to a rapier clamping head for carbon fiber expanded flat filament weaving. The rapier clamping head comprises a lower fixing clamping head, an upper movable clamping head, a rotary shaft, springs, a control device and weft yarn, wherein the upper end of the lower fixing clamping head is provided with an oblique support rod for being connected with the upper movable clamping head. The upper movable clamping head comprises a movable arm and a servo arm which are fixedly connected in a certain angle. The joint between the movable arm and the servo arm is connected with the support rod through the rotary shaft. Besides, the movable arm can drive the servo arm to rotate around the rotary shaft. The vertical distance between the center of the rotary shaft and the clamping surface of the lower fixing clamping head is smaller than the length L of the servo arm. The rotary shaft is used for effectively clamping the yarn when the upper movable clamping head rotates. Clamping grooves corresponding to the springs are formed in the servo arm and the support rod respectively. According to the rapier clamping head for carbon fiber expanded flat filament weaving, the internalstructure of the clamping head is simplified, hence, the size of the clamping head can be reduced as much as possible, the size of an opening is reduced, damage to carbon fibers is reduced, and the production efficiency of a weaving machine is increased.
Description
technical field [0001] The invention belongs to the technical field of textile machinery parts, in particular to a rapier chuck for weaving carbon fiber 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 fully automatic low-gram carbon fiber weaving equipment in China. Wherein the flat filamentary weft yarn clamping technology is exactly one of the key problems that need to be solved. [0004] The surface of carbon fiber is smooth, the coefficient of friction is low, and it is not easy...
