[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0036] like Figure 1 As shown, a carbon fiber yarn laying and threading intelligent adjustment rotary reed includes a frame 1, and the frame 1 is provided with:

[0037] Linear reciprocating drive mechanism 2, which can be but not limited to a pneumatic cylinder, an electric cylinder, etc.;

[0038] The yarn splitting reed 3 comprises a reed body 301, wherein the reed body 301 is provided with reed holes 302 for the yarn to pass through;

[0039] The rotary conversion mechanism 4 is disposed between the linear reciprocating drive mechanism 2 and the yarn-dividing reed 3 and is used to convert the linear motion of the linear reciprocating drive mechanism 2 into the rotary motion of the yarn-dividing reed 3, thereby achieving the adjustability of the yarn-dividing reed 3. During operation, the yarn-dividing reed 3 can be rotated forward or backward by controlling the extension or retraction of the linear reciprocating drive mechanism 2, so that it can be adjusted according to the direction of the yarn, allowing the yarn to pass through the center of the reed hole 302 without friction with the wall of the reed hole 302, thereby ensuring yarn strength and increasing the service life of the yarn-dividing reed 3.

[0040] In some examples, such as Figure 2 and Figure 3 As shown, the rotation conversion mechanism 4 includes a push plate 401 hinged to the linear reciprocating drive mechanism 2 and a swing assembly for connecting the push plate 401 and the yarn dividing reed 3;

[0041] The swing assembly includes a central shaft 402 rotatably inserted into the frame 1. One end of the central shaft 402 along its axial direction is connected to the above-mentioned yarn-dividing reed 3, and the other end is connected to a rocker 403. A connecting rod 404 is provided between the rocker 403 and the push plate 401. The central shaft 402 and the connecting rod 404 are all vertical and parallel to each other, and the push plate 401, the rocker 403 and the yarn-dividing reed 3 are all horizontal and parallel to each other.

[0042] When the output shaft of the linear reciprocating drive mechanism 2 extends forward, it drives the push plate 401 to move backward, and the connecting rod 404 moves backward synchronously and drives the rocker rod 403 to rotate in the clockwise direction, and the central shaft 402 and the yarn reed 3 rotate synchronously;

The several connecting rods 404 correspond to the several through holes one by one and the insertion section 4041 of each connecting rod 404 is inserted into the corresponding through hole. Each connecting rod 404 has two corresponding axis clamps 405. The two axis clamps 405 are clamped on the upper and lower limiting sections 4042 and abut against both sides of the push plate 401 to limit the connecting rod 404 and prevent it from detaching from the push plate 401.

The first pin shaft 502 passes through the first support body 501 and the linear reciprocating drive mechanism 2, and shaft stops 503 for axially limiting the shaft are installed at both ends along the axial direction. A slot for installing the shaft stop 503 is opened on the first pin shaft 502.

The second double clevis support 6 includes a second support body 601 and a second pin 602. The second pin 602 passes through the second support body 601 and the push plate 401. The connecting rod 404, the first pin 502 and the second pin 602 are all parallel to each other.

[0048] In some examples, the push plate 401 includes a mounting section 4011 for mounting the swing assembly and a bending section 4012 formed by bending from the end of the mounting section 4011 , and adopts an arc transition. The bending section 4012 is hinged to the linear reciprocating drive mechanism 2 .

[0049] In some examples, the rack 1 includes a fixing plate 101, the middle portion of which is recessed and embedded with a mounting plate 102, the mounting plate 102 including two plate bodies 1021 arranged in parallel, the two plate bodies 1021 enclosing a through hole for the central axis 402 to pass through, the bolts sequentially pass through the two plate bodies 1021 and the fixing plate 101 to fix the three, and the recessed portion of the fixing plate 101 extends downward, thereby increasing its contact area with the mounting plate 102 and improving the connection strength between the two.

[0050] In some examples, such as Figure 1 As shown, the frame 1 is provided with a limiting member 103 for limiting the stroke of the push plate 401 . The limiting member 103 may be, but is not limited to, a bolt.

[0051] In some examples, such as Figure 6 As shown, the reed hole 302 is rectangular, which is adapted to the shape of the carbon fiber, and the upper end surface and the lower end surface of the reed hole 302 are both provided with chamfers to reduce friction between the reed hole 302 and the yarn and avoid damaging the yarn.
