[0043] The reed angle adjustment device includes a reed connecting seat 41, an angle adjusting member, and a rotating rod 42. Preferably, there are two reed connecting seats 41, two angle adjusting members, and two rotating rods 42, which are arranged in one-to-one correspondence.

At both ends of each reed connecting seat 41, there are lugs 411 clamped on the ends of the reed 1, and the lugs 411 are fixed to the reed 1 by pins, thereby fixing the reed connecting seat 41 to the reed 1.

[0044] Each rotating rod 42 is in an L shape. One of the struts of each rotating rod 42 is fixedly connected to the reed connecting seat 41, and the other strut of each rotating rod 42 is rotatably connected to the corresponding end of the reed fixing frame 21. That is, each reed connecting seat 41 is connected to the reed fixing frame 21 through the corresponding rotating rod 42, enabling the reed 1 to rotate around the reed fixing frame 21.

[0045] There is also an angle adjusting member connected between the reed 1 and the reed fixing frame 21. The angle adjusting member includes a first angle adjusting ring 43 and a second angle adjusting ring 44 distributed inside and outside. The first angle adjusting ring 43 and the second angle adjusting ring 44 are respectively sleeved on the strut where the rotating rod 42 is rotatably connected to the reed fixing frame 21 and fixed to the reed fixing frame 21. The first angle adjusting ring 43 and the second angle adjusting ring 44 extend along the rotation direction of the rotating rod 42, and angle scale values are respectively set on the first angle adjusting ring 43 and the second angle adjusting ring 44.

The output shaft of each drive motor 6 is in transmission connection with the roller 231 of the corresponding support leg 23 through a gear transmission belt 61. By controlling the drive motor 6, the entire reed support frame 22 is driven to move back and forth along the slide rail 3, improving the automation degree of the device.

[0050] Furthermore, the 2.5D woven fabric beating-up device further includes a reed guiding device. The reed guiding device includes a front guide rail frame 71 distributed on the front side of the reed fixing frame 21, a rear guide rail frame 72 distributed on the rear side of the reed fixing frame 21, and at least one guide rail 73 fixed between the front guide rail frame 71 and the rear guide rail frame 72. In this embodiment, there are two guide rails 73, and they are arranged parallel to the slide rail 3. The bottom of the reed fixing frame 21 is provided with guide blocks 211 sleeved on each guide rail 73. There are two guide blocks 211 on each guide rail 73. Through the cooperation of the guide blocks 211 and the guide rails 73, the stability of the movement of the reed fixing frame 21 can be ensured.

[0051] Furthermore, front guide rail feet 711 are respectively arranged at both ends of the front guide rail frame 71, and rear guide rail feet are respectively arranged at both ends of the rear guide rail frame 72. Brake-equipped guide rail rollers 74 are installed on each front guide rail foot 711 and each rear guide rail foot.

Each first angle adjusting arc-shaped member 81 is respectively arranged on the upper side of one end of the reed fixing frame 21, and each second angle arc-shaped member 82 is respectively arranged on the lower side of the corresponding end of the reed fixing frame 21. And the planes where the first angle adjusting arc-shaped member 81 and the second angle adjusting arc-shaped member 82 are located are respectively perpendicular to the plane where the reed fixing frame 21 is located.

And the socket head 83 close to the reed 1 is fixedly connected to the reed 1.

[0056] On the two opposite arc-shaped side walls of the second angle adjusting arc-shaped member 82, there are second angle adjusting grooves. In these two second angle adjusting grooves, there is a second fastener. The second fastener includes two socket heads and a pin passing through between the two socket heads. Each socket head is respectively fixed on the two opposite arc-shaped side walls of the second angle adjusting arc-shaped member 82. The pin passes through between the socket heads from the second angle adjusting groove, and both ends of the pin are fixed to the socket heads through fastening nuts, and the socket head close to the reed is fixedly connected to the reed. The structure of the second angle adjusting arc-shaped member 82 is similar to the structure of the first angle adjusting arc-shaped member 81.

[0057] At the position corresponding to the first angle adjusting groove 811 of the first angle adjusting arc-shaped member 81, there is an angle scale value, and at the position corresponding to the second angle adjusting groove of the second angle adjusting arc-shaped member 82, there is also an angle scale value.

[0058] By adjusting the fastening nuts 85 of the first angle adjusting arc-shaped member 81, the movement of each socket head 83 in the two first angle adjusting grooves 811 can be adjusted. By adjusting the fastening nuts of the second angle adjusting arc-shaped member 82, the movement of each socket head in the two second angle adjusting grooves can be adjusted, so that the rotation angle of the reed 1 can be adjusted. By tightening the fastening nuts 85, an inclined connection can be maintained between the reed 1 and the reed fixing frame 21.

[0059] After adopting the above structure, in a beating-up device for 2.5D woven fabric of the present utility model, by setting a reed angle adjusting device, the angle adjustment and fixation between the reed 1 and the reed fixing frame 21 are realized.
