[0043] The working principle of the present application is that:

[0044] The thread lifting bar frames 15 are all in the initial position and keep the same height, during the working process, the movement mode of the thread lifting bar frames 15 is set to be partially moved up and partially returned to the initial position, in the above embodiment, the movement mode is set to be that the interval thread lifting bar frames 15 are simultaneously moved up or returned to the initial position, that is, from the front side of the housing, the odd-numbered thread lifting bar frames 15 are group A, the even-numbered thread lifting bar frames 15 are group B, and group A and group B are alternately raised and lowered, in this process, the optical fibers originally on the same plane are divided into two layers, and an optical fiber is placed between the two layers, and one weaving is completed by the presser bar 8, then the thread lifting bar frames 15 originally moved up are moved down to reset, and the thread lifting bar frames 15 originally in the initial position are moved up, that is, the thread lifting bar frames 15 are alternately moved up and down, at this time, the optical fibers are again divided into two layers, the optical fibers originally in the upper layer are in the lower layer, and the optical fibers originally in the lower layer are in the upper layer, and an optical fiber is again placed between the two layers, and one weaving is again completed by the presser bar 8, and the above operation is repeated to complete the weaving of the optical fiber fabric;

[0045] During the weaving process, the presser bar 8 gives different pressure and pressure holding time in each weaving, so that the optical fibers have different bending angles and the optical fibers in the same fabric have different density arrangement, so that the refracted light energy is consistent, and the whole fabric forms a uniform sheet-shaped light source.

[0046] During the whole working process, the warp beam 13 is controlled by the motor to make the optical fiber wound on the warp beam 13 transported to the structure forming and weaving mechanism according to a constant step, and the fabric collecting shaft 6 is controlled by another motor to rotate at a speed, so as to ensure that the axial tension of the optical fiber is consistent. Since the optical fiber wound on the warp beam 13 gradually decreases in diameter during the working process, and the optical fiber fabric wound on the fabric collecting shaft 6 becomes more and the diameter becomes larger, the speed is automatically adjusted by the controller B5 to avoid the situation that the optical fiber is pulled off or relaxed.
