[0031] A bracket 1, a roller 11 is arranged at the bottom of the bracket 1, and the bracket 1 can be movably arranged on the ground through the roller 11;

[0032] Two chucks 2, the two chucks 2 are arranged on the bracket 1 and are located at two ends of the bracket 1 in the length direction;

[0033] The air expansion shaft 3 is arranged between the two chucks 2 , the air expansion shaft 3 is arranged horizontally, and the felt is arranged on the air expansion shaft 3 .

[0034] The bottom of the bracket 1 is provided with a roller 11, and the bracket 1 can be moved on the ground through the roller 11. This allows the felt frame to be adjusted according to actual needs to ensure alignment with the position of the warp knitting machine to avoid felt wrinkles and deviations. The felt is set on the air expansion shaft 3, and through the tension control function of the air expansion shaft 3, it is ensured that the felt always maintains appropriate tension during the guided feeding process, reducing wrinkles and deviations, which can effectively solve the wrinkle and deviation problems that occur in the felt guided feeding process of the existing high-speed multi-axial warp knitting machine, and improve production efficiency and product quality.

[0035] In this embodiment, a guide rail 4 is further provided on the ground, and the roller 11 is located in the guide rail 4 , and the guide rail 4 limits the rotational movement of the roller 11 .

[0036] The roller 11 at the bottom of the bracket 1 is located in the guide rail 4 on the ground. The guide rail 4 limits the movement of the roller 11 to ensure that the bracket 1 can only move along the path specified by the guide rail 4, avoiding the problem of position deviation caused by free movement. By setting the guide rail 4 on the ground and limiting the roller 11 of the bracket 1, the design of the felt frame for the high-speed multi-axial warp knitting machine can be further optimized. This improvement not only improves the accuracy and stability of the movement of the bracket 1, but also further reduces the possibility of wrinkles and deviations in the felt guiding process, ensuring a more efficient production process and higher product quality.

[0037] The roller 11 is provided with a brake 111 . When the bracket 1 moves to a position, the position is fixed by the brake 111 , thereby limiting the rotation of the roller 11 .

[0038] The design of the felt frame for the high-speed multi-axial warp knitting machine can be further optimized by providing a brake 111 system on the roller 11. The brake 111 system not only improves the movement accuracy and stability of the bracket 1, but also prevents the bracket 1 from positional deviation during the production process, ensuring a more efficient production process and higher product quality.

[0039] In this embodiment, a tension control component 5 is provided on one of the chucks 2. The tension control component 5 provides a set resistance when the air inflation shaft 3 rotates, so as to control the tension of the felt during unwinding.

[0040] The tension control assembly 5 comprises:

[0041] The tension wheel 51 is arranged on the chuck 2 and rotates synchronously with the air expansion shaft 3;

[0042] The friction assembly 52 at least partially contacts the tension wheel 51 and provides a set resistance when the tension wheel 51 rotates.

[0043] By introducing the tension control component 5 into the design of the felt frame for the high-speed multi-axial warp knitting machine, the wrinkle and deviation problems in the felt guiding process can be effectively solved.

[0045] A belt 521, one end of which is fixedly disposed on the bracket 1 and at least partially wound around the tension wheel 51;

[0046] The tension spring 522 is disposed at the other end of the belt 521 and is fixedly disposed on the bracket 1 .

[0047] By introducing a friction assembly 52 composed of a belt 521 and a tension spring 522 into the design of a felt frame for a high-speed multi-axial warp knitting machine, the wrinkle and offset problems occurring during the felt guiding process can be effectively solved. The tension control assembly 5 provides a set resistance to accurately control the tension of the felt during unwinding, thereby ensuring the stability and accuracy of the felt guiding.

[0048] Among them, the tension spring 522 is fixedly arranged on one end of the bracket 1 and is provided with an adjusting screw 523, the adjusting screw 523 is threadedly connected to the bracket 1, and the adjusting screw 523 adjusts the elastic force of the tension spring 522 when being adjusted.

[0049] The tension wheel 51 rotates synchronously with the air shaft 3, and the belt 521 is partially wound around the tension wheel 51. The tension spring 522 is connected to the other end of the belt 521 and fixed to the bracket 1. The adjusting screw 523 is threadedly connected to the bracket 1, and the elastic force of the tension spring 522 can be adjusted by adjusting the screw 523. When the tension wheel 51 rotates, the belt 521 provides friction, and the tension spring 522 provides additional resistance. The adjusting screw 523 can accurately adjust the elastic force of the tension spring 522 as needed, thereby controlling the rotation resistance of the tension wheel 51, thereby flexibly controlling the tension, adapting to different production requirements, and ensuring the stability and accuracy of the felt guide.

[0050] As a preferred embodiment of the above, the tension wheel 51 is provided with an annular groove 511 along the circumference, and the belt 521 is arranged in the annular groove 511.
