[0028] Embodiment 2:

[0029] On the basis of the first embodiment, the winding mechanism includes an anti-stacking unit and a winding unit. The anti-stacking unit includes a connecting block 1 301, a threaded rod 302, a movable block 303, a limiting ring 304, a connecting block and a motor 1 306. The lower surfaces of the connecting block 1 301 and the connecting block 2 305 are respectively fixedly connected to the front of the upper surface of the support column 1 201 and the support column 2 202, providing a stable installation foundation for the anti-stacking unit.

The right end of the threaded rod 302 penetrates the connecting block 2 305 and extends outward, and cooperates with the movable block 303 to realize the adjustment function to prevent the braided material from accumulating during the winding process. The right end of the threaded rod 302 is connected to the output shaft of the motor 1 306. The movable block 303 is threadedly connected to the threaded rod 302. It is threadedly connected to the threaded rod 302 and can move with the rotation of the threaded rod 302, thereby adjusting the winding position to prevent accumulation on the winding roller 504.

[0031] Working principle: When the braided material needs to be placed on the mold, first place it inside the positioning mold 601, and pass one end of the material through the through hole of the positioning mold 601. Place the roll of material on the clamping ring 603, and the spring 1 602 moves under the action of squeezing to play a buffering role. And the resilient limit clamp 604 is adaptively adjusted to ensure that the braided material is stably fixed on the mold. During the braiding process, due to the action of the clamping ring 603 and the limit clamp 604, the braided material can maintain a stable position and will not shift or fall off.

[0032] At the same time, the motor 1 306 is started to drive the threaded rod 302 to rotate. The movable block 303 moves along the thread direction under the drive of the threaded rod 302. By adjusting the position of the movable block 303, the position of the woven material can be controlled to prevent the material from piling up. The motor 2 501 is started to drive the connecting strip 503 and the roller 504 to rotate. The woven material is evenly wound on the roller 504 to achieve material collection and sorting. The buffer spring frame 506 reduces the vibration and noise generated by the machine during operation and ensures the stability of the roller 504 during the winding process.
