A main shaft 3 is mounted on the frame 1, and the motor 2 drives the main shaft 3 to rotate. The main shaft 3 has several sprockets 4, which are cylindrical gears. Several aluminum beams 5 are mounted on the sprockets 4, and are horizontal in direction. Each aluminum beam 5 has a groove 11, and several guide wheels 12 are movably connected within the grooves 11. Each aluminum beam 5 has a clamping plate 6 and a nut 7, which are fixedly connected. A screw 8 is threaded onto each nut 7. Rod 8 moves through the flower plate 4. Several aluminum beams 5 are equipped with several limiting components 9. The limiting components 9 include limiting block 1 901, limiting block 2 902, and screw 2 903. Screw 2 903 is threaded through limiting block 1 901 and flower plate 4 and threadedly connected to limiting block 2 902. Several handles 10 are provided on the main shaft 3. A core mold rotation sensor 14 is provided on the frame 1. The core mold rotation sensor 14 is located on one side of the main shaft 3. A pusher 13 is provided at one end of the main shaft 3. The motor 2, pusher 13, and core mold rotation sensor 14 are all electrically connected to the PLC controller.

[0019] The implementation method of this embodiment is as follows:

[0020] When winding the fiber material, first pull the handle 10 to open the main shaft 3. Simultaneously, the flower disc 4 and aluminum beam 5 are also pulled outwards. Once the specified diameter is reached, use the limiting component 9 to limit the flower disc 4 and aluminum beam 5. Insert the second screw 903 through the limiting block 901 on the aluminum beam 5 and the flower disc 4 on the main shaft 3, and thread it onto the limiting block 902 to ensure a firm contact between the flower disc 4 and the aluminum beam 5.

To begin the winding process, one end of the fiber material is first fixed to the main shaft 3. The motor 2 is started by the PLC controller to drive the main shaft 3 to rotate. At this time, the main shaft 3 drives the fiber material to wind. The core mold rotation sensor 14 monitors the rotation speed and number of turns of the main shaft 3 in real time. For each turn of the fiber material, the pusher 13 pushes once, causing the wound fiber material to slide forward through the guide wheel 12. This winding process is repeated until the fiber material is wound into shape. Finally, the formed fiber winding layer is removed and moved to the fiber winding layer collection point.
