[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] like Figure 3As shown, this is the state after the winding is completed and before the wire winding begins. The valve plate E5 controls the wire hook pressing cylinder 10 to push the wire hook pressing block 11 downward to press the fiber wire 24 to the wire hook head 17. At this time, the fiber wire 24 is pressed by the wire hook pressing block 11 and the wire hook head 17 and will not slide or fall off.

[0048] like Figure 4 The figure shows the state of winding and cutting. Figure 1-2 The entire wire cutting process is as follows: when the winding is completed and the fiber filament 24 is below the wire hook head 17:

[0049] In the first step, the valve plate B2 controls the slitting and pressing cylinder 13 to drive the slitting and pressing one-way wheel 14 to press the fiber filaments 24 downward;

[0050] In the second step, the valve plate D4 controls the thread hook swing arm cylinder 21 to pull the thread hook swing arm connecting rod 18 to extend and drive the thread hook head 17 to extend outward;

[0051] In the third step, the valve plate C3 controls the wire hook driving cylinder 23 to drive the wire hook driving rod 20 to retract, so that the wire hook driving rotating disk 19 rotates clockwise, driving the wire hook swing arm cylinder 21, the wire hook swing arm connecting rod 18, and the wire hook head 17 to move downward as a whole;

[0052] In the fourth step, the valve plate D4 controls the hook arm cylinder 21 to pull the hook arm connecting rod 18 to retract and drive the hook head 17 to retract inward. At this time, the fiber 24 is above the hook head 17.

[0053] In the fifth step, the valve plate C3 controls the wire hook driving cylinder 23 to drive the wire hook driving rod 20 to extend so that the wire hook driving rotating disk 19 rotates counterclockwise to drive the wire hook swing arm cylinder 21, the wire hook swing arm connecting rod 18, and the wire hook head 17 to move upward as a whole to hook up the fiber filament 24;

[0054] In the sixth step, the valve plate E5 controls the wire-hooking pressing cylinder 10 to push the wire-hooking pressing block 11 downward to press the fiber filament 24 to the wire-hooking head 17. At this time, the fiber filament 24 is pressed by the wire-hooking pressing block 11 and the wire-hooking head 17 and will not slide or fall off.

[0055] Step 7: Valve plate F6 controls the cutter cylinder 12 to push the cutter 15 downward to cut the fiber filament 24. After the fiber filament 24 is cut;

[0056] In the eighth step, the core mold 25 starts to rotate clockwise, and the excess fiber filaments 24 after cutting are pressed onto the surface of the core mold 25 when passing through the cutting and pressing one-way wheel 14;

[0057] In the ninth step, valve plate F6 controls the cutter cylinder 12 to drive the cutter 15 to retract upwards. At the same time, valve plate B2 controls the wire cutting and pressing cylinder 13 to drive the wire cutting and pressing one-way wheel 14 to retract upwards. At this time, the entire wire cutting action process ends, and the fiber filament 24 is fixed at the wire hooking and pressing block 11 and the wire hooking head 17.

[0058] like Figure 5 As shown, it is the state of winding and wire drawing. Figure 1-2 , the entire wire drawing process is:

[0059] In the first step, the valve plate A1 controls the wire drawing and pressing cylinder 9 to push the wire drawing and pressing one-way wheel 10 to press the fiber filament 24 downward to the surface of the core mold 25;

[0060] In the second step, the valve plate E5 controls the wire-hooking pressing cylinder 10 to drive the wire-hooking pressing block 11 to retract upward, and the fiber filament 24 will no longer be fixed at the wire-hooking pressing block 11 and the wire-hooking head 17;

[0061] In the third step, the core mold 25 rotates clockwise for one circle, and the fiber filament 24 is tightly wound around the core mold 25 because the fiber filament 24 is tightly wound around the core mold 25;

[0062] In the fourth step, after the valve plate A1 controls the wire drawing and pressing cylinder 9 to drive the wire drawing and pressing one-way wheel 10 to retract upward, the fiber filament 24 will not slip or fall off on the core mold 25, and the wire drawing action process is completed, and formal winding can begin.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
