[0029] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0030] Combination Figure 1-Figure 2 As shown, the optical fiber winding device as a preferred embodiment includes a winding component 1 and a cable arrangement wheel 2. Figure 5 As shown, the winding component 1 is intended to wind up the drawn optical fiber monofilament, and includes a screw slide 11 and a winding reel drive seat 12. The winding reel can be installed at the output end of the winding reel drive seat 12. The winding reel drive seat 12 drives the winding reel to rotate to wind up the optical fiber.

[0031] Furthermore, the reel drive seat 12 is installed at the output end of the screw slide 11, and the screw slide 11 can drive the reel drive seat 12 and the reel to slide back and forth, so that the reel can arrange the optical fiber while reeling the optical fiber, so that the optical fiber is neatly reeled on the reel.

[0032] Combination Figure 1 and Figure 2 As shown, the cable arrangement wheel 2 is arranged on one side of the winding component 1 in the direction of the optical fiber, and can guide the optical fiber to be introduced into the winding drum.

[0033] In actual production, the volume of optical fiber preform is large, and the optical fiber drawing lasts for a long time, and may even continue for several days without interruption. However, the winding amount of the reel is fixed. Therefore, the reel needs to be replaced during the drawing process, and the wire cannot be drawn during the replacement process. The drawing of the drawing tower is uninterrupted, resulting in a large amount of waste wire in the process of replacing the reel, causing unnecessary waste.

[0034] Combination Figure 1 and Figure 2 As shown, the cable arrangement wheel 2 is provided with a buffer component on one side of the optical fiber incoming direction, and the buffer component includes a group of fixed wheels 3 and a group of movable wheels 4 arranged in a staggered manner. The movable wheels 4 are configured to be able to slide up and down, and the optical fiber is wound around the fixed wheels 3 and the movable wheels 4 in sequence.

[0035] In this way, when the optical fiber is normally wound, under the action of the winding tension, the movable wheel 4 is supported by the optical fiber to the top of the fixed wheel 3, and the optical fiber can pass through the fixed wheel 3 and the movable wheel 4 in a straight path. When the winding reel is replaced, with the continuous drawing production of the optical fiber and without the winding tension, the movable wheel 4 can gradually slide to the bottom of the fixed wheel 3 under the action of gravity, so that the optical fiber passes through the fixed wheel 3 and the movable wheel 4 in an S-shaped path, forming a temporary storage area for the optical fiber. The optical fiber produced during the time period of replacing the winding reel is stored in the temporary storage area for the optical fiber. After the winding reel is replaced, the optical fiber is rewound, and the winding speed of the winding component 1 is controlled to rewind all the optical fibers in the temporary storage area until the optical fiber passes through the fixed wheel 3 and the movable wheel 4 in a straight path, which can effectively avoid the generation of waste fibers.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, a clamping component 6 for clamping the optical fiber is provided on one side of the cable wheel 2. The clamping component 6 includes a clamping wheel 61, a one-way bearing 62 and a swing arm 63. The clamping wheel 61 is connected to the first end of the swing arm 63 through the one-way bearing 62, so that the clamping wheel 61 can only rotate in the direction of conveying the optical fiber. A driving component 64 is provided at the second end of the swing arm 63.

[0037] In this way, when replacing the winding reel to cut off the optical fiber, the driving component 64 drives the swing arm 63 to swing, so that the pressure wheel 61 is pressed against the optical fiber winding area of ​​the wiring reel 2. After the optical fiber is cut, since the pressure wheel 61 can only rotate in the direction of conveying the optical fiber, the optical fiber is pressed and fixed on the wiring reel 2, which can prevent the optical fiber from escaping from the wiring reel 2. After replacing the new winding reel, the cut part of the optical fiber can be directly fixed on the new winding reel, which is convenient for personnel to operate.

[0038] Furthermore, the driving component 64 includes a servo motor, which has high rotation accuracy and can control the rotation angle using a built-in encoder.

[0039] In an optional embodiment, the pressure wheel 61 is a rubber wheel. The rubber pressure wheel 61 is relatively soft and can deform and wrap around the optical fiber when pressure is applied to the optical fiber, thereby increasing the contact area with the optical fiber and increasing the friction with the optical fiber to prevent the optical fiber from slipping.

[0040] Combination Figure 1 , Figure 2 and Figure 3 As shown, a mounting frame 21 is provided on one side of the wire traversing wheel 2, and the wire traversing wheel 2 and the driving component 64 are both connected to the mounting frame 21. The wire traversing wheel 2 can rotate on the mounting frame 21, and the driving component 64 of the wire traversing wheel 2 is supported by the mounting frame 21.

[0041] Combination Figure 1 and Figure 2 As shown, a mounting seat 5 is provided on one side of the buffer component, and a slide groove 501 corresponding to the number of the moving wheels 4 is opened on the mounting seat 5. The fixed wheel 3 is connected to the top of the mounting seat 5, and the moving wheel 4 is installed in the slide groove 501 and can slide along the slide groove 501. The fixed wheel 3 and the moving wheel 4 can rotate on the mounting seat 5, and the fixed wheel 3 and the moving wheel 4 are supported by the mounting seat 5, and the slide groove 501 can be used to limit and guide the sliding of the moving wheel 4.

[0042] In an optional embodiment, the length of the slide groove 501 is 2.0-3.0 m, and preferably the length of the slide groove 501 is 3.0 m, which can enable the moving wheel 4 to have a longer moving path and increase the optical fiber storage length of the optical fiber temporary storage area.

[0043] Combination Figure 1 As shown, the radii of the arranging wheel 2, the fixed wheel 3 and the movable wheel 4 are all larger than the minimum bending radius allowed for the optical fiber, thereby preventing the optical fiber from being excessively bent when passing through the arranging wheel 2, the fixed wheel 3 and the movable wheel 4, thereby ensuring the quality of the optical fiber.

[0044] In combination with the above embodiments, in the winding design of the embodiment of the utility model, a group of fixed wheels 3 and a group of movable wheels 4 that can slide up and down are arranged on the side of the winding component 1 located in the direction of the optical fiber. When the optical fiber is wound normally, the movable wheel 4 is located above the fixed wheel 3, and the optical fiber passes through the fixed wheel 3 and the movable wheel 4 in a straight line path. When the winding reel is replaced, with the continuous drawing production of the optical fiber, the movable wheel 4 gradually slides to the bottom of the fixed wheel 3, so that the optical fiber passes through the fixed wheel 3 and the movable wheel 4 in an S-shaped path, forming a temporary storage area for the optical fiber. The optical fiber produced during the time period of replacing the winding reel is stored in the temporary storage area for the optical fiber. After the winding reel is replaced, the optical fiber is re-wound, and the winding component 1 is controlled to rewind all the optical fibers in the temporary storage area for the optical fiber until the optical fiber passes through the fixed wheel 3 and the movable wheel 4 in a straight line path, which can effectively avoid the generation of waste fibers.

Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
