Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber drawing process equipment, in particular to an optical fiber winding device for preventing loosening. Background Art

[0002] Optical fiber is a fiber filament made of glass or plastic that can be used as a light transmission tool. It uses an optical fiber preform rod, which is then heated and softened in a high-temperature furnace in a drawing tower, drawn into a filament, and then annealed, cooled, coated, cured, and twisted to become an optical fiber core wire, which is finally wound and rolled up.

[0003] When the optical fiber is being wound, in order to ensure that it is wound tightly and not loose, a set of tension control equipment will be set up at the winding process to apply tension to the optical fiber at the winding point and adjust the tension in real time. The optical fiber at the tension control equipment will be subjected to greater pulling force, and the optical fiber drawing process will last for a long time during the drawing production, and may even continue for several days without interruption. This makes it inevitable that the wire will break at the tension control equipment. Once the wire breaks, although the winding shaft stops in time, the optical fiber on the winding shaft has no tension limit, and it is easy to become loose under the action of its own elastic recovery force. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the first aspect of the utility model provides an anti-loosening optical fiber winding device, comprising:

[0005] A winding component is used to drive the winding reel to rotate and wind up the optical fiber;

[0012] Preferably, a flange having the same cross-section as that of the guide wheel groove is provided on the inner side of the pressure strip.

[0013] Preferably, the arc length of the pressure strip is greater than the arc length of the arc-shaped contact area.

[0028] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0029] Combination Figure 1-Figure 4 As shown, the optical fiber winding device of the exemplary embodiment of the utility model includes a winding component 10, a guide wheel 20, a clamping component 30 and a tension control component 40. The winding reel is installed on the winding component 10, and the winding reel is driven by the winding component 10 to rotate and wind up the optical fiber. The tension control component 40 is located on one side of the winding component 10 and can apply winding tension to the optical fiber to make the optical fiber wind tightly. The guide wheel 20 is located between the winding component 10 and the tension control component 40. The optical fiber passes through the guide wheel 20 and is introduced into the winding component 10 for winding, and forms an arc-shaped contact area with the guide wheel 20.

[0030] When the optical fiber is being wound, in order to ensure that it is wound tightly and not loose, a set of tension control equipment will be set up at the winding process to apply tension to the optical fiber at the winding point and adjust the tension in real time. The optical fiber at the tension control equipment will be subjected to greater pulling force, and the optical fiber drawing process will last for a long time during the drawing production, and may even continue for several days without interruption. This makes it inevitable that the wire will break at the tension control equipment. Once the wire breaks, although the winding shaft stops in time, the optical fiber on the winding shaft has no tension limit, and it is easy to become loose under the action of its own elastic recovery force.

[0031] Combination Figure 2 and Figure 3As shown, a clamping component 30 is provided on one side of the arc-shaped contact area formed by the contact between the optical fiber and the guide wheel 20. The clamping component 30 includes a connecting plate 31 and a pressure strip 32. The connecting plate 31 is configured to be able to elastically rotate relative to the arc-shaped contact area. The connecting plate 31 has an open state and a closed state. The pressure strip 32 is fixed on the inner side of the connecting plate 31, and the pressure strip 32 is configured to be an arc corresponding to the wire groove of the guide wheel 20.

[0032] Thus, when the optical fiber is under winding tension, the connecting plate 31 is supported to an open state (such as Figure 2 As shown), the guide wheel 20 can rotate normally to guide the optical fiber; when the optical fiber is broken and there is no winding tension, the connecting plate 31 rotates to a closed state under the action of elastic force, and the pressure strip 32 is pressed into the wire groove of the guide wheel 20 (as shown). Figure 3 As shown in the figure, the optical fiber in the arc-shaped contact area is compressed by elastic force to prevent the tightly wound optical fiber from loosening due to the optical fiber being pulled out.

[0033] Furthermore, the first end of the connecting plate 31 is connected to a supporting wheel 33, and the optical fiber supports the connecting plate 31 in an open state through the supporting wheel 33, so that when the optical fiber supports the connecting plate 31, it contacts the supporting wheel 33, reducing the friction of the optical fiber.

[0034] In an optional embodiment, the connecting plate 31 is configured to be an arc shape corresponding to the shape of the pressure strip 32 , so as to better apply pressure to the pressure strip 32 .

[0035] Combination Figure 4 As shown, the inner side of the pressure strip 32 is provided with a flange 321 with the same cross-section as the wire groove of the guide wheel 20. Preferably, the cross-section of the flange 321 is an isosceles triangle, so that the pressure strip 32 can better extend into the wire groove of the guide wheel 20 to stably clamp the optical fiber.

[0036] In an optional embodiment, the pressure strip 32 is a rubber pressure strip, which is relatively soft. When the pressure strip 32 is pressed into the wire groove of the guide wheel 20, it can be deformed and wrapped around the outside of the optical fiber to increase the contact area, thereby improving the clamping stability.

[0037] Combination Figure 1 As shown, a support frame 50 is provided on one side of the winding component 10 , and the guide wire wheel 20 and the tension control component 40 are both connected to the support frame 50 , and the guide wire wheel 20 and the tension control component 40 are supported by the support frame 50 .

[0038] Combination Figure 2 and Figure 3As shown, the support frame 50 is connected to the mounting frame 51 at the position of the guide wheel 20, the connecting plate 31 is connected to the mounting frame 51, the second end of the connecting plate 31 is connected to a rotating shaft with an elastic member, and the second end of the connecting plate 31 is rotatably connected to the mounting frame 51 via the rotating shaft. Under the action of the elastic member, the connecting plate 31 can be rotated from an open state to a closed state, and the pressure strip 32 can be pressed against the optical fiber.

[0039] In an optional embodiment, the aforementioned elastic member is a torsion spring.

[0040] In combination with the above embodiments, the utility model proposes an anti-loosening optical fiber winding device, in which a clamping component 30 is arranged at the guide wheel 20, and the clamping component 30 includes a connecting plate 31 and a pressure strip 32. When the optical fiber has winding tension, the connecting plate is supported to an open state under the action of the tension, and the guide wheel 20 can rotate normally at this time to guide the optical fiber; when the optical fiber is broken and there is no winding tension, the connecting plate 31 rotates to a closed state under the action of elastic force, and the pressure strip 32 is pressed into the wire groove of the guide wheel 20, and the optical fiber located in the arc contact area is clamped by elastic force to prevent the tightly wound optical fiber from loosening due to the optical fiber being pulled out.

[0041] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
