TECHNICAL FIELD
[0001] The utility model relates to a fiber coil winding auxiliary structure, concretely relates to a harrow auxiliary device. BACKGROUND
[0002] In winding the fiber ring, the fiber needs to be arranged in order. With the increase of the fiber layer, each fiber layer is constrained by the previous fiber layer, which makes it difficult for the new fiber layer to completely adhere to the previous fiber layer, resulting in uneven fiber surface of the fiber ring. To solve this problem, a harrow is used for fiber protection and fiber pressing operation to ensure the flatness of the fiber surface. However, when performing "layer skipping" operation (i.e. when the current fiber layer is wound and the outer fiber winding is about to start), the harrow needs to be moved to a certain position away from the current fiber layer to prepare for the winding of the next layer of fiber. However, before the next layer of fiber is wound, the harrow temporarily separates from the fiber, so that the fiber is in an unconstrained state at this time. In this state, the winding of the end of the fiber layer is prone to slipping, which affects the winding quality and the overall flatness of the fiber ring.
[0003] To solve this problem, the operation process and design of the harrow need to be optimized to ensure that the fiber always stays in the ideal position during the layer skipping process and prevent the occurrence of slipping phenomenon, thereby improving the winding quality of the fiber ring. SUMMARY
[0004] The utility model aims at providing a harrow auxiliary device, and the technical problem to be solved is how to solve the slipping problem that occurs easily when winding the end of the fiber layer, so as to improve the winding quality and the overall flatness of the fiber ring.

[0007] The angle between the rake and the skeleton is adjusted by the rotating disc, and the distance between the rake and the skeleton is adjusted by the telescopic structure, so as to adapt to the demand of optical fiber rings of different diameters. Especially in the process of layer transition, the telescopic structure helps the rake to transition from one optical fiber layer to another, ensuring the continuity and stability of the operation and reducing the risk of optical fiber slipping; the rake is adjusted in angle by the rotating structure, and the face of the rake for contacting the optical fiber is changed by self-rotation; the telescopic structure and the rotating structure are arranged on the rotating disc, and in the process of layer transition, the telescopic structure gradually moves away from the current optical fiber layer, while the rotating structure drives the rake to self-rotate, so that the rake is always in contact with the optical fiber and applies pressure to the optical fiber, and at the same time, the winding of the current optical fiber layer is continued; when the telescopic structure stops, the rotating structure also stops, and at this time, the rotating structure rotates to a preset position; then the winding of a new layer of optical fiber is started. Through the cooperation of the telescopic structure and the rotating structure, the rake can always maintain contact with the optical fiber during the layer transition process, providing continuous support and constraint to prevent the optical fiber from slipping and ensuring the neatness and stability of the optical fiber arrangement.

By adjusting the relative position between the first disc and the second disc, various sizes of optical fiber rings can be more flexibly adapted, improving the versatility and scope of application of the equipment; after the desired angle is set, tightening the bolts can fix the first disc and the second disc, ensuring that unnecessary movement does not occur during winding, not only enhancing the stability of the system, but also ensuring the consistency and reliability of the winding process.

[0020] The connecting assembly separates the first driver and the second disc, so that the two components can be independently manufactured and tested, and then assembled, which not only simplifies the production process, but also facilitates subsequent maintenance and replacement; the first connecting plate is closely attached to the second disc, so as to ensure the relative position of the first driver on the disc, and ensure that each transition can be performed in the optimal state during the layer transition operation.
[0021] Further, one end of the sliding block connected with the telescopic shaft is connected with the rotating structure.
[0022] The rotating structure comprises a second driver and a rotating shaft, and an output end of the second driver is connected with the rotating shaft; and the rotating shaft is used for connecting the rake.

[0026] A screw hole is formed in the limiting block, the fine adjustment screw is threadedly connected with the screw hole, and the fine adjustment screw extends towards the gap through the screw hole.
[0027] Further, the side wall of the first disc is provided with a limiting column, and the limiting column is inserted into the gap.
