[0002] FRP mesh is a mesh made of fiber-reinforced composite materials. It is light and hard, non-conductive, has high mechanical strength and corrosion resistance. Due to its excellent mechanical properties, it is widely used in bridge engineering, various construction projects, marine engineering, underground engineering and other projects.

[0003] At present, when producing FRP mesh, multiple FRP wires are usually tied and fixed, and then cut, glued, dried and other processes are combined to form a mesh structure. Before production, in order to facilitate access, the FRP wires used to form the mesh are generally stored in a rotatable wire feeding reel, and the wires are retracted and released by rotating the wire feeding reel.

[0004] However, the existing wire feeding reels generally have a relatively fixed diameter. When placing the wire, it is necessary to adjust the wire according to the wire feeding reel to prevent the wire from being tensioned. Before the wire is placed in the wire feeding reel, its storage specifications are not consistent. Therefore, manual adjustment is required almost every time a new wire is placed, which is time-consuming and labor-intensive, resulting in long-term labor occupation and indirectly increasing labor costs.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Utility Model Content
