[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 combined with cutting, gluing, drying and other processes to form a mesh structure. In order to achieve high automation of mesh production, the binding, gluing, cutting and drying equipment are often incorporated into the same production line. In the mesh production line, the transportation of the mesh is generally driven by a simple transmission mechanism, which makes it difficult to ensure that the mesh movement rate is compatible with each mechanism, and the stability of the transmission rate is also difficult to ensure; at the same time, when conventional transportation mechanisms transport mesh cables, if a clamping device is used, it is easy to damage the mesh cables due to uneven distribution of clamping force on the wires.
