[0002] The diameter of xuanshi fibers obtained after high-temperature drawing of xuanshi is in the micron order of magnitude. When xuanshi is fibered, its strength is greatly increased, and its mechanical properties far exceed those of aramid fibers, carbon fibers, glass fibers, and ultra-high molecular weight polyethylene fibers.

[0003] However, for the processing of xuanshi fibers, there is currently no mature continuous processing device. During the processing of fiber cloth, problems such as deviation, wrinkles, or flanging are likely to occur. In order to ensure that the fiber cloth maintains a specific shape when entering the thermosetting mold to prevent affecting the thermosetting of the fiber cloth and the resin matrix, thereby causing a decrease in the mechanical properties of the xuanshi fiber composite material, we provide a pultrusion and thermosetting device for xuanshi fibers. Content of the Utility Model

[0004] To solve the problem in the above background technique that the fiber cloth cannot be well shaped before thermosetting, resulting in the fiber cloth being prone to deviation, wrinkles, or flanging, which affects the thermosetting of the fiber cloth and the resin matrix, and further leads to a decrease in the mechanical properties of the xuanshi fiber composite material, the utility model provides a pultrusion and thermosetting device for xuanshi fibers.

[0028] The pultrusion heat curing assembly includes two groups of fixing plates symmetrically and fixedly connected to one side of the sand frame 1.

[0029] The implementation principle of a pultrusion heat curing device for basalt fibers in the embodiment of the present application is as follows: First, place multiple fiber cloths between the roller 2 and the leveling rod 3 on the same horizontal line.
