Description

Technical Field

[0001] The utility model mainly relates to the technical field of fiber production and processing, and in particular to a device for frosting the surface of flame-retardant fibers. Background Art

[0002] Light-flame-retardant polyester-nylon composite fiber rebars can be used for a long time in acid, alkali, salt and humid environments. Compared with steel bars, they have a longer service life in these environments. They are widely used in subway underground continuous walls, highway and railway foundation protection, building protection and other fields. However, the current composite fiber rebars have a high surface smoothness and are not easy to fit tightly with concrete during use, so surface frosting treatment is required during production.

[0003] After searching, the patent with application number CN202121869263.8 provides a surface frosting treatment device for matte flame-retardant polyester-nylon composite fibers. The device can automatically frost the composite fibers, but the device has certain shortcomings. For example, the gap between the frosting ring and the traction wheel of the device cannot be adjusted, resulting in the inability to handle flame-retardant fibers of different thicknesses well. When the flame-retardant fiber is thin, the traction wheel cannot be pulled well, and the frosting ring has insufficient contact with the flame-retardant fiber, affecting the frosting effect. When the flame-retardant fiber is thick, the frosting ring is excessively in contact with the flame-retardant fiber, affecting the quality of the flame-retardant fiber. Utility Model Content
