Abstract

The invention provides a device for forming a basalt fiber-wound composite pipe. The device comprises a fiber unwinding part, a tension control part, a glue dipping part and a fiber winding part. Thefiber unwinding part comprises an unwinding roller, an unwinding shaft and a torque motor. The tension control part comprises a main speed roller, a magnetic powder brake and a tension detection mechanism. The glue dipping part comprises a glue dipping pool, a glue dipping roller and a glue extrusion roller. The fiber winding part comprises a rack, incomplete gears, a bevel gear reversing mechanism, a supporting table, a guide rail, a guide wheel, the composite pipe, a mandrel, a three-jaw chuck and a yarn nozzle, wherein the two sides of the rack are each provided with one incomplete gear, the yarn nozzle is fixed to the rack, and the bevel gear reversing mechanism drives the incomplete gears to rotate synchronously. According to the device, a horizontal structure is adopted to prevent manual interference of all the parts, so that the stability is high; the tension can be kept constant all the time in the fiber winding process, it is guaranteed that basalt fibers are uniformly wound on the surface of the composite pipe, and the physical properties of the composite pipe are improved.

Description

technical field [0001] The invention relates to a composite pipe surface fiber winding device used in the field of basalt fiber winding. Background technique [0002] Fiber-reinforced composite pipe is an integrated composite pipe formed by regularly winding fibers on the outer surface of the pipe. Fiber-wound products have a significant effect on the mechanical properties and physical properties of the reinforced material, improving the performance of the material in engineering. [0003] Currently, filament winding usually uses carbon fibers. Carbon fiber has high strength and light weight, but carbon fiber is a brittle material, and it will break directly if it is too strong. After damage, it cannot be repaired and can only be replaced. At the same time, the content of harmful chemical components is high, which is not conducive to environmental protection. Basalt fiber is a new type of inorganic fiber material with good performance. After the natural basalt rock is melte...

[0004] At the same time, due to the continuous reduction of fibers during the winding process and the vibration between the various mechanical systems, the tension during the winding process will not be constant. The quality of the entire fiber winding product has a great influence. If the tension between the fiber bundles is not equal when winding, the local fiber strength may be insufficient when subjected to external loads, which will affect the overall strength and cause damage to the winding product.
