[0002] Inorganic FRP air duct is a kind of pipe made of magnesium oxychloride cement as cementing material, medium-alkali glass fiber as reinforcing material, filler material and modifier, etc. Inorganic FRP air duct mainly includes square FRP ventilation pipe and There are two structures of circular FRP ventilation pipes, among which square FRP ventilation pipes are more convenient than circular FRP ventilation pipes in terms of cutting, manufacturing, installation, and construction. At present, the processing of square FRP ventilation pipes is mainly done manually. Hand lay-up operation process, the square FRP ventilation pipe prepared by this process not only has low strength, rough surface and poor quality stability, but also has high labor intensity and serious environmental pollution, which brings great safety hazards to the health of workers. Most of the currently used winding machines are mainly used to prepare underground petroleum pipelines and chemical waste liquid pipelines. The winding process is mainly aimed at products with rotary geometry, which cannot meet the requirements for processing square FRP ventilation pipes, and due to existing Most of the winding machines use mechanical structures to realize motion control, so that the winding accuracy is not high, and cannot meet the processing accuracy requirements of square FRP ventilation pipes. Therefore, the existing square FRP ventilation pipes need to be replaced by automatic processing methods.
