Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to an automatic wire laying device for processing an S-shaped air inlet of a carbon fiber composite material aircraft. Background Art

[0002] The air intake duct is an important component of the full-size afterburner tester. The main function of the air intake system is to mix the low-temperature air supply with the high-temperature air supply according to the test requirements, and then provide stable-flowing high-temperature gas for the inlet of the inner and outer culverts of the afterburner. Wire laying is required during the processing of the aircraft's S-shaped air intake duct because wire laying can enhance the structural strength and durability of the duct and prevent the duct from being damaged or deformed due to vibration and airflow pressure during high-speed flight.

[0003] According to the Chinese patent publication number: CN214606012U, a fiber laying device for processing a carbon fiber composite jet aircraft air intake includes a conveyor belt, a conveyor belt roller, and a heating device.

A grouping block is provided on the upper surface of the conveyor belt, and a heating device is provided on the upper surface of the conveyor belt. Clamp protective shells are fixedly connected to both sides of the conveyor belt, and a sliding rod is fixedly connected to the upper surface of the conveyor belt, and a cutting knife is movably connected to the outer wall of the sliding rod. Fiber filaments are provided inside the grouping block. The utility model facilitates the solution of the clamping of fiber filaments in the production process, thereby solving the problem of fiber filament tension, and plays a key role in improving production efficiency, improving component quality, and reducing costs.

[0004] The above scheme still has the following disadvantages: a sliding rod is fixedly connected to the upper surface of the conveyor belt, a cutting knife is movably connected to the outer wall of the sliding rod, and fiber filaments are arranged inside the grouping block. In the document of the application, a cutting knife is used to cut the laid fiber filaments, and some harmful small particles will be generated during the cutting.

Therefore, the generated small particles need to be absorbed and cleaned during the wire laying and cutting process.
