[0006] Using the above technical solution, the plastic tube is driven from the left centering and rounding bracket group through the main shaft transmission mechanism through the first cylinder to the right centering and rounding bracket group. At the same time, the fiber strip on the angle-adjustable material tray is melted by multiple sets of combined curved hot air guns and tightly bonded to the plastic tube to form a new type of pipe. Servo control accurately corrects the angle, and the material tray is driven by a servo motor to achieve stepless adjustment within the range of 10° to 80°, meeting the differentiated requirements of the axial strength of the composite pipe ring. The centering and rounding bracket group solves the problem of concentricity and roundness of pipes with different outer diameters, ensuring that the center of the pipe is always on the same horizontal line during pipe production, thereby further improving the roundness of the pipe.

[0014] Using the above technical solution, the curved multi-mesh heater is designed to fit the winding surface in an arc shape to ensure heating uniformity (temperature difference ≤2℃). Then, the multi-mesh mechanism is combined with a high-speed bursting fan to achieve airflow penetration heating with a heating rate of up to 20℃ / s, which shortens the resin curing time.
