Description

Technical Field

[0001] The present invention relates to the technical field of fiber winding, in particular to a wire threading device and a winding machine. Background Art

[0002] Filament winding is an advanced composite material manufacturing technology with many significant features and advantages, including ease of mechanization and automation, provision of good labor hygiene conditions, reduction of labor intensity, assurance of product quality stability, and reduction of production costs.

[0003] The fiber winding process is mainly divided into dry winding and wet winding. Wet winding is to soak the fiber bundle in resin and then directly wind it onto the core mold under tension control. During the wet winding process, in the winding preparation stage before fiber winding, the fiber thread end needs to be passed through the threading hole on the winding machine and stabilized in the fiber yarn position of the winding machine. Among them, passing the fiber through the threading hole on the winding machine is usually done manually, which is difficult to operate and has poor stability. The fiber and the resin on the fiber are easy to come into contact with the threading hole on the winding machine, causing the resin to stick to the threading hole or the fiber to wear. The resin adhering to the threading hole further increases the difficulty of completing the threading, and is likely to cause fiber fuzzing during subsequent winding, affecting the quality of the product.
