Description

Technical Field

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

[0002] The filament winding process is an advanced composite material manufacturing technology. This technology has many significant characteristics and advantages, such as easy mechanization and automation, providing good labor hygiene conditions, reducing labor intensity, ensuring the stability of product quality, and reducing 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. In the process of wet winding, in the winding preparation stage before fiber winding, the fiber thread needs to be passed through the threading hole on the winding machine and stabilized in the fiber yarn position of the winding machine. 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 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 sticking to the threading hole further increases the difficulty of threading, and it is easy to cause fiber fuzzing during subsequent winding, affecting the quality of the product.
