AI Technical Summary
Technical Problem
Traditional air shafts are difficult to use for cylindrical winding of substrates and require an additional core assembly process, which affects winding efficiency.
Method used
Design an air-expanding shaft with an arc-shaped plate. Through the cooperation of the arc-shaped plate and the telescopic key, a ring shape is formed. The substrate is directly wound around the arc-shaped plate to achieve cylindrical winding and simplify the process.
Benefits of technology
It enables cylindrical winding of the substrate, simplifies the equipment structure and winding process, and improves winding efficiency.
