AI Technical Summary
In existing CPP film edge-winding devices, the edge strip is prone to breakage during the winding process due to uneven tension at the end, resulting in uneven stress in the middle.
A wind pressure traction mechanism is adopted, which uses a fan to send air into the three-way pipe to generate negative pressure, which pulls the CPP film edge strip to move in the edge-gathering pipe, ensuring that the edge strip is evenly stressed throughout the edge-gathering process.
This effectively prevents the edge strip from breaking due to uneven stress in the middle during the winding process, thus improving the stability and reliability of winding.
