Description

Technical fields:

[0001] This utility model relates to a winding machine, and more particularly to a winding machine specifically for narrow strip prepreg. Background technology:

[0002] Currently available prepreg winding machines primarily use a spindle and a driven shaft to clamp and rotate the workpiece, while the winding device is fixed on a horizontal moving mechanism to achieve workpiece winding. The rotation of the spindle clamping the workpiece generates centrifugal force, and the longer the spindle, the greater the centrifugal force. Therefore, the spindle of this type of winding machine cannot be too long, limiting the length of the workpiece and making it impossible to achieve high-precision winding of workpieces exceeding a certain length. Moreover, winding can only be achieved at a single winding station, resulting in low efficiency.

[0003] Meanwhile, existing winding machines do not include a control system, making it impossible to accurately control key parameters such as winding tension, travel distance, and speed. Utility Model Content:

[0004] The purpose of this invention is to overcome the shortcomings of existing winding machine technology and provide a narrow-strip prepreg winding machine that can achieve high-precision winding of long workpieces and improve winding efficiency. It also enables precise control.
