AI Technical Summary
Technical Problem
Existing composite material winding equipment cannot effectively adjust the tension of the strip material, resulting in a decrease in winding quality.
Method used
The torque of the tension roller is controlled by a magnetic powder brake. The tension of the material belt is adjusted by the friction between the tension roller and the surface of the material belt. The tension is also adjusted in real time by combining a pressure sensor and a second magnetic powder controller.
Benefits of technology
It enables precise adjustment of the strip tension, improving the winding quality and efficiency of composite materials.

Abstract
The application discloses a kind of composite winding device, comprising: support frame, pay-off roll, with support frame rotation connection, for placing roll to discharge material.The tension roller is rotatably connected with the support frame and is arranged on one side of the pay-off roll.The first guide roller is rotatably connected with the support frame and is arranged between the pay-off roll and the tension roller.The second guide roller is rotatably connected with the support frame and is arranged on both sides of the tension roller with the first guide roller, for pressing the tape of the roll on the surface of the tension roller.The first magnetic powder brake is coaxially fixedly connected with the output shaft of the tension roller, and the tension of the tape is adjusted by controlling the torque of the tension roller.The contact area between the tension roller and the surface of the tape is large, and the tension of the tape is controlled by controlling the torque of the tension roller by the magnetic powder brake, pulling the tension roller by the friction force of the tape surface on the tension roller, so as to accurately adjust the tension of the discharge material and improve the winding quality of the composite material.
