Abstract: The invention discloses a rigid-flexible coupling mechanism with variable rod length for fibre bundle tension control. In the transmitting process, the fibre bundle passes through the front guide roller, the tension regulating roller and the back guide roller sequentially. The front and back guide rollers have fixed positions, while the tension regulating roller has an adjustable position to regulate the fibre bundle tension. The invention uses the variable rod length rigid-flexible coupling mechanism with a combination of a servo motor and an electric actuator in a dual drive control mode, which can choose to use either a four-rod fixed length mechanism or a five-rod variable length mechanism to regulate the tension under different working conditions. This provides a more flexible control method, increases the regulating range of fibre bundle tension, improves the system response speed and regulation accuracy, and effectively avoids the wear of fibre bundle caused by tension fluctuations.
