[0002] Fiber bundle unwinding is the primary link in the mechanized fiber spreading equipment to carry out fiber bundle widening and forming. The accuracy of fiber bundle tension control directly represents the development level of fiber spreading mechanical equipment. However, with the gradual improvement of textile machinery and equipment and its development towards automation and intelligence, precision control and automation technology have been put on the agenda, and the overall fiber bundle tension control method and strategy have gradually highlighted their shortcomings, especially in the field of fiber spreading, prepreg, etc., which require precise tension control of a single fiber bundle. Therefore, realizing electrical control of fiber bundle tension is the development direction of the existing automated control of textile machinery and equipment. It relies on sensors to collect information, and after the main controller processes the information and outputs the signal, it can precisely control a single fiber bundle. Moreover, if you want to achieve tension control of multiple fiber bundles to improve efficiency, you need to design a control system that integrates multiple channels, and often multiple channels use unified PID control parameters. For control systems with high tension requirements, their production quality is low, and the PID control parameters of a single channel cannot be adjusted to meet actual needs.

[0003] There is an urgent need for a multi-channel fiber bundle unwinding tension control system for fiber spreading. Each channel is independently controlled. The closed-loop control PID parameters of each channel of this system are independently adjustable. The PID control parameters can be changed and adjusted at any time to ensure that the tension control of each channel is more precise, effectively solving the problem of difficulty in controlling single yarn tension in the textile field, and achieving controllable and adjustable yarn tension values ​​within a small range, effectively reducing labor intensity and improving the level of automation. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a fiber bundle unwinding tension control system for fiber spreading, which is mainly used to drive the magnetic powder brake. The second host computer module presets the tension value, and the fiber bundle unwinding tension system is independently started / stopped by remote control of the first host computer module, so as to achieve the adjustment of each unwinding tension and the closed-loop control of the tension value fluctuation within the specified range. The whole system realizes the adjustment of the fiber bundle unwinding tension working state through electronic control, reduces the labor intensity, realizes the precise output torque of the magnetic powder brake, and achieves the function of constant tension unwinding. At the same time, the closed-loop control PID parameters of each channel of the system are independently adjustable, and the PID control parameters can be changed and adjusted at any time to ensure that the tension control of each channel is more precise.
