Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0057] A method for maintaining the tension of fiber yarns in groups, comprising the following steps: supplying power to a group of motors through the same three-phase voltage regulator. In the present invention, a torque motor is used, and the synchronous motor of the contactor voltage regulator is used to control carbon The brush slides along the surface of the coil, and adjusts the turns ratio to output the effective value of the voltage. The output voltage waveform is a sine wave, which avoids the risk of harmonic interference; calculates the real-time roll diameter of the unwinding roller; according to the required yarn tension and Calculate the required output v...

Abstract

The invention relates to the technical field of fiber yarn tension control, in particular to a method for maintaining fiber yarn tension in groups, comprising the following steps: supplying power to a group of motors through the same three-phase voltage regulator; Real-time winding diameter; calculate the required output voltage of the motor according to the required tension of the yarn and the real-time winding diameter; adjust the output voltage of a group of motors to the required output voltage through a three-phase voltage regulator. In the present invention, the voltage of a group of motors is controlled by the same three-phase voltage regulator, so that the motors in the group output the required output voltage under the same yarn tension, and the voltage changes in real time with the winding diameter of the yarn bobbin, effectively The consistency and stability of the multi-strand yarn tension are ensured. When the above method is applied to a bundle of flat filaments, it can ensure that there are no gaps in the bundle and the quality of the final fabric. At the same time, the present invention also claims a system for maintaining the tension of fiber yarns in groups, which has the same technical effect.

Description

technical field [0001] The invention relates to the technical field of fiber yarn tension control, in particular to a method and system for maintaining fiber yarn tension in groups. Background technique [0002] The carbon fiber production line needs to be warped before weaving. It is necessary to put the carbon fiber yarn through several processes of yarn laying, yarn collection, fiber spreading, heating and winding, and warp the single yarn into a flat filament of a certain width, and combine it with other yarns To form a semi-finished product with good consistency and good consistency, it is required in terms of quality control that there should be no gaps in the middle of the flat wire. In order to meet the above requirements, in the process of unwinding the yarn in the first process, it is necessary to maintain the uniform tension of each yarn. Stability control is difficult. [0003] In view of the existence of the above problems, based on years of rich practical exp...
