On-line unwinding creel yarn-reversal tension testing system and method of carbon fiber high speed machine

Abstract

The invention discloses an on-line unwinding creel yarn-reversal tension testing system of a carbon fiber high speed machine. The on-line unwinding creel yarn-reversal tension testing system comprisesan unwinding system, a winding system and a testing system, wherein the unwinding system comprises an unwinding shaft and a first power device and used for unwinding of yarn; the winding system comprises a winding shaft and a second power device and used for winding of the yarn; and the testing system is arranged between the unwinding system and the winding system and used for real-timely detecting the change of tension in the winding and unwinding process of the yarn. The testing system comprises a tension wheel and a weighing sensor arranged on the tension wheel. The tension wheel is arranged between the unwinding shaft and the winding shaft. The unwinding shaft and the winding shaft are located in the same horizontal plane. The tension wheel and the unwinding shaft as well as the tension wheel and the winding shaft are located in different horizontal planes. Through the on-line unwinding creel yarn-reversal tension testing system, dynamic simulation of the on-line unwinding creel yarn-reversal process of the carbon fiber high speed machine is achieved, the technical blank in the field is filled up, thus the feasibility of a backing-off control system can be confirmed, the product unqualified rate in the actual production process is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a testing system and testing method for unwinding and unwinding tension of a carbon fiber high-speed machine on-line creel. Background technique [0002] The online unwinding creel and unwinding system of the carbon fiber high-speed machine controls the speed of the unwinding shaft through the single-chip microcomputer voltage regulation unwinding controller and the torque motor, and the output torque of the torque motor directly affects the tension of the yarn during the unwinding process. A dynamic actual simulation test is carried out to confirm whether the power system of the unwinding system meets the control requirements for the tension of the unwinding yarn, but there is no dynamic simulation and detection device for the unwinding system. [0003] In view of the defects in the above-mentioned existing carbon fiber high-speed machine on-line unwinding creel and un...
