Tension calibration calculation method and device

Abstract

The invention relates to the technical field of composite materials, in particular to a tension calibration calculation method and device, and the method comprises the steps: arranging a tension roller; the tension roller is emptied, and a first signal on the tension sensor is read; fixing one end of the fabric, connecting the other end with a weight, enabling the fabric to pass through the tension roller, and forming an included angle between the two ends; calculating the weight of a required weight when the tension sensor is in a full scale; when the fabric is connected with a weight of the full-scale weight of the tension sensor, a second signal on the tension sensor is read, and the weight of the weight corresponds to the full-scale tension; during production, the fabric passes through the tension roller at the included angle, a real-time signal on the tension sensor is read, and the real-time tension on the fabric is calculated according to the proportion of the real-time signal between the first signal and the second signal and the full-scale tension. The device can adapt to different installation positions and modes of the tension sensor, the real-time tension on the yarn is calculated, the error between the measured value on the tension sensor and the real tension is eliminated, and the production quality is improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a tension calibration calculation method and device. Background technique [0002] In the production of composite materials, the tension of the cloth surface not only has a decisive effect on the winding effect, but also affects key parameters such as the width and diameter of the cloth roll. tension control. [0003] In the prior art, a tension sensor is usually used to detect the tension of the cloth surface. However, the way and position of the tension sensor are different, which will affect the tension detected on the tension sensor. There is an error in the tension of the cloth, so the tension needs to be calibrated. The calibration of the cloth surface tension determines the authenticity of the feedback tension. [0004] In view of the existence of the above problems, the designer based on many years of rich practical experience and professional knowledge in t...

[0003] In the prior art, the tension sensor is usually used to detect the tension of the cloth surface, but the way and position of the tension sensor are different, which will affect the tension detected on the tension sensor, resulting in the tension feedback on the tension sensor and the actual tension on the cloth surface. There is an error in the tension of the fabric, so it is necessary to calibrate the tension. The quality of the calibration of the cloth surface tension determines the authenticity of the feedback tension.
