A device and method for measuring yarn torque through a free rotor

Abstract

The invention discloses a device and method for measuring yarn torque through a free rotor. The device includes a box body, a computer component, a torque detection component and a fixing component arranged in the box body; the torque detection component includes one end and The rotor assembly connected by the yarn and the photogate sensor arranged on the side of the rotor assembly, the photogate sensor is connected with the circuit board wire fixed on the box, and the photogate sensor is used to obtain the Angular velocity; the fixed part is composed of a base, a lifting platform, a rotating shaft and a beam; the computer assembly line is connected on a circuit board. Through the above method, the present invention can perforate and knot the yarn on the rotor positioning member, and hang it freely, so that the torque can be fully released, and the rotor is driven to rotate. After the photoelectric gate sensor measures the angle of the rotor, it is connected to the circuit board through the wire. The computer component analyzes and processes to obtain the torsion force of the yarn, which greatly improves the measurement accuracy.

Description

Technical field [0001] The present invention relates to a detecting device, and more particularly to a device and method for measuring yarn torque by free rotor. Background technique [0002] At present, a plurality of single-strand lines need to be twisted during the production of yarns. When the strand is twisted to its surface fiber, the whole strand is not zero; this yarn is formed into a fabric Under all yarn torque, the fabric occurs. [0003] The weft is one of the mandatory detection indicators of fabric quality, because it will have a serious adverse effect on the cropping of the fabric and the appearance of clothing. Therefore, the factory generally decreases the torque of the strand to a reasonable range by steaming yarns, but does not completely eliminate this torque. However, in the actual production process, under the same steam condition, the same type of different batches (such as cotton, nominal red line or white line or white line) is finally not shaped, and the...

Problems solved by technology

[0007] In order to overcome the problems of low detection accuracy, complex detection process and high cost of the existing yarn torque detection device, the present invention provides a rotor with fixed moment of inertia, through which the yarn is perforated and knotted on the rotor positioning part, and it hangs freely , so that the torque can be fully released, and the rotor is driven to rotate. The photoelectric gate sensor measures the angle of the rotor, and after the analysis of the computer components, the torque of the yarn is obtained, which greatly improves the measurement accuracy.
