Description

Technical Field

[0001] The utility model relates to the technical field of yarn length meters, in particular to a yarn length meter with constant tension. Background Art

[0002] A constant tension yarn length meter may be a special instrument used to measure the length of a yarn while maintaining a constant tension. However, the specific implementation methods and functions may vary among different manufacturers and models. In terms of the working principle of a tension meter, it is usually based on Hooke's law, that is, the deformation of an elastic body when subjected to a force is proportional to the magnitude of the force. The tension meter indirectly measures the magnitude of the force by measuring the deformation of the material when subjected to a force. For a constant tension yarn length meter, it may combine the functions of tension control and length measurement to ensure that the tension of the yarn remains unchanged during the measurement process, thereby obtaining a more accurate length measurement result. The yarn length meter needs to maintain a constant tension when measuring the length of the yarn to avoid affecting the accuracy of the measurement. The tension adjustment mechanism of the existing yarn length meter is troublesome to adjust the tension, inconvenient to operate, and affects work efficiency. To this end, the utility model provides a constant tension yarn length meter. Utility Model Content
