Description

Technical Field

[0001] The utility model relates to the technical field of yarn detection, in particular to a yarn tension detector. Background Art

[0002] In the textile production process, yarn tension directly affects the quality of the product. Unstable yarn tension is not conducive to the weaving of fabrics, and the existence of broken threads will cause product defects and increase the defective rate. Therefore, in order to ensure the processing quality, it is necessary to detect the tension of the yarn. The yarn tension detector is a detection device used to stretch and detect the tension of the yarn.

[0003] After searching, the existing Chinese patent with publication number CN202221304411.6 discloses a wool sweater yarn tension detection device, which realizes the technical effect of simultaneously stretching the two ends of the yarn through a set of gears, replacing the conventional design of two sets of cylinders pulling to both ends at the same time, and cooperates with the obliquely engaged triangular elastic engaging blocks, which not only ensures the pulling effect on the yarn, but also realizes the design function of conveniently observing the tension data when the pulling force of the yarn is too large.

[0004] The above technical solution has the following defects: although such a yarn tension detector can clamp the yarn through the clamping structures at both ends and stretch the yarn by driving the tooth block through the gear, such a yarn tension detector needs to manually position the yarn one by one during actual use, and only one group of yarn can be detected. In order to ensure the detection effect, it is usually necessary to detect multiple groups of yarns. In order to further improve the maintenance efficiency of yarn tension detection, a yarn tension detector is proposed, which is provided with multiple detection stations, and can load and synchronously detect the tension of multiple groups of yarns, so as to facilitate the loading and positioning of the yarn and make the yarn detection work more convenient.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
