Description

Technical Field

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

[0002] Textiles are products made from processed and woven textile fibers. To ensure the quality of textiles, a tensile strength test device is usually used to test the tensile strength of the yarn. The tensile strength test device usually includes a fixed support frame and a mobile stretching device, and the sample is clamped between the two. By applying a gradually increasing tensile force, the material's tensile strength, breaking strength, elastic modulus and other parameters can be tested.

[0003] After searching, the patent with announcement number CN218239630U discloses a cotton textile yarn detection mechanism, which includes a base, an upper bracket is installed on the upper side of the base, a movable tension plate is slidably provided inside one end of the upper bracket, a hydraulic cylinder is installed on one side of the movable tension plate through a tension sensor, yarn end positioning frames are provided on the inner side of the movable tension plate and the upper bracket, and two groups of yarn end positioning frames are horizontally arranged correspondingly, a screw is rotatably provided inside one end of the upper bracket, and one end of the hydraulic cylinder is slidably connected to the screw thread through a slide seat.

[0004] Although the cotton textile yarn testing mechanism mentioned above can perform tension testing on the yarn, since the yarn test needs to be carried out at least three times to ensure the accuracy of the data, when using the yarn testing mechanism, subsequent testing after a single yarn breaks requires straightening a section of the yarn and fixing it again. Since the yarn is thin, it is troublesome to straighten it and inconvenient to use.
