Description

Technical Field

[0001] The utility model relates to the field of toughness testing devices, in particular to a spinning toughness testing device. Background Art

[0002] In the spinning production process, the toughness of the spinning needs to be tested to judge the actual performance of the spinning, and then the textiles produced by spinning can be rated. Therefore, the toughness of the spinning, as an important performance indicator, needs to be strictly tested and publicized;

[0003] After checking the publication (announcement) number: CN216051167U, a toughness testing device is disclosed. This technology discloses "including a workbench and a toughness testing machine fixedly installed on the upper surface of the workbench, the upper surface of the workbench is provided with a positioning clamping mechanism, the lower surface of the workbench is provided with a synchronous adjustment mechanism, the positioning clamping mechanism includes two clamp bodies and an air pump, a connecting plate and a partition plate located at the bottom of the connecting plate are fixedly installed in the clamp body, and a multi-stage telescopic rod connected to the connecting plate and not less than six in number is fixedly installed on the lower surface of the connecting plate. The toughness testing device, by setting a positioning clamping mechanism, can adapt to the clamping of samples of different shapes, and can also limit the rolling of the sample when facing a cylindrical sample, thereby improving the test stability, and by setting a synchronous adjustment mechanism, the position of the clamp body can be synchronously adjusted, thereby ensuring that the lower pressure head of the toughness testing machine can always be kept in the middle position of the sample to avoid test errors";

[0004] In the above-mentioned comparative documents, during the toughness test, since spinning of different lengths cannot be done evenly in all parts, the weak points of spinning are different, resulting in more weak points for spinning with longer lengths, which in turn leads to deviations in the actual measurement data. If a short spinning line is used for testing, the distribution of weak points will be uneven, which will lead to different test results. Therefore, a large number of test experiments are required, and it will take a lot of time to continuously measure the length, cut off and then install the test.

[0043] Working principle:
