Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and particularly relates to a strength detection device for high-temperature resistant nylon threads. Background Art

[0002] Generally, the use environment of ordinary nylon threads is below 100 °C. However, by adding stabilizers and other methods, the high-temperature resistance of nylon threads can be improved to meet the use environment above 100 °C. However, if there are problems with the addition amount of stabilizers or the production process, it will affect the strength and service life of nylon threads. Therefore, it is necessary to detect the strength of nylon threads in each production batch to avoid unqualified products.

[0003] In the prior art, a nylon thread multi-diameter tensile test device with the publication number of CN110514515A discloses a test device for detecting the tensile strength of nylon threads by using a motor to drive a lead screw (threaded rod), and is provided with a clamping mechanism that can clamp different diameters. Although the prior art can basically meet the strength detection requirements of nylon threads, there are still deficiencies. For example, due to the different detection lengths of nylon threads, the moving position of the sliding plate needs to be frequently adjusted each time of detection; based on this situation, in order to ensure that the torque of the motor is sufficient, the forward and reverse motor set cannot use a high-speed motor, resulting in low detection efficiency; if a high-speed motor is used, it is difficult to control the moving speed of the sliding plate, and the sudden acceleration will cause an instantaneous impact on the nylon thread, affecting the final detection data. Therefore, there is a certain market demand for designing a detection device that can improve the detection efficiency and ensure the accuracy of detection data. Summary of the Invention
