[0017] Working principle: after the production of nylon elastic yarn is completed, some samples need to be tested. When testing the samples, the staff can use the equipment to test multiple or single strand samples. The staff places the sample on the test bench 1, and starts the hydraulic cylinder 7 through the main console to start working. The hydraulic cylinder 7 drives the pressure plate 8 to press down to perform a pressure test on the sample. Before the test, the staff can put the sample on the movable plate 31. After it is placed, the movable plate 31 is driven to move by starting the cylinder 2. The movement of the movable plate 31 drives the telescopic rod 32 to move. The movement of the telescopic rod 32 drives the splint 33 to move. The movement of the splint 33 drives the pulley 34 to move. The pulley 34 moves through the circumferential surface and contacts the inner wall of the guide plate 35 to drive the pulley 34 to move downward.

At the same time, the sample can be guided by the elastic clamping of roller 1 38 and roller 2 39 to prevent deviation during loading, which causes the nylon elastic thread to bounce open due to excessive tension, greatly improving the reliability and comparability of the test results, and facilitating the accurate evaluation and comparison of the quality of nylon stretch thread.

[0018] Before pulling the test sample, the clamping plate 33 moves downward and drives the L-shaped rod 41 to move downward, so that the L-shaped rod 41 moves to the bottom and contacts the circumferential surface of the rotating wheel 44. When the cylinder 2 drives the clamping plate 33 to move to both sides, the L-shaped rod 41 drives the rotating wheel 44 to rotate through the contact surface at the bottom, and the rotating wheel 44 drives the threaded rod 42 to rotate. The threaded rod 42 drives the paddle plate 43 to move through the threaded groove on the circumferential surface to paddle the sample, thereby avoiding local stress concentration and dispersing the tension to the entire wire cross section, so that the tension can be more evenly borne, thereby more accurately reflecting the overall tensile properties of the sample and improving the testing efficiency of the equipment. When the sample is pressure tested, the pressure plate 8 moves to drive the inclined block 45 to move, and the inclined block 45 moves through the inclined surface to drive the inclined plate 48 to move, and the inclined plate 48 moves to drive the moving column 47 to guide the sample to prevent the sample from shifting during the test, thereby improving the repeatability and accuracy of the test results, and by controlling the deformation and movement direction of the sample, the service life of the testing equipment can be extended and the equipment maintenance cost can be reduced.

Step 3: At the same time, the cylinder 2 drives the clamping plate 33 to move to both sides, and the clamping plate 33 drives the sample to pull the cotton nylon yarn to tighten, so as to prevent the sample from detaching during the test and causing the test failure; Step 4: The sample can be pre-clamped by passing between roller one 38 and roller two 39, which facilitates the loading of the sample and prevents the silk thread from impacting the pressure sensor due to sudden tension changes. At the same time, the sample can be guided by the elastic clamping of roller one 38 and roller two 39 to prevent deviation during loading, which causes the nylon elastic line to bounce off due to excessive tension.

7. The finished product inspection machine for nylon stretch yarn processing according to claim 6 is characterized by: The auxiliary mechanism (5) comprises a second inclined block (51), a sliding plate (52), an extrusion block (53), an elastic rod (54), a connecting plate (55), a connecting rod (56), a positioning block (57), and a protective shell (58). The second inclined block (51) is fixedly connected to the outer surface of the moving column (47), the sliding plate (52) is slidably connected to the inner wall of the test bench (1) via a spring, the extrusion block (53) is fixedly connected to the outer surface of the sliding plate (52), the elastic rod (54) is fixedly connected to the top of the sliding plate (52), the connecting plate (55) is fixedly connected to the top of the elastic rod (54), the connecting rod (56) is hinged to the outer surface of the moving column (47), the positioning block (57) is fixedly connected to the top of the test bench (1), and the protective shell (58) is rotatably connected to the inner wall of the positioning block (57) via a torsion spring.

8. The finished product inspection machine for nylon stretch yarn processing according to claim 7 is characterized by: The side of the connecting rod (56) away from the moving column (47) is hinged to the protective shell (58), and the moving track of the second inclined block (51) is in contact with the extrusion block (53).

9. A method for detecting a finished product of nylon stretch yarn by a testing machine, using the finished product of nylon stretch yarn testing machine according to claim 8, characterized in that: The following steps are involved: Step 1: The staff places the sample on the test bench (1), and starts the hydraulic cylinder (7) through the main console to start working. The hydraulic cylinder (7) drives the pressure plate (8) to press down to perform a pressure test on the sample; Step 2: Before the test, the staff can place the sample on the movable plate (31). After the sample is placed, the cylinder (2) is started to drive the movable plate (31) to move. The movement of the movable plate (31) drives the telescopic rod (32) to move. The movement of the telescopic rod (32) drives the clamping plate (33) to move. The movement of the clamping plate (33) drives the pulley (34) to move. The pulley (34) moves through the circumferential surface and contacts the inner wall of the guide plate (35) to drive the pulley (34) to move downward. The downward movement of the pulley (34) drives the clamping plate (33) to move downward to clamp the single-strand or multi-strand sample. Step 3: At the same time, the cylinder (2) drives the clamping plate (33) to move to both sides, and the clamping plate (33) drives the sample to pull to both sides to tighten the nylon yarn, so as to prevent the sample from being separated during the test and causing the test failure; Step 4: The sample can be pre-clamped by passing between roller one (38) and roller two (39), which facilitates the loading of the sample and prevents the silk thread from impacting the pressure sensor due to sudden tension changes. At the same time, the elastic clamping of roller one (38) and roller two (39) can guide the sample to prevent the sample from being offset during loading, which may cause the nylon elastic thread to bounce off due to excessive tension.
