Technical Field
[0001] This invention relates to the field of solid material strength and mechanical stress testing technology, specifically to a comprehensive testing device for the strength, elongation, and elasticity of nylon-covered yarn. Background Technology
[0002] Nylon-covered yarn is a composite yarn formed by wrapping other fibers (such as spandex) around nylon filaments as the outer layer. This structure allows the yarn to combine the abrasion resistance and high strength of nylon with the properties of the wrapped fibers. For example, when spandex is wrapped in the middle, the yarn has good elasticity.
[0003] Existing comprehensive testing devices for the strength, elongation, and elasticity of nylon-covered yarn typically involve stretching a single section of nylon-covered yarn from both ends, and then calculating the strength, elongation, and elasticity values of the nylon-covered yarn based on the stretching data. The overall operation is relatively simple, and test data can be obtained quickly, resulting in high work efficiency.
[0004] However, the existing comprehensive testing device for the strength, elongation, and elasticity of nylon-covered yarn has the following shortcomings:
[0005] 1) Existing comprehensive testing devices for the strength, elongation and elasticity of nylon-covered yarn can only test the strength, elongation and elasticity of nylon-covered yarn under normal conditions. They cannot test the strength, elongation and elasticity data of nylon-covered yarn under different stress conditions, which affects the testing accuracy and makes it difficult to meet the actual use requirements.
[0006] 2) The existing comprehensive testing device for the strength, elongation and elasticity of nylon covered yarn can only test the strength, elongation and elasticity of nylon covered yarn at normal temperatures. It cannot test the strength, elongation and elasticity data of nylon covered yarn at high temperature, which leads to actual usage deviations in the data and affects the final test results.
[0007] 3) The existing comprehensive testing device for the strength, elongation and elasticity of nylon covered yarn lacks an effective limiting mechanism when stretching nylon covered yarn, which can easily cause the bidirectional tensile force to deviate, thus affecting the accuracy of the test data. The device has poor stability in actual use and can easily affect the overall work efficiency.
[0008] Therefore, we propose a comprehensive testing device for the strength, elongation, and elasticity of nylon-covered yarn to address the problems mentioned above. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] A lifting assembly is provided on the top of the workbench 1, and an outward force simulation mechanism 11 is fixedly connected to the bottom of the lifting assembly. A drive transmission assembly is provided on one side of the outward force simulation mechanism 11.
[0038] The top of the workbench 1 has multiple ventilation holes, and the bottom of the workbench 1 is equipped with a high temperature simulation mechanism 18, with the ventilation holes located directly above the high temperature simulation mechanism 18.
[0039] The outward force simulation mechanism 11 includes a U-shaped frame 1101. Two first guide rods 1102 are fixedly connected to the inner side of the U-shaped frame 1101. A first lead screw 1103 is provided on the inner side of the U-shaped frame 1101. Sliding blocks 1104 are provided on the outer walls of the first lead screw 1103 and the two first guide rods 1102.

A second lead screw 1107 is provided on the side opposite to the limit frame 1106. Two second guide rods 1108 are provided on the side opposite to the limit frame 1106. A pressure frame 1109 is provided on the outer side of the second lead screw 1107 and the two second guide rods 1108. The limit frame 1106 is located inside the pressure frame 1109. A first bevel gear 1110 is connected to the bottom of the second lead screw 1107. A second bevel gear 1111 is meshed with the outer wall of a bevel gear 1110. A connecting shaft 1112 is fixedly connected to the inner side of the second bevel gear 1111. One end of the connecting shaft 1112 is connected to the drive transmission component. Through the setting of the gripper cylinder 6 and the clamping plate 7, the two ends of the nylon covered yarn can be clamped and fixed, which facilitates the bidirectional tensile test of the nylon covered yarn. Through the setting of the anti-slip texture 8, the friction between the nylon covered yarn and the clamping plate 7 can be effectively increased, preventing the nylon covered yarn from falling off during the tensile test, thereby improving the stability of the device during use.

[0040] according to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the high-temperature simulation mechanism 18 includes a heating chamber 1801, which is located directly below the vent. The heating chamber 1801 contains multiple heating wires 1802, and a blower 1803 is fixedly installed at the bottom of the heating chamber 1801. A dustproof net 1804 is installed at the input end of the blower 1803. By setting up the high-temperature simulation mechanism 18, a high-temperature testing environment can be simulated when performing biaxial tensile testing on nylon covered yarn, thereby improving the environment required for testing, making the test data more comprehensive and detailed, further reducing the difficulty of testing, improving the accuracy of test data, and reducing the subsequent defective product output rate.
[0041] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, each sliding platform 5 has a support seat 9 symmetrically arranged at both ends, and the top of the workbench 1 is provided with two guide rails 10. Each pair of support seats 9 is slidably installed inside the corresponding guide rail 10. By setting the guide rails 10, they cooperate with the support seats 9, thereby limiting the tensile force during the biaxial tensile test of nylon covered yarn and preventing it from shifting position. This improves the stability of the device during use, reduces the difficulty of testing, and further improves the overall work efficiency.
[0042] according to Figure 2 , Figure 3 and Figure 4 As shown, each of the two support bases 9 has a target 17 fixedly installed on one side, and two displacement sensors 16 are fixedly installed on the top of the workbench 1. Each displacement sensor 16 is adapted to a corresponding target 17. By setting the displacement sensor 16 to cooperate with the target 17, the tensile displacement distance and the length of the rebound force can be detected when performing biaxial tensile testing of nylon covered yarn, thereby improving the completeness of the test data and greatly improving the accuracy of the test data.
[0043] according to Figure 1 , Figure 7 and Figure 8 As shown, an electrical control cabinet 21 is installed on one side of the heating chamber 1801. One end of the electrical control cabinet 21 is connected to a connecting cable 20, and the other end of the connecting cable 20 is connected to a temperature sensor 19. The input end of the temperature sensor 19 is inserted inside the heating chamber 1801. Through the setting of the temperature sensor 19, the heating temperature can be monitored in real time, and the feedback can be sent to the relevant modules in the electrical control cabinet 21 through the connecting cable 20. Through the setting of the electrical control cabinet 21, the heating temperature can be adjusted in real time, thereby reducing the difficulty of operating the device, saving labor and time costs, and improving the overall work efficiency.
[0044] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stretching assembly includes a fixed plate 2. A first servo cylinder 3 is fixedly installed on one side of the fixed plate 2. The output end of the first servo cylinder 3 moves through the fixed plate 2 and is connected to the force sensor 4. By setting the fixed plate 2, the two ends of the nylon covered yarn can be stretched, thereby performing tensile strength and elasticity tests on the nylon covered yarn, improving the test accuracy and reducing the difficulty of operation.
[0045] according to Figure 1 , Figure 5 and Figure 6As shown, the drive transmission assembly includes two fixed frames 12, both of which are fixedly installed on one side of the U-shaped frame 1101. Each fixed frame 12 has a pulley 13 inside. A servo motor 14 is installed on one side of each fixed frame 12. The output end of the servo motor 14 passes through the single fixed frame 12 and is connected to the single pulley 13. A connecting shaft is installed inside the single pulley 13. One end of the connecting shaft passes through the U-shaped frame 1101 and is connected to the first lead screw 1103. One end of the connecting shaft 1112 passes through the U-shaped frame 1101 and is connected to the other pulley 13. A transmission belt 15 is sleeved on the outside of the two pulleys 13. By setting up the drive transmission assembly, the outward force simulation mechanism 11 can be controlled to apply a lateral push or downward pressure force separately for the biaxial tensile test of nylon covered yarn. The overall operation process is simplified, the difficulty of using the device is reduced, and the test accuracy is improved.
[0046] according to Figure 1 and Figure 2 As shown, the lifting assembly includes four supports 22, which are fixedly installed at the four corners of the top of the workbench 1. A top plate 23 is fixedly installed on the top of the four supports 22. A second servo cylinder 24 is installed on the top of the top plate 23. The output end of the second servo cylinder 24 passes through the top plate 23 and is connected to the U-shaped frame 1101. By setting up the lifting assembly, the height of the outward force simulation mechanism 11 can be flexibly adjusted, which makes it easier for manual placement of the tested nylon-covered yarn on the device and reduces the difficulty of subsequent cleaning.
[0047] according to Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, each of the four corners of the bottom of the workbench 1 is fixedly equipped with a leg 25, and each leg 25 is provided with an anti-slip pad 26 at the bottom. Through the arrangement of the leg 25 and the anti-slip pad 26, the two work together to provide stable support for the workbench 1, while increasing the friction with the ground to prevent the device from shaking, thereby improving the stability of the device during use.
[0048] according to Figure 1 and Figure 2 As shown, a control display 27 is installed on the top of the workbench 1. The control display 27 is connected to the internal structure of the equipment through wires. By setting the control display 27, the test data can be displayed. At the same time, by integrating various modules, the internal equipment of the device can be controlled and adjusted, thereby improving the intelligence level of the device, reducing the difficulty of manual operation, and improving the overall work efficiency.
[0049] Working principle: First, move the device to the working area and connect the lines to the internal equipment of the device in sequence to supply power to the device. Then, manually place the nylon covered yarn to be tested on the device and start the two gripper cylinders 6 to drive the corresponding clamping plates 7 to clamp the two ends of the nylon covered yarn to be tested.
[0050] During the tensile test, two first servo cylinders 3 are activated, driving the corresponding sliding platform 5 to slide under the limiting action of the gripper cylinder 6 and the guide rail 10. This causes the nylon-covered yarn, which is held by the gripper cylinder 6 and the clamping plate 7, to be stretched in two opposite directions. The tensile force generated by the stretching acts on the force sensor 4, and the force sensor 4 collects the tensile force data to preliminarily obtain the tensile strength and elasticity values of the nylon-covered yarn.
[0051] During the displacement detection stage, while the nylon-covered yarn is undergoing bidirectional tensile testing, the displacement sensor 16 is activated. The output end of the displacement sensor 16 emits a laser, and the laser point is located on the target 17 opposite to it. Based on the synchronous sliding of the target 17 with the gripper cylinder 6, the tensile length and elasticity data of the nylon-covered yarn will be collected and recorded by the displacement sensor 16, thereby obtaining accurate tensile length data and the breaking time point of the nylon-covered yarn.
[0052] During the outward force application stage, when the nylon-covered yarn undergoes biaxial tensile testing, the second servo cylinder 24 is activated to push the outward force simulation mechanism 11 down to the top of the worktable 1. Then, the servo motor 14 is activated to drive one pulley 13 and its connected first lead screw 1103 to rotate forward. Simultaneously, the transmission belt 15 drives another pulley 13 to rotate forward. The forward rotation force drives the connecting shaft 1112 and the second bevel gear 1111 to rotate. At this time, the first bevel gear 1110 drives the second lead screw 1107 to rotate synchronously. The sliding block 1104 then slides on the first guide rod 1102 and the first lead screw 1103. The pressure frame 1109 slides upward along the second lead screw 1107 and the second guide rod 1108, thereby applying a lateral thrust to the nylon-covered yarn and testing the nylon-covered yarn under lateral compression. Simultaneously, the tensile elasticity data during stretching is obtained, or the servo motor 14 is started to drive one pulley 13 and the first lead screw 1103 connected to it to reverse, and the transmission belt 15 drives another pulley 13 to reverse synchronously. The reversing force drives the connecting shaft 1112 and the second bevel gear 1111 to rotate. At this time, the first bevel gear 1110 drives the second lead screw 1107 to rotate synchronously. Then the sliding block 1104 slides away from the nylon-covered yarn on the first guide rod 1102 and the first lead screw 1103, while the pressure frame 1109 slides down along the second lead screw 1107 and the second guide rod 1108 to apply downward pressure to the nylon-covered yarn. The tensile elasticity data of the nylon-covered yarn when it is stretched while being pressed down is tested, thereby testing the tensile elasticity values of the nylon-covered yarn under different conditions.
[0053] During the high-temperature testing phase, the circuit is connected to the heating wire 1802 to begin heating the air. The temperature sensor 19 monitors the air temperature changes in real time and transmits these temperature values via the connecting cable 20 to relevant modules inside the electrical control cabinet 21. These modules perform detailed analysis and processing of the received temperature values. Based on the analysis results, the control module adjusts the heating power of the heating wire 1802 to ensure that the temperature inside the heating chamber 1801 gradually rises to the required level. Simultaneously, the blower 1803 is activated, blowing the heated high-temperature air through the vents onto the nylon-covered yarn. This is done to simulate the effect of a high-temperature environment during the biaxial tensile testing of the nylon-covered yarn. In this way, the tensile strength, elongation, elasticity, and related mechanical properties of the nylon-covered yarn under high-temperature conditions can be effectively tested.
[0054] During the data collection phase, all data generated during the test will be transmitted via wires to the control display 27 for real-time display and recording. Subsequently, this data will be collected and organized for further analysis and processing. In this process, the operator will substitute this data into the corresponding formulas, and through precise calculation and derivation, finally obtain the strength, elongation, and elasticity data of the nylon-covered yarn, ensuring the accuracy and reliability of the data.
[0055] By following the instructions above, you can complete the use of the comprehensive testing device for the strength, elongation, and elasticity of nylon-covered yarn.
