Description

Technical Field

[0001] The present invention relates to the technical field of mechanical stress testing of solid material strength, and particularly to a comprehensive testing device for the strength, elongation and elasticity of nylon covered yarns. Background Art

[0002] Nylon covered yarn is a composite yarn, which takes nylon filament as the outer wrapping fiber and wraps other fibers (such as spandex, etc.) in the middle to form a yarn. This structure enables the yarn to have both the characteristics of nylon such as wear resistance and high strength and the characteristics of the wrapped fibers. For example, when spandex is wrapped in the middle, the yarn has good elasticity.

[0003] When the existing comprehensive testing device for the strength, elongation and elasticity of nylon covered yarn is in use, it usually stretches from both ends of a single section of nylon covered yarn, and then calculates the strength, elongation and elasticity values of the nylon covered yarn according to the stretching data. The overall operation is relatively simple, and the test data can be obtained quickly, with high work efficiency.

[0004] However, the existing comprehensive testing device for the strength, elongation and elasticity of nylon covered yarn has the following deficiencies:

[0005] 1) 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 under normal conditions, and cannot test the strength, elongation and elasticity data of nylon covered yarn under different stress conditions, thus affecting the detection accuracy and making 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 temperature, and cannot test the strength, elongation and elasticity data of nylon covered yarn in a high-temperature environment, thus resulting in actual use deviation of the data and affecting the final test result.

[0007] 3) When the existing comprehensive testing device for the strength, elongation and elasticity of nylon covered yarn stretches the nylon covered yarn, it lacks an effective limiting mechanism, which easily causes the bi-directional tensile force to deviate, thus affecting the accuracy of the test data. The actual use stability is poor, and it is easy to affect the overall work efficiency.

[0008] Therefore, we propose a comprehensive testing device for the strength, elongation and elasticity of nylon covered yarn to solve the problems raised above. Summary of the Invention

[0048] according to Figure 1 and Figure 2 As shown, a control display 27 is arranged on the top of the workbench 1. The control display 27 is connected to the internal structure of the device through a wire. Through the setting of 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 turn to power the device, then manually place the nylon covered yarn to be tested on the device, and start the two clamping claw 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 phase, the two first servo cylinders 3 are started to drive the corresponding sliding platform 5 to slide under the limiting action of the clamping cylinder 6 and the guide rail 10, and the nylon coated yarn clamped by the clamping cylinder 6 and the clamping plate 7 is stretched in two opposite directions. The tension generated by the stretching acts on the force sensor 4, and the tension data is collected by the force sensor 4 to preliminarily obtain the strength and elongation elasticity values ​​of the nylon coated yarn.

[0051] During the displacement detection stage, while the nylon coated yarn is undergoing a biaxial tensile test, the displacement sensor 16 is started, and the output end of the displacement sensor 16 emits a laser, and the laser lands on a target mark 17 opposite to it. Based on the synchronous sliding of the target mark 17 following the gripper cylinder 6, the tensile length and elasticity data of the nylon coated yarn will be collected and recorded by the displacement sensor 16, thereby obtaining accurate tensile length data and the breaking time node of the nylon coated yarn.

[0052] During the outward force application stage, when the nylon coated yarn is subjected to a biaxial tensile test, the second servo cylinder 24 is started to push the outward force simulation mechanism 11 down to the top of the workbench 1, and then the servo motor 14 is started to drive a pulley 13 and a first screw rod 1103 connected thereto to rotate forward, and the transmission belt 15 drives another pulley 13 to rotate forward synchronously, and 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 screw rod 1107 to rotate synchronously, and the sliding block 1104 slides on the first guide rod 1102 and the first screw rod 1103, and the pressure frame 1109 slides upward along the second screw rod 1107 and the second guide rod 1108, thereby applying a lateral thrust to the nylon coated yarn to test the nylon coated yarn under lateral extrusion. The strength and elongation elastic data during simultaneous stretching, or the servo motor 14 is started to drive a pulley 13 and the first screw rod 1103 connected thereto to reverse, and the transmission belt 15 drives the other pulley 13 to reverse synchronously, and the reversal 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 screw rod 1107 to rotate synchronously, and the sliding block 1104 slides on the first guide rod 1102 and the first screw rod 1103 away from the nylon coated yarn, and the pressure frame 1109 slides downward along the second screw rod 1107 and the second guide rod 1108, exerting downward pressure on the nylon coated yarn, and testing the strength and elongation elastic data of the nylon coated yarn when being pressed down and stretched at the same time, so as to test the strength and elongation elastic values ​​of the nylon coated yarn under different states.

[0053] During the high temperature test phase, the circuit is connected to the heating wire 1802 to start heating the air. The temperature sensor 19 will monitor the changes in air temperature in real time, and transmit these temperature values ​​to the relevant modules inside the electrical control cabinet 21 through the connecting cable 20. These modules will perform detailed analysis and processing on the received temperature values. According to the analysis results, the control module will adjust the heating power of the heating wire 1802 to ensure that the temperature in the heating chamber 1801 gradually rises to the required level. At the same time, the blower 1803 is started to blow the heated high-temperature air through the air vent to the nylon coated yarn. The purpose of this is to simulate the effect of a high temperature environment when the nylon coated yarn is subjected to a biaxial tensile test. In this way, the strength, elongation, elasticity and related mechanical properties of the nylon coated yarn under a high temperature environment can be effectively tested.

[0054] In the data collection stage, various data generated during the test will be transmitted to the control display 27 through wires for real-time display and recording. Subsequently, these data will be collected and sorted for further analysis and processing. In this process, the manual operator will substitute these data into the corresponding formula, and finally obtain the strength, elongation and elasticity data of the nylon coated yarn through precise calculation and deduction to ensure the accuracy and reliability of the data.

[0055] According to the above-mentioned operations, the use of the nylon coated yarn strength, elongation and elasticity comprehensive testing device can be completed.
