Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile tensile strength testing, and particularly relates to a textile tensile strength testing device. BACKGROUND

[0002] In the textile industry, the tensile strength of a textile is one of the key indicators of its quality and performance. This indicator is crucial for evaluating the durability and reliability of the textile in actual use. For example, in the clothing manufacturing industry, if the tensile strength of the textile is insufficient, the finished garment is prone to tearing, damage, and other problems during wear, affecting the service life and wearing experience of the garment. In the industrial field, textiles used to manufacture ropes, canvas, and other products have even more stringent requirements for tensile strength. If the strength is not up to standard, it may lead to serious safety accidents. However, the existing textile tensile strength testing equipment cannot monitor the clamping state of the textile in real time and provide a loose warning, so that when the textile is slightly loose during the tensile test, the operator cannot be notified in a timely manner, leading to problems such as distorted test data or textile falling off due to clamping failure.

[0019] The working principle of the embodiment is as follows: The two ends of the new material textile to be tested are respectively placed into the main clamping opening 2012 and the auxiliary clamping opening 205 of the two sets of clamping assemblies, and the textile is ensured to be flat and wrinkle-free, so as to avoid affecting the test accuracy due to the deviation of the clamping position. The specific clamping operation is as follows: First, manually rotate the main knob 209, rotate the main stud driving part 2025 along the main threaded driving through hole 2021, and convert the rotary motion into linear motion based on the main bearing 2023, so as to drive the main pressing plate 2013 to move downward along the main clamping opening 2012 until the textile is pressed tightly. Then, rotate the auxiliary knob 208, rotate the auxiliary stud driving part 2019 along the auxiliary threaded driving through hole 2015, and convert the rotary motion into linear motion based on the auxiliary bearing 2017, so as to drive the auxiliary pressing plate 206 to move downward along the auxiliary clamping opening 205 until the textile is pressed tightly. Start the driving motor 103 through the control box 104, and the motor shaft drives the two sets of connected ball screws 106 to rotate synchronously. Since the nuts of the two sets of ball screws 106 are respectively fixed in the mounting hole positions 2011 of the two sets of clamping assemblies, the rotation of the screws will be converted into the linear motion of the nuts, so as to drive the two sets of clamping assemblies to move in opposite directions along the limiting rods 105 and the moving sliding grooves 102, thereby exerting a stretching force on the new material textile in the middle. During the stretching process, the limiting insertion hole 203 of the clamping main block 2 is in sliding fit with the limiting rod 105 of the base 1, and the moving sliding block 204 slides along the moving sliding groove 102, so as to ensure that the two sets of clamping assemblies only stably move in the horizontal direction, avoid transverse deviation, and ensure that the stretching force direction is consistent with the axis of the textile. When the textile is subjected to tension, the two sets of clamping assemblies act on the bidirectional tension sensor 108 through the connecting belt 107. The sensor converts the tension data into an electrical signal in real time and transmits it to the control box 104, so as to realize dynamic monitoring and recording of the stretching force, and accurately capture the stress changes of the new material textile at different stretching stages. The displacement sensor 2010 at the bottom of the clamping main block 2 moves with the clamping assembly, and monitors the relative displacement of the two sets of clamping assemblies, i.e., the stretching length of the textile, and transmits the displacement data to the control box 104, which is synchronously associated with the tension data, thereby providing basic parameters for subsequent calculation of the tensile strength tension / texile cross-sectional area. When the stretching force borne by the new material textile reaches its ultimate tensile strength, the textile breaks, at which time the tension value monitored by the bidirectional tension sensor 108 suddenly drops, and the control box 104 automatically stops the driving motor 103 after recognizing the signal, thereby completing the test. Finally, the control box 104 processes the collected maximum tension value, corresponding displacement value and other data, calculates the tensile strength of the new material textile, and can output a test report through a matching system. Further, if the clamping main block 2 appears loose during the stretching process, the clamping auxiliary block 201 will move to the clamping main block 2 direction, so that the rubber pressing column 2016 approaches the pressure sensor 2022 and generates pressing, and after the pressure sensor 2022 senses the pressing force, it immediately sends a signal to the control box 104, the control box 104 triggers the flashing prompt light 202 on the front and rear end faces of the clamping main block 2, reminding the operator to stop the machine in time and check the clamping state, so as to avoid the test data distortion or the textile fabric falling off caused by clamping failure.
