Description

Technical Field

[0001] This invention relates to the field of fabric tensile property testing technology, and in particular to a device and method for testing the tensile properties of industrial sample fabrics. Background Technology

[0002] In industrial production, fabrics, as core raw materials for various products, directly determine the structural stability, service life, and safety reliability of end products due to their tensile properties, thus significantly impacting product quality across multiple industries, including textiles and apparel, industrial filter materials, tent fabrics, and automotive interiors. Therefore, tensile property testing of industrial fabric samples is a crucial step in raw material selection, production process quality control, and finished product acceptance. The accuracy and reliability of the test results are of great significance for improving enterprise production efficiency, controlling costs, and ensuring market competitiveness.

[0003] Currently, existing industrial fabric tensile property testing devices still have many shortcomings in practical applications, hindering the efficient conduct of testing and the improvement of testing accuracy: The clamping surface is prone to leaving debris, affecting testing consistency. During production, storage, and handling, fabric surfaces easily accumulate impurities such as lint and dust. Furthermore, rubber clamping pads, after contact and friction with the fabric, easily attract a large amount of fine debris due to electrostatic effects. Existing testing devices lack an automated cleaning mechanism linked to the clamping action, making it impossible to quickly remove residual debris between two sets of samples. This debris embeds into the contact surface of the rubber clamping pad, altering the actual friction coefficient and contact state of the clamping surface. This leads to uneven force distribution and fluctuations in clamping stability during subsequent sample clamping, resulting in inconsistent initial testing conditions for multiple sets of samples. Consequently, the repeatability and comparability of the test data deteriorate, making it difficult to form accurate and reliable quality analysis data. Summary of the Invention

During the interval between two sets of sample testing, the start switch can be triggered by adjusting the pressure plate with the torsion handle, which will automatically start the motor and drive the ion air bar to move smoothly along the guide rod. The ion air will perform all-round ion air cleaning on the surface of the rubber clamping pad. The ion air can effectively remove lint, dust and other debris adsorbed by static electricity in the clamping area, avoiding residual debris that may cause subsequent fabric clamping to be insecure or uneven in force. It not only saves the tedious steps of manual cleaning and saves testing time, but also ensures the consistency of testing conditions for multiple sets of samples, and improves the reliability and repeatability of the test results.

[0015] The device of this invention features a compact overall structure at the clamping end. The L-shaped front and rear mating plates not only provide a stable mounting base for components such as the ball screw and guide rod, but also provide ample space for the movement of the ion air bar through the empty area. The sliding engagement between the guide rod and the limiting sliding hole ensures that the movement of the ion air bar is smooth and precise, avoiding deviation that could affect the cleaning effect. At the same time, the torsion handle allows operators to easily clamp and release the fabric. The linkage control of the start switch, proximity switch, and control box enables automated start and stop of the cleaning process without complex manual intervention, reducing operational difficulty and improving overall detection efficiency.

[0016] The device of this invention achieves stable tensile force application by driving the clamping end with an electric cylinder. The extension and retraction speed of the electric cylinder's push rod can be precisely adjusted through the control box to meet the testing requirements of different sample fabrics for tensile loading rate. The tensile sensor collects tensile data in real time during the testing process and transmits it synchronously to the control box for recording and display. It can completely capture the stress changes of the fabric from the moment it is subjected to force to the moment it breaks (or reaches the preset tensile value), providing comprehensive data support for analyzing the tensile properties of the fabric. It is suitable for batch testing and quality control of the tensile properties of fabrics in industrial production. Attached Figure Description

The tension sensors 102 are fixedly connected to the left end of the clamping block 2 in the set of clamping ends; an electric cylinder 103 is fixedly installed on the right end of the detection table 1. The electric cylinder 103 is electrically connected to the control box; the push rod end of the electric cylinder 103 passes through the detection groove 101, and a set of clamping ends is fixedly installed on the push rod end. The left end of the clamping block 2 in the clamping end is fixedly connected to the push rod end of the electric cylinder 103.

[0024] The working principle of this embodiment: In the initial state, the top surface of the pressure plate 205 is not in contact with the button end of the start switch 2017, and the start switch 2017 is in the untriggered state. During the tensile performance test of the sample fabric, the push rod end of the electric cylinder 103 is extended by the control box to keep it in a fully extended state. The operator places both ends of the industrial sample fabric to be tested into the clamping grooves 203 of the two sets of clamping ends respectively, ensuring that the fabric is flat and in close contact with the rubber clamping pads 204 in the clamping grooves 203. Then, the torsion handle 209 is turned to drive the locking screw 208 to screw downward along the threaded through hole 2010. The locking screw 208 converts its rotational motion into linear motion through the rotating block 206 and the bearing 207, thereby pushing the pressure plate 205 to move downward synchronously until the rubber clamping pads 204 on the bottom surface of the pressure plate 205 are in close contact with the fabric, and the fabric is firmly clamped between the pressure plate 205 and the bottom surface of the clamping groove 203. During tensile performance testing, the control box controls the push rod end of the electric cylinder 103 to slowly retract. The push rod of the electric cylinder 103 drives a set of clamping ends connected to it to move to the right. The other set of clamping ends remains stationary under the fixing action of the tension sensor 102, thereby applying a horizontal tensile force to the sample fabric between the two sets of clamping ends. During the tensile force application, the tension sensor 102 detects the tensile force value borne by the fabric in real time and transmits the data synchronously to the control box for recording and display. As the push rod end of the electric cylinder 103 continues to retract, the tensile force gradually increases until the fabric reaches the tensile limit and breaks, or the preset tensile force value is detected. The tension sensor 102 records the maximum tensile force value and related force data, thereby achieving accurate detection of the tensile performance of the sample fabric. After completing the tensile performance test of a set of sample fabrics, before testing the tensile performance of the next set of sample fabrics, rotate the torsion handle 209 to drive the locking screw 208 to rotate upward along the threaded through hole 2010 until the top surface of the pressure plate 205 is in contact with the top surface of the inner end of the clamping groove 203. At this time, the start switch 2017 is in the pressed start state. After receiving the trigger signal from the start switch 2017, the control box synchronously starts the motor 2013, the ion air bar 2018, and the proximity switch b2022. Once the motor 2013 starts, its shaft drives the screw of the ball screw 2012 to rotate. Since the nut of the ball screw 2012 is fixedly installed in the mounting hole 2019 of the moving block 2014, and the moving block 2014 slides with the guide rod 2011 through the limiting sliding hole 2020, the screw rotation is converted into the horizontal movement of the moving block 2014 along the guide rod 2011 and the ball screw 2012. This, in turn, drives the ion air bar 2018 to move closer to the front mating plate 202. When the ion air bar 2018 is working, it releases ion air to clean the empty area between the two rubber clamping pads 204, i.e., the fabric clamping area, removing lint, dust, and other debris adsorbed by static electricity from the surface of the rubber clamping pads 204, thus preventing residual debris from affecting subsequent processes. The stability and detection accuracy of fabric clamping; when the ion air bar 2018 moves to the empty area between the front mating plate 202 and the clamping block 2, the sensing mating block 2015 on the moving block 2014 enters the sensing range of the proximity switch b2022. The proximity switch b2022 sends a signal to the control box, which then controls the motor 2013 to reverse and activates the proximity switch a2021. The reverse rotation of the motor 2013 drives the ball screw 2012 to rotate in the opposite direction, and the moving block 2014 returns along the original path until the ion air bar 2018 returns to the initial position between the rear mating plate 201 and the clamping block 2. At this time, the sensing mating block 2015 enters the sensing range of the proximity switch a2021, which sends a signal to the control box. The control box shuts down the motor 2013, the ion air bar 2018, the proximity switch a2021, and the proximity switch b2022, and the cleaning process is completed. After the cleaning process is completed, turn the torsion handle 209 to drive the locking screw 208 to screw downward along the threaded through hole 2010. The top surface of the pressure plate 205 will disengage from the button end of the start switch 2017, and the start switch 2017 will be in an untriggered state so that the next set of sample fabrics can be tested.
