Description

Technical Field

[0001] The invention relates to the field of cloth detection, and in particular to a textile cloth tensile strength detection device. Background Art

[0002] The textile fabric tensile testing device is mainly used to evaluate the stretchability and durability of textiles under stress, ensuring the comfort and performance of the fabric during use.

[0003] However, in actual use, the existing textile fabric stretch resistance detection device only uses vision to place, align and clamp the textile fabric, resulting in low positioning accuracy of the textile fabric and large errors in the measured textile fabric performance. In addition, some textile fabrics are also used in humid or water-immersed environments. Therefore, when measuring the performance of textile fabrics, it is also necessary to ensure that the textile fabric is moist. The existing technology only uses absorbent paper to absorb the soaked textile fabric. Since a single textile fabric needs to be tested multiple times, the moist textile fabric will be affected by various factors during the multiple tests, resulting in the humidity of the moist textile fabric cannot be guaranteed to be consistent during the multiple tests. The existing textile fabric stretch resistance detection device can only stretch flat textile fabrics, but cannot detect twisted textile fabrics, resulting in poor reference of stretch resistance test data for textile fabrics with high strength requirements.

[0028] A water storage box 29 is also included.

The water storage box 29 is used to recover excess water from the wet textile fabric.

[0029] It also includes a rotating shell 33, which is mirror-distributed between the upper clamping base 8 and the lower clamping base 24, and the top and bottom of the rotating shell 33 are both rotatably connected with a sliding rod 32, and the outer wall of the sliding rod 32 is slidably connected with an articulated sleeve 31, which is used to limit the rotation angle of the lower clamping base 24 to prevent overlapping interference with the stretching test result when the textile fabric is twisted.

[0030] It also includes a second bevel gear set 34, an atomizing nozzle 35 and an electric water pump 37. The second bevel gear set 34 is installed in the rotating shell 33. The second bevel gear set 34 includes a second active bevel gear, a third active bevel gear and a second driven bevel gear meshing with the second active bevel gear and the third active bevel gear are respectively fixed to the upper and lower sliding rods 32.

The electric water pump 37 is fixedly installed in a mirror-image distribution at the bottom of the water storage box 29. The electric water pump 37 is connected to the atomizing nozzle 35 through a hose.

[0031] The staff first needs to cut the textile fabric into long strips, and straighten the short side of the textile fabric upwards, with one side of the short side of the textile fabric attached to the front side of the elastic clamping plate 13. Then the staff moves the textile fabric upwards along the elastic clamping plate 13, so that the short side of the top of the textile fabric is in contact and aligned with the bottom of the upper clamping base 8. It is worth noting that the elastic clamping plate 13 is initially in a bent state, so that one side of the short side of the top of the textile fabric maintains the same arc shape as the elastic clamping plate 13. The textile fabric in an arc state has a stronger bending resistance than the textile fabric in a parallel state, so that when the top of the textile fabric is aligned with the bottom of the upper clamping base 8, it will not bend. Since the textile fabric is in an arc state, its two corners are easily moved. The textile fabric bends and deforms in the direction of the overall arc bending, so the elastic clamping plate 13 is used to support the arc bending direction of the textile fabric to prevent its two corners from bending and deforming, and the textile fabric's own horizontal tensile strength is used to resist bending and deforming the two corners of the textile fabric in the direction away from the elastic clamping plate 13, so that the top of the textile fabric keeps its shape unchanged. Therefore, even if there is no staff pressing on the top of the textile fabric, the shape of its own top can be ensured to fit the elastic clamping plate 13, which reduces the difficulty of staff fixing the textile fabric and avoids the problem of large errors in detection results when the textile fabric is clamped due to staff relying on visual alignment of the textile fabric, thereby improving the positioning accuracy of the textile fabric. The pressing frame 17 is pushed open, so that the pressing frame 17 drives the pressure pad 18 to rotate, and the pressure pad 18 is separated from the elastic clamping plate 13. At the same time, the pressing frame 17 rotates to deform the torsion spring. The staff puts the two corners of the short side of the textile fabric behind the pressure pad 18, and then releases the pressing frame 17. The torsion spring drives the pressing frame 17 to reset, thereby driving the pressure pad 18 to rotate and reset, so that the pressure pad 18 squeezes one end of the short side of the textile fabric. One end of the short side of the textile fabric is fixed on the elastic clamping plate 13, which further reduces the difficulty of the staff in fixing the textile fabric and realizes the preliminary fixation of the textile fabric. Then the staff rotates the first handle 15, and the first handle 15 rotates to drive the sliding push-pull frame 10 and the sliding clamping plate through the bidirectional screw rod 9. 14 are close to each other, and the sliding push-pull frame 10 drives the connecting frame 12 to move forward through the connecting rod 11 during the forward movement. The connecting frame 12 moves forward to restore the elastic clamping plate 13 to its shape. Since the short side of the textile fabric is always in contact with the front side of the elastic clamping plate 13, the elastic clamping plate 13 straightens the textile fabric again during the process of restoring its shape. It is worth noting that when the textile fabric is straightened again, the elastic clamping plate 13 also restores its straightness. At this time, the front end of the sliding push-pull frame 10 will contact the elastic clamping plate 13, and the sliding clamping plate 14 will contact and squeeze the textile fabric, so that the elastic clamping plate 13 and the sliding clamping plate 14 jointly clamp the textile fabric, thereby realizing the top positioning of the textile fabric when testing the tensile strength.

[0032] After the top short side of the textile fabric is positioned, the staff pulls the bottom short side of the textile fabric to the rear of the eccentric clamping rod 25, so that the textile fabric passes through the gap between the eccentric clamping rod 25 and the lower clamping base 24, and the textile fabric passes through the gap between the eccentric graphite shaft 27 and the lower clamping base 24, straightens the textile fabric between the upper clamping base 8 and the lower clamping base 24, and makes the cylindrical graphite shaft 20 contact the textile fabric, so that graphite marks can be left on the surface of the textile fabric, and the third handle 26 is rotated to make the third handle 26 drive the eccentric clamping rod 25 to rotate, and the eccentric clamping rod 25 clamps the textile fabric to achieve further positioning of the textile fabric. At the same time, the rotation of the eccentric clamping rod 25 drives the eccentric graphite shaft 27 to rotate synchronously through the crank drive group 28, and the eccentric graphite shaft 27 contacts and squeezes the textile fabric, so that graphite marks can be left on the surface of the textile fabric.

[0033] After completing the positioning of the textile fabric, the staff begins to test the tensile strength of the textile fabric and starts the motor 4. The output shaft of the motor 4 rotates to drive the one-way screw 5 to rotate synchronously, so that the one-way screw 5 drives the sliding support frame 6 to move upward along the light rod 2. The sliding support frame 6 moves upward and drives the upper clamping base 8 to rotate through the tension sensor 7. The upper clamping base 8 drives the elastic clamping plate 13 and the sliding clamping plate 14 to move upward through the bidirectional screw 9, thereby pulling the textile fabric to deform the textile fabric. If it is necessary to test the ultimate tensile strength of the textile fabric, the elastic clamping plate 13 and the sliding clamping plate 14 continue to move upward until the textile fabric breaks. If it is necessary to test the reciprocating tensile strength of the textile fabric After the elastic clamping plate 13 and the sliding clamping plate 14 move upward for a distance, the output shaft of the motor 4 rotates in the opposite direction and drives the one-way screw 5 to rotate synchronously, so that the one-way screw 5 drives the sliding support frame 6 to move downward along the light rod 2, and the sliding support frame 6 moves downward and drives the upper clamping base 8 to move synchronously through the tension sensor 7, and the upper clamping base 8 drives the elastic clamping plate 13 and the sliding clamping plate 14 to move downward through the bidirectional screw 9, so that the textile fabric recovers its shape, and the above-mentioned reciprocating movement of the elastic clamping plate 13 and the sliding clamping plate 14 is repeated to realize the measurement of the reciprocating tensile strength of the textile fabric. In the above-mentioned process of detecting the tensile strength of the textile fabric, when the textile fabric is clamped stably, The graphite trace left by the friction of the cylindrical graphite shaft 20 or the eccentric graphite shaft 27 on the surface of the textile fabric is a fixed value. If the clamping of the textile fabric is unstable, the graphite trace left by the friction of the cylindrical graphite shaft 20 or the eccentric graphite shaft 27 on the surface of the textile fabric will be longer. If the clamping of the elastic clamping plate 13 and the sliding clamping plate 14 is unstable, the top of the textile fabric will move downward along the elastic clamping plate 13 and the sliding clamping plate 14 when it is stretched. At this time, the cylindrical graphite shaft 20 will leave a longer graphite trace on the surface of the textile fabric. At the same time, if the clamping of the lower clamping base 24 and the eccentric clamping rod 25 is unstable, the bottom of the textile fabric will slide upward along the lower clamping base 24 and the eccentric clamping rod 25 when it is stretched. At this time, the eccentric graphite The shaft 27 will leave longer graphite marks on the surface of the textile fabric due to friction. After the experiment, the length of the graphite marks on the textile fabric is measured. If the length of the graphite marks exceeds the fixed value, it means that the clamping of the textile fabric is unstable, which leads to a large deviation in the test result of the textile fabric. It is necessary to re-execute the above-mentioned process of testing the tensile strength of the textile fabric. When the top of the textile fabric is clamped by the elastic clamping plate 13 and the sliding clamping plate 14, its top fails to align with the bottom of the upper clamping base 8. During the textile fabric stretching test, the cylindrical graphite shaft 20 will leave inclined or fan-shaped graphite marks on the surface of the textile fabric, indicating that the test result of the textile fabric stretching has a large deviation, and it is necessary to re-execute the above-mentioned process of testing the tensile strength of the textile fabric.

[0034] For the tensile testing of wet textile fabrics, the staff needs to soak the textile fabric in water for a period of time, and then wipe the surface of the textile fabric with absorbent paper. Since the moisture level of the textile fabric cannot be guaranteed to be stable, the staff positions the textile fabric through the above operations, injects water into the water storage box 29, and starts the electric water pump 36, so that the water in the water storage box 29 is pumped into the atomizing nozzle 32 through the hose by the electric water pump 36, and small particles of water mist are sprayed out through the atomizing nozzle 32. The sprayed small particles of water mist continue to act on the textile fabric, so that the moisture on the surface of the textile fabric increases. As the moisture on the surface of the textile fabric continues to evaporate, the speed of moisture increase on the surface of the textile fabric will gradually become equal to the speed of evaporation, thereby The humidity of the textile fabric remains stable as the small particles of water mist are continuously sprayed out. Then the staff performs the stretching test of the textile fabric. Since the humidity of the textile fabric is stable, under the premise of the standard stretching test of the textile fabric, the data results of the stretching of the textile fabric will be more stable and accurate. At the same time, since the surface of the lower clamping base 24 is rough and has high thermal conductivity, the small particles of water mist falling on the lower clamping base 24 will evaporate and take away the heat of the lower clamping base 24, making the lower clamping base 24 cooler, and then the subsequent water mist falling on the lower clamping base 24 will not continue to evaporate, but will gather into water droplets and flow back to the water storage box 29 along the inclined surface of the lower clamping base 24, so as to realize the recycling of water and avoid the waste of water resources.

[0035] During the stretching test of textile fabrics, for some textile fabrics, it is necessary to test the tensile strength of the textile fabrics when they are twisted. At this time, the staff can rotate the second handle 23. The rotation of the second handle 23 drives the lower clamping base 24 to rotate synchronously through the first bevel gear set 22. The rotation of the lower clamping base 24 drives the eccentric clamping rod 25 to rotate, and rotates the bottom end of the textile fabric clamped by the lower clamping base 24 and the eccentric clamping rod 25, so that the textile fabric is twisted. The textile fabric can be tested for its tensile strength in a twisted state, thereby realizing the tensile strength test of the textile fabric when it is twisted. In the process of rotation of the lower clamping base 24 (such as Fig. 9The second articulated frame 36 rotates synchronously with the articulated sleeve 31 at the bottom in the vertical direction. When the lower clamping base 24 rotates, the second articulated frame 36 and the articulated sleeve 31 below rotate in an inclined manner along the front-back direction and move in the left-right direction. The second articulated frame 36 at the bottom moves to the left to rotate itself, and at the same time, the two articulated sleeves 31 distributed above and below are always coaxial. The rotation of the second articulated frame 36 drives the articulated sleeve 31 below to rotate synchronously. The articulated sleeve 31 below drives the rotating shell 33 to rotate through the sliding rod 32 below, and then the upper articulated sleeve 31 rotates through the sliding rod 32 above, so that the two articulated sleeves 31 distributed above and below are always coaxial along the left-right direction. Similarly, the second articulated frame 36 moves in the front-back direction with the articulated sleeve 31 below. The hinge 31 is rotated to rotate itself, and at the same time, in order to make the two articulated sleeves 31 distributed above and below always coaxial, the second articulated frame 36 rotates to drive the lower articulated sleeve 31 to rotate synchronously, and the lower articulated sleeve 31 drives the rotating shell 33 to move through the lower sliding rod 32, and then the upper articulated sleeve 31 is rotated through the upper sliding rod 32, and the rotation of the articulated sleeve 31 causes the first articulated frame 30 to rotate synchronously, so that the two articulated sleeves 31 distributed above and below are always coaxial along the front-to-back direction. Since the two articulated sleeves 31 distributed above and below are coaxial along the left-right direction and the front-to-back direction, the two articulated sleeves 31 distributed above and below are located on the same axis, wherein the two articulated sleeves 31 located above will be staggered in space during the rotation process, and the two rotating shells 33 are The distance between the two hinged sleeves 31 and the hinged sleeve 33 will gradually become closer as the lower clamping base 24 rotates, and finally the two rotating shells 33 will contact each other, thereby limiting the rotation angle of the lower clamping base 24 to prevent the textile fabric from overlapping when it is twisted, which causes interference in the detection of the textile fabric's tensile strength. At the same time, the distance between the two hinged sleeves 31 distributed above and below will become longer as they rotate, causing the sliding rod 32 to slide in the hinged sleeve 31, and the spring is stretched. Since the elastic parts of the upper and lower parts are both springs, the sliding rods 32 of the upper and lower parts slide the same distance in the hinged sleeve 31. It is worth noting that the rotation of the lower clamping base 24 drives the hinged sleeve 31 below to rotate synchronously through the second hinged frame 36, and the rotation of the lower clamping base 24 in the vertical direction is in the second hinged frame. The rotation of the articulated frame 36 and the articulated sleeve 31 is converted into the axial rotation of the lower articulated sleeve 31. The axial rotation of the lower articulated sleeve 31 drives the lower sliding rod 32 to rotate synchronously. The rotation of the lower sliding rod 32 causes the third active bevel gear of the second bevel gear set 34 to rotate, and cooperates with the second active bevel gear to drive the second driven bevel gear to rotate, so that the second driven bevel gear rotates along the axial direction of the sliding rod 32. The second driven bevel gear rotates along the axial direction of the sliding rod 32 so that the rotating shell 33 drives the atomizing nozzle 35 to rotate synchronously. Since the upper clamping base 8 does not rotate in the vertical direction, the rotation angle of the third active bevel gear along the axial direction of the sliding rod 32 is half of the lower clamping base 24, so that the atomizing nozzle 35 is always facing the textile fabric.Ensure that the moisture level of the wet textile fabric is stable when the wet textile fabric is subjected to tensile testing, thereby making the tensile strength test results of the wet and twisted textile fabric more accurate.
