Description

Technical Field

[0001] This invention belongs to the field of textile testing technology, specifically a tensile testing device for textile fabrics. Background Technology

[0002] Textile fabrics, also known as knitted fabrics, can be divided into two categories according to their weaving methods: weft-knitted fabrics and warp-knitted fabrics. Weft-knitted fabrics are often made from low-elastic polyester yarn or profiled polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., and are woven on various weft knitting machines using plain knitting, modified plain knitting, rib plain knitting, double rib plain knitting, jacquard, terry knitting, etc.

[0003] A patent with publication number CN118443458B discloses a tensile testing device and method for textile fabrics. The key technical features include a platform with four symmetrically arranged uprights fixedly connected to its upper side. Two horizontal supports are fixedly connected to the upper ends of the uprights on the same side, and the two horizontal supports are symmetrically distributed. This invention discloses a tensile testing device and method for textile fabrics. When performing tensile testing, the tensile testing component converts the lateral tension applied to both ends of the textile fabric during the testing process into a longitudinal force. The magnitude of the applied force is controlled by changing the moving distance of the shifting frame, thereby achieving precise control and avoiding the problem of inaccurate force control that occurs when force is applied directly to both ends of the textile fabric.

[0004] However, the above-mentioned technologies often have the following drawbacks: during the tensile testing process, the lateral tension applied to both ends of the textile fabric can be converted into a longitudinal force state, but it is not possible to perform local tensile testing on the middle part of the textile fabric. It can only stretch the two ends of the textile fabric, which limits the accuracy of the test results.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention discloses a tensile testing device for textile fabrics, which fixes the textile fabric between two sets of lower clamping plates and two sets of upper clamping plates, and passes the textile fabric through the winding assembly. The first guide rail and the second drive motor in the testing assembly cooperate to drive the first drive gear and the second drive motor to rotate on the first rack and the second drive rack, thereby driving the testing frame and the vertical rod to move.

This allows for stretching of different positions of the textile fabric, and the stretching force and speed can be adjusted according to actual needs to meet the testing requirements of different textile fabrics.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 10As shown in the embodiment of the present invention, a tensile testing device for textile fabrics includes a machine frame 1. Two sets of support columns 3 are fixedly installed on the upper sides of both the left and right ends of the machine frame 1. Lower clamping plates 4 are symmetrically installed on the upper ends of the four sets of support columns 3 installed on the left and right ends of the machine frame 1. Upper clamping plates 5 are movably installed on both sets of lower clamping plates 4. Locking bolts 6 are provided at the contact points between the upper clamping plates 5 and the lower clamping plates 4 at both ends of the two sets of upper clamping plates 5. An adjustment component is provided on the upper side of the machine frame 1. A detection component is provided on the adjustment component. A tensile component is provided on the upper side of the adjustment component.

[0035] The textile fabric is fixed between two sets of lower clamping plates 4 and two sets of upper clamping plates 5, and the textile fabric passes through the stretching components. The stretching components and the detection components are moved by the adjustment components. The stretching components stretch different positions of the fixed textile fabric, and the detection components detect the stretched textile fabric inside the machine box, thereby improving the accuracy and practicality of the stretch detection of the textile fabric.

[0036] like Figures 1 to 8 As shown, the upper side of the lower clamping plate 4, symmetrical to the upper clamping plate 5, and the lower surface of the upper clamping plate 5 are both provided with serrated teeth. The surfaces of the serrated teeth on the upper side of the lower clamping plate 4, symmetrical to the upper clamping plate 5, and the lower surface of the upper clamping plate 5 are all covered with rubber material.

[0037] By setting serrated teeth, the friction between the lower clamping plate 4 and the upper clamping plate 5 is increased, which allows the textile fabric to be clamped more stably. At the same time, the rubber wrapping can protect the textile fabric from being pinched and damaged, thus improving the practicality and safety of the device.

[0038] like Figures 1 to 2 As shown, the adjustment assembly includes a third drive motor 24, which is fixedly installed on the right side of the equipment frame 1. An adjustment screw 25 is rotatably installed inside the equipment frame 1. The adjustment screw 25 is fixedly connected to the output shaft of the third drive motor 24. Second guide rails 26 are symmetrically installed on the upper side of the equipment frame 1. Two sets of slide blocks 27 are threaded onto the adjustment screw 25. The lower sides of the two sets of slide blocks 27 are slidably connected to the two sets of second guide rails 26. An installation platform 28 is fixedly installed on the upper side of the two sets of slide blocks 27.

[0039] The third drive motor 24 drives the adjusting screw 25 to rotate. Since the adjusting screw 25 is fixedly connected to the output shaft of the third drive motor 24, the rotation of the adjusting screw 25 will drive the slide block 27 to slide on the second guide rail 26, thereby realizing the left and right movement of the mounting platform 28, which in turn drives the stretching component and the detection component to move synchronously, so as to detect different positions of the textile fabric, improving the flexibility and practicality of the device.

[0040] like Figures 3 to 9 As shown, the detection assembly includes two sets of mounting brackets 2 and a crossbeam 7. The two sets of mounting brackets 2 are fixedly installed on the front and rear sides of the mounting platform 28. The crossbeam 7 is fixedly installed on the upper end of the two sets of mounting brackets 2. A first rack 8 is fixedly installed on the upper side of the crossbeam 7. A first guide rail 9 is fixedly installed on the left side of the crossbeam 7. A detection frame 10 is slidably installed on the first guide rail 9. A first drive motor 11 is fixedly installed on the upper end of the detection frame 10. A first drive gear 12 is fixedly installed on the output shaft of the first drive motor 11. The first drive gear 12 meshes with the left side of the first rack 8. The left side of the detection frame 10... A vertical rod 13 is slidably mounted. A second drive rack 14 is fixedly mounted on the front side of the vertical rod 13. A second drive motor 15 is fixedly mounted on the front side of the detection frame 10. A second drive gear 16 is fixedly mounted on the output shaft of the second drive motor 15. The second drive gear 16 meshes with the right side of the second drive rack 14. A base plate 17 is fixedly mounted on the lower side of the vertical rod 13. A reinforcing frame 18 is fixedly mounted on the upper side of both the front and rear ends of the base plate 17. An auxiliary fixing component 19 is fixedly mounted on the upper end of the reinforcing frame 18. A detection probe 20 is fixedly mounted on the left side of the reinforcing frame 18 and the auxiliary fixing component 19.

[0041] The output shaft of the first drive motor 11 rotates, driving the first drive gear 12 to rotate on the first rack 8, which in turn drives the detection frame 10 to slide back and forth on the crossbeam 7 and the first guide rail 9. At the same time, the output shaft of the second drive motor 15 drives the second drive gear 16 to rotate on the second drive rack 14, which in turn drives the vertical rod 13 and the second drive rack 14 to slide up and down on the detection frame 10. As the vertical rod 13 and the second drive rack 14 slide up and down, the reinforcing frame 18 moves synchronously. Then, through the movement of the detection frame 10, the vertical rod 13 and the reinforcing frame 18, the detection probe 20 is brought close to the part of the textile fabric to be tested. The detection probe 20 is used to test the textile fabric, and it can capture in real time the minute changes of the textile fabric during the stretching process, such as deformation, stress distribution and other key parameters.

[0042] like Figures 1 to 4 As shown, a lighting bracket 21 is fixedly installed on the lower left side of the reinforcing frame 18. Lighting mounting bases 22 are symmetrically installed on the rear side of the lighting bracket 21. Detection lights 23 are provided on the rear side of both lighting mounting bases 22. The two sets of detection lights 23 are located on the front and rear sides of the lower end of the detection probe 20.

[0043] The detection lighting 23 allows for localized illumination of the detection area, facilitating the observation and analysis of subtle changes in the textile fabric during the stretching process. This also enables clearer and more accurate detection of the textile fabric by the detection probe 20.

[0044] like Figures 5 to 10As shown, the tensioning assembly includes four sets of columns 29, which are fixedly installed at the left and right ends of the mounting platform 28. Left tension seats 30 are fixedly installed on the two sets of columns 29 at the left end of the mounting platform 28, and right tension seats 31 are fixedly installed on the two sets of columns 29 at the right end of the mounting platform 28. Two sets of guide rods 32 are fixedly installed between the two sets of left tension seats 30 and the two sets of right tension seats 31. A fourth drive motor 33 is fixedly installed on each of the two sets of left tension seats 30. A first bevel gear 34 is rotatably installed inside each of the two sets of left tension seats 30. The two sets of first bevel gears 34 interact with the two... The output shaft of the fourth drive motor 33 is fixedly connected. A second bevel gear 35 is rotatably installed in each of the two sets of left tension seats 30. The two sets of second bevel gears 35 mesh with the two sets of first bevel gears 34. Four sets of slides 36 are slidably installed on the four sets of guide rods 32 installed between the two sets of left tension seats 30 and the two sets of right tension seats 31. The four sets of slides 36 are symmetrically arranged front and back. A bidirectional lead screw 39 is rotatably installed between the two sets of left tension seats 30 and the two sets of right tension seats 31. The two sets of bidirectional lead screws 39 are connected to the four sets of slides 36 by threads. Two sets of winding assemblies are installed on the four sets of slides 36.

[0045] The output shafts of the two sets of fourth drive motors 33 drive the two sets of first bevel gears 34 to rotate. Since the two sets of first bevel gears 34 mesh with the two sets of second bevel gears 35, the rotation of the two sets of first bevel gears 34 will drive the two sets of second bevel gears 35 to rotate. Furthermore, the two sets of second bevel gears 35 drive the two sets of bidirectional lead screws 39 to rotate synchronously. If the output shafts of the fourth drive motors 33 continue to rotate, the transmission action of the two sets of first bevel gears 34 and the two sets of second bevel gears 35 will cause the two sets of bidirectional lead screws 39 to rotate synchronously. The four sets of slides 36 connected by threads slide on the four sets of guide rods 32, which not only adjusts the distance between the two sets of winding assemblies, but also provides the necessary space for stretching the textile fabric. The sliding of the four sets of slides 36 simultaneously drives the two sets of winding assemblies installed on them to move synchronously. The two sets of winding assemblies are responsible for fixing the textile fabric to the left and right and winding it up during stretching, respectively. During the stretching process, the part of the textile fabric to be tested is clamped by the two sets of winding assemblies. As the two sets of winding assemblies rotate and wind up, the textile fabric is gradually stretched until the predetermined stretching degree is reached.

[0046] like Figures 5 to 7As shown, the winding assembly includes two sets of drive mounting seats 37, which are fixedly mounted on the two side slides 36 at the rear of the four slides 36. Auxiliary support seats 38 are fixedly mounted on one side of each of the four slides 36, symmetrically positioned at the front and rear. A fifth drive motor 40 is fixedly mounted on the lower side of each of the two drive mounting seats 37. Drive pulleys 41 are fixedly mounted on the output shafts of the two fifth drive motors 40. Transmission shafts 42 are mounted on opposite ends of each of the two drive mounting seats 37. Driven pulleys 43 are mounted on the front output shafts of both transmission shafts 42. The two sets of drive pulleys 41 and the two sets of driven pulleys 42... Each pulley 43 is fitted with a drive belt 44. Each of the four sets of auxiliary support seats 38 has a bearing seat 45 installed at one end of each set of opposite supports. Each of the four sets of bearing seats 45 has a roller 46 installed inside. The two sets of drive shafts 42 are fixedly connected to the two sets of auxiliary support seats 38 installed on the two sets of slides 36 and the roller 46 installed inside the two sets of bearing seats 45. Two sets of lower winding rollers 47 are fixedly installed between the four sets of roller 46. Each of the two sets of lower winding rollers 47 has an upper pressure roller 48 installed on its upper side. Adjusting pins 49 are inserted at the contact points between the two sets of upper pressure rollers 48 and the two sets of lower winding rollers 47 on both the front and rear sides.

[0047] The textile fabric is positioned between two sets of lower winding rollers 47 and two sets of upper pressure rollers 48. The output shafts of two sets of fifth drive motors 40 drive two sets of driving pulleys 41, two sets of driven pulleys 43, and two sets of transmission belts 44 to rotate. Furthermore, the rotation of two sets of transmission shafts 42 drives four sets of roller shafts 46, two sets of lower winding rollers 47, and two sets of upper pressure rollers 48 to wind up the fabric. At this time, the textile fabric is stably clamped between the two sets of lower winding rollers 47 and two sets of upper pressure rollers 48. As the two sets of lower winding rollers 47 and two sets of upper pressure rollers 48 rotate... As the fabric is wound up by rotation 8, it is gradually stretched. The rotation speed of the two sets of lower winding rollers 47 and the two sets of upper pressure rollers 48 can be adjusted by controlling the rotation speed of the two sets of drive shafts 42, thereby controlling the stretching speed of the fabric. At the same time, the sliding distance of the four sets of carriages 36 on the four sets of guide rods 32 determines the distance between the two sets of winding components, which in turn determines the stretching length of the fabric. This allows the device to flexibly adjust the stretching speed and stretching length according to different testing requirements, improving the applicability and flexibility of the device.

[0048] like Figures 1 to 10 As shown, an intelligent measurement and control system is installed inside the equipment frame 1. The intelligent measurement and control system is connected to the first guide rail 9, the second drive motor 15, the third drive motor 24, two sets of fourth drive motors 33 and two sets of fifth drive motors 40. Tension sensors and displacement sensors are built into the two sets of lower winding rollers 47 and the two sets of upper pressure rollers 48.

[0049] The intelligent measurement and control system can record and analyze the data transmitted by the tension sensor and displacement sensor in real time, ensuring accurate assessment of the tensile properties of textile fabrics. The tension sensor is responsible for monitoring the magnitude of the tension force borne by the textile fabric during the stretching process, while the displacement sensor is used to track the stretching length of the textile fabric. The detection data is processed by the intelligent measurement and control system to generate detailed test reports, providing a scientific basis for the quality control of textile fabrics.

[0050] like Figures 5 to 7 As shown, the gap between the two sets of lower winding rollers 47 and the two sets of upper pressing rollers 48 on opposite sides is greater than two millimeters, and the edges of the two sets of lower winding rollers 47 and the two sets of upper pressing rollers 48 on opposite sides are all arc-shaped.

[0051] This ensures that the textile fabric is not excessively squeezed or damaged during the stretching process, while also guaranteeing the stability of the fabric during stretching. In addition, the curved edge design helps to reduce the friction between the fabric and the lower winding roller 47 and the upper pressure winding roller 48 during stretching, further protecting the integrity of the fabric.

[0052] like Figures 5 to 7 As shown, the two sets of lower clamping plates 4 and the two sets of upper clamping plates 5 are on the same horizontal plane as the two sets of lower winding rollers 47 and the two sets of upper pressing rollers 48, and the two sets of lower winding rollers 47 and the two sets of upper pressing rollers 48 are located between the two sets of lower clamping plates 4 and the two sets of upper clamping plates 5.

[0053] This method ensures that the textile fabric remains horizontal during the fixing process, avoiding uneven stretching caused by fabric tilting, thus ensuring the accuracy and reliability of the test results. At the same time, it simplifies the operation process and improves the testing efficiency.

[0054] Working principle: The textile fabric is passed between two sets of lower winding rollers 47 and two sets of upper pressure rollers 48, and both ends of the textile fabric are fixed to the two sets of lower clamping plates 4 by two sets of upper clamping plates 5 and four sets of locking bolts 6, thus completing the fixation of the textile fabric. Then, the output shaft of the third drive motor 24 drives the adjusting screw 25 to rotate. Since the adjusting screw 25 is fixedly connected to the output shaft of the third drive motor 24, the rotation of the adjusting screw 25 will drive the two sets of sliding blocks 27 threaded to it to slide left and right on the second guide rail 26, thereby driving the mounting platform 28, the stretching assembly and the detection assembly to move synchronously. Then, the two sets of fourth drive motors 33 are started, and the output shafts of the two sets of fourth drive motors 33... The first bevel gears 34 are driven to rotate. Since the first bevel gears 34 mesh with the second bevel gears 35 respectively, the rotation of the first bevel gears 34 will drive the second bevel gears 35 to rotate synchronously. The rotation of the second bevel gears 35 will further drive the two sets of bidirectional lead screws 39 connected to them to rotate. At this time, if the output shafts of the two sets of fourth drive motors 33 continue to rotate, through the transmission action of the two sets of first bevel gears 34, two sets of second bevel gears 35 and two sets of bidirectional lead screws 39, the four sets of slides 36 threadedly connected to the two sets of bidirectional lead screws 39 will slide closer or further away on the four sets of guide rods 32. The sliding of the four sets of slides 36 not only adjusts the distance between the two winding assemblies, but also... It also provides the necessary space for the stretching of the textile fabric. Then, two sets of fifth drive motors 40 are started. The output shafts of the two sets of fifth drive motors 40 drive two sets of driving pulleys 41, two sets of driven pulleys 43, and two sets of transmission belts 44 sleeved on the two sets of driving pulleys 41 and two sets of driven pulleys 43. Since the two sets of transmission shafts 42 are fixedly connected to the four sets of roller shafts 46, the two sets of transmission shafts 42 will drive the four sets of roller shafts 46 to rotate. At this time, the textile fabric is between the two sets of lower winding rollers 47 and the two sets of upper pressure rollers 48. As the two sets of driving pulleys 41, two sets of transmission shafts 42, two sets of driven pulleys 43, two sets of transmission belts 44 and four sets of roller shafts 46 rotate, the two sets of lower winding rollers 47 and the two sets of upper pressure rollers 48 are wound up, and the textile fabric... As the fabric is gradually stretched, the intelligent measurement and control system records and analyzes the data transmitted by the tension sensor and displacement sensor in real time during the stretching process, ensuring accurate assessment of the fabric's tensile properties. Simultaneously, the output shaft of the first drive motor 11 drives the first drive gear 12 to rotate on the first rack 8. Since the first drive gear 12 meshes with the left side of the first rack 8, its rotation causes the detection frame 10 to slide back and forth on the crossbeam 7 and the first guide rail 9. During this sliding motion, the output shaft of the second drive motor 15 synchronously drives the second drive gear 16 to rotate on the second drive rack 14. Since the second drive gear 16 meshes with the right side of the second drive rack 14...Therefore, the rotation of the second drive gear 16 causes the vertical rod 13 and the second drive rack 14 to slide up and down on the detection frame 10. As the vertical rod 13 and the second drive rack 14 slide up and down, the reinforcing frame 18 and the auxiliary fixing component 19 move synchronously, causing the detection probe 20 to approach the part of the textile fabric to be detected, thereby achieving accurate detection of different positions on the textile fabric.
