When the take-up roller rotates, a tension sensor can detect the tension force on the fabric during the stretching process, and a displacement sensor can detect the stretching length of the fabric, making it convenient and practical.

Description

Technical Field

[0001] This utility model belongs to the field of textile fabric testing technology, and specifically relates to a device for testing the tensile strength of textile fabrics. Background Technology

[0002] Textile fabrics, classified by weaving method, are divided into two categories: 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., using plain knit, modified plain knit, rib plain knit, double rib plain knit, jacquard, terry knit, etc., woven on various weft knitting machines. After the textile fabric is processed, it is generally subjected to tensile strength testing to check whether it meets the requirements for subsequent use.

[0003] Chinese patent CN218885619U discloses a textile fabric tensile strength testing device, which solves the problems of inconvenience in fixing the fabric during tensile testing and inconvenience in wetting the fabric when wet testing is required in the prior art. The textile fabric tensile strength testing device includes a frame, a support rod rotatably connected to the inner side of the frame, and a support sleeve fitted on the support rod. A cylinder is fixedly connected to the bottom of the frame by bolts.

[0004] However, the above structure still has some shortcomings. When performing tensile testing on textile fabrics, the above structure uses two rotating rods to roll up the position, which makes it difficult to feed the material and also makes it difficult to limit the position of the textile fabric for testing. This can easily lead to inaccurate test data, which is very inconvenient. Utility Model Content

In use, one end of the textile fabric to be tested is placed on the take-up roller 5, and the other end of the textile fabric is placed on the top of the base plate 8. Then, the screw 15 is turned, and the rotating shaft 13 can make the end of the screw 15 rotate in place, while the pressure plate 10 is pressed down. By clamping the pressure plate 10 and the base plate 8, the other end of the textile fabric can be effectively clamped and limited, thereby effectively improving the stability of the fabric position limitation stretching. When the take-up roller 5 rotates, the tension sensor 6 can detect the tension force on the fabric during the stretching process, and the displacement sensor 7 can detect the stretching length of the fabric, which is convenient and practical.

[0024] refer to Figure 1 and Figure 3 The bottom end of the support platform 1 is threaded with a bolt 23. The top end of the bolt 23 is threaded into the inside of the base plate 8. The base plate 8 is threaded to the inner bottom of the protective frame 2 by the bolt 23. Due to the presence of the bolt 23, the bolt 23 can be screwed in to effectively fix the position of the base plate 8, thereby preventing the base plate 8 from shifting. It also makes it easier for the user to disassemble and install the base plate 8 separately for maintenance or cleaning.

[0025] refer to Figure 3 An anti-slip pad 25 is fixedly connected to the bottom end of the pressure plate 10. The anti-slip pad 25 is five millimeters thick and covers the bottom end of the pressure plate 10. The anti-slip pad 25 is made of rubber material. Due to the presence of the anti-slip pad 25, the anti-slip pad 25 can effectively improve the friction of the bottom end of the pressure plate 10, thereby further improving the stability of the textile fabric position clamping and preventing the textile fabric from shifting.

[0026] refer to Figures 1 to 3The bottom end of the limiting plate 11 is fixedly connected to a telescopic rod 12, and the bottom end of the telescopic rod 12 is fixedly connected to the top end of the pressure plate 10. The screw 15 is located on the inner side close to the telescopic rod 12. A first sliding groove 9 matching the pressure plate 10 is opened on the inner wall of the protective frame 2. The pressure plate 10 is slidably connected to the inner wall of the protective frame 2 through the first sliding groove 9. The telescopic rod 12 includes a movable rod and a sleeve rod. The movable rod is sleeved on the inner side of the sleeve rod. Due to the presence of the telescopic rod 12, the telescopic rod 12 can provide secondary support and traction to the top end of the pressure plate 10 without hindering the adjustment of the height of the pressure plate 10, thereby effectively improving the stability of the height adjustment of the pressure plate 10.

[0027] refer to Figures 1 to 3 The protective frame 2 has an opening 16 at its inner bottom end, which penetrates both the protective frame 2 and the support platform 1. An inclined plate 17 is fixedly connected to the inner wall of the opening 16. A support leg 18 is fixedly connected to the bottom end of the support platform 1, and a base frame 19 is fixedly connected to the inner side of the support leg 18. A collection box 21 is slidably connected to the top of the base frame 19, with the position of the collection box 21 corresponding to the position of the inclined plate 17. A second sliding groove 20 matching the collection box 21 is provided at the top of the base frame 19, allowing the collection box 21 to be slidably connected to the top of the base frame 19 via the second sliding groove 20. A handle 22 is fixedly connected to the front of the collection box 21. The handle 22 has an arc-shaped corner. After the textile fabric is inspected, the screw 15 is loosened so that the textile fabric is located at the position of the inclined plate 17. Then, the textile fabric is discharged by rotating the take-up roller 5 in the opposite direction. The inspected textile fabric can fall into the collection box 21 through the traction of the inclined plate 17. The collection box 21 can collect the inspected textile fabric in a unified manner, thereby achieving the effect of convenient and fast unloading, and can also effectively improve the efficiency of subsequent inspection of textile fabric.

[0028] refer to Figure 1 and Figure 4 A control module 24 is installed on the outer wall of the protective frame 2, and a power supply module is installed inside the support platform 1. The power supply modules inside the support platform 1 are all connected to the control module 24, the drive motor 3, the tension sensor 6, and the displacement sensor 7. The control module 24 is also connected to the drive motor 3, the tension sensor 6, and the displacement sensor 7. Due to the presence of the power supply module, the electrical equipment on the device can be effectively powered. The control module 24 can effectively control the electrical equipment on the device. It is more convenient and faster to operate the device through the control module 24.

[0029] Operating principle and advantages: In use, one end of the textile fabric to be tested is placed on the take-up roller 5, and the other end is placed on the top of the base plate 8. Then, screwing the screw 15 causes the shaft 13 to rotate in place, pressing the pressure plate 10 downwards. The pressure plate 10 and the base plate 8 clamp the other end of the textile fabric, effectively limiting its position and improving the stability of the fabric's stretching. When the take-up roller 5 rotates, the tension sensor 6 detects the tension on the fabric during stretching, and the displacement sensor 7 detects the stretching length. This is convenient and practical. The bolt 23 effectively fixes the position of the base plate 8, preventing displacement and facilitating easy disassembly and cleaning. The presence of the anti-slip pad 25 effectively increases the friction at the bottom of the pressure plate 10, thereby further improving the stability of the textile fabric clamping position and preventing displacement of the textile fabric. Due to the presence of the telescopic rod 12, the telescopic rod 12 can provide secondary support and traction to the top of the pressure plate 10 without hindering the adjustment of the height of the pressure plate 10, thereby effectively improving the stability of the height adjustment of the pressure plate 10. After the textile fabric is inspected, the screw 15 is loosened first so that the textile fabric is located at the position of the inclined plate 17, and then the textile fabric is discharged by rotating the take-up roller 5 in the opposite direction. The inspected textile fabric can fall into the collection box 21 through the traction of the inclined plate 17. The collection box 21 can collect the inspected textile fabric in a unified manner, thereby achieving the effect of convenient and fast unloading, and also effectively improving the efficiency of subsequent inspection of the textile fabric.
