Description

Technical Field

[0001] The invention relates to the technical field of tensile testing, and in particular to a device for testing the tensile strength of textile fabrics. Background Art

[0002] Textiles are products made from processed textile fibers, and are divided into two categories: woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles. In ancient times, silk fabrics were basically named according to fabric organization, fabric pattern, and fabric color. Modern silk still uses many old names, such as crepe, damask, silk, and silk, and also uses some foreign words, such as georgette and taffeta.

[0003] In order to solve the problem that "existing equipment cannot perform double-sided force stretching on fabrics", a Chinese patent with publication number CN219179100U discloses a textile tensile strength testing device for textile testing, including a control panel and a top plate. Empty slots are provided on both sides of the control panel, and a placement slot is provided inside the front end of the control panel. A double-headed motor is fixed in the middle of the placement slot. An active bevel gear is fixed to the driving end of the double-headed motor, and a driven bevel gear is meshed and connected to the other end of the active bevel gear. A rotating rod is fixed at the rear center of the driven bevel gear, and a rotating roller is fixed to the outside of the rotating rod. An electric telescopic rod is fixed at the bottom middle end of the top plate. Although the existing technical problems have been solved, the following problems still exist:

[0004] In this technical solution, the end of the stretching test can only be determined by visually observing whether cracks appear on the fabric during the stretching process. However, very small cracks are difficult to see with the naked eye, which results in a large error. Therefore, corresponding improvements are made to address this problem. Summary of the invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a textile fabric tensile strength testing device.

The water in the water tank flows onto the fabric through the outlet pipe, and the water penetrates the fabric and drips into the gathering tank, and then flows down through the drain.

[0032] Reference Figure 1-9A textile fabric tensile strength testing device comprises a bottom plate 1, a support plate 2 is fixed on the top of the bottom plate 1, a mounting plate 3 is fixed on the top of the support plate 2, a stretching mechanism is arranged on the mounting plate 3 for stretching the fabric, a water tank 4 is arranged above the mounting plate 3, the water tank 4 is fixed on the mounting plate 3 through a pair of support frames 23, a plurality of evenly distributed water outlet pipes 5 are arranged at the bottom of the water tank 4, a pressing plate 6 is arranged in the water tank 4, a pressing rod 7 is fixed on the top of the pressing plate 6, a gathering groove 8 is opened on the top of the mounting plate 3, a drainage port 9 penetrating the mounting plate 3 is opened on the bottom wall of the gathering groove 8, and a water tank 4 is pre-arranged to form a water outlet 9. The water tank 4 is filled with water, and then the fabric is stretched by the stretching mechanism, and then the pressure plate 6 is pushed downward by pressing the pressure rod 7. The water in the water tank 4 flows onto the fabric through the outlet pipe 5. The water penetrates the fabric and drips into the collecting tank 8, and then flows down through the drain port 9. At this time, you only need to observe the water flow at the drain port 9. If a certain water flow appears to be larger, it means that the fabric has been torn at the corresponding position above the water flow. If there is no obvious difference in the water flow at the drain port 9, it means that the fabric has not been torn and can continue to be stretched, so that a more accurate stretch test result can be measured.

[0033] Furthermore, a support plate 10 is provided at the front end of the support plate 2, and L-shaped positioning frames 11 are provided on both sides of the support plate 2. A water receiving box 12 located below the drain outlet 9 is provided between the support plate 10 and the positioning frame 11. A plurality of evenly distributed water receiving chambers 13 are provided on the top of the water receiving box 12. The water receiving box 12 is transparent, and the water flowing from the drain outlet 9 will flow into the corresponding water receiving chamber 13. In this way, the height of the liquid level in each water receiving chamber 13 can be directly checked. When the liquid level in a certain water receiving chamber 13 is significantly higher than the other liquid levels, it means that the fabric has been torn, which makes the viewing more intuitive.

Stretching rollers 19 are arranged in the gaps on both sides of the mounting plate 3. Both ends of the stretching roller 19 are rotatably connected to the mounting plate 3 through the main shaft 17. The end of the main shaft 17 close to the first motor 14 is fixedly sleeved with a second bevel gear 18 meshing with the first bevel gear 16. The two ends of the fabric are respectively fixed to the corresponding stretching rollers 19, and then the first motor 14 is started. The output shaft of the first motor 14 drives the first bevel gear 16 to rotate, and the first bevel gear 16 meshes to drive the main shaft 17 to rotate.

The mounting frame 24 is slidably connected to a cross plate 27, and the pressure rod 7 is fixed to the bottom of the cross plate 27. The second motor 25 is started, and the output shaft of the second motor 25 drives the screw rod 26 to rotate, so that the cross plate 27 moves downward, and the cross plate 27 synchronously drives the pressure rod 7 to move downward, thereby pressing the water in the water tank 4 out.

[0037] Furthermore, a push plate 28 capable of moving back and forth on the fabric surface is provided above the mounting plate 3. When moving, the push plate 28 pushes the water on the fabric surface back and forth, so that the water can cover the entire surface of the fabric.
