In the textile industry, the tensile strength test of fabrics is of great significance for ensuring product quality, improving production processes, and developing new materials. Existing fabric tensile strength testing devices mostly use electronic tensile testing machines. The fabric is fixed by clamps, and then tensile force is applied until the fabric breaks, and its tensile strength is measured;

This helps manufacturers determine whether the fabric meets the product design and usage requirements, and ensures that the produced fabric meets the expected technical standards and performance indicators; in addition, understanding the tensile characteristics of the fabric can provide key data for product design. Designers can select the appropriate fabric type and thickness based on the test results to ensure that the product has the required strength and durability during use.

Both ends of the top of the testing table 1 are slidably connected with L-shaped moving frames 2. The inside of the L-shaped moving frame 2 is slidably connected with a longitudinal moving block 3. The bottom of one side of the longitudinal moving block 3 is provided with a liftable rectangular lower pressing plate 4;

[0033] A moving mechanism for the longitudinal movement of the longitudinal moving block 3 is arranged inside the L-shaped moving frame 2;

[0034] An adjusting mechanism for adjusting the gap between the two L-shaped moving frames 2 is arranged at the bottom of the testing table 1;

[0035] A lifting mechanism for lifting the rectangular lower pressing plate 4 is arranged on one side of the longitudinal moving block 3;

[0036] A transverse through groove is formed inside the L-shaped moving frame 2, so that the fabric can pass through the transverse through groove and penetrate through the inside of the L-shaped moving frame 2;

[0037] Among them, the moving mechanism includes a first driving motor 5. The first driving motor 5 is bolted and fixed to one side of the L-shaped moving frame 2. The output end of the first driving motor 5 is fixed with a first longitudinal threaded rod 6. The first longitudinal threaded rod 6 penetrates through the inside of the longitudinal moving block 3 and is threadedly connected with the longitudinal moving block 3;

[0038] A longitudinal optical rod 7 is fixed inside the L-shaped moving frame 2. The longitudinal optical rod 7 penetrates through the inside of the longitudinal moving block 3 and is slidably connected with the longitudinal moving block 3. Furthermore, the longitudinal moving block 3 can slide on the outside of the longitudinal optical rod 7. The movement of the longitudinal moving block 3 enables the first driving motor 5 to move longitudinally to adjust the longitudinal position of the rectangular lower pressing plate 4;

[0039] A longitudinal rectangular groove is formed inside the L-shaped moving frame 2. The longitudinal moving block 3 is located inside the longitudinal rectangular groove and is slidably connected with the L-shaped moving frame 2 through the longitudinal rectangular groove, so that the longitudinal moving block 3 can longitudinally slide inside the L-shaped moving frame 2;

[0040] Here, the operation of the first drive motor 5 enables the first longitudinal threaded rod 6 to rotate. The rotation of the first longitudinal threaded rod 6 enables the longitudinal moving block 3 to slide outside the longitudinal optical rod 7, thereby enabling the longitudinal position of the rectangular lower pressing plate 4 to be adjusted;

[0041] The lifting mechanism includes a second drive motor 8. One end of the longitudinal moving block 3 is bolted with the second drive motor 8. The output end of the second drive motor 8 is fixed with a rectangular rotating column 9.

The top of the electronic tensile testing machine 22 is fixedly connected to an L-shaped moving frame 2;

[0046] A transverse sliding groove adapted to the electronic tensile testing machine 22 is formed inside the test bench 1.

[0047] A dovetail slider is fixedly provided at the top of the longitudinal moving plate 17. A dovetail sliding groove adapted to the dovetail slider is formed inside the test bench 1. The longitudinal moving plate 17 and the test bench 1 are slidably connected through the cooperation of the dovetail slider and the dovetail sliding groove. Through the arrangement of the dovetail slider and the dovetail sliding groove, the longitudinal moving plate 17 can slide longitudinally inside the test bench 1, so that the rotation of the second longitudinal threaded rod 16 can drive the longitudinal moving plate 17 to move longitudinally;

[0048] A transverse sliding column 19 is fixedly connected to the bottom of the electronic tensile testing machine 22. A transverse limiting column 20 is slidably connected inside the transverse sliding column 19. One end of the transverse limiting column 20 is fixedly provided with a rectangular support plate 21. The top of the rectangular support plate 21 is fixedly connected to the bottom of the test bench 1, so that the transverse sliding column 19 can slide outside the transverse limiting column 20, and the transverse limiting column 20 can provide a guiding for the moving track inside the transverse sliding column 19, so that the electronic tensile testing machine 22 can slide inside the test bench 1;

[0049] Here, the operation of the third driving motor 15 enables the second longitudinal threaded rod 16 to rotate. The rotation of the second longitudinal threaded rod 16 enables the longitudinal moving plate 17 to slide longitudinally at the bottom of the test bench 1. The movement of the longitudinal moving plate 17 enables the transverse sliding column 19 to slide outside the transverse limiting column 20 through the oblique rotating column 18. The sliding of the transverse sliding column 19 enables the electronic tensile testing machine 22 to move. The movement of the electronic tensile testing machine 22 enables the L-shaped moving frame 2 to move, so that the fabric on the top of the L-shaped moving frame 2 can be pulled;

[0050] Working principle: When using the test device of this technical solution, the fabric can pass through the horizontal through groove, so that the fabric can penetrate into the interior of the L-shaped moving frame 2. The operation of the first driving motor 5 enables the first longitudinal threaded rod 6 to rotate. The rotation of the first longitudinal threaded rod 6 enables the longitudinal moving block 3 to slide on the outside of the longitudinal optical rod 7, so that the longitudinal position of the rectangular lower pressing plate 4 can be adjusted.

[0051] The operation of the second driving motor 8 enables the rectangular rotating column 9 to rotate. The rotation of the rectangular rotating column 9 makes the vertical lifting rod 11 slide vertically on the outside of the horizontal support plate 12 through the rectangular transmission column 10. Thus, the vertical lifting rod 11 can drive the rectangular lower pressing plate 4 to move towards the fabric, so that the rectangular lower pressing plate 4 can fix the fabric on the top of the L-shaped moving frame 2. At this time, the rigid spring 13 is in a state of being stretched under force.

[0052] The operation of the third driving motor 15 enables the second longitudinal threaded rod 16 to rotate. The rotation of the second longitudinal threaded rod 16 enables the longitudinal moving plate 17 to slide longitudinally at the bottom of the test bench 1. The movement of the longitudinal moving plate 17 makes the horizontal sliding column 19 slide on the outside of the horizontal limiting column 20 through the oblique rotating column 18. The sliding of the horizontal sliding column 19 enables the electronic tensile testing machine 22 to move. The movement of the electronic tensile testing machine 22 enables the L-shaped moving frame 2 to move, so that the fabric on the top of the L-shaped moving frame 2 can be pulled. Through the setting of the electronic tensile testing machine 22, the tensile force of the fabric can be detected.

[0053] All the technical features in this embodiment can be freely combined according to actual needs.

[0054] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present utility model.
