[0002] Synthetic fiber fabrics are fabrics made of synthetic polymer compounds, the most common ones are polyester, nylon, acrylic, chlorofiber, vinylon, spandex, etc.; there are many types of synthetic fiber fabrics, each with its own characteristics. For example, polyester fabrics are crisp and wrinkle-free, with good strength and wear resistance, but poor moisture absorption. Nylon fabrics are strong and wear-resistant, with good elasticity, but not good enough in terms of sunlight resistance. Acrylic fabrics are bulky and sun-resistant, and are mostly used for wool, yarn, blankets, etc. Chlorofiber fabrics have strong warmth retention and high electrical insulation, but very poor heat resistance. Spandex fabrics have excellent elasticity and are suitable for making underwear, sportswear, etc.; synthetic fiber fabrics are widely used in various fields. Not only for clothing, but also for home, medical, industrial and other fields;

[0050] See also Figure 1 , 2 As shown in 12, a third driving motor 47 is fixedly installed on the upper end of the second movable plate 6, and a pulley 48 is fixedly connected to the output end of the third driving motor 47 and the outer wall of the movable rod 19, and a tension belt 49 is provided between the two sets of pulleys 48.

[0051] The working principle of the present invention is: when the device is used, two forms of fiber fabrics can be fixed. The first form is to fix the fiber fabric wound on the coil tube, and the second form is to fix the cut rectangular fiber fabric.

[0052] The first method is to start the electric telescopic arm 10 above the second movable plate 6 and the first movable plate 3. The electric telescopic arm 10 drives the two groups of elastic telescopic plates 11 to extend upward through the first connecting plate 21, and also drives the two groups of movable blocks 13 to move upward at the same time. The movable block 13 drives the movable rod 19 to move upward, and the movable rod 19 drives the universal ball 27 to slide on the outer wall of the abutment wall 12 through the movable circular tube 28. When the universal ball 27 moves to the curved surface of the abutment wall 12, the first elastic spring 18 will drive the universal ball 27 and the movable circular tube 28 to slowly disengage from the abutment with the curved surface of the abutment wall 12 through the movable rod 19. During the movement, the movable rod 19 drives the sliding sleeve 50 to move through the fixed circular rod 32, and the sliding sleeve 50 drives the second abutment plate 26 toward the direction of the movable rod 19 through the first rotating arm 22. When the second abutment plate 26 moves toward the moving rod 19, the second rotating arm 29 will also be driven to fold, and the second rotating arm 29 will drive the first abutment plate 24 to disengage from the abutment with the mounting tube 14 through the second elastic spring 25. At this time, two groups of mounting tubes 14 can be moved in opposite directions, so that the mounting tubes 14 can be disengaged from the abutment with the first abutment plate 24. At this time, there are still two groups of mounting tubes 14 that have not been disassembled. Then, the fourth elastic telescopic arm 43 at the upper end of the first movable plate 3 is started to drive the corresponding elastic telescopic plate 11 to move, and the elastic telescopic plate 11 drives the corresponding fixing tube mechanism 101 to move. At this time, the interval between the two groups of fixing tube mechanisms 101 is sufficient to put down the winding tube wrapped with fiber fabric, and then the winding tube wrapped with fiber fabric is set on the outer wall of the disassembled first abutment plate 24;

[0053] It is worth noting that, during the above use, only two groups of corresponding mounting tubes 14 are removed, but the mounting tubes 14 of the other two groups are still sleeved on the outer wall of the first abutment plate 24. According to the above working principle, when the first abutment plate 24 shrinks and resets, the first abutment plate 24 will be separated from the abutment with the pneumatic shrink tube 23. The pneumatic shrink tube 23 will be reset to draw gas into the abutment receiving tube 16, and the abutment receiving tube 16 will shrink. At this time, one end of the fiber fabric on the winding tube wrapped with the fiber fabric can be placed between the two groups of abutment receiving tubes 16. When the electric telescopic arm 10 is started again, the electric telescopic arm 10 will drive the moving rod 19 to reset through the moving block 13. When the movable tube 28 inside the universal ball 27 is in contact with the abutment wall 12, the movable tube 28 inside the universal ball 27 is in contact with the abutment wall 12. When abutting, the movable circular tube 28 will be squeezed and contracted by the curved surface on the outer wall of the abutting wall 12. The movable circular tube 28 drives the moving rod 19 and the sliding sleeve 50 to contract simultaneously through the universal ball 27. The sliding sleeve 50 drives the second abutting plate 26 to reset through the first rotating arm 22. The second abutting plate 26 drives the first abutting plate 24 to reset through the second elastic spring 25. When the first abutting plate 24 at the upper end of the first movable plate 3 is reset, it will abut and fix with the inner wall of the winding tube wrapped with fiber fabric. The first abutting plate 24 at the upper end of the second movable plate 6 will squeeze the pneumatic shrink tube 23 inside the installation circular tube 14. The gas inside the pneumatic shrink tube 23 enters the abutting receiving shrink tube 16. The two groups of abutting receiving shrink tubes 16 fix one end of the fabric.

[0054] The first method is that, according to the above working principle, the mounting round tubes 14 on the upper ends of the first movable plate 3 and the second movable plate 6 are not disassembled, and the two ends of the cut rectangular fiber fabric are placed between the two sets of abutting and shrinking tubes 16 on the upper ends of the first movable plate 3 and the second movable plate 6. When the two sets of abutting and shrinking tubes 16 are closed, the fiber fabric can be clamped and fixed;

[0055] When testing is required, the third drive motor 47 is started, and the third drive motor 47 drives one group of pulleys 48 to rotate. The pulley 48 drives the pulley 48 on the outer wall of the moving rod 19 at the upper end of the second moving plate 6 to rotate through the tension belt 49. When the moving rod 19 rotates, it will drive the corresponding first abutment plate 24 to rotate. The first abutment plate 24 will drive the two groups of fiber fabrics fixed between the abutment receiving and shrinking tubes 16 to wrap around each other, and the fiber fabric can be pulled. When the fiber fabric is pulled, the two groups of moving blocks 13 at the upper end of the first moving plate 3 are moved by the tension, and the two groups of moving blocks 13 pull the tension sensor 17 through the first connecting plate 21. When the fiber fabric is broken or damaged, the value at the upper end of the tension sensor 17 is recorded to measure the strength of the fiber fabric.

[0056] In the above, when the fiber fabric is stretched and straightened to test the strength, the second drive motor 35 can be started. The second drive motor 35 drives the swing arm 37 to rotate through the rotating wheel 34. Since the swing arm 37 is not installed at the center of the rotating wheel 34, the swing arm 37 is in an up and down motion state at this time. The swing arm 37 will drive the elastic bending plate 39 to move up and down through the shaking plate 38. When the elastic bending plate 39 abuts against the fiber fabric, the elastic bending plate 39 will be compressed and deformed. The elastic bending plate 39 moves on the inner wall of the slide groove 40 through the sliding block, and the sliding block will abut against the touched abutment ball 42. The squeezed abutment ball 42 will slide into the installation groove 46, and the abutment ball 42 will squeeze the touch sensing switch 45. At this time, the corresponding scale light 41 will light up, and the data of the triggered touch sensing switch 45 will also be transmitted to the inside of the display panel 8. The staff can detect the toughness of the fiber fabric through the display panel 8.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
