This test helps understand how the polyester fabric performs under tensile forces, thereby ensuring its quality and durability. During testing, specialized testing equipment is required, such as the most common universal material testing machine, which can properly perform tensile testing on stretch-resistant polyester fabrics. However, in actual use, certain minor drawbacks still exist. For example, if the tensile strength of the stretch-resistant polyester fabric exceeds the maximum tensile strength of the testing device, the servo drive motor in the testing device will be overloaded, increasing the risk of motor damage and safety hazards, making it difficult to conduct safe testing.

The two support plates 7 are respectively located on both sides above the movable plate 5. The support plate 7 is threadedly connected to the transmission screw inside the bracket 6. The bottom end of the transmission screw inside the bracket 6 is connected to the original transmission screw inside the testing machine through the transmission screw inside the testing machine. The dynamic structure is connected to the output shaft of the servo drive motor installed inside the base 1, which can provide the required kinetic energy for its operation. The lower surface of the support plate 7 is fixed with a vertical cylinder 8, and the bottom end of the vertical cylinder 8 is fixed with a conical block 9. The lower surface of the conical block 9 fits the contact surface of the movable plate 5. The outer wall of the conical block 9 is tightly pressed with an oblique block 10 on both sides. The surface of the oblique block 10 away from the conical block 9 is fixed with a cross bar 11. A square cylinder 12 is provided on the outside of the conical block 9. The bottom end of the square cylinder 12 is fixedly connected to the contact surface of the movable plate 5. The square cylinder 12 is penetrated by the cross bar 11. The outer wall of the cross bar 11 is clearance-matched with the penetration surface of the square cylinder 12. The outer wall of the cross bar 10 is sleeved with a compression spring 13. The coefficient of the compression spring 13 is 20-100N / CM. One end of the compression spring 13 is fixed with a collar 14. The inner wall is fixedly connected to the outer wall of the cross bar 11, and the other end of the compression spring 13 is fixedly connected with a sleeve plate 15, which is penetrated by the cross bar 11, and the outer wall of the cross bar 11 is clearance-matched with the through-surface of the sleeve plate 15.

[0017] The anti-stretching polyester fabric detection device first clamps the upper and lower sides of the fabric 2 to be tested with the first clamp 3 and the second clamp 4 respectively, starts the driving motor inside the base 1, rotates the transmission screw inside the bracket 6, and causes the two support plates 7 to move upward. During this process, the vertical cylinder 8 and the conical block 9 will move together with the support plate 7. Due to the tight relationship between the two oblique blocks 10 and the conical block 9, the two oblique blocks 10, the square cylinder 12, the movable plate 5 and the first clamp 3 will all move upward. During this period, the distance between the first clamp 3 and the second clamp 4 increases to perform a tensile test on the fabric 2. If the tensile strength of the fabric 2 is abnormally strong, the tight force between the conical block 9 and the oblique block 10 continues to increase. During this process, The compression degree of the compression spring 13 continues to increase until the inclined block 10 is separated from the conical block 9. At this time, the movable plate 5 is no longer subjected to the upward tensile force, and the force required for the support plate 7 to continue to transmit upward is rapidly reduced, which can avoid the drive motor from being in an overload state, greatly reduce the probability of motor damage and safety accidents, and facilitate safety inspections. When the above situation occurs, the device should be powered off in time, and then the fabric 2 between the first clamp 3 and the second clamp 4 should be removed, and the cross bar 11 should be applied outward to increase the distance between the two inclined blocks 10. The conical block 9 is re-positioned between the two inclined blocks 10 to make them press against each other, completing the connection operation between the movable plate 5 and the support plate 7 for the next use.
