To address these issues, this invention provides an elasticity testing device for composite fabric production. Utility Model Content

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0018] An elasticity testing device for composite fabric production, such as Figures 1-5 As shown, the device includes a testing platform 1. A first vertical arm 2 and a second vertical arm 3 are vertically mounted on the top of the testing platform 1. The first vertical arm 2 is vertically fixed to the testing platform 1, while the second vertical arm 3 is movable relative to the testing platform 1. A tension drive component is provided at the bottom of the testing platform 1 to move the second vertical arm 3 closer to or away from the first vertical arm 2. Guide grooves 5 are provided on the testing platform 1 along the moving direction of the second vertical arm 3. The bottom end of the second vertical arm 3 passes through the guide grooves 5, and two pairs of protrusions are provided on the side wall of the bottom end of the second vertical arm 3. The two pairs of protrusions slide and fit against the upper and lower surfaces of the testing platform 1, respectively. This design ensures the stability of the second vertical arm 3 during movement. Ball bearings or rollers can be installed between the protrusions and the surface of the testing platform 1 to reduce frictional resistance and improve testing accuracy.
[0019] In this embodiment, the tension drive is a first electric push rod 6 installed at the bottom of the testing platform 1. The telescopic end of the first electric push rod 6 is equipped with a pressure sensor 10 and is connected to the bottom end of the second vertical arm 3. When the first electric push rod 6 is activated, its telescopic end will drive the second vertical arm 3 to move within the guide groove 5, thereby enabling the second vertical arm 3 to move closer to or further away from the first vertical arm 2.
[0020] Furthermore, both the first vertical arm 2 and the second vertical arm 3 are equipped with electrically driven clamping components 4 at their top ends. The electrically driven clamping components 4 include a lower clamping plate 14 fixed to the top of the first vertical arm 2 and the second vertical arm 3, and an upper clamping plate 13 located above the lower clamping plate 14. A third electric push rod 15 is vertically fixed to the lower clamping plate 14. The telescopic end of the third electric push rod 15 passes through the lower clamping plate 14 and connects to the upper clamping plate 13. The sides of the upper clamping plate 13 and the lower clamping plate 14 facing each other towards the center of the testing table 1 are provided with interlocking toothed ridges 16. This structure allows the upper clamping plate 13 and the lower clamping plate 14 to move closer or further apart under the action of the third electric push rod 15, thereby achieving the clamping or releasing of the composite fabric to be tested placed between them. The toothed ridges 16 increase the friction of the clamping, ensuring the stability of the clamping.
[0021] Furthermore, a recycling box 9 is provided on one side of the first vertical arm 2 and the second vertical arm 3. The recycling box 9 is movably embedded in the detection table 1 for easy disassembly and cleaning. A material ejection arm 7 and a material ejection drive are provided between the first vertical arm 2 and the second vertical arm 3. The material ejection drive pushes the material ejection arm 7 to force the composite fabric to be tested, which is held between a pair of electrically driven clamping members 4, to move toward the recycling box 9. Specifically, the material ejection arm 7 is configured with a "U" shape, and the opening of the material ejection arm 7 is horizontally distributed on the side facing the recycling box 9, allowing the composite fabric to be tested to pass through the material ejection arm 7. The unloading drive unit includes a fixed arm 17 vertically fixed on the detection table 1 and a second electric push rod 8 horizontally installed on the fixed arm 17. The second electric push rod 8 is located on the side of the unloading arm 7 away from the recycling box 9. The telescopic end of the second electric push rod 8 passes through the fixed arm 17 and is connected to the closed end of the unloading arm 7. The closed end of the unloading arm 7 is also connected to a guide rod 18. The guide rod 18 is parallel to the second electric push rod 8 and moves through the fixed arm 17. The guide rod 18 plays a guiding role to ensure the stability of the unloading arm 7 during movement.
[0022] Furthermore, a magnetostrictive displacement sensor 12 is mounted at the bottom of the detection table 1, parallel to the first electric push rod 6. A support rod 11 is provided on the bottom side wall of the second vertical arm 3, and the support rod 11 is connected to the vernier magnetic ring on the magnetostrictive displacement sensor 12. When the second vertical arm 3 moves, it will drive the vernier magnetic ring to move through the support rod 11. The magnetostrictive displacement sensor 12 can detect the distance the vernier magnetic ring moves, thereby reflecting the moving distance of the second vertical arm 3. The magnetostrictive displacement sensor 12 is an existing sensing device and will not be described in detail in this application.
[0023] Furthermore, a blocking spring 19 is provided on the top of the side of the recycling box 9 facing the first vertical arm 2 and the second vertical arm 3. The blocking spring 19 is distributed upwardly on the side facing the inside of the recycling box 9, and the top of the blocking spring 19 is set higher than the unloading arm 7. This design can block the fabric when it is pushed above the recycling box 9 and make it fall smoothly into the recycling box 9. In addition, a handle 20 is also provided on the recycling box 9 for easy handling.
[0024] The working principle of this utility model: When performing elasticity testing on composite fabrics, the two ends of the composite fabric to be tested are first placed between the upper clamping plate 13 and the lower clamping plate 14 of a pair of electrically driven clamping members 4. The third electric push rod 15 is activated to bring the upper clamping plate 13 and the lower clamping plate 14 closer to each other. The composite fabric to be tested is firmly clamped by the toothed edge 16 and then passes through the unloading arm 7.
[0025] Then, the first electric push rod 6 is activated. The telescopic end of the first electric push rod 6 drives the second vertical arm 3 away from the first vertical arm 2. Simultaneously, the pressure sensor 10 detects the tension on the telescopic end of the first electric push rod 6 in real time, which is the tension applied to the composite fabric to be tested. During the movement of the second vertical arm 3, the second vertical arm 3 drives the vernier magnetic ring on the magnetostrictive displacement sensor 12 to move through the support rod 11. The magnetostrictive displacement sensor 12 detects the distance the vernier magnetic ring moves, which is the distance the second vertical arm 3 moves, and thus the length of the composite fabric to be tested stretched. Based on the magnitude of the tension and the stretch length, the elasticity of the composite fabric to be tested can be detected. Alternatively, the first electric push rod 6 can be set to drive the second vertical arm 3 away from the first vertical arm 2 by a certain distance, and then the pressure sensor 10 can detect the force required to move that distance, thereby detecting the elasticity of the fabric.
[0026] After the inspection is completed, the second electric push rod 8 is activated. The telescopic end of the second electric push rod 8 pushes the unloading arm 7 towards the recycling box 9. The unloading arm 7 pushes the inspected fabric towards the recycling box 9. At the same time, the first electric push rod 6 drives the second vertical arm 3 to reset and move closer to the first vertical arm 2, cooperating to push the fabric towards the recycling box 9. When the fabric is pushed above the recycling box 9, it will fall into the recycling box 9 for collection due to the blocking effect of the blocking spring 19. At this time, the third electric push rod 15 is controlled to separate the upper clamping plate 13 and the lower clamping plate 14, releasing the fabric at both ends. Finally, the second electric push rod 8 drives the unloading arm 7 to reset, and the next fabric can be inspected.
