Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A fiber impact resistance testing device includes an operating table 1. A second connecting block 13 is fixedly connected to the top of the operating table 1. A first connecting block 12 is provided on the outer side of the second connecting block 13. An impact block 9 is provided on the outer side of the first connecting block 12. Two fixed seats 6 are fixedly connected to the top of the operating table 1. Two movable seats 20 are provided on the top of the operating table 1. The two fixed seats 6 and the movable seats 20 are arranged symmetrically to each other. The device also includes:

[0030] A movable impact assembly, located on the outer surface of the second connecting block 13 and connected to the impact block 9, is used to adjust the impact position of the impact block 9, thereby enabling the detection of multiple positions of the fiber material.

[0031] Two sets of pressing components, located on top of the operating table 1 and on both sides of the movable impact component, are used to fix the fiber material on both sides.

[0032] An adjustment component, located on the outer surface of the operating table 1 and connected to two movable seats 20, is used to synchronously adjust the positions of the two movable seats 20 and place the fiber material to be tested on the fixed plate 28.

[0033] Furthermore, the movable impact assembly includes a first guide rail 3, a second pulley 11, a third motor 14, a first slider 23, and a second belt 27. The second connecting block 13 is arranged in a T-shape. Two second pulleys 11 are rotatably connected to the front outer surface of the second connecting block 13, and the outer surfaces of the two second pulleys 11 are fitted with the second belt 27. The third motor 14 is fixedly installed on the rear outer surface of the second connecting block 13, and the output end of the third motor 14 is fixedly connected to the adjacent second pulley 11. The front outer surface of the second connecting block 13 is fixedly connected with... Two first guide rails 3 are located outside the two second pulleys 11. The outer surfaces of the two second pulleys 11 are slidably connected to first sliders 23. The two first sliders 23 are fixedly connected to the first connecting block 12. The first connecting block 12 is fixedly sleeved with the second belt 27. The output end of the push cylinder 4 pushes the impact block 9 forward until the impact block 9 contacts the fiber material and generates an impact. Since the impact block 9 is slidably connected to the second guide rail 24 through the second slider 25, this design ensures the stability and accuracy of the impact block 9 during the impact process.

[0034] Furthermore, a push cylinder 4 is fixedly installed on the top of the first connecting block 12. Two symmetrically distributed second guide rails 24 are fixedly connected to the front outer surface of the first connecting block 12. A second slider 25 is slidably connected to the outer surface of each of the two second guide rails 24. The two second sliders 25 are fixedly connected to the impact block 9. The output end of the push cylinder 4 is fixedly connected to the impact block 9. The third motor 14 drives the second pulley 11 connected to it to rotate, and then drives the other second pulley 11 to rotate synchronously through the second belt 27. This transmission method ensures that the two second pulleys 11 can rotate synchronously and stably. As the second belt 27 rotates, the first connecting block 12 fixedly sleeved with it will move horizontally along the first guide rail 3. The first guide rail 3 provides a stable moving path for the first slider 23, ensuring that the impact block 9 can move accurately to the designated position.

[0035] Furthermore, the pressing assembly includes a support frame 2, a first motor 5, a bidirectional threaded rod 7, a moving block 8, a slide 15, a pressure plate 16, and a second belt 27. Two support frames 2 are fixedly connected to the top of the operating table 1, and a bidirectional threaded rod 7 is rotatably connected between the two support frames 2. The first motor 5 is fixedly mounted on the outer surface of one of the support frames 2, and the output end of the first motor 5 is fixedly connected to the end of the bidirectional threaded rod 7. Two symmetrically distributed moving blocks 8 are threaded onto the outer surface of the bidirectional threaded rod 7, and connecting blocks 8 are rotatably connected to both sides of each moving block 8. The outer surfaces of the rod 29 and the two support frames 2 are provided with grooves 15. A pressure plate 16 is slidably connected between the two grooves 15. The pressure plate 16 is rotatably connected to the other end of the four connecting rods 29. The first motor 5 drives the bidirectional threaded rod 7 to rotate. Since the outer surface of the bidirectional threaded rod 7 is threaded with two symmetrically distributed moving blocks 8, when the bidirectional threaded rod 7 rotates, the two moving blocks 8 will move in opposite directions. As the moving blocks 8 move, the connecting rods 29 connected to them will push the pressure plate 16 to move along the grooves 15 towards the fiber material.

[0036] Furthermore, a fixing plate 28 is fixedly connected between the two support frames 2. The top of the fixing plate 28 has two symmetrically distributed slots 19. The pressure plate 16 is arranged in a π-shaped structure. The pressure plate 16 is inserted into the two slots 19 and the pressure plate 16 is inserted into the slots 19 on the fixing plate 28, so as to ensure that the pressure plate 16 can firmly press down on both sides of the fiber material.

[0037] Furthermore, the adjustment assembly includes a second motor 10, a first pulley 17, a first belt 18, a threaded rod 21, and rectangular slots 22. Two rectangular slots 22 are formed on the top of the operating platform 1. Threaded rods 21 are rotatably connected to the interior of each rectangular slot 22. The two rectangular slots 22 are slidably connected to corresponding movable seats 20, and the two movable seats 20 are threadedly engaged with their corresponding rectangular slots 22. Two first pulleys 17 are rotatably connected to the outer surface of the operating platform 1. First belts 18 are fitted onto the outer surfaces of the two first pulleys 17, and the two first belts 18 are threadedly engaged with their corresponding rectangular slots 22. The end of the threaded rod 21 is fixedly connected, and an adapter plate is fixedly connected to the outer surface of the operating table 1. A second motor 10 is fixedly installed on the outer surface of the adapter plate. The output end of the second motor 10 is fixedly connected to the adjacent first pulley 17. The second motor 10 drives the two threaded rods 21 to rotate synchronously through the first pulley 17 and the first belt 18. Since the movable seat 20 is threadedly connected to the threaded rod 21 and slidably connected to the rectangular groove 22, when the threaded rod 21 rotates, the movable seat 20 will move horizontally along the rectangular groove 22, thereby realizing the synchronous adjustment of the two movable seats 20.

[0038] Furthermore, an acceleration sensor 26 is fixedly installed on the top of the impact block 9. The data collected by the acceleration sensor 26 can be used to analyze the impact resistance of the fiber material, thereby providing a scientific basis for the application of the material.

[0039] Working principle: When the operator needs to use this fiber impact resistance testing device, firstly, the fiber material to be tested is placed on the fixed plate 28, and then the first motor 5 is started. The first motor 5 drives the bidirectional threaded rod 7 to rotate. Since the outer surface of the bidirectional threaded rod 7 is threaded with two symmetrically distributed moving blocks 8, when the bidirectional threaded rod 7 rotates, the two moving blocks 8 will move in opposite directions. As the moving blocks 8 move, the connecting rod 29 connected to them will push the pressure plate 16 to move along the slide groove 15 towards the fiber material, so that the pressure plate 16 is inserted into the slot 19 on the fixed plate 28, ensuring that the pressure plate 16 can be firmly engaged. The two sides of the fiber material are pressed down to prevent it from moving during the impact test. When the position of the impact block 9 needs to be adjusted to test different areas of the fiber material, the third motor 14 is started. The third motor 14 drives the connected second pulley 11 to rotate, which in turn drives another second pulley 11 to rotate synchronously via the second belt 27. This transmission method ensures that the two second pulleys 11 can rotate synchronously and stably. As the second belt 27 rotates, the first connecting block 12, which is fixedly sleeved with it, will move horizontally along the first guide rail 3. The first guide rail 3 provides a stable movement path for the first slider 23, ensuring... The impact block 9 can be precisely moved to a designated position. Once the first connecting block 12 reaches the desired position, the push cylinder 4 is activated. The output of the push cylinder 4 pushes the impact block 9 forward until it contacts the fiber material and generates an impact. Because the impact block 9 is slidably connected to the second guide rail 24 via the second slider 25, this design ensures the stability and accuracy of the impact block 9 during the impact process. The impact acceleration generated by the impact block 9 striking the fiber material is monitored and recorded in real time by the acceleration sensor 26. The data collected by the acceleration sensor 26 can be used to analyze the impact resistance of the fiber material, thereby providing insights for the material's application... To provide scientific basis, when it is necessary to test rolled fiber materials, the rolled fiber materials can be placed on the fixed seat 6 and the movable seat 20 located on the same side. Another fixed seat 6 and the movable seat 20 are used to place the take-up roller. The second motor 10 can be started according to the different sizes of the roll. The second motor 10 drives the two threaded rods 21 to rotate synchronously through the first pulley 17 and the first belt 18. Since the movable seat 20 is threadedly connected to the threaded rod 21 and slidably connected to the rectangular groove 22, when the threaded rod 21 rotates, the movable seat 20 will move horizontally along the rectangular groove 22, thereby realizing the synchronous adjustment of the two movable seats 20.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
