Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic production technology, and in particular to a device for testing the tensile strength of rubber and plastic strips. Background Technology

[0002] Rubber and plastics are a collective term for the rubber and plastics industries. They are both byproducts of petroleum and share the same origin. However, their physical properties and uses differ during the manufacturing process. Rubber is widely used in tires, while plastics have become increasingly ubiquitous due to technological advancements, market demands, and diverse applications, making them indispensable in daily life. Because of their unique chemical structure, rubber and plastic materials are flammable and produce molten droplets during combustion. Traditional rubber and plastic strips often break during equipment testing. Since the testing equipment itself lacks protective structures, the broken strips can easily damage the equipment, reducing its lifespan and overall performance. Utility Model Content

[0008] The movable component includes two movable blocks fixedly connected to the surface of the assembly horizontal plate. A movable shaft is rotatably connected between the two movable blocks. A movable cover is fixedly sleeved on the outer wall of the movable shaft. One end of the movable shaft passes through one of the movable blocks and is fixedly connected to a movable disc. A connecting component for adjusting the rotation of the movable disc is connected to the top of the assembly horizontal plate.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a connecting block that is fixedly connected to the top of the assembly cross plate. A connecting shaft is rotatably connected through the side wall of the connecting block.

[0023] Reference Figure 1-3 This utility model provides a device for testing the tensile strength of rubber and plastic strips, including a testing platform 1. Two mounting support plates 2 are fixedly connected to the top of the testing platform 1. A mounting cross plate 3 is fixedly connected between the two mounting support plates 2. One of the mounting support plates 2 has a scale groove on its surface. A first sleeve block 4 and a second sleeve block 6 are movably fitted onto the outer wall of the mounting support plate 2. A first cross plate 5 is fixedly connected between the two first sleeve blocks 4, and a second cross plate 7 is fixedly connected between the two second sleeve blocks 6. Adjusting recesses 8 are fixedly connected to opposite sides of the first cross plate 5 and the second cross plate 7. Adjusting bolts 9 are threaded through and threaded onto both sides of the outer wall of the adjusting recesses 8. One end of the adjusting bolt 9 is rotatably connected to an adjusting clamping plate 10, and the other end is fixedly connected to an adjusting rotating block 11. A driving assembly is connected to the top of the mounting cross plate 3, which adjusts the movement of the first cross plate 5 and the second cross plate 7. Figure 1 and Figure 2 The drive assembly includes a drive motor 12 fixedly connected to the top of the assembly horizontal plate 3. A drive bidirectional screw 13 is fixedly connected to the output end of the drive motor 12. The end of the drive bidirectional screw 13 passes through the assembly horizontal plate 3 and is rotatably connected to the inspection table 1. The first horizontal plate 5 and the second horizontal plate 7 are both threadedly connected to the drive bidirectional screw 13. The drive motor 12 drives the drive bidirectional screw 13 to rotate.

[0024] The front and rear sides of the assembly plate 3 are connected to movable components, see reference. Figure 2 The movable component includes two movable blocks 14 fixedly connected to the surface of the assembly cross plate 3. A movable shaft 15 is rotatably connected between the two movable blocks 14. A movable cover 16 is fixedly sleeved on the outer wall of the movable shaft 15. One end of the movable shaft 15 passes through one of the movable blocks 14 and is fixedly connected to a movable disc 17. The movable cover 16 serves to prevent the rubber material from breaking and scattering.

[0025] The top of the assembly horizontal plate 3 is connected to a connecting component with an adjustable movable disc 17 for rotation, see reference. Figure 1 and Figure 3The connecting assembly includes a connecting block 18 fixedly connected to the top of the assembly horizontal plate 3. A connecting shaft 19 is rotatably connected through the side wall of the connecting block 18. A first connecting disc 20 and a second connecting disc 21 are fixedly sleeved on the outer side wall of the connecting shaft 19. The movable disc 17 is driven by a belt to its corresponding first connecting disc 20 or second connecting disc 21. A connecting worm gear 22 is fixedly connected to one end of the connecting shaft 19. Two connecting support blocks 23 are fixedly connected to the top of the assembly horizontal plate 3. A connecting motor 24 is fixedly connected to the surface of one of the connecting support blocks 23. A connecting worm 25 is fixedly connected to the output end of the connecting motor 24. The end of the connecting worm 25 passes through one of the connecting support blocks 23 and is rotatably connected to the other connecting support block 23. The connecting worm 25 meshes with the connecting worm gear 22. The connecting motor 24 drives the connecting worm 25 to rotate.

[0026] Working principle: In use, the two ends of the rubber / plastic strip to be tested are placed between two of the adjusting clamping plates 10 and the other two adjusting clamping plates 10, respectively. Then, the adjusting block 11 is rotated, causing the adjusting bolt 9 to rotate. This causes the adjusting bolt 9 to cause the adjusting clamping plate 10 to press against the rubber material. Then, the connecting motor 24 is started, which drives the connecting worm wheel 22 on the connecting worm 25 to rotate. Then, the connecting worm wheel 22 also drives the first connecting disc 20 and the second connecting disc 21 on the connecting shaft 19 to rotate. Since the first connecting disc 20 and the second connecting disc 21 are connected to their corresponding movable discs 17 by belts, the movable shaft 15 on the movable disc 17 also drives the movable cover 16 to flip. This causes the movable cover 16 to flip towards the testing table 1 for protection, ensuring the adjustment and protection effect.

[0027] Then, the drive motor 12 is started, which drives the drive double screw 13 to rotate, causing the first horizontal plate 5 and the second horizontal plate 7 to move away from each other along the direction on the drive double screw 13. Then, the first set of blocks 4 and the second set of blocks 6 on the first horizontal plate 5 or the second horizontal plate 7 also move along the direction on the mounting support plate 2, thereby guiding the first horizontal plate 5 and the second horizontal plate 7. The tension of the first horizontal plate 5 or the second horizontal plate 7 is detected by the scale groove on one of the mounting support plates 2 to ensure the adjustment and detection effect.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
