[0002] Rubber products play an indispensable role in industrial production and daily life. The stability and reliability of their performance have a crucial impact on the overall quality of the products. Therefore, it is essential to attach great importance to the quality control of rubber products to ensure that their performance reaches the optimal level to meet various application requirements.

[0003] However, traditional tensile testing of rubber products mainly focuses on the tensile properties in the vertical direction. Although this testing method can obtain basic performance indicators such as tensile strength and elongation at break of rubber products in a specific direction, it cannot fully reflect the torsional and oblique tensile properties of rubber products at different angles.

[0004] Therefore, since the traditional tensile tests for rubber products mainly focus on the vertical direction and cannot fully reflect their torsional and oblique tensile properties at different angles, a continuous tensile device for rubber products can be designed to achieve comprehensive testing of the torsional and oblique tensile properties of rubber products at different angles. Compared with the traditional tensile test that only focuses on the vertical direction, this improves the comprehensiveness and accuracy of the test. Utility Model Content

The first bearing seat 10 is a component for supporting and fixing the clamping plate 11. The clamping plate 11 is a component for directly clamping the rubber product. The surface of the clamping plate 11 is textured to increase the friction between it and the rubber product and prevent the rubber product from sliding or falling off during the stretching process. The second rotary motor 12 is a power source for driving the turntable 14 to rotate. It drives the support shaft 13 to rotate, thereby driving the turntable 14 to rotate.

[0024] Please see Figure 1 and Figure 4 In this embodiment, the inclined cable assembly includes a vertical plate 15. One end of the base 1 is fixedly connected to the vertical plate 15. A second bearing seat 16 is provided on the surface of the vertical plate 15. A first rotating shaft 17 is rotatably connected inside the second bearing seat 16. One end of the first rotating shaft 17 is fixedly connected to a support plate 18. One end of the support plate 18 is fixedly connected to a second rotating shaft 19. A bracket 20 is provided at the upper end of the base 1. A third rotary motor 21 is installed at the upper end of the bracket 20. The output shaft of the third rotary motor 21 is connected to the second rotating shaft 19 via a coupling. The vertical plate 15... It is the support structure of the inclined tension assembly. It is vertically fixed to one end of the base 1. The second bearing seat 16 is a component used to install and support the first rotating shaft 17. One end of the first rotating shaft 17 is fixedly connected to the support plate 18. By rotating the first rotating shaft 17, the angle of the support plate 18 can be changed. The support plate 18 is used to support and fix the second rotating shaft 19. The second rotating shaft 19 is a component that connects the third rotary motor 21 and the support plate 18 to ensure that the third rotary motor 21 can smoothly drive the inclined tension assembly to work, thereby performing inclined tension tests on rubber products.

[0025] Please see Figure 1 and Figure 5In this embodiment, the stretching module includes a No. 3 bearing seat 22. Two No. 3 bearing seats 22 are symmetrically arranged on the upper end of the support plate 18. A No. 1 threaded rod 23 is rotatably connected inside the No. 3 bearing seat 22 on the left, and a No. 2 threaded rod 24 is rotatably connected inside the No. 3 bearing seat 22 on the right. The No. 1 threaded rod 23 is connected to the output shaft of the No. 1 rotary motor 4 via a coupling. The No. 1 threaded rod 23 and the No. 2 threaded rod 24 are connected via a transmission structure. A stretching plate 25 is threadedly connected to the outer walls of the No. 1 threaded rod 23 and the No. 2 threaded rod 24. An upper clamp is provided at the lower end of the stretching plate 25. The transmission structure includes a drive wheel 26. The drive wheel 26 is fixedly connected to the outer wall of the No. 1 threaded rod 23, and a driven wheel 27 is fixedly connected to the outer wall of the No. 2 threaded rod 24. A belt 28 is rotatably connected to the drive wheel 26 and the driven wheel 27. The lower end of the crossbeam of the gantry 3... A guide rod 29 is fixedly connected to the upper end of the support plate 18. The outer wall of the guide rod 29 is slidably connected to the tension plate 25. The third bearing seat 22 is a component used to install and support the first threaded rod 23 and the second threaded rod 24. When the first rotary motor 4 drives the first threaded rod 23 to rotate, the driving wheel 26 drives the driven wheel 27 to rotate through the belt 28, thereby realizing the synchronous rotation of the second threaded rod 24. The outer walls of the first threaded rod 23 and the second threaded rod 24 are threadedly connected to the tension plate 25. The tension plate 25 is a component used to stretch rubber products. Through the principle of threaded transmission, when the first threaded rod 23 and the second threaded rod 24 rotate together, the tension plate 25 will move along the axial direction of the first threaded rod 23 and the second threaded rod 24. The guide rod 29 is used to guide the lifting and lowering movement of the tension plate 25, thereby preventing the tension plate 25 from shaking when moving.

[0026] In the workflow, the two ends of the rubber product are first firmly clamped by the upper and lower clamps respectively. The specific operation is as follows: rotate the knob 9 to make the screw 8 screw in, which drives the clamping plate 11 to fit tightly against the rubber product, thereby completing the fixing step.

[0027] Subsequently, a straight-pull test was conducted. Rotary motor 4 was started, which drove threaded rod 23 and drive wheel 26 to rotate. Drive wheel 26 was linked to driven wheel 27 via belt 28, causing threaded rod 24 to rotate synchronously. Based on the thread transmission principle, tension plate 25 began to rise. By observing the reading on scale 5, a straight-pull test was carried out on the rubber product.

[0028] If a slant test is required, start the No. 3 rotary motor 21. The No. 3 rotary motor 21 drives the support plate 18 to rotate. By observing the reading on the angle ruler 6, the tilt angle can be accurately determined. Then, start the No. 1 rotary motor 4 again to begin the slant test.

[0029] While conducting straight and oblique pull tests, the second rotary motor 12 can be started. The second rotary motor 12 drives the support shaft 13 to rotate, which in turn drives the turntable 14 and the lower clamp to rotate, thereby realizing the torque test of the rubber product.

[0030] Through the above steps, this solution integrates a rotating component and a diagonal tension component, enabling comprehensive testing of the torsional and diagonal tensile properties of rubber products at different angles. Compared to traditional tensile testing that only focuses on the vertical direction, this solution improves the comprehensiveness and accuracy of the test. By precisely controlling the rotation and diagonal tension actions, it not only enhances the accuracy of the test but also effectively improves the overall testing efficiency, providing more reliable data support for the quality assessment of rubber products. This solves the problem that traditional tensile testing of rubber products mainly focuses on the vertical direction and cannot fully reflect their torsional and diagonal tensile properties at different angles.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
