[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A tensile testing device for filter membrane production includes a base plate 1. A first strip groove 16 is formed at the top of the base plate 1. A fixed seat 10 is installed on the upper surface of the base plate 1 at one end of the first strip groove 16. A first clamping assembly is provided on one side of the fixed seat 10. A moving assembly is connected to the other side of the fixed seat 10. A bearing assembly is installed on the moving assembly. A connecting block 12 is installed on the bearing assembly. A tensile sensor 20 is installed on one side of the connecting block 12. One end of the tensile sensor 20 is connected to a second clamping assembly. A control host 13 is installed on the upper surface of the base plate 1. The control host 13 integrates a PLC controller, control buttons, and a display screen.

[0023] The first clamping assembly includes a first L-shaped support rod 8 fixed to the upper surface of the base plate 1 and located on one side of the fixed seat 10. A first telescopic cylinder 7 is installed on the lower surface of the horizontal section of the first L-shaped support rod 8. A first L-shaped clamping strip 9 is connected to the lower end of the first telescopic cylinder 7. The first telescopic cylinder 7 is pushed down by the control host 13 to fix one end of the filter membrane to the fixed seat 10.

[0024] The moving component includes a servo motor 18 fixed to the upper surface of the base plate 1. The output end of the servo motor 18 is connected to a threaded rod 14. One end of the threaded rod 14 is rotatably connected to the fixed seat 10 through a bearing. A moving block 17 is screwed onto the threaded rod 14. The bottom end of the moving block 17 is slidably engaged with the first strip groove 16.

[0025] The supporting component includes a support plate 2 fixed to the upper end of the movable block 17, and a second strip groove 15 is provided on the upper end of the support plate 2 along its axial direction.

[0026] The filter membrane is clamped at both ends using a first clamping assembly and a second clamping assembly, respectively. The operator sets the stretching speed and displacement via the control unit 13, and starts the servo motor 18. The servo motor 18 drives the threaded rod 14 to rotate, and the moving block 17 moves linearly along the first slot 16, thereby causing the second clamping assembly to stretch the filter membrane sample relative to the first clamping assembly. During the stretching process, the tension sensor 20 collects real-time tension data and transmits it to the data processing module of the control unit 13. The data processing module analyzes and processes the data to calculate parameters such as the tensile strength and elongation at break of the filter membrane. After the test is completed, the test data and analysis results are displayed on the screen, and the operator can print a test report using a printer.

[0027] Example 2 is an optimization based on Example 1. Specifically, the second clamping assembly includes a second L-shaped support rod 4 connected to one end of the tension sensor 20. A second telescopic cylinder 5 is installed on the lower end of the horizontal section of the second L-shaped support rod 4. A second L-shaped locking strip 3 is connected to the lower end of the second telescopic cylinder 5. A slider 19 is connected to the lower end of the second L-shaped support rod 4. A support rod 11 is fixed to the upper end of the slider 19 and below the second L-shaped locking strip 3. The lower end of the slider 19 is slidably engaged with the second strip groove 15 to ensure that the slider 19 moves along the second strip groove 15. Anti-slip textures 6 are provided on the upper end surfaces of the fixed seat 10 and the support rod 11.

[0028] By controlling the second telescopic cylinder 5 to push the second L-shaped support rod 4 downward, the other end of the filter membrane can be fixed to the support rod 11 by the second L-shaped support rod 4. The anti-slip texture 6 can increase the friction when fixing the filter membrane and prevent the filter membrane from falling off during the stretching process.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
