When using the film tensile strength testing device to test the tensile strength of the produced film, after placing the film to be tested into the impurity groove 14, the position of the film is fixed by the clamping assembly. Then, when the adjusting assembly moves, the position of the bar-shaped frame 2 will be adjusted. When the two bar-shaped frames 2 move in opposite directions, the two sides of the film will be pulled to move in opposite directions, thereby testing the tensile strength borne by the film. When adjusting the film tensile strength testing method as needed, the electric telescopic rod 24 is made to work to push the square plate 22 to move, and then the arc plate 23 will be pushed to move upward. When the arc plate 23 moves upward, the middle position of the film will be pushed to move upward, thereby testing the tensile strength of the film in another way, improving the flexibility of the film tensile strength testing device and enabling the tensile strength borne by the film to be tested according to different requirements.

[0023] Please refer to Figure 1 , guide rods 5 are fixedly installed inside the bar-shaped grooves 4, and the guide rods 5 penetrate through the connecting blocks 3. When the connecting blocks 3 move, the guide rods 5 guide the connecting blocks 3 to move smoothly.

One end of the connecting block 3 is fixedly connected to the top of the support plate 11. A guiding assembly is arranged inside the square box 7. When the driving motor 8 works, it will drive the threaded lead screw 9 to rotate. When the threaded lead screw 9 rotates, it will cause the threaded ring 10 to move.

[0026] Please refer to Figure 2 , the guiding assembly includes a guiding ring 12 and a guiding rod 13. The guiding ring 12 is fixedly installed at both ends of the support plate 11. The guiding rod 13 passes through the guiding ring 12, and the guiding rod 13 is fixedly connected to the inner wall of the square box 7. When the support plate 11 moves, it will drive the guiding ring 12 to slide on the guiding rod 13. When the guiding ring 12 moves, it cooperates with the guiding rod 13 to guide and limit the support plate 11, so that the support plate 11 moves smoothly.

[0027] Please refer to Figure 1 and Figure 3 , the clamping assembly includes a threaded cylinder 17, a threaded rod 18, and a pressing plate 16.

A plurality of strip-shaped plates 15 are arranged in an array inside the groove 14, and the length of the strip-shaped plates 15 is equal to the length of the groove 14. When the clamping assembly limits and clamps the film, after placing the film between the grooves 14, rotate the threaded rod 18. The threaded cylinder 17 will cause the threaded rod 18 to move. When the threaded rod 18 moves, it will push the pressing plate 16 to move. After the pressing plate 16 moves downward and contacts the surface of the film, it will limit and clamp the position of the film. A clamping groove corresponding to the strip-shaped plate 15 is arranged at the bottom of the pressing plate 16. The cooperation between the strip-shaped plate 15 and the clamping groove on the pressing plate 16 will improve the clamping stability of the film and prevent the film from accidentally falling during the clamping test.

[0028] Please refer to Figure 3 , two limiting cylinders 19 are symmetrically arranged inside the strip-shaped frame 2. A limiting rod 20 is inserted into the limiting cylinder 19, and the bottom end of the limiting rod 20 is fixedly connected to the top of the pressing plate 16.

[0029] Working principle: When testing the tensile strength of the produced film using the film tensile testing device, after placing the film to be tested inside the impurity groove 14, the position of the film is fixed by the clamping assembly. When the clamping assembly limits and clamps the film, after placing the film between the grooves 14, rotate the threaded rod 18, and the threaded barrel 17 will cause the threaded rod 18 to move. When the threaded rod 18 moves, it will push the pressure plate 16 to move. After the pressure plate 16 moves downward and contacts the surface of the film, it will limit and clamp the position of the film. A card slot corresponding to the long strip plate 15 is provided at the bottom of the pressure plate 16. The cooperation between the long strip plate 15 and the card slot on the pressure plate 16 will improve the stability of clamping the film. Then, driving the motor 8 to work will drive the threaded lead screw 9 to rotate. When the threaded lead screw 9 rotates, it will cause the threaded ring 10 to move. When the threaded ring 10 moves, it will drive the support plate 11 to move. When the support plate 11 moves, it will drive the connecting block 3 to move, and the position of the strip-shaped frame 2 will be adjusted. When the two groups of strip-shaped frames 2 move in opposite directions, they will pull the two sides of the film to move in opposite directions, thereby testing the tensile force borne by the film. When adjusting the film tensile testing method as needed, making the electric telescopic rod 24 work will push the square plate 22 to move, and then will push the arc-shaped plate 23 to move upward. When the arc-shaped plate 23 moves upward, it will push the middle position of the film to move upward, and thus the tensile force of the film can be tested by another method, improving the flexibility of the film tensile testing device and enabling the tensile force borne by the film to be tested according to different requirements.
