Therefore, there is an urgent need for a film bag tensile testing machine for testing the elasticity, load-bearing capacity, and toughness of base fabrics to solve the above technical problems.

A lower support frame 5 is connected to the top of the lower support base 4. First clamping cylinders 6 are installed on the left and right side walls of the lower support frame 5. One end of each of the two first clamping cylinders 6 passes through the left and right side walls of the lower support frame 5 and is connected to a lower clamping block 9. A guide opening 18 is opened in the middle of the front face of the hollow support column 19, and two support seats 1 are installed inside the hollow support column 19. 2. A screw 11 is connected between the two support seats 12. A nut seat 14 is connected to the screw 11 via a screw nut 13. A motor mounting frame 17 is connected to the inner rear end face of the hollow support column 19. A motor 16 is installed inside the motor mounting frame 17. The lower end of the screw 11 passes through the support seat 12 and is connected to the motor 16 via a coupling 15. The front end of the nut seat 14 passes through the guide opening 18 and is connected to the upper support base 21.

One end of each of the two second clamping cylinders 8 passes through the left and right side walls of the upper support frame 7 and is connected to an upper clamping block 10. A scale line 20 is provided on the left edge of the front end face of the hollow support column 19. A pointer 22 is connected to the right side wall of the upper support base 21.

[0027] The working principle and usage process of this utility model are as follows: First, during the test, the lower end of the test base fabric is placed between two lower clamping blocks 9, and the upper end of the base fabric is placed between two upper clamping blocks 10. Then, the two first clamping cylinders 6 are activated to drive the two lower clamping blocks 9 to clamp and fix the lower end of the base fabric. The two second clamping cylinders 8 are activated to drive the two upper clamping blocks 10 to clamp and fix the upper end of the base fabric, thereby achieving rapid clamping of the test base fabric and improving the testing efficiency. Afterwards, the motor 16 is started and drives the screw 11 to rotate through the coupling 15. The rotating screw 11 drives the nut seat 14 to move upward along the guide opening 18 through the lead screw nut 13, thereby conducting tensile tests on elasticity, load-bearing capacity, and toughness. Through the set pointer 22 and scale line 20, the length of the base fabric stretched during the tensile test can be observed intuitively, making it easy to record.
