AI Technical Summary
Existing paper folding endurance testing devices are prone to causing paper tilting during clamping, affecting test results, and the tension adjustment process is cumbersome, requiring improvement.
A folding endurance testing device was designed, which uses a T-shaped guide rail and a tension adjustment assembly. The position of the tension clamp is adjusted by the slide to keep the paper vertical, and the tension is quickly adjusted by the spring and fastening bolt.
This method ensures that the paper remains perpendicular during testing, reducing testing errors and improving the convenience and efficiency of tension adjustment.
