AI Technical Summary
Existing plastic film tensile testing devices lack positioning structures, which may cause the plastic film to tilt during testing, resulting in the tensile force line not being consistent with the actual stretching direction, thus reducing the accuracy of the test results.
The second bidirectional threaded rod in the positioning mechanism drives the positioning plate to move in the adjustment groove, which in turn drives the clamping plate to move in the clamping groove, thereby limiting the front-to-back and left-to-right position of the plastic film and ensuring that the line of action of the tensile force is consistent with the actual stretching direction.
It improves the accuracy of test results and reduces operational hazards, preventing injury to test personnel from sudden breakage of the plastic film during stretching.
