[0012] 1. The tearing resistance test device of the composite film rotates a rotating rod connected in the inner cavity of the lifting plate, and a driven gear is arranged on the outer wall of the rotating rod. When the test film needs to be rotated and torn, the driving motor drives the driving gear to rotate, so that the rotating rod drives the fixed seat below to rotate, thereby realizing the left and right rotation tearing of the composite film, thereby obtaining better test results.
