Tension adjusting device for waterproof roll production

The utility model relates to the technical field of waterproof roll production lines, and provides a tension adjusting device for waterproof roll production, which comprises a base, moving rails are fixedly mounted at two ends above the base, and relative moving mechanisms for adjusting tension rollers are arranged in the moving rails. The relative moving mechanism comprises a bidirectional moving lead screw which is rotationally connected to the center of the interior of the moving rail and used for adjusting the distance between the moving tables. During use, a bidirectional moving screw rod can be driven to rotate at the same time through the cooperation effect of a first gear, a toothed chain, a second gear and a rotating motor, and the bidirectional moving screw rod penetrates through the internal structure of a moving table to drive the moving table and a mounting frame to move relatively, so that the distance between tension rollers is adjusted; and the purpose of adjusting the tension is achieved by a
