Stretching detector for adhesive tape production

The invention relates to the field of stretching detection, in particular to a stretching detector for adhesive tape production, which comprises a detector, a connecting frame, a clamping block and the like, the number of the detectors is multiple, and the detectors are distributed in a rectangular shape. A plurality of connecting frames are mounted on the rear detectors; and a clamping block for fixing an adhesive tape is arranged on each connecting frame. The front side and the rear side of an adhesive tape lapped on the stretching roller are blocked and limited through the limiting blocks and the limiting rings, the adhesive tape is prevented from sliding front and back on the stretching roller and shifting when being pulled, the test result of the adhesive tape is prevented from being affected, the two ends of the adhesive tape are fixed through the clamping blocks, and the test efficiency is improved. Then the moving distances of the stretching rollers on the left side and the right side are controlled r
