This utility model relates to the technical field of testing devices for label production, and discloses a label production testing device that is easy to position. It includes a control console, a bidirectional screw rotatably connected between two side plates, two sliders threadedly connected to the outer surface of the bidirectional screw, a vertical plate on the upper surface of the sliders, and two positioning blocks slidably connected to the outer surface of the unwinding roller. This utility model works by first placing the label roll onto the unwinding roller, then having one end abut against one of the positioning blocks, and then moving the other positioning block to fit against the other end of the label roll. The unwinding roller is then mounted on the vertical plate. A motor is started to drive the bidirectional screw to rotate, causing the sliders on both sides to slide synchronously towards the center along the slide rail.
