Zusammenfassung:The utility model relates to a paper roll label positioning device which comprises a conveying mechanism, a first detection mechanism, a second detection mechanism and a control mechanism. The first detection mechanism is arranged on one side of the conveying mechanism and used for detecting paper roll labels. The second detection mechanism is arranged on one side of the conveying mechanism, the second detection mechanism is located above the first detection mechanism, the second detection mechanism is used for detecting the paper roll label, and the height difference between the second detection mechanism and the first detection mechanism is larger than the width or length of the paper roll label; the control mechanism is used for receiving detection signals fed back by the first detection mechanism and the second detection mechanism and controlling starting and stopping of the conveying mechanism. According to the paper roll label positioning device, the problem that deviation of the paper roll label is not
