Abnormality detection mechanism applied to adhesive tape slitting machine

The utility model discloses an anomaly detection mechanism applied to an adhesive tape slitting machine, which comprises a rack, a wind-up roller is movably arranged at the bottom end in the rack, a width detection mechanism is arranged on one side of the input end of the wind-up roller, the width detection mechanism is fixedly arranged on the rack, and the width detection mechanism can obtain the width of a slitting adhesive tape in real time. When the width data is abnormal, an alarm is given out immediately, operation is stopped, a worker waits for adjustment and maintenance, then the situation that the width is not uniform when the adhesive tape is split is avoided, and the adhesive tape winding quality is improved; a cutter shaft is further fixedly arranged at the top end of the rack, a plurality of blades are evenly arranged and detachably arranged below the cutter shaft in the axial direction, and a vibration sensor is arranged on one side of each blade; when the vibration sensor detects that the blade
