Stable unwinding device for interlayer paper

The utility model provides a stable unwinding device for interlayer paper. The stable unwinding device comprises a vertical frame, a rotating shaft, a limiting block and a driving mechanism, the two ends of the rotating shaft are detachably installed on the vertical frame so that the middle of the rotating shaft can be suspended. The limiting block slidably sleeves the rotating shaft; the driving mechanism can adjust the position of the limiting block on the rotating shaft. According to the utility model, the rotating shaft is detached from the vertical frame, so that the rotating shaft can be inserted into a paper tube in the middle of an isolation paper roll, then the limiting block is sleeved on the rotating shaft, the two ends of the rotating shaft are re-mounted on the vertical frame, and then the driving mechanism is controlled to act and drives the limiting block to slide on the rotating shaft; the limiting block pushes the isolation paper roll to slide on the rotating shaft, so that one end of the pap
