The invention provides an insulation paper traction device for a transformer winding device. The insulation paper traction device comprises a base, a first supporting rack and a second supporting rackwhich are arranged opposite to each other in a spaced manner on the base, a rotary shaft which can be rotatably arranged between the first supporting rack and the second supporting rack, a compressing mechanism which is arranged between the first supporting rack and the second supporting rack and is located below the rotary shaft and a locking mechanism which is arranged between the first supporting rack and the compressing mechanism. An insulation paper roll winds the rotary shaft, the compressing mechanism can move up and down, the compressing mechanism moves upward to lean against the insulation paper roll so as to press the insulation paper roll and moves downward to release the insulation paper roll, so that the insulation paper roll rotates normally; the locking mechanism is used for locking the compressing mechanism which moves downward to a certain position so as to prevent the compressing mechanism from moving upward. The insulation paper traction device provided by the invention can prevent the insulation paper roll from rotating during paper cutting, so that the paper cutting operation is facilitated, and the work efficiency is increased.
