The utility model discloses a theory of operation does: after the cloth is completely wound on the winding shaft, the detection switch is started and controls the rotating motor connected with the detection switch through an electric signal to rotate for a certain angle (namely, the opening of the U-shaped groove formed in the clamping block faces back to the roll changing mechanism). Then the cutting mechanism acts to cut the cloth. And then, a horizontal telescopic cylinder in the roll changing mechanism acts to drive the vertical supporting plate to horizontally move to a U-shaped clamping groove formed in the upper part of the vertical supporting plate to be clamped into a rotating shaft of the winding roll, and then the horizontal telescopic cylinder continues to act to push out the winding shaft from the clamping block. Then, vertical telescopic cylinder descends to one end distance (wait to change the rolling axle can with the grip block collision when passing through the grip block below can), and horizontal telescopic cylinder continues to stretch out forward afterwards to drive the rolling axle that the rolling cloth was accomplished and the rolling axle that waits to change and move forward simultaneously, when removing the back that targets in place (waiting to change the rolling axle and crossing the grip block), horizontal telescopic cylinder stops stretching out forward, and the workman will take off the rolling axle that has changed this moment. Then, vertical telescopic cylinder upwards stretches out to be in same level height to the U type recess in rolling axle and the grip block of treating the change, and the telescopic link of horizontal telescopic cylinder is toward retracting this moment, pushes the rolling axle into to the U type recess of grip block afterwards. Then, the telescopic rod of the horizontal telescopic cylinder extends forwards for a distance and then is separated from the contact with the winding shaft, then the vertical telescopic cylinder contracts downwards, the horizontal telescopic cylinder also contracts simultaneously so as to enable the roller changing mechanism to return to the initial position, and at the moment, the replacement action of the winding shaft is completed once. When the rolling shaft needs to be replaced again, the rolling shaft to be replaced is placed in the U-shaped clamping groove on one side, deviating from the bearing mechanism, of the vertical supporting plate, and then the operation is repeated.

Has the advantages that: the utility model discloses an above-mentioned structure, very big promotion the rolling axle with the degree of automation of trading the in-process, and then reduced the intensity of labour when workman changes the rolling axle and promoted the change efficiency.
