Automatic roll changing method for horizontal cylinder paper winding machine at medium-low speed

The invention relates to an automatic roll changing method of a medium-low speed horizontal cylinder paper winding machine, which comprises the following steps of: utilizing an inclined cam, a paper winding cylinder, a paper breaking device, a linear guide rail and a paper winding machine of a main arm, and realizing smooth movement and roll changing process of a paper roll to be changed through an auxiliary arm device. The method comprises the specific steps that a paper roller to be replaced is placed in a paper containing groove of an oblique cam, an auxiliary arm moves to take out the paper roller to be replaced, the paper roller is moved to a linear guide rail, a paper web is cut off, and then new paper is wound. According to the automatic roll changing method of the medium-low-speed horizontal cylinder paper winding machine, the whole roll changing process is automatically completed, manual participation is not needed, the labor intensity is greatly reduced, the roll changing method simplifies operation
