Automatic production line for square toilet paper

The invention relates to an automatic production line for square toilet paper. Paper rolls on a first paper roll supporting mechanism and a second paper roll supporting mechanism are knurled through a knurling transmission mechanism and are stacked together to be conveyed to a winding cutting mechanism; the paper rolls are wound through the winding cutting mechanism and are cut after being wound, the cut toilet paper is conveyed to a fixed conveying line through a movable conveying line, and the paper rolls are conveyed through the fixed conveying line to a first paper cutting mechanism and a second paper cutting mechanism to be cut; then the paper rolls are conveyed to a packaging machine through a filtering conveying line to be packaged; and finally the packaged finished product toilet paper is conveyed out through a recovery conveying line. By means of the automatic production line for the square toilet paper, operation is convenient, the toilet paper can be automatically machined, the production efficiency is high, the quality of the produced toilet paper is high, the marketable development demand is met, and the higher practicability and the higher promotional value are achieved.
