The utility model discloses a winding and pressing roll mechanism and a lithium battery winding machine. The winding and pressing roll mechanism comprises a connecting rod and a rotating central axis set in the middle of the connecting rod; one end of the connecting rod is a swing arm of the pressing roll, and the other end of the connecting rod is a counterweight swing arm, and the counterweight block is connected; the pressing roll and the counterweight block can rotate around the rotating central axis, and the counterweight block rotates around the rotating central axis. The moment generated by the center is greater than that of the roller. The press roll and counterweight block are set at both ends of the connecting rod respectively, and can rotate around the rotating central axis in the middle of the connecting rod, thus forming a rotating mechanism of the connecting rod. The moment generated by the counterweight block around the rotating center is greater than the moment produced by the press roll, so that the press roll always produces pressure on the coil, thus realizing the rolling belt effect. The structure of the utility model is pure mechanical structure without electric power control. Compared with the existing technology, the structure of the utility model is simpler and has better stability, greatly reduces the manufacturing and maintenance costs, and is suitable for large-scale production.
