A strip winding machine comprises a transmission device and a winding device which is driven by the transmission device, wherein the winding device comprises a frame, a lead-in mechanism, a bending roll group, a carrier roller group and a coil stripping mechanism, and the lead-in mechanism consists of double vertical-roll groups are arranged at two sides of a rolling entrance of the frame and a pair of lead-in roll groups which are horizontally arranged; the bending roll group consists of a left lower roll, a right lower roll and an upper press roll, and the left lower roll, the right lower roll and the upper press roll are arranged in a delta shape; the carrier roller group consists of a right carrier roller group, a left carrier roller group and a pair of guide plates which are arranged at two sides of the frame and are provided with a guide roller, wherein the right carrier roller group and the left carrier roller group are arranged above two sides of the upper press roll; and the coil stripping mechanism consists of a front coil stripping mechanism which is arranged at the rolling entrance and a rear coil stripping mechanism which is arranged at a rolling exit, and each coil stripping mechanism is a swinging mechanism which is driven by an oil cylinder. Since the winding device is provided with the lead-in mechanism which consists of double vertical-roll groups and the right carrier roller group, the bending roll group which is in a delta shape and the winding roller group which consists of the right carrier roller group, the left carrier roller group and the guide plate with the guide roller, the leading-in of the strip is more correct, the pre-bending curvature is more favorable for the rolling of the following rolling, at the same time the rolling is tight, two ends of the strip are smooth, and in addition, and the strip coil after being wound can be conveniently unloaded onto a coil storage cart so as to be transported to the next procedure.
