The rewinding machine as claimed in claim 1, wherein the winding mechanism further comprises a pressing roller and a second driving device, the pressing roller is rotatably mounted on the winding frame, the pressing roller is located between the second roller and the winding shaft and is parallel to the winding shaft, the second driving device is used for driving the pressing roller to rotate, the coil passes through the first roller, the second roller and the pressing roller in sequence after being unwound by the unwinding shaft and then is wound by the winding shaft, and the pressing roller is used for clinging the coil on the winding shaft to drive the winding shaft to rotate.

6. The rewinding machine as claimed in claim 5, wherein the press roller comprises a press roller body and a press roller mounting portion, two ends of the press roller mounting portion are fixedly mounted to the top end of the winding rack through two second bearing seats respectively, one end of the press roller mounting portion is connected with the press roller body, and the other end of the press roller mounting portion is connected with the second driving device.

7. The rewinding machine as claimed in claim 6, wherein the second driving device includes a second driving motor and a second synchronous belt transmission mechanism fixedly mounted to the rewinding machine frame, and one end of the roller mounting portion far away from the roller body is connected to the second driving motor through the second synchronous belt transmission mechanism.

8. The rewinding machine according to claim 5, wherein the winding shaft comprises a winding shaft body and a winding shaft mounting portion, one end of the winding shaft mounting portion is connected with the winding shaft body, two ends of the winding shaft mounting portion are fixedly mounted on a mounting plate through two third bearing seats respectively, the mounting plate is located below the winding shaft mounting portion and is parallel to the winding shaft mounting portion, the mounting plate is slidably mounted on the top end of the winding rack, the mounting plate can slide along the top end of the winding rack towards the direction close to or away from the pressing roller, and therefore the winding shaft can be driven to move towards the direction close to or away from the pressing roller.

9. The rewinding machine as claimed in claim 8, wherein the winding mechanism further comprises a driving cylinder fixedly mounted to the winding frame, a connecting plate is disposed on a side of the mounting plate away from the pressing roller, the connecting plate is connected to the driving cylinder, and the driving cylinder is configured to drive the connecting plate to move towards or away from the pressing roller relative to the winding frame, so as to drive the mounting plate to slide towards or away from the pressing roller.

10. The rewinding machine as claimed in claim 1, characterized in that both said unwinding and winding shafts are inflatable shafts.
