[0039] In this way, for a winding device with a sliding door at the entrance involved in the present utility model, during use, the left side of the stack abuts against the sliding door 2, thereby guiding the stack correctly. Since the conveying direction of the conveying mechanism 4 is perpendicular to the plane where the sliding door 2 is located, and the stack is in a cuboid shape, after the stack is guided correctly, the front and rear sides of the stack are parallel to the conveying direction of the conveying mechanism 4, thus facilitating the winding mechanism 3 to wind the stack.

[0040] When the winding mechanism 3 is winding, a packaging film can be arranged on the winding rolling frame 32, and the winding driving assembly 31 drives the winding rolling frame 32 to rotate, thereby driving the packaging film to rotate around the stack, so that when the stack moves, the side of the stack is wound by the packaging film multiple times, thereby realizing the packaging of the stack.

[0041] Optionally, a horizontal guide rod 11 is arranged on the main bracket 1 or an independent bracket beside the main bracket, a horizontal guide block 21 is arranged on the sliding door 2, and a guide hole for the horizontal guide rod 11 to pass through is arranged on the horizontal guide block 21.
