The body assembly includes a base, two clamping plates and two positioning cones. The two clamping plates are arranged inside the base, and the two positioning cones are rotatably connected to the adjacent side of the two clamping plates. The driving mechanism is installed between the base and the clamping plates, and two neat unloading mechanisms are symmetrically installed on one side of the upper surface of the base.

[0004] In the above document, the clamping plate is only limited by the two side edges, and the middle area of the paper lacks direct constraint, resulting in high edge tension and insufficient middle area tension, which causes air to accumulate between the middle layers during winding, forming longitudinal wrinkles and affecting the winding quality.
