[0020] Refer to the accompanying drawings. The central axis mechanism provided by the present invention includes a central axis component 1, and a central axis 11 is arranged at the central part of the central axis component 1. In this embodiment, the wrapping machine is provided with two bearings, namely a bearing 21 connected to the central axis and a plane bearing 22 placed on the periphery of the bearing 21. The number and type of bearings can vary according to different situations. The central axis component is provided with a bearing support structure 12 for these bearings on the periphery of the central axis 11. A plurality of first limiting structures 13 are also arranged on the periphery of the central axis component 1. The central axis component is fixed and limited in the base of the wrapping machine by the first limiting structures 13. The limiting direction can be that the first limiting structure 13 is limited by the limiting structure in front of it according to the rotation direction of the turntable 200 of the wrapping machine when wrapping the film onto the article as the forward direction.

[0021] A central axis mechanism installation hole 101 is provided in the winding machine base 100, and a connecting groove 5 is provided circumferentially around the central axis mechanism installation hole to form a limiting structure with the central axis mechanism installation hole, the notch of the connecting groove 5 faces the central axis mechanism installation hole 101, and the connecting groove has an open portion 51 for the first limiting structure 13 to be placed; the central axis mechanism installation hole 101 and the open portion form a central axis component placement hole, and by rotating the central axis component 1, the first limiting structure 13 can be stuck between the upper groove wall 52 and the lower groove wall 53 of the connecting groove, and the first limiting structure 13 is connected to the upper groove wall 52 and the lower groove wall 53 of the connecting groove as a whole by bolts. Bolt holes are prefabricated for the first limiting structure 13, the upper groove wall 52 and the lower groove wall 53, wherein the bolt hole of the lower groove wall 53 is a threaded connection hole.

[0022] The connection groove can adopt a three-layer structure, which is not only reliably connected to the central axis component and convenient to install, but also very suitable for thin design, which helps to reduce the height of the winding machine turntable.

[0023] The central axis mechanism is provided with an upper limit structure 3 as an upper structure. The upper limit structure 3 is a ring-shaped structure, and a plurality of keys protruding inward are provided on the inner side thereof. The keys form an upper groove wall that limits the first limit structure. The intervals between the keys constitute the open portion 51. The center hole of the ring-shaped structure forms the center insertion hole. The upper limit structure is made of a metal plate; the upper limit structure 3 is made of a metal plate.

[0024] The central axis mechanism is provided with a middle limiting structure 4 as a middle structure. The middle limiting structure 4 is a ring-shaped structure, forming the groove bottom 55 of the connecting groove, and has a plurality of keys protruding inward on the inner side thereof. The keys are used as the limiting structure in front of the first limiting structure (according to the forward direction of the rotation direction of the turntable 200 when the winding machine wraps the film onto the article), and the limiting structure is named as the second limiting structure 54. When the first limiting structure 13 is turned to be blocked by the second limiting structure 54, the first limiting structure 13 is stuck between the upper and lower groove walls 52 and 53 of the connecting groove, and the bolt holes 130 set on the first limiting structure 13 are aligned with the bolt holes 520 and 530 on the upper and lower groove walls 52 and 53. In this way, at the installation site, just put the central axis component 1 into the central axis component insertion port, and then rotate it until the first limiting structure 13 touches the second limiting structure 54, and then directly fix it with bolts. The central axis component 1 is stuck in the connecting groove 5, and the installation is very reliable and not easy to deform. The middle limiting structure is also made of metal plate.

[0025] The lower groove wall as the lower structure can directly adopt the base 100.

[0026] The upper limit structure 3 and the middle limit structure 4 can be fixedly connected to the lower groove wall by bolts or welding.
