Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Please refer to...

[0066] The flipping mechanism 4 is used to adjust the orientation of item 001.

[0067] In this invention, when an item enters the multi-sided wrapping machine, it first enters the rotary conveyor mechanism 2. Besides its basic conveying function, the rotary conveyor mechanism 2 is equipped with a lifting unit 21 and a film-cutting unit 22. When the item needs to be wrapped, the lifting unit 21 lifts the item and, in conjunction with the pressing mechanism 3, presses it firmly. Then, the rotary conveyor mechanism 2, in conjunction with the lifting film frame mechanism 5, wraps the item. Specifically, the film-cutting unit 22 delivers the film head to a height suitable for the item, the rotary conveyor mechanism 2 rotates the item, and the packaging film of the lifting film frame mechanism 5 wraps the item. When the wrapping is complete, the film-cutting unit 22 can also cut the film, at which point the packaging of the item's sides is finished. Next, the pressing mechanism 3 releases, the flipping mechanism 4 clamps the item and flips it, and then the wrapping process is repeated to complete the all-around wrapping of the item.

[0076] It should be noted that the rotatable pressing member 34 of this utility model is rotatable, and the distance between it and the movable support 32 is elastically variable. That is, under the action of external force, the rotatable pressing member 34 will move closer to the movable support 32, and when the external force disappears or weakens, the rotatable pressing member 34 will move away from the movable support 32 under the action of the elastic element. In this way, the rotatable pressing member 34 can rotate with the rotation of the item, and can elastically press the item tightly without damaging it. During operation, the pressing power 311, specifically a cylinder, controls the movable support 32 to press down along the pressing guide rail 33 through the transmission chain 312, and drives the rotatable pressing member 34 to press down, cooperating with the lifting unit 21 to press the item tightly.
