[0028] Working principle: When in use, the goods are stacked on the rotating load-bearing platform 6 and fixed. At this time, the rotating load-bearing platform 6 is started on the control box 1, and the rotating load-bearing platform 6 begins to rotate with the goods. At the same time, hydraulic oil is introduced into the hydraulic oil pump 49 according to the compiled program, and the lifting and lowering of the hydraulic cylinder 7 is controlled by the separate solenoid valve 8 on each hydraulic cylinder 7. At the same time, the horizontal displacement system 3 and the vertical displacement system 4 interact with each other to make the film-wrapping rod assembly 5 pull out the film from the film-wrapping clamp and rotate around the goods to evenly cover the film on the goods. When the film-wrapping rod 30 moves to the bottom of the goods, the nearest batch of hydraulic cylinders 7 will retract so that the film-wrapping rod 30 will not be hindered by the hydraulic cylinder 7. After the film-wrapping rod 30 moves out of this part of the hydraulic cylinder 7, this part of the hydraulic cylinder 7 rises again to support the goods. Each batch of hydraulic cylinders 7 behind makes the same movement, that is, all the hydraulic cylinders 7 will do wave-like ups and downs so that the film-wrapping rod 30 passes through the bottom of the goods. After the film is wrapped on all sides of the goods, the goods are removed from the rotating load-bearing platform and the film coating is completed.

[0029] Based on the above, the invention can utilize the wave-like lifting of the bottom hydraulic cylinder to achieve the purpose of wrapping the film rod around the bottom of the goods for film coating, and cooperate with the rotating load-bearing platform to achieve all-round film wrapping of the goods.

[0030] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
