In addition, the technical features described above in the different embodiments of the present invention may be combined with each other as long as they do not collide with each other.

According to the scheme, as shown in fig. 1 to 7, the winding packaging device is used for externally winding and coating the packaging film on the surface of a product, and the packaging film can effectively protect the product and prolong the shelf life of the product. The main structure comprises: the packaging device comprises a packaging device body 1, a first assembly line 2 and a second assembly line 3, wherein the packaging device body 1 is provided with a through hole 11 which is communicated with the packaging device body, the inner side wall of the through hole 11 is rotatably connected with a packaging roller 12, a film roll 13 is detachably connected to the packaging roller 12, the packaging roller 12 is used for winding and packaging through the rotating film roll 13, the first assembly line 2 is arranged at one end of the through hole 11, and the second assembly line 3 is arranged at the other end of the through hole 11;

wherein the transport surface of the first pipeline 2 and the transport surface of the second pipeline 3 are flush, and the first pipeline 2 and the second pipeline 3 are transported in a first direction (the first direction is the direction indicated in fig. 1, i.e. the direction in which the pipeline extends); at least one end of the through hole 11 is provided with an upper and lower film device 14, and the upper and lower film device 14 has a holding state for holding the packaging film and a unfolding state for releasing the packaging film.

It should be noted that, in the wrapping band wrapping devices in the market today, especially in the drum-type wrapping band wrapping device, when the product starts to be wrapped, a wrapping film is usually wrapped on the product with the assistance of a man to fix the wrapping film before the wrapping film starts to be wound in a rotating manner; when winding packaging is completed, manual film cutting is also needed to separate the product from the packaging film on the equipment. The wrapping tape packaging device has lower packaging efficiency and can not meet the requirements of the current efficient assembly line. And the auxiliary equipment is specially provided with one or two workers, so that the cost is high.

The end of the packaging film on the film roll 13 is clamped by the upper film clamp 141 and the lower film clamp 142 to enable the packaging film to be unfolded.
