[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] A foldable cylindrical film roll packaging structure, see Figures 1-4 , comprising a base 100, at least one layer of surrounding plates 200 arranged on the base 100, and a top cover 300 covering the surrounding plates 200. Among them, the surrounding plates 200 of the present embodiment are three, of course, it can also be other quantities, which can be set according to the need, in order to facilitate the description, the first surrounding plate 200 is described below. The top cover covers the uppermost surrounding plate 200.

[0033] In the present embodiment, the base 100 comprises a bearing plate 110 and a plurality of support blocks 120 arranged at the bottom of the bearing plate 110, and the adjacent two support blocks 120 are arranged at intervals. The support blocks 120 are arranged at intervals above, when carrying, the forklift can be inserted into the gap between the support blocks 120, and then the whole packaging structure is carried, which is convenient for carrying.

[0034] ​In the embodiment, the enclosure 200 comprises four side plates 210, and two adjacent side plates 210 are rotatably connected so that two of the side plates 210 can be rotated to be flat against the other two side plates 210 and can be rotated to be perpendicular to each other. The two opposite side plates 210 are respectively a first side plate 211 and a second side plate 213, and the first side plate 211 and the second side plate 213 are respectively provided with at least one first through hole 212 and at least one second through hole 214. In the embodiment, there are three through holes, and the first through hole 212 and the second through hole 214 are arranged one by one. The bottom of each side plate 210 is provided with a first limiting rib 215, one end of the first limiting rib 215 is connected to the bottom of the corresponding side plate 210, and the other end of the first limiting rib 215 extends out of the corresponding side plate 210 and is limited in cooperation with the side wall of the base 100 (if the enclosure 200 is the second layer and above, the first limiting rib 215 is limited in cooperation with the side plate 210 of the lower enclosure 200).

[0035] During transportation, the four side plates 210 are rotated to be perpendicular to each other, and the two ends of the cylindrical film roll 400 are arranged in the first through hole 212 and the second through hole 214 respectively, so as to fix the cylindrical film roll on the enclosure 200. The bottom of each side plate 210 of the enclosure 200 is provided with a first limiting rib 215, and when the enclosure 200 is stacked, the four side plates 210 are clamped on the base 100 through the corresponding first limiting rib 215 (if the enclosure 200 is the second layer and above, the four side plates 210 are clamped on the lower enclosure 200 when stacked), which is convenient to use. Since the two adjacent side plates 210 are rotatably connected, when the cylindrical film roll does not need to be packaged, the four side plates 210 can rotate two of the side plates 210 to be flat against the other two side plates 210, at this time, the four side plates 210 are folded into two layers, and the occupied volume is smaller. The folded enclosure 200 is convenient to store and is not easy to be damaged, which can improve the service life and recycling rate.

[0036] The first and second through holes 214 are formed by two semicircular holes. Specifically, the surrounding plate 200 comprises a lower surrounding plate 220 and an upper surrounding plate 230 stacked on the lower surrounding plate 220. The lower surrounding plate 220 comprises four lower side plates 221, and adjacent two lower side plates 221 are rotatably connected. Opposite two lower side plates 221 are a first lower side plate 222 and a second lower side plate 224 respectively. The first lower side plate 222 and the second lower side plate 224 are respectively provided with at least one first semicircular hole 223 and at least one second semicircular hole 225, and the first semicircular hole 223 and the second semicircular hole 225 are arranged one by one in correspondence. The upper surrounding plate 230 comprises four upper side plates 231, and adjacent two upper side plates 231 are rotatably connected. Opposite two upper side plates 231 are a first upper side plate 232 and a second upper side plate 234 respectively. The first upper side plate 232 and the second upper side plate 234 are respectively provided with at least one third semicircular hole 233 and at least one fourth semicircular hole 235, and the third semicircular hole 233 and the fourth semicircular hole 235 are arranged one by one in correspondence. After the upper surrounding plate 230 and the lower surrounding plate 220 are stacked, one first semicircular hole 223 and one third semicircular hole 233 are arranged opposite to form a first through hole 212, and one second semicircular hole 225 and one fourth semicircular hole 235 are arranged opposite to form a second through hole 214. The bottom of the lower surrounding plate 220 is provided with the first limiting rib 215 described above. When packaging the cylindrical film roll, the lower surrounding plate 220 is clamped on the base 100 through the first limiting rib 215 (if it is the second and above surrounding plate 200, it is clamped on the upper surrounding plate 230 below during stacking), then the cylindrical film roll is placed on the lower surrounding plate 220, and then the upper surrounding plate 230 is arranged on the lower surrounding plate 220, so as to clamp the cylindrical film roll, and finally fix the cylindrical film roll. The surrounding plate 200 is arranged to be provided with the upper surrounding plate 230 and the lower surrounding plate 220 with semicircular holes, which facilitates the loading of the cylindrical film roll onto the surrounding plate 200.

[0037] Each bottom of the upper surrounding plate 230 is provided with a second limiting rib 236, one end of the second limiting rib 236 is connected to the bottom of the corresponding upper side plate 231, and the other end of the second limiting rib 236 extends out of the corresponding upper side plate 231 and is limited and matched with the lower side plate 221. In this way, the upper surrounding plate 230 can be stacked on the lower surrounding plate 220 through the second limiting rib 236.

[0038] In the embodiment, the first limiting rib 215 and the second limiting rib 236 have the same structure. Taking the first limiting rib 215 as an example, the longitudinal section of the first limiting rib 215 is in a stepped shape. When the first limiting rib 215 is installed on the corresponding side plate 210, the bottom surface of the first limiting rib 215 is connected to the side plate 210, and the tread surface of the first limiting rib 215 extends to the position outside the lower side of the side plate 210. During stacking, the surrounding plate 200 is clamped on the base 100 through the tread. Since the tread is located outside the surrounding plate 200, there is a certain assembly allowance, which facilitates the clamping of the surrounding plate 200.

[0039] In the embodiment, the first limiting ribs 215 on the enclosure 200 are symmetrically arranged at the center, so that the stacked enclosure 200 has higher stability.

[0040] In the embodiment, the distance between the center position of the first through hole 212 and the top and bottom of the corresponding side plate 210 is greater than the radius of the cylindrical film roll, and the distance between the center position of the second through hole 214 and the top and bottom of the corresponding side plate 210 is greater than the radius of the cylindrical film roll, so that the cylindrical film roll can be hung on the enclosure 200.

[0041] In the embodiment, the two side plates 210 adjacent to the first side plate 211 are not provided with the through hole structure, so that the material roll of the cylindrical film roll can be protected, and the problem that the material roll is damaged by the outside through the through hole can be avoided.

[0042] In the embodiment, the enclosure 200 further comprises a plurality of hinges 240, and the adjacent two side plates 210 are connected through the hinges 240.
