[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] A foldable roll packing box, see Figures 1-4 The protective assembly 3 comprises a base 1, a fixing assembly 2 mounted on the base 1 for securing the material coil 4, and a protective assembly 3. The protective assembly 3 comprises a top cover 31, an inner panel 32, and an outer panel 33, each formed by a plurality of side panels 34. The inner panel 32 is detachably connected to the base 1 and fits over the outer side of the fixing assembly 2. Its height is no less than the maximum height of the material coil 4 when mounted on the support assembly, ensuring that the material coil 4 can fit within the inner panel 32. The multiple side panels 34 of the inner panel 32 are foldable. The outer panel 33 is connected to the base 1 and fits over the outer side of the inner panel 32. Its height is higher than the fixing assembly 2 but lower than the maximum height. The top cover 31 is used to cover the inner panel 32 when packaging the material coil 4 and to cover the outer panel 33 during the recycling process. The coiled material 4 packaging box described above has an inner panel 32 that is detachably connected and foldable. When recycling the packaging box, it can be removed from the base 1, folded, and then placed inside the outer panel 33. Since the outer panel 33 is lower than the maximum height, that is, lower than the inner panel 32, the height and volume of the entire packaging box are reduced during recycling, thereby reducing the space occupied by the packaging box, which is conducive to improving recycling efficiency and reducing recycling costs. The folded inner panel 32 is placed inside the outer panel 33, which can protect the inner panel 32 from damage and prevent it from being lost. The outer panel 33 is higher than the fixed component 2. In this way, when recycling the packaging box, the outer panel 33 can surround the fixed component 2, thereby protecting the fixed component 2 from damage.

[0028] In this embodiment, the base 1 is provided with an inner ring retaining groove and an outer ring retaining groove, and the inner and outer panels 32 and 33 are respectively retained in the inner and outer ring retaining grooves. The above connection structure between the inner and outer panels 32 and 33 is simple, which is convenient for both assembly and processing. The same connection structure can also be used between the top cover 31 and the two panels.

[0029] In this embodiment, the inner panel 32 includes a folding plate formed by at least two side panels 34. There are two groups of folding plates, and the two groups of folding plates are connected at the head. Preferably, the folding plate is formed by three side panels 34, and its cross-sectional shape is U-shaped. The two groups of folding plates are connected end to end to form a U-shaped inner panel 32. Alternatively, the folding plate can also be formed by two side panels 34, and its cross-sectional shape is L-shaped. The two groups of folding plates are connected end to end to form a U-shaped inner panel 32. The inner panel 32 is set as two groups of U-shaped or L-shaped folding plates. When connected, the U-shaped or L-shaped folding plates are more stable and reliable than a single plate connection, which improves the connection stability and reliability and reduces the occurrence of shaking. When folding, the folding steps of the U-shaped or L-shaped folding plates are simple.

[0030] In some other embodiments, the inner panel 32 includes a group of folding panels and a side panel 34. The folding panel is formed by at least three side panels 34, preferably by three side panels 34, and its cross-sectional shape is U-shaped. The folding panel and the side panel 34 are connected at the first position.

[0031] In this embodiment, the plurality of side panels 34 of the peripheral panel 33 are integrally formed. The integrally formed peripheral panel 33 has higher connection stability and reliability, and can improve the assembly effect.

[0032] In this embodiment, the fixing assembly 2 includes a first fixing seat 21 and a second fixing seat 22 arranged along the length of the base 1. The first fixing seat 21 and the second fixing seat 22 are both provided with a support plate 23 for supporting the coil 4. Preferably, the support plate 23 is semicircular, which adapts to the shape of the core 41 of the coil 4 and can better support the limited core. A limiter 24 is provided on the support plate 23. The limiter 24 cooperates with the support plate 23 to fix the coil 4 to the support plate 23. This can improve the installation reliability of the coil 4, prevent the coil 4 from moving during transportation and causing damage due to collision between the coils 4, and improve the protective effect. Preferably, the limiter 24 is semicircular.

[0033] The first fixing seat 21 and the second fixing seat 22 each include a connecting seat 211 and a fixing frame 212. The connecting seat 211 is connected to the base 1, and the fixing frame 212 is provided with the support plate 23 and the limiting member 24. The connecting seat 211 is provided with a groove 2111 facing the other fixing seat. The side wall of the groove 2111 is provided with a slide groove 2112 arranged in the vertical direction and a limiting groove 2113 arranged above the slide groove 2112. The limiting groove 2113 penetrates the top surface of the connecting seat 211. The fixing frame 212 is provided with a slider 2121 slidingly arranged in the slide groove 2112 and a limiting block 2122 that cooperates with the limiting groove 2113 to limit the position. When the coil 4 is installed, the limiting block 2122 of the fixing frame 212 is clamped in the limiting groove 2113, thereby fixing the fixing frame 212 is fixed to the connecting seat 211. When the packaging box is recycled, the limit block 2122 of the fixing frame 212 removes the limit slot 2113 upward. At this time, the fixing frame 212 can rotate along the slider 2121 (the slider 2121 can also move along the slide slot 2112), so that the fixing frame 212 and the support plate 23 and the limit member 24 arranged on the fixing frame 212 can be rotated to the horizontal plane, which reduces the height of the recycled packaging box, further reduces the volume, reduces the space occupied by the packaging box, and is conducive to improving recycling efficiency and reducing recycling costs.

[0034] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
