[0068] Furthermore, the ends of the first fold 19 and the second fold 17, and the ends of the second fold 17 and the third fold 18 are all beveled, and the bevel of the first fold 19 and the bevel of the second fold 17 are connected to form an angle of 90 degrees, and the bevel of the second fold 17 and the bevel of the third fold 18 are connected to form an angle of 90 degrees, so that the packaging box is more regular. The bevel is set according to the use requirements, for example, the bevel of the first fold 19 and the bevel of the second fold 17 are both 45 degrees; for another example, one of the bevel of the first fold 19 and the bevel of the second fold 17 is 30 degrees, and the other is 60 degrees.

[0069] Optional, see Figure 8 As shown, in the first accommodating cavity, a plurality of packages 91 are arranged vertically and in sequence along the arrangement direction; the packaging box also includes an anti-inverting sticker 80 , which is arranged along the arrangement direction and is bonded to the upper ends of all packages 91 .

[0070] Further references Figure 8 As shown, the package 91 is arranged parallel to the YZ direction, and multiple packages 91 are arranged in sequence along the X direction. The anti-inverting sticker 80 is arranged along the X direction, and the anti-inverting sticker 80 spans multiple packages 91. One end of the anti-inverting sticker 80 is located on the outermost package 91 in the negative direction of X, and the other end of the anti-inverting sticker 80 is located on the outermost package 91 in the positive direction of X. In order to better bond the package 91, one end of the anti-inverting sticker 80 is attached to the outer surface of the outermost package 91 in the negative direction of X, and the other end of the anti-inverting sticker 80 is attached to the outer surface of the outermost package 91 in the positive direction of X. The anti-inverting sticker 80 is used to prevent the package 91 from tipping over, enhance the effect of tightening the package 91, and prevent the package 91 from tipping over when the package 91 is unpacked and taken out.

[0071] Furthermore, to prevent the stickiness of the anti-inverting sticker 80 from damaging the packaging 91, the anti-inverting sticker 80 can be adhered to the corner protector 93 of the packaging 91, or a layer of padding paperboard can be added to the outside of the corner protector 93 so that the anti-inverting sticker 80 is adhered to the padding paperboard.

[0072] It is understandable that the number of anti-reverse sticking 80 can be set according to the use requirements. For example, Figure 8 As shown, two anti-inverting stickers 80 are provided; for another example, three anti-inverting stickers 80 are provided.

[0073] Optionally, the anti-inverting sticker 80 is provided with a plurality of parallel folds, the width of adjacent folds is the same as the thickness of the package 91, and when the anti-inverting sticker 80 is attached to the package 91, the folds are just opposite to the gap between the packages 91, and the stickiness of the folds on the anti-inverting sticker 80 is less than or equal to the stickiness of other parts of the anti-inverting sticker 80. When unpacking, a section of the anti-inverting sticker 80 can be folded or torn off according to the folds, and a section of the anti-inverting sticker 80 between the two folds is folded or torn off each time a package is taken, so as to keep other unopened packages 91 still clamped by the anti-inverting sticker 80.

[0074] The packaging box of the embodiment of the present application takes the packaging 91 as a photovoltaic module as an example, wherein the tray 40 is a rectangular structure, and the second channel 42 opening, the first channel 41 opening, and the second channel 42 opening are sequentially arranged on the longer side of the tray 40, and the second channel 42, the first channel 41, and the second channel 42 are all parallel to the width direction of the tray 40; two first channels 41 openings are sequentially arranged on the shorter side of the tray 40, and the two first channels 41 are parallel to the length direction of the tray 40. The steps of assembling, packing, and unpacking the packaging box are as follows:

[0075] Reference Figure 6 As shown, the tray 40 is placed in the second accommodating cavity 75 surrounded by three side baffles 70 , and the bottom of the tray 40 presses the bottom baffle 74 .

[0076] Reference Figure 4 As shown, three side panels 10 are placed in the second accommodating cavity 75, and the first folded edge 19, the second folded edge 17 and the third folded edge 18 are fixedly connected to the tray 40 respectively to form three sides of the surrounding frame 14. In this process, the side panels 10 can be abutted against the side baffle 70 to prevent the side panels 10 from tipping outward, which is convenient for operators to operate.

[0077] After the side panels 10 are connected to the pallet 40, the side baffles 70 can be separated from the pallet 40 and the side panels 10. Alternatively, after the photovoltaic modules are placed on the pallet 40 and before the first strapping band 50 is tied, the side baffles 70 can be separated from the pallet 40 and the side panels 10.

[0078] Install protective corner guards 93 at the four corners of the photovoltaic module, refer to Fig. 9 As shown, the photovoltaic modules are arranged in sequence in the width direction of the tray 40 until the tray is full of photovoltaic modules.

[0079] Reference Figure 8As shown, two first vertical strapping bands 52 pass through the two second channels 42 respectively, and the first vertical strapping bands 52 strap the pallet 40, the photovoltaic module and the second side panel 12. Then, first transverse strapping bands 51 are respectively arranged near the upper and lower sides of the photovoltaic module, and the first transverse strapping bands 51 strap the first side panel 11, the second side panel 12, the third side panel 13 and the photovoltaic module.

[0080] Reference Figure 8 As shown, the anti-flipping 80 is fixed on a straight line formed by the corner guards 93 on both sides of the photovoltaic module in the Y direction.

[0081] Then, the side cover plate 20 is bonded to the first side panel 11 and the third side panel 13 , and the upper cover 30 is covered on the upper end of the surrounding frame 14 .

[0082] Then, the second bundling is performed. Figure 1 As shown, two second vertical strapping straps 62 pass through the two second channels 42 respectively, and one second vertical strapping strap 62 passes through the first channel 41 parallel to the second channel 42, and the second vertical strapping straps 62 bundle the pallet 40, the second side panel 12, the upper cover 30 and the side cover 20. Take two more second vertical strapping straps 62, pass through the two second channels 42 parallel to the length direction of the pallet 40 respectively, and the two second vertical strapping straps 62 bundle the pallet 40, the first side panel 11, the upper cover 30 and the third side panel 13. Then, second transverse strapping straps 61 are respectively arranged on the lateral sides of the photovoltaic module near the upper and lower sides, and the second transverse strapping straps 61 bundle the first side panel 11, the second side panel 12, the third side panel 13 and the side cover 20. The packaging is completed.
