[0070] In some embodiments, please refer to Figure 8 The step of making the box sheet 10 in step S101 further includes:

[0071] Step S1011: Provide a plastic sheet;

[0072] Plastic sheets are square-shaped sheets.

[0073] Step S1012: The plastic sheet is vacuum-formed to form the cavity 201;

[0074] During the vacuum forming of the cavity 201, the wall of the cavity 13 is stretched, and the thickness of the cavity 13 is less than the thickness of the plastic sheet.

[0080] In short, the box body is manufactured using a single vacuum forming process followed by two or more bending processes, with the bending points achieved through heat bending. Specifically, the box body is first vacuum-formed, and then the first wing plate assembly and the second wing plate assembly are bent simultaneously. Furthermore, the first side plate 102, the second side plate 103, the upper end plate 104, and the lower end plate 105 are bent simultaneously. When the first side plate 102 and the second side plate 103 are bent, the first wing plate assembly connected to the upper end plate 104 and the second wing plate assembly connected to the lower end plate 105 are simultaneously displaced.

[0081] In some embodiments, a heated bending machine can be used to bend the box sheet 10 to reduce labor costs. Preferably, a bending machine that uses infrared or ultrasonic or high-frequency heating can be used to soften the material at the bending point and shape it into a preset shape through electric heating or ultrasonic heating.

[0082] In some preferred embodiments, the bending machine employs a mechanical folding plate, which is positioned at the pre-folding point of the already vacuum-formed part.

[0083] In some preferred embodiments, after the pre-folded area is heated, the box body is bent by mechanical folding driven by a motor, hydraulic or pneumatic.

[0084] In some preferred embodiments, the first wing plate assembly and the second wing plate assembly can be connected to the first side plate 102 and the second side plate 103 respectively by infrared heating, electric heating, high-frequency heating, or ultrasonic heating, or glue can be used to connect them.

[0085] In some preferred embodiments, the box sheet 10 is a flocked sheet or a composite sheet with a cloth surface.

[0086] In this embodiment of the invention, the method includes providing a box sheet 10, the box sheet 10 including a front panel 101, a first side panel 102, a second side panel 103, an upper end panel 104, a lower end panel 105, a first wing panel assembly, and a second wing panel assembly; then bending both the first side panel 102 and the second side panel 103 relative to the front panel until the first side panel and the second side panel are facing each other; bending the upper end panel relative to the front panel 101; bending the first wing panel assembly 106 relative to the upper end panel 104; bending the lower end panel 105 relative to the front panel 101 until the lower end panel 105 and the upper end panel 104 are facing each other; bending the second wing panel assembly 107 relative to the lower end panel 105 to obtain a box body 20; finally providing a casing 30, and fitting the casing 30 onto the box body 20 to obtain the packaging box 100. Using the above method, end plates, first wing plate assemblies and second wing plate assemblies are symmetrically arranged on the panel 101 of the box sheet 10, and the box body 20 is formed by bending. This method is low-cost, easy to produce, and reduces the manufacturing cost of the box body 20.

[0087] Please see Figure 9 , Figure 9 This is a flowchart of another embodiment of the packaging box preparation method of the present invention. The difference between this embodiment and other embodiments is that:

[0093] Setting the third and fourth creases makes folding the box sheet 10 easier and more precise.

[0094] It should be noted that the number of fourth creases is related to the number of wing plates included in the first wing plate assembly 106. For example, if the first wing plate assembly 106 includes a first upper wing plate 1061 and a second upper wing plate 1062, then the number of fourth creases is 2; or, if the first wing plate assembly 106 includes a first upper wing plate 1061, a second upper wing plate 1062, and a third upper wing plate 1063, then the number of fourth creases is 3.

[0095] Prior to step S105, the method further includes:

[0096] S120: A fifth crease is provided at the connection between the lower end plate 105 and the front panel 101; and / or, a sixth crease is provided at the connection between the second wing assembly 107 and the lower end plate 105.
