[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] First embodiment:

[0026] like Figures 1 to 3 , Figure 5As shown, the utility model proposes a packaging box bending device, which includes two parallel side baffles 1, the bottom end of the side baffles 1 is fixedly connected with a foot 18, the front and rear ends of the side baffles 1 on both sides are connected to each other by providing a support bar 2, the support bar 2 is provided with a bending mold 3, the rear of the bending mold 3 is provided with a fixing portion 4, the fixing portion 4 and the side baffles 1 are connected to each other by providing a buckle structure 5, so the buckle structure 5 can be operated to achieve the rapid replacement of the bending mold 3, and in one embodiment of the utility model, the bending mold 3 is a flat mold 27, the front end of the flat mold 27 is provided with a straight edge 28, and the rear end of the flat mold 27 is fixedly connected to the fixing portion 4. Moreover, an upper cover plate 13 is fixedly connected between the top front parts of the side baffles 1 on both sides, and a paper slot 14 is formed between the upper cover plate 13 and the bending mold 3, and when bending, the plane of the packaging box enters and exits from the paper slot to be bent.

[0027] Next, a sliding frame 6 is fixedly connected to the front end of the separated sides of the side baffles 1 on both sides, and a bending groove 7 is opened at the front end of the sliding frame 6. The bending groove 7 includes a top 15, a middle part 16 and a bottom 17 that are interconnected. The top 15 and the bottom 17 are parallel to the base 18, the top 15 is shorter than the bottom 17, and the middle part 16 and the base 18 are perpendicular. At the same time, a bending roller 8 is arranged in the bending groove 7, and guide plates 9 are arranged at both ends of the bending roller 8. A handle 12 is fixedly connected between the top ends of the guide plates 9 on both sides, and a sliding frame 10 is opened at the front end of the guide plate 9. The bending roller 8 is slidably connected in the sliding frame 10, and the rear end of the guide plate 9 is rotatably connected with a rotating shaft 11, and the rotating shaft 11 is rotatably connected to the side baffle 1. Therefore, before bending, the bending roller 8 is inside the top 15. At this time, the handle 12 is parallel to the top 15. After the bending begins, the user operates the handle 12 to move, driving the bending roller 8 to move inside the bending groove 7, passing through the top 15 and the middle of the middle part 16 in turn, and finally reaching the bottom 17. In this process, due to the distance between the bending roller 8 itself and the rotating shaft 11, the bending roller 8 will slide and adjust inside the sliding frame 10, and the originally flat paper box original will also be deformed following the pressure of the bending roller 8, thereby achieving the bending effect.

[0028] To further explain the specific working principle of the present invention, the buckle structure 5 includes a cavity 19 opened inside the rear end of the fixing part 4, a slide bar 20 is fixedly connected in the cavity 19, both ends of the slide bar 20 are slidably connected to the slider 21, the front and rear ends of the slider 21 are respectively fixedly connected to the latch 22 and the pressure rod 23, the latch 22 and the pressure rod 23 pass through the cavity 19 and extend to the outside. The side baffle 1 is provided with a groove 24 for matching with the latch 22, the adjacent sides of the grooves 24 on both sides are fixedly connected to the spring 25, the side of the spring 25 away from the latch 22 is fixedly connected to the fixing block 26, and the fixing block 26 is fixedly connected to the inner wall of the cavity 19.

[0029] Therefore, when the bending mold 3 needs to be disassembled, the user only needs to pinch the pressure rod 23 from both ends of the fixing part 4. The pressure rod 23 moves under the force, driving the slider 21 to slide on the slide bar 20, driving the pin 22 to disengage from the groove 24, until it is completely disengaged from the groove 24, the fixing part 4 and the side baffle 1 are released from the limit, and the user can now remove the fixing part 4 and the bending template 3.

[0030] Second embodiment:

[0031] like Figure 4 The utility model shown in the figure proposes a packaging box bending device. In another preferred embodiment of the utility model, the bending mold 3 is a curved mold 29, the front end of the curved mold 29 is provided with a curved edge 30, and the rear end of the curved mold 29 is fixedly connected to the fixed part 4, and different bending shapes can be achieved by bending the curved surface.

[0032] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
