[0011] Furthermore, the length of the transverse pressure rod is less than or equal to the vertical distance between the folding plates.

[0012] The utility model has the following beneficial effects: firstly, the cardboard to be folded is placed on the supporting base frame, and then the screw assembly drives the folding plates to rotate in a direction of approaching each other, so that the packaging box cardboard can be automatically folded, reducing the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the overall structure of the packaging box folding device. DETAILED DESCRIPTION

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0015] like Figure 1 In the embodiment of a packaging box folding device shown in the present invention, it includes a supporting base frame 1 and a vertical support plate 2. Folding plates 3 are symmetrically hinged on both sides of the supporting base frame 1. A hydraulic cylinder 4 is fixed on the top of the vertical support plate 2. The output end of the hydraulic cylinder 4 passes through the vertical support plate 2 and is fixed with a transverse pressure rod 41. Screw assemblies 5 for driving the folding plates 3 to rotate are installed on both sides of the supporting base frame 1. Specifically, the cardboard to be folded is first placed on the supporting base frame 1, and then the folding plates 3 are driven to rotate in a direction close to each other by the screw assembly 5, so that the cardboard of the packaging box can be automatically folded, reducing the labor intensity of the staff.

[0016] In one embodiment of the present application, the vertical support plate 2 is fixed to one side of the support base 1 , and the shape of the vertical support plate is “L”-shaped.

[0017] In one embodiment of the present application, the axis of the transverse compression rod 41 is parallel to the central axis of the supporting frame 1 in the longitudinal direction.

[0018] In one embodiment of the present application, the screw assembly 5 includes a limit plate 51 symmetrically arranged on both sides of the support base 1, a slider 52 slidably connected to the limit plate 51, a transmission link 53 and a bidirectional screw 54 threadedly connected to the slider 52. The bidirectional screw 54 passes through the support base 1 and the middle part is a smooth rod. One end of the transmission link 53 is hinged to the side wall of the folding plate 3, and the other end of the transmission link 53 is hinged to the top of the slider 52. Specifically, a limit groove is provided on the top of the limit plate 51 to cooperate with the slider 52. By driving the bidirectional screw 54 to rotate, the sliders 52 are moved closer to or away from each other. When the sliders 52 approach each other, the folding plate 3 is rotated in the direction of the transverse pressure rod 41 through the transmission link 53, so as to automatically fold the packaging box cardboard, saving time and effort.

[0019] In one embodiment of the present application, a motor 6 for driving the bidirectional screw 54 to rotate is fixedly provided on one of the limiting plates 51 .

[0020] In one embodiment of the present application, the motor 6 is a stepper motor.

[0021] In one embodiment of the present application, the length of the transverse compression rod 41 is less than or equal to the vertical distance between the folding plates 3 .

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
