[0023] In the description of the present application, the terms "first", "second", and the like are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0024] Referring to the accompanying Figures 1-4 , a three-dimensional paper box forming device in an embodiment of the present embodiment includes a folding station, a forming station and a clamping assembly 1, the folding station is provided with a paper standing assembly 12, the paper standing assembly 12 cooperates with the clamping assembly 1, the paper standing assembly 12 includes a first paper standing piece 9 and a second paper standing piece 10, the first paper standing piece 9 and the second paper standing piece 10 are arranged in a staggered manner, the forming station is provided with a forming concave die 2, the forming concave die 2 has a forming cavity, the first paper standing piece 9 and the second paper standing piece 10 are adjustably arranged on the front and rear sides of the forming concave die 2, the first paper standing piece 9 and the second paper standing piece 10 are both L-shaped, the forming station is located below the folding station, the clamping assembly 1 is adjustably arranged, the clamping assembly 1 includes a forming convex die 3 and a bottom support 4, the forming convex die 3 and the bottom support 4 are relatively close or far away, the forming convex die 3 has a clamping area, the clamping area includes a left clamping surface and a right clamping surface, the left clamping surface and the right clamping surface form an included angle, the bottom support 4 is provided with a supporting area corresponding to the clamping area, the supporting area includes a left supporting surface and a right supporting surface, the forming convex die 3 is provided with a pressing edge portion 5 in the circumferential direction, and the pressing edge portion 5 cooperates with the upper surface of the forming concave die 2.

[0025] In the embodiment, the paper feeding member can be a suction nozzle, which is a mature technology. The bottom support 4 is connected with an elastic member or a power source below, so that the bottom support 4 can descend together with the forming punch 3 after clamping the paper blank. In the folding station, the forming punch 3 descends to be close to the bottom support 4, so that the paper blank between the forming punch 3 and the bottom support 4 is folded by force, and finally matches the clamping area and the supporting area. In the folding process, the side plates 8 of the bottom plate 6 on both sides of the center line 7 are bent and stand up due to the corresponding paper standing members. The corresponding paper standing members are arranged in a staggered manner, and the side plates 8 of the paper blank are bent in place after the folding is completed. The clamping assembly 1 drives the paper blank to enter the forming cavity of the forming die 2, and the side plates 8 of the paper blank are bent in place. Finally, the edge pressing part 5 cooperates with the upper surface of the forming die 2 to complete the final edge pressing work, and a three-dimensional paper box is formed. In the embodiment, the paper blank has a pre-fold line, so that the paper blank is accurately bent along the fold line. The smaller the distance between the corresponding paper standing members is, the greater the bending degree of the side plates 8 is.

[0026] Referring to the drawings Figures 1-4 The top of the first paper standing member 9 and the top of the second paper standing member 10 each have a paper supporting surface 11. The distance between the first paper standing members 9 is smaller than the distance between the second paper standing members 10.

[0027] In the embodiment, the first paper standing members 9 and the second paper standing members 10 support the paper blank at the top before folding. The distance between the first paper standing members 9 is smaller than the distance between the second paper standing members 10, so that the bending degree of the corresponding side plates 8 is greater, and the purpose of staggering is achieved.

[0028] In other alternative embodiments, the paper supporting surface 11 can be designed on the left and right sides of the bottom support 4. The first paper standing members 9 and the second paper standing members 10 can be designed side by side in the left-right direction, but the first paper standing members 9 are higher than the second paper standing members 10. The lifting adjustment is suitable for paper blanks of different specifications, which is also a staggered arrangement.

[0029] The above is a preferred embodiment of the present application. It should be pointed out that the protection scope of the present application is not limited to this. For those skilled in the art, without departing from the technical range disclosed in the present application, some improvements, decorations or equivalent replacements can be made under the premise of the same inventive concept, which is also regarded as the protection scope of the present application.
