In order to limit the plate-like object 6, the carrier 1 includes a carrier body 11, a first flange 12, a second flange 13, a third flange 14 and a fourth flange 15, wherein the first flange 12 and the second flange 13 are arranged on the carrier body 11 at intervals along the first direction, and the third flange 14 and the fourth flange 15 are arranged on the carrier body 11 at intervals along the second direction. The first flange 12, the second flange 13, the third flange 14 and the fourth flange 15 are surrounded by a contoured groove for limiting the plate-like object 6, and the plate-like object 6 is placed in the contoured groove.

[0038] Specifically, in order to reduce the difficulty of placing the plate-like object 6 in the profiling groove, the tops of the first rib 12, the second rib 13, the third rib 14 and the fourth rib 15 are all provided with guide surfaces, and the guide surfaces gradually rise from one side facing the inside of the profiling groove to the other side. It should be noted that in order to enable the side pressure assembly 53 to apply pressure to the sixth bending portion 67, the height of the third rib 14 and the fourth rib 15 is not higher than the width of the fifth bending portion 66 along the first direction, and there is a gap between the first rib 12 and the third rib 14 and the fourth rib 15 to avoid the setting of the first rib 12 affecting the bending mechanism 3 from bending the first bending portion 62 to the fourth bending portion 65, and there is a gap between the second rib 13 and the third rib 14 and the fourth rib 15 to avoid the setting of the second rib 13 affecting the front pressure assembly 51 from pushing the first bending portion 62.

[0039] More specifically, the third side guard 14 and the fourth side guard 15 are both L-shaped, with the first end extending in the first direction and the second end extending in the second direction, and an avoidance gap is provided on the inner side of the corner formed by connecting the first end and the second end to prevent interference with the fifth bending portion 66 after bending, thereby affecting the final paper box forming effect.

[0040] refer to Figure 2 and Figure 3 As shown, the pressing mechanism 2 includes a second driving member 22, a third driving member 23 and a pressing plate 21. The second driving member 22 is configured to drive the pressing plate 21 to move up and down, so as to cooperate with the carrier 1 to fix the plate-like object 6. The third driving member 23 is configured to drive the pressing plate 21 to move along the first direction to avoid the rear pressing assembly 52.

[0041] Specifically, the third driving member 23 is arranged at the output end of the second driving member 22, and the lower pressure plate 21 is arranged at the output end of the third driving member 23. In order to avoid the first retaining edge 12, the lower pressure plate 21 includes a main body 211 and a lower pressure portion 212, wherein the main body 211 is connected to the third driving member 23, and two lower pressure portions 212 are arranged at intervals along the second direction. One end of the lower pressure portion 212 is connected to the main body 211, and the other end extends along the first direction. When the lower pressure plate 21 descends, the lower pressure portion 212 can contact the base portion 61 of the plate-like object 6, thereby cooperating with the carrier 1 to fix the plate-like object 6.

[0042] More specifically, the second driving member 22 and the third driving member 23 are both cylinders, and the pressing portion 212 is formed by bending the lower end of the main body 211. In order to ensure the structural strength of the lower pressing plate 21, the lower pressing plate 21 also includes an L-shaped reinforcing rib 213, one end of the reinforcing rib 213 is connected to the main body 211, and the other end is connected to the pressing portion 212. At the same time, in order to avoid damaging the plate-like object 6 due to burrs, the pressing portion 212 is bent upward at one end away from the main body 211.

[0043] refer to Figure 2and Figure 3 As shown, the bending mechanism 3 includes a fourth driving member 32 and an upper support plate 31. The upper support plate 31 is arranged at the output end of the fourth driving member 32. The fourth driving member 32 is configured to drive the upper support plate 31 to rise and fall. The upper support plate 31 rises multiple times to bend the first bending portion 62, the second bending portion 63, the third bending portion 64 and the fourth bending portion 65 in sequence.

[0044] Specifically, the fourth driving member 32 also adopts a cylinder, and the upper support plate 31 includes a mounting portion, a connecting portion and an upper support portion, wherein the mounting portion is fixedly connected to the output end of the fourth driving member 32, the upper support portion is horizontally arranged and connected to the mounting portion through the connecting portion, and the connecting portion is vertically arranged. Taking the fourth bending portion 65 as an example, when the upper support plate 31 rises under the action of the fourth driving member 32, the upper support portion abuts against the fourth bending portion 65. As the upper support plate 31 continues to rise, the angle between the fourth bending portion 65 and the base portion 61 gradually decreases until the connecting portion contacts the fourth bending portion 65. Since the connecting portion is vertically arranged, the angle between the fourth bending portion 65 and the base portion 61 is maintained at 90°.

[0047] refer to Figure 2 and Figure 3 As shown, the front pressure assembly 51 includes a front pressure plate 511 and a sixth driving member 512. The front pressure plate 511 is located on the positive side of the bending mechanism 3 along the first direction. The sixth driving member 512 is configured to drive the front pressure plate 511 to move along the first direction. Under the action of the sixth driving member 512, the front pressure plate 511 can push the first bending portion 62 in the opposite direction of the first direction.

[0048] In order to rationally utilize the space and reduce the space occupied by the front pressure assembly 51 in the first direction, the sixth driving member 512 is arranged below the carrier 1, and the front pressure assembly 51 also includes a seventh driving member 513.

The front pressure plate 511 includes a first state below the carrier 1 and a second state above the carrier 1. The conversion of the front pressure plate 511 between the first state and the second state is realized by the seventh driving member 513. Before the fourth bending portion 65 is bent, the front pressure plate 511 is in the first state. After the fourth bending portion 65 is bent, the front pressure plate 511 switches to the second state.

[0049] Specifically, the sixth driving member 512 and the seventh driving member 513 also use cylinders, and two front pressure plates 511 are arranged at intervals along the second direction to respectively push the two first bending portions 62 on the plate-like object 6. The two front pressure plates 511 are each connected to a seventh driving member 513, and the two seventh driving members 513 are installed on the same sixth driving member 512 through a mounting plate 514.
