[0034] This embodiment provides a bending machine that can be used to bend Figure 6 The plate 6 shown is folded into Figure 7 The box-shaped structure shown. The plate-shaped object 6 includes a first direction ( Figure 1The first bending portion 62, the second bending portion 63, the third bending portion 64, the fourth bending portion 65 and the base portion 61 are sequentially connected in the X direction and the reverse direction thereof, wherein the X direction is the positive direction of the first direction. The first bending portion 62, the second bending portion 63, the third bending portion 64 and the fourth bending portion 65 are each provided with two at intervals along the second direction. The two fourth bending portions 65 are connected to the same base portion 61. The plate-like object 6 also includes a fifth bending portion 66. There are also two fifth bending portions 66, which are respectively connected to the base portion 61 along the second direction ( Figure 1 On opposite sides of the folded portion 66 (in the middle Y direction and the opposite direction), the two fifth bends 66 are further connected to a sixth bend 67 on one side away from the base portion 61. The first bend 62 and the third bend 64 are rectangular in shape, and the second bend 63 and the fourth bend 65 connecting the same third bend 64 are rectangular in shape. Any adjacent bends (including the first bend 62, the second bend 63, the third bend 64, the fourth bend 65, the fifth bend 66, and the sixth bend 67) are capable of bending. After bending, the first bend 62, the second bend 63, the third bend 64, the fourth bend 65, the fifth bend 66, and the sixth bend 67 can form a hollow cube structure with openings at opposite ends along the first direction. After bending, the fifth bend 66 can block the opening at one end of the cube structure along the second direction. After bending, the sixth bend 67 can be inserted into the cube structure from the opening to prevent the fifth bend 66 from being separated from the opening. It is understandable that the bending machine proposed in this embodiment can also be used to fold plate-like objects 6 of other shapes. For example, the plate-like object 6 includes a first bending portion 62, a second bending portion 63, a third bending portion 64, a fourth bending portion 65, and a base portion 61 connected in sequence along a first direction. The first bending portion 62, the second bending portion 63, the third bending portion 64, the fourth bending portion 65, and the base portion 61 are each provided in a single portion. The plate-like object 6 also includes two fifth bending portions 66 respectively provided on opposite sides of the base portion 61 along the second direction. The side of the fifth bending portion 66 away from the base portion 61 is further connected to a sixth bending portion 67. The first direction and the second direction are two directions perpendicular to each other in a horizontal plane.

[0035] refer to Figure 1-Figure 5As shown, the bending machine proposed in this embodiment includes a carrier 1, a first driving member 4, a pressing mechanism 2, a bending mechanism 3 and a forming mechanism 5, wherein the carrier 1 is connected to the first driving member 4, the first driving member 4 is arranged below the carrier 1 and connected to the carrier 1, the first driving member 4 is configured to drive the carrier 1 to move along a first direction, the carrier 1 is used to support a plate-like object 6, the pressing mechanism 2 is arranged above the carrier 1, and is used to cooperate with the carrier 1 to press the plate-like object 6, the bending mechanism 3 is arranged on the opposite side of the carrier 1 along the first direction, and is used to bend the first The bending portion 62, the second bending portion 63, the third bending portion 64 and the fourth bending portion 65; the forming mechanism 5 includes a front pressure component 51, a rear pressure component 52 and a side pressure component 53, the front pressure component 51 is used to push the first bending portion 62 after bending in the opposite direction of the first direction; the rear pressure component 52 is arranged above the carrier 1, and the rear pressure component 52 is used to press down the third bending portion 64 after bending, and the two side pressure components 53 are respectively arranged on the opposite sides of the second direction of the carrier 1, and the side pressure component 53 is used to press down the sixth bending portion 67 after bending.

[0036] When folding a paper box, the fifth bending portion 66 and the sixth bending portion 67 provided on both sides of the plate 6 are manually bent, and then placed on the carrier 1. The plate 6 is fixed by the pressing mechanism 2 in cooperation with the carrier 1, and the bent sixth bending portion 67 is pressed down by the side pressing assembly 53 to prevent the sixth bending portion 67 from bouncing up. The carrier 1 moves in the first direction (when the carrier 1 moves, the pressing mechanism 2 releases the plate 6), so that the corresponding bending portions can be respectively aligned with the bending mechanism 3, and the bending mechanism 3 is sequentially pressed down. The first bending portion 62, the second bending portion 63, the third bending portion 64 and the fourth bending portion 65 aligned therewith are bent. After the fourth bending portion 65 is bent, the front pressing assembly 51 pushes the first bending portion 62 in the opposite direction of the first direction, so that the first bending portion 62 is bent toward the side closer to the first bending portion 62 relative to the third bending portion 64. Then, the rear pressing assembly 52 applies a downward force to the third bending portion 64, so that the first bending portion 62 is fitted with the base portion 61, and the entire paper box is folded. The above-mentioned bending machine improves the production efficiency of paper boxes.

[0037] refer to Figure 1 As shown, the first driving member 4 adopts a linear module. In order to limit the plate-like object 6, the carrier 1 includes a carrier body 11, a first side 12, a second side 13, a third side 14 and a fourth side 15, wherein the first side 12 and the second side 13 are arranged on the carrier body 11 at intervals along the first direction, and the third side 14 and the fourth side 15 are arranged on the carrier body 11 at intervals along the second direction. The first side 12, the second side 13, the third side 14 and the fourth side 15 are surrounded to form a contoured groove for limiting the plate-like object 6, and the plate-like object 6 is placed in the contoured groove.

[0038] Specifically, to reduce the difficulty of placing the plate-like object 6 in the contoured groove, the tops of the first rib 12, the second rib 13, the third rib 14, and the fourth rib 15 are each provided with a guide surface, which gradually rises from the side facing the interior of the contoured groove to the other side. It should be noted that in order for the side pressure assembly 53 to apply pressure to the sixth bend 67, the height of the third rib 14 and the fourth rib 15 is no higher than the width of the fifth bend 66 along the first direction. In addition, there is a gap between the first rib 12 and the third rib 14 and the fourth rib 15 to prevent the first rib 12 from interfering with the bending mechanism 3 in bending the first bend 62 to the fourth bend 65. Similarly, there is a gap between the second rib 13 and the third rib 14 and the fourth rib 15 to prevent the second rib 13 from interfering with the front pressure assembly 51 in pushing the first bend 62.

[0039] More specifically, the third side 14 and the fourth side 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 rise and fall, thereby cooperating 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 pressure component 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 and third driving members 22 and 23 are both pneumatic cylinders. The pressing portion 212 is formed by bending the lower end of the main body 211. 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 which is connected to the main body 211 and the other end is connected to the pressing portion 212. At the same time, to prevent burrs from damaging the plate-like object 6, the end of the pressing portion 212 away from the main body 211 is bent upward.

[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 uses 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 via the connecting portion, and the connecting portion is vertically arranged. Taking the fourth bent 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 the fourth bent portion 65. As the upper support plate 31 continues to rise, the angle between the fourth bent portion 65 and the base portion 61 gradually decreases until the connecting portion contacts the fourth bent portion 65. Since the connecting portion is vertically arranged, the angle between the fourth bent portion 65 and the base portion 61 is maintained at 90°.

[0045] refer to Figure 4 As shown, the side pressure assembly 53 includes a fifth driving member 532 and a side pressure plate 531 . The fifth driving member 532 is configured to drive the side pressure plate 531 to move along the second direction so that the sixth bending portion 67 maintains a bent state.

[0046] Specifically, the fifth driving member 532 also adopts a cylinder and is fixed under the carrier 1. The side pressure plate 531 is set to be L-shaped, with one vertical end connected to the output end of the fifth driving member 532 and the other end extending toward the other side pressure plate 531.

[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 make rational use of 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 seventh driving member 513 is arranged at the output end of the sixth driving member 512. The seventh driving member 513 is configured to drive the front pressure plate 511 to rise and fall. 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 push the two first bending portions 62 on the plate-like object 6 respectively. 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.

[0050] refer to Figure 2 and Figure 3 As shown, the rear pressure assembly 52 includes a rear pressure plate 521, an eighth driving member 522 and a ninth driving member 523. The eighth driving member 522 is configured to drive the rear pressure plate 521 to rise and fall, and the ninth driving member 523 is configured to drive the rear pressure plate 521 to move along the first direction. Under the action of the eighth driving member 522, the rear pressure plate 521 can apply downward pressure to the bent third bending portion 64.

[0051] Specifically, the ninth driving member 523 is arranged at the output end of the eighth driving member 522, and the rear pressure plate 521 is arranged at the output end of the ninth driving member 523. The eighth driving member 522 and the ninth driving member 523 both use cylinders. The cross-section of the rear pressure plate 521 is arranged to be approximately L-shaped, and one end of the horizontally arranged rear pressure plate 521 is bent upward to avoid burrs damaging the plate-like object 6.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
