[0029] When in use, first stack the carton boards and place them in the feeding bin 3; then, the first feeding robot 4 can move into the feeding bin 3, grab the bottom carton board, and move the carton board to the supporting plate 2; then, the first feeding robot 4 moves along the channel hole 21, moves the carton board and places it on the first folding box part 22; then, the second feeding robot 6 grabs the upper end surface of the carton board, and pulls the carton board upward to form a square box shape; then, the folding box bottom mechanism 5 folds the bottom of the packaging box; then, the first feeding robot 4 releases the packaging box, and the second feeding robot 6 moves the packaging box and places it on the second folding box part 23; then, the folding box cover mechanism 7 folds the box cover of the packaging box; at this point, the folding work of the packaging box can be completed.

[0030] The focus of the present invention is that the automatic box folding machine of the present invention places the carton board in the feeding bin 3, and then conveys the carton board on the supporting plate 2 through the first feeding robot 4 and the second feeding robot 6. During the conveying process, the carton board is folded into a packaging box through the folding box bottom mechanism 5 and the folding box cover mechanism 7, thereby replacing manual folding. The folding speed of the automatic box folding machine is faster than that of manual folding, which can greatly improve the efficiency of packaging box folding, and requires fewer operators, which can greatly reduce the cost of packaging box folding.

[0031] The feeding bin 3 comprises two fixed side plates 31, which are adjacent to each other and perpendicular to each other and are fixed on the machine frame 1;

[0033] Before use, the position of the two movable side panels 33 can be adjusted by the shifting mechanism 32, and then the distance between the two movable side panels 33 and the two fixed side panels 31 can be adjusted, so as to adjust the size of the feeding bin 3 to adapt to carton boards of different sizes. When in use, the carton board can be placed in the two fixed side panels 31 and the two movable side panels 33, and placed on the bottom support rod 34. At the same time, the two movable side panels 33 slightly clamp the carton board to prevent the stacked carton boards from falling off the bottom support rod 34 due to excessive weight; after the first feeding manipulator 4 enters the feeding bin 3, it grabs the bottom carton board and pulls the carton board off the bottom support rod 34, and the remaining carton boards fall on the bottom support rod 34, waiting for the next grab by the first feeding manipulator 4.

[0034] The bottom support rod 34 is a cylindrical rod, and the surface of the bottom support rod 34 is polished. By setting the bottom support rod 34 as a cylindrical rod and polishing it, the first feeding robot 4 can smoothly pull down the carton board, avoiding the stacked carton boards from pressing the bottom carton board too tightly on the bottom support rod 34, resulting in the failure of the first feeding robot 4 to pull down the carton board.

[0035] The movable side plate 33 arranged perpendicular to the length direction of the paper box board is provided with an opening 331, and the bottom support rod 34 adjacent to the opening 331 is provided with an extension section 341 extending outward from the opening 331. Before the paper box board is folded into a packaging box, the box cover portion is generally provided with a longer top plate for bending into the box cover and the top tongue, and the top plate can extend out of the feeding bin 3 through the opening 331 and be placed on the extension section 341.

[0036] The above-mentioned first feeding robot 4 includes a first horizontal cylinder 41, which is installed on the body frame 1 and is located below the channel hole 21; a first vertical cylinder 42, which is installed on the first horizontal cylinder 41; and a first suction cup assembly 43, which is installed on the first vertical cylinder 42.

[0037] When in use, the first vertical cylinder 42 is moved to the bottom of the feeding bin 3 by the first horizontal cylinder 41; then, the first vertical cylinder 42 sends the first suction cup assembly 43 into the feeding bin 3, and grabs the carton board by the first suction cup assembly 43; then, the first vertical cylinder 42 moves downward to pull the carton board down to the supporting plate 2; then, the first vertical cylinder 42 is driven by the first horizontal cylinder 41 to move toward the first folding box part 22, and the carton board is moved and placed on the first folding box part 22.

[0038] The above-mentioned folding box bottom mechanism 5 includes a box bottom plate bending component 51, and the box bottom plate bending component 51 includes a second vertical cylinder 511 and a first bending plate 512.

The second lateral cylinder 541 drives the two closing rods 543 to withdraw from the packaging box, and then drives the two closing rods 543 to move toward the packaging box, slightly pushing the box bottom plate, the two dust-proof wings and the box bottom tongue into the packaging box, so that the box bottom plate, the two dust-proof wings and the box bottom tongue are plugged into each other; at this point, the folding of the box bottom is completed.

[0040] The above-mentioned folding box bottom mechanism 5 also includes a first positioning assembly 55, which includes a fourth vertical cylinder 551 and a second suction cup assembly 552; the fourth vertical cylinder 551 is installed on the body frame 1 and is located below the first folding box part 22; the second suction cup assembly 552 is installed on the fourth vertical cylinder 551 and moves in and out of the first folding box part 22.

[0041] When folding the bottom of the packaging box, the folding action is large, and the packaging box grasped by the first feeding robot 4 and the second feeding robot 6 is easy to shake or even fall off, which seriously affects the folding of the packaging box. By providing a first positioning component 55, the fourth vertical cylinder 551 in the first positioning component 55 can drive the second suction cup component 552 to move toward the bottom of the packaging box, and the packaging box is sucked and fixed by the second suction cup component 552, which can effectively solve the above problem.

[0042] The above-mentioned dust-proof wing bending assembly 52 also includes two second mounting seats 526, both of which are mounted on the body frame 1; a lifting rod 527, the two ends of which are respectively connected to the two second mounting seats 526, and the first mounting seat 521 is slidably fitted on the upper part of the lifting rod 527; a third mounting seat 528, which is fixed to the middle part of the lifting rod 527; and a second telescopic cylinder 529, which is mounted on the third mounting seat 528, and the piston rod of the second telescopic cylinder 529 is connected to the first mounting seat 521.

[0049] When folding the top of the packaging box, the folding action is large, and the packaging box grasped by the second feeding robot 6 is prone to shaking or even falling off, seriously affecting the folding of the packaging box. By providing a second positioning component 74, the eighth vertical cylinder 741 in the second positioning component 74 can drive the fourth suction cup component 742 to pass through the through hole 231 and move toward the bottom of the packaging box. The packaging box is sucked and fixed by the fourth suction cup component 742, which can effectively solve the above problem.

[0051] In this embodiment, the locking member 7213 is a locking bolt, which passes through the arc hole 7214 and is screwed to the fixed support 7211. When in use, by loosening the locking bolt, the locking and fixing of the movable support 7212 is released, and the angle of the movable support 7212 can be adjusted by rotating on the fixed support 7211, and the angle of the fourth bending plate 723 can be indirectly adjusted to ensure that when the fourth bending plate 723 bends the top plate downward, it is as close to the support panel 713 as possible, so that the fourth bending plate 723 can cooperate with the support panel 713 to bend a box top tongue with a good folding edge, and the angle of the box top tongue bent on the box top plate is as small as possible, so that the clamping and shaping machine 733 can smoothly clamp the bent box top tongue and clamp the box top tongue into shape.

[0052] The mounting support 721 includes two sets of locking pieces 7213. By providing two sets of locking pieces 7213, the movable support 7212 is limited, so that the locking pieces 7213 are more firmly and stably locked to the movable support 7212.
