[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0039] Example 1

[0040] Reference Figures 1 to 4 As shown, a sheet-like packaging box assembly device of the present invention includes: a first conveying component 3, including a first conveying member 37 for conveying a packaging box 1 to be assembled, the first conveying member 37 having a first stop 39 that moves with the first conveying member 37, and a conveying space for accommodating the packaging box 1 to be assembled being formed between adjacent first stop 39s, the distance between adjacent first stop 39s being not less than the width of the bottom plate 11 of the packaging box 1 to be assembled, so that the packaging box 1 to be assembled is U-shaped in the conveying space; and an assembly mechanism, including a plurality of assembly components arranged sequentially along the conveying direction of the first conveying member 37, the plurality of assembly components being capable of assembling the packaging box 1 to be assembled.

[0041] In this embodiment of the sheet-like packaging box assembly device, the initial state of the packaging box 1 to be assembled is sheet-like. After the packaging box 1 to be assembled is inserted between the first stop blocks 39, the bottom plate 11 of the packaging box 1 to be assembled cooperates with the first stop blocks 39, so that the packaging box 1 to be assembled is U-shaped as a whole. The first conveying component 37 can drive the packaging box 1 to be assembled to move. The packaging box 1 to be assembled passes through multiple assembly components of the assembly mechanism. After the multiple assembly components fold the packaging box 1 to be assembled, the assembly of the packaging box 1 to be assembled is completed. Thus, the sheet-like packaging box assembly device of this embodiment can complete the overall assembly from the sheet-like packaging box 1 to be assembled. At the same time, the sheet-like packaging box assembly device occupies a small area and has high packaging box assembly efficiency.

[0042] Reference Figure 5 As shown, the initial state of the packaging box 1 to be assembled is sheet-like, including a bottom plate 11, a top plate 14, a first side plate 12, and a second side plate 13. The first side plate 12 is connected between the bottom plate 11 and the top plate 14, and the second side plate 13 is connected to the bottom plate 11. An adhesive portion 19 is provided on the side of the second side plate 13 away from the bottom plate 11. A first flap 15 is provided at one end of the first side plate 12 and the second side plate 13, and a second flap 16 is provided at the other end. A first end plate 17 is provided at one end of the top plate 14 and the bottom plate 11, and a second end plate 18 is provided at the other end. Indentations are provided at the connection points between the above components to facilitate folding.

[0043] Reference Figure 6 and Figure 7As shown, the feeding assembly 2 includes a second conveyor 21 and baffles 22. The second conveyor 21 can be considered as a conveyor belt device. The baffles 22 are arranged parallel to each other and opposite to each other. The second conveyor 21 is located between the two baffles 22. The baffles 22 form a feeding space for accommodating the packaging box 1 to be assembled. The sheet-shaped packaging box 1 to be assembled is located vertically in the feeding space, and the adhesive part 19 is in contact with the second conveyor 21. Preferably, a second stop 23 is provided at one end of the baffle 22 near the first conveyor assembly 37. The second stop 23 extends in the opposite direction of the baffle 22, and the distance between the second stop 23 is less than the width of the packaging box 1 to be assembled, but the packaging box 1 to be assembled can be pulled out between the second stop 23 after slight bending. There are multiple second stop 23s arranged at equal intervals. The end of the baffle 22 near the first conveyor 37 is inclined towards the first conveyor 37, so that the packaging box 1 to be assembled located in the feeding space near the end of the first conveyor 37 is inclined towards the first conveyor 37. Preferably, the feeding assembly 2 further includes a third support plate 29 disposed opposite to each other, with the baffle 22 and the second conveyor 21 located between the third support plates 29. Two lead screws are rotatably connected between the third support plates 29, with the movable nut of one lead screw connected to the two baffles 22 and the movable nut of the other lead screw connected to the second conveyor 21. A slide rod is also connected between the third support plates 29 and slidably connected to the baffles 22 and the second conveyor 21. Handwheels are connected to the ends of the two lead screws respectively. By rotating the handwheels, the positions of the baffles 22 and the second conveyor 21 can be adjusted, so that the feeding assembly 2 can be used to accommodate packaging boxes 1 of different sizes to be assembled.

[0044] The feeding assembly 2 also includes a sixth driving member 24. The output end of the sixth driving member 24 is connected to a third connecting rod 28 and can drive the third connecting rod 28 to rotate. Specifically, the sixth driving member 24 can be regarded as a cylinder. The output end of the sixth driving member 24 is hinged to a first hinge member 25. The end of the sixth driving member 24 away from the output end is hinged to the outside. The end of the first hinge member 25 is sleeved on the third connecting rod 28 and fixedly connected to the third connecting rod 28, so that the sixth driving member 24 can drive the third connecting rod 28 to rotate. A connecting plate 26 is sleeved on the third connecting rod 28. The connecting plate 26 is provided with a plurality of adsorption members 27 connected to a vacuum source. The connecting plate 26 rotates with the third connecting rod 28 and can drive the adsorption members 27 to extend into the feeding space. The adsorption members 27 can adsorb the packaging box 1 to be assembled at the output end of the feeding space, and then the packaging box 1 to be assembled is pulled out between the second stops 23 by the rotation of the third connecting rod 28. In another embodiment, the sixth drive member 24 can be regarded as a motor, and the output end of the sixth drive member 24 is connected to the end of the third link 28, thereby causing the third link 28 to rotate.

[0045] The first conveying assembly 3 includes a first conveyor 37 for conveying the packaging box 1 to be assembled. The first conveyor 37 can be considered as a chain mechanism, and one side of the first conveyor 37 used for conveying the packaging box 1 to be assembled is flat. A first stop 39 is provided on the side of the first conveyor 37 used for conveying the packaging box 1 to be assembled, so that the first stop 39 can move with the first conveyor 37. The adjacent first stop 39 form a conveying space for accommodating the packaging box 1 to be assembled. Specifically, there are two first conveyors 37 arranged opposite to each other. The first stop 39 includes an abutment surface for contacting the packaging box 1 to be assembled. The abutment surface is flat, and the abutment surfaces are arranged opposite to each other within the conveying space. Four first stop 39s constitute one conveying space, and the adjacent conveying spaces are separated by a certain distance. The distance between adjacent first stops 39 within the conveying space is not less than the width of the bottom plate 11 in the packaging box 1 to be assembled. Specifically, the sixth driving component 24 can drive the adsorption component 27 to pass between the first conveying components 37, thereby allowing the packaging box 1 to be assembled to be located within the conveying space. The distance between the first stops 39 is slightly greater than the width of the bottom plate 11 of the packaging box 1 to be assembled, so that during the process of the packaging box 1 entering the conveying space, the packaging box 1 to be assembled is configured as follows: Figure 9 As shown in the U-shaped posture, after the bottom plate 11 of the packaging box 1 to be assembled is attached to the first conveyor 37, the adsorption component 27 stops adsorbing the packaging box 1 to be assembled. Until the first conveyor 37 drives the packaging box 1 to be assembled to move outside the moving path of the adsorption component 27, the sixth drive component 24 drives the adsorption component 27 to move towards the upward material space for the next loading and transportation of the packaging box 1 to be assembled.

[0046] The first conveying assembly 3 also includes a ninth driving member 33. The output end of the ninth driving member 33 is connected to the first conveying member 37 via a transmission wheel, thereby enabling the ninth driving member 33 to drive the first conveying member 37 to move. The first conveying member 37 has side plates 31 on its two farthest sides. A fourth guide plate 38 is connected to the side plate 31 along the conveying direction of the first conveying member 37 via a first guide bracket. The end of the fourth guide plate 38 near the input end of the first conveying member 37 has an inclined surface that is inclined in the conveying direction of the first conveying member 37. The inclined surfaces of the two fourth guide plates 38 are symmetrically arranged. During the process of the first conveying member 37 driving the packaging box 1 to be assembled to move, the inclined surfaces of the fourth guide plates 38 can cause the first rocker wings 15 and the second rocker wings 16 at both ends of the first side plate 12 to fold towards the internal space of the packaging box 1 to be assembled.

[0047] The first conveying assembly 3 also includes a tenth driving member 34 and a second support plate 32 disposed opposite to it. The first conveying member 37 is located between the second support plates 32. The tenth driving member 34 is connected to the second support plate 32. The output end of the tenth driving member 34 is connected to a transmission member 35, which can be regarded as a lead screw. The transmission member 35 passes through the first conveying member 37 and is connected to it in cooperation with the first conveying member 37. That is, the movable nut of the transmission member 35 is connected to the first conveying member 37, so that the tenth driving member 34 can drive the first conveying member 37 to move along the transmission member 35. A guide rod 36 is also connected between the second support plates 32. The first conveying member 37 is slidably connected to the guide rod 36, so that the position of the first conveying member 37 is adjustable. The tenth driving member 34 can be regarded as a handwheel or a motor. Preferably, the ninth driving member 33 is connected to the second support plate 32, and the transmission wheel is slidably connected to the output shaft of the ninth driving member 33. That is, the ninth driving member 33 can drive the first conveyor 37 to move, and the first driving member 74 can slide along the output shaft of the ninth driving member 33. The way the ninth driving member 33 is connected to the second support plate 32 makes the overall weight of the first conveyor 37 lower.

[0048] The assembly mechanism is used to fold the packaging box 1 to be assembled multiple times to complete the assembly of the packaging box 1. The assembly mechanism includes multiple assembly components arranged sequentially along the conveying direction of the first conveyor 37. The multiple assembly components can complete the assembly of the packaging box 1 to be assembled. Specifically, the assembly mechanism includes a first assembly component 4, a second assembly component 5, a third assembly component 7, and a fourth assembly component 8 arranged sequentially along the conveying direction of the first conveyor 37. The packaging box 1 to be assembled is folded four times by the first assembly component 4, the second assembly component 5, the third assembly component 7, and the fourth assembly component 8 to complete the assembly of the packaging box 1 to be assembled.

[0049] Reference Figure 8 and Figure 9As shown, the first assembly component 4 is disposed opposite to both sides of the first conveyor 37. The first assembly component 4 includes a fourth drive component 41, which is connected to the side plate 31 via a first mounting base 42. The output end of the fourth drive component 41 is connected to a first connecting rod 45 and can drive the first connecting rod 45 to rotate. Specifically, the fourth drive component 41 can be regarded as a cylinder. The output end of the fourth drive component 41 is hinged to a second hinge component 43, which is connected to the first connecting rod 45 via a seventh connecting rod 44. At the same time, the second hinge component 43 is hinged to the first mounting base 42, and the end of the fourth drive component 41 away from the output end intersects with the first mounting base 42, thereby enabling the fourth drive component 41 to drive the first connecting rod 45 to rotate. The driving direction of the fourth drive component 41 is perpendicular to the conveying direction of the first conveyor 37, and the seventh connecting rod 44 is perpendicularly connected to the first connecting rod 45, thereby making the rotation axis of the first connecting rod 45 parallel to the conveying direction of the first conveyor 37. When the first conveyor 37 moves the packaging box 1 to be assembled into the working range of the first assembly component 4, the fourth drive component 41 can drive the first connecting rod 45 to rotate, thereby causing the first end plate 17 and the second end plate 18 at both ends of the base plate 11 to fold away from the internal space of the packaging box 1, preventing the warping of the first end plate 17 and the second end plate 18 from affecting the subsequent folding process. In another embodiment, the fourth drive component 41 can be regarded as a motor, and the output end of the fourth drive component 41 is connected to the second hinge component 43, thereby enabling the fourth drive component 41 to drive the first connecting rod 45 to rotate. In another embodiment, the fourth drive component 41 can be regarded as a cylinder, with the position of the fourth drive component 41 higher than the first conveyor 37, and the output end of the fourth drive component 41 facing the movement path of the first end plate 17 and the second end plate 18 at both ends of the base plate 11, thereby enabling the output end of the fourth drive component 41 to directly drive the first end plate 17 and the second end plate 18 at both ends of the base plate 11 to fold away from the internal space of the packaging box 1. The arrangement of the first assembly component 4 is not limited to the above embodiments.

[0050] Reference Figure 10As shown, the second assembly component 5 is disposed opposite to both sides of the first conveyor 37. The second assembly component 5 includes a fifth drive component 51, which is connected to the second mounting base 52. The output end of the fifth drive component 51 is connected to a second connecting rod 53. The second connecting rod 53 is rotatable, and its rotation axis is perpendicular to the conveying direction of the first conveyor 37. The connection method between the fifth drive component 51 and the second connecting rod 53 is the same as that between the fourth drive component 41 and the first connecting rod 45, except that the rotation axes of the first connecting rod 45 and the second connecting rod 53 are different, which will not be described in detail. When the first conveyor 37 moves the packaging box 1 to be assembled into the working range of the second assembly component 5, the fifth drive component 51 can drive the second connecting rod 53 to rotate, thereby causing the first rocker wings 15 and the second rocker wings 16 at both ends of the second side plate 13 to fold towards the interior space of the packaging box 1 to be assembled. The second assembly component 5 is located at the end of the fourth guide plate 38 with an inclined slope. When the packaging box 1 to be assembled moves between the fourth guide plates 38, both the first wing 15 and the second wing 16 of the packaging box 1 to be assembled fold towards the internal space of the packaging box 1. The fourth guide plate 38 is configured to prevent the first wing 15 and the second wing 16 from opening away from the internal space of the packaging box 1 to be assembled.

[0051] Reference Figure 11 and Figure 12 As shown, when the packaging box needs to package goods, it also includes an opening component 6. The opening component 6 is used to open the wing at one end of the packaging box 1 to be assembled. The opening component 6 is arranged opposite to the second assembly component 5, and the second assembly component 5 is provided between the opening component 6 and the third assembly component 7. When the packaging box 1 to be assembled moves between the second assembly component 5 and the opening component 6, the second assembly component 5 folds the wing at one end of the packaging box 1 to be assembled, and the opening component 6 opens the wing at the other end of the packaging box 1 to be assembled. The goods to be packaged are transported from the outside to the internal space of the packaging box 1 through the wing at the opened end. Then the packaging box 1 to be assembled continues to move. When it passes the second assembly component 5 between the opening component 6 and the third assembly component 7, the second assembly component 5 cooperates with the fourth guide plate 38 to fold the opened end of the wing of the packaging box 1 to be assembled.

[0052] The opening assembly 6 includes a seventh drive member 61. The output end of the seventh drive member 61 is connected to a fourth link 63. The seventh drive member 61 can drive the fourth link 63 to rotate. The fourth link 63 is connected to a second guide plate 64 that can extend into the conveying space. The second guide plate 64 can rotate towards the input end of the first conveyor 37. Specifically, the seventh drive member 61 can be regarded as a cylinder. The seventh drive member 61 is connected to the side plate 31 through a third mounting base 62. The output end of the seventh drive member 61 intersects with a third hinge member 621. The end of the seventh drive member 61 away from the output end is hinged to the third mounting base 62. At the same time, the third hinge member 621 is hinged to the third mounting base 62 and connected to the fourth link 63, so that the seventh drive member 61 can drive the fourth link 63 to rotate, thereby driving the second guide plate 64 to rotate. In another embodiment, the seventh drive member 61 is regarded as a motor. The output end of the seventh drive member 61 is connected to the fourth link 63, thereby driving the fourth link 63 to rotate.

[0053] The opening assembly 6 also includes an eighth drive member 65, which is symmetrically arranged with the seventh drive member 61. The eighth drive member 65 is connected to the fourth mounting base 66, and its output end is connected to a fifth link 67. The eighth drive member 65 can drive the fifth link 67 to rotate. The fifth link 67 is connected to a third guide plate 68 that can extend into the conveying space. The third guide plate 68 can rotate in the conveying direction of the first conveyor 37. The connection method between the eighth drive member 65 and the fifth link 67 is the same as the connection method between the seventh drive member 61 and the fourth link 63, and will not be described again. The eighth drive member 65 is located between the seventh drive member 61 and the second assembly assembly 5, thereby causing the second guide plate 64 and the third guide plate 68 to rotate in a direction away from each other within the conveying space. This causes the flap at one end of the packaging box 1 to fold away from the internal space of the packaging box 1, allowing the goods to be packaged to enter the internal space of the packaging box 1. Preferably, the opening assembly 6 further includes a first support plate 69, which is connected to the side plate 31. The plane of the first support plate 69 is parallel to the conveying surface of the first conveyor 37, so that the goods to be packaged can enter the internal space of the packaging box 1 from the outside through the first support plate 69. The first support plate 69 can support the goods to be packaged. Preferably, the maximum distance between the third guide plate 68 and the first support plate 69 is greater than the maximum distance between the second guide plate 64 and the first support plate 69, that is, the height of the third guide plate 68 is greater than the height of the second guide plate 64. This allows the third guide plate 68 to drive the rocker to fold away from the internal space of the packaging box 1, and at the same time, it can also drive the end plate at one end of the top plate 14 to fold away from the internal space of the packaging box 1, preventing the top plate 14 and the end plate from obstructing the goods to be packaged from entering the internal space of the packaging box 1. Preferably, the third mounting base 62 and the fourth mounting base 66 are slidably connected to the slide rod, the end of the slide rod is connected to the side wall, and the third mounting base 62 and the fourth mounting base 66 can be fixed to the slide rod by fastening screws, so that the opening assembly 6 can fit the packaging box 1 of different sizes to be assembled.

[0054] Reference Figures 13 to 15 As shown, the third assembly component 7 includes a first drive member 74, a pressure plate 75, and a first guide plate 73, wherein both the first drive member 74 and the first guide plate 73 are connected to the fifth mounting base 72. The first guide plate 73 is bent in the conveying direction of the first conveyor 37. Specifically, the first guide plate 73 extends towards the input end of the first conveyor 37 via a second guide bracket. The first drive member 74 is located on the side of the first guide plate 73 near the output end of the first conveyor 37. The pressure plate 75 is connected to the output end of the first drive member 74. The first drive member 74 can be considered as a cylinder, capable of driving the pressure plate 75 to move towards or away from the first conveyor 37.

[0055] The third assembly component 7 also includes an eleventh drive component 71, which is connected to the side plate 31 via a sixth mounting base 713, and is positioned opposite to the first conveyor component 37 on both sides. The output end of the eleventh drive component 71 is connected to a sixth link 711, enabling the eleventh drive component 71 to rotate. The axis of rotation of the sixth link 711 is perpendicular to the conveying direction of the first conveyor component 37. The connection method between the eleventh drive component 71 and the sixth link 711 is the same as the connection method between the seventh drive component 61 and the fourth link 63, and will not be described again. The end of the sixth link 711 is connected to a fifth guide plate 712, which includes a right-angle bend, meaning the fifth guide plate 712 is generally L-shaped. The bending position of the fifth guide plate 712 forms a slot, and the eleventh driving member 71 can drive the fifth guide plate 712 to rotate towards the adhesive part 19. When the fifth guide plate 712 passes the adhesive part 19, it can drive the adhesive part 19 to fold towards the internal space of the packaging box 1 to be assembled.

[0056] The fifth mounting base 72 is also connected to a first adhesive spraying component 76, the spraying end of the first adhesive spraying component 76 facing the moving path of the adhesive part 19. When the packaging box 1 to be assembled passes the third assembly component 7, the top plate 14 gradually folds towards the internal space of the packaging box 1 along the first guide plate 73 until it moves to the position of the pressure plate 75. When the adhesive part 19 passes the first adhesive spraying component 76, the first adhesive spraying component 76 sprays adhesive towards the side of the adhesive part 19 away from the internal space of the packaging box 1. After the adhesive spraying is completed, the eleventh drive component 71 drives the fifth guide plate 712 to rotate, thereby driving the adhesive part 19 to fold. Then the first drive component 74 drives the pressure plate 75 to move towards the first conveyor component 37, thereby making the top plate 14 and the adhesive part 19 stick together and bond. Preferably, a first guide block 751 is rotatably connected to the side of the pressure plate 75 near the first conveyor 37. The first guide block 751 is located near the first guide plate 73. The first guide block 751 is generally L-shaped and its end extends towards the first conveyor 37. A second guide block 752 is also provided on the side of the pressure plate 75 near the first conveyor 37. The second guide block 752 is perpendicular to the pressure plate 75 and bends towards the conveying direction of the first conveyor 37 on the side of the second guide block 752 near the first conveyor 37. The distance between the first guide block 751 and the second guide block 752 matches the size of the packaging box 1 to be assembled. When the top plate 14 moves towards the first conveyor 37, the second guide block 752 fits against the first side plate 12, and the first guide block 751 fits against the second side plate 13, so that the adhesive position will not shift due to the tilt of the first side plate 12 and the second side plate 13 when the top plate 14 is attached to the adhesive part 19. Preferably, the fifth mounting base 72 is further provided with a lead screw, which is rotatably connected to the fifth mounting base 72. The rotating nut of the lead screw is connected to a fixed base 78. The fixed base 78 is slidably connected to the fifth mounting base 72 with multiple sliding rods. The ends of the sliding rods are connected to a pressure plate 75. The fixed base 78 is fixed to the outside. The fifth mounting base 72 is provided with a twelfth driving member 77 connected to the lead screw. The twelfth driving member 77 can drive the lead screw to rotate, thereby driving the fifth mounting base 72 to move towards or away from the first conveying member 37, so that the third assembly component 7 can be adapted to packaging boxes 1 of different sizes to be assembled. Preferably, it also includes a thirteenth driving member 761, which is connected to the fifth mounting base 72. The output end of the thirteenth driving member 761 is connected to the first adhesive spraying member 76. The thirteenth driving member 761 can drive the first adhesive spraying member 76 to move along the edge of the fifth mounting base 72, so that the position of the first adhesive spraying member 76 is adjustable and adapted to the adhesive part 19 at different positions.

[0057] Reference Figure 16 and Figure 17As shown, the fourth assembly component 8 is disposed opposite to both sides of the first conveyor 37. The fourth assembly component 8 includes a second drive component 81 and a third drive component 83. The output end of the second drive component 81 is connected to the first tilting plate 82 and can drive the first tilting plate 82 to rotate. The output end of the third drive component 83 is connected to the second tilting plate 84 and can drive the second tilting plate 84 to rotate. The driving method of the second drive component 81 and the first tilting plate 82 is the same as the driving method of the seventh drive component 61 and the fourth connecting rod 63, and will not be described again. At the same time, the driving method of the third drive component 83 and the second tilting plate 84 is the same as the driving method of the seventh drive component 61 and the fourth connecting rod 63, and will not be described again. The first tilting plate 82 and the second tilting plate 84 are symmetrically arranged and the axis of symmetry is parallel to the conveying direction of the first conveyor 37. The first tilting plate 82 and the second tilting plate 84 can rotate in opposite directions. The side plate 31 is also connected to a second adhesive spraying component. The second adhesive spraying component is disposed opposite to both sides of the first conveyor 37. The adhesive spraying end of the second adhesive spraying component is directed toward the movement path of the first rocker 15 and the second rocker 16 at both ends of the packaging box 1 to be assembled. When the packaging box 1 to be assembled passes the fourth assembly component 8, the second adhesive spraying component can spray adhesive onto the first rocker 15 and the second rocker 16. Then, the second drive component 81 and the third drive component 83 respectively drive the first end plate 17 and the second end plate 18 at both ends of the packaging box 1 to be assembled to fold toward the internal space of the packaging box 1 to be assembled, so that the first end plate 17 is pasted with the first rocker 15 and the second end plate 18 is pasted with the second rocker 16. The third driving component 83 is located between the second driving component 81 and the first conveying component 37. Preferably, the second driving component 81 is connected to the seventh mounting base 85, the third driving component 83 is connected to the eighth mounting base 86, the eighth mounting base 86 is connected to the side plate 31, and the eighth mounting base 86 is connected to the movable base 87. The movable base 87 and the seventh mounting base 85 are slidably connected, so that the distance between the first flip plate 82 and the second flip plate 84 can be finely adjusted. The movable base 87 and the eighth mounting base 86 are connected by a screw, so that the distance between the first flip plate 82 and the second flip plate 84 can be adjusted over a wide range, thereby making the fourth assembly component 8 suitable for packaging boxes 1 of different sizes to be assembled.

[0058] The output end of the first conveying component 3 is also provided with a second conveying component 9. The second conveying component 9 includes a third conveying member, which can be regarded as a conveyor belt device. The third conveying member can move the assembled packaging box 1 to the next work station.

[0059] In this embodiment, the order in which the second assembly component 5, the third assembly component 7, and the fourth assembly component 8 are arranged is not fixed. For example, the packaging box 1 to be assembled can first pass through the third assembly component 7 to complete the gluing of the top plate 14, and then pass through the second assembly component 5 and the fourth assembly component 8 to complete the gluing of the first end plate 17 to the first rocker wing 15, and the gluing of the second rocker wing 16 to the second end plate 18. Alternatively, the packaging box 1 to be assembled can first pass through the second assembly component 5 and the fourth assembly component 8, and finally pass through the third assembly component 7.

[0060] In use, the initial state of the packaging box 1 to be assembled is sheet-like. The sheet-like packaging box 1 is located in the feeding space, and the adhesive part 19 is in contact with the second conveyor 21. The sixth drive 24 drives the adsorption member 27 to extend into the feeding space. The adsorption member 27 adsorbs the packaging box 1 to be assembled at the output end of the feeding space and rotates towards the first conveyor 37. Then, the sixth drive 24 drives the adsorption member 27 to pass between the first conveyors 37, so that the packaging box 1 to be assembled can be located in the conveying space. The packaging box 1 to be assembled is located between the first stops 39 and forms a U-shaped posture. The first conveyor 37 drives the packaging box 1 to be assembled to the first assembly component 4. The fourth drive 24 drives the packaging box 1 to be assembled to move to the first assembly component 4. 41 drives the first connecting rod 45 to rotate, thereby causing the first end plate 17 and the second end plate 18 at both ends of the base plate 11 to fold away from the internal space of the packaging box 1 to be assembled; the first conveying component 37 drives the packaging box 1 to be assembled to move to the second assembly component 5, and the fifth driving component 51 can drive the second connecting rod 53 to rotate, thereby causing the first rocker wing 15 and the second rocker wing 16 at both ends of the second side plate 13 to fold towards the internal space of the packaging box 1 to be assembled, while the inclined surface of the fourth guide plate 38 causes the first rocker wing 15 and the second rocker wing 16 at both ends of the first side plate 12 to fold towards the internal space of the packaging box 1 to be assembled; when the packaging box needs to pack goods, the opening component 6 can The wing at one end of the packaging box 1 to be assembled is opened, and the goods to be packaged are transported from the outside to the interior space of the packaging box 1 through the opened wing. The first conveyor 37 moves the packaging box 1 to the third assembly component 7. The top plate 14 gradually folds towards the interior space of the packaging box 1 along the first guide plate 73 until it moves to the position of the pressure plate 75. When the adhesive part 19 passes the first adhesive spraying component 76, the first adhesive spraying component 76 sprays adhesive onto the side of the adhesive part 19 away from the interior of the packaging box 1. After the adhesive spraying is completed, the eleventh drive component 71 drives the fifth guide plate 712 to rotate, thereby driving the adhesive part 19 to fold. Then the first drive component 74 drives the pressure plate 75 towards the first... The first conveyor 37 moves in a direction to make the top plate 14 and the adhesive part 19 adhere and bond; the first conveyor 37 drives the packaging box 1 to be assembled to the fourth assembly component 8; the second adhesive sprayer sprays adhesive onto the first rocker 15 and the second rocker 16; then the second drive 81 and the third drive 83 respectively drive the first end plate 17 and the second end plate 18 at both ends of the packaging box 1 to be assembled to fold towards the internal space of the packaging box 1, so that the first end plate 17 is bonded to the first rocker 15 and the second end plate 18 is bonded to the second rocker 16, thereby completing the overall assembly of the packaging box 1; finally, the assembled packaging box 1 is transported to the next work station by the third conveyor.
