Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, and in particular to a corrugated cardboard box production line. Background Technology

[0002] Currently, commonly used cardboard boxes are made from cardboard through processes such as printing, slotting, die-cutting, and binding. During the printing and die-cutting processes, the semi-finished cardboard coming out of the printing and slotting machine is face up, but in the next step of the stapling or gluing machine, it usually needs to be face down. In existing technology, the semi-finished cardboard is typically turned over manually (face down) before being transported to the stapling or gluing machine, and then placed on a conveyor belt for the next step. This existing technology suffers from low automation and low work efficiency. Furthermore, for some large cardboard boxes, workers can only hold the edges, making the cardboard prone to deformation during loading, affecting product quality.

[0003] Chinese Patent CN215247858U provides a plate transport assembly, comprising: a frame; a conveying assembly disposed on the frame; and a flipping assembly, including a rotating shaft assembly rotatably connected to the frame, a load member connected to the rotating shaft assembly, and a driving member drively connected to the rotating shaft assembly. The conveying assembly has several groups of load members; the load members are located between adjacent conveying assemblies, and the load members have a "Z"-shaped structure. The center position of the load member is fixedly connected to the rotating shaft assembly, and a limiting member is connected to the load member. The rotating shaft assembly is disposed on one side of the frame. The device includes a monitoring component located below the conveying assembly and mounted on the load. The monitoring component is electrically connected to the drive component. The load includes a support rod for carrying goods. The support rod is provided with several sets of roller assemblies along its axial direction. The limiting component is detachably connected to the support rod through the roller assemblies. The limiting component is provided with a buffer layer. The semi-finished cardboard coming out of the printing and slotting machine is automatically flipped by the provided flipping assembly. Then, the semi-finished cardboard is transported by the conveying assembly, saving labor costs and effectively improving the operating efficiency of the carton production process.

[0004] Existing corrugated cardboard box production lines mostly process materials separately, involving transportation, binding by binding machines, stacking by stacking machines, and then strapping by strapping machines. This process is complex, requires workers to move materials back and forth, and results in low work efficiency. Summary of the Invention

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] A corrugated cardboard box production line, see Figures 1 to 3 The system includes a transport component 1, which is the prior art proposed in the prior art document and will not be described in detail here. A machine tool 7 is provided on the side of the transport component 1. Three corrugated paper slide plates 71 are welded inside the machine tool 7, and a gap is reserved between the three corrugated paper slide plates 71. A corrugated paper pre-storage mechanism 2, an adhesive mechanism 3, a collection mechanism 5 and a binding mechanism 6 are arranged sequentially on the top of the machine tool 7. A negative pressure suction feeding mechanism 4 is arranged below the corrugated paper pre-storage mechanism 2 and the adhesive mechanism 3 on the machine tool 7.

[0022] Specifically, the corrugated paper feeding mechanism 2 and the adhesive mechanism 3 rely on negative pressure to attract the feeding mechanism 4.

[0023] See Figure 1 , Figure 2In this embodiment, the corrugated paper pre-storage mechanism 2 includes two first cylinders 21, which are mounted on the top of the machine tool 7 and aligned with two corrugated paper slide plates 71 on both sides. Alignment plates 22 are mounted on the output shafts of the two first cylinders 21, and the alignment plates 22 are located above the corrugated paper slide plates 71. A second cylinder 25 is fixedly mounted on the side of the machine tool 7, and a side alignment plate 24 is mounted on the output shaft of the second cylinder 25. A first fixing plate 23 is fixedly mounted on the top of the machine tool 7, and the first fixing plate 23 is aligned with the side alignment plate 24. A second fixing plate 26 is fixedly mounted on the side of the adhesive mechanism 3, and the second fixing plate 26 is aligned with the alignment plate 22. The height of the second fixing plate 26 is greater than the height of the alignment plate 22, which is used to block the corrugated paper. A binding machine 8 is provided on the front side of the adhesive mechanism 3. Two bundles of staples 81 are connected to the binding machine 8. The two bundles of staples 81 are collected by a conveyor roller, and the binding machine 8 automatically pulls the staples.

[0024] Specifically, the transport component 1 is tilted and launched to the position of the corrugated paper pre-storage mechanism 2, where it is blocked and collected by the second fixing plate 26. The two first cylinders 21 push the alignment plate 22 to squeeze the corrugated paper, and the second cylinder 25 pushes the side alignment plate 24 to squeeze the side of the corrugated paper, thus pre-storing the corrugated paper.

[0025] See Figure 1 , Figure 2 In this embodiment, the adhesive mechanism 3 includes a top plate 31, four support rods are fixedly installed at the bottom of the top plate 31, two third cylinders 33 are installed at the bottom of the top plate 31, the same pressing bar 32 is installed on the output shaft of the two third cylinders 33, two flip motors 35 are installed on the outer sides of the two corrugated paper slide plates 71, the same flip folding plate 36 is installed between the two flip motors 35 on the same side, a limit sensor 34 is installed at the tail end of the top plate 31, a glue box 37 is provided on the side of the machine tool 7, and a glue roller 38 is connected to the glue box 37. The glue roller 38 is rotatable.

[0026] Specifically, the negative pressure pump 43 operates, causing the negative pressure suction head 42 to generate negative pressure to attract and fix the corrugated paper. Two electric lead screw slide rails 44 drive the corrugated paper to move through the negative pressure hollow plate 41 and the negative pressure suction head 42, moving the corrugated paper from the bottom to the position of the gluing mechanism 3 (the bottom corrugated paper is being transported). During the movement of the corrugated paper, glue is applied to one bottom side of the corrugated paper by the glue roller 38, and the glue box 37 supplies glue to the glue roller 38. The position is sensed by the limit sensor 34, which plays a limiting role. Four flip motors 35 work simultaneously, driving two flip folding plates 36 to fold the corrugated paper in half, so that the glued side is at the bottom edge and the unglued side is at the top. Two third cylinders 33 drive the pressing strip 32 to move downward, sealing and pressing the two sides of the corrugated paper to make it glued. After gluing, the corrugated paper continues to be conveyed. During the conveying, the binding machine 8 uses two bundles of staples 81 to bind the glued position of the corrugated paper (binding is existing technology).

[0027] See Figure 1 , Figure 3 In this embodiment, the negative pressure suction feeding mechanism 4 includes two electric lead screw slide rails 44, both of which are installed on the bottom sides of the machine tool 7. A negative pressure hollow plate 41 is installed between the two electric lead screw slide rails 44. A negative pressure pump 43 is connected to the negative pressure hollow plate 41. The negative pressure pump 43 has a built-in pressure gauge. Multiple negative pressure suction heads 42 are connected to the negative pressure hollow plate 41. The negative pressure suction heads 42 are located between three corrugated paper slide plates 71 and are used to attract and convey the corrugated paper.

[0028] In this embodiment, the collecting mechanism 5 includes two fourth cylinders 52, a horizontal plate 55, and two electric telescopic plates 56. The horizontal plate 55 is fixedly installed on the top plate 31. Two roller supports 54 are fixedly installed at the bottom of the horizontal plate 55. Two sets of conveying rollers 53 are symmetrically rotated between the two roller supports 54. The two fourth cylinders 52 are installed on the top sides of the machine tool 7. Side limiting plates 51 are installed on the output shafts of the two fourth cylinders 52. The two side limiting plates 51 are symmetrically arranged. The two electric telescopic plates 56 are located between three corrugated paper slide plates 71. The two electric telescopic plates 56 are used to block the corrugated paper. The two electric telescopic plates 56 can extend and retract. An electric push plate 57 is fixedly installed at the bottom of the horizontal plate 55. The electric push plate 57 is located in front of the two sets of conveying rollers 53.

[0029] Specifically, two sets of conveyor rollers 53 deliver corrugated paper between two side limiting plates 51, and two electric telescopic plates 56 block and limit it. The corrugated paper passes under the electric push plate 57, and multiple corrugated papers are inserted from the bottom, so that multiple corrugated papers gradually stack up.

[0030] In this embodiment, the binding mechanism 6 includes a transverse plate 61 and two conveyor belts 63. Four straight rods are installed at the bottom of the transverse plate 61, and all four straight rods are installed at the top of the machine tool 7. Two fifth cylinders 67 are installed at the bottom of the transverse plate 61, and the same clamping plate 62 is installed on the output shaft of the two fifth cylinders 67. Two rope rollers 68 are provided at the top of the transverse plate 61, and binding ropes 65 are connected to both rope rollers 68. Binding arms 69 are installed on both sides of the machine tool 7, and the two binding arms 69 cooperate with the two binding ropes 65. The two conveyor belts 63 are installed on the inner side of the machine tool 7, and two end limiting plates 64 are installed between the two conveyor belts 63. The two end limiting plates 64 are symmetrically arranged and used to bind and limit the corrugated paper (corrugated paper binding is prior art).

[0031] Operating Procedure: During use, the power supply and controller are connected. Corrugated paper is conveyed via transport component 1, which is tilted and launched to the pre-storage mechanism 2. It is then collected and blocked by the second fixing plate 26. Two first cylinders 21 push the alignment plate 22 to compress the corrugated paper, while the second cylinder 25 pushes the side alignment plate 24 to compress the sides of the corrugated paper. The negative pressure pump 43 operates, causing the negative pressure suction head 42 to generate negative pressure, attracting and fixing the corrugated paper. Two electric lead screw slides 44 are driven by the negative pressure hollow plate 41 and the negative pressure suction head 42. The corrugated paper moves to the position of the gluing mechanism 3. During the movement, glue is applied to one bottom side of the corrugated paper by the glue roller 38, and the glue box 37 supplies glue to the glue roller 38. The position is sensed by the limit sensor 34, which acts as a limit. Four flip motors 35 work simultaneously, driving two flip folding plates 36 to fold the corrugated paper in half, with the glued side at the bottom and the un-glueed side at the top. Two third cylinders 33 drive the pressing strip 32 downward to seal and press the two sides of the corrugated paper together. After the adhesive is applied, the corrugated paper continues to be conveyed. During conveying, the binding machine 8 uses two bundles of staples 81 to bind the adhesive position of the corrugated paper. Then, the corrugated paper is sent between two side limiting plates 51 by two sets of conveying rollers 53. The two electric telescopic plates 56 block and limit the movement. The corrugated paper passes under the electric push plate 57. Multiple pieces of corrugated paper are inserted from the bottom, so that multiple pieces of corrugated paper gradually stack up. After reaching a suitable number, the two electric telescopic plates 56 retract, and the electric push plate 57 pushes multiple pieces of corrugated paper into the binding machine. At position 6, the corrugated paper is pre-wrapped by two binding ropes 65. Two fifth cylinders 67 push the pressing plate 62 downward to press multiple pieces of corrugated paper together. Two binding arms 69 drive the two binding ropes 65 downward to cooperate with two joints to bind multiple pieces of corrugated paper. The joints of the two binding ropes 65 are left inside the machine tool 7 for the next binding of corrugated paper. The corrugated paper is existing technology and will not be described in detail here. After binding, the corrugated paper is transported away by two sets of conveyor belts 63. At the same time, the corrugated paper continues to be processed without stopping the machine.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
