Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard processing equipment, and in particular to a device for breaking up stacked corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a widely used packaging paperboard. Currently, corrugated cardboard is typically produced by cutting continuous sheets of corrugated cardboard, creased seams, and partially cut transition joints to create large-format corrugated cardboard. This is followed by stacking the cardboard into piles, where manual intervention is required to break the transition joints of each pile into smaller piles. These smaller piles are then further processed through strapping and stacking. However, this manual process of breaking the transition joints is inefficient and heavily reliant on manual labor. Summary of the Invention

[0003] The purpose of this invention is to provide a device for breaking up stacked corrugated cardboard.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A stacking breaking device for corrugated cardboard includes a breaking main unit. The breaking main unit has a stacking pressing structure on the infeed side and a breaking structure on the outfeed side. The stacking pressing structure includes a main unit base, a stacking lifting seat, a first conveying structure, an upper offset driving structure, and a lower offset driving structure. The main unit base has two opposing main substrates and a first connecting rod connecting the bottom of the two main substrates. Each main substrate has a base section extending from its bottom toward the outfeed side. The stacking lifting seat is vertically and vertically positioned between the tops of the two main substrates. The first conveying structure is positioned above the first connecting rod. The upper offset driving structure has a fixed end and a telescopic driving end. The fixed end is fixed to the tops of the two main substrates, and the telescopic driving end extends to the outfeed side and is hinged to the top of the breaking structure. The lower offset driving structure is positioned between the first conveying structure and the first connecting rod and is hinged to the bottom of the breaking structure.

[0006] The stacking structure includes a tilting base, a stacking lifting seat, and a second conveying structure. The tilting base has two tilting base plates arranged opposite each other and a second connecting rod connected between the bottoms of the two tilting base plates. Each tilting base plate has a clamping plate section at its bottom that abuts against a base section. The stacking lifting seat is vertically and vertically positioned between the tops of the two tilting base plates. The second conveying structure is horizontally positioned above the second connecting rod, corresponding to the first conveying structure, to transport the corrugated cardboard stack to the first and second conveying structures. When the transition connecting section of the corrugated cardboard stack is located between the first and second conveying structures, the stacking lifting seat and the stacking lifting seat descend to press against both ends of the corrugated cardboard stack. With the operation of the upper offset driving structure, the lower offset driving structure, and the second conveying structure, the corrugated cardboard stack is broken along the transition connecting section, and the second conveying structure outputs the stacked pieces.

[0007] As a further technical solution of the present invention: both the main substrate and the sway substrate have a lifting guide port that communicates with the outside on their top and a lifting drive cylinder at the bottom of their outer side. The telescopic rod of the lifting drive cylinder is hinged to one end of the stacking lifting seat or the breaking lifting seat, so that the telescopic rod of the lifting drive cylinder can extend and retract, thereby driving the stacking lifting seat or the breaking lifting seat to rise and fall.

[0008] As a further technical solution of the present invention: the main substrate and the oscillating substrate are provided with two guide rails parallel to the lifting guide port and a rack rail connected to one side of the lifting guide port and parallel to the lifting guide port on their inner side. The stacking lifting seat and the stacking lifting seat are provided with a slider that can slide along the guide rail at each end corresponding to each guide rail and a balance shaft that meshes with the rack rail is rotatably provided on their top.

[0009] As a further technical solution of the present invention: the upper offset driving structure includes two opposing fixed plates and a synchronous rod connecting the two fixed plates extending to the unloading side. A pad is provided between the end of the fixed plate facing the loading side and the main base plate, and bolts are inserted into the fixed plate, the pad and the main base plate in sequence to fix the fixed plate. The end of the fixed plate extending to the unloading side extends out of the stacking structure and a cylinder seat is provided on the side facing the stacking structure. An upper offset driving cylinder is provided on the cylinder seat. The telescopic rod of the upper offset driving cylinder is inserted between the top of the stacking structure and the fixed plate and is hinged to the top of the stacking structure. The telescopic rod of the upper offset driving cylinder extends and retracts, causing the top of the stacking structure to offset and swing.

[0010] As a further technical solution of the present invention: the first connecting rod is located below the second connecting rod, and two fixed seats are provided on the first connecting rod opposite to each other, and the first conveying structure is disposed above the top of the two fixed seats.

[0011] As a further technical solution of the present invention: the lower offset driving structure includes two lower offset driving cylinders arranged opposite to each other. Each lower offset driving cylinder is correspondingly arranged in a fixed seat, and the telescopic rod of the lower offset driving cylinder is hinged to one end of the second connecting rod, so that the telescopic rod of the lower offset driving cylinder can extend and retract, thereby driving the bottom of the stacking structure to offset and swing.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention proposes a whole stack breaking device for corrugated cardboard after stacking. Through the cooperation between the pressing structure and the breaking structure, when the transition connection section of the corrugated cardboard stack is located between the first conveying structure and the second conveying structure, the pressing lifting seat and the breaking lifting seat descend to press against the two ends of the corrugated cardboard stack respectively. With the operation of the upper offset driving structure, the lower offset driving structure and the second conveying structure, the corrugated cardboard stack is broken along the transition connection section, and the second conveying structure outputs the stacked pieces, effectively improving the breaking and stacking efficiency of the corrugated cardboard stack.

The second conveying structure 123 is horizontally positioned above the second connecting rod 42, corresponding to the first conveying structure 113, for conveying the corrugated cardboard stack to the first conveying structure 113 and the second conveying structure 123. When the transition connecting section of the corrugated cardboard stack is located between the first conveying structure 113 and the second conveying structure 123, the stacking lifting seat 112 and the stacking lifting seat 122 descend to press against both ends of the corrugated cardboard stack, respectively. (See reference...) Figures 4-8 With the operation of the upper offset drive structure 114, the lower offset drive structure 115 and the second conveying structure 123, the corrugated cardboard stack is broken along the transition connection section, and the second conveying structure 123 outputs the stacked cardboard.

[0024] Furthermore, in this embodiment, both the main substrate 21 and the sway substrate 41 have a lifting guide port 101 that communicates with the outside on their top and a lifting drive cylinder 102 at the bottom of their outer side. The telescopic rod of the lifting drive cylinder 102 is hinged to one end of the stacking lifting seat 112 or the breaking lifting seat 122, so that the telescopic rod of the lifting drive cylinder 102 can extend and retract, thereby driving the stacking lifting seat 112 or the breaking lifting seat 122 to rise and fall.

[0025] Furthermore, in this embodiment, both the main substrate 21 and the sway substrate 41 are provided with two guide rails 103 parallel to the lifting guide port 101 and a rack rail 104 connected to one side of the lifting guide port 101 and parallel to the lifting guide port 101 on their inner side tops.

[0026] Furthermore, in this embodiment, the upper offset driving structure 114 includes two opposing fixed plates 31 and a synchronous rod 32 connecting the two fixed plates 31 extending to the end of the stacking side. A pad 311 is provided between the end of the fixed plate 31 facing the stacking side and the main base plate 21. Bolts are sequentially inserted into the fixed plate 31, the pad 311 and the main base plate 21 to form the fixed end 301, fixing the fixed plate 31.

The telescopic rod of the upper offset driving cylinder 313 extends and retracts, driving the top of the stacking structure 12 to offset and swing.

[0027] Furthermore, in this embodiment, the first connecting rod 22 is located below the second connecting rod 42, and two fixing seats 221 are provided on the first connecting rod 22 opposite to each other. The first conveying structure 113 is disposed above the top of the two fixing seats 221.

[0028] Furthermore, in this embodiment, the lower offset driving structure 115 includes two lower offset driving cylinders 51 arranged opposite to each other. Each lower offset driving cylinder 51 is correspondingly arranged in a fixed seat 221, and the telescopic rod of the lower offset driving cylinder 51 is hinged to one end of the second connecting rod 42, so that the telescopic rod of the lower offset driving cylinder 51 can extend and retract, thereby driving the bottom of the stacking structure 12 to offset and swing.

[0029] Furthermore, several reinforcing rods 61 are connected between the tops of the two main substrates 21 and between the tops of the two yaw substrates 41 to improve the stability of the main base 111 and the yaw base 121.

[0030] Understandably, the method of using the stack-breaking device for corrugated cardboard of the present invention is as follows: the stack of corrugated cardboard is input into the breaking host 10, see reference. Figure 8 One end of the corrugated cardboard stack is fed from the first conveyor structure 113 onto the second conveyor structure 123. When the transition connecting section of the corrugated cardboard stack moves between the first conveyor structure 113 and the second conveyor structure 123, the stacking lifting seat 112 and the stack breaking lifting seat 122 descend to press against both ends of the corrugated cardboard stack, respectively. (See also...) Figure 6 , Figure 7 With the operation of the upper offset drive structure 114, the lower offset drive structure 115, and the second conveying structure 123, that is, the extension and retraction of the telescopic rod of the upper offset drive cylinder 313 drives the top of the stacking structure 12 to offset and swing, and the extension and retraction of the telescopic rod of the lower offset drive cylinder 51 drives the bottom of the stacking structure 12 to offset and swing, breaking the corrugated cardboard stack along the transition connection section; see reference Figure 4 The second conveyor structure 123 will then output the stacked corrugated cardboard. In this way, the breaking and stacking of the corrugated cardboard stack is completed.

[0031] In summary, the stack breaking device for corrugated cardboard after stacking, through the cooperation between the pressing structure 11 and the breaking structure 12, enables the pressing lifting seat 112 and the breaking lifting seat 122 to descend and press against both ends of the corrugated cardboard stack when the transition connection section of the corrugated cardboard stack is located between the first conveying structure 113 and the second conveying structure 123. With the operation of the upper offset driving structure 114, the lower offset driving structure 115 and the second conveying structure 123, the corrugated cardboard stack is broken along the transition connection section, and the second conveying structure 123 outputs the separated stack, effectively improving the breaking and separating efficiency of the corrugated cardboard stack.
