[0033] Referring to the accompanying Figure 2 - the accompanying Figure 4 The stacking part 10 comprises a carton temporary storage mechanism 11 arranged at the discharging port of the carton gluing and nailing device, a straightening mechanism 12 and a pushing mechanism 13 arranged at the feeding side of the carton temporary storage mechanism 11, a floating pressing mechanism 14 arranged above the carton temporary storage mechanism 11, a conveying mechanism 15 and a blocking mechanism 16 arranged at the discharging side of the carton temporary storage mechanism 11, the conveying surface of the carton temporary storage mechanism 11 is lower than the conveying surface of the conveying mechanism 15 so as to push the stacked and stacked cartons into the conveying mechanism 15, and the conveying surface of the carton temporary storage mechanism 11 is higher than the conveying surface of the carton gluing and nailing device so as to stack the cartons from bottom to top, thereby facilitating counting and stacking; the blocking mechanism 6 is used to block the conveying channel between the carton temporary storage mechanism 11 and the conveying mechanism 15, so as to store the stacked cartons to be packed on the carton temporary storage mechanism 11; the straightening mechanism 12 is used to straighten the side edges of the stacked cartons to be packed on the carton temporary storage mechanism 11; the pushing mechanism 13 is used to push the stacked cartons to be packed on the carton temporary storage mechanism 11 to the conveying mechanism 15 when the number of the stacked cartons reaches a preset number; the blocking mechanism 16 is also used to open the conveying channel between the carton temporary storage mechanism 11 and the conveying mechanism 15 when the pushing mechanism 13 works; the floating pressing mechanism 14 is used to apply a certain pressure to the cartons to be packed; and the conveying mechanism 15 is used to convey the stacked cartons to be packed to the collating part 20.

[0034] The straightening mechanism 12 comprises a straightening motor 121 and a straightening rotating shaft 122 connected with the output shaft of the straightening motor 121, a plurality of connecting pieces 123 are arranged side by side on the straightening rotating shaft 122, and a vertical straightening plate 124 is connected to the lower end of each connecting piece 123.

[0035] In this example, the straightening motor 121 is a cam motor, which drives the straightening rotating shaft 122 to rotate by a certain angle according to the rotation regularity of the straightening motor 121, so that the straightening plate 124 driven by the connecting piece 123 can straighten the side of the stacked cartons close to the carton gluing and nailing device, thereby making the carton packing and bundling effect better, more uniform and more firm, and ensuring the packing quality.

[0036] In this example, the pushing mechanism 13 includes a pushing fixing plate 131, two pushing cylinders 132 mounted on the pushing fixing plate 131, and two pushing connecting rods 133 vertically connected to the telescopic ends of the two pushing cylinders 132. A pushing mounting plate 134 is horizontally spanned between the two vertically arranged pushing connecting rods 133. A pushing lifting cylinder 135 is fixed on the pushing mounting plate 134. Pushing rods 136 are slidably sleeved on the lower part of each of the two pushing connecting rods 133. A pushing connecting plate 137 is horizontally spanned between the two pushing rods 136. The driving end of the pushing lifting cylinder 135 is fixedly connected to the pushing connecting plate 137 to drive the pushing rods 136 to move up and down. A stacking block 138 is connected to the lower end of the pushing rod 136. The pushing rod 136 is arranged between two adjacent aligning plates 124.

[0037] The working principle of the pushing mechanism 13 is as follows: When the stacked cartons reach a preset number, the pushing lifting cylinder 135 controls the pushing connecting plate 137 to drive the pushing rod 136 downward, so that there is only a certain gap between the stacking block 138 and the carton temporary storage mechanism 11. At this time, the pushing cylinder 132 extends a certain distance and, through the pushing connecting rod 133 and the pushing rod 136, inserts the stacking block 138 between the carton temporary storage mechanism 11 and the carton. Then, the pushing lifting cylinder 135 controls the pushing connecting plate 137 to drive the pushing rod 136 upward a certain distance, so that the subsequent cartons can be transported to the bottom of the stacking block 138 for stacking. Finally, the pushing cylinder 132 extends to drive the pushing connecting rod 133 to drive the pushing rod 136 to push the cartons above the stacking block 138 into the conveying mechanism 15. Please refer to the appendix. Figure 4 As can be seen, the aforementioned pushing mechanism 13 can realize the stacking and pushing of cartons, thereby effectively solving the technical problems of high labor intensity and low efficiency in manual stacking in the prior art.

[0038] In order to make the alignment mechanism 12 and the pushing mechanism 13 occupy less space and make it easier for them to cooperate to achieve the alignment and pushing of the carton, the pushing rod 136 is arranged between two adjacent alignment plates 124.

[0039] like Figure 2 As shown, the floating pressing mechanism 14 includes a support member 141 and a floating rod 142 independently installed at the end of the support member 141, and a pressing roller 43 is provided at the lower end of the floating rod 142.

[0040] The aforementioned floating pressing mechanism 14 uses the weight of the floating rod 142 and the pressing roller 143 to press the stacked cartons to a certain extent, so as to prevent the stacked cartons from falling apart and thus preventing normal stacking and subsequent packaging.

[0041] from Figure 2As shown, the blocking mechanism 16 comprises a blocking cylinder 161 and a blocking plate 162, the mounting end of the blocking cylinder 161 is hinged to the conveying mechanism 15, the driving end of the blocking cylinder 161 is hinged to the middle part of the blocking plate 162, and the lower part of the blocking plate 162 is hinged to the conveying mechanism 15.

[0042] When the cartons need to be blocked to facilitate the stacking of the cartons, the telescopic rod of the blocking cylinder 161 is extended to push the blocking plate 162 to a vertical state, thereby blocking the conveying channel between the carton temporary storage mechanism 11 and the conveying mechanism 15, so as to store the cartons to be packed in the carton temporary storage mechanism 11 in a stacked manner, and cooperate with the alignment mechanism 2 to align the cartons; when the stacked cartons to be packed in the carton temporary storage mechanism 11 reach a preset number, and the pushing mechanism 13 needs to push the cartons after being stacked into the conveying mechanism 15, the telescopic rod of the blocking cylinder 161 is retracted to pull the blocking plate 162 to rotate by a certain angle, thereby opening the conveying channel between the carton temporary storage mechanism 11 and the conveying mechanism 15 through the blocking plate 162, to ensure that the pushing mechanism 13 can push the cartons after being stacked into the conveying mechanism 15, thereby realizing automatic stacking and conveying of the cartons after being stacked.

[0043] In the implementation process of the embodiment, the carton temporary storage mechanism 11, the alignment mechanism 12, the pushing mechanism 13, the floating pressing mechanism 14, the conveying mechanism 15 and the blocking mechanism 16 can be arranged on a machine body (not shown in the figure). In addition, a counter 17 is arranged at the discharge port of the carton gluing and nailing device 110, and a controller is arranged in the machine body. The counter 17, the carton temporary storage mechanism 11, the alignment mechanism 12, the pushing mechanism 13, the floating pressing mechanism 14, the conveying mechanism 15 and the blocking mechanism 16 are electrically connected to the controller (not shown in the figure).

[0044] The working principle of the stacking part 10 is as follows: after the cartons output by the carton gluing and nailing device, the blocking plate 162 is pushed to a vertical state by the blocking cylinder 161, thereby blocking the conveying channel between the carton temporary storage mechanism 11 and the conveying mechanism 15, so that the cartons are stacked and temporarily stored on the carton temporary storage mechanism 11 in a top-down manner. At the same time, the counter 17 counts the number of cartons output by the carton gluing and nailing device, and the controller controls the alignment motor 121 to rotate regularly to drive the alignment shaft 122 to rotate by a certain angle, thereby driving the alignment plate 124 to align the side of the stacked cartons close to the carton gluing and nailing device through the connecting piece 123; the floating pressing mechanism 14 presses the stacked cartons to a certain degree through the self-weight of the floating rod 142 and the pressing roller 143, so as to avoid the stacked cartons from being scattered;

[0045] When the stacked cartons reach the preset number, the controller controls the pushing lifting cylinder 135 to drive the pushing connecting plate 137 to move the pushing rod 136 downward, so that there is only a gap between the stacking block 138 and the paper box temporary storage mechanism 11, the controller controls the pushing cylinder 132 to extend a certain distance through the pushing connecting rod 133 and the pushing rod 136, so that the stacking block 138 is inserted between the paper box temporary storage mechanism 11 and the paper box, then the controller controls the pushing lifting cylinder 135 to drive the pushing connecting plate 137 to move the pushing rod 136 upward a certain distance, so that the subsequent paper box is conveyed to the lower side of the stacking block 138 for stacking; the controller controls the extension rod of the blocking cylinder 161 to retract to rotate the blocking plate 162 by a certain angle, so as to guide the paper box temporary storage mechanism 11 and the conveying mechanism 15 through the blocking plate 162. The material conveying channel between the conveying mechanism 15; finally, the controller controls the pushing cylinder 132 to extend to drive the pushing connecting rod 133 to move the pushing rod 136 to push the paper box above the stacking block 138 into the conveying mechanism 15 for conveying to the finishing part 20 to arrange the paper box neatly.

[0046] As shown in Figures 5-8 The finishing part 20 includes a conveying line 21 connected to the discharge port of the conveying mechanism 15, and a guide mechanism 23, a first extrusion mechanism 24, a second extrusion mechanism 25, a pressing mechanism 26 and a blocking mechanism 27 are sequentially arranged along the conveying direction of the conveying line 21. The guide mechanism 23 is arranged at the inlet side of the conveying line 21, a support beam 28 is arranged near the outlet side of the conveying line 21, the first extrusion mechanism 24 and the second extrusion mechanism 25 are symmetrically arranged in the support beam 28, the guide direction of the guide mechanism 23 is located between the first extrusion mechanism 24 and the second extrusion mechanism 25, the pressing mechanism 26 is arranged on the side wall of the support beam 28 near the outlet side of the conveying line 21, the blocking mechanism 27 is arranged at the outlet of the conveying line 21, and a turning column 22 for turning the to-be-packed paper box by 90° is arranged on the conveying line 21. The turning column 22 is arranged on the front side of the guide mechanism 23 along the conveying direction.

[0047] The guiding mechanism 23 is used to guide the paper boxes to be packed after being separated into stacks to the first extrusion mechanism 24 and the second extrusion mechanism 25, the blocking mechanism 27 is used to block the paper boxes to be packed after being separated into stacks, the first extrusion mechanism 24 and the second extrusion mechanism 25 are used to push the side edges of the paper boxes blocked at the packing position to extrude the side edges of the paper boxes flat, and the pressing mechanism 26 is used to press the paper boxes after being extruded flat to facilitate the automatic packing operation of the paper boxes, so that the technical problems of high labor intensity and low efficiency existing in the manual operation in the prior art are solved. Meanwhile, the separated paper boxes are turned through the turning column 22, so that the cutting edges of the paper boxes are the packing edges, and then the positions possibly damaged during packing are located at the invisible interior after being packed, so that the quality of the paper box products is effectively improved.

[0048] In the example, the guiding mechanism 23 comprises a guiding mounting plate 231, a guiding driving motor 232, a guiding rotating rod 233 and a guiding plate 234, the guiding mounting plate 231 is fixedly connected with the conveying line 21, the guiding driving motor 232 is fixed on the lower surface of the guiding mounting plate 231, the output shaft of the guiding driving motor 232 is connected with the guiding rotating rod 233 located above the guiding mounting plate 231, and the guiding rotating rod 233 is connected with the guiding plate 234 through a guiding fixing block 235.

[0049] The guiding plate 234 can guide the paper boxes to be packed after being turned by the turning column 22 to the first extrusion mechanism 24 and the second extrusion mechanism 25, so that the first extrusion mechanism 24 and the second extrusion mechanism 25 push the side edges of the paper boxes to extrude the side edges of the paper boxes flat. The driving motor 232 drives the guiding plate 234 to rotate by a certain angle through the guiding rotating rod 233, so that the direction of the guiding can be adjusted according to the size of different products, so as to guide the paper boxes to be packed to the center position of the first extrusion mechanism 24 and the second extrusion mechanism 25 as much as possible.

[0050] Preferably, the first extrusion mechanism 24 and the second extrusion mechanism 25 are consistent in structure, wherein the first extrusion mechanism 24 comprises an extrusion cylinder 241 arranged in the cavity 281 formed in the support door beam 28, the output shaft of the extrusion cylinder 241 is arranged inwardly, two extrusion connecting rods 243 are connected with the output shaft of the extrusion cylinder 241 through an extrusion connecting plate 242, and an extrusion plate 244 is connected below the extrusion connecting rods 243.

[0051] The two extrusion plates 244 are driven to move towards each other through the two extrusion cylinders 241, so as to push the side edges of the paper boxes to extrude the side edges of the paper boxes flat, so that the technical problems of high labor intensity and low efficiency existing in the manual operation in the prior art are effectively solved, and the effect of bundling the paper boxes is better, more neat and more firm.

[0052] From Figure 6 And Figure 7 It can also be seen from the above that the pressing mechanism 26 comprises a mounting seat 261, a pressing cylinder 262, a pressing guide rod 263 and a pressing plate 264, the mounting seat 261 is fixed on the support door beam 28, the pressing cylinder 262 is fixed above the mounting seat 261, the telescopic end of the pressing cylinder 262 is connected with the pressing plate 264 below the mounting seat 261, and a pressing guide rod 263 is further connected on each side of the pressing plate 264, and the upper part of the pressing guide rod 263 is sleeved in the mounting seat 261.

[0053] After the side edges of the cartons are pressed flat by the first pressing mechanism 24 and the second pressing mechanism 25, the pressing cylinder 262 drives the pressing plate 264 to move downward until the cartons to be packed are pressed and fixed, so that the bundling effect of the cartons is better, more orderly and more firm. After the packing is completed, the pressing cylinder 262 is controlled to drive upward movement and reset.

[0054] From Figure 6 And Figure 7 It can also be seen from the above that the blocking mechanism 27 comprises a blocking installation beam 271, a blocking lifting cylinder 272, a blocking lifting plate 273, a blocking lifting rod 274 and a blocking plate 275, the blocking installation beam 271 is fixed below the conveying surface of the conveying line 21, the lifting cylinder 272 is fixed on the lower surface of the blocking installation beam 271, the telescopic end of the blocking lifting cylinder 272 is connected with the blocking lifting plate 273 above the blocking installation beam 271, two blocking lifting rods 274 are fixed on the blocking lifting plate 273, and the blocking plate 275 is fixed on the upper ends of the two blocking lifting rods 274. The blocking plate 275 is below the conveying surface of the conveying line 21 in a natural state, and can be driven by the blocking lifting cylinder 272 to move above the conveying surface of the conveying line 21.

[0055] Based on the above structure of the blocking mechanism 27, when the cartons need to be arranged, the blocking lifting cylinder 272 can drive the blocking lifting plate 273 and the blocking plate 275 to move above the conveying surface of the conveying line 21 to block the cartons to be packed at the packing position, so that the side edges of the cartons are pressed flat by the first pressing mechanism 24 and the second pressing mechanism 25. After the packing is completed, the lifting cylinder 272 drives the lifting plate 273 and the blocking plate 275 to move below the conveying surface of the conveying line 21 for reset, so as to facilitate the automatic output of the packed cartons and realize automatic packing.

[0056] Preferably, two lifting guide rods 76 are arranged in the mounting beams 71 on the left and right sides of the lifting cylinder 72, and upper ends of the two lifting guide rods 76 are fixedly connected with the lower surface of the lifting plate 73. Through the arrangement of the lifting guide rods 76, the lifting process of the lifting plate 73 can be more stable.

[0057] Based on the above structure, the working principle of the finishing part 20 is as follows:

[0058] Firstly, the paper boxes in the stack are turned through the turning column 22, so that the cutting edge of the paper box is the packaging edge;

[0059] Then, the guide plate 234 can guide the paper boxes to be packed after the turning column 22 to the direction to the first extrusion mechanism 24 and the second extrusion mechanism 25;

[0062] After that, the control of the pressing cylinder 262 drives the pressing plate 264 to move downward until the paper boxes to be packed are pressed and fixed, and the packing part 30 packs the paper boxes that are pressed and fixed;

[0063] After the packing is completed, the blocking lifting cylinder 272 drives the blocking lifting plate 273 and the blocking plate 275 to reset, and the pressing cylinder 262 drives the pressing plate 264 to reset, so as to facilitate the automatic output of the packed paper boxes, and realize automatic packing.

[0064] In the embodiment, the packing part 30 adopts the existing packing device, and the application does not improve it, so it is not described here.

[0066] During production, the length of the telescopic assembly 42 is adjusted as required, and then the side without the blocking assembly 45 is arranged close to the discharge port of the bundling and packaging production line. After the cartons are bundled and packaged, the cartons will move a certain distance along the first conveying roller 43 and the second conveying rollers 44 due to inertia after being output by the bundling and packaging production line, and finally stopped by the blocking assembly 45 or friction, thereby prolonging the bundling and packaging production line, and the bundled and packaged cartons can be temporarily stored on the telescopic assembly 42. At this time, the cartons can be directly stacked at the end of the bundling and packaging production line, thereby effectively improving the stacking efficiency and solving the defects of high labor intensity and low safety factor in the prior art.

The two second support columns 412 on the front and rear sides are connected through a connecting rod 415 to enhance the structural strength of the support assembly 41.

[0068] The relative positions of the first support column 411 and the second support column 412 can be adjusted by adjusting the locking bolt 413, thereby realizing the adjustment of the height of the support assembly 41 to make it consistent with the height of the discharge port of the bundling and packaging production line, so that the feeding mechanism of this example can adapt to bundling and packaging production lines of different heights, greatly improving the adaptability.

[0069] In the example, the telescopic assembly 42 comprises two X telescopic frames 421 arranged on the front and back sides, and the two X telescopic frames 421 are connected through a pull rod 422. The second conveying roller 44 is arranged between the two X telescopic frames 421. A sleeve 416 is sleeved on the upper part of the second supporting column 412. A connecting block 414 is fixed on the inner side wall of the sleeve 416 and the top of the second supporting column 412. The four corners of the X telescopic frame 421 are rotationally connected with the connecting block 414.

[0070] Through the telescopic assembly 42, the length of the unloading mechanism can be adjusted according to the needs, so that the temporary storage amount of cartons of the unloading mechanism can be adjusted according to the production needs, which helps to adjust the matching between the production rhythm and the stacking rhythm of the bundling and packaging equipment.

[0071] As shown in Figure 10 The blocking assembly 45 comprises a blocking rotation rod 451, a blocking frame 452, and a blocking mounting rod 453. The blocking rotation rod 451 is fixed on the supporting assembly 41. The blocking frame 452 is in a U shape. The two ends of the blocking frame are rotationally connected with the blocking sleeve 454 and the blocking rotation rod 451. The blocking mounting rod 453 is fixed on the middle part of the blocking frame 452. The locking assembly 46 is arranged on the blocking mounting rod 453.

[0072] The blocking rotation rod 451 is connected between the front and back second supporting columns 412. During production, the blocking frame 452 can be rotated around the rotation rod 451 through the sleeve 454, and is connected with the first conveying roller 43 through the locking assembly 46, so as to fix the position of the blocking assembly 45. When not in production, the locking assembly 46 can be released, and the blocking assembly 45 can be turned over to the lower side of the first conveying roller 43, so as to reduce the occupied space and facilitate the transfer and storage.

[0073] In the example, the locking assembly 46 adopts a hook. The hook is rotationally connected with the blocking mounting rod 451. The first conveying roller 43 is provided with a locking notch 461 matched with the hook.

[0074] When the blocking frame 452 is rotated around the blocking rotation rod 451, the hook is hooked in the locking notch 461, so as to fix the relative position between the blocking frame 452 and the supporting assembly 41, so as to realize the blocking function.

[0075] From Figure 9 With Figure 10 It can also be seen that, in order to facilitate the transfer of the unloading mechanism, the universal wheel 47 with a brake is arranged at the lower end of the supporting assembly 41. Specifically, the universal wheel 47 is arranged at the bottom of the first supporting column 411.

[0076] Accordingly, the working principle of the unloading part 40 in this example is as follows: during packaging production, the length of the telescopic assembly 42 and the height of the supporting assembly are adjusted according to the needs, so that the height of the unloading mechanism matches the discharge opening of the bundling and packaging equipment, while ensuring the matching between the production rhythm of the bundling and packaging equipment and the stacking rhythm, then the side without the blocking assembly 45 is close to the discharge opening of the bundling and packaging production line, the cartons after bundling and packaging will move a certain distance along the first conveying roller 43 and the second conveying roller 44 due to inertia after being output by the bundling and packaging production line, and finally stopped by the blocking assembly 45, thereby prolonging the bundling and packaging production line, and the cartons after bundling and packaging can be temporarily stored on the telescopic assembly 42, at this time, the stacking can be directly performed at the end of the bundling and packaging production line, thereby effectively improving the stacking efficiency and solving the defects of high labor intensity and low safety factor in the prior art.

[0077] The working principle of the production line is as follows:

[0078] The production line is composed of a stacking part, an arranging part, a packaging part and an unloading part, wherein the stacking part and the arranging part can automatically complete the stacking, unstacking and arranging of cartons, and the packaging part can automatically complete the packaging of cartons, thereby adopting the technical means of automatic stacking, automatic unstacking and automatic arranging, realizing the arrangement and compression of cartons before packaging, realizing automatic packaging of cartons, effectively solving the technical problems of high labor intensity and low efficiency in the prior art, and making the carton bundling effect better, more orderly and more firm. At the same time, the unloading part is used to realize the unloading of the packaged cartons, and the bundling and packaging production line can be prolonged through the unloading part, realizing the temporary storage of carton products, thereby realizing the stacking at the end of the packaging production line, and helping to further improve the efficiency of packaging operation.

[0079] Finally, it should be noted that the above description is only a preferred embodiment of the present application, and those skilled in the art can make various similar representations under the inspiration of the present application without deviating from the purpose and claims of the present application, and such changes fall within the protection scope of the present application.
