[0026] The utility model discloses a honeycomb paperboard stacking and forming device, comprising:

[0027] The conveyor belt group 1 includes a first conveyor belt structure 11 for conveying a bottom plate 6. A second conveyor belt structure 12 and a third conveyor belt structure 13 are provided on both sides of the discharge port of the first conveyor belt structure 11. The conveying directions of the second conveyor belt structure 12 and the third conveyor belt structure 13 are arranged relatively, and the conveying position of the second conveyor belt structure 12 is higher than the conveying position of the first conveyor belt structure 11, and is used to convey the paper core 7 and convey the paper core 7 to the discharge port close to the first conveyor belt structure 11. A glue coating roller 121 is provided on the second conveyor belt structure 12. A space for the paper core 7 to pass through is reserved between the glue coating roller 121 and the second conveyor belt structure 12, and the glue coating roller 121 is provided on the second conveyor belt structure 12. The stick 121 is in contact with the top of the paper core 7, and the glue-coating stick 121 is used to glue the top of the paper core 7. The conveying position of the third conveyor belt structure 13 is higher than the conveying position of the first conveyor belt structure 11 plus the height of the bottom plate 6 and the paper core 7. The third conveyor belt structure 13 is used to convey the top plate 8 and convey the top plate 8 to the discharge port close to the first conveyor belt structure 11. The first conveyor belt structure 11 is provided with a fourth conveyor belt structure 14 at the discharge port. The first conveyor belt structure 11, the second conveyor belt structure 12, the third conveyor belt structure 13 and the fourth conveyor belt structure 14 are distributed in a cross shape. The fourth conveyor belt structure 14 is used to convey the stacked honeycomb paperboard;

[0028] A plurality of limiting components 2, each limiting component 2 is equidistantly distributed at one end of the discharge port of the first conveyor belt structure 11. When the conveyor belt group 1 conveys the paper core 7, each limiting component 2 is used to limit the range of movement of the paper core 7 when stacking, and maintain the limiting position of the paper core 7 after the paper core 7 falls on the bottom plate 6, so that the paper core 7 can be accurately stacked on the bottom plate 6. The limiting component 2 is also provided with an adjusting member 27, and the adjusting member 27 includes a lead screw 271 screw-fittedly connected to each limiting component 2. The rotation of the lead screw 271 can drive each limiting component 2 to rise and fall synchronously. Each lead screw 271 rotates synchronously through a transmission assembly 28, wherein at least one lead screw 271 is provided with a first gear 272;

[0029] The transmission component 4 is arranged on the third conveyor belt structure 13, and the transmission component 4 includes a first rack 42 arranged on the third conveyor belt structure 13, and the first rack 42 is slidably arranged along the movement direction of the third conveyor belt structure 13, and the first rack 42 is meshed with the corresponding first gear 272. When the top plate 8 is conveying, the top plate 8 can push the first rack 42 to move, and the first rack 42 is meshed with the first gear 272, so that the lead screw 271 is rotated to adjust the height of each limiting component 2, so that there is enough space between the limiting component 2 and the third conveyor belt structure 13 for the top plate 8 to pass through, so that the top plate 8 is transported to the paper core 7.

[0030] The telescopic limiting plate 5 is arranged between the first conveyor belt structure 11 and the fourth conveyor belt structure 14 to prevent the bottom plate 6 from moving.

[0031] In the specific implementation, the staff places the bottom plate 6 coated with glue on the first conveyor belt structure 11 and raises the telescopic limiting plate 5 until the bottom plate 6 abuts against one side of the telescopic limiting plate 5, and then the paper core 7 moves with the second conveyor belt structure 12. During this process, the top of the paper core 7 contacts the glue coating roller 121 and is coated with glue. The paper core 7 is conveyed on the second conveyor belt structure 12 and passes through the corresponding limiting component 2 and is stacked on the bottom plate 6. During the stacking process of the paper core 7, the corresponding limiting component 2 limits the range of movement of the paper core 7 when it falls, so that the paper core 7 can be stacked on the bottom plate 6 more accurately. Then, the top plate 8 moves under the drive of the third conveyor belt structure 13. During the movement of the top plate 8, the height of each limiting component 2 is adjusted through the cooperation between the transmission component 4 and the adjusting component 27, so that there is enough space for the top plate 8 to be transported between the limiting component 2 and the third conveyor belt structure 13. The top plate 8 passes through the corresponding limiting component 2 and is stacked on the paper core 7. The glue on the top of the paper core 7 is attached to the bottom surface of the top plate 8 to complete the stacking of the honeycomb paperboard. At this time, the telescopic limiting plate 5 descends, and the honeycomb paperboard is transported from the first conveyor belt structure 11 to the fourth conveyor belt structure 14, and then transported to the next process.

[0032] The utility model forms a honeycomb paperboard by stacking the bottom plate 6, the paper core 7 and the top plate 8 in sequence through the conveyor belt group 1. During the stacking process, the limiting component 2 and the transmission component 4 cooperate with each other to improve the stacking accuracy of the paper core 7 and the top plate 8 on the bottom plate 6. Under the premise of ensuring the stacking accuracy, manual stacking operation is not required, thereby reducing the labor intensity of the staff.

[0033] It should be noted that a photosensitive sensor (not shown in the figure) may be provided on the telescopic limiting plate 5, and the photosensitive sensor detects the height of the honeycomb paperboard to determine whether the honeycomb paperboard is stacked and thus automatically rises and falls.

[0034] In one embodiment, the limiting component 2 includes a fixed rod 21 arranged at one end of the discharge port of the first conveyor belt structure 11, the above-mentioned lead screw 271 is rotatably arranged on the corresponding fixed rod 21, a positioning sleeve 25 is provided at the top of the lead screw 271, a connecting rod 26 is provided between the positioning sleeve 25 and the fixed rod 21, the connecting rod 26 is used to connect the positioning sleeve 25 and the fixed rod 21, a first L-plate 22 is provided on the positioning sleeve 25, and a second L-plate 23 is vertically slidably provided on a surface of the first L-plate 22 close to the first conveyor belt structure 11, a moving ring 24 is spirally fitted on the lead screw 271, the above-mentioned second L-plate 23 is arranged on the moving ring 24, and the first L-plate 22 provides a vertical sliding guide constraint for the second L-plate 23 to prevent the moving ring 24 from driving the second L-plate 23 to rotate with the lead screw 271 when the lead screw 271 rotates; when the lead screw 271 rotates, the moving ring 24 is used to drive the second L-plate 23 to move vertically back and forth on the corresponding first L-plate 22.

[0035] With this design, when the top plate 8 drives the lead screw 271 to rotate through the transmission component 4, the lead screw 271 drives the second L-plate 23 to move vertically back and forth on the first L-plate 22 through the movable ring 24, and the positioning sleeve 25 positions the first L-plate 22 without affecting the movement of the second L-plate 23, so that the second L-plate 23 can be moved alone to clear space for the top plate 8 to pass through without moving the limiting component 2 as a whole.

[0036] In one embodiment, the transmission assembly 28 includes a transmission wheel 281 arranged on each screw 271, and the transmission wheel 281 is arranged below the corresponding first gear 272. The two transmission wheels 281 along the movement direction of the third conveyor belt structure 13 are provided with a transmission belt 282 that cooperates with the corresponding two transmission wheels 281. When one of the transmission wheels 281 rotates, the transmission belt 282 drives the corresponding screw 271 to rotate through the other transmission wheel 281.

[0037] With such a design, when the lead screw 271 rotates, the transmission wheel 281 on the lead screw 271 drives another corresponding transmission wheel 281 to rotate through the transmission belt 282, thereby driving another lead screw 271 to rotate, thereby achieving synchronous movement of the corresponding two second L-plates 23.

[0038] In one embodiment, the conveyor belt group 1 is provided with a guide component 3, and the guide component 3 includes guide strips 31 arranged on both sides of each conveyor belt structure, and the corresponding guide strips 31 gradually narrow along the direction from the inlet to the outlet of the corresponding conveyor belt structure. When the conveyor belt structure is working, the guide strips 31 are used to guide the corresponding material to be stably transported along a predetermined direction to prevent the material from deviating from the conveying trajectory.

[0039] With this design, when each conveyor belt structure is working, the corresponding guide strip 31 gradually narrows the conveying space of the corresponding material on the corresponding conveyor belt structure, so that the material is kept in the correct position.

[0040] In one embodiment, the guide strips 31 disposed on both sides of the third conveyor belt structure 13 are provided with slots 131;

[0041] The transmission component 4 includes a swing rod 41 swingably set in the groove 131 of the guide strip 31 on the third conveyor belt structure 13, one end of the swing rod 41 extends to the center of the third conveyor belt structure 13, the other end of the swing rod 41 is fan-shaped and has teeth, and the fan-shaped end of the swing rod 41 takes the rotating joint of the swing rod 41 as the center of the circle; the above-mentioned first rack 42 is set on one side of the swing rod 41 with teeth, and the first rack 42 is meshed with the teeth on the swing rod 41, and a support plate 43 is set on one side of the third conveyor belt structure 13, and the first rack 42 is slidably set on the support plate 43. The top plate 8 abuts and pushes the swing rod 41 to rotate during the conveying process, and the teeth on the swing rod 41 are meshed with the corresponding first rack 42 and drive the corresponding second L plate 23 to rise and fall through the adjusting member 27. A reset component is also provided on the support plate 43 for resetting the first rack 42.

[0042] With this design, when the top plate 8 is conveying, the top plate 8 abuts against and pushes the swing rod 41, causing the swing rod 41 to rotate toward the discharge port of the first conveyor belt structure 11. At this time, the end of the swing rod 41 with teeth rotates in the direction away from the discharge port of the first conveyor belt structure 11, and drives the first rack 42 to slide in the direction away from the first conveyor belt structure 11. The first rack 42 engages with the first rack 42 when sliding, and drives the second L plate 23 to rise through the lead screw 271. At this time, a gap is left between the third conveyor belt structure 13 and the second L plate 23 for the top plate 8 to pass through. As the top plate 8 moves, the top plate 8 leaves the swing rod 41, the swing rod 41 loses its constraint and drives the first rack 42 to reset through the reset component. At this time, the second L plate 23 descends and abuts against the top end of the top plate 8. When the top plate 8 is completely conveyed to the top end of the paper core 7, the second L plate 23 loses its constraint and the first rack 42 resets.

[0043] It should be noted that the friction coefficient between the third conveyor belt structure 13 and the top plate 8 is greater than the friction coefficient between the top plate 8 and the swing rod 41, so that the top plate 8 can pass through the swing rod 41 smoothly during transportation.

[0044] In one embodiment, the reset component includes a guide sleeve 441 arranged at one end of the support plate 43 away from the limiting component 2, and the above-mentioned first rack 42 is slidably arranged in the guide sleeve 441, and an elastic unit 442 is also arranged between the guide sleeve 441 and the first rack 42. When the top plate 8 leaves the swing rod 41, the first rack 42 loses its constraint, and the elastic unit 442 drives the first rack 42 to reset.

[0045] With this design, when the top plate 8 drives the swing rod 41 to rotate, the swing rod 41 drives the corresponding first rack 42 to move toward the feeding port of the third conveyor belt structure 13, the elastic unit 442 is compressed, and the first rack 42 is received in the guide sleeve 441; when the top plate 8 leaves the swing rod 41, the swing rod 41 loses its constraint, the elastic unit 442 is reset and pushes the first rack 42 out of the guide sleeve 441, and the first rack 42 drives the swing rod 41 to reset.

[0046] Preferably, the elastic unit 442 can be a spring in the prior art.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
