Technical Field

[0001] The utility model relates to the technical field of cardboard processing devices, and more specifically, to a flattening device used for carton production. Background Art

[0002] Cartons are the most common and widely used packaging products, usually used as wrapping for goods or as the outer layer for protecting items. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc. As an indispensable part of modern logistics, cartons bear the important responsibilities of containing, protecting products, and being beautiful, and their physical performance indicators have become the most important basis for their quality evaluation.

[0003] When producing cartons, operators often use flattening equipment to flatten the cardboard as the raw material. In actual use, although the existing flattening equipment has a basic flattening function, the existing flattening equipment generally flattens the cardboard by moving the pressing plate up and down, and the pressing plate is usually fixed inside the flattening equipment. Since the size of the pressing plate cannot be changed, it is difficult for the flattening equipment to flatten cardboards of different sizes, which limits the use range of the flattening equipment, so it needs to be improved.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 6 As shown, the utility model provides a flattening device for carton production, comprising:

[0028] A processing bed 1, the left and right sides of the upper surface of the processing bed 1 are fixedly connected with support plates 2, and the upper surface of the support plate 2 is fixedly connected with a top plate 3;

[0029] A connecting frame 4, the upper surface of the connecting frame 4 is movably connected to the middle of the lower surface of the top plate 3, and the lower surface of the connecting frame 4 is movably connected to a hollow pressing plate 5;

[0030] A disassembly mechanism, which is arranged on the upper surface of the hollow pressing plate 5;

[0031] Among them, the disassembly mechanism includes a No. 1 pneumatic cylinder 6, which is fixedly installed on the left side of the upper surface of the hollow pressure plate 5. The right end of the No. 1 pneumatic cylinder 6 is fixedly connected with a hinge block 7, and the upper surface of the hinge block 7 is hinged with a connecting rod 8, and the other end of the connecting rod 8 is hinged with a moving block 9. There are two moving blocks 9. The outer ends of the two moving blocks 9 both penetrate the connecting frame 4 and extend to the outside of the connecting frame 4. The outer surfaces of the two moving blocks 9 are movably connected to the inner surface of the connecting frame 4. The hinge block 7 moves to the left to disengage the two moving blocks 9 from the inner surface of the connecting frame 4.

[0032] When the No. 1 pneumatic cylinder 6 is running, the hinge block 7 will start to move to the left, and the movement of the hinge block 7 will drive the connecting rod 8, so that the two connecting rods 8 will start to rotate with the upper surface of the hinge block 7 as the axis. At the same time, the other ends of the two connecting rods 8 will respectively drive the two moving blocks 9, so that the two moving blocks 9 will start to move towards each other, and finally the two moving blocks 9 will detach from the inner surface of the connecting frame 4.

[0033] The outer surfaces on both sides of the two moving blocks 9 are movably connected with the limit bars 10 located below the connecting rod 8 , and the lower surface of the limit bar 10 is fixedly connected to the upper surface of the hollow pressure plate 5 .

[0034] The design of the limiting strip 10 ensures the stability of the two moving blocks 9 during movement.

[0035] Among them, a driving motor 11 is fixedly installed in the middle of the upper surface of the hollow pressure plate 5, and a round shaft 12 is fixedly sleeved on the other end of the output shaft of the driving motor 11. The bottom end of the round shaft 12 passes through the hollow pressure plate 5 and extends to the interior of the hollow pressure plate 5. The outer surface of the round shaft 12 and the inner surface of the hollow pressure plate 5 are movably sleeved.

[0036] When the driving motor 11 is running, the circular shaft 12 will start to rotate.

[0037] The outer surface of the circular shaft 12 is fixedly sleeved with a gear 13 located inside the hollow pressure plate 5, and the outer surface of the gear 13 is meshingly connected with a toothed plate 14. There are two toothed plates 14, and the two toothed plates 14 have the same size.

[0038] The rotation of the gear 13 drives the two tooth plates 14 , so that the two tooth plates 14 start to move in opposite directions.

[0039] The outer surfaces of the left and right sides of the hollow pressure plate 5 are movably connected with push plates 15 . There are two push plates 15 , and the two push plates 15 are fixedly connected to the outer ends of the two tooth plates 14 , respectively.

[0040] The two push plates 15 will move respectively under the drive of the two tooth plates 14, and flatten the cardboard during the movement.

[0041] Among them, the outer surfaces of the two push plates 15 are fixedly connected to the limit rod 16, the other end of the limit rod 16 passes through the hollow pressure plate 5 and extends to the inside of the hollow pressure plate 5, and the outer surface of the limit rod 16 and the inner surface of the hollow pressure plate 5 are movably connected.

[0042] The design of the limiting rod 16 ensures the stability of the two push plates 15 when they move.

[0043] Among them, a No. 2 pneumatic cylinder 17 is fixedly installed on the upper surface of the top plate 3, and the bottom end of the No. 2 pneumatic cylinder 17 penetrates the top plate 3 and extends to the lower surface of the top plate 3 and is fixedly connected to the upper surface of the connecting frame 4.

[0044] When the No. 2 pneumatic cylinder 17 is in operation, the connecting frame 4 as a whole will start to move downward.

[0045] The working principle and use process of this utility model:

[0046] First, the operator places the cardboard under the hollow pressing plate 5, and then the operator starts the No. 2 pneumatic cylinder 17. As the No. 2 pneumatic cylinder 17 runs, the connecting frame 4 and the hollow pressing plate 5 as a whole will begin to move toward the cardboard. Finally, when the hollow pressing plate 5 and the pushing plate 15 press the cardboard, the operator starts the driving motor 11. As the driving motor 11 runs, the circular shaft 12 and the gear 13 will begin to rotate, which will cause the two tooth plates 14 to move in opposite directions along the inner surface of the hollow pressing plate 5 as a whole. In this process, the two pushing plates 15 will push the unflattened part of the cardboard flat, thereby completing the flattening operation of cardboards of different widths.

[0047] When the operator needs to replace the hollow pressure plate 5 as a whole, the operator starts the No. 1 pneumatic cylinder 6. As the No. 1 pneumatic cylinder 6 runs, the hinge block 7 starts to move to the left, and the movement of the hinge block 7 drives the connecting rod 8 and makes it start to rotate, while the other end of the connecting rod 8 drives the moving block 9, so that the two moving blocks 9 start to move toward each other under the limit of the limit bar 10. Finally, the two moving blocks 9 will break away from the contact with the inner surface of the connecting frame 4, which releases the fixation of the hollow pressure plate 5 as a whole. At this time, the operator can take down the hollow pressure plate 5 as a whole for replacement.
