Description
Technical Field
[0001] The utility model relates to the technical field of palletizing, in particular to a palletizing device for cardboard production. Background Art
[0002] Cardboard is formed by compounding and pressing base paper and noodle paper. After cutting, the compounded cardboard will form cardboards of different specifications and sizes, which are used to produce different products such as cartons. After cutting, these cardboards need to be neatly stacked to facilitate the next step of production.
[0003] A search revealed reference to publication (announcement) number CN212923808U, which states in its background technology that "cardboard is typically stacked and palletized manually. This method of palletizing is very time-consuming and labor-intensive, not only making the work inefficient but also prone to danger." Reference to publication (announcement) number CN216155138U, which states in its background technology that "currently, cardboard is typically palletized manually on pallets during production, and manual palletizing is very labor-intensive." Therefore, it is understood that the prior art relies primarily on manual palletizing, which carries disadvantages such as high labor intensity and danger. To address these issues, a palletizing device for cardboard production is proposed. Utility Model Content

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] Reference Figure 1-4 A palletizing device for cardboard production comprises a base 1, a mounting frame 2 is provided on the base 1, two lifting screws 3 are installed on the mounting frame 2, a lower motor 14 connected to one of the lifting screws 3 is provided on the base 1, a palletizing box 5 is provided above the base 1, both of the lifting screws 3 are threadedly sleeved with a lifting block 4 connected to the palletizing box 5, a fixed frame 10 is installed on the palletizing box 5, a reciprocating screw 12 is rotatably provided between the fixed frame 10 and the palletizing box 5, an upper motor 11 connected to the reciprocating screw 12 is provided on the fixed frame 10, and a pushing frame 13 in the palletizing box 5 is threadedly sleeved on the reciprocating screw 12.
[0027] The two lifting screw rods 3 are fixedly mounted with pulleys 15, which are connected by a connecting belt 16. With the help of the pulleys 15 and the connecting belt 16, the two lifting screw rods 3 can be rotated synchronously. In order to ensure synchronization, the above components can optionally have a synchronization effect.
[0028] The upper end surface of the stacking box 5 is provided with an opening 6, and the surface of the stacking box 5 corresponding to the lifting screw 3 is provided with a placement opening 7. The opening 6 is convenient for multiple cardboards to be placed in the stacking box 5. As shown in the figure, there are two placement openings 7, which are convenient for lifting a lifting plate for multiple cardboards to enter. After multiple cardboards are placed in the stacking box 5, the lifting plate can be removed.
[0029] The palletizing box 5 is provided with a discharge port 8 on a surface away from the fixed frame 10, and a discharge rack 9 is provided on a surface of the palletizing box 5 corresponding to the discharge port 8. The discharge port 8 facilitates the removal of a cardboard, which is then moved to the destination for palletizing via the discharge rack 9. The height of the discharge port 8 is also the same as the thickness of a cardboard.
[0030] The inner bottom wall of the discharging rack 9 is provided with an inclined surface, and the inner bottom wall of the discharging rack 9 is polished. The polishing process ensures smoothness, and the inclined setting makes it more convenient to discharge the cardboard.
[0031] The pusher 13 is T-shaped from a top view, and its height is the same as the discharge port 8. The pusher 13 slides through the outer wall of the palletizing box 5 and extends into the interior of the palletizing box 5. Therefore, it is self-limited and does not rotate with the reciprocating screw 12. A storage slot is also provided on the inner wall of the palletizing box 5 near the fixed frame 10, allowing the pusher 13 to partially enter and remain hidden, thereby ensuring that multiple cardboard pieces can be placed in the palletizing box 5 and contact the inner bottom wall of the palletizing box 5.
[0032] When the present invention is used, multiple cardboards are lifted with the help of a lifting plate (horizontal plate) and lowered from the opening 6. The lifting plate is lowered in the two placement openings 7, and multiple cardboards enter the stacking box 5. When the lifting plate drops to the lowest point of the placement opening 7, the lifting plate can be pulled out horizontally. At this time, multiple cardboards continue to drop until the lowest cardboard contacts the bottom wall of the stacking box 5. At this time, the lower motor 14 is started, and the pulley 15 and the connecting belt 16 can realize the synchronous rotation of the two lifting screws 3. At this time, the stacking box 5 will rise and move to a suitable height, and it can stop when the discharge rack 9 corresponds to the stacking area.
[0033] The upper motor 11 is then started, driving the reciprocating screw 12. As the reciprocating screw 12 rotates, the pusher 13 moves out of the storage slot on the inner wall of the palletizing box 5 and pushes the bottom cardboard to the discharge port 8. It slides down the discharge rack 9 for palletizing (this cardboard is the bottom cardboard in the palletizing area). The palletizing box 5 then rises slightly. The pusher 13 then resets and returns to the storage slot. The second cardboard from the bottom up in the palletizing box 5 falls until it contacts the inner bottom wall of the palletizing box 5. At this point, the pusher 13 moves again to complete the removal of this cardboard, which can be stacked above the previous cardboard.
[0034] Finally, repeat the above steps to complete the stacking of multiple cardboards.
[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
