Description

Technical Field

[0001] This utility model belongs to the field of palletizing technology, specifically a palletizing lifting machine. Background Technology

[0002] As the packaging industry develops towards large-scale and diversified operations, corrugated paper, as a green and environmentally friendly packaging material, has expanded its applications to cover multiple fields such as e-commerce logistics, food transportation, and industrial product packaging. Downstream market demand for corrugated paper continues to grow, while simultaneously placing more diverse requirements on its specifications (such as size and thickness)—from narrow-width corrugated paper for packaging small electronic products to wide-width corrugated paper for transporting large household appliances, the frequency of specification switching between different batches of corrugated paper has significantly increased.

[0003] However, in the corrugated paper production process, palletizing is a key process connecting the processing and warehousing and transportation stages. Its core requirement is to quickly stack the processed corrugated paper into neat and stable stacks to ensure efficient use of subsequent storage space and safety during transportation. Currently, the palletizing equipment commonly used in the industry is based on a "conveyor + stacking" architecture. The conveyor system transfers the corrugated paper to the stacking platform, and then a simple positioning structure is used to achieve neat stacking of the corrugated paper. However, when production batches are switched or the specifications (width, length) of the corrugated paper change, the machine needs to be stopped and the positioning structure needs to be manually disassembled, reinstalled, or mechanically adjusted. This is not only time-consuming, but also prone to positioning accuracy deviations due to human error, which seriously disrupts the continuity of the production process and makes it difficult to meet the rhythm requirements of multi-batch, small-volume corrugated paper production.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A palletizing lift includes a support frame on which a second conveyor assembly and a first conveyor assembly are respectively mounted. A first connecting seat is mounted on the top of the support frame, and an alignment unit is provided on the first connecting seat.

[0007] The alignment unit includes a first shaft seat and a second shaft seat arranged in parallel on a first connecting seat. A first rotating shaft is rotatably connected to the first shaft seat, and a first sprocket is provided on the first rotating shaft. A second rotating shaft is rotatably connected to the second shaft seat, and a second sprocket is provided on the second rotating shaft. A chain is provided between the first sprocket and the second sprocket.

[0008] The chain is connected to a connecting frame via a fixed block, and the connecting frame is equipped with a stop block located on the No. 1 conveyor assembly;

[0009] A servo motor is also provided on the outer wall of the No. 1 connecting seat, and the output end of the servo motor is connected to the No. 1 rotating shaft for transmission.

[0011] The shredded paper cleaning unit includes a height adjustment component, on which a roller is mounted and rotatably connected to a second connecting seat. A brush is inclinedly mounted on the roller and located above the first conveyor assembly.

[0012] As a further preferred embodiment of this technical solution: the connecting frame is also provided with an axle, and a pulley is rotatably connected to the axle, and the pulley is arranged in close contact with the inner bottom wall of the first connecting seat.

[0013] As a further preferred embodiment of this technical solution: the height adjustment component includes a first cylinder rotatably mounted on a second connecting seat, the output end of the first cylinder being rotatably connected to a protrusion, and the end of the protrusion away from the first cylinder being fixedly connected to a roller shaft.

[0014] As a further preferred embodiment of this technical solution: a lifting unit is also installed on the second connecting seat;

[0015] The lifting unit includes a second cylinder mounted on a second connecting seat. The output end of the second cylinder is equipped with a drive rod, and the drive rod is equipped with a lifting frame located below the first conveyor assembly for supporting the first conveyor assembly.

[0016] As a further preferred embodiment of this technical solution: a fourth connecting seat is fixedly connected to the first connecting seat, a third rotating shaft is rotatably connected to the fourth connecting seat, and a roller is provided on the third rotating shaft, located between the first conveyor assembly and the second conveyor assembly.

[0017] As a further preferred embodiment of this technical solution: the support frame is provided with a slide rail, and the drive rod is slidably mounted on the slide rail.

[0019] As a further preferred embodiment of this technical solution: a third connecting seat is provided on the end of the fourth connecting seat away from the first connecting seat, for installing the second conveyor assembly.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] In this invention, the rotation of the sprocket and chain can drive the connecting frame and the stop block to move smoothly in a direction parallel to the first connecting seat. The stop block is adjusted to align with the edge of the corrugated paper on the first conveyor assembly. The position of the stop block can be calibrated in real time according to the size of different specifications of corrugated paper, ensuring that the edges of the corrugated paper are always neatly aligned when it is conveyed sheet by sheet from the second conveyor assembly to the first conveyor assembly for stacking, thus avoiding the problem of stacking tilting and collapsing. At the same time, the pulley on the bottom axle of the connecting frame slides against the inner bottom wall of the first connecting seat, which reduces the pressure of the connecting frame on the chain, reduces movement resistance and noise, and ensures the stability of the stop block adjustment.

[0022] In addition, brushes remove paper scraps from the surface of corrugated paper, preventing scraps from getting stuck between stacking layers and causing loose stacking and a loose structure, thus improving the density of the corrugated paper stack. Furthermore, when the corrugated paper is conveyed from the No. 2 conveyor assembly to the No. 1 conveyor assembly, the roller angle can be adjusted by the No. 1 cylinder to make the base of the brush fit against the upper surface of the corrugated paper, thus avoiding the problem of insufficient force and incomplete cleaning of scraps due to the excessive flexibility of the bottom edge of the brush.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1-4 This application provides a palletizing lift, including a support frame 1. A second conveyor assembly 26 and a first conveyor assembly 23 are respectively installed on the support frame 1. Corrugated paper on the second conveyor assembly 26 is conveyed one by one to the first conveyor assembly 23 and stacked together. In addition, the first conveyor assembly 23 is preferably a double conveyor belt structure, which can widen the width of the corrugated paper to be carried. It should be noted that the second conveyor assembly 26 and the first conveyor assembly 23 are existing products and are only used for conveying corrugated paper. They will not be described in detail. A first connecting seat 2 is installed on the top of the support frame 1, and an alignment unit is provided on the first connecting seat 2.

[0030] The alignment unit includes a first shaft seat 3 and a second shaft seat 7 arranged in parallel on a first connecting seat 2. The first shaft seat 3 and the second shaft seat 7 are preferably installed on the outer wall of the first connecting seat 2 by bolts, but not limited to bolt fixing. A first rotating shaft 4 is rotatably connected to the first shaft seat 3, and a first sprocket 5 is provided on the first rotating shaft 4. A second rotating shaft 8 is rotatably connected to the second shaft seat 7, and a second sprocket 9 is provided on the second rotating shaft 8. A chain 6 is provided between the first sprocket 5 and the second sprocket 9.

[0031] The chain 6 is connected to the connecting frame 11 via the fixing block 10. The connecting frame 11 is provided with a stop block 12, which is located on the first conveyor assembly 23.

[0032] A servo motor is also provided on the outer wall of the first connecting seat 2, and the output end of the servo motor is connected to the first rotating shaft 4 for transmission.

[0033] Specifically, corrugated paper is conveyed sheet by sheet to conveyor assembly 23 via conveyor assembly 26. Before this, the drive mechanism can drive shaft 4 to rotate, which in turn drives sprocket 5 to rotate. Then, through the action of sprocket 9, chain 6 rotates between sprocket 5 and sprocket 9. Chain 6 drives connecting frame 11 to move in a direction parallel to connecting seat 2 via fixing block 10, adjusting stop block 12 to the edge of the corrugated paper that has fallen onto conveyor assembly 23. Thus, during the process of stacking corrugated paper on conveyor assembly 23, the stop block 12 ensures the neatness of the stack and prevents the stacked corrugated paper from tilting and collapsing.

[0034] Furthermore, a second connecting seat 19 is fixedly connected to the first connecting seat 2, and a shredded paper cleaning unit is installed on the second connecting seat 19.

[0035] The shredded paper cleaning unit includes a height adjustment component, on which a roller 17 is mounted and rotatably connected to a second connecting seat 19. A brush 18 is inclinedly arranged on the roller 17. It should be noted that the brush 18 is preferably made of silicone, which has good flexibility. Located above the first conveyor assembly 23, the brush 18 can remove shredded paper from the surface of the corrugated paper during the process of transporting the corrugated paper from the second conveyor assembly 26 to the first conveyor assembly 23, thereby avoiding the loose stacking and loose structure caused by shredded paper being trapped between the stacking layers, and improving the density of the corrugated paper stack.

[0036] Furthermore, the connecting frame 11 is also provided with a wheel axle 13, and a pulley 14 is rotatably connected to the wheel axle 13. The pulley 14 is arranged close to the inner bottom wall of the first connecting seat 2. By bearing the pulley 14 on the inner bottom wall of the first connecting seat 2, the pressure of the connecting frame 11 on the chain 6 can be reduced. The wheel axle 13 can rotate as the connecting frame 11 moves. The rotation of the wheel axle 13 reduces the resistance to the movement of the connecting frame 11 and avoids noise generated by friction.

[0037] Furthermore, the height adjustment assembly includes a first cylinder 15 rotatably mounted on the second connecting seat 19, the output end of the first cylinder 15 is rotatably connected to a protrusion 16, and the end of the protrusion 16 away from the first cylinder 15 is fixedly connected to the roller shaft 17.

[0038] Specifically, the first cylinder 15 drives the protrusion 16 to rotate, and the rotation of the protrusion 16 drives the roller 17 to rotate. The rotation of the roller 17 can adjust the tilt angle of the brush 18, that is, adjust the height of the brush 18, so that the position of the brush 18 near the root can fit with the surface of the corrugated cardboard, avoiding the problem that the bottom edge of the brush 18 is too flexible, resulting in insufficient force to sweep away paper scraps.

[0039] Furthermore, a lifting unit is also installed on the second connecting seat 19;

[0040] The lifting unit includes a second cylinder 21 mounted on a second connecting seat 19. The output end of the second cylinder 21 is equipped with a drive rod 22. The drive rod 22 is equipped with a lifting frame 20 located below the first conveyor assembly 23, which is used to support the first conveyor assembly 23. During the process of the second conveyor assembly 26 conveying corrugated paper from the first conveyor assembly 23 one sheet at a time, the corrugated paper on the first conveyor assembly 23 gradually rises. Therefore, the second cylinder 21 can drive the drive rod 22 to move downward, and the drive rod 22 drives the first conveyor assembly 23 on the lifting frame 20 to gradually move downward.

[0041] Furthermore, a fourth connecting seat 27 is fixedly connected to the first connecting seat 2, and a third rotating shaft is rotatably connected to the fourth connecting seat 27. A roller 28 is provided on the third rotating shaft, located between the first conveyor assembly 23 and the second conveyor assembly 26. During the process of conveying the corrugated paper from the second conveyor assembly 26 to the first conveyor assembly 23, the roller 28 can prevent the corrugated paper from being scratched.

[0042] Furthermore, the support frame 1 is provided with a slide rail 24, and the drive rod 22 is slidably disposed on the slide rail 24, serving as a guide.

[0043] Furthermore, the support frame 1 is also equipped with a fan 29, located on the side of the first conveyor assembly 23, which can blow away the debris on the surface of the corrugated paper after the brush 18 has not removed all the debris.

[0044] Furthermore, a third connecting seat 25 is provided on the end of the fourth connecting seat 27 away from the first connecting seat 2, for installing the second conveyor assembly 26.

[0045] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
