Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, and particularly relates to a stacking and aligning device. Background Art

[0002] In the cardboard production and packaging industries, the stacking of cardboard is a crucial link, which is directly related to the quality of the final product and production efficiency. Traditionally, a partition system is often used in the cardboard stacking process to control the number of cardboard stacked on the conveyor belt. This system realizes the separation and stacking of cardboard through the lifting movement of the partition above the conveyor belt. When the preset stacking number is reached, the partition rises, enabling the stacked cardboard to continue moving forward along the conveyor belt, while the subsequent cardboard stays in place waiting for the next stacking.

[0003] However, the existing partition blocking cardboard stacking technology has obvious defects. Specifically, during the process of the partition blocking the cardboard from advancing, due to the continuous operation of the conveyor belt and the inertia of the cardboard, the front end of the cardboard often collides with the partition. Such collisions will not only cause physical damages such as scratches and indentations on the cardboard surface, but may also cause the cardboard to break or deform severely in serious cases, seriously affecting the overall usability and subsequent processing performance of the cardboard.

[0004] In addition, the collisions may also generate noise and vibration, having an adverse impact on the production environment and equipment. In the long run, frequent collisions will also accelerate the wear of the partition and the conveyor belt, increasing the equipment maintenance cost and production downtime.

[0039] A stacking and aligning device according to an embodiment of the present utility model will be described below with reference to the drawings.

[0040] Referring to Figures 1-5 , an embodiment of a stacking and aligning device is provided in the present utility model.

[0041] A stacking and aligning device according to an embodiment of the present utility model includes: a frame 1, on which a first conveyor belt 2 and a second conveyor belt 3 for conveying cardboard are provided; a third conveyor belt 4, arranged at the end of the second conveyor belt 3, and the height of the third conveyor belt 4 is lower than that of the second conveyor belt 3; a blocking assembly, including a bracket 13 arranged above the third conveyor belt 4, on which a baffle 17 that can lift perpendicular to the third conveyor belt 4 is provided, a clamping plate 15 that can slide horizontally along the third conveyor belt 4 is provided on the side wall of the bracket 13, and a driving member for driving the movement of the baffle 17 and the clamping plate 15 is further installed on the bracket 13, and a flexible airbag 19 is installed on the side of the baffle 17 facing the second conveyor belt 3.

[0042] Specifically, the cardboard is conveyed to the second conveyor belt 3 through the first conveyor belt 2, and then conveyed to the third conveyor belt 4 through the second conveyor belt 3. When stacking the cardboard is required, the baffle 17 is lowered so that the bottom end of the baffle 17 fits the top surface of the third conveyor belt 4, thereby blocking the cardboard conveyed on the third conveyor belt 4. Since there is a height difference between the third conveyor belt 4 and the second conveyor belt 3, the cardboard falling on the third conveyor belt 4 is stacked on the third conveyor belt 4. After the cardboard is stacked, the stacked cardboard is compacted once by the clamping plate 15. After compaction, the baffle 17 is lifted, and the third conveyor belt 4 conveys the stacked cardboard to the next processing step.

[0043] When the cardboard on the second conveyor belt 3 is conveyed to the third conveyor belt 4, a plurality of flexible airbags 19 provided on the baffle 17 can make the surface of the baffle 17 have a certain elastic buffering effect. The flexible airbags 19 reduce or eliminate the collision between the cardboard and the partition, reduce the damage caused by the collision to the cardboard, so as to improve the production quality of the cardboard, reduce the production cost and protect the production environment.

[0044] Referring to Figure 5 , in some embodiments of the present utility model, a plurality of flexible airbags 19 are equidistantly arranged along the width direction of the baffle 17, and the flexible airbags 19 are in a strip-shaped structure, and their bottom ends are flush with the bottom surface of the baffle 17.

The air intake end of the air outlet pipe 20 is connected to the flexible airbag 19, and the air outlet end of the air outlet pipe 20 extends to the front side of the flexible airbag 19.

[0047] Specifically, the air pump 18 can be used to deliver gas into the flexible airbag 19, thereby ensuring that the flexible airbag 19 is always in an inflated state. At the same time, the gas entering the flexible airbag 19 will be ejected from the air outlet pipe 20 and act on the front side of the flexible airbag 19, forming an air curtain on the front side of the flexible airbag 19. The air curtain can further absorb the energy generated when the cardboard collides with the flexible airbag 19, reducing the damage caused by the collision to the cardboard.

[0048] Refer to Figure 5 , in some embodiments of the present utility model, a pipe seat 21 is installed on the outer wall of each air outlet pipe 20, and the pipe seat 21 is fixedly connected to the side wall of the baffle 17.

[0049] Specifically, the pipe seat 21 can fix the position of the air outlet pipe 20, preventing the air outlet pipe 20 from shifting with the deformation of the flexible airbag 19 and improving the installation stability of the air outlet pipe 20.

[0050] Refer to Figure 3 and Figure 4 , in some embodiments of the present utility model, the driving member includes a first cylinder 14 and a second cylinder 16.

The second cylinder 16 is fixedly installed on the top of the bracket 13, and the telescopic end of the second cylinder 16 is fixedly connected to the baffle 17.

[0051] Specifically, the first cylinder 14 can push the clamping plate 15 to displace towards the third conveyor belt 4. By cooperating with two clamping plates 15, the cardboard stacked on the third conveyor belt 4 can be pressed tightly, preventing the stacked cardboard from having a left-right position deviation and improving the stacking stability.

[0052] Refer to Figure 1 , in some embodiments of the present utility model, it further includes a conveyor 7 arranged above the first conveyor belt 2 and a pressure roller 8 rotatably installed inside the conveyor 7. The pressure roller 8 is arranged in parallel with the first conveyor belt 2, and there is a gap for a single cardboard to pass through between the outer wall of the pressure roller 8 and the top surface of the first conveyor belt 2.

[0053] Specifically, by rotating the pressing roller 8, the cardboard conveyed on the first conveyor belt 2 can be spread out, thereby preventing adjacent cardboard from stacking together and affecting the stacking of cardboard.

[0054] Referring to Figure 1 , in some embodiments of the present utility model, a swing frame 5 is rotatably arranged on the top of the frame 1, and a plurality of pressing wheels 6 are rotatably installed on the swing frame 5.
