Description

Technical Field

[0001] This utility model relates to the field of paperboard production technology, specifically to a stacking device for paperboard production. Background Technology

[0002] Paperboard production is a relatively complex process, which usually includes major steps such as raw material preparation, pulping, paperboard forming and processing. Paperboard forming and processing includes forming, drying, pressing, surface treatment, cutting and finishing. After forming and processing, the paperboard needs to be stacked using a stacking device to facilitate subsequent packaging, transportation and storage. In existing technologies, cardboard stacked using a stacking device is formed by conveying the cardboard to a conveyor table. Under the friction of the conveyor belt, the cardboard moves upwards on the stacking table until it is thrown out by the conveyor belt and falls onto the stacking table, thus achieving the purpose of stacking the cardboard.

[0003] In actual use, the cardboard thrown by the conveyor belt falls onto the stacking platform. As the stacking height of the cardboard gradually increases with the number of cardboards, the time the cardboard spends in the air is shortened, resulting in horizontal inertial displacement. This causes the cardboard to deviate from the preset stacking position. The higher the height, the greater the misalignment. Furthermore, the misalignment will cause the corners of the subsequent cardboards to become misaligned, forming a stepped stack. This will cause the cardboard stack to tip over due to instability. Therefore, a stacking device for cardboard production is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stacking device for cardboard production, which has the advantage of facilitating the automatic arrangement of cardboard stacks. It solves the problem that when cardboard thrown by the conveyor belt falls onto the stacking platform, the stacking height gradually increases with the number of cardboards, resulting in a shorter air travel time for the cardboard, causing horizontal inertial displacement and ultimately deviating from the preset stacking position. Moreover, the higher the height, the greater the misalignment, and the misalignment will cause subsequent cardboard corners to be misaligned, forming a stepped stack, which will cause the cardboard stack to tip over due to instability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stacking device for cardboard production, comprising a stacking device and a pallet frame, wherein the stacking device is provided with a neat structure for aligning cardboard. The neat structure includes an adjustment bracket installed on the stacking device. The adjustment bracket is provided with two leveling components for aligning the two sides of the cardboard, and the two leveling components are symmetrically distributed from left to right. Each of the two leveling components is provided with an alignment component for aligning the front side of the cardboard. The adjustment bracket is provided with a drive component for controlling the two leveling components to flip and abut against the two sides of the cardboard. The leveling component includes a connecting block slidably mounted on an adjusting bracket, and a sleeve is rotatably mounted on the bottom of the connecting block. A connecting plate and an adjusting plate are fixedly mounted on the sleeve, and the connecting plate and the adjusting plate are both located on the same plane. A leveling frame is fixedly mounted on the connecting plate. The alignment component includes an electric push rod fixedly mounted on a connecting plate, an alignment frame slidably mounted on the connecting plate, and the telescopic end of the electric push rod fixedly connected to the alignment frame.

[0006] Furthermore, the adjusting bracket includes a support platform fixedly connected to the stacking device, a threaded rod is rotatably mounted on the support platform, and a connecting block is threaded onto the threaded rod.

[0007] Furthermore, the driving component includes a linear driver mounted on the support platform, and both ends of the linear driver are fixedly connected to connectors, which are hinged to the adjustment plate on the same side.

[0008] Furthermore, a mounting plate is fixedly connected to the bottom of the linear actuator, and a guide groove is provided on the support platform, and the guide groove is slidably connected to the protrusion at the bottom of the mounting plate.

[0009] Furthermore, the two threads on the threaded rod are symmetrically distributed from left to right, and the two connecting blocks are symmetrically installed on the threads of the threaded rod.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This cardboard stacking device controls the flipping of two leveling components through a drive component, causing the connecting plate and leveling frame in the leveling component to move closer to the cardboard stack direction, thereby eliminating the lateral offset of the cardboard and avoiding scratching or deformation of the cardboard during the straightening process. Then, the alignment frame in the alignment component moves closer to the cardboard stack direction, thereby eliminating the longitudinal offset of the cardboard, thus solving the problem of misalignment when stacking cardboard and preventing the cardboard stack from tipping over due to an unstable center of gravity. 2. This stacking device for cardboard production controls the movement of two connecting blocks to opposite sides by rotating the threaded rod, thereby controlling the synchronous movement of two leveling components. This allows for adjustment of the distance between the two leveling components, thus adapting to cardboard of different widths and facilitating the correction of misalignment in stacks of cardboard of different sizes. 3. In this stacking device for cardboard production, the linear driver pushes the adjusting plate through the connectors at both ends. The adjusting plate rotates around the rotation axis of the sleeve, causing the two connecting plates and the leveling frame to flip synchronously, thereby ensuring the accuracy of misalignment correction. Moreover, the protrusion at the bottom of the mounting plate slides synchronously along the guide groove, ensuring that the linear driver moves only along the axial direction and does not shift left or right or forward or backward.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please refer to Figure 1-3 This embodiment provides a stacking device for paperboard production, including a stacking device 1 and a pallet rack 2. The stacking device 1 is provided with a neat structure 3 for aligning the paperboard.

[0015] Example 2: Please refer to Figure 1-3 Based on Embodiment 1, the neat structure 3 includes an adjustment bracket 31 installed on the stacking device 1. The adjustment bracket 31 is provided with two leveling components 32 for aligning the two sides of the cardboard, and the two leveling components 32 are symmetrically distributed from left to right. Each of the two leveling components 32 is provided with an alignment component 33 for aligning the front side of the cardboard. The adjustment bracket 31 is provided with a driving component 34 for controlling the two leveling components 32 to flip and abut against the two sides of the cardboard. The leveling component 32 includes a connecting block 321 slidably mounted on the adjusting bracket 31, and a sleeve 322 rotatably mounted on the bottom of the connecting block 321. A connecting plate 323 and an adjusting plate 325 are fixedly mounted on the sleeve 322, and the connecting plate 323 and the adjusting plate 325 are both located on the same plane. A leveling frame 324 is fixedly mounted on the connecting plate 323. The connecting plate 323 and the adjusting plate 325 in the leveling component 32 are designed to be coplanar, so as to ensure that the leveling frame 324 is always parallel to the side of the cardboard when flipping, and to avoid scratching the cardboard or causing the cardboard to deform during the straightening process. The alignment component 33 includes an electric push rod 331 fixedly mounted on a connecting plate 323, an alignment frame 332 slidably mounted on the connecting plate 323, and the telescopic end of the electric push rod 331 is fixedly connected to the alignment frame 332.

[0016] Using the above technical solution, after the cardboard is thrown out by the conveyor, it falls into the stacking area of ​​the pallet rack 2. When the cardboard stack is misaligned, the linear actuator 341 extends and pulls the adjusting plate 325 through the connector 342, causing the sleeve 322 to rotate around the connecting block 321. The leveling frame 324 flips with the connecting plate 323 and gradually comes into contact with both sides of the cardboard to correct the lateral displacement of the cardboard caused by inertia. The electric push rod 331 retracts and drives the alignment frame 332 to slide along the connecting plate 323. The alignment frame 332 moves closer to the cardboard stack to eliminate the longitudinal displacement of the cardboard and ensure that the corners of the cardboard are aligned with the cardboard stacked below. After the cardboard is stably placed on the stacking table, the linear actuator 341 and the electric push rod 331 reset, and the leveling frame 324 and the alignment frame 332 leave the cardboard to facilitate the stacking of the next cardboard.

[0017] Example 3: Please refer to Figure 1-3 Based on Embodiment 2, the adjusting bracket 31 includes a support platform 311 fixedly connected to the stacking device 1, a threaded rod 312 rotatably mounted on the support platform 311, and a connecting block 321 threadedly mounted on the threaded rod 312.

[0018] The driving component 34 includes a linear driver 341 mounted on the support platform 311. Both ends of the linear driver 341 are fixedly connected to connectors 342, and the connectors 342 are hinged to the adjustment plate 325 on the same side. The linear driver 341 pushes the adjustment plate 325 through the connectors 342 at both ends. The adjustment plate 325 rotates around the rotation axis of the sleeve 322, causing the connecting plate 323 and the leveling frame 324 to flip synchronously. The leveling frame 324 flips to fit against the side of the cardboard, aligning the falling cardboard laterally. After the cardboard lands stably on the stacking table, the linear driver 341 resets, causing the leveling frame 324 to leave the cardboard, preparing for the correction of the next cardboard.

[0019] In addition, a mounting plate 343 is fixedly connected to the bottom of the linear actuator 341. A guide groove 313 is provided on the support platform 311, and the guide groove 313 is slidably connected to the protrusion at the bottom of the mounting plate 343. When the linear actuator 341 extends or shortens, the protrusion at the bottom of the mounting plate 343 slides synchronously along the guide groove 313, ensuring that the linear actuator 341 moves only along the axial direction and does not shift left or right or forward or backward. This avoids the linear actuator 341 tilting due to uneven force, ensures that the force direction transmitted from the connector 342 to the adjustment plate 325 is stable, and thus ensures that the leveling component 32 flips at a precise angle.

[0020] It should be noted that the two threads on the threaded rod 312 are symmetrically distributed from left to right, and the two connecting blocks 321 are symmetrically installed on the threads of the threaded rod 312. When the operator rotates the threaded rod 312, since the two connecting blocks 321 are installed on the symmetrical threads, the two connecting blocks 321 move synchronously in opposite directions along the axis of the threaded rod 312 under the drive of the threads. The two connecting blocks 321 drive the leveling component 32 to move synchronously, always maintaining a symmetrical distribution with the midpoint of the threaded rod 312 as the center, ensuring that the leveling frame 324 is always aligned with the central axis of the stacking table, and ensuring that the leveling component 32 is always centered and aligned, avoiding the two leveling frames 324 from deviating from the center of the stacking table due to improper adjustment.

[0021] Using the above technical solution, rotating the threaded rod 312 of the adjusting bracket 31 causes the two connecting blocks 321 to move towards the center or away from the sides simultaneously due to the symmetrical threads of the two threads of the threaded rod 312, thereby driving the two leveling frames 324 to adjust the spacing to match the width of the cardboard.

[0022] The working principle of the above embodiments is as follows: In actual use, the stacking device for cardboard production rotates the threaded rod 312 of the adjusting bracket 31. Since the two threads of the threaded rod 312 are symmetrical, the two connecting blocks 321 will move closer to the center or further away from the sides in sync, thereby driving the two leveling frames 324 to adjust the spacing to match the width of the cardboard. After the cardboard is thrown out by the conveyor, it falls into the stacking area of ​​the pallet rack 2. When the cardboard stack is misaligned, the linear actuator 341 extends and pulls the adjusting plate 325 through the connector 342, so that the sleeve 322 rotates around the connecting block 321. The leveling frame 324 flips with the connecting plate 323 and gradually comes into contact with both sides of the cardboard to correct the lateral displacement of the cardboard caused by inertia. The electric push rod 331 retracts, causing the alignment frame 332 to slide along the connecting plate 323. The alignment frame 332 moves closer to the cardboard stack, eliminating the longitudinal offset of the cardboard and ensuring that the edges and corners of the cardboard are aligned with the cardboard stacked below. After the cardboard is stably placed on the stacking table, the linear driver 341 and the electric push rod 331 are reset, and the leveling frame 324 and the alignment frame 332 leave the cardboard to facilitate the stacking of the next cardboard.
