Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard processing equipment, specifically to a flipping device for corrugated cardboard processing. Background Technology

[0002] Corrugated cardboard is a multi-layered paperboard made of face paper, liner paper, core paper, and corrugated paper bonded together. Due to its lightweight, high strength, and low cost, it is widely used in the packaging industry. In the processing of corrugated cardboard, it is often necessary to flip the cardboard to perform subsequent processes such as double-sided printing, lamination, or inspection. Traditionally, the flipping operation is mainly done manually. Manual flipping is not only labor-intensive and inefficient, but also prone to damage or surface contamination of the cardboard due to improper operation. To save manpower, mechanized flipping devices are now commonly used to replace manual flipping operations.

[0003] Utility model patent CN212863316U discloses a corrugated cardboard flipping machine, including a work frame. A self-locking pulley is fixedly connected to the lower surface of the work frame, and a lighting lamp is fixedly connected to the top inside the work frame. A drive platform is fixedly connected inside the work frame, and vacuum pumps are fixedly connected to both sides of the lower surface of the drive platform. A first flipping plate is provided on the upper surface of the drive platform, and a second flipping plate is provided on the upper surface of the drive platform near the first flipping plate. A first drive motor is slidably connected to the upper surface of the drive platform near the rear side of the first flipping plate. This utility model relates to the field of corrugated paper processing technology. Both sets of flipping plates in this corrugated cardboard flipping machine can move under the drive of the drive platform, thus making it suitable for processing equipment with different trajectories, increasing its practicality. Both sets of flipping plates are equipped with components for easy movement. Furthermore, both sets of flipping plates are equipped with adsorption components inside, which can adsorb and fix the corrugated paper.

[0004] While the aforementioned technical solutions have their advantages, most simple mechanical flipping mechanisms still have some shortcomings in use. For example, using two flipping mechanisms that can fold each other to perform the folding operation, although it is possible to transfer the cardboard from one folded board to another by flipping it 180 degrees, is prone to offset and skewing during the flipping process, resulting in poor flipping effect and affecting the quality of subsequent processing. Therefore, we propose a flipping device for corrugated cardboard processing. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a corrugated cardboard flipping device, including a linear conveyor belt 1 and a transfer conveyor belt 10. A flipping assembly 2 for flipping the cardboard is disposed above the linear conveyor belt 1 and the transfer conveyor belt 10. The flipping assembly 2 includes a crossbeam plate 20, on which a first cylinder 21 is fixedly mounted. A vertical beam 23 is detachably mounted at the end of the telescopic shaft of the first cylinder 21. A servo motor 231 is fixedly mounted on the vertical beam 23. A connecting rod 232 is fixedly mounted at the end of the output shaft of the servo motor 231. An assembly plate 24 is fixedly mounted at the end of the connecting rod 232. Multiple first vacuum suction cups 241 are fixedly mounted at the bottom of the assembly plate 24. The first vacuum suction cups 241 are driven by a first pump body 242. An electric slide 26 is fixedly mounted on the bottom surface of the crossbeam plate 20. A second cylinder 26 is fixedly mounted on the slide of the electric slide 26. 1. A base plate 263 is detachably installed at the end of the telescopic shaft of the second cylinder 261. Multiple second vacuum suction cups 264 are fixedly installed at the bottom of the base plate 263. The second vacuum suction cups 264 are driven by the second pump body 27. The first vacuum suction cup 241 and the second vacuum suction cup 264 are provided with suction force by the first pump body 242 and the second pump body 27, respectively, which can firmly adhere to the corrugated cardboard and prevent deviation or skewing during the flipping process. The servo motor 231 drives the assembly plate 24 and the first vacuum suction cup 241 to rotate 180 degrees precisely, so as to realize the stable flipping of the cardboard and solve the problem of poor flipping effect of traditional flipping mechanisms. In addition, after flipping, the second vacuum suction cup 264 can be used to adhere the flipped cardboard. Then, in conjunction with the second cylinder 261 and the electric slide table 26, the cardboard can be transferred from the linear conveyor belt 1 to the transfer conveyor belt 10 to complete the flipping operation.

[0019] In this embodiment, a steel plate 211 is fixedly installed at the end of the telescopic shaft of the first cylinder 21, and a top plate 22 is fixedly installed at the top of the vertical beam 23. The top plate 22 is detachably installed on the bottom surface of the steel plate 211 by multiple fastening bolts, which facilitates the fixing, installation and disassembly of the vertical beam 23.

[0020] Specifically, the servo motor 231 drives the assembly plate 24 and the first vacuum suction cup 241 to rotate to perform the flipping operation of the cardboard, and the first cylinder 21 is used to drive the first vacuum suction cup 241 to move up and down.

[0021] like Figure 2 As shown, a first guide post 25 is fixedly installed on the top surface of the top plate 22, and a first guide sleeve 251 is fixedly installed on the bottom surface of the crossbeam plate 20. The first guide sleeve 251 is fitted onto the first guide post 25 and slidably connected to the first guide post 25 to provide guidance for the top plate 22, making the top plate 22 more stable and smooth when moving up and down.

[0022] like Figure 2 As shown, a rectangular plate 262 is fixedly installed at the end of the telescopic shaft of the second cylinder 261, and the base plate 263 is detachably installed on the bottom surface of the rectangular plate 262 by multiple fastening bolts, which facilitates fixing, installation and disassembly operations.

[0023] like Figure 2 As shown, the first pump body 242 is detachably mounted on the mounting plate 24, and the second pump body 27 is detachably mounted on the base plate 263, which facilitates the fixed installation of the first pump body 242 and the second pump body 27.

[0024] like Figure 2 As shown, a second guide post 28 is fixedly installed on the top surface of the base plate 263, and a second guide sleeve 281 is fixedly installed on the bottom surface of the slide of the electric slide table 26. The second guide sleeve 281 is fitted on the second guide post 28 and slidably connected to the second guide post 28, so that the base plate 263 moves more stably and smoothly when moving up and down.

[0025] It is worth noting that the first vacuum suction cup 241 is connected to the first pump body 242 via a pipe, and the second vacuum suction cup 264 is connected to the second pump body 27 via a pipe. The pipe arrangement is reasonable. At the same time, the cables of the first pump body 242 and the second pump body 27 are also reasonably arranged. Since the rotation angle of the servo motor 231 is less than 360 degrees, after the output shaft of the servo motor 231 rotates to the corresponding angle once, it will work again and drive its output shaft to rotate to the starting point. If the corresponding position of the output shaft of the servo motor 231 is predetermined as the starting point, after the output shaft of the servo motor 231 rotates 180 degrees, as the cardboard is transferred from the first vacuum suction cup 241 to the second vacuum suction cup 264, the output shaft of the servo motor 231 will rotate 180 degrees in the opposite direction to return to the starting point. This ensures that the pipe arrangement of each part is reasonable and will not be affected by the movement.

[0026] Finally, it should be noted that the components involved in this utility model, such as the first cylinder 21, servo motor 231, first pump body 242, electric slide 26, second cylinder 261, second pump body 27, corresponding control system, and external power supply, are all general standard parts or components known to those skilled in the art. Their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0027] When the corrugated cardboard flipping equipment of this utility model is in use, the linear conveyor belt 1 transports the corrugated cardboard to the underside of the flipping assembly 2. The first cylinder 21 extends and drives the vertical beam 23 to move down. The first pump body 242 starts and causes the first vacuum suction cup 241 to adsorb the cardboard. Then the first cylinder 21 retracts and resets, driving the cardboard to rise to the corresponding height. Then the servo motor 231 works, driving the connecting rod 232, the assembly plate 24 and the cardboard to rotate 180 degrees to complete the flipping. Next, the electric slide 26 drives the second cylinder 261 to move above the flipped cardboard. The second cylinder 261 extends, causing the second vacuum suction cup 264 to contact the top surface of the cardboard. The second pump body 27 starts to adsorb the cardboard, the first vacuum suction cup 241 is released, and the electric slide 26 drives the cardboard to move above the transfer conveyor belt 10. After the second cylinder 261 extends, the second vacuum suction cup 264 is released, and the cardboard falls onto the transfer conveyor belt 10. The servo motor 231 rotates 180 degrees in the opposite direction to reset, completing one flipping operation.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
