Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, specifically to a flipping, sorting, and aligning mechanism for corrugated cardboard. Background Technology

[0002] The corrugated cardboard flipping, sorting, and aligning mechanism is a core auxiliary equipment in corrugated carton production lines (such as before printing, die-cutting, and gluing processes). Its main function is to solve problems such as stacking tilt, misalignment, and uneven edges of cardboard during transportation, ensuring the accuracy and efficiency of subsequent processes (such as positioning printing and precise die-cutting).

[0003] Chinese Patent No. CN222833696U discloses a cardboard conveying and flipping mechanism, including a device base plate, a supporting vertical plate fixedly connected to the top of the device base plate, a conveying mechanism on the top of the device base plate, and a flipping mechanism on the top of the device base plate. With the above structural configuration, the cardboard conveying and flipping mechanism can realize the lifting of the cardboard by the lifting plate, and flip the cardboard on the top of the input track to the top of the output track by the rotation of the connecting column. Although the device does not press on the surface of the cardboard during the entire flipping process, thus avoiding damage to the surface of the cardboard or the production of pressing marks, the device is prone to the problem of cardboard deviation caused by premature tilting during flipping. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a flipping, sorting and aligning mechanism for corrugated cardboard, so as to solve the technical problems of cardboard offset caused by premature tilting and inability to flip multiple layers of cardboard.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a corrugated cardboard flipping, sorting and aligning mechanism, comprising a frame, wherein a flipping component, a driving component for driving the flipping component and an aligning component are rotatably connected to the frame, and the driving component includes a rotating shaft; Multiple flipping components are fixedly connected to the side wall of the rotating shaft. The flipping components are symmetrically arranged along the center line of the rotating shaft. Each flipping component includes a base plate, a first rod, and a second rod. The base plate is fixedly connected to the rotating shaft and is a square plate. The first rod and the second rod are fixedly connected to the side wall of the base plate and are symmetrically arranged along the center line of the side wall of the base plate. Except for the side wall fixed to the rotating shaft, the other side walls of the base plate are fixedly connected to the first rod and the second rod. The clapping assembly includes a mounting frame, a slide rail, a second motor, a chain, and clapping plates. The mounting frame is fixedly connected to the frame body. A slide rail is symmetrically fixedly connected along the center line of the section of the mounting frame facing the rotating shaft. The clapping plates are slidably connected to the slide rail. The motor is fixedly connected to the frame body. A first toothed block and a second toothed block that cooperate with the chain are fixedly connected to the top of the two clapping plates, respectively. The first toothed block and the second toothed block are fixed to both sides of the chain, respectively.

[0006] By adopting the above technical solution, multiple flipping components symmetrically arranged along the centerline are fixed to the side wall of the rotating shaft. The flipping components adopt a square base plate, and first and second rods are fixed to the side walls of the base plate except for the side wall fixed to the rotating shaft. At the same time, the first and second rods are symmetrically arranged along the centerline of the side wall of the base plate. This structural design allows the flipping components to stably clamp the corrugated cardboard under the drive of the rotating shaft, ensuring that the cardboard will not shift or fall during the flipping process, effectively improving the reliability of the flipping action. The aligning component adopts a mounting bracket to fix the slide rail, and the aligning plate is slidably connected to the slide rail. The tops of the two aligning plates are fixed to both sides of the chain through the first tooth block and the second tooth block, respectively. The chain is driven by the second motor to drive the aligning plate. This method of synchronous drive of the two aligning plates allows the aligning plates to move towards or separate from the centerline accurately and synchronously on the slide rail, ensuring that the aligning action of the cardboard is uniform and powerful, and avoiding the cardboard tilting caused by unilateral aligning.

[0007] Furthermore, a feeding conveyor belt and a discharging conveyor belt are fixed on the frame. Both the feeding conveyor belt and the discharging conveyor belt are multi-row spaced conveyor belts. The drive shaft is located between the feeding conveyor belt and the discharging conveyor belt. The feeding conveyor belt and the discharging conveyor belt have intervals that facilitate the passage of the flipping component.

[0008] By adopting the above technical solution, the feeding conveyor belt and the discharging conveyor belt are fixed on the frame, and both are multi-row interval conveyor belts. The drive shaft is set between the two, and the conveyor belt is reserved with intervals to facilitate the passage of the flipping component. This design allows the flipping component to pass smoothly through the conveyor belt intervals during rotation, avoids interference between the flipping component and the conveyor belt, and ensures that the flipping action and the conveying action do not affect each other.

[0009] Furthermore, the motor is fixedly connected to the frame, the output end of the motor is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the frame.

[0010] By adopting the above technical solution, the stable rotation of the drive shaft is ensured.

[0011] Furthermore, the central axis of the rotating shaft is on the same straight line as the midpoint of the side wall of the base plate.

[0012] By adopting the above technical solution, the central axis of the rotating shaft and the midpoint of the side wall of the base plate are set on the same straight line, which can keep the flipping component balanced during rotation, avoid the shaking or jamming of the flipping component due to the shift of the center of gravity, and ensure that the cardboard is always in a stable clamping state during the flipping process.

[0013] Furthermore, the upper ends of the feed conveyor belt and the discharge conveyor belt are in the same plane.

[0014] By adopting the above technical solution, the upper ends of the feeding conveyor belt and the discharging conveyor belt are set in the same plane, which can keep the cardboard at the same horizontal height during the process of entering the flipping component from the feeding conveyor belt and then transferring from the flipping component to the discharging conveyor belt. This avoids the cardboard getting stuck, folded, or falling during the transfer process due to the height difference of the conveyor belt, and ensures the smoothness of cardboard conveying.

[0015] Furthermore, the sidewalls of the first rod, the second rod, and the base plate form clamping grooves for holding the cardboard.

[0016] By adopting the above technical solution, a clamping groove for holding the cardboard is formed by the first rod, the second rod and the side wall of the base plate. This allows the cardboard to be stably confined within the clamping groove during the flipping process, preventing the cardboard from sliding or detaching from the flipping assembly and ensuring the smooth completion of the flipping action.

[0017] Furthermore, a first sprocket is fixedly connected to the output end of the second motor, and a second sprocket is rotatably connected to the mounting bracket. The chain rotates in cooperation with the first sprocket and the second sprocket.

[0018] By adopting the above technical solution, the first sprocket is fixed at the output end of the second motor, and the second sprocket is rotatably connected on the mounting bracket, so that the chain rotates in coordination with the first and second sprockets. This sprocket transmission method can ensure the accuracy of power transmission, so that the speed of the second motor is stably converted into the speed of the chain, thereby driving the clapper to move accurately on the slide rail, avoiding unstable movement of the clapper due to transmission errors.

[0019] In summary, the present invention has the following main advantages: 1. This utility model forms a clamping groove by cooperating with the first rod, the second rod and the bottom plate to stably clamp the cardboard and prevent the cardboard from tilting prematurely during the flipping process, thus preventing the cardboard from shifting.

[0020] 2. This utility model achieves synchronous driving of the clapper through the cooperation of the clapper, the second motor, the first sprocket, the second sprocket, the chain, the first tooth block and the second tooth block. This allows the clapper to move precisely and synchronously toward or apart from the center line on the slide rail, ensuring that the clapping action on the cardboard is uniform and powerful, and avoiding cardboard tilting caused by unilateral clapping.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In this example: A mechanism for flipping, sorting, and aligning corrugated cardboard, such as Figure 1-5 As shown, it includes a frame 6, on which a flipping component, a driving component for driving the flipping component and a aligning component are rotatably connected. The driving component includes a rotating shaft 1. Multiple flipping components are fixedly connected to the side wall of the rotating shaft 1. The setting of multiple flipping components can realize the continuous flipping operation of the cardboard. The flipping components are symmetrically arranged along the center line of the rotating shaft 1. Two flipping components can realize the stable flipping of the cardboard. The flipping component includes a base plate 2, a first rod 3 and a second rod 4. The base plate 2 is fixedly connected to the rotating shaft 1. Two base plates 2 are fixedly connected to the rotating shaft 1. The two base plates 2 are symmetrically arranged along the midpoint of the rotating shaft 1. The base plate 2 is perpendicular to the rotating shaft 1. The base plate 2 is a square plate. The first rod 3 and the second rod 4 are fixedly connected to the side wall of the base plate 2. The first rod 3 and the second rod 4 are perpendicular to the base plate 2. The first rod 3 and the second rod 4 are symmetrically arranged along the center line of the side wall of the base plate 2. Except for the side wall fixed to the rotating shaft 1, the other side walls of the base plate 2 are fixedly connected to the first rod 3 and the second rod 4, so that the base plate 2 can support the cardboard at different rotation angles and can achieve continuous flipping without adjusting the direction of the base plate 2. The clapping assembly includes a mounting frame 7, a slide rail 8, a second motor 10, a chain 13, and clapping plates 9. The mounting frame 7 is fixedly connected to the frame 6, providing a mounting platform for the other components of the clapping assembly. A section of the mounting frame 7 facing the rotation axis 1 is symmetrically connected to the slide rail 8 along the centerline. The slide rail 8 provides sliding guidance for the clapping plates 9, ensuring the precise movement trajectory of the clapping plates 9. The clapping plates 9 are slidably connected to the slide rail 8. The motor 18 is fixedly connected to the frame 6 and is used to drive the clapping plates 9 to slide. The tops of the two clapping plates 9 are respectively fixedly connected to a first tooth block 14 and a second tooth block 15 that cooperate with the chain 13. The chain 13 serves as a power transmission component, connecting the motor 18 and the clapping plates 9. The chain 13 drives the first tooth block 14 and the second tooth block 15, thereby driving the sliding of the two clapping plates 9. The first tooth block 14 and the second tooth block 15 are respectively fixed to both sides of the chain 13. The transmission method of the first tooth block 14 and the second tooth block 15 in conjunction with the chain 13 can realize the synchronous reverse movement of the clapping plates 9. See Figure 1 , Figure 2 , Figure 3 , Figure 4 The frame 6 is fixed with a feeding conveyor belt 16 and a discharging conveyor belt 17. Both the feeding conveyor belt 16 and the discharging conveyor belt 17 are multi-row interval conveyor belts, allowing the flipping component to pass smoothly through the intervals of the conveyor belts during rotation. The drive shaft 1 is set between the feeding conveyor belt 16 and the discharging conveyor belt 17 to achieve a smooth connection from feeding to flipping to discharging of the cardboard. The feeding conveyor belt 16 and the discharging conveyor belt 17 have intervals that facilitate the passage of the flipping component, ensuring that the flipping action and the conveying action do not interfere with each other. See Figure 1 , Figure 2 The motor 18 is fixedly connected to the frame 6 to ensure stable output of the motor 18. The output end of the motor 18 is fixedly connected to the rotating shaft 1. The motor 18 and the rotating shaft 1 are fixed by a coupling. The rotating shaft 1 is rotatably connected to the frame 6 to ensure stable rotation of the rotating shaft 1. See Figure 3 The central axis of the rotating shaft 1 and the midpoint of the side wall of the base plate 2 are on the same straight line, which can keep the flipping component balanced during rotation and avoid shaking or jamming of the flipping component due to the shift of the center of gravity. See Figure 1 , Figure 2 The upper ends of the feeding conveyor belt 16 and the discharging conveyor belt 17 are in the same plane to avoid the cardboard getting stuck, folded or falling during the transfer process due to the height difference of the conveyor belts, and to ensure the smooth conveying of the cardboard. See Figure 1 , Figure 2 , Figure 3The first rod 3, the second rod 4 and the side wall of the base plate 2 form a clamping groove for holding the cardboard, which can stably restrict the cardboard within the clamping groove during the flipping process and prevent the cardboard from sliding or detaching from the flipping assembly. See Figure 1 , Figure 2 , Figure 3 , Figure 4 The output end of the second motor 10 is fixedly connected to the first sprocket 11, which facilitates driving the chain 13. The second sprocket 12 is rotatably connected to the mounting bracket 7. The first sprocket 11 and the second sprocket 12 cooperate to make the rotational speed of the second motor 10 stably converted into the movement speed of the chain 13. The chain 13 rotates in cooperation with the first sprocket 11 and the second sprocket 12. The implementation principle of this embodiment is as follows: Figure 2 As shown, firstly, the corrugated cardboard is conveyed to the clamping slot by the feeding conveyor belt 16 on the frame 6. Then, the motor 18 drives the rotating shaft 1 to rotate. When the clamping slot holding the corrugated cardboard is perpendicular to the horizontal plane, the second motor 10 drives the chain 13 to rotate. The chain 13 drives the first tooth block 14 and the second tooth block 15 to move. The first tooth block 14 and the second tooth block 15 drive the two clappers 9 to slide inward to align the corrugated cardboard. At the same time, the feeding conveyor belt 16 conveys the corrugated cardboard to the next clamping slot. After alignment, the rotating shaft 1 continues to rotate. When the corrugated cardboard contacts the feeding conveyor belt, the next clamping slot is perpendicular to the horizontal plane, and the second motor 10 starts the clappers 9 to align the corrugated cardboard. The feeding conveyor belt 16 continues to convey the corrugated cardboard to the clamping slot. The feeding conveyor belt carries the corrugated cardboard away from the first clamping slot, completing the cycle of flipping.
