Description
Technical Field
[0001] This application relates to the technical field of cardboard finishing, and in particular to a cardboard pre-packaging finishing apparatus. Background Technology
[0002] As the cornerstone of modern logistics and product packaging, cardboard boxes directly impact the operations of downstream industries through their production efficiency and forming quality. On automated packaging production lines, corrugated cardboard is typically stacked and transported between processing units (such as printing, slotting, and die-cutting) via a conveyor system, ultimately reaching the final packaging stations for folding, gluing, or bagging. Ensuring that each stack of cardboard maintains neat edges and a uniform shape before entering the final station is crucial for accurate box dimensions, good sealing, and smooth equipment operation.
[0003] The current method of stacking and transferring cardboard mostly uses manual sorting. Although it has a certain degree of flexibility, manual sorting not only consumes a lot of labor costs, but also makes it difficult to unify the force and precision of manual operation. This can easily lead to slight deviations in the sorted cardboard, which in turn can cause dimensional errors or poor sealing in subsequent packaging processes. Utility Model Content
[0004] The purpose of this application is to provide a pre-packaging sorting device for cardboard, which solves the problem that manual sorting not only consumes a lot of labor costs, but also makes it difficult to unify the force and precision of manual operation, which can easily lead to slight deviations in the sorted cardboard, thus causing dimensional errors or poor sealing in subsequent packaging processes.
[0005] The cardboard packaging pre-processing device provided in this application adopts the following technical solution: it includes a base plate, two support plates are fixedly connected to the upper surface of the base plate, a plurality of transmission rollers are rotatably connected between the two support plates, a support frame is fixedly connected to the upper surface of the base plate, a fixed plate is fixedly connected between the support frame and the support plates, a clamping cylinder is fixedly connected to the upper surface of the fixed plate, a clamping plate is fixedly connected to the piston rod of the clamping cylinder, a lifting cylinder is fixedly connected to the top inner wall of the support frame, a lifting plate is fixedly connected to the piston rod of the lifting cylinder, a plurality of fixed blocks are fixedly connected to the lower surface of the lifting plate, a pressure roller is rotatably connected to the inside of the fixed blocks, a blocking cylinder is fixedly connected to the upper surface of the base plate, and a baffle is fixedly connected to the piston rod of the blocking cylinder. By adopting the above technical solution, the blocking cylinder can raise the baffle to intercept the cardboard and prevent it from moving excessively. Subsequently, the two clamping cylinders can move the two clamping plates to clamp and calibrate the cardboard laterally, ensuring that the cardboard remains centered. Then, the lifting cylinder lowers the pressure roller through the lifting plate to limit the height of the cardboard longitudinally, effectively preventing the cardboard from tilting. This achieves all-round position limitation in three directions: lateral clamping, longitudinal limitation, and end interception. After the limitation is completed, the baffle, clamping plates, and pressure roller return to their original positions, and the transmission roller starts to rotate, thereby conveying the cardboard. This solves the problem that manual sorting not only consumes a lot of labor costs, but also makes it difficult to unify the force and precision of manual operation, which can easily lead to slight deviations in the sorted cardboard, thus causing dimensional errors or poor sealing in subsequent packaging processes.
[0006] Preferably, one of the support plates has a plurality of first transmission belts on its side, each first transmission belt having two first synchronous pulleys internally connected to it, and each of the first synchronous pulleys being fixedly connected to a plurality of transmission rollers. A second transmission belt is provided between two adjacent first transmission belts, each second transmission belt having two second synchronous pulleys internally connected to it, and each of the second synchronous pulleys being fixedly connected to a plurality of first synchronous pulleys. By adopting the above technical solution, the first synchronous pulley, the first transmission belt, the second synchronous pulley, and the second transmission belt work together to achieve synchronous rotation of all transmission rollers, avoiding cardboard conveying jams or deviations due to uneven transmission, and ensuring the stability of cardboard conveying.
[0007] Preferably, two third synchronous pulleys are rotatably connected to the side of one of the support plates, and a third transmission belt is connected between the two third synchronous pulleys. A motor is fixedly connected to the upper surface of the base plate, and the output shaft of the motor is fixedly connected to one of the third synchronous pulleys, while the other third synchronous pulley is fixedly connected to one of the transmission rollers. By adopting the above technical solution, the motor provides stable power to the transmission roller through the third synchronous pulley and the third transmission belt, ensuring that the speed of the transmission roller is stable and adaptable to different paperboard conveying needs.
[0008] Preferably, a first buffer pad is fixedly connected to the side of the clamping plate away from the clamping cylinder, and a first slide rod is fixedly connected to both ends of one side surface of the clamping plate. The first slide rod is located inside the support frame and is slidably connected to the support frame. By adopting the above technical solution, the first buffer pad on the clamping plate can avoid damage to the cardboard surface during clamping, and the first slide bar can limit the movement trajectory of the clamping plate and prevent the clamping plate from shifting and causing regularity deviation.
[0009] Preferably, a second sliding rod is fixedly connected to both ends of the upper surface of the lifting plate, and the second sliding rod is located inside the support frame and slidably connected to the support frame; By adopting the above technical solution, the second slide bar on the lifting plate can guide the lifting plate to rise and fall smoothly, avoid positional deviation when the pressure roller contacts the cardboard, ensure longitudinal limiting effect, and prevent the cardboard from warping.
[0010] Preferably, a second buffer pad is fixedly connected to one side surface of the baffle, a slide rail is fixedly connected to one side surface of the support plate, a slider is slidably connected to the outside of the slide rail, and the slider is fixedly connected to the baffle. By adopting the above technical solution, the second buffer pad on the baffle can reduce the impact force when the cardboard is intercepted, and the slider and the slide rail cooperate to ensure that the baffle rises and falls smoothly.
[0011] Preferably, two side plates are fixedly connected to the upper surface of the base plate, and a plurality of fixing rods are fixedly connected between the two side plates. A plurality of rollers are rotatably connected to the outer side of the fixing rods. By adopting the above technical solution, the side plate, the fixed rod and the roller form a front buffer structure, which can bear the cardboard conveyed from the outside. The rolling of the roller buffers the inertia of the cardboard, avoids damage when the cardboard initially contacts the device, and ensures a smooth conveying transition.
[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. This pre-packaging paperboard finishing device, through the arrangement of transmission rollers, clamping cylinders, clamping plates, lifting cylinders, lifting plates, pressure rollers, blocking cylinders, baffles, fixing rods, and rollers, allows the paperboard to move by inertia above the rollers after the external conveying device has transported it, where it is buffered by the rollers and transferred to the top of the transmission rollers. This prevents damage caused by impact when the paperboard initially contacts the device. At this time, the blocking cylinder raises the baffle to intercept the paperboard and prevent it from moving excessively. Subsequently, the two clamping cylinders move the two clamping plates to clamp and calibrate the paperboard laterally, ensuring that the paperboard remains centered. Then, the lifting cylinder lowers the pressure rollers via the lifting plate, which limits the height of the paperboard longitudinally, effectively preventing the paperboard from tilting and achieving lateral clamping and finishing. The device provides omnidirectional position control in three directions: longitudinal limiting, end interception, and longitudinal positioning. After the limiting is completed, the baffle, clamp, and pressure roller return to their original positions, and the drive roller begins to rotate, thereby conveying the cardboard. This solves the problem that manual sorting not only consumes a lot of manpower, but also makes it difficult to unify the force and precision of manual operation, which can easily lead to slight deviations in the sorted cardboard, resulting in dimensional errors or poor sealing in subsequent packaging processes. The first and second buffer pads prevent rigid contact between the device and the cardboard during clamping and interception, reducing scratches and crushing of the cardboard surface. The rolling contact between the pressure roller and the cardboard provides longitudinal limiting, which can significantly reduce friction damage compared to rigid pressure plates. The multiple protective designs work together to ensure the integrity and flatness of the cardboard surface and reduce production losses. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0016] Example 1: A pre-packaging finishing device for cardboard, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The system includes a base plate 1, with two support plates 2 fixedly connected to the upper surface of the base plate 1. Several transmission rollers 3 are rotatably connected between the two support plates 2. A support frame 11 is fixedly connected to the upper surface of the base plate 1. A fixing plate 12 is fixedly connected between the support frame 11 and the support plates 2. A clamping cylinder 13 is fixedly connected to the upper surface of the fixing plate 12. A clamping plate 14 is fixedly connected to the piston rod of the clamping cylinder 13. A lifting cylinder 17 is fixedly connected to the top inner wall of the support frame 11. A lifting plate 18 is fixedly connected to the piston rod of the lifting cylinder 17. Several fixing blocks 19 are fixedly connected to the lower surface of the lifting plate 18. A pressure roller 20 is rotatably connected inside the fixing blocks 19. A blocking cylinder 22 is fixedly connected to the upper surface of the base plate 1. A blocking cylinder 22 is fixedly connected to the piston rod of the blocking cylinder 22. Plate 23, one of the support plates 2 has several first transmission belts 5 on its side, each first transmission belt 5 internally connected to two first synchronous pulleys 4, and each first synchronous pulley 4 is fixedly connected to several transmission rollers 3. A second transmission belt 7 is provided between two adjacent first transmission belts 5, each second transmission belt 7 internally connected to two second synchronous pulleys 6, and each second synchronous pulley 6 is fixedly connected to several first synchronous pulleys 4. Two third synchronous pulleys 8 are rotatably connected to the side of one of the support plates 2, and a third transmission belt 9 is connected between the two third synchronous pulleys 8. A motor 10 is fixedly connected to the upper surface of the base plate 1, and the output shaft of the motor 10 is fixedly connected to one of the third synchronous pulleys 8, while the other third synchronous pulley 8 is fixed... One of the drive rollers 3 is connected. A first buffer pad 15 is fixedly connected to the side of the clamping plate 14 away from the clamping cylinder 13. A first slide rod 16 is fixedly connected to both ends of one side surface of the clamping plate 14. The first slide rod 16 is located inside the support frame 11 and is slidably connected to the support frame 11. A second slide rod 21 is fixedly connected to both ends of the upper surface of the lifting plate 18. The second slide rod 21 is located inside the support frame 11 and is slidably connected to the support frame 11. A second buffer pad 24 is fixedly connected to one side surface of the baffle 23. A slide rail 26 is fixedly connected to one side surface of the support plate 2. A slider 25 is slidably connected to the outside of the slide rail 26. The slider 25 is fixedly connected to the baffle 23. Two side plates 27 are fixedly connected to the upper surface of the base plate 1. The two side plates 27 are fixedly connected to each other. Several fixed rods 28 are connected, and several rollers 29 are rotatably connected to the outer side of the fixed rods 28. Through the arrangement of the transmission roller 3, clamping cylinder 13, clamping plate 14, lifting cylinder 17, lifting plate 18, pressure roller 20, blocking cylinder 22, baffle 23, fixed rods 28, and rollers 29, after the external conveying device conveys the cardboard, the cardboard can move to the top of the rollers 29 by inertia and be buffered by the rollers 29, so that the cardboard is transferred to the top of the transmission roller 3, avoiding damage caused by impact force when the cardboard initially contacts the device. At this time, the blocking cylinder 22 can raise the baffle 23 to intercept the cardboard and prevent it from moving excessively. Subsequently, the two clamping cylinders 13 can move the two clamping plates 14 to clamp and calibrate the cardboard laterally.To ensure the cardboard remains centered, the lifting cylinder 17 lowers the pressure roller 20 via the lifting plate 18, limiting the cardboard height longitudinally and effectively preventing it from warping. This achieves omnidirectional positional limitation in three directions: lateral clamping, longitudinal limitation, and end interception. After limiting, the baffle 23, clamping plate 14, and pressure roller 20 return to their original positions, and the transmission roller 3 begins to rotate, thus conveying the cardboard. This solves the problems of manual sorting, which not only consumes a lot of manpower but also suffers from inconsistent force and precision, leading to slight deviations in the sorted cardboard and subsequent dimensional errors or poor sealing in packaging processes. The first buffer pad 15 and the second buffer pad 24 prevent rigid contact between the device and the cardboard during clamping and interception, reducing scratches and corner crushing. The rolling contact between the pressure roller 20 and the cardboard provides longitudinal limitation, significantly reducing friction damage compared to a rigid pressure plate. This multi-layered protective design ensures the integrity and flatness of the cardboard surface, reducing production losses.
[0017] The implementation principle of this application embodiment is as follows: Before use, the base plate 1 is moved to the side of the external conveying device so that the cardboard conveyed by the external conveying device can move above the roller 29. During use, after the external conveying device conveys the cardboard, the cardboard moves above the roller 29 by inertia. The roller 29 provides a buffer transition for the cardboard by passive rolling. Subsequently, the cardboard is smoothly transferred to the top of the transmission roller 3. At this time, the blocking cylinder 22 is activated, and the piston rod of the blocking cylinder 22 pushes the baffle 23 to rise. When the baffle 23 rises, it moves on the slide rail 26 via the slider 25. The sliding mechanism ensures smooth lifting and lowering of the baffle 23. After the baffle 23 rises, the cardboard contacts the second buffer pad 24, thus intercepting the cardboard. Subsequently, the two clamping cylinders 13 are activated simultaneously, and the piston rods of the clamping cylinders 13 push the clamping plate 14 to move. When the clamping plate 14 moves, it slides inside the support frame 11 via the first slide rod 16, ensuring the stability of the clamping plate 14's movement trajectory. Then, the first buffer pad 15 on the side of the clamping plate 14 makes close contact with both sides of the cardboard, keeping the cardboard in a centered state through symmetrical clamping force. Subsequently, the lifting cylinder 17 is activated, and the lifting cylinder... The piston rod of cylinder 17 drives the lifting plate 18 to descend. The lifting plate 18 slides inside the support frame 11 via the second slide rods 21 at both ends of its upper surface, ensuring that the lifting plate 18 moves smoothly downward until the pressure roller 20 contacts the upper surface of the cardboard, thus longitudinally limiting the height of the cardboard. After the cardboard has been limited and aligned in the transverse, longitudinal, and end directions, the blocking cylinder 22 drives the baffle 23 to descend and reset, the clamping cylinder 13 drives the clamping plate 14 to retract and reset, and the lifting cylinder 17 drives the lifting plate 18 and pressure roller 20 to rise and reset. Subsequently, the motor 10 is started. The output shaft of 0 drives the third synchronous pulley 8, which is fixedly connected to it, to rotate. The third synchronous pulley 8 drives another third synchronous pulley 8 to rotate through the third transmission belt 9, thereby causing one of the transmission rollers 3 to rotate. The transmission roller 3 drives the first synchronous pulley 4 on the adjacent transmission roller 3 to rotate through the first synchronous pulley 4 and the first transmission belt 5, which are fixedly connected. At the same time, the second synchronous pulley 6 between the adjacent first transmission belts 5 realizes power transmission through the second transmission belt 7, ensuring that all transmission rollers 3 rotate synchronously, and finally smoothly conveying the straightened cardboard to the next process.
