Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, specifically a strip box bonding device. Background Technology

[0002] The working principle of a cardboard box forming machine is mainly based on the coordinated operation of an automated mechanical structure and a program control system. The equipment rapidly processes flat cardboard into three-dimensional cardboard boxes through processes such as paper feeding, die-cutting, folding, gluing, and forming.

[0003] CN108353995A discloses a functional conveying device for cardboard box gluing, including a conveying worktable, a limiting frame fixed to the top of the conveying worktable, and a conveying component fixed inside the limiting frame. Through the arrangement and operation of a fixed base, an electric telescopic rod, a mounting plate, and a local roughening component, this conveying device can roughen the gluing area on the inner wall of the cardboard box before gluing, which can significantly improve the gluing effect. By increasing the surface roughness of the inner wall of the cardboard box, a micro-uneven structure is formed. After the glue cures, mechanical interlocking occurs, increasing the contact area, improving adhesion and bonding strength. At the same time, it reduces surface energy and reduces the influence of surface tension, allowing the glue to spread evenly, adapting to various glue types, dispersing stress under force, enhancing structural stability, and improving environmental resistance. In addition, the gluing of the inner wall after roughening can increase the contact area, improve adhesion stability, and prevent sagging due to glue accumulation.

[0004] Existing technologies often suffer from poor coordination between actuators, unsmooth action transitions, and difficulties in changing models and making adjustments. This is especially problematic during multi-station synchronous operations, which can easily lead to waiting, interference, or repetitive actions, affecting overall operational efficiency and stability. Therefore, this paper proposes a compact, coordinated, and highly efficient carton bonding machine to achieve efficient and stable automated production. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A carton laminating device includes a frame, with an infeed conveyor for transferring carton shells into the frame and an outfeed conveyor for transferring the formed carton bodies to the outside, characterized in that:

[0014] Two movable carriages are slidably positioned above the linear slide rail. The distance between the two movable carriages is such that one movable carriage is located in the middle of the arched frame while the other movable carriage is located in the middle of the box forming mechanism.

[0015] Two fixed frames are respectively set on the top of two movable carriages. Two side wing limiting crossbars and two side wing rollers are symmetrically set on the four corner fixing blocks at the top of the fixed frames. The two symmetrically set side wing limiting crossbars and two side wing rollers form a square space in the middle for forming the cardboard board.

[0016] Two push-box assemblies are respectively set in front of two fixed frames to push out the cardboard box that forms a square space between the two side wing limiting crossbars and the two side wing rollers;

[0017] Two support plates are fixedly installed on the top of the two side wing limiting crossbars on the top of the two fixed frames, and are used to support the bending of the cardboard box cover.

[0018] Furthermore, the push box assembly also includes a strip push rod and a propulsion structure. The propulsion structure is located on the front side of the top of the fixed frame. A long strip connecting plate is provided in front of the fixed frame and connected to the fixed frame for mounting the propulsion structure. The strip push rod is slidably disposed on the top of the propulsion structure, and one end of the strip push rod is connected to the output end of the propulsion structure. The two side wing limiting crossbars of the fixed blocks at the four corners of the fixed frame are spaced apart from the fixed frame and have push box holes that allow the strip push rod to extend and retract.

[0019] Furthermore, the box-retrieving mechanism includes a linear module, a telescopic structure, and a suction plate, wherein,

[0020] The linear module and the top of the arched frame are intersected. One end extends to the top of the feeding conveyor mechanism on the outside of the frame, and the other end extends to the top of one of the fixed frames on the top of the box conveyor mechanism. The telescopic structure is fixedly installed on the sliding plate at the bottom of the linear module. The suction cup is installed at the output end of the telescopic structure and is used to suction the paper box board to the bottom of the suction cup.

[0021] Furthermore, the suction box has several suction holes at the bottom and a hose connector for connecting to the air pump at the top, with the suction holes communicating with the hose connector.

[0022] Furthermore, the box forming mechanism includes a lifting structure, multiple stacked plates, four corner pillars, four cylinders, four limiting mechanisms, a pressure plate roller, a pad block limiting frame, and an electric push rod, wherein,

[0023] Four corner posts are connected to the four corners of multiple laminated plates via bearings, and the laminated plates are connected to the arched frame on the side closest to the arched frame.

[0024] The top of the first-level space has four cylinders on the top of the stacked plate and they are distributed on the four sides of the stacked plate in the first-level space. The output end of each cylinder is also provided with strips for pressing the cardboard.

[0025] The lifting structure is set below the bottommost layered plate through a square hole in the middle of multiple stacked plates and two limiting rods. The top and bottom ends of the two limiting rods are respectively set on the topmost layered plate and the worktable through bearings. The output end of the lifting structure is also equipped with a push plate, which is clearance-fitted with the square hole in the middle of multiple stacked plates.

[0026] The top second-level space also has four limiting mechanisms at the four corners of the stacked plate. The limiting mechanism consists of a cylinder and an L-shaped limiter, which is used to squeeze the four corners of the cardboard box to the center.

[0027] The pressure roller is located on top of the stacked board in the intermediate layer space. It is mainly used to prevent the cardboard from being squeezed into the intermediate layer space and causing friction damage to the box itself.

[0028] The pad block limiting frame is located at the bottom of the stacked plate in the middle layer space to limit the position of the cardboard board when it enters. The electric push rod is set on the side of the stacked plate in the top second layer space near the arched frame to push the cardboard board to the discharge slide.

[0029] Furthermore, a warning light is provided at one top corner of the frame to indicate the operating status of the equipment.

[0040] 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.

[0041] Please see Figure 1-5 In this embodiment, a strip box bonding device includes a frame 1. The front of the frame 1 is provided with an infeed conveyor 2 for conveying the box shell into the frame 1, and the left and right sides of the frame 1 are provided with an outfeed conveyor 3 for conveying the formed box body to the outside.

[0042] The frame 1, together with the feeding conveyor 2 and the discharging conveyor 3, form a fully automated process for automatic feeding, precise conveying, efficient forming and smooth discharging of paper boxes;

[0043] The frame 1 has a workbench 12 inside to support the operation of the internal mechanism. The entire machine body 1 has a support plate for the operation of the internal equipment and is fixedly connected to the inner wall of the frame 1. The frame 1 supports the stable operation of the equipment operating mechanism. The top of the workbench 12 has an arched frame 7 in the middle. The top of the workbench 12 and near the back of the frame 1 have a box conveying mechanism 6 for conveying paperboards to the two sides for processing. The paperboards are quickly conveyed to the box forming mechanisms 8 on both sides of the arched frame 7 to be processed. The top of the arched frame 7 has a box picking mechanism 4 for grabbing the paperboards from the feeding conveyor 2 onto the box conveying mechanism 6. The paperboards 10 are sucked from the top of the feeding conveyor 2 into the box conveying mechanism 6 to complete the paperboard picking operation. The arched frame 7 has a box forming mechanism 8 on both sides for folding the paperboards and pushing the folded boxes to two discharge conveying mechanisms 3 for transportation.

[0044] The frame 1 has discharge windows 5 on both sides near the conveyor belts of the two discharge transmission mechanisms 3. These windows are used for discharging the formed paper box. Each discharge window 5 is equipped with a discharge slide 9 to facilitate the tilting and sliding of the formed box onto the conveyor belts of the two discharge transmission mechanisms 3. The discharge slide 9 is tilted. The box forming mechanism 8 pushes the formed box onto the tilted discharge slide 9 via a push rod, and then it falls onto the discharge transmission mechanism 3 to complete the discharge operation.

[0045] A warning light 11 is provided at one corner of the top of the frame 1 to indicate the equipment operation status. The location of the equipment failure can be determined by the alarm color of the different warning lights 11, and the operator can be given timely operation instructions.

[0046] Specifically, after the cardboard board 10 is fed into the designated position directly in front of the frame 1 via the feeding conveyor 2, the box-picking mechanism 4 is activated, using suction cups to pick up the cardboard board and transfer it to the box body conveyor 6. The box body conveyor 6 then transports the cardboard board to the box forming mechanisms 8 on both sides of the arched frame 7. The forming mechanisms, through the cooperation of multi-layer stacked plates and cylinders, gradually complete the forming actions such as folding, positioning, and compacting of the cardboard box. After forming, the box is pushed to the discharge window 5 by the box-pushing assembly, slides down the discharge slide 9 to the discharge conveyor 3, and is finally output from the equipment. Throughout the process, the warning light 11 displays the equipment's operating status in real time, facilitating monitoring and intervention by operators. The entire system has a compact structure and smooth operation, achieving efficient and stable automated strip box bonding production.

[0047] In this embodiment, the box conveying mechanism 6 includes a servo motor 61, two movable slides 62, a linear slide rail 63, two box pushing assemblies 64, two side wing limiting crossbars 65, two side wing rollers 66, two support plates 67, and two fixed frames 68, wherein...

[0048] The linear slide rail 63 is fixedly installed on the top of the worktable 12 as the core guide component of the box transfer mechanism 6, and at least one servo motor 61 is set on both sides of the linear slide rail 63. At the same time, the output end of the servo motor 61 is connected to the transmission shaft on the linear slide rail 63. The rotation of the transmission shaft is precisely controlled by the servo system, thereby driving the movable carriage 62 installed on the slide rail to perform reciprocating linear motion along a predetermined path.

[0049] This structure enables precise switching and synchronous control of workstations, ensuring that cardboard boards can be transferred stably and efficiently between the material handling station and the forming station during processing, thereby improving the coordination and positioning accuracy of equipment operation.

[0050] Two movable carriages 62 are slidably positioned above the linear slide rail 63. The distance between the two movable carriages 62 is such that one movable carriage 62 is located in the middle of the arched frame 7, while the other movable carriage 62 is located in the middle of the box forming mechanism 8.

[0051] This layout enables alternating operation of two workstations. While one moving carriage 62 receives the cardboard board 10 at the box-picking station, the other moving carriage 62 can simultaneously perform box forming operations at the forming station. Both are driven by a servo motor 61, moving synchronously and alternating on a linear guide rail 63, thus avoiding waiting time between processes and significantly improving the continuous operation efficiency and production cycle time of the equipment. Overall, this structure ensures smooth connection between the feeding and forming processes, demonstrating the equipment's excellent interconnectivity and efficiency.

[0052] Two fixed frames 68 are respectively set on the top of two movable slides 62. Two side wing limiting crossbars 65 and two side wing rollers 66 are symmetrically set on the four corner fixing blocks on the top of the fixed frame 68. The two side wing limiting crossbars 65 and two side wing rollers 66 are symmetrically set in pairs to form a square space for forming the cardboard board.

[0053] Two symmetrical side wing limiting crossbars 65 and two side wing rollers 66 are arranged to provide precise forming boundaries for the carton plate 10 placed inside, ensuring accurate positioning and no deviation of the carton during transportation and folding. Simultaneously, the side wing limiting crossbars 65 primarily serve a limiting function, preventing lateral movement of the carton plate; the side wing rollers 66 provide rolling contact when the carton plate enters or is adjusted, reducing frictional resistance and assisting in the smooth bending and forming of the carton's wings and other parts. The square space constitutes a movable, positioning, and guiding miniature forming mold space, ensuring the stability of the carton plate during dynamic transportation and preparing it for subsequent folding and forming processes.

[0054] Two push box assemblies 64 are respectively set on two fixed frames 68 to push out the paper box that forms a square space between the two side wing limiting crossbars 65 and the two side wing rollers 66. This ensures that the pushed paper box can enter the box forming mechanism 8 of the next stage in a preset posture and direction, avoiding jamming or displacement and ensuring the stability of the production rhythm.

[0055] Two support plates 67 are respectively fixedly installed on the top of the two side wing limiting crossbars 65 on the top of the two fixed frames 68, and are used to support the bending of the carton board cover. When the carton board 10 is pressed down by the box-removing mechanism 4 and bent into the square space formed symmetrically by the carton board 10, the two side wing limiting crossbars 65 and the two side wing rollers 66, the support plate 67 acts as a reliable support surface to support the cover and ensure that it can bend smoothly along the predetermined trajectory, preventing deformation or uneven folding caused by suspension or uneven force.

[0056] The push box assembly 64 also includes a strip push rod 641 and a propulsion structure 642. The propulsion structure 642 is located on the front side of the top of the fixed frame 68. A long strip connecting plate is provided in front of the fixed frame 68 and connected to the fixed frame 68 to serve as a platform for installing the propulsion structure 642. The strip push rod 641 is slidably located on the top of the propulsion structure 642, and one end of the strip push rod 641 is connected to the output end of the propulsion structure 642. The two side wing limiting crossbars 65 located at the four corner fixing blocks of the fixed frame 68 are spaced apart from the fixed frame 68 and have push box holes that allow the strip push rod 641 to extend and retract.

[0057] Specifically, the propulsion structure 642 serves as a power source and is fixed to the mounting platform on the front side of the fixing frame 68. When it is activated, it pushes the connected strip push rod 641 to slide in a straight line. During the sliding process, the strip push rod 641 can be aligned with and pass through a preset push box hole. This push box hole is located in the gap between the side wing limiting crossbar 65 and the body of the fixing frame 68. When the propulsion structure 642 is activated, the strip push rod 641 extends horizontally, passes through this hole, and directly acts on the side of the formed cardboard box, pushing the initially folded cardboard box from the square space to the box forming mechanism 8 for the next processing step.

[0058] In this embodiment, the box-retrieving mechanism 4 includes a linear module 41, a telescopic structure 42, and a suction cup 43, wherein...

[0059] The linear module 41 is intersected with the top of the arched frame 7. One end extends to the top of the feed conveying mechanism 2 on the outside of the frame 1, and the other end extends to the top of one of the fixed frames 68 on the top of the box conveying mechanism 6. The telescopic structure 42 is fixedly installed on the sliding plate at the bottom of the linear module 41. The suction plate 43 is installed at the output end of the telescopic structure 42 and is used to adsorb the paper box board on the bottom of the suction plate 43.

[0060] The suction box 43 has several suction holes at the bottom and a hose connector at the top that connects to the air pump. The suction holes are connected to the hose connector.

[0061] Specifically, the linear module 41 drives the entire box-picking mechanism 4 to move precisely laterally between the feeding point and the unloading point. After reaching the target position, the telescopic structure 42 controls the vertical lifting and lowering of the suction plate 43. At the feeding point, the suction plate 43 lowers and holds the cardboard board; then it rises, moves laterally to the unloading point, and lowers again to release the cardboard board onto the fixed frame 68 of the box-transfer mechanism 6. Through the automated action of "adsorption, translation, and release," manual loading is replaced, achieving seamless connection of the cardboard board from the feeding transfer mechanism 2 to the processing station.

[0062] In this embodiment, the box forming mechanism 8 includes a lifting structure 81, multiple stacked plates 82, four corner posts 83, four cylinders 84, four limiting mechanisms 85, a pressure plate roller 86, a pad block limiting frame 87, and an electric push rod 88.

[0063] Four corner posts 83 pass through the four corners of multiple stacked plates 82 and are connected by bearings. The multiple stacked plates 82 are connected to the arch frame 7 on the side closest to the arch frame 7. The multiple stacked plates 82 are divided into multiple layers from top to bottom, and each stacked plate 82 has a square hole at the bottom.

[0064] Each stacked plate 82 has a square hole at its bottom, which is used to facilitate the push plate at the output end of the lifting structure 81 to push the paper box plate 10 conveyed by the box conveying mechanism 6 from the bottom square hole to the processing step on each stacked plate 82 for processing.

[0065] The square holes at the bottom of each laminate 82 provide the necessary passage for the up-and-down movement of actuators such as cylinder push rods, enabling them to act on different levels of cardboard 10 to complete actions such as pushing and compacting.

[0066] The top of the first-level space has four cylinders 84 on its top and distributed along the four sides of the first-level space. The output end of each cylinder is also provided with strips for pressing the cardboard.

[0067] Four cylinders (484) operate simultaneously from four directions, driving the strips to press the four side walls of the cardboard box inward, quickly folding it from a flat state and initially forming the box shape. The synchronous lateral pressure ensures that the cardboard box has regular folds and a square shape, avoiding skewing or bulging, and laying an accurate geometric foundation for the subsequent compaction and bonding processes.

[0068] The lifting structure 81 is set below the bottommost stacked plate 82 through the square holes opened in the middle of the multiple stacked plates 82 and two limiting rods. The top and bottom ends of the two limiting rods are respectively set on the topmost stacked plate 82 and the worktable 12 through bearings. The output end of the lifting structure 81 is also provided with a push plate, which is clearance-fitted with the square holes opened in the middle of the multiple stacked plates 82.

[0069] Two limiting rods form a stable guide frame, which, together with the bearing, ensures that the lifting structure 81 and the push plate always maintain vertical movement during the lifting process, preventing skewing and jamming.

[0070] The gap fit design between the push plate and the square holes of each layer allows it to pass smoothly through all the stacked plates 82, thereby lifting the paper boxes located at the bottom or middle layer upwards and gradually transferring them to higher-level workstations for subsequent processing, or finally pushing the formed paper boxes out from the top.

[0071] The top second-level stacked plate 82 also has four limiting mechanisms 85 at its four corners. Each limiting mechanism 85 consists of a cylinder and an L-shaped limiter, used to squeeze and center the four corners of the cardboard box. After the cardboard box is initially erected, its corners may not be perfectly square or have slight deviations. The L-shaped limiter blocks squeeze from the corners, which can effectively correct the shape of the box and ensure that it is a regular rectangle, providing geometric assurance for subsequent bonding or sealing.

[0072] The pressure roller 86 is located on top of the stacked plate 82 in the intermediate layer space. It is mainly used to prevent the carton board that is squeezed into the intermediate layer space from being damaged by friction when it enters.

[0073] When the cardboard board is squeezed into the relatively narrow intermediate layer space, scratches are easily generated if its surface makes hard sliding contact with the top edge of the laminate 82. The pressure roller 86 can roll freely, allowing the cardboard board to make rolling contact with it when entering, which greatly reduces frictional resistance and the risk of surface damage.

[0074] The pad block limiting frame 87 is located at the bottom of the stacking plate 82 in the middle layer space to limit the position of the cardboard board when it enters. The electric push rod 88 is set on the side of the stacking plate 82 in the top second layer space near the arched frame 7 to push the cardboard board to the discharge slide 9.

[0075] The electric push rod 88 is located on the side of the stacked plate 82 near the arched frame 7 in the second-level space at the top. Its core function is to push the final formed cardboard box horizontally from the forming station so that it falls into the discharge slide 9 to complete the automatic discharge.

[0076] The working principle of the above embodiments is as follows:

[0077] After the cardboard board 10 is conveyed to the picking station in front of the frame 1 via the feeding conveyor 2, the linear module 41 of the box picking mechanism 4 drives the telescopic structure 42 and the suction plate 43 to move above the picking point. The telescopic structure 42 descends, and the suction plate 43 rises after adsorbing the cardboard board by negative pressure. Then, it moves along the linear module 41 to the unloading station above the box conveyor 6, releasing the cardboard board into the square space of the fixed frame 68.

[0078] The box conveying mechanism 6 drives two moving carriages 62 to move alternately on the linear slide rail 63 via a servo motor 61, achieving synchronous operation at two stations: one station receives the cardboard board in the middle of the arched frame 7, while the other station performs the forming operation at the box forming mechanism 8. The cardboard board is positioned on the fixed frame 68 by the side wing limiting crossbar 65 and the side wing roller 66, and the support plate 67 assists in the sealing and bending. When the cardboard board is in place, the pushing structure 642 of the box pushing assembly 64 pushes the strip push rod 641 to push the cardboard box into the box forming mechanism 8.

[0079] The box forming mechanism 8 achieves step-by-step forming through a multi-layer stacked plate structure 82: the cardboard board is first lifted into different levels of space by the lifting structure 81, and the four sides are erected and the corners are positioned by the cylinder 84 and the limiting mechanism 85. The pressure plate roller 86 reduces friction, and the pad block limiting frame 87 ensures accurate positioning. The finally formed cardboard box is pushed to the discharge slide 9 by the electric push rod 88, and slides down the inclined slide to the discharge transmission mechanism 3 for output.

[0080] Throughout the process, warning lights 11 display the equipment's operating status in real time, facilitating monitoring and intervention by operators. The system features a compact structure and smooth operation, achieving efficient, stable, and automated strip box bonding production.
