Description

Technical Field

[0001] This application relates to the field of packaging material processing, and in particular to an automatic edge-trimming device for cardboard boxes. Background Technology

[0002] In today's era, product packaging plays a vital role in protecting product safety and enhancing brand image. As consumers' demands for product quality and packaging aesthetics continue to rise, the packaging box manufacturing industry faces enormous challenges in improving production quality and efficiency.

[0003] In the packaging box manufacturing industry, rectangular full-sheet paper die-cutting process is commonly used. However, traditional cutting methods have many problems. Traditional cutting involves the cutting blade acting directly on the cardboard. Since the cardboard is subjected to a large impact and shearing force during the cutting process, especially for easily damaged materials such as corrugated cardboard, this instantaneous force can easily damage the internal fiber structure of the cardboard, thereby causing the risk of material tearing.

[0004] To address the aforementioned issues, existing methods involve using a scoring device to score the cardboard. This involves scoring a row of shallow, discontinuous small notches or a deeper fine line on the excess edge of the cardboard, placing it in a state of near breakage. This prepares the cardboard for the breakage point. Subsequently, employees tear along the scoring or line to finish the edge trimming. However, this manual edge trimming is time-consuming and labor-intensive, hindering large-scale packaging box production and resulting in low production efficiency. Summary of the Invention

[0005] To improve the production efficiency of packaging boxes, this application provides an automatic edge-trimming device for cardboard packaging boxes.

[0006] This application provides an automatic edge-trimming device for cardboard packaging boxes, which adopts the following technical solution: An automatic edge-trimming device for cardboard packaging boxes includes: The rack is equipped with a control console, which is used to control the operation of the equipment; Integration mechanism, used to integrate cardboard; The conveying mechanism, used to receive the integrated cardboard, includes a conveyor drive assembly and a flexible belt. The conveyor drive assembly is mounted on the frame and is used to drive the flexible belt to move. The conveyor drive assembly is electrically connected to the control console. The edge-cutting mechanism is located at the top of the flexible belt. It slides with the frame and is used to press the cardboard on the flexible belt to tear the cardboard at the serrations or fine lines.

[0007] By adopting the above technical solution, the cardboard to be processed is sent to the integration mechanism. The integration mechanism aligns and organizes stacked or scattered cardboard, ensuring neat edges and providing a unified benchmark for subsequent conveying and edge-cutting processes. The integrated cardboard is transferred to the flexible belt of the conveyor mechanism. The control console sends instructions to the conveyor drive assembly, which starts and drives the flexible belt to move at a preset speed and direction, smoothly conveying the cardboard to the working area below the edge-cutting mechanism. The control console controls the edge-cutting mechanism according to a preset program. The edge-cutting mechanism applies downward pressure to the cardboard on the flexible belt. Due to the elasticity of the flexible belt, during the pressing process, the cardboard is subjected to the pressure of the edge-cutting mechanism and the reverse support force of the flexible belt. The force is concentrated at the notch or fine line, causing the cardboard to tear along that position, completing the edge-cutting. This equipment achieves full automation of the cardboard edge-cutting process through continuous conveying of the conveyor mechanism and automated pressing and tearing of the edge-cutting mechanism, eliminating the need for manual intervention. This significantly increases the processing capacity per unit time, meeting the needs of large-scale packaging box production. At the same time, traditional direct cutting methods easily damage the cardboard fiber structure, while this equipment utilizes the "pre-fracture" of the notch or fine line. The basic principle is to achieve tearing through precise pressing of the edge-cutting mechanism. During the pressing process, the force is evenly applied to the etched area through the buffer of the flexible belt, reducing the damage of the instantaneous impact force to the non-etched area of ​​the cardboard and reducing the risk of uncontrolled tearing of the material (such as irregular edges or excessive fiber damage). This not only improves the low efficiency of manual edge-cutting but also reduces the damage to the material caused by traditional cutting, achieving efficient and high-quality automatic edge-cutting of cardboard.

[0008] Optionally, the frame is rotatably connected to a feed drive screw, the frame is equipped with a worktable, the top wall of the worktable is provided with a sliding groove, a sliding block is attached to the sliding groove, the sliding block is threadedly connected to the feed drive screw, the frame is connected to a feed drive component, and the output end of the feed drive component is connected to the feed drive screw.

[0009] By adopting the above technical solution, when the cardboard needs to be edge-trimmed, the scattered or stacked cardboard is placed on the worktable, with the sliding block on the side close to the integration mechanism. The feeding drive is activated, which drives the feeding transmission screw to rotate. The sliding block, which is threadedly connected to the feeding transmission screw, moves along the sliding groove of the worktable. The sliding groove guides the direction of the sliding block and provides clearance for pushing the cardboard, so that the sliding block smoothly pushes the cardboard into the integration mechanism, completing the cardboard feeding operation. At the same time, the automated pushing of the sliding block replaces manual operation, which not only reduces the labor intensity of workers, but also reduces human operation errors through the precision of mechanical transmission, ensuring the consistency of the feeding position of each batch of cardboard, and providing stable preconditions for subsequent conveying, edge-trimming and other processes.

[0010] Optionally, the integration mechanism includes a first integration component, a suction cup component, a sliding drive component, and a second integration component. The first integration component is slidably connected to the frame. The suction cup component is used to pick up the cardboard. The suction cup component slides with the frame. The sliding drive component is used to drive the suction cup component to slide to the top of the conveying mechanism. The second integration component is slidably connected to the frame. The integration direction of the second integration component is perpendicular to the integration direction of the first integration component.

[0011] By adopting the above technical solution, when the cardboard is sent to the integration mechanism, the first integration component slides along the frame, approaches the cardboard from a certain direction and applies a pushing force to align the stacked or scattered cardboard in that direction. After the first direction integration is completed, the suction cup component slides along the frame to the top of the cardboard and picks up a cardboard through negative pressure. The second integration component slides along the frame and pushes the cardboard from a direction perpendicular to the first integration component to ensure that the cardboard remains regular in two vertical directions in the plane, reducing the impact of skew in one direction on the subsequent edge-cutting accuracy. Subsequently, the sliding drive component is activated, driving the suction cup component to slide to the top of the conveyor mechanism and place the picked-up cardboard smoothly on the flexible belt of the conveyor mechanism. Through the automated operation of the mechanical components, the integration mechanism realizes the fully unmanned operation of the cardboard from alignment after being pushed to transfer to the conveyor mechanism. This not only reduces the intensity of manual labor but also reduces integration errors through the stability of mechanical transmission, improves the consistency of the regularity of each batch of cardboard, lays the foundation for the stable operation of subsequent processes, and reduces material waste and rework costs caused by improper integration.

[0012] Optionally, the first integrated component includes a first guide plate, a second guide plate, and a guide drive. The first guide plate is connected to the frame, the second guide plate is slidably connected to the frame, the guide drive is connected to the frame, and the output end of the guide drive is connected to the second guide plate. The guide drive is used to drive the second guide plate to move closer to or away from the first guide plate.

[0013] By adopting the above technical solution, when the sliding block pushes the cardboard to the integration mechanism area (between the first guide plate and the second guide plate), the guide drive is activated. The output end of the guide drive drives the second guide plate to slide along the frame towards the first guide plate. The second guide plate gradually approaches the edge of the cardboard and applies a smooth pushing force to the cardboard, so that the other edge of the cardboard is in contact with the fixed first guide plate until the cardboard is aligned in that direction. The first guide plate serves as a fixed reference, providing a clear alignment reference for the cardboard and avoiding the deviation caused by "no reference" in traditional manual integration. The second guide plate pushes the cardboard with controllable force and speed through the stable drive of the guide drive, ensuring that the edge of the cardboard is tightly in contact with the first guide plate. This effectively solves the problem of skewing of stacked or scattered cardboard in a single direction, reduces the possibility of unstable suction cup picking, misalignment of conveying, or deviation of falling edge due to cardboard offset, and improves the overall production continuity of the equipment.

[0014] Optionally, the second integrated component includes a connecting frame, a push plate, and a support member, wherein the connecting frame is slidably connected to the frame, the connecting frame is slidably connected to the push plate, and the support member is connected to the push plate.

[0015] By adopting the above technical solution, when the first integration component completes the one-way integration of the cardboard and the cardboard is in the position to be integrated in the second direction, the connecting frame moves toward the direction closer to the conveying mechanism, and the push plate is raised and lowered to support the bottom of the cardboard. One side of the push plate applies a horizontal pushing force to the side of the cardboard, so that the cardboard is aligned on one side in the direction perpendicular to the horizontal plane of the first integration direction, thus completing the two-way integration. The cardboard is neat in both vertical directions in the plane, reducing the problems of cardboard skewing and uneven edges, and providing a more accurate position reference for subsequent suction cup picking, conveying and edge finishing processes.

[0016] Optionally, the support includes a connecting part and a rotating part. The connecting part is connected to the push plate, and the rotating part is rotatably connected to the connecting part. In the vertical direction, the outer wall of the rotating part protrudes from the bottom wall of the connecting part.

[0017] By adopting the above technical solution, when the cardboard moves to the area of ​​the first integration component, the push plate is activated to descend, so that the rotating part is attached to the top wall of the cardboard stack. The rotating part limits the top direction of the cardboard. When the first integration component is integrated, the possibility of the cardboard warping is reduced, and the integration flatness of the cardboard is further improved.

[0018] Optionally, the suction assembly includes a movable base, a lifting drive, and a suction tray. The movable base slides with respect to the frame, the lifting drive is connected to the movable base, and the output end of the lifting drive is connected to the suction tray.

[0019] By adopting the above technical solution, after the first integration component completes the integration operation, the lifting drive is activated, and the lifting drive drives the suction plate to move, so that the suction plate picks up the cardboard. The suction plate adsorbs the cardboard through negative pressure, which reduces the squeezing of the cardboard edges compared with mechanical clamping, and can effectively reduce the possibility of cardboard wrinkles and deformation of thick cardboard.

[0020] Optionally, the sliding drive assembly includes a sliding drive component, a sliding transmission screw, and a sliding guide rod. The sliding drive component is connected to the frame, the output end of the sliding drive component is connected to the sliding transmission screw, the sliding transmission screw is rotatably connected to the frame, the suction cup assembly is threadedly connected to the sliding transmission screw, the sliding guide rod is connected to the frame, and the suction cup assembly is slidably connected to the sliding guide rod.

[0021] By adopting the above technical solution, when the suction cup assembly needs to be moved, the sliding drive receives the control signal and starts. The output end of the sliding drive drives the sliding transmission screw to rotate. The sliding connection between the suction cup assembly and the sliding guide rod restricts the tendency of the suction cup assembly to rotate with the sliding transmission screw. This allows the rotational motion of the sliding transmission screw to be converted into linear driving force through the threaded pair. When the cardboard is moved from the paper pick-up position to the top of the conveying mechanism, it can be accurately aligned with the center or baseline of the conveying surface, reducing the possibility of cardboard falling or subsequent integration process errors due to positional offset, and improving the overall positioning accuracy of the equipment.

[0022] Optionally, the conveying drive assembly includes a rotating drive component and a rotating roller. The rotating drive component is connected to the frame, and the rotating roller is rotatably connected to the frame. Multiple rotating rollers are provided. The output end of the rotating drive component is connected to one of the rotating rollers, and the flexible belt meshes with the rotating roller.

[0023] By adopting the above technical solution, when materials need to be conveyed, the rotary drive is activated, which drives the rotary roller connected to the output end of the rotary drive to rotate. Through meshing with the flexible belt, the flexible belt moves along the tangential direction of the rotary roller. At the same time, other rotary rollers rotate synchronously with the belt under the meshing action of the flexible belt, forming a cyclical motion of the entire conveying path. The rotary drive is directly connected to the drive roller, and the meshing transmission between the flexible belt and the rotary roller reduces the possibility of material accumulation or uneven spacing caused by speed fluctuations. At the same time, it reduces transmission failure caused by belt slack and improves the reliability of equipment operation.

[0024] Optionally, the flexible belt includes an engaging part, a flexible part, and a sliding part. The engaging part engages with the rotating roller and is symmetrically arranged on both sides of the conveying direction of the flexible part. The engaging part is connected to the sliding part, and the flexible part is coiled around the rotating roller and is in a tensioned state.

[0025] By adopting the above technical solution, the meshing parts are symmetrically distributed on both sides of the flexible part, and the force is balanced when meshing with the rotating roller, reducing the deviation or skewing of the flexible belt caused by force, ensuring that the flexible belt moves stably along a straight line. After the flexible part is tensioned, it forms a flat bearing surface, ensuring that the cardboard is placed stably. When the edge-feeding mechanism presses down, the flexible part can generate local indentations with the pressure, forming a "clamping force" concentrated at the cardboard notch. As the pressure increases, the flexible part generates local indentations at the corresponding positions of the notches, pressing the cardboard into the indentations and strengthening the stress concentration at the notches. When the stress exceeds the tear resistance limit of the notch, the cardboard breaks along the notch. At this time, the deformation of the flexible part will rebound quickly as the pressure is released, avoiding additional pulling on the broken cardboard, reducing the rigid impact of the rigid conveyor on the cardboard, and reducing material damage. After the edge-dropping mechanism is lifted, the flexible part returns to flatness and does not hinder the cardboard from continuing to be conveyed with the belt. The sliding part can limit the lateral displacement of the flexible belt. Combined with the symmetrical force of the meshing part, it further prevents the belt from shifting due to vibration and uneven load during long-term operation, and improves the smoothness of the flexible belt conveyor.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By continuously conveying the conveyor mechanism and automatically pressing and tearing the edge-dropping mechanism, the entire process of cardboard edge-dropping is automated, eliminating the need for manual intervention. This significantly increases the throughput per unit time, meeting the needs of large-scale packaging box production. Furthermore, traditional direct cutting methods easily damage the cardboard fiber structure. This equipment utilizes the "pre-fracture" foundation of pre-marking or fine lines, achieving tearing through precise pressing of the edge-dropping mechanism. During pressing, the force is evenly applied to the marked area through the buffer of the flexible belt, reducing the damage of instantaneous impact force to non-marked areas of the cardboard and minimizing the risk of uncontrolled tearing (such as irregular edges or excessive fiber breakage). This addresses the low efficiency of manual edge-dropping while reducing the damage to materials caused by traditional cutting, achieving efficient and high-quality automatic edge-dropping of cardboard. 2. When materials need to be conveyed, the rotary drive is activated, which drives the rotary roller connected to the output end of the rotary drive to rotate. Through meshing with the flexible belt, the flexible belt moves along the tangential direction of the rotary roller. At the same time, other rotary rollers rotate synchronously with the belt under the meshing action of the flexible belt, forming a cyclical motion of the entire conveying path. The rotary drive is directly connected to the drive roller, and the meshing transmission between the flexible belt and the rotary roller reduces the possibility of material accumulation or uneven spacing caused by speed fluctuations. At the same time, it reduces transmission failure caused by belt slack and improves the reliability of equipment operation. 3. The meshing parts are symmetrically distributed on both sides of the flexible part. When meshing with the rotating roller, the force is balanced, reducing the deviation or skewing of the flexible belt caused by the force, ensuring that the flexible belt moves stably along a straight line. After the flexible part is tensioned, it forms a flat bearing surface, ensuring that the cardboard is placed stably. When the edge-dropping mechanism presses down, the flexible part can produce local indentation with the pressure, forming a "clamping force" concentrated at the cardboard score. As the pressure increases, the flexible part produces local indentation at the corresponding position of the score, pressing the cardboard into the indentation and strengthening the stress concentration at the score. When the stress exceeds the tear resistance limit of the score, the cardboard breaks along the score. At this time, the deformation of the flexible part will rebound quickly with the release of pressure, avoiding additional pulling on the broken cardboard, reducing the rigid impact of the rigid conveyor on the cardboard, and reducing material damage.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an automatic edge-trimming device for cardboard packaging boxes.

[0035] Reference Figure 1 and Figure 2 An automatic edge-trimming device for cardboard packaging boxes includes a frame 1, an integrating mechanism, a conveying mechanism, and an edge-trimming mechanism. A control console 11 is fixedly connected to one side of the frame 1. The control console 11 is used to control the operation of the device and is electrically connected to the integrating mechanism, the conveying mechanism, and the edge-trimming mechanism. A feeding drive screw 2 is rotatably connected to the frame 1. The frame 1 has a worktable 12, and the feeding drive screw 2 is located at the bottom of the worktable 12. A feeding port is opened on one side of the frame 1, and the worktable 12 is located at the feeding port. The worktable 12 is fixedly connected to the frame 1. A sliding groove 121 is opened through the top wall of the worktable 12, and a sliding block 21 is attached to the sliding groove 121. The sliding block 21 is threadedly connected to the feeding drive screw 2. A feeding drive component 22 is fixedly connected to the frame 1 and is electrically connected to the control console 11. The feeding drive component 22 is located on the worktable 12. At the bottom, the output end of the feeding drive 22 is fixedly connected to the end of the feeding transmission screw 2 away from the frame 1. The length direction of the sliding groove 121 is parallel to the length direction of the feeding and the feeding transmission screw 2. In a preferred embodiment, the feeding drive 22 is a drive motor. The integration mechanism is located in the conveying direction of the feeding transmission screw 2. The integration mechanism is used to integrate the cardboard. The conveying mechanism is used to receive the integrated cardboard. The conveying mechanism includes a conveying drive assembly and a flexible belt 3. The conveying drive assembly is mounted on the frame 1. The conveying drive assembly is used to drive the flexible belt 3 to move. The conveying drive assembly is electrically connected to the control console 11. The edge-dropping mechanism is located on the top of the flexible belt 3. The edge-dropping mechanism slides against the frame 1, and the sliding direction of the edge-dropping mechanism is vertical. The edge-dropping mechanism is used to press the cardboard on the flexible belt 3 to tear the cardboard at the scratches or fine lines.

[0036] When performing edge trimming on cardboard, loose or stacked cardboard pieces are placed on the worktable 12, positioned on the side of the sliding block 21 closest to the integration mechanism. The feeding drive 22 is activated, causing the feeding transmission screw 2 to rotate. The sliding block 21, threadedly connected to the feeding transmission screw 2, moves along the sliding groove 121 of the worktable 12. The sliding groove 121 guides the sliding block 21, which then feeds the cardboard to the integration mechanism. The integration mechanism aligns and organizes the stacked or loose cardboard pieces, ensuring neat edges. The integrated cardboard is then transferred to the flexible belt 3 of the conveyor mechanism. The control console 11 then moves the cardboard to the conveyor drive. The component sends a command, the conveyor drive component starts and drives the flexible belt 3 to move at a preset speed and direction, smoothly conveying the cardboard to the working area below the edge-cutting mechanism. The control console 11 controls the edge-cutting mechanism to operate according to the preset program. The edge-cutting mechanism applies downward pressure to the cardboard on the flexible belt 3. Because the flexible belt 3 has a certain elasticity, during the pressing process, the cardboard is subjected to the pressure of the edge-cutting mechanism and the reverse support force of the flexible belt 3. The force is concentrated at the notch or fine line, causing the cardboard to tear along that position, completing the edge-cutting. This improves the low efficiency of manual edge-cutting and reduces the damage to the material caused by traditional cutting, achieving efficient and high-quality automatic edge-cutting of cardboard.

[0037] Reference Figure 2 and Figure 3 The integration mechanism includes a first integration component, a suction cup component, a sliding drive component, and a second integration component. The first integration component is slidably connected to the frame 1. The suction cup component is used to pick up the cardboard. The suction cup component slides with the frame 1. The sliding drive component is used to drive the suction cup component to slide to the top of the conveying mechanism. The second integration component is slidably connected to the frame 1. The integration direction of the second integration component is perpendicular to the integration direction of the first integration component.

[0038] After the cardboard is delivered to the integration mechanism, the first integration component slides along the frame 1, approaches the cardboard from a certain direction and applies a pushing force to align stacked or scattered cardboard in that direction. After integration in the first direction is completed, the suction cup component slides along the frame 1 to the top of the cardboard and picks up a cardboard through negative pressure. The second integration component slides along the frame 1 and pushes the cardboard from a direction perpendicular to the first integration component to ensure that the cardboard remains regular in two vertical directions in the plane, reducing the impact of skew in one direction on the subsequent edge-cutting accuracy. Subsequently, the sliding drive component is activated, driving the suction cup component to slide to the top of the conveyor mechanism and place the picked-up cardboard smoothly on the flexible belt 3 of the conveyor mechanism. Through the automated operation of the mechanical components, the integration mechanism realizes the fully unmanned operation of the cardboard from alignment after being pushed to transfer to the conveyor mechanism. This not only reduces the intensity of manual labor but also reduces integration errors through the stability of mechanical transmission, improves the consistency of regularity of each batch of cardboard, lays the foundation for the stable operation of subsequent processes, and reduces material waste and rework costs caused by improper integration.

[0039] The first integrated component includes a first guide plate 4, a second guide plate 41, and a guide drive 42. The first guide plate 4 is fixedly connected to the top wall of the worktable 12. The second guide plate 41 is slidably connected to the worktable 12. The sliding direction of the second guide plate 41 is perpendicular to the sliding direction of the sliding block 21. The guide drive 42 is fixedly connected to the frame 1 and is located at the bottom of the worktable 12. The output end of the guide drive 42 is fixedly connected to the second guide plate 41. The guide drive 42 is used to drive the second guide plate 41 to move closer to or away from the first guide plate 4. The guide drive 42 is electrically connected to the control console 11.

[0040] When the sliding block 21 pushes the cardboard between the first guide plate 4 and the second guide plate 41, the guide drive 42 is activated. The output end of the guide drive 42 drives the second guide plate 41 to move towards the first guide plate 4. The second guide plate 41 gradually approaches the edge of the cardboard and applies a steady pushing force to the cardboard, so that the edge of the cardboard away from the second guide plate 41 fits against the fixed first guide plate 4, thereby realizing the initial integration operation of the cardboard.

[0041] A support rod 43 is fixedly connected to the top of the workbench 12, and an integrated frame 44 is fixedly connected to the top of the support rod 43. The first guide plate 4 and the second guide plate 41 both extend to the bottom of the integrated frame 44, so that the cardboard moves smoothly and neatly to the bottom of the integrated frame 44 under the action of the second guide plate 41 of the first guide plate 4.

[0042] The sliding drive assembly is located on the top of the worktable 12. The sliding drive assembly includes a sliding drive component 5, a sliding transmission screw 51, and a sliding guide rod 52. The sliding drive component 5 is electrically connected to the control console 11 and is fixedly connected to the frame 1. The output end of the sliding drive component 5 is fixedly connected to the sliding transmission screw 51. The sliding transmission screw 51 is rotatably connected to the frame 1. The suction cup assembly is threadedly connected to the sliding transmission screw 51. The sliding guide rod 52 is fixedly connected to the frame 1. The length direction of the sliding guide rod 52 is parallel to the length direction of the sliding transmission screw 51. The suction cup assembly is slidably connected to the sliding guide rod 52. In a preferred embodiment, the sliding drive component 5 is a drive motor.

[0043] When the sliding block 21 pushes the cardboard into the integrated frame 44, the sliding block 21 stops pushing the cardboard. The sliding drive 5 receives the control signal from the control console 11 and starts. The output end of the sliding drive 5 drives the sliding transmission screw 51 to rotate. The sliding connection between the suction cup assembly and the sliding guide rod 52 restricts the tendency of the suction cup assembly to rotate with the sliding transmission screw 51, so that the rotational motion of the sliding transmission screw 51 is converted into linear driving force through the threaded pair, which moves the cardboard from the paper picking position to the top of the conveying mechanism, improving the stability of the cardboard movement.

[0044] Furthermore, the suction assembly includes a movable seat 53, a lifting drive 54, and a suction plate 55. The movable seat 53 slides with the frame 1. Specifically, the movable seat 53 is threadedly connected to the sliding transmission screw 51 and the movable seat 53 is slidably connected to the sliding guide rod 52. The lifting drive 54 is fixedly connected to the movable seat 53, and the output end of the lifting drive 54 is fixedly connected to the suction plate 55. The lifting drive 54 is electrically connected to the control console 11. In a preferred embodiment, the lifting drive 54 is a drive motor.

[0045] After the first integration component completes the integration operation, the lifting drive 54 is activated, which drives the suction plate 55 to move, so that the suction plate 55 can pick up the cardboard. The suction plate 55 uses negative pressure to adsorb the cardboard, which reduces the squeezing of the cardboard edges compared with mechanical clamping, and can effectively reduce the possibility of cardboard wrinkles and deformation of thick cardboard.

[0046] The second integrated component includes a connecting frame 56, a push plate 57, and a support member 58. The connecting frame 56 is slidably connected to the frame 1. In a preferred embodiment, the connecting frame 56 can be slidably connected to the frame 1 in a horizontal direction via pneumatic transmission. The connecting frame 56 is slidably connected to the push plate 57. A push drive member 59 is fixedly connected to the connecting frame 56. The push drive member 59 is electrically connected to the control console 11. The output end of the push drive member 59 is fixedly connected to the top wall of the push plate 57. The push drive member 59 is used to drive the push plate 57 to move up and down. The support member 58 is fixedly connected to the side of the push plate 57 near the conveying mechanism.

[0047] When the first guide plate 4 and the second guide plate 41 complete the unidirectional integration of the cardboard, and the cardboard is located directly below the integration frame 44, the suction cup 55 picks up the cardboard to a certain height, which is higher than the top wall of the integration frame 44. The connecting frame 56 moves towards the direction of the conveying mechanism, and the push plate 57 is raised and lowered to support the bottom of the cardboard. One side of the push plate 57 applies a horizontal pushing force to the side of the cardboard, so that the cardboard is aligned on one side in the direction perpendicular to the horizontal plane of the first integration direction, thus completing the bidirectional integration. The cardboard is neat in both vertical directions in the plane, reducing the problems of cardboard skewing and uneven edges, and providing a more accurate position reference for subsequent suction cup picking, conveying and edge finishing processes.

[0048] The support member 58 includes a connecting part 581 and a rotating part 582. The connecting part 581 is fixedly connected to the side of the push plate 57 near the conveying mechanism. The rotating part 582 is rotatably connected to the connecting part 581, and the rotation axis of the rotating part 582 is perpendicular to the sliding direction of the sliding block 21. In the vertical direction, the outer wall of the rotating part 582 protrudes from the bottom wall of the connecting part 581.

[0049] When the cardboard moves to the area of ​​the first integration component, the push plate 57 is lowered, causing the rotating part 582 to fit against the top wall of the cardboard stack. The rotating part 582 limits the top direction of the cardboard. When the first integration component is integrated, the possibility of the cardboard warping is reduced, and the integration flatness of the cardboard is further improved.

[0050] The conveying drive assembly includes a rotating drive component 6 and a rotating roller 61. The rotating drive component 6 is electrically connected to the control console 11 and is fixedly connected to the frame 1. The rotating roller 61 is rotatably connected to the frame 1. Multiple rotating rollers 61 are provided. The output end of the rotating drive component 6 is fixedly connected to one of the rotating rollers 61. The flexible belt 3 meshes with the rotating roller 61.

[0051] When materials need to be conveyed, the rotation drive 6 is activated, which drives the rotating roller 61 connected to the output end of the rotation drive 6 to rotate. Through meshing with the flexible belt 3, the flexible belt 3 moves along the tangential direction of the rotating roller 61. At the same time, other rotating rollers 61 rotate synchronously with the belt under the meshing action of the flexible belt 3, forming a cyclical motion of the entire conveying path. The rotation drive 6 is directly connected to the drive roller, and the meshing transmission between the flexible belt 3 and the rotating roller 61 reduces the possibility of material accumulation or uneven spacing caused by speed fluctuations. At the same time, it reduces transmission failure caused by belt slack and improves the reliability of equipment operation.

[0052] Reference Figure 2 and Figure 4 The flexible belt 3 includes an engaging part 31, a flexible part 32, and a sliding part 33. The engaging part 31 engages with the rotating roller 61. The engaging part 31 is symmetrically arranged on both sides of the conveying direction of the flexible part 32. The side of the engaging part 31 away from the flexible part 32 is fixedly connected to the sliding part 33. The frame 1 has a sliding groove. The sliding part 33 is inserted into the sliding groove. The end of the sliding part 33 near the engaging part 31 is cylindrical, and the end away from the engaging part 31 is spherical. The spherical part slides on the groove wall of the sliding groove. The flexible part 32 is coiled around the rotating roller 61 and is in a tensioned state.

[0053] The engaging portions 31 are symmetrically distributed on both sides of the flexible portion 32. When engaging with the rotating roller 61, they are subjected to balanced forces, reducing the deviation or skewing of the flexible belt 3 caused by force, and ensuring that the flexible belt 3 moves stably along a straight line. After tensioning, the flexible portion 32 forms a flat bearing surface, ensuring that the cardboard is placed stably. When the edge-feeding mechanism presses down, the flexible portion 32 can generate local indentations with the pressure, forming a "clamping force" concentrated at the cardboard notch. As the pressure increases, the flexible portion 32 generates local indentations at the corresponding positions of the notches, pressing the cardboard into the indentations and strengthening the stress concentration at the notches. When the stress exceeds the tear resistance limit of the notch, the cardboard breaks along the notch. At this time, the deformation of the flexible part 32 will rebound quickly as the pressure is released, avoiding additional pulling on the broken cardboard, reducing the rigid impact of the rigid conveyor on the cardboard, and reducing material damage. After the edge dropping mechanism is lifted, the flexible part 32 returns to flatness and does not hinder the cardboard from continuing to be conveyed with the belt. The sliding part 33 can limit the lateral displacement of the flexible belt 3. With the symmetrical force of the meshing part 31, it further prevents the belt from shifting due to vibration and uneven load during long-term operation, and improves the conveying stability of the flexible belt 3.

[0054] The rotating roller 61 has a guide groove 611, and the flexible part 32 is inserted into the guide groove 611. The guide groove 611 is used to guide the flexible part 32. The flexible part 32 is in the form of a grid with crisscrossing directions, wherein the transverse direction is perpendicular to the sliding direction of the sliding block 21.

[0055] To further improve the tearing quality of the cardboard, a support platform is fixedly connected to the frame 1. The support platform supports the flexible part 32. The support platform is located at one end of the flexible belt 3 near the integrated frame 44 in the conveying direction. The support platform directly below the edge-feeding mechanism does not support the flexible part 32, making it easier to press.

[0056] The frame 1 is fixedly connected to a waste rack 9. The waste rack 9 is located at the end of the flexible part 32 away from the integrated frame 44 in the conveying direction. The inner bottom wall of the waste rack 9 is inclined, and the horizontal height of the end away from the flexible part 32 is lower than the horizontal height of the end close to the flexible part 32. The end of the waste rack 9 with the lower horizontal height is located at the bottom of the flexible part 32. The bottom of the flexible part 32 is provided with a discharge mechanism 91. In a preferred embodiment, the discharge mechanism 91 adopts a conveyor belt structure, which will not be described in detail here. The waste rack 9 is used to transport the waste material transmitted from the flexible part 32 to the discharge mechanism 91.

[0057] Reference Figure 2 and Figure 5The edge-cutting mechanism includes a movable plate 7, a movable drive component 71, a pressing plate 72, and edge-cutting blocks 74. The movable plate 7 is slidably connected to the frame 1, and the sliding direction is parallel to the sliding direction of the sliding block 21. In a preferred embodiment, the movable plate 7 is driven to slide on the frame 1 by a transmission method combining a motor and a lead screw. The movable drive component 71 is fixedly connected to the movable plate 7 and electrically connected to the control console 11. The output end of the movable drive component 71 is fixedly connected to the top wall of the pressing plate 72. The movable drive component 71 is used to drive the pressing plate 72 to rise and fall. The edge-cutting blocks 74 are fixedly connected to the bottom wall of the pressing plate 72. There are multiple edge-cutting blocks 74. The edge-cutting blocks 74 are assembled to form a pressing area for pressing the cardboard, which facilitates the tearing of the cardboard. Specifically, when the edge-cutting blocks 74 press the cardboard, the etched part of the cardboard is located in the pressing area.

[0058] The pressing plate 72 has an adsorption hole 73, which is located in the gap formed by the edge dropping block 74. The adsorption hole 73 is connected to an externally installed vacuum pump through a pipe. The adsorption hole 73 provides adsorption force through the vacuum pump, so that the cardboard is adsorbed onto the edge dropping block 74.

[0059] A movable platform 8 is provided at the end of the waste rack 9 away from the flexible part 32. The movable platform 8 is slidably connected to the frame 1. In a preferred embodiment, the movable platform 8 is driven to slide on the frame 1 by a transmission method combining a motor and a lead screw. A support drive component 81 is fixedly connected to the top wall of the movable platform 8. The support drive component 81 is electrically connected to the control console 11. The output end of the support drive component 81 is connected to a receiving platform 82. In a preferred embodiment, the support drive component 81 is a hydraulic cylinder.

[0060] The implementation principle of the automatic edge-trimming device for cardboard packaging boxes in this embodiment is as follows: When performing edge-trimming operation on cardboard, scattered or stacked cardboard pieces are placed on the worktable 12, located on the side of the sliding block 21 close to the integration mechanism. The feeding drive 22 is activated, which drives the feeding transmission screw 2 to rotate. The sliding block 21, which is threadedly connected to the feeding transmission screw 2, moves along the sliding groove 121 of the worktable 12. The sliding groove 121 guides the direction of the sliding block 21. The push drive 59 is activated, which moves the push plate 57 down to fit against the worktable. 12. The sliding block 21 pushes the cardboard to fit against the push plate 57, thus initially integrating the cardboard. The push drive 59 drives the push plate 57 upward, allowing the cardboard to pass through the gap between the push plate 57 and the worktable 12. The sliding block 21 continues to push the cardboard, activating the guide drive 42, which drives the second guide plate 41 to move, aligning the cardboard. This achieves the integration mechanism aligning and organizing stacked or scattered cardboard, ensuring neat edges. The lifting drive 54 is then activated, driving the suction tray 55 to descend. The cardboard at the top layer is sucked up. The lifting drive 54 drives the suction tray 55 to rise, and the connecting frame 56 slides towards the cardboard. The push drive 59 drives the push plate 57 to rise and fall, so that the connecting part 581 is in contact with the cardboard. The connecting part 581 supports the cardboard. The connecting plate slides, and the push plate 57 pushes the cardboard. Then, the sliding drive 5 is activated. The sliding drive 5, through the sliding transmission screw 51, drives the moving seat 53 to move directly above the flexible part 32. The suction tray 55 releases the cardboard and places it on the flexible part 32. The rotation... The driving component 6 drives the meshing part 31 to perform transmission, which in turn drives the flexible part 32 to perform transmission until the cardboard is smoothly transported to the working area below the edge-dropping block 74. The edge-dropping block 74 descends and applies downward pressing pressure to the cardboard on the flexible belt 3. Since the flexible belt 3 has a certain elasticity, during the pressing process, the cardboard is subjected to the pressure of the edge-dropping mechanism and the reverse support force of the flexible belt 3. The force is concentrated at the notch or fine line, causing the cardboard to tear along that position, thus completing the edge-dropping. This improves the low efficiency of manual edge-dropping and reduces the damage to the material caused by traditional cutting, achieving efficient and high-quality automatic edge-dropping of cardboard.

These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
