Description

Technical Field

[0001] This invention relates to the field of packaging box processing, and more specifically, to an integrated equipment for intelligent pressing and precise grooving of packaging boxes. Background Technology

[0002] With the upgrading of consumption and intensification of brand competition, the appearance quality and structural stability of high-end packaging boxes (such as hinged boxes and book-shaped boxes) have become key evaluation indicators. Against this backdrop, intelligent pressing technology for packaging boxes has emerged and continues to develop. This technology aims to replace traditional manual or semi-mechanical pressing with automated, programmable pressure control to eliminate bubbles and wrinkles on the box surface, ensuring a crisp, well-defined shape and improving batch consistency. Advanced intelligent pressing systems typically integrate pressure sensing and feedback mechanisms, applying precise and uniform pressure to the box according to preset process parameters, making it a core component in achieving high-quality post-processing of packaging boxes.

[0003] In the crucial pre-processing steps of packaging box forming, intelligent precision grooving technology has become the industry standard for achieving complex box shapes and delicate creases. This technology mainly refers to high-precision grooving equipment based on computer numerical control (CNC) systems. Through program control of a high-speed spindle and precision cutting tools, it cuts V-shaped or irregularly shaped grooves of uniform depth and width on the laminated cardboard. Compared to traditional die-cutting or semi-automatic grooving, intelligent precision grooving technology has significant advantages such as high repeatability (up to ±0.1mm), strong adaptability to complex shapes, and rapid design changes. It lays a reliable "skeleton" foundation for the precise folding of packaging boxes and is a prerequisite for ensuring the final formed dimensions and aesthetics.

[0004] Despite significant progress in both intelligent pressing and precision grooving technologies, attempts to deeply integrate their functions and build truly unified intelligent molding equipment still face considerable challenges. Currently, most production processes still treat grooving and pressing as two separate, physically isolated workstations, resulting in low material flow efficiency, large equipment footprint, and difficulties in overall coordinated control. More importantly, even in the few attempts at integration, the technical solutions for the pressing module often have fundamental limitations. For example, existing structures used for pressing down packaging boxes generally rely on the physical structure of cylinders and springs. Their output pressure is affected by fluctuations in the air source, friction, and spring fatigue, making real-time precise control and closed-loop feedback impossible. Furthermore, simple single-point or small-area pressing methods can easily lead to uneven pressure distribution on the box surface, potentially causing quality defects such as localized deformation or weak corner joints. For example, in the Chinese invention patent application number 202411966842.2 entitled "An Automatic Box Pressing Machine," the pressing mechanism is driven by a cylinder to drive the pressing plate, and relies on springs for buffering and reset. The height of the pressing plate needs to be manually adjusted mechanically. This structure clearly reveals that in existing integrated attempts, the pressing unit is still in the open-loop, rudimentary pneumatic control stage, which is difficult to meet the increasingly precise, flexible, and traceable requirements of high-end packaging boxes for pressing processes. Therefore, developing an integrated device that can deeply integrate high-precision grooving and highly intelligent pressing functions, and overcome the above-mentioned pressure control defects, has become a technical problem that the industry urgently needs to solve. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies: existing structures for pressing down packaging boxes rely on the physical structure of cylinders and springs, and the pressure cannot be precisely controlled in real time; single-point pressing may lead to uneven pressure distribution, local deformation of the box or weak corner bonding, and the proposed intelligent pressing and precise grooving integrated equipment for packaging boxes.

[0006] The specific technical solution is as follows: an integrated intelligent pressing and precise grooving equipment for packaging boxes, including a grooving machine and an intelligent pressing machine for packaging boxes mounted on a base. The grooving machine is used for precise grooving of the packaging boxes, and the intelligent pressing machine is used for pressing the packaging boxes. The intelligent pressing machine includes a pressing mechanism, which includes a gantry frame mounted on the base and a pressing assembly mounted on the gantry frame. The pressing assembly includes a servo electric cylinder A and a pressing plate structure. The pressing plate structure is mounted on the servo electric cylinder A, and the servo electric cylinder A is mounted on the gantry frame. The servo electric cylinder A is used to precisely control the pressing pressure of the pressing plate structure. The pressing plate structure includes a pressing plate, which includes multiple unit pressing plates arranged in multiple rows and columns. Each unit pressing plate is equipped with a servo electric cylinder B. The servo electric cylinder B on one or more unit pressing plates independently controls the outward protrusion and pressing force of the unit pressing plate, which is used to adapt to the shape pressing of the packaging box in all directions and to accurately adjust the pressure for different areas of the packaging box.

[0007] In a further technical solution of the present invention, the pressing plate structure further includes a limiting base plate, which is mounted on the servo electric cylinder A; the pressing plate is mounted on the limiting base plate; wherein, multiple unit pressing plates are installed in multiple rows and columns on the limiting base plate; each unit pressing plate is equipped with a pressure sensor, which is used to provide real-time feedback on the pressure exerted by the unit pressing plate on the packaging box.

[0008] A further technical solution of the present invention also includes an operation panel, on which a control system is connected. The control system is electrically connected to the intelligent packaging box pressing machine and the fully automatic CNC grooving machine included in the grooving machine. The control system includes a process gene map construction and analysis center, a deformation field real-time perception and twin synchronization engine, a deformation field collaborative shaping decision and execution device, and a full-cycle evolutionary learning and map self-evolution platform.

[0009] A further technical solution involves a process gene mapping construction and analysis center used to establish and analyze a physical law model governing the entire packaging box forming process. This process gene mapping construction and analysis center includes:

[0010] A. Multi-scale material-structure gene library, storing or acquiring in real time cross-scale data of packaging materials, from microscopic fiber orientation and mesoscopic laminated structure to macroscopic geometric features;

[0011] B. Unified Deformation Field Characterization Model: The grooving cutting and pressing plastic deformation are uniformly modeled as a continuous medium deformation field that evolves with time. This model uses a set of partial differential equations to describe the dynamic relationship between the internal stress, strain energy density and external process load of the material.

[0012] C. Process Gene Map Compiler: Taking the digital model of the target box and material gene data as input, a global process gene map is compiled in reverse by solving the deformation field equation. This map is a dynamic program network that defines the force functions, motion trajectory functions and interlocking relationships of each execution unit of the equipment in each processing stage, including slotting, pre-pressing and final pressing.

[0013] The real-time deformation field sensing and twin synchronization engine is used to maintain millisecond-level synchronization with the digital world during physical processing. The real-time deformation field sensing and twin synchronization engine includes:

[0014] A. Domain multimodal sensing array, integrating optical, acoustic and force sensors, to capture the three-dimensional morphology, subsurface stress wave and acoustic emission signal of the processing interface in real time with ultra-high spatiotemporal resolution;

[0015] B. Dynamic twin incremental updater, based on real-time sensing data stream, incrementally corrects the boundary conditions and parameters of the unified characterization model of the deformation field online, so that the deformation state of the digital twin and the physical world can achieve three-temporal synchronous calibration of advance, real-time and lag, wherein advance synchronization is used to predict the deformation trend in the next few milliseconds.

[0016] The deformation field collaborative shaping decision and actuator connects the aforementioned central hub and engine, and includes:

[0017] A. Band theory-based collaborative optimizer: The deformation field state at the current moment is mapped to an abstract "process energy band" space. The optimization algorithm finds a path in the energy band with the lowest global energy consumption and the lowest risk of quality defects. This path is directly translated into the next set of collaborative control instructions for the slotting and pressing execution units.

[0018] B. Bionic Cluster Actuator Network: Physical actuators are organized into a bionic cluster with local perception, decision-making and action capabilities. Each unit receives macroscopic intent from the co-optimizer and combines it with its local sensor information. Through coupling rules that mimic ant colonies or neural impulses, it self-organizes and coordinates with neighboring units to jointly achieve stable and uniform shaping of the deformation field.

[0019] The full-cycle evolutionary learning and graph self-evolution platform is used to realize the autonomous growth of system capabilities. It encapsulates the full-link data of each processing task into a process experiment. By comparing the final state difference between the predicted deformation field and the actual deformation field, it automatically iteratively optimizes the logical rules and parameters of the process gene graph compiler, so that the compilation capability of the graph continues to evolve with the accumulation of processing experience, and can transfer the evolution results between similar devices through a security protocol.

[0020] A further technical solution involves a reverse compilation process executed by the process gene map compiler, which specifically includes a defect inversion and elimination step: first, in a digital twin environment, the defect morphologies that may be generated by the standard process path, such as pressing wrinkles and grooving edge bursts, are simulated; then, the key stress singularities that lead to the defect morphology and their evolution process in the deformation field are traced back in reverse; finally, by adjusting the force function on the corresponding spatiotemporal coordinates in the map, the possibility of the defect being generated is eliminated from the root.

[0021] A further technical solution involves a band theory-based collaborative optimizer that optimizes the quality of a single processing step during decision-making. Simultaneously, it introduces actuator health and tool wear status as optimization variables. Under the premise of ensuring forming quality, it dynamically balances the workload of each execution unit to achieve multi-objective Pareto optimality for processing quality and equipment life.

[0022] In a further technical solution, the biomimetic cluster actuator network, during the pressing stage, uses local coupling rules to simulate the electrical signal conduction mechanism of cardiomyocytes: when a pressing unit detects yielding or abnormal slippage of the material below it, it generates an inhibitory signal wave that diffuses to the surrounding units, guiding the surrounding units to adjust the pressure instantaneously and adaptively, forming a dynamic protective pressure ring to prevent the spread of defects.

[0023] In a further technical solution, before the grooving process is started, the system predicts the overall warping mode of the board that may be caused by the grooving process based on the process gene map, and in advance instructs a specific pressing unit on the pressing side to apply a precise prestress field to counteract the warping trend, thereby achieving proactive control of stabilizing the shape before grooving.

[0024] This invention provides an integrated intelligent pressing and precise grooving device for packaging boxes, which, compared with existing technologies, can achieve the following:

[0025] 1. After pre-processing by the grooving machine and the intelligent packaging box pressing machine, the pressing assembly uses servo electric cylinder A to precisely control the downward pressure of the pressing plate structure; during the pressing of the packaging box by the pressing plate structure, servo electric cylinder B is used independently to control the pressing force of the unit pressing plate, improving the uniformity of force in different areas; and the outward protrusion and pressing force of the unit pressing plate can be independently controlled by servo electric cylinder B on one or more unit pressing plates, so as to fully adapt to the shape pressing of the packaging box and to accurately adjust the pressure for different shapes in different areas of the packaging box.

[0026] 2. Existing technologies treat grooving and pressing as discrete events and link or coordinate them; the deformation field unified characterization model of the present invention describes the entire process in a unified manner from the bottom layer of continuous medium mechanics, enabling the control system to theoretically have the ability to perform global consistency optimization, which is a fundamental paradigm shift.

[0027] 3. Traditional control follows a forward logic of "given instruction → execution → deviation → compensation"; the process gene map compiler of this invention uses reverse thinking: starting from the desired defect-free final state, it reversely derives the optimal process path to achieve the final state and eliminates the possibility of defects in advance, realizing a qualitative change in control logic from treating the disease to preventing the disease.

[0028] 4. Existing multi-agent systems have not yet completely broken free from central scheduling; the biomimetic clustered actuator network proposed in this invention is inspired by biological tissues, endowing each execution unit with the ability to self-organize and coordinate based on simple local rules. The system as a whole exhibits robust, adaptive, and fault-tolerant life-like intelligence, which is an innovation in the architecture of large-scale precision execution systems.

[0029] 5. This invention enables the process gene map itself to learn and evolve through a full-cycle evolutionary learning platform; it can not only optimize parameters, but also optimize the underlying logic and rules of the generated process, like a master craftsman who constantly accumulates experience, forming a truly difficult-to-replicate core process knowledge base and a continuously evolving technological barrier.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0045] In embodiments of the present invention, such as Figure 1 , Figure 2 , Figures 4-6 As shown: The packaging box intelligent pressing and precision grooving integrated equipment includes a grooving machine 100 and a packaging box intelligent pressing machine 200 mounted on a base 500. The grooving machine 100 is used for precise grooving of packaging boxes, and the packaging box intelligent pressing machine 200 is used for pressing packaging boxes.

[0046] As for the base 500, it should be further explained that: the base 500 is equipped with a conveyor belt 400. The conveyor belt 400 and the slotting machine 100 are both existing technologies and can be purchased directly on the market or assembled by purchasing parts, etc. Whether they are publicly available or not does not affect the control system of the intelligent packaging box pressing machine 200 and the slotting machine 100 that are to be protected. They will not be elaborated on here.

[0047] The intelligent packaging box pressing machine 200 includes a pressing mechanism 300, which includes a gantry frame 310 mounted on a base 500 and a pressing assembly 320 mounted on the gantry frame 310. The pressing assembly 320 includes a servo electric cylinder A321 and a pressing plate structure 322. The pressing plate structure 322 is mounted on the servo electric cylinder A321, which is mounted on the gantry frame 310. The servo electric cylinder A321 is used to precisely control the pressing pressure of the pressing plate structure 322.

[0048] The pressing plate structure 322 includes a pressing plate 3222, which includes multiple unit pressing plates 3223. The multiple unit pressing plates 3223 are arranged in multiple rows and columns and are attached to each other. Each unit pressing plate 3223 is equipped with a servo electric cylinder B. The servo electric cylinder B on one or more unit pressing plates 3223 can independently control the protrusion degree and pressing force of the unit pressing plate 3223, so as to adapt to the shape pressing of the packaging box in all directions and to adjust the pressure accurately for different areas of the packaging box.

[0049] Regarding the specific number of "multiple unit pressing plates 3223", it can be two, three, four, five, etc., and there is no limit to the exact number, as long as it can meet the requirement that the protrusion degree and pressing force of the unit pressing plates 3223 can be independently controlled by the servo electric cylinder B on one or more unit pressing plates 3223, so as to adapt to the different shapes of different areas of the packaging box; here, nine are preferred.

[0050] Therefore, after the pre-processing by the slotting machine 100 and the intelligent packaging box pressing machine 200, the pressing assembly 320 uses a servo electric cylinder A321 to precisely control the downward pressure of the pressing plate structure 322. During the pressing process of the pressing plate structure 322, the pressing force of the unit pressing plate 3223 is controlled independently by the servo electric cylinder B to improve the uniformity of force in different areas. Furthermore, the degree of protrusion and pressing force of the unit pressing plate 3223 can be independently controlled by the servo electric cylinder B on one or more unit pressing plates 3223, which is used to adapt to the shape pressing of the packaging box in all directions and to accurately adjust the pressure for different shapes in different areas of the packaging box.

[0051] In embodiments of the present invention, such as Figure 5 and Figure 6 As shown: The pressing plate structure 322 also includes a limiting base plate 3221, which is mounted on the servo electric cylinder A321; the pressing plate 3222 is mounted on the limiting base plate 3221; wherein, multiple unit pressing plates 3223 are installed in multiple rows and columns on the limiting base plate 3221; each unit pressing plate 3223 is equipped with a pressure sensor, which is used to provide real-time feedback on the pressure exerted by the unit pressing plate 3223 on the packaging box.

[0052] Pressure sensors are existing technology, and their detailed structure can be found in existing literature and journals. They can also be purchased directly from the market or assembled from components purchased from the market. They are not the subject of this invention and will not be described in detail here, nor are they shown in the accompanying drawings.

[0053] In embodiments of the present invention, such as Figures 4-6 The servo electric cylinder A321 and servo electric cylinder B adopt the same structure. The servo electric cylinder A321 includes a servo motor 3211, a driver, and a ball screw transmission component 3213. The servo motor 3211 and the driver are mounted on a support box 3212, which is mounted on a gantry frame 310. The servo motor 3211 and the driver are connected to the ball screw transmission component 3213 through the support box 3212. A reinforcing ring 3214 is sleeved on the outside of the ball screw transmission component 3213, and the ball screw transmission component 3213 is inserted and mounted on the gantry frame 310 through the reinforcing ring 3214.

[0054] The ball screw drive component 3213 contains a screw and a nut. A piston rod 3216 is installed at the end of the screw. The piston rod 3216 is assembled on the pressing plate structure 322 through a connecting plate 3215.

[0055] The servo electric cylinders A321 and B, except as described above, are all existing technologies and can be purchased directly on the market or assembled by purchasing parts, etc. Whether they are disclosed or not does not affect the control system of the intelligent packaging box pressing machine 200 and the slotting machine 100 to be protected, and will not be elaborated here.

[0056] In embodiments of the present invention, such as Figure 3 As shown: The gantry frame 310 includes a crossbeam 311 and two support plates 312. The two support plates 312 are distributed at both ends of the crossbeam 311 and are perpendicular to the crossbeam 311. The crossbeam 311 is provided with a groove for mounting the servo electric cylinder A321. The support plate 312 has a mounting plate 313 fixed at the end away from the crossbeam 311. The mounting plate 313 is mounted on the base 500 by multiple bolts 314.

[0057] In embodiments of the present invention, such as Figure 1 As shown: It also includes an operation panel 600, on which a control system is connected. The control system's electrical signals are connected to the intelligent packaging box pressing machine 200 and the fully automatic CNC grooving machine included in the grooving machine 100.

[0058] The control system includes a process gene map construction and analysis center, a deformation field real-time perception and twin synchronization engine, a deformation field collaborative shaping decision and execution device, and a full-cycle evolutionary learning and gene map self-evolution platform.

[0059] Furthermore, the process gene mapping construction and analysis center is used to establish and analyze the physical law model governing the entire packaging box forming process. The process gene mapping construction and analysis center includes:

6. The integrated intelligent pressing and precise grooving equipment for packaging boxes according to claim 5, characterized in that, The process gene mapping construction and analysis center is used to establish and analyze the physical law model governing the entire packaging box forming process. The process gene mapping construction and analysis center includes: A. Multi-scale material-structure gene library, storing or acquiring in real time cross-scale data of packaging materials, from microscopic fiber orientation and mesoscopic laminated structure to macroscopic geometric features; B. Unified Deformation Field Characterization Model: The grooving cutting and pressing plastic deformation are uniformly modeled as a continuous medium deformation field that evolves with time. This model uses a set of partial differential equations to describe the dynamic relationship between the internal stress, strain energy density and external process load of the material. C. Process Gene Map Compiler: Taking the digital model of the target box and material gene data as input, a global process gene map is compiled in reverse by solving the deformation field equation. This map is a dynamic program network that defines the force functions, motion trajectory functions and interlocking relationships of each execution unit of the equipment in each processing stage, including slotting, pre-pressing and final pressing. The real-time deformation field sensing and twin synchronization engine is used to maintain millisecond-level synchronization with the digital world during physical processing. The real-time deformation field sensing and twin synchronization engine includes: A. Domain multimodal sensing array, integrating optical, acoustic and force sensors, to capture the three-dimensional morphology, subsurface stress wave and acoustic emission signal of the processing interface in real time with ultra-high spatiotemporal resolution; B. Dynamic twin incremental updater, based on real-time sensing data stream, incrementally corrects the boundary conditions and parameters of the unified characterization model of the deformation field online, so that the deformation state of the digital twin and the physical world can achieve three-temporal synchronous calibration of advance, real-time and lag, wherein advance synchronization is used to predict the deformation trend in the next few milliseconds. The deformation field collaborative shaping decision and actuator connects the aforementioned central hub and engine, and includes: A. Band theory-based collaborative optimizer: The deformation field state at the current moment is mapped to an abstract "process energy band" space. The optimization algorithm finds a path in the energy band with the lowest global energy consumption and the lowest risk of quality defects. This path is directly translated into the next set of collaborative control instructions for the slotting and pressing execution units. B. Bionic Cluster Actuator Network: Physical actuators are organized into a bionic cluster with local perception, decision-making and action capabilities. Each unit receives macroscopic intent from the co-optimizer and combines it with its local sensor information. Through coupling rules that mimic ant colonies or neural impulses, it self-organizes and coordinates with neighboring units to jointly achieve stable and uniform shaping of the deformation field. The full-cycle evolutionary learning and graph self-evolution platform is used to realize the autonomous growth of system capabilities. It encapsulates the full-link data of each processing task into a process experiment. By comparing the final state difference between the predicted deformation field and the actual deformation field, it automatically iteratively optimizes the logical rules and parameters of the process gene graph compiler, so that the compilation capability of the graph continues to evolve with the accumulation of processing experience, and can transfer the evolution results between similar devices through a security protocol.

9. The integrated intelligent pressing and precise grooving equipment for packaging boxes according to claim 6, characterized in that, During the pressing phase, the biomimetic cluster actuator network uses local coupling rules to simulate the electrical signal transmission mechanism of cardiomyocytes: when a pressing unit detects yielding or abnormal slippage of the material below it, it generates an inhibitory signal wave that diffuses to surrounding units, guiding the surrounding units to adjust the pressure instantaneously and adaptively, forming a dynamic protective pressure ring to prevent the spread of defects.

10. The integrated intelligent pressing and precise grooving equipment for packaging boxes according to claim 6, characterized in that, Before the grooving process begins, the system predicts the overall warping mode of the board that may be caused by the grooving process based on the process gene map, and in advance instructs a specific pressing unit on the pressing side to apply a precise prestress field to counteract the warping trend, thereby achieving proactive control of stabilizing the shape before grooving.
