Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard box production equipment technology, specifically to a multi-layer corrugated cardboard box production equipment and its process. Background Technology

[0002] Currently, the production of multi-layer corrugated boxes mainly relies on mechanized cutting and sorting systems, with visual inspection and cutting typically occurring in separate processes. Existing production lines generally adopt a "test first, cut later" model, where corrugated paper is inspected for defects before entering the cutting station using independent visual inspection equipment, and defective paperboard is rejected before being sent to the cutting machine for processing. While this structure can ensure a certain level of product quality, the separation of inspection and cutting processes leads to complex material transfer between equipment, inconsistent cycle times, and the inability to use inspection data in real time for cutting path correction, easily causing processing deviations and material waste.

[0003] Traditional corrugated paper conveying systems typically employ continuous rotary conveyor belts for feeding the paperboard. However, these structures often lack downward pressure and restraint mechanisms on the paperboard surface. During high-speed conveying, the corrugated paper is prone to warping due to airflow disturbances or mechanical vibrations, affecting subsequent cutting accuracy and visual inspection stability. Furthermore, continuous conveyor belts can cause "dynamic blurring" during the visual inspection stage, where the industrial camera blurs the image due to the continuous movement of the inspected object, thus reducing detection and recognition accuracy.

[0004] Furthermore, existing cutting heads and conveying devices are generally arranged independently, lacking a synchronized control mechanism, and therefore cannot dynamically adjust the cutting path based on detection results. Even in systems that incorporate visual recognition modules, these are mostly post-processed static analysis structures, still requiring manual intervention to correct the cutting trajectory, thus failing to achieve true intelligent detection and real-time defect avoidance.

[0005] In summary, existing technologies generally suffer from the following problems:

[0006] (1) Visual inspection and cutting processing are separated, data transmission is delayed, and online path correction cannot be achieved;

[0007] (2) The conveying structure lacks a pressure holding device, and the corrugated paper is prone to warping and deviation during the transmission process, resulting in cutting errors;

[0008] (3) Traditional rotating conveyor belts move continuously, which is not conducive to stable shooting by industrial cameras, and image recognition is easily affected by the ghosting of the captured photos.

[0009] Therefore, there is an urgent need for a multi-layer corrugated carton production equipment that can integrate visual inspection, path correction, pressing and conveying control to solve problems such as asynchronous inspection and cutting, unstable cardboard posture and inspection ghosting, thereby improving cutting accuracy and production efficiency. Summary of the Invention

[0010] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0011] Therefore, the technical solution adopted by the present invention is: a multi-layer corrugated carton production equipment and process, including a cutting machine table, a machine head base, a pressing assembly and a feeding assembly.

[0012] The cutting machine platform supports and guides the cutting mechanism. Its surface is equipped with a traveling rail and a gantry rail, which drive the headstock to move in the transverse and longitudinal directions, respectively, to achieve two-dimensional controllability of the cutting trajectory. The cutting head (such as a wire saw or laser head) is mounted on the headstock and works in conjunction with a vision inspection system to complete real-time detection, path planning, and dynamic correction of the multi-layer corrugated paper surface.

[0013] In this invention, a lower scanner group arranged in a horizontal array is embedded in the surface of the cutting machine table, and an upper scanner is fixedly installed at the bottom of the machine head base, the two forming a stereo vision detection channel.

[0014] In a preferred example, the signal outputs of both the upper and lower scanners are electrically connected to the vision inspection system for acquiring two-dimensional and three-dimensional images of the corrugated paper surface. The vision inspection system integrates an AI detection module that uses deep learning algorithms to automatically identify and locate defects such as creases, dents, tears, and splicing errors on the corrugated paper surface, and feeds the defect coordinates back to the headstock control unit in real time. Based on this data, the headstock adjusts its movement trajectory along the carriage rails and stringer rails, ensuring the cutting path automatically avoids defective areas.

[0015] Specifically, this invention achieves synchronous linkage between the detection and cutting processes, avoiding the separation of processes in the traditional "detect first, then cut" approach, and significantly improving cutting accuracy and material utilization.

[0016] In a preferred embodiment, the pressing assembly includes a positioning seat, a sliding guide sleeve, a shaft slide rod, and multiple pressure rollers. A spring-loaded rotating box is mounted on the surface of the positioning seat to drive the sliding guide sleeve and shaft slide rod to rotate or elastically deflect, thereby applying flexible downward pressure to the corrugated paper surface by the pressure rollers. The sliding guide sleeve has an arc-shaped plate structure, and its inner wall slidably abuts against a toothed ring, enabling adaptive clamping adjustment during operation.

[0017] In a preferred example, the shaft slide rod is provided with an excitation coil arranged in a straight line, and the slide sleeve is embedded with a corresponding permanent magnet. The two drive the pressure roller to move laterally through magnetic attraction or repulsion, thereby adjusting the pressure roller spacing.

[0018] In a preferred embodiment, the feeding assembly includes a synchronous drive box, multiple rotating shafts, and conveyor bars. Each rotating shaft has a crank wheel on its surface, and the multiple rotating shafts are arranged in parallel along the synchronous drive box and driven to rotate synchronously by it.

[0019] In a preferred example, the crank wheel consists of several eccentric discs, the centers of which are offset from the axis of rotation and evenly distributed along the circumference. A conveyor bar is rotatably fitted onto the outer circumference of the crank wheel, and a rubber strip is fixedly mounted on its top surface to increase friction with the bottom surface of the cardboard.

[0020] Specifically, when the synchronous transmission box drives the rotating shaft to rotate, the crank wheel generates a periodic eccentric motion, which drives the conveyor strips to move back and forth alternately, realizing the peristaltic conveying of corrugated paper. This peristaltic feeding structure can pause the conveying at the moment of visual inspection, and shoot synchronously with the shutter frequency of the industrial camera, avoiding the ghosting phenomenon and improving the detection accuracy and feeding stability.

[0021] The multi-layer corrugated cardboard box manufacturing process of the present invention includes the following core steps:

[0022] Visual inspection: The entire surface of the corrugated paper is scanned and images are acquired using upper and lower scanners;

[0023] Defect identification: The AI ​​detection module identifies defects and generates coordinate data;

[0024] Path correction: The headstock receives the defect coordinates and corrects the cutting path to ensure that the cutting trajectory avoids the defect area;

[0025] Cutting execution: The wire saw or laser cutting head performs precise cutting according to the corrected path;

[0026] Smooth output: The feeding assembly performs peristaltic conveying, and the pressing assembly presses down and limits the paperboard during this process.

[0027] Specifically, this invention achieves fully closed-loop intelligent control from detection and decision-making to execution, significantly improving the automation of the production line and product consistency.

[0028] The beneficial effects achieved by this invention are as follows:

[0029] 1. In this invention, by setting a traveling slide rail and a gantry slide rail on the cutting machine table, and arranging an upper scanner and a lower scanner group at the bottom of the machine head and the table surface respectively, a stereo vision inspection system is formed, which realizes real-time detection and image acquisition of the surface of multi-layer corrugated paper; combined with the AI ​​detection module for automatic identification of surface defects and correction of cutting path, the cutting process can actively avoid defective areas such as creases and damage, thereby significantly improving the yield and cutting accuracy of carton products.

[0030] 2. In this invention, by adopting a crank-driven feeding assembly structure, the reciprocating motion of the conveying strip is realized by using an eccentric turntable, and rubber strips are set on the surface of the strip to enhance friction, thereby realizing the smooth conveying and synchronous feeding of corrugated paper, avoiding slippage and deviation problems, and ensuring the continuity and high-precision connection of the whole machine operation.

[0031] 3. In this invention, the feeding component adopts a crank-driven peristaltic conveying mechanism to replace the traditional continuous rotating conveyor belt structure, which can realize intermittent conveying and synchronous control, so that the corrugated paper completes accurate visual imaging at the moment of each conveying movement stop, avoiding the problem of camera shooting ghosting, thereby improving the recognition accuracy of visual inspection and cutting synchronization.

[0045] 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 and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0046] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0047] The following describes, with reference to the accompanying drawings, some embodiments of a multi-layer corrugated cardboard box production equipment and its process.

[0048] Combination Figures 1-9 As shown, the present invention provides a multi-layer corrugated carton production equipment, including a cutting machine 100, a machine head base 130, a pressing assembly 200, and a feeding assembly 300.

[0049] The cutting machine table 100 serves as the supporting base of the device, and its surface is equipped with a traveling slide rail 110 and a gantry slide rail 120, which are used to drive the machine head base 130 to move precisely in the transverse and longitudinal directions, respectively. The traveling slide rail 110 and the gantry slide rail 120 are arranged perpendicular to each other, with the traveling slide rail 110 fixedly installed on the surface of the cutting machine table 100, and the two ends of the gantry slide rail 120 slidably installed on the surface of the traveling slide rail 110. Both adopt a lead screw drive structure to achieve smooth reciprocating motion and high-precision positioning of the machine head base 130.

[0050] In this embodiment, a plurality of lower scanner groups 140 arranged in a horizontal array are embedded in the surface of the cutting machine table 100, and an upper scanner 150 is fixedly installed on the bottom surface of the machine head base 130. The upper scanner can adopt an industrial camera structure to acquire images of the corrugated paper surface and perform real-time comparative analysis. The upper and lower scanners form corresponding detection channels for full-frame stereoscopic visual inspection of the surface of multi-layer corrugated paper.

[0051] In this embodiment, the headstock 130 is used to mount a corrugated cardboard box cutting head, which can be either a wire saw cutting head or a laser cutting head. The output terminals of the upper scanner 150 and the lower scanner group 140 are electrically connected to a vision inspection system, which is used to acquire two-dimensional and three-dimensional images of the corrugated cardboard surface and perform real-time comparative analysis.

[0052] The vision inspection system integrates an AI inspection module, which uses deep learning algorithms to identify features on the corrugated paper surface. This module can automatically identify and locate defective areas such as creases, dents, tears, and splicing errors. The inspection system feeds back the identified defect coordinates to the 130 control unit of the headstock in real time to automatically correct the cutting path, ensuring the cutting trajectory avoids defective areas. This guarantees smooth edges, accurate dimensions, and minimizes waste in the finished cardboard.

[0053] In this embodiment, the pressing assembly 200 includes a positioning seat 210, a sliding guide sleeve 220, a shaft slide rod 230, and multiple pressure rollers 240. A spring-loaded rotating box 221 is provided on the surface of the positioning seat 210 to drive the sliding guide sleeve 220 and the shaft slide rod 230 to rotate and elastically deflect. Several pressure rollers 240 are slidably mounted on the outer surface of the shaft slide rod 230, and each pressure roller 240 is connected to the shaft slide rod 230 via a sliding sleeve seat 241. A sliding toothed ring 242 is fixedly mounted on one side of the sliding sleeve seat 241. The surface of the sliding toothed ring 242 is provided with several teeth, and it slidably abuts against the inner side of the sliding guide sleeve 220.

[0054] The guide sleeve 220 has an arc-shaped plate structure. The spring-driven rotating box 221 drives the guide sleeve 220 and the shaft slide rod 230 to produce elastic deflection, so that the pressure roller 240 forms a variable elastic pressing contact with the corrugated paper surface, thereby realizing adaptive adjustment of the pressing force during operation and preventing the indentation from being too deep or the paperboard from slipping.

[0055] In this embodiment, an excitation coil 231 arranged in a straight line is provided on the inner side of the shaft slide 230, and a permanent magnet 243 arranged opposite to the excitation coil 231 is embedded on the inner side of the sliding sleeve 241. When the excitation coil 231 is energized, the magnetic attraction or repulsion between the excitation coil 231 and the permanent magnet 243 drives the pressure roller 240 and the sliding sleeve 241 to move laterally along the shaft slide 230, thereby adjusting the spacing or position of the pressure roller 240. This structure allows the pressing assembly to automatically calibrate the pressing position for paperboard of different widths, thereby ensuring the flatness and stability of multi-layer corrugated paper during conveying and cutting.

[0056] In this embodiment, the feeding assembly 300 includes a synchronous transmission box 310, multiple rotating shafts 320, and conveying strips 330. A crank wheel 321 is fixedly connected to the outer surface of each rotating shaft 320, and the conveying strips 330 are rotatably sleeved on the surface of the crank wheel 321. Several rotating shafts 320 are arranged parallel to each other along the surface of the synchronous transmission box 310 and are driven to rotate synchronously by the synchronous transmission box 310.

[0057] The crank wheel 321 consists of several eccentric turntables connected in sequence. The center of each turntable is offset from the axis of the rotating shaft 320 and is evenly distributed along the circumference. When rotating, the crank wheel 321 drives the conveyor bar 330 to make alternating reciprocating linear motion through periodic eccentric motion, so as to realize the continuous feeding of corrugated paper.

[0058] The conveyor bar 330 is a straight plate structure with several round holes on its surface and is rotatably fitted onto the surface of the crank wheel 321. A rubber strip 331 is fixedly installed on the top surface of the conveyor bar 330. The rubber strip 331 can increase the friction with the bottom surface of the corrugated paper, prevent the paperboard from slipping during the conveying process, and improve the stability and accuracy of the feeding.

[0059] The process steps in the production of multi-layer corrugated cardboard boxes according to the present invention are as follows:

[0060] 1. Visual inspection steps: The surface of the corrugated paper is scanned in full width by the upper scanner 150 at the bottom of the headstock 130 and the lower scanner group 140 on the cutting table 100 to obtain the surface image information of the paperboard.

[0061] 2. Defect Identification Steps: The visual inspection system inputs the acquired images into the AI ​​detection module. The AI ​​detection module automatically identifies defects such as creases, dents, damage, and splicing errors based on deep learning algorithms, and generates defect coordinates.

[0062] 3. Path correction steps: The visual inspection system feeds back the defect coordinates to the headstock 130 in real time. The headstock 130 adjusts the movement trajectory along the carriage slide rail 110 and the gantry slide rail 120 to correct the cutting path so that the cutting trajectory avoids the defect area.

[0063] 4. Cutting execution steps: The wire saw or laser cutting head on the headstock 130 performs the cutting operation according to the corrected path to ensure smooth cut edges and accurate shape;

[0064] 5. Finished product output steps: The feeding component 300 drives the conveying strip 330 to achieve stable conveying of corrugated paper. The pressing component 200 elastically presses and positions the surface of the corrugated paper during the conveying process to ensure the stability of the paperboard posture.

[0065] Through the aforementioned structural design and process flow, this invention enables automatic detection, intelligent defect avoidance, precise cutting, and stable conveying of multi-layer corrugated paper. The vision inspection system, combined with AI algorithms, achieves real-time defect identification and path optimization; the pressing component provides adaptive flexible clamping; and the feeding component ensures continuous and stable conveying. This equipment significantly improves the automation level and product qualification rate of corrugated carton production lines, possessing high precision, high stability, and significant industrial application value.

[0066] Working principle and usage process of this invention:

[0067] The present invention provides a multi-layer corrugated cardboard box production equipment, which realizes automatic detection, intelligent cutting and stable conveying processing of multi-layer corrugated paper through the coordinated operation of the cutting machine 100, the machine head base 130, the pressing component 200 and the feeding component 300.

[0068] During operation, the cutting table 100 serves as the support platform for the entire device. Its surface features a traveling rail 110 and a gantry rail 120 that are perpendicular to each other, used to drive the headstock 130 to move precisely in the horizontal and vertical directions. An upper scanner 150 is fixedly mounted at the bottom of the headstock 130, while the lower scanner array 140 distributed across the surface of the cutting table 100, together with the upper scanner 150, forms a stereoscopic vision inspection system to perform full-width scanning and image acquisition of the corrugated paper surface.

[0069] After scanning, the visual inspection system inputs the collected image data into the AI ​​detection module. The AI ​​detection module uses deep learning algorithms to analyze the image information, automatically identifying defective areas such as creases, dents, tears, and splicing errors on the corrugated paper surface, and generating corresponding defect coordinate data. The detection system feeds back the defect coordinates to the control module of the headstock 130 in real time. Based on this, the headstock 130 adjusts its movement path along the carriage slide rail 110 and the girder slide rail 120, automatically correcting the cutting trajectory to avoid defective areas, thereby preventing defective parts from entering the finished product and improving the carton forming accuracy and finished product qualification rate.

[0070] During the cutting operation, the wire saw or laser cutting head mounted on the headstock 130 performs high-speed cutting along the corrected path under the command of the control system. During the cutting process, the pressure assembly 200 plays a stabilizing and positioning role. The pressure assembly 200 includes a positioning seat 210, a sliding guide sleeve 220, a shaft slide rod 230, and a pressure roller 240. The pressure roller 240 is sleeved on the shaft slide rod 230 via a sliding sleeve seat 241, and the sliding sleeve seat 241 and the sliding guide sleeve 220 are slidably engaged via a sliding tooth ring 242. When the spring-driven cylinder 221 causes the shaft slide rod 230 and the sliding guide sleeve 220 to elastically deflect, the pressure roller 240 presses down on the corrugated paper surface in a flexible manner, achieving adaptive clamping of the cardboard. At the same time, the excitation coil 231 in the slide bar 230 and the permanent magnet 243 in the slide sleeve seat 241 form a magnetic attraction or repulsion driving force, which enables the pressure roller 240 to make slight lateral adjustments to match cardboard of different specifications or thicknesses, ensuring uniform pressing and no damage to the corrugated structure.

[0071] In a compressed and fixed state, the feeding assembly 300 is responsible for the stable conveying of the cardboard. The feeding assembly 300 includes a synchronous drive box 310, a rotating shaft 320, and a conveyor bar 330. A crank wheel 321 is mounted on the surface of the rotating shaft 320, and the conveyor bar 330 is sleeved on the surface of the crank wheel 321. When the synchronous drive box 310 drives each rotating shaft 320 to rotate synchronously, the crank wheel 321 drives the conveyor bar 330 to form a periodic reciprocating motion, thereby realizing the continuous pushing of the corrugated paper. The rubber strip 331 provided on the surface of the conveyor bar 330 provides high friction to prevent the cardboard from slipping during conveying and ensure smooth conveying.

[0072] In summary, the workflow of this invention is as follows:

[0073] The feeding assembly 300 conveys the multi-layer corrugated paper to the detection area of ​​the cutting machine 100; the upper scanner 150 and the lower scanner group 140 complete visual inspection and transmit image data; the AI ​​detection module identifies defects and feeds back correction signals to the headstock 130; the headstock 130 adjusts the cutting path and drives the cutting head to perform intelligent cutting; the pressing assembly 200 simultaneously performs pressing and posture stabilization; the cut cardboard is output to the back-end process through the feeding assembly 300.

[0074] Through the above coordination, this equipment can achieve real-time detection, defect avoidance and intelligent cutting of multi-layer corrugated paper, thereby realizing the automation, high precision and high yield output of the carton production process, significantly improving production efficiency and finished product quality.
