Description

Technical Field

[0001] This invention relates to the field of cardboard box production technology, and in particular to a cardboard board punching equipment and its control method. Background Technology

[0002] In the current era of rapid development in the packaging industry, cardboard boxes serve as the core carrier for product transportation and storage. Their production efficiency and quality directly affect the overall efficiency of the supply chain. The die-cutting process, as a key link in cardboard board processing, directly determines the forming accuracy, appearance quality, and subsequent processing efficiency of cardboard boxes. The die-cutting process involves cutting cardboard boards with a cutting knife to obtain cardboard board blanks of the required size and shape.

[0003] Existing cardboard die-cutting equipment includes a worktable, a moving table, a clamping mechanism, a moving mechanism, a lifting mechanism, and a cutting mechanism. During operation, the cardboard to be processed is first placed on the moving table. Then, the clamping mechanism clamps and secures the cardboard to prevent displacement during die-cutting. Next, the moving mechanism moves the moving table horizontally, precisely conveying the clamped cardboard to the area below the cutting mechanism. Then, the lifting mechanism moves the cutting mechanism vertically, bringing it into contact with the cardboard surface. Finally, the cutting mechanism punches the clamped cardboard, completing the cutting process.

[0004] In the above structure, after the cardboard is punched, the cutting mechanism will produce loose fibers and burrs at the cut, and tiny gaps will be formed inside the cut. This will make the cut very easy to deform. This problem will directly lead to the inability to successfully assemble into a qualified box, thus greatly reducing the cardboard processing quality and the finished product qualification rate. Summary of the Invention

[0005] To prevent deformation at the cut edges of cardboard boxes and improve the processing quality of cardboard boxes, this invention provides a cardboard box punching device.

[0006] In a first aspect, the present invention provides a cardboard punching device, which adopts the following technical solution: A cardboard board punching machine includes a worktable, a movable table slidably mounted on the worktable, a moving mechanism for driving the movable table to move, a clamping mechanism for clamping and fixing the cardboard board to be processed, a cutting mechanism for cutting the cardboard board to be processed, and a lifting mechanism for driving the cutting mechanism to rise and fall. It also includes a driving mechanism for driving the cutting mechanism to move horizontally and a curing mechanism for driving the cutting mechanism to work and curing the cut edge of the cardboard board. The curing mechanism includes a grinding roller for grinding the cut, a starting component mounted on the cutting mechanism for driving the grinding roller to work synchronously with the cutting mechanism, a heat-generating block for contacting the grinding roller and the cutting mechanism and generating heat when they work, a connecting component for driving the heat-generating block to contact the grinding roller and the cutting mechanism, and an air supply component mounted on the driving mechanism. The air supply assembly is used to deliver air to the cut and generate hot air through the heat-generating block to solidify the cut.

[0007] By adopting the above technical solution, the driving mechanism and the curing mechanism can achieve simultaneous cutting and curing of the cut. During cutting, burrs are removed by the grinding roller, the heat-generating block generates heat through friction, and the air conveying component forms hot air for drying and shaping. This prevents the carton board from becoming loose and deformed, thereby improving the carton forming accuracy and the finished product qualification rate.

[0008] Optionally, a gantry frame is installed on the workbench, and a movable frame is slidably installed inside the gantry frame; The driving mechanism includes a first threaded rod rotatably mounted in the movable frame, a movable plate threadedly connected to the first threaded rod and slidably mounted on the movable frame, and a first motor mounted on the movable frame for driving the first threaded rod to rotate. The air supply assembly includes an air supply box mounted on the movable frame and slidably mounted on the gantry, a second threaded rod rotatably mounted on the air supply box, a piston plate threadedly connected to the second threaded rod and slidably mounted inside the air supply box, an air supply pipe communicating with the air supply box and supplying air, and a first synchronization structure for synchronously driving the second threaded rod to rotate when the first threaded rod rotates.

[0009] By adopting the above technical solution, the first motor drives the first threaded rod to drive the cutting mechanism to move horizontally, thereby achieving precise feeding of the cutting mechanism. At the same time, the first synchronization structure enables the cutting movement and air supply to be linked synchronously. When the first threaded rod rotates, it synchronously drives the air box, piston plate and air supply pipe to work to achieve air supply, ensuring that hot air continuously and stably acts on the cut and improving the consistency of curing.

[0010] Optionally, the cutting mechanism includes a protective frame mounted on the movable plate, a cutting roller rotatably mounted within the protective frame, and a cutting blade mounted on the cutting roller for cutting the cardboard. The starting assembly includes a starting rod rotatably mounted on the protective frame and on the grinding roller, a worm gear section mounted on the protective frame, a worm wheel meshing with the worm gear section and driving the starting rod to rotate, a second synchronization structure for driving the worm gear section to rotate synchronously with the cutting roller, and a second motor mounted on the protective frame for driving the worm gear section to rotate.

[0011] By adopting the above technical solution, the second motor, through the worm gear and the second synchronization structure, enables the cutting blade and the grinding roller to rotate synchronously, thereby allowing cutting and grinding to be carried out simultaneously, simplifying the transmission structure, improving processing efficiency, and ensuring that burrs on the cut are removed in time, thus improving the flatness of the cut.

[0012] Optionally, when the lifting mechanism drives the cutting mechanism to approach the cardboard, it will simultaneously drive the connecting assembly to work. The connecting assembly includes a connecting strip slidably mounted on the protective frame and mounted on the heat-generating block, a first limiting telescopic column mounted on the protective frame, a driving block mounted on the first limiting telescopic column, a driving rod hinged between the driving block and the connecting strip, and an ejector block mounted on the gantry and used to drive the driving block to move. The drive block has an inclined surface, and the ejector block has an ejector surface that matches the inclined surface; there are two sets of connecting bars, drive rods, and first limiting telescopic columns, and a compression spring connects the two connecting bars, which drives the two connecting bars to always tend to move away from each other.

[0013] By adopting the above technical solution, when the lifting mechanism descends, the push block presses against the drive block, causing the drive block to move. When the drive block moves, it pushes the connecting strip to automatically contact the cutting blade and the grinding roller with the heat-generating block, thereby causing the heat-generating block to generate a large amount of heat. When the lifting mechanism rises, the push block and the drive block no longer press against each other. At this time, the compression spring drives the connecting strip to move, so that the heat-generating block no longer contacts the cutting blade and the grinding roller, thus achieving the effect of heating upon descent and cooling upon detachment upon ascent.

[0014] Optionally, the workbench is provided with a waste collection component for cooperating with the air conveying component to collect the waste debris blown up by the air conveying component; The waste collection assembly includes a fixed base mounted on the gantry, an extraction pump mounted on the fixed base for collecting waste, a suction pipe connected to the dust inlet of the extraction pump, a suction hood installed at the inlet of the suction pipe, a dust discharge pipe connected to the outlet of the extraction pump, and a waste collection box mounted on the workbench for collecting the waste discharged from the dust discharge pipe.

[0015] By adopting the above technical solution, the extraction pump and dust hood collect the paper scraps and dust raised by the hot air into the waste collection box, avoiding dust pollution and secondary adhesion of paperboard; at the same time, the airflow-assisted cuts are quickly cooled and shaped, further reducing the risk of deformation.

[0016] Optionally, a movable frame is mounted on the movable platform, the movable frame is slidably mounted on the worktable, and the clamping mechanism is mounted on the movable frame; The clamping mechanism includes two third threaded rods rotatably mounted on the movable frame, a threaded cylinder threadedly connected to the third threaded rods, a guide plate mounted on the threaded cylinder and slidably mounted on the movable frame, a clamping frame mounted on the top of the threaded cylinder, a clamping block mounted inside the clamping frame for clamping and fixing the carton board, a third synchronization structure for driving the two third threaded rods to rotate synchronously, and a third motor mounted on the movable frame for driving one of the third threaded rods to rotate.

[0017] By adopting the above technical solution, the third motor, in conjunction with the third synchronous structure, drives the two third threaded rods to rotate synchronously, thereby driving the clamping block connected to it to press down, so that the clamping block clamps the cardboard to be processed, preventing the cardboard from shifting during punching and ensuring the cutting dimension accuracy.

[0018] Optionally, the lifting mechanism includes a second limiting telescopic column installed between the gantry and the movable frame, and a hydraulic cylinder installed on the gantry and used to drive the movable frame to lift. The moving mechanism includes an arc-shaped block mounted on the workbench, a fourth threaded rod rotatably mounted on the arc-shaped block and threadedly connected to the moving frame, and a fourth motor mounted on the arc-shaped block for driving the fourth threaded rod to rotate.

[0019] By adopting the above technical solution, the hydraulic cylinder and the second limit telescopic column ensure that the vertical lifting of the cutting mechanism is stable and without sway, so that the cutting mechanism can accurately cut the cardboard. The fourth motor and the fourth threaded rod drive the moving table to move horizontally, thereby accurately transporting the cardboard clamped on the moving table to the bottom of the cutting mechanism.

[0020] Secondly, this application provides a control method for a cardboard punching equipment, which adopts the following technical solution: A control method for a cardboard board punching machine, applied to a cardboard board punching machine, further comprising: Acquire images of the workbench surface; Based on the preset placement position, determine whether the cardboard to be processed is placed in the correct position from the image of the workbench surface; When the cardboard is placed in place, the lifting mechanism drives the cutting mechanism to approach the cardboard at a preset pressing height and pressing speed. During the downward movement of the cutting mechanism, the heat-generating block is driven to contact the cutting blade and the grinding roller with a preset initial contact pressure, while the air supply component is controlled to deliver air with a preset initial air supply power. During the operation of the cutting mechanism, the operating current and operating resistance of the cutting blade are collected; The current deviation value is obtained based on the operating current of the cutting blade and the preset standard drying condition current. The resistance deviation value is obtained based on the running resistance of the cutting blade and the preset standard drying condition resistance. The moisture level of the cardboard is determined based on the current deviation value and the resistance deviation value, and the moisture level is verified. When the cardboard is damp, the initial contact pressure is corrected by a preset enhanced contact pressure to increase the temperature of the heat-generating block, the initial air supply power is corrected by a preset enhanced air supply power to increase the hot air output power of the air supply component, and the cutting mechanism is controlled by a preset extended cutting speed to extend the hot air curing time of the cut.

[0021] By adopting the above technical solution, the cardboard is confirmed to be in place by image recognition. Then, the lifting mechanism is controlled to work, the cutting mechanism is controlled to press down, and the curing mechanism is controlled to heat and blow air by contact. At the same time, the current and resistance are monitored in real time to determine the humidity of the cardboard, and the heat generation pressure, hot air power and cutting speed are automatically adjusted to adapt to dry or humid conditions, so as to ensure that the cardboard can be stably cured without deformation under different humidity conditions.

[0022] Optional methods for verifying moisture conditions include: Capture images of the cut edges of the cardboard box. Fiber looseness characteristics were obtained from the incision forming images; Determine whether the fiber looseness exceeds the preset looseness threshold; The moisture test passes when the fiber looseness exceeds the looseness threshold. If the fiber looseness does not exceed the looseness threshold, the cardboard is not damp, and the machine should be stopped for inspection.

[0023] By adopting the above technical solution, the fiber looseness is analyzed through cut images, and the humidity judgment is verified a second time to avoid sensor misjudgment leading to parameter misadjustment, thereby improving the reliability of equipment operation and processing stability.

[0024] Optional solutions for when cardboard is damp include: Collect the initial position information, real-time position information, and hot air distribution information of the cutting mechanism in the cutting area; Based on the initial position information, target waste collection components that are close to the cutting mechanism and non-target waste collection components that are far from the cutting mechanism are matched; Match the hot air coverage range of the incision based on hot air distribution information; The adsorption range of the target waste collection component is determined by combining the coverage range of the hot air at the cut, real-time location information, and the preset location of the target waste collection component. The adsorption force of the target waste collection component is matched based on the adsorption range; The cutting direction of the cutting mechanism is determined based on the initial position information and the real-time position information; The target waste collection component is controlled to use suction force to draw air from the cutting mechanism to remove the hot air from the cut in the opposite direction of the cutting direction, and the non-target waste collection component is controlled to shut off.

[0025] By adopting the above technical solution, the corresponding waste collection components are dynamically activated according to the cutting position and hot air range, and hot air and waste are sucked away in the opposite direction of cutting, thereby enhancing the drying effect, reducing heat loss, and improving the processing quality of damp cardboard.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The cutting and curing of the cut are carried out simultaneously through the drive mechanism and the curing mechanism. During the cutting process, the burrs are removed by the grinding roller, the heat generation block generates heat through friction, and the air conveying component forms hot air to dry and shape the carton. This prevents the carton board from becoming loose and deformed from the source, and improves the carton forming accuracy and the finished product qualification rate. 2. When the lifting mechanism descends, the push block presses against the drive block, causing the drive block to move. As the drive block moves, it pushes the connecting strip to automatically contact the cutting blade and grinding roller with the heat-generating block, thereby generating a large amount of heat in the heat-generating block. When the lifting mechanism rises, the push block and drive block no longer press against each other. At this time, the compression spring drives the connecting strip to move, so that the heat-generating block no longer contacts the cutting blade and grinding roller, thus achieving the effect of heating upon descent and cooling upon detachment upon ascent. 3. The first motor drives the first threaded rod to drive the cutting mechanism to move horizontally, realizing the precise feeding of the cutting mechanism. At the same time, the first synchronization structure enables the cutting movement and air supply to be linked synchronously. When the first threaded rod rotates, it synchronously drives the air box, piston plate and air supply pipe to work to realize air supply, ensuring that hot air continuously and stably acts on the cut and improving the consistency of curing.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] This application discloses a cardboard punching device.

[0031] Reference Figure 1 as well as Figure 2 A cardboard punching device includes a worktable 1, a moving table 2, a moving mechanism 4, a clamping mechanism 3, a cutting mechanism 7, a lifting mechanism 5, a driving mechanism 6, and a curing mechanism 8.

[0032] A gantry frame 11 is fixedly installed on the top of the workbench 1. A movable frame 21 is fixedly installed on the side of the movable table 2 near the workbench 1. A movable hole 12 is provided on the workbench 1, and the movable frame 21 is slidably installed in the movable hole 12. A moving mechanism 4 is installed on the workbench 1 and is used to drive the movable frame 21 to move horizontally. A clamping mechanism 3 is fixedly installed on the movable frame 21 and is used to clamp and fix the cardboard to be processed. A lifting mechanism 5 is installed on the gantry frame 11 and is used to drive the cutting mechanism 7 to move up and down. A drive mechanism 6 is installed on the lifting mechanism 5 and is used to drive the cutting mechanism 7 to move horizontally. The cutting mechanism 7 is installed on the drive mechanism 6 and is used to cut the cardboard to be processed. A curing mechanism 8 is used to cure the cut edge of the cardboard when the cutting mechanism 7 is working.

[0033] During operation, the cardboard to be processed is placed above the moving table 2, and the cardboard is positioned and clamped by the clamping mechanism 3. Then, the moving mechanism 4 drives the moving frame 21 to move horizontally along the moving hole 12 of the worktable 1, thereby moving the moving table 2 and the clamped cardboard to the cutting station. Subsequently, the lifting mechanism 5 drives the cutting mechanism 7 to descend along the gantry 11 to the preset cutting height. Then, the curing mechanism 8 is activated, which provides working power to the cutting mechanism 7 and cures the cut position of the cardboard, reducing burrs, preventing delamination and cracking of the cardboard, and improving the cutting quality and structural strength. Finally, the driving mechanism 6 drives the cutting mechanism 7 to feed horizontally, so that the cutting mechanism 7 can perform punching and cutting operations on the cardboard below.

[0034] Reference Figure 3 The clamping mechanism 3 includes a third threaded rod 31, a threaded cylinder 32, a guide plate 33, a clamping frame 34, a clamping block 35, and a third motor 36.

[0035] The third threaded rod 31 is rotatably mounted on the movable frame 21, and the threaded cylinder 32 is threadedly connected to the third threaded rod 31. A guide plate 33 is fixedly mounted on the outside of the threaded cylinder 32, and guide blocks 37 are fixedly mounted on both sides of the guide plate 33. A guide groove 38 is provided on the inner side of the movable frame 21, and the guide blocks 37 are slidably mounted in the guide groove 38 to guide the lifting and lowering of the threaded cylinder 32, making the lifting and lowering of the threaded cylinder 32 more stable. A clamping frame 34 is fixedly mounted on the end of the threaded cylinder 32 away from the third threaded rod 31, and a clamping block 35 is fixedly mounted on the inner side of the clamping frame 34 to clamp and fix the cardboard. The third motor 36 is fixedly mounted on the movable frame 21, and the output end of the third motor 36 is fixedly connected to the third threaded rod 31 via a coupling.

[0036] In this embodiment, the clamping mechanism 3 further includes a third synchronization structure 39. The third synchronization structure 39 includes a third synchronization pulley 391 and a third synchronization belt 392.

[0037] The number of third threaded rods 31, threaded cylinders 32, guide plates 33, clamping frames 34, clamping blocks 35, and third synchronous pulleys 391 are all two and symmetrically arranged on the moving platform 2. The two third synchronous pulleys 391 are fixedly installed on the corresponding third threaded rods 31, and the third synchronous belt 392 is sleeved on the outside of the two third synchronous pulleys 391, so that when the third motor 36 drives one of the third threaded rods 31 to rotate, the two third threaded rods 31 are driven to rotate synchronously through the two third synchronous pulleys 391 and the third synchronous belt 392.

[0038] Reference Figure 3 The moving mechanism 4 includes an arc-shaped block 41, a fourth threaded rod 42, and a fourth motor 43. There are two arc-shaped blocks 41. The fourth threaded rod 42 is rotatably mounted between the two arc-shaped blocks 41, and the moving frame 21 is threadedly connected to the fourth threaded rod 42. The fourth motor 43 is fixedly mounted on one of the arc-shaped blocks 41, and the output end of the fourth motor 43 is fixedly connected to the fourth threaded rod 42 via a coupling.

[0039] During operation, the cardboard to be processed is placed on the moving table 2. Then, the third motor 36 is started to drive one of the third threaded rods 31 to rotate. Subsequently, under the transmission action of the third synchronous pulley 391 and the third synchronous belt 392, the two third threaded rods 31 rotate synchronously, thereby driving the threaded cylinder 32 connected to it to move vertically downward under the limiting guidance of the guide plate 33, the guide block 37 and the guide groove 38. This drives the pressing frame 34 and the clamping block 35 to move vertically downward, so that the clamping block 35 presses and fixes the cardboard to be processed on the moving table 2, thereby completing the positioning and clamping of the cardboard to be processed.

[0040] Then, the fourth motor 43 is started to drive the fourth threaded rod 42 to rotate. When the fourth threaded rod 42 rotates, it drives the movable frame 21 connected to it to move horizontally along the movable hole 12 of the worktable 1, thereby driving the movable table 2 and the clamped carton board to move horizontally along the movable hole 12, so as to transport the clamped carton board to the bottom of the cutting mechanism 7, so as to facilitate the subsequent cutting mechanism 7 to punch the carton board.

[0041] Reference Figure 4 The gantry frame 11 has two sliding holes 13, and each sliding hole 13 has a sliding strip 14 slidably connected to it. The same moving frame 16 is fixedly installed at the ends of the two moving strips 14 that are close to each other. Two limiting blocks 15 are fixedly installed on the outer sides of the two moving strips 14. The ends of the two limiting blocks 15 that are close to each other abut against the gantry frame 11, thereby limiting and guiding the movement of the moving frame 16, making the movement of the moving frame 16 more stable.

[0042] Reference Figure 4 The lifting mechanism 5 includes a second limiting telescopic column 51 and a hydraulic cylinder 52. The hydraulic cylinder 52 is fixedly installed on the top inner side of the gantry frame 11, and the output end of the hydraulic cylinder 52 is fixedly connected to the movable frame 16. One end of the second limiting telescopic column 51 is fixedly installed on the top inner side of the gantry frame 11, and the other end of the second limiting telescopic column 51 is fixedly installed on the top of the movable frame 16, thereby limiting and guiding the vertical movement of the movable frame 16 and preventing the movable frame 16 from deviating during movement.

[0043] Reference Figure 4 The drive mechanism 6 includes a first threaded rod 61, a movable plate 62, and a first motor 63. The first threaded rod 61 is rotatably mounted inside the movable frame 16, and the movable plate 62 is threadedly connected to the first threaded rod 61. A movable groove 64 is provided on the inner top side of the movable frame 16, and the movable plate 62 is slidably mounted in the movable groove 64. A support base 65 is fixedly mounted on one of the movable bars 14, and the first motor 63 is fixedly mounted on the support base 65. The output end of the first motor 63 is fixedly connected to one end of the first threaded rod 61 through a coupling.

[0044] Reference Figure 5 The cutting mechanism 7 includes a protective frame 71, a cutting roller 72, and a cutting blade 73. The protective frame 71 is fixedly mounted on the movable plate 62, the cutting roller 72 passes through the protective frame 71 and is rotatably mounted in the protective frame 71, and the cutting blade 73 is fixedly mounted on the cutting roller 72.

[0045] Reference Figure 2 as well as Figure 5 The curing mechanism 8 includes a grinding roller 81, a starting component 83, a heat generating block 82, a connecting component 84, and an air conveying component 85.

[0046] The grinding roller 81 is used to grind the cut edge when the cutting mechanism 7 cuts the carton board, thereby removing burrs and heating the cut edge during grinding. The starting assembly 83 drives the grinding roller 81 to work synchronously with the cutting mechanism 7. The heating block 82 is used to contact the grinding roller 81 and the cutting mechanism 7 to generate heat during operation. The connecting assembly 84 drives the heating block 82 to contact the grinding roller 81 and the cutting mechanism 7. The air supply assembly 85 delivers air to the cut edge and forms hot air through the heating block 82 to cure the cut edge. The lifting assembly drives the connecting assembly 84 to work synchronously when it drives the cutting mechanism 7 close to the carton board.

[0047] Reference Figure 6 The starting assembly 83 includes a starting rod 831, a worm gear section 832, a worm wheel 833, a second synchronization structure 835, and a second motor 834. The second synchronization structure 835 includes two second synchronization pulleys 8351 and a second synchronization belt 8352.

[0048] The starting rod 831 passes through the protective frame 71 and rotates within the protective frame 71. The bottom end of the starting rod 831 is fixedly installed on the top end of the grinding roller 81. Two limiting rings 836 are fixedly installed on the outer side of the starting rod 831, with the sides of the two limiting rings 836 abutting against the inner and outer sides of the top of the protective frame 71, respectively. Two fixing blocks 837 are fixedly installed on the protective frame 71, and the worm gear section 832 is rotatably installed between the two fixing blocks 837. A support frame 838 is fixedly installed on the protective frame 71, and a second motor 834 is fixedly installed on the support frame 838. The output end of the second motor 834 is fixedly connected to one end of the worm gear section 832 via a coupling. The worm wheel 833 meshes with the worm gear section 832 and is fixedly installed on the starting rod 831. Two second synchronous pulleys 8351 are fixedly mounted on the worm section 832 and the cutting roller 72 respectively. The second synchronous belt 8352 is driven sleeved on the outside of the two second synchronous pulleys 8351. Thus, when the second motor 834 drives the worm section 832 to rotate, the cutting roller 72 is driven to rotate synchronously through the cooperation of the second synchronous pulleys 8351 and the second synchronous belt 8352, which in turn drives the grinding roller 81 and the cutting blade 73 to rotate synchronously, so that the two work synchronously.

[0049] When the lifting mechanism 5 drives the cutting mechanism 7 to approach the carton board, it will simultaneously drive the connecting component 84 to work.

[0050] Reference Figure 5 The connecting component 84 includes a connecting bar 841, a first limiting telescopic column 842, a driving block 843, a driving rod 844, and an ejector block 845.

[0051] In this embodiment, the number of connecting strips 841, first limiting telescopic columns 842, driving rods 844, and heat-generating blocks 82 are all in two sets and symmetrically arranged on the protective frame 71. Two connecting holes 846 are provided on the protective frame 71. The two connecting strips 841 are slidably installed in the corresponding connecting holes 846, and the two sets of heat-generating blocks 82 are fixedly installed inside the corresponding connecting strips 841. One end of each of the two first limiting telescopic columns 842 is fixedly installed on the protective frame 71, and the other end is fixedly installed on the driving block 843. This allows the driving block 843 to be limited and guided by the two first limiting telescopic columns 842 when it moves, preventing deviation during movement. One end of each of the two driving rods 844 is hinged to the driving block 843, and the other end is hinged to the corresponding connecting strip 841. A single compression spring 847 is fixedly connected between the two connecting strips 841, and the compression spring 847 drives the two connecting strips 841 to always tend to move away from each other. The ejector block 845 is fixedly installed on the inside of the gantry 11 and is located directly below the drive block 843.

[0052] The drive block 843 has an inclined surface, and the ejector block 845 has an ejector surface that matches the inclined surface. When the lifting mechanism 5 drives the protective frame 71 to descend, the inclined surface of the drive block 843 contacts the ejector surface of the ejector block 845, causing the drive block 843 to begin moving away from the protective frame 71. This causes the two connecting bars 841 to begin moving closer to each other, thereby causing the heat-generating blocks 82 fixedly installed on the inner side to begin moving closer to each other and contacting the rotating cutting blade 73 and the grinding roller 81 to generate heat.

[0053] Reference Figure 2 as well as Figure 7 The air supply assembly 85 includes an air supply box 851, a second threaded rod 852, a piston plate 853, an air supply pipe 854, and a first synchronization structure 855. The first synchronization structure 855 includes two first synchronization pulleys 8551 and a first synchronization belt 8552.

[0054] A support block 856 is fixedly installed on the movable frame 16, and an air supply box 851 is fixedly installed on the support block 856. A second threaded rod 852 is rotatably installed in the air supply box 851, with one end of the second threaded rod 852 passing through the air supply box 851. A piston plate 853 is threadedly connected to the second threaded rod 852 and slidably installed inside the air supply box 851. An air supply pipe 854 connects the air supply box 851 and the protective frame 71, thereby facilitating the delivery of air from the air supply box 851 to the protective frame 71 via the air supply pipe 854. The air is then generated by the heat-generating block 82, which blows hot air towards the cut, heating the cut and simultaneously blowing the waste from the grinding roller 81 into the gap at the cut for reinforcement, thus preventing deformation of the cut. Two first synchronous pulleys 8551 are fixedly mounted on the first threaded rod 61 and the second threaded rod 852, respectively. The first synchronous belt 8552 is driven and sleeved on the outside of the two first synchronous pulleys 8551. This allows the first motor 63 to drive the first threaded rod 61 to rotate, and the first synchronous pulleys 8551 and the first synchronous belt 8552 to drive the second threaded rod 852 to rotate synchronously. As the cutting blade 73 and the grinding roller 81 move, the piston plate 853 moves synchronously within the air supply box 851. The air is then synchronously delivered to the cutting point through the air supply pipe 854. A sliding frame 857 is fixedly mounted on the air supply box 851. A sliding groove 858 is provided on the gantry frame 11. The sliding frame 857 is slidably installed in the sliding groove 858. This makes the air supply box 851 more stable when it follows the moving frame 16 up and down, thanks to the cooperation of the sliding frame 857 and the sliding groove 858.

[0055] During operation, the second motor 834 is started first, which drives the worm section 832 to rotate. When the worm section 832 rotates, it drives the worm wheel 833 that meshes with it to rotate. When the worm wheel 833 rotates, it drives the starting rod 831 and the grinding roller 81 to rotate. At the same time, through the cooperation between the second synchronous pulley 8351 and the second synchronous belt 8352, the cutting roller 72 and the cutting blade 73 are driven to rotate synchronously.

[0056] After the cutting roller 72 and the cutting blade 73 rotate, the hydraulic cylinder 52 is activated and guided by the second limiting telescopic column 51, which drives the moving frame 16 and the overall cutting mechanism 7 to descend smoothly. At this time, the moving strip 14 slides in the sliding hole 13 and is limited by the limiting block 15 to ensure that the moving frame 16 moves vertically without deviation. As the protective frame 71 continues to move down, the inclined surface of the drive block 843 comes into contact with and is pressed against the ejector block 845 on the inner side of the gantry frame 11. The drive block 843 moves away from the protective frame 71. Under the guidance of the first limiting telescopic column 842, the movement is stable. When the drive block 843 moves, it drives the drive rod 844, which is hinged to it, to rotate. When the drive rod 844 rotates, it pushes the connecting strips 841 on both sides to overcome the elastic force of the compression spring 847 and move closer to each other, so that the two sets of heat-generating blocks 82 are respectively pressed against the rotating cutting blade 73 and the grinding roller 81 surface. Friction generates heat to provide a heat source for subsequent hot air curing.

[0057] When the cutting blade 73 moves to the cutting height, the first motor 63 is started to drive the first threaded rod 61 to rotate. When the first threaded rod 61 rotates, it drives the moving plate 62, which is threaded to it, to slide in the moving groove 64, thereby driving the protective frame 71 and the cutting mechanism 7 to feed horizontally, so that the cutting blade 73 cuts the carton board. At the same time, the grinding roller 81 grinds and trims the burrs at the cut, and heats the cut under the action of friction and the heat generating block 82. Meanwhile, through the cooperation between the first synchronous wheel 8551 and the first synchronous belt 8552, the second threaded rod 852 is driven to rotate synchronously. When the second threaded rod 852 rotates, it drives the piston plate 853, which is threaded to it, to move horizontally in the air supply box 851, and sends the airflow into the protective frame 71 through the air supply pipe 854.

[0058] The airflow delivered by the air supply box 851 through the air supply pipe 854 passes through the heat-generating block 82, thereby turning the delivered air into hot air and blowing the hot air toward the cut position of the carton board. On the one hand, it further heats and solidifies the cut, and on the other hand, it blows the cardboard debris generated by sanding into the micro gap of the cut for filling and reinforcement, improving the strength and flatness of the cut, and preventing deformation at the cut.

[0059] Reference Figure 1 as well as Figure 2 A waste collection component 9 is installed between the workbench 1 and the gantry frame 11 to collect the waste debris blown up by the air conveying component 85 in conjunction with the air conveying component 85.

[0060] In this embodiment, two sets of waste collection components 9 are provided and symmetrically arranged on the gantry frame 11.

[0061] The waste collection assembly 9 includes a fixed base 91, a pump 92, a suction pipe 93, a suction hood 94, a dust discharge pipe 95, and a waste collection box 96.

[0062] Sliding strips 97 are fixedly installed on both sides of the waste collection box 96, and sliding grooves 98 are opened on both sides of the inside of the workbench 1. The two sliding strips 97 are slidably installed in the corresponding sliding grooves 98. A handle 99 is fixedly installed on the waste collection box 96 so that when the waste collection box 96 is full, it can be pulled out for cleaning by using the handle 99. The fixed base 91 is fixedly installed on the gantry frame 11, and the extraction pump 92 is fixedly installed on the fixed base 91. The dust suction pipe 93 is connected to the dust inlet of the extraction pump 92 and passes through the gantry frame 11. The dust suction hood 94 is connected to the dust inlet of the dust suction pipe 93, and the dust exhaust pipe 95 is connected to the dust exhaust port of the extraction pump 92 and passes through the workbench 1. The outlet of the dust exhaust pipe 95 is located directly above the waste collection box 96.

[0063] During operation, by activating the extraction pump 92, a negative pressure adsorption area is formed on both sides of the cutting station by the suction pipe 93 and the suction hood 94. This draws in excess waste and dust generated during grinding, which are blown by the air supply component 85 into the cutting gap, preventing the waste from scattering and contaminating the workbench 1 or adhering to the surface of the cardboard. Simultaneously, the extracted waste and dust are pressurized by the extraction pump 92 and transported by the dust exhaust pipe 95 to the waste collection box 96 inside the workbench 1 for centralized storage. At the same time, during the continuous suction process, the extraction pump 92 drives the air to flow rapidly in the cutting area, providing auxiliary cooling to the cardboard cut that has just been cured by hot air. This allows the softened cardboard fibers at the cut to quickly set, further reducing cut deformation and springback, resulting in a more stable curing effect and higher dimensional accuracy.

[0064] Furthermore, since the waste collection box 96 is installed inside the workbench 1 through the sliding cooperation of the sliding bar 97 and the sliding groove 98, when it is full, the waste collection box 96 can be pulled out directly through the handle 99, which makes it convenient to clean the waste inside.

[0065] Based on the same inventive concept, embodiments of the present invention provide a control method for a cardboard punching equipment.

[0066] A control method for a cardboard die-cutting machine includes the following steps: Step S100: Acquire an image of the workbench surface.

[0067] The workbench surface image refers to a real-time image of the workbench surface area, which can be acquired by a high-definition industrial camera pre-installed on the equipment to ensure that the complete placement of the cardboard boxes to be processed can be clearly captured.

[0068] Step S101: Determine whether the cardboard to be processed is placed in place based on the preset placement position from the workbench surface image.

[0069] The placement position refers to the preset standard placement position of the cardboard boxes. This is determined by the operator based on the equipment structure.

[0070] The image recognition algorithm is used to analyze and process the collected workbench surface image, extract the edge contour, placement angle and position coordinates of the cardboard in the image, and compare the extracted parameters with the placement position to determine whether the cardboard to be processed is placed in place. If it is determined that the cardboard is not placed in place, the equipment stays in standby mode and issues a prompt signal until the cardboard is detected to be placed in place.

[0071] Step S102: When the carton board is placed in place, control the lifting mechanism 5 to drive the cutting mechanism 7 to approach the carton board at a preset pressing height and pressing speed.

[0072] The pressing height refers to the distance the cutting mechanism 7 travels from its initial position to contact the surface of the cardboard, while the pressing speed refers to the speed at which the cutting mechanism 7 descends. The pressing height and speed are preset based on the cardboard thickness, material, and die-cutting process requirements. The pressing action is performed by the lifting mechanism 5 of the equipment. When the cardboard is detected as being in place, the control module sends a control signal to the lifting mechanism 5, driving the cutting mechanism 7 to descend according to the set pressing height and speed, preparing for subsequent die-cutting operations.

[0073] Step S103: During the downward movement of the cutting mechanism 7, the heat-generating block 82 is driven to contact the cutting blade 73 and the grinding roller 81 with a preset initial contact pressure, and at the same time, the air supply component 85 is controlled to supply air with a preset initial air supply power.

[0074] The initial contact pressure refers to the pressure applied when the heat-generating block 82 comes into contact with the cutting blade 73 and the grinding roller 81, which is used to ensure that the heat-generating block 82 can generate a large amount of heat.

[0075] Initial air supply power refers to the power of the air supply component 85 when supplying air, which is used to deliver hot air to the cutting area to assist cutting and preliminarily process the cutting debris.

[0076] The initial contact pressure and initial air supply power are preset according to the carton board material, thickness and punching accuracy requirements. When the cutting mechanism 7 moves down to the preset height, the heat generation block 82 contact action and the air supply component 85 air supply action are started simultaneously.

[0077] Step S104: During the operation of the cutting mechanism 7, the operating current and operating resistance of the cutting blade are collected.

[0078] The cutting blade operating current refers to the real-time current when the cutting blade drive motor is working, and the cutting blade operating resistance refers to the reverse resistance encountered by the cutting blade 73 when it contacts the cardboard for punching. These two parameters can be collected in real time by the current sensor and resistance sensor preset on the equipment.

[0079] Step S105: Obtain the current deviation value based on the cutting blade operating current and the preset standard drying condition current.

[0080] The standard drying current refers to the preset current value of the cutting blade 73 when the cardboard is in a dry state and operating normally. It can be pre-calibrated according to the standard drying state of the cardboard and the punching process parameters. The current deviation value refers to the degree of deviation of the current during the cutting process, which can be calculated by subtracting the standard drying current from the cutting blade's operating current, which is collected in real time.

[0081] Step S106: Obtain the resistance deviation value based on the running resistance of the cutting blade and the preset standard drying condition resistance.

[0082] The standard drying condition resistance refers to the preset resistance value experienced by the cutting blade 73 during normal cutting when the cardboard is in a dry state. It can be calibrated synchronously with the standard drying condition current to adapt to the same cardboard material and cutting process. The resistance deviation value refers to the degree of deviation of the resistance during the cutting process, which can be calculated by subtracting the standard drying condition resistance from the cutting blade's running resistance collected in real time.

[0083] Step S107: Determine whether the cardboard is damp based on the current deviation value and resistance deviation value, and verify the dampness condition.

[0084] By comparing the current deviation value and resistance deviation value with the preset current deviation threshold and preset resistance deviation threshold, if both the current deviation value and resistance deviation value exceed the corresponding threshold, it is preliminarily determined that the cardboard is damp. If either deviation value does not exceed the threshold, the cardboard is determined to be dry, and the punching continues according to normal process parameters.

[0085] After initially determining that the cardboard is damp, it needs to be further verified using a preset dampness verification method to ensure the accuracy of the determination result and avoid misjudgment that could lead to errors in adjusting process parameters. The specific verification method will not be elaborated here, but will be described in detail in subsequent embodiments.

[0086] The preset current deviation threshold refers to the critical value at which the cutting blade's operating current is abnormal, and is set by the operator. The preset resistance deviation threshold refers to the critical value at which the cutting blade's operating resistance is abnormal, and is also set by the operator.

[0087] Step S108: When the cardboard is damp, the initial contact pressure is corrected by a preset enhanced contact pressure to increase the temperature of the heat-generating block 82, the initial air supply power is corrected by a preset enhanced air supply power to increase the hot air output power of the air supply component 85, and the cutting mechanism 7 is controlled to cut by a preset extended cutting speed to extend the hot air curing time of the cut.

[0088] Increased contact pressure, increased air supply power, and extended cutting speed are all preset process parameters adapted to damp cardboard, set by the operator.

[0089] The contact pressure is increased to a higher level than the initial contact pressure to improve the contact tightness between the heat-generating block 82 and the cutting blade 73 and the grinding roller 81, increase the temperature of the cutting blade 73, and prevent moisture from causing paper scraps to stick to the cutting blade 73.

[0090] The increased air supply power is higher than the initial air supply power to improve the hot air output and temperature for drying the cardboard.

[0091] The cutting speed is extended below the normal cutting speed to prolong the time that hot air acts on the cutting area, ensuring that the cut is cured and formed, while also extending the time that the hot air blows.

[0092] Once the moisture test is passed, the control module automatically switches to the enhanced process parameters mentioned above to complete the die-cutting operation of the damp cardboard. During drying, the curing mechanism 8 is controlled to operate with preset conventional parameters to complete the integrated processing of die-cutting, cutting, grinding and hot air curing.

[0093] Methods for verifying moisture conditions include: Step S201: Acquire images of the cut edges of the cardboard.

[0094] The cut-out forming image refers to the real-time image of the cut area during the punching process of the cutting mechanism 7 on the cardboard, which can be acquired by a high-definition industrial camera aimed at the cut position.

[0095] Step S202: Analyze the fiber looseness characteristics from the cut-out forming image.

[0096] Fiber looseness characteristics refer to parameters such as the distribution and looseness of cardboard fibers in the cut area. These characteristics can be obtained by analyzing the acquired cut-out images using image recognition algorithms.

[0097] Step S203: Determine whether the fiber looseness exceeds the preset looseness threshold.

[0098] The looseness threshold refers to a preset critical value for fiber looseness that distinguishes between dry and damp cardboard. The looseness threshold is pre-calibrated based on fiber looseness data of cardboard of different materials and thicknesses under standard dry conditions and different levels of moisture, ensuring accurate differentiation between normal and damp conditions.

[0099] Step S204: When the fiber looseness exceeds the looseness threshold, the moisture condition verification is passed.

[0100] If the fiber looseness value exceeds the preset looseness threshold, it indicates that the carton board is indeed damp, and the degree of dampness reaches the standard that requires adjustment of process parameters. At this time, the verification is passed, and the control module executes the process parameter correction operation in step S108 to ensure the punching quality.

[0101] Step S205: When the fiber looseness does not exceed the looseness threshold, the carton board is not damp, and the machine is stopped for inspection.

[0102] If the fiber looseness value does not exceed the preset looseness threshold, it means that the previous preliminary judgment based on the current deviation value and resistance deviation value was a misjudgment, and the carton board is actually in a dry state. At this time, the equipment stops and issues a warning signal. The staff needs to check the operating status of the current sensor and resistance sensor, find out the cause of the abnormal parameter acquisition, and restore normal operation after troubleshooting.

[0103] Solutions for damp cardboard boxes also include: Step S301: Collect the initial position information, real-time position information, and hot air distribution information of the cutting mechanism 7.

[0104] Initial position information refers to the initial coordinate position of the cutting mechanism 7 before the punching operation begins. Real-time position information refers to the real-time coordinate position of the cutting mechanism 7 during the punching process. Hot air distribution information in the cutting area refers to the distribution of hot air delivered by the air conveying assembly 85 in the cutting area. Both initial and real-time position information can be acquired using position sensors. Hot air distribution information in the cutting area can be acquired using temperature and airflow sensors.

[0105] Step S302: Match the target waste collection component that is close to the cutting mechanism 7 and the non-target waste collection component that is far away from the cutting mechanism 7 according to the initial position information.

[0106] The target waste collection component refers to the waste collection component that is closest to the initial position of the cutting mechanism 7 and can effectively cover the cutting area. The non-target waste collection component refers to the waste collection component 9 that is farther away and cannot effectively cover the cutting area. Based on the initial position information of the cutting mechanism 7 and the fixed position coordinates of the waste collection components 9, the waste collection component 9 that is closest to the initial position of the cutting mechanism 7 and can effectively cover the cutting area can be selected as the target waste collection component, and the waste collection component 9 that is farther away and cannot effectively cover the cutting area can be selected as the non-target waste collection component. Both the non-target and target waste collection components are the waste collection components 9 of the aforementioned mechanical parts.

[0107] Step S303: Match the hot air coverage range of the cut based on the hot air distribution information.

[0108] The cut-out hot air coverage area refers to the area that the hot air output by the air supply component 85 can cover. The cut-out hot air coverage area can be determined by analyzing the collected hot air distribution information in the cut-out area to identify the core coverage area of ​​the hot air in the cut-out area.

[0109] Step S304: Determine the adsorption range of the target waste collection component by combining the hot air coverage range of the cut, real-time location information, and the preset location of the target waste collection component.

[0110] The adsorption range refers to the air intake area that can completely cover the hot air coverage area and completely suck in the hot air in that area, while adapting to the real-time movement trajectory of the cutting mechanism 7.

[0111] The adsorption range can be dynamically adjusted based on the real-time position information of the cutting mechanism 7, and determined by combining the size and shape of the hot air coverage area of ​​the cut and the fixed position of the target waste collection component.

[0112] Step S305: Match the adsorption force of the target waste collection component based on the adsorption range.

[0113] Adsorption force refers to the suction force generated when the target waste collection component is working. Preset adsorption force parameters for different adsorption ranges; the larger the adsorption range, the stronger the required adsorption force. Match the corresponding adsorption force according to the adsorption range determined in step S304 to ensure effective removal of hot air and waste from the cut area.

[0114] Step S306: Determine the cutting direction of the cutting mechanism 7 based on the initial position information and the real-time position information.

[0115] The cutting direction refers to the direction in which the cutting mechanism 7 moves from its initial position to its real-time position. The cutting direction can be obtained by comparing the initial position information and the real-time position information of the cutting mechanism 7 to calculate its movement trajectory.

[0116] Step S307: Control the target waste collection component to use suction force to draw air from the cutting mechanism 7 to remove the hot air from the cut in the opposite direction of the cutting direction, and control the non-target waste collection component to turn off.

[0117] The target waste collection component is activated according to the matching adsorption force, so that it performs air suction in the opposite direction of the cutting direction, sucking away the hot air and waste generated by punching from the cutting area, further heating the carton board to prevent moisture, and preventing waste from sticking to the cutting blade 73 or the surface of the carton board. At the same time, all non-target waste collection components are controlled to shut down.

10. The control method for a cardboard punching equipment according to claim 9, characterized in that, Solutions for damp cardboard boxes also include: Collect the initial position information, real-time position information and hot air distribution information of the cutting mechanism (7); Based on the initial position information, target waste collection components that are close to the cutting mechanism (7) and non-target waste collection components that are far from the cutting mechanism (7) are matched; Match the hot air coverage range of the incision based on hot air distribution information; The adsorption range of the target waste collection component is determined by combining the coverage range of the hot air at the cut, real-time location information, and the preset location of the target waste collection component. The adsorption force of the target waste collection component is matched based on the adsorption range; The cutting direction of the cutting mechanism (7) is determined based on the initial position information and the real-time position information; The target waste collection component is controlled to use adsorption force to draw air from the cutting mechanism (7) to draw away the hot air from the cut in the opposite direction of the cutting direction, and the non-target waste collection component is controlled to close.
