Description

Technical Field

[0001] This invention relates to the field of packaging processing technology, and in particular to a flexible curved ironing device for irregularly shaped packaging boxes. Background Technology

[0002] As the packaging industry places increasing demands on product appearance and texture, irregularly shaped packaging boxes, due to their unique visual design, are increasingly widely used in the food, cosmetics, and gift industries. The outer packaging materials for irregularly shaped boxes are diverse. Common cardboard has good stiffness and plasticity, allowing for the creation of various complex shapes. However, these materials are prone to wrinkles and deformation during processing, severely affecting the overall texture and quality of the packaging. Therefore, ironing is necessary to achieve a smooth surface and shape the edges. Precise ironing not only eliminates surface defects but also enhances the three-dimensionality and stiffness of the packaging, allowing irregularly shaped packaging boxes to better showcase the brand's high-end image and craftsmanship. Therefore, a flexible curved surface ironing device for irregularly shaped packaging boxes is particularly needed.

[0003] However, existing ironing devices for irregularly shaped packaging boxes mostly use rigid flat or fixed curved ironing heads, which can only iron regular flat surfaces or surfaces with a single curvature. For complex structures such as multi-curvature transition surfaces and wavy edges of irregularly shaped packaging boxes, rigid ironing heads cannot fully fit the curved surfaces, resulting in uneven ironing pressure in local areas, high wrinkling rate of packaging paper, and difficulty in achieving stable positioning with traditional positioning mechanisms. During the ironing process, the packaging box is prone to displacement due to vibration or ironing head pressure, resulting in ironing position deviation. It is impossible to adjust according to the material thickness and curvature changes of different curved areas of irregularly shaped packaging boxes. Most of them require manual hand-held ironing tools, which require manual adjustment of the packaging box posture to fit the ironing head. This is not only labor-intensive, but the randomness of manual operation leads to poor consistency of ironing results, and manual operation is prone to introducing foreign object contamination risks, which does not meet industry hygiene standards. Summary of the Invention

[0004] The purpose of this invention is to provide a flexible curved surface ironing device for irregularly shaped packaging boxes, to solve the problems mentioned in the background art. Existing ironing devices for irregularly shaped packaging boxes often use rigid flat or fixed arc-shaped ironing heads, which can only iron regular planes or surfaces with a single curvature. For complex structures such as multi-curvature transition surfaces and wavy edges of irregularly shaped packaging boxes, the rigid ironing head cannot fully conform to the curved surface, resulting in uneven ironing pressure in local areas, high wrinkling rate of the packaging paper, and difficulty in achieving stable positioning using traditional positioning mechanisms. During ironing, the packaging box is prone to displacement due to vibration or ironing head pressure, leading to ironing position deviation. It cannot adjust according to the material thickness and curvature changes of different curved areas of the irregularly shaped packaging box. Most of these devices rely on manual hand-held ironing tools, requiring manual adjustment of the packaging box's posture to fit the ironing head. This is not only labor-intensive, but the randomness of manual operation leads to inconsistent ironing results, and manual operation easily introduces the risk of foreign object contamination, failing to meet industry hygiene standards.

[0008] Preferably, the worktable and the fixed base are fixedly connected, and two identical sets of rotating shafts and rotating rollers are provided, with the two sets of rotating shafts and rotating rollers symmetrically distributed about the vertical center line of the conveyor belt.

[0009] Preferably, the vertical center lines of the telescopic rod, the connecting block, and the connecting plate are located on the same vertical center line, and the sliding rail and the movable seat are slidably connected.

[0010] Preferably, the movable seat, fixed column, and anti-deviation roller are provided in two identical sets, and the two sets of movable seats, fixed columns, and anti-deviation rollers are symmetrically distributed about the vertical center line of the positive and negative thread double-ended lead screw.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The flexible curved ironing device for irregularly shaped packaging boxes of the present invention, by setting an anti-deviation component, has two sets of anti-deviation rollers symmetrically distributed about the positive and negative teeth double-headed screws, which can move synchronously in opposite directions or in the opposite direction under the drive of two motors, adapting to irregularly shaped packaging boxes of different widths. The right-angled trapezoidal structure of the moving seat allows the inclined anti-deviation rollers to fit the curved edge of the packaging box, avoiding damage caused by rigid contact. The sliding cooperation between the sliding rail and the moving seat ensures the accurate movement trajectory of the anti-deviation rollers. One electric cylinder drives one telescopic rod to move the connecting plate up and down, and the height of the anti-deviation rollers can be adjusted according to the height of the irregularly shaped packaging box and the curvature of the surface, ensuring that the anti-deviation rollers are always in close contact with the edge of the packaging box, preventing lateral deviation caused by vibration or pressure during ironing, and greatly improving the stability of operation;

[0017] 2. The flexible curved ironing device for irregularly shaped packaging boxes of the present invention, by setting ironing components, the flexible curved pressure plate at the bottom of the iron and the flexible curved pad at the top of the preheater are the same size, and can deform in real time with the multi-curvature surface of the irregularly shaped packaging box. The two together can cover all curved areas of the packaging box, avoid missed ironing at the joint of the curved surfaces, reduce the wrinkle rate, and significantly improve the flatness of the packaging appearance. Two sets of symmetrically distributed flexible sponge blocks, driven by electric cylinder two, can apply uniform pressure to the complex curved areas such as protrusions and depressions of the irregularly shaped packaging box. Motor three drives the transmission screw to move the moving frame along the slide rail, realizing the dynamic pressing of the flexible sponge blocks along the length of the packaging box. Combined with the heating of the iron, it further eliminates local wrinkles and ensures that the curved surface shaping effect is consistent. At the same time, the ironed packaging box can be clamped and moved to the inclined seat for collection.

[0018] 3. The flexible curved ironing device for irregularly shaped packaging boxes of the present invention guides the ironed packaging boxes to slide smoothly onto the collection ramp by setting an inclined seat with a front-high and rear-low structure. The triangular structure of the collection ramp uses gravity to make the packaging boxes slide automatically into the collection trough. The guardrails on both sides prevent the packaging boxes from falling. The infrared alarm will sound an alarm and stop the machine in real time when there is accumulation or personnel accidentally enter. At the same time, it will detect whether the product is qualified to ensure production safety. The flexible curved pressure plate, flexible curved pad and flexible sponge block are made of flexible materials that can be adapted to curved surfaces with different curvatures. There is no need to replace them separately for each specification, which reduces the cost of spare parts. It can meet the production needs of various irregularly shaped packaging boxes in the food, cosmetics, gift and other industries. It has strong versatility and wide application range.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] Please see Figure 1-7This invention provides a technical solution: a flexible curved ironing device for irregularly shaped packaging boxes, including a workbench 1, a mounting base 2 fixedly installed on the top of the workbench 1, a motor 3 fixedly installed on the top of the mounting base 2, a rotating shaft 4 fixedly installed at the output end of the motor 3, a rotating roller 5 fixedly installed on the outer side of the rotating shaft 4, a conveyor belt 6 rotatably installed on the outer side of the rotating roller 5, a fixed seat 7 provided on the outer side of the rotating shaft 4, a frame 8 fixedly installed on the top of the workbench 1, an anti-deviation component 9 provided at the bottom of the frame 8, an ironing component 10 provided on the top of the workbench 1, a support column 11 fixedly installed on the top of the workbench 1, an inclined seat 12 fixedly installed on the top of the support column 11, a collection ramp 13 fixedly installed on the top of the workbench 1, a guardrail 14 fixedly installed on the top of the collection ramp 13, an infrared alarm 15 fixedly installed on the top of the guardrail 14, and a collection trough 16 fixedly installed on the top of the workbench 1.

[0030] Furthermore, the ironing assembly 10 includes a mounting bracket 1001, which is mounted on the workbench 1. An iron 1002 is fixedly mounted on the bottom of the mounting bracket 1001. A flexible curved pressure plate 1003 is provided at the bottom of the iron 1002. A preheater 1004 is fixedly mounted on the top of the workbench 1. An exhaust port 1005 is provided on the outer side of the preheater 1004. A heat dissipation groove 1006 is provided on the top of the preheater 1004. A connecting column 1007 is fixedly mounted on the top of the preheater 1004. A flexible curved pad 1008 is fixedly installed on the workbench 1. A mounting base plate 1009 is fixedly installed on the top of the mounting base plate 1009. A motor 3 1010 is fixedly installed on the top of the mounting base plate 1009. A transmission screw 1011 is fixedly installed on the output end of the motor 3 1010. A movable frame 1012 is threadedly connected to the outer side of the transmission screw 1011. A mounting base plate 2 1013 is fixedly installed on the bottom of the movable frame 1012. An electric cylinder 2 1014 is fixedly installed on the bottom of the mounting base plate 2 1013. A movable end of the electric cylinder 2 1014 is fixedly installed with... Telescopic rod 1015, with a flexible sponge block 1016 fixedly installed at the end of telescopic rod 1015 away from the electric cylinder. A slide rail 1017 is fixedly installed on the top of the workbench 1. By setting up the ironing component 10, the flexible curved pressure plate 1003 at the bottom of the ironing machine 1002 and the flexible curved pad 1008 at the top of the preheating machine 1004 are the same size. They can deform in real time according to the multi-curvature surface of the irregularly shaped packaging box. The two work together to cover all curved areas of the packaging box, avoid missed ironing at the joints of the curved surfaces, reduce the wrinkle rate, and significantly improve the flatness of the packaging appearance. Two sets of symmetrically distributed flexible sponge blocks 1016, driven by electric cylinder 1014, can apply uniform pressure to complex curved areas such as protrusions and depressions of irregularly shaped packaging boxes. Motor 1010 drives transmission screw 1011 to move moving frame 1012 along slide rail 1017, realizing dynamic pressing of flexible sponge blocks 1016 along the length of packaging box. Combined with the heating of iron 1002, local wrinkles are further eliminated, ensuring consistent surface shaping effect. At the same time, the ironed packaging box can be clamped and moved to inclined seat 12 for collection.

[0031] Furthermore, the anti-deviation assembly 9 includes a mounting plate 901, which is installed at the bottom of the frame 8. An electric cylinder 902 is fixedly mounted on the bottom of the mounting plate 901. A telescopic rod 903 is fixedly mounted on the movable end of the electric cylinder 902. A connecting block 904 is fixedly mounted on the end of the telescopic rod 903 away from the electric cylinder 902. A connecting plate 905 is fixedly mounted on the bottom of the connecting block 904. A mounting base 906 is fixedly mounted on the outer side of the connecting plate 905. A second motor 907 is fixedly mounted on the bottom of the mounting base 906. A double-ended lead screw 908 with positive and negative threads is fixedly mounted on the output end of the second motor 907. A movable seat 909 is threadedly connected to the outer side of the double-ended lead screw 908. A fixed column 910 is fixedly mounted on the bottom of the movable seat 909. An anti-deviation roller 911 is rotatably mounted on the outer side of the fixed column 910. The connecting plate 905... A sliding rail 912 is fixedly installed at the bottom. With the addition of an anti-deviation component 9, two sets of anti-deviation rollers 911, symmetrically distributed about the positive and negative thread double-headed lead screws 908, can move synchronously in opposite directions or in the opposite direction under the drive of motor 907, adapting to irregularly shaped packaging boxes of different widths. The right-angled trapezoidal structure of the moving seat 909 allows the inclined anti-deviation rollers 911 to fit the curved edge of the packaging box, avoiding damage caused by rigid contact. The sliding cooperation between the sliding rail 912 and the moving seat 909 ensures the precise movement trajectory of the anti-deviation rollers 911. The electric cylinder 902 drives the telescopic rod 903 to move the connecting plate 905 up and down, which can adjust the height of the anti-deviation rollers 911 according to the height and curvature of the irregularly shaped packaging box, ensuring that the anti-deviation rollers 911 are always in close contact with the edge of the packaging box, preventing lateral deviation caused by vibration or pressure during ironing, and greatly improving operational stability.

[0032] Furthermore, the workbench 1 and the fixed base 7 are fixedly connected. Two identical sets of rotating shafts 4 and rotating rollers 5 are provided, and the two sets of rotating shafts 4 and rotating rollers 5 are symmetrically distributed about the vertical center line of the conveyor belt 6. By setting the rotating shafts 4 and rotating rollers 5, the problem of uneven force and deviation of the conveyor belt 6 caused by unilateral drive is avoided. The fixed connection between the fixed base 7 and the workbench 1 provides stable support for the rotating shafts 4, preventing shaft deviation due to vibration during rotation, ensuring that the rotating rollers 5 rotate at a consistent speed, and thus keeping the conveyor belt 6 running at a uniform speed. This can prevent the irregularly shaped packaging boxes from tilting due to speed fluctuations during transmission, providing a stable material conveying foundation for subsequent anti-deviation positioning and ironing operations, and improving transmission stability.

[0033] Furthermore, the vertical center lines of the telescopic rod 903, connecting block 904, and connecting plate 905 are located on the same vertical center line. The sliding rail 912 and the moving seat 909 are slidably connected. By setting the telescopic rod 903, connecting block 904, and connecting plate 905, it can be ensured that the connecting plate 905 rises and falls smoothly in the vertical direction when the electric cylinder 902 is driven, avoiding the height adjustment error of the anti-deviation roller 911 caused by force deviation. The sliding cooperation between the sliding rail 912 and the moving seat 909 provides precise guidance for the moving seat 909, preventing the moving seat 909 from shifting laterally under the drive of the positive and negative thread double-headed screw 908, ensuring that the two sets of anti-deviation rollers 911 always move symmetrically about the center line of the conveyor belt 6, further improving the positioning accuracy of the irregularly shaped packaging box, and avoiding ironing leaks or pressure damage caused by positioning deviation.

[0034] Furthermore, the movable seat 909, fixed column 910, and anti-deviation roller 911 are all provided in two identical sets, and the two sets of movable seats 909, fixed column 910, and anti-deviation roller 911 are symmetrically distributed about the vertical center line of the double-ended screw 908. By setting two sets of movable seats 909, fixed column 910, and anti-deviation roller 911, the torsion of the packaging box caused by unilateral positioning is avoided. When the motor 907 drives the double-ended screw 908 to rotate, the two sets of movable seats 909 can move synchronously in opposite directions to adapt to irregularly shaped packaging boxes of different widths. The symmetrical positioning on both sides can reduce the positioning deviation of the packaging box and greatly reduce the scrap rate caused by inaccurate positioning.

[0035] Furthermore, the movable base 909 has a right-angled trapezoidal structure, and the fixed column 910 is located on one side of the inclined surface of the movable base 909. The fixed column 910 and the anti-deviation roller 911 have an inclined structure. By setting the fixed column 910 and the anti-deviation roller 911, the rigid collision between the traditional vertical anti-deviation structure and the curved edge is avoided, reducing the risk of scratches or deformation on the edge of the packaging box. The right-angled trapezoidal structure of the movable base 909 provides an inclined installation reference for the fixed column 910, ensuring that the inclination angle of the anti-deviation roller 911 is adapted to the curved surface of the edge of the packaging box, thereby increasing the contact area between the anti-deviation roller 911 and the packaging box and significantly enhancing the positioning stability. At the same time, by replacing the fixed column 910 with different inclination angles, it can adapt to more complex curved irregular-shaped packaging boxes.

[0036] Furthermore, multiple sets of heat dissipation slots 1006 are provided, and these multiple sets of heat dissipation slots 1006 are located on the top of the preheater 1004 and are equidistantly distributed. The size of the flexible curved pressure plate 1003 is consistent with the size of the flexible curved pad 1008. By setting the flexible curved pressure plate 1003 and the flexible curved pad 1008, the problem of local lack of support and uneven pressure caused by size deviation is avoided. The flexible curved pressure plate 1003 and the flexible curved pad 1008 can deform synchronously with the multi-curvature surface of the irregularly shaped packaging box, covering all curved areas of the packaging box. At the same time, the heat dissipation slots 1006 equidistantly distributed on the top of the preheater 1004 can quickly dissipate local high temperature, and together with the exhaust port 1005, exhaust the hot and humid air, avoiding local overheating and carbonization of the packaging box, and providing a uniform temperature basis for subsequent ironing.

[0037] Furthermore, two identical sets of mounting base plate 1013, electric cylinder 1014, telescopic rod 1015, and flexible sponge block 1016 are provided, and the two sets of mounting base plate 1013, electric cylinder 1014, telescopic rod 1015, and flexible sponge block 1016 are symmetrically distributed about the vertical center line of the moving frame 1012. The slide rail 1017 is slidably connected to the moving frame 1012. By providing two sets of mounting base plate 1013, electric cylinder 1014, telescopic rod 1015, and flexible sponge block 1016, single... The deformation of the packaging box caused by lateral pressure can be addressed by the electric cylinder 1014 driving the telescopic rod 1015 to independently adjust the height and pressure of the flexible sponge block 1016, adapting to the undulations of different areas of the packaging box. In conjunction with the motor 1010 driving the moving frame 1012 to move along the slide rail 1017, the flexible sponge block 1016 is dynamically pressed along the length of the packaging box, further eliminating local wrinkles. The two sets of flexible sponge blocks 1016 can also work together to clamp the ironed packaging box and accurately transfer it to the tilting seat 12, avoiding secondary damage caused by manual transfer.

[0038] Furthermore, the inclined seat 12 has a front-high-rear-low structure, and the inclined seat 12 fits tightly with the collection ramp 13. Two identical sets of guardrails 14 and infrared alarms 15 are provided, and the two sets of guardrails 14 and infrared alarms 15 are symmetrically distributed about the vertical center line of the collection ramp 13. The collection ramp 13 is in contact with the collection trough 16. By setting two sets of guardrails 14 and infrared alarms 15, the two sets of guardrails 14 can form protection from both sides of the collection ramp 13 to prevent irregularly shaped packaging boxes from falling from both sides due to excessive speed or irregular curvature during the sliding process. The infrared alarm 15 adopts the infrared beam principle to monitor the material accumulation of the collection ramp 13 and the collection trough 16 in real time. When the accumulation height exceeds the preset value or a person accidentally enters the danger zone, it can issue an audible and visual alarm and trigger the equipment to stop, avoiding blockage or safety accidents caused by accumulation. At the same time, the infrared alarm 15 can also work with the data acquisition module to identify whether there are obvious ironing defects in the packaging boxes and provide alarm prompts for unqualified products, further improving the product qualification rate.

[0039] Working Principle: First, the operator places the workbench 1 on a level, stable surface, checks the installation status of each component, and starts motor 3. Motor 3 drives the rotating shaft 4, which in turn drives two sets of symmetrically distributed rotating rollers 5 to rotate synchronously, thereby making the conveyor belt 6 run at a uniform speed. The operator neatly places the irregularly shaped packaging boxes to be ironed at the feeding end of the conveyor belt 6, ensuring that the bottom of the packaging box is tightly fitted to the conveyor belt 6. The amount of packaging boxes fed at one time should not exceed the upper limit of the conveyor belt 6 to avoid collisions that could cause misalignment. When the packaging box moves with the conveyor belt 6 to below the anti-deviation component 9, motor 2 907 is started. Motor 2 907 drives the double-ended lead screw 908 with positive and negative threads to rotate, causing two sets of symmetrical moving seats 909 to move synchronously towards each other along the sliding rail 912, thus making the tilted design... The anti-deviation roller 911 conforms to the curved edge of the packaging box. The right-angled trapezoidal movable seat 909 ensures the contact area between the anti-deviation roller 911 and the curved surface, avoiding rigid collisions. At the same time, the electric cylinder 902 drives the telescopic rod 903 to adjust the height of the connecting plate 905, ensuring that the anti-deviation roller 911 is always in close contact with the edge of the packaging box. This ensures that the packaging box moves along the center line of the conveyor belt 6 to the preheating area. The positioned packaging box enters the preheating machine 1004 along with the conveyor belt 6. The preheating machine 1004 starts and generates a stable preheating temperature. The heat is evenly transferred to the outer packaging of the packaging box through the flexible curved pad 1008 on the top. During the preheating process, the exhaust port 1005 on the outside of the preheating machine 1004 discharges hot and humid air in real time, and the heat dissipation grooves 1006 evenly distributed on the top quickly exhaust the humid air. To prevent localized overheating and carbonization of the packaging box, the packaging paper temperature is raised evenly, reducing temperature impact during subsequent ironing. After preheating, the packaging box is moved to the core area of ​​the ironing assembly 10. The iron 1002 at the bottom of the mounting frame 1001 is activated. The flexible curved pressure plate 1003 at the bottom deforms in real time with the multi-curvature surface of the packaging box, providing comprehensive ironing. The iron 1002 heats in zones according to preset temperatures, ensuring consistent ironing results across different curved areas. Ironing pressure is controlled by the iron 1002's own weight and the elasticity of the flexible material, preventing uneven pressure that could cause wrinkles. Motor 3 1010 is activated, driving the transmission screw 1011 to move the moving frame 1012 along the slide rail 1017 at a uniform speed. Simultaneously, two sets of electric cylinders... The second 1014 drive telescopic rod 1015 to lower the flexible sponge block 1016 and conform it to the curved surfaces on both sides of the packaging box. The flexible sponge block 1016 dynamically presses along the length of the packaging box according to the surface undulations, further eliminating wrinkles in complex areas such as corners and protrusions. The pressing time is synchronized with the main ironing to ensure the overall flatness of the packaging box. After ironing, the third motor 1010 continues to drive the moving frame 1012 to move above the tilting seat 12. The two sets of flexible sponge blocks 1016 appropriately increase the pressure, working together to clamp the packaging box, which is then transferred to the top of the tilting seat 12 with the moving frame 1012. The tilting seat 12 has a front-high, back-low structure. After releasing the flexible sponge block 1016, the packaging box slides smoothly towards the collection ramp 13 under gravity, avoiding secondary damage caused by manual handling.As the packaging boxes slide down the collection ramp 13, the guardrails 14 on both sides prevent them from falling due to their irregular curved surfaces. The infrared alarm 15 at the top of the collection ramp 13 monitors the boxes in real time using infrared beams. If the height of the packaging boxes in the collection trough 16 exceeds a preset value, or if any personnel accidentally enter the danger zone, the infrared alarm 15 immediately sounds an audible and visual alarm and triggers the equipment to stop, preventing blockages or accidents. Simultaneously, the infrared alarm 15, in conjunction with a data acquisition module, identifies whether the packaging boxes have serious wrinkles, damage, or other defects, providing an alarm for non-conforming products. Operators can then promptly sort the boxes. If continued mass production is required, the above steps are repeated. After production, all motors and heating components are shut down, and residual impurities on the conveyor belt 6, flexible curved pressure plate 1003, and flexible sponge block 1016 are cleaned to prepare for the next production run.
