Description

Technical Field

[0001] This invention relates to the field of automatic adhesive-applying box-making technology, and in particular discloses an automatic adhesive-applying box-making device and a box-making method. Background Technology

[0002] The development space of paper box forming machines is closely related to the application prospects of paper box packaging. With the continuous improvement of consumers' requirements for product packaging appearance and the continuous pursuit of efficiency and quality in industrial production, paper box packaging is generally bonded to the box body using hot melt adhesive tape. The hot melt adhesive tape also needs to be heated during use. Therefore, the equipment needs to be equipped with heating components, which makes the existing automatic adhesive bonding and box making equipment relatively complex in structure and relatively expensive, and still needs to be improved. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide an automatic adhesive-applying box-making device and a box-making method.

[0004] To achieve the above objectives, the present invention provides an automatic adhesive-applying box-making device and a box-making method, comprising a frame, a cardboard feeding mechanism and a box-ejecting mechanism used in conjunction with the frame, wherein the cardboard feeding mechanism and the box-ejecting mechanism are respectively used for feeding in external cardboard and removing formed boxes, and the frame is provided with an adhesive-applying mechanism for applying tape to external cardboard and a forming mechanism for bending and forming external cardboard.

[0005] The adhesive applicator includes a first frame mounted on a machine frame, a roller rotatably mounted on the first frame, the roller being used to apply external adhesive tape to the first side of the cardboard, the first frame being used to hold the external adhesive roll, and the first frame also having a blade for cutting the tape and a first drive unit for driving the blade closer to / away from the tape. The adhesive applicator accurately applies the tape to the cardboard through the roller, and with the blade and the first drive unit, it can precisely control the cutting position and length of the tape, ensuring the accuracy and consistency of each application, without the need for further heating of the tape.

[0006] The forming mechanism includes a folding module and a second driving component for driving the folding module. The folding module is used to bend the outer cardboard into a box shape. The folding module includes a limiting component that abuts against the side of the cardboard to bend it into a box. The folding module also includes a brush for brushing the protruding end of the adhesive tape attached to the first side of the bent box onto the second side adjacent to the first side. No heating mechanism is required to directly complete the application, making the adhesive application process more convenient and simplifying the operation. The folding module in the forming mechanism adopts a mechanical driving method, which can quickly and accurately bend the cardboard into a box shape. The limiting component further ensures the stability and consistency of the forming process and prevents deviation or deformation during the forming process.

[0007] Furthermore, the first frame is equipped with a guide roller that works with the roller body to guide the tape to adhere to the external cardboard, and a second sensor switch for sensing the position of the cardboard.

[0008] The second sensor switch works in conjunction with the first drive unit. After the external tape is applied to the marked position, the first drive unit drives the blade to cut the tape and reset, ready for the next operation. A central control component is also installed on the first frame. The second sensor switch controls the first drive unit through the central control component. The second sensor switch can sense the running status of the cardboard in real time, especially at the critical moment when the tape application is complete. When the tape on the cardboard reaches the predetermined position, the second sensor switch sends a signal to the central control component. Upon receiving the signal, the central control component controls the first drive unit to move the blade closer to the tape for precise cutting. After cutting, the blade automatically resets, ready for the next operation. The guide roller, as a tape guide device, ensures that the tape, driven by the roller, is applied to the cardboard along a stable and precise path, avoiding tape deviation or twisting during the application process and improving application accuracy.

[0009] Furthermore, the origami module includes an adsorption component for limiting the cardboard and a third driving component for driving the adsorption component to reciprocate. The adsorption component includes a telescopic rod, adsorption elements mounted on the telescopic rod, and a support plate for supporting the external cardboard. The support plate is located at the lower part of the adsorption component. The adsorption elements are used to cooperate with an external pump or vacuum generator to adsorb the cardboard. There are multiple adsorption elements arranged in an array. The telescopic rod and the adsorption elements mounted on it can accurately adsorb and fix the box, so that the box can maintain a stable position and posture during the origami process, avoiding forming errors caused by movement or displacement. The arrayed adsorption elements can provide a more uniform adsorption force, making the box more stable during movement and helping to reduce forming failures or quality problems caused by vibration or external force interference.

[0010] Furthermore, in this embodiment, the cardboard is conveyed to the carrier plate and then bent into shape by the adsorption component set above the carrier plate. While the cardboard is being bent into shape by the adsorption component, or after it is bent into shape, the brush is driven by the fourth driving component to apply tape to the corners of the cardboard box. After the corners are applied, the cardboard box is adsorbed and carried out by the adsorption component and transferred to the discharge mechanism. Finally, the cardboard box is removed by the discharge mechanism.

[0011] Furthermore, the origami module also includes a second frame that is movably mounted relative to the main frame. Two limiting components are mounted on the second frame. The two limiting components are used to limit the two ends of the cardboard that are far apart from each other. The two limiting components limit the two sides of the box body respectively, ensuring the accurate positioning of the box body during the origami process. Precise positioning avoids forming errors caused by positional deviation, improves the forming accuracy of the product, and double-sided positioning can more comprehensively control the shape and position of the box body, making the box body more stable during the origami process and reducing forming failures or quality problems caused by vibration or external force interference.

[0012] Furthermore, the second frame is also equipped with a fourth driving component. A brush is located at the output end of the fourth driving component. The fourth driving component is used to drive the brush to contact the protruding end of the tape attached to the first side. The brush evenly brushes the protruding end of the tape on the first side to the other side of the adjacent side, achieving perfect adhesion of the tape to the box. The automated operation of the brush can handle the tape more precisely, so that the tape can be adhered to the box without the need for hot melt adhesive or a component for heating the hot melt adhesive tape. This reduces production costs, improves production efficiency, and makes the production process smoother and more efficient.

[0013] Furthermore, the frame is equipped with two limit plates, located on either side of the cardboard feeding mechanism and the box ejection mechanism in the width direction. The adjacent distance between the two limit plates can be adjusted to guide the external cardboard / box. The limit plates can precisely restrict the cardboard to the position to be conveyed, ensuring the positional stability of the cardboard during the conveying process. This helps to ensure that the subsequent glue application is accurately aligned with one side of the cardboard, improving processing accuracy. By adjusting the adjacent distance of the limit plates, it can accommodate boxes of different sizes and shapes, reducing processing errors caused by cardboard position deviation. The limit plates enable the equipment to continuously convey and process multiple boxes without the need for frequent manual adjustments to the cardboard position, thus improving production efficiency.

[0014] Furthermore, the frame is equipped with a first inductive switch to detect any abnormalities in the cardboard. The frame also features a holding assembly for use with the gluing mechanism. This assembly has multiple rotatable wheels and an annular belt fitted around the outside of these wheels. The holding assembly ensures the cardboard remains flat and properly positioned during the gluing process. The holding assembly is adjustable on the frame. The first inductive switch can detect material overlap in real time. If overlap is detected, an alarm signal is immediately triggered to stop operation, preventing overlapping material from entering the processing area and thus avoiding product quality issues caused by overlapping processing. The real-time detection function of the first inductive switch can immediately trigger a stop signal when material overlaps, reducing downtime caused by overlapping processing. Overlapping material can damage the processing equipment, such as causing jamming or wear. The detection function of the first inductive switch prevents overlapping material from entering the processing area, protecting the equipment from damage and extending its service life.

[0015] Furthermore, the adsorption assembly includes a first plate with strip-shaped grooves. A telescopic rod is slidably mounted on the first plate via the grooves. There are two parallel grooves, and multiple adsorption elements are provided. The spacing between the multiple adsorption elements is freely adjustable, which can be achieved by sliding the telescopic rod within the grooves. This allows the adsorption assembly to achieve optimal adsorption by adjusting the spacing of the adsorption elements and adapt to objects of different sizes. In this embodiment, the telescopic rod serves as an adjusting element, clamping the first plate to fix / movably mount the multiple adsorption elements on it. Other bolt-type components can also be used for this adjustment, which will not be elaborated upon here.

[0016] Furthermore, the frame is equipped with a first slide rail, on which two second slide rails slide. The second frame body slides on the second slide rails. A second drive unit drives the origami module to move along the second slide rails in the X-axis direction. A fourth drive unit is also provided on the frame, which drives the second slide rails to move along the first slide rails in the Y-axis direction. By using the fourth drive unit to drive the second slide rails to move along the first slide rails in the Y-axis direction, and combining this with the second drive unit to drive the origami module to move along the second slide rails in the X-axis direction, the origami module achieves free movement within a two-dimensional plane. This design greatly improves the flexibility of the origami module, enabling it to perform more complex tasks.

[0017] Furthermore, the frame is equipped with end feet and wheels for use with the end feet. The end feet are equipped with telescopic components, which are used to adjust the distance between the frame and the ground. By adjusting the telescopic components, the distance between the frame and the ground can be easily adjusted, making it adaptable to different ground environments with different heights and flatness. In uneven ground or scenarios requiring stable support, adjusting the telescopic components to maintain stable contact between the frame and the ground can significantly improve the overall stability of the equipment. When the machine needs to be moved, it reduces the manpower required for movement, lowers labor intensity, and improves work efficiency.

[0018] Furthermore, the frame is equipped with a base plate for use with the folding module. Located at the bottom of the folding module, the base plate serves as a stable platform to support the cardboard to be processed. This not only provides a stable working surface for the cardboard but also helps improve the accuracy and efficiency of the folding module during the folding process. Specifically, the base plate reduces the swaying and displacement of the cardboard during folding, making the operation of the folding module more precise and thus reducing the possibility of forming errors.

[0019] Furthermore, an automatic adhesive-applied box-making method specifically includes the following steps:

[0020] S1: The cardboard to be folded into a box is fed into the cardboard one by one using the cardboard feeding mechanism. The cardboard feeding mechanism can automatically and continuously feed the cardboard into the next process without manual placement, which greatly saves manpower and time. The cardboard is limited by the drive limit plate. The limit plate limits the cardboard according to the preset size and position, which reduces the cardboard size deviation or position error caused by improper stacking, thereby ensuring the product quality in subsequent processing. Through the limiting effect of the limit plate, the risk of the cardboard falling due to unstable position during the conveying process can be reduced, thereby reducing the risk of accidents caused by the cardboard falling.

[0021] S2: The cardboard is fed to the gluing mechanism via the cardboard feeding mechanism for gluing. The gluing mechanism is equipped with rotating rollers that press the adhesive tape supplied by the gluing mechanism onto the first side of the cardboard. The cardboard feeding mechanism ensures that the cardboard is delivered to the gluing mechanism accurately and stably, realizing continuous cardboard feeding and gluing, ensuring the continuity and stability of the production line. The cardboard is accurately fed to the gluing mechanism via the cardboard feeding mechanism. The guide rollers and rollers work together to achieve precise adhesion between the adhesive tape and the cardboard. Combined with the precision cutting of the blade and the first drive component, this not only greatly improves the accuracy and production efficiency of gluing, but also significantly ensures the consistency and durability of product quality. At the same time, it reduces labor and material costs and enhances the flexibility and market competitiveness of the production line.

[0022] S3: The glued cardboard is sent to the forming mechanism for bending and shaping. The forming mechanism uses a folding module to fold the cardboard into a box shape. A third drive unit drives the adsorption assembly, allowing the cardboard to be adsorbed upwards. Combined with the precise drive of the second drive unit by the folding module, the cardboard is quickly and accurately bent into shape. This process not only improves production efficiency but also ensures the accuracy and consistency of box forming, further enhancing product quality and meeting market demands for high-quality packaging.

[0023] S4: The brush configured in the adhesive applicator is used to apply the extended end of the tape on the first side of the bent box to the second side adjacent to the first side. After bending, the brush is driven to apply the extended end of the tape on the first side of the bent box to the second side adjacent to the first side, so as to achieve perfect adhesion of the tape on the box. This reduces the need for manual adjustment of the tape position, reduces labor costs and the risk of human error, and at the same time makes the production process smoother and more efficient.

[0024] S5: After the tape is applied using the brush, the box is removed via the ejection mechanism. The adsorption components in the folding module stably adhere and fix the pre-formed box, which has been initially shaped. The third drive component then removes the box after tape application. The telescopic rod and the array of adsorption components work together to ensure precise positioning and stability of the box during the folding process, significantly reducing forming errors caused by movement or offset. Finally, this efficient and stable adsorption system allows for easy and accurate removal of the formed box. The entire process improves production efficiency while ensuring the quality and consistency of the formed boxes.

[0025] The beneficial effects of this invention are as follows: Through a precise adhesive applicator, the tape can be accurately and consistently applied to the cardboard, ensuring accuracy and product quality. The folding module in the forming mechanism, combined with limiting components and adsorption components, not only quickly and accurately folds the cardboard into a box shape, but also ensures the stability and consistency of the box forming through double-sided limiting and uniform adsorption force. Furthermore, by using a brush to apply the extended end of the tape attached to the first side of the bent box to the adjacent second side, manual intervention is effectively reduced, thus improving production efficiency. Ordinary methods can be directly used... The film rolls are also convenient for manufacturers to customize, and the cost is relatively low; the sensor switches and drive components on the frame work together to achieve accurate material detection and automated processing, effectively preventing damage to the equipment from overlapping materials and ensuring production safety. The precision adhesive applicator ensures that ordinary tape is consistently applied to the cardboard, ensuring the accuracy of the adhesive application and product quality; it eliminates the need for expensive hot melt adhesive tape and the need for additional heating components that require heating the hot melt adhesive tape, while meeting the needs of large-volume production and significantly improving the overall performance and market competitiveness of the production line.

[0037] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0038] Please see Figures 1 to 9 As shown, an automatic adhesive-applying box-making device of the present invention includes a frame 1, a cardboard feeding mechanism 5 and a box-ejecting mechanism 6 used in conjunction with the frame 1. The cardboard feeding mechanism 5 and the box-ejecting mechanism 6 are respectively used for feeding in external cardboard and taking out the formed box. The frame 1 is provided with an adhesive-applying mechanism for applying tape to external cardboard and a forming mechanism for bending and forming external cardboard.

[0039] The adhesive applicator includes a first frame 21 mounted on a frame 1 and a roller 25 rotatably mounted on the first frame 21. The roller 25 is used to apply external adhesive tape to the first side of the cardboard. The first frame 21 is used to hold the external adhesive roll. The first frame 21 is also equipped with a blade for cutting the adhesive tape and a first drive unit 22 for driving the blade to approach / move away from the adhesive tape. The adhesive applicator accurately applies the adhesive tape to the cardboard through the roller 25. It is equipped with a blade and a first drive unit 22, which can precisely control the cutting position and length of the adhesive tape, ensuring the accuracy and consistency of each application.

[0040] The forming mechanism includes a folding module 3 and a second driving component 12 for driving the folding module 3. The folding module 3 is used to bend the outer cardboard into a box shape. The folding module 3 includes a limiting component 13, which abuts against the side of the cardboard to bend it into a box. The folding module 3 also includes a brush 4 for brushing the protruding end of the tape attached to the first side of the bent box onto the second side adjacent to the first side. The folding module in the forming mechanism adopts a mechanical driving method, which can quickly and accurately bend the cardboard into a box shape. The limiting component 13 further ensures the stability and consistency of the forming process and prevents deviation or deformation during the forming process.

[0041] Specifically, in this embodiment, the external film can be a commercially available roll of adhesive tape.

[0042] Specifically, the production and manufacturing of external film uses existing conventional technology. Purchasing conventional film and enabling automatic tape application facilitates manufacturers' purchase and customization of the required tapes. For example, various parameters of the external film (such as width, thickness, and number of rolls) can be customized. When customizing tapes, the overall length of the tape can be increased, reducing the frequency of tape replacement. This allows the box-making device to operate continuously for longer periods without interruption, thereby avoiding the time and effort spent by workers on tape replacement.

[0043] Specifically, conventional tape can better bond a variety of materials, including paper and plastic, making it more widely applicable. Furthermore, depending on the size of the cardboard box, wider or longer tapes can be used for application, ensuring the box remains stable.

[0044] Specifically, in other embodiments, the first frame 21 can also be equipped with fiber tape according to user needs to improve the stability of the box after molding. The fiber tape is made of PET as the base material, with reinforced polyester fiber threads inside, and coated with special pressure-sensitive adhesive. The fiber tape has excellent wear resistance and moisture resistance, extremely strong tensile strength, and the unique pressure-sensitive adhesive layer has excellent long-lasting adhesion and special properties, making it very versatile and enabling the box to be more solid after molding.

[0045] Specifically, the first frame 21 is provided with a shaft for mounting external film. The shaft is detachably mounted on the first frame 21, and shafts of corresponding lengths can be installed according to user needs to accommodate external film of different widths.

[0046] Specifically, the tape is accurately attached to the cardboard by the roller 25, ensuring the precision of the tape application position. Secondly, the blade and the first drive unit 22 equipped on the first frame 21 allow for precise control of the tape cutting position and length, reducing the scrap rate caused by inaccurate or inconsistent tape application. This helps to reduce production costs and improve product quality. Only one blade is needed in conjunction with the first drive unit 22 to complete the cutting work, greatly simplifying the operation process and effectively improving production efficiency.

[0047] Specifically, the origami module 3 also includes a brush 4. The brush 4 is used to brush and stick the protruding end of the tape attached to the first side of the bent box to the second side adjacent to the first side. The tape can be directly applied by brushing the brush 4, without the need to set up a heating mechanism to heat the hot melt adhesive tape, which makes the application process more convenient and simplifies the operation process.

[0048] Specifically, in this embodiment, multiple adhesive application mechanisms are provided.

[0049] Specifically, the first frame 21 is equipped with a guide roller 23 that works with the roller body 25 to guide the tape to adhere to the outer cardboard, and a second sensor switch 24 for sensing the position of the cardboard;

[0050] The second sensor switch 24 works in conjunction with the first drive unit 22 to attach external tape to a designated position. The first drive unit 22 drives the blade to cut the tape and resets, ready for the next operation. A central control component is also installed on the first frame 21. The second sensor switch 24 controls the first drive unit 22 through the central control component. The second sensor switch 24 can sense the running status of the cardboard in real time, especially at the critical moment when the tape is applied. When the tape on the cardboard reaches the predetermined position, the second sensor switch 24 sends a signal to the central control component. After receiving the sensing signal, the central control component controls the first drive unit 22 to drive the blade to approach the tape for precise cutting. After cutting, the blade automatically resets for the next operation. The guide roller 23, as a tape guide device, ensures that the tape is attached to the cardboard in a stable and precise path under the drive of the roller body 25, avoiding tape offset or twisting during the application process and improving the accuracy of the application.

[0051] Specifically, after the external tape is applied, the cardboard can be stopped from being conveyed so that the tape can be cut with a blade, or it can be cut while being conveyed to improve production efficiency.

[0052] Specifically, in this embodiment, the blade and the tape are arranged in a cross shape, and the end of the tape is set at an acute angle to the base surface of the frame 1.

[0053] Specifically, the origami module 3 includes an adsorption component 9 for limiting the cardboard and a third driving component 10 for driving the adsorption component 9 to reciprocate. The adsorption component 9 includes a telescopic rod, adsorption components 17 disposed on the telescopic rod, and a support plate for carrying the external cardboard. The support plate is located at the lower part of the adsorption component 9. The adsorption components 17 are used to cooperate with an external pump or vacuum generator to adsorb the cardboard. There are multiple adsorption components 17, and the multiple adsorption components 17 are arranged in an array. The telescopic rod in the adsorption component 9 and the adsorption components 17 disposed on it can accurately adsorb and fix the box, so that the box can maintain a stable position and posture during the origami process, avoiding forming errors caused by movement or displacement. The array of adsorption components 17 can provide a more uniform adsorption force, making the box more stable during movement, which helps to reduce forming failures or quality problems caused by vibration or external force interference.

[0054] Specifically, in this embodiment, the cardboard is conveyed to the carrier plate and then bent into shape by the adsorption component 9 set above the carrier plate. While the cardboard is being bent into shape by the adsorption component 9, or after it is bent into shape, the brush 4 is driven by the fourth driving component 29 to apply tape to the corners of the cardboard box. After the corners are applied, the cardboard box is taken out by the adsorption component 9. In this embodiment, the brush 4 applies the corners of the cardboard box during the process of the cardboard box being taken out by the adsorption component 9 and then transfers it to the discharge mechanism. Finally, the cardboard box is removed by the discharge mechanism.

[0055] Specifically, in this embodiment, four adsorption elements 17 are provided.

[0056] Specifically, the origami module 3 also includes a second frame 30 that is movably set relative to the frame 1. Two limiting members 13 are set on the second frame 30. The two limiting members 13 are used to limit the two ends of the cardboard that are far apart from each other. The two limiting members 13 limit the two sides of the box body respectively, ensuring the accurate positioning of the box body during the origami process. Precise limiting avoids forming errors caused by positional deviation, improves the forming accuracy of the product, and double-sided limiting can more comprehensively control the shape and position of the box body, making the box body more stable during the origami process and reducing forming failures or quality problems caused by vibration or external force interference.

[0057] Specifically, there are four second frames 30, and each second frame 30 is equipped with two limiting members 13. The two limiting members 13 are set perpendicularly to limit the two sides of the box.

[0058] Specifically, the bottom of the limiting member 13 is provided with an outwardly extending part, and the distance between the two extension parts is greater than the distance between the two limiting members 13. The extension part is used to guide the cardboard when it is adsorbed and lifted by the adsorption component 9, making the folding of the box smoother.

[0059] Specifically, the second frame 30 is also equipped with a fourth driving component 29. The brush 4 is located at the output end of the fourth driving component 29. The fourth driving component 29 is used to drive the brush 4 to contact the protruding end of the tape attached to the first side. The brush 4 evenly brushes the protruding end of the tape attached to the first side to the other side of the adjacent side, achieving perfect adhesion of the tape to the box. The brush 4, driven by the fourth driving component 29, can handle the tape more conveniently. The brush 4 is equipped with an array of bristles, so that the tape does not need to use hot melt adhesive or be heated. Ordinary tape can be used to complete the adhesion, reducing production costs and increasing production efficiency, and making the production process smoother and more efficient.

[0060] Specifically, the frame 1 is equipped with two limit plates 14, which are located on both sides of the width direction of the cardboard feeding mechanism 5 and the box ejection mechanism 6, respectively. The adjacent distance of the two limit plates 14 can be adjusted to guide the external cardboard / box. The limit plates 14 can accurately restrict the cardboard to the position to be conveyed, ensuring the positional stability of the cardboard during the conveying process. This helps to ensure that the subsequent glue application can be accurately aligned with one side of the box, improving the processing accuracy. By adjusting the adjacent distance of the limit plates 14, cardboard of different sizes and shapes can be accommodated, reducing the processing error caused by the cardboard position deviation. The limit plates 14 enable the equipment to continuously convey and process multiple cardboards without the need for frequent manual adjustment of the cardboard position, thus improving production efficiency.

[0061] Specifically, the frame 1 is also equipped with a first inductive switch 15, which is used to detect whether the cardboard is abnormal. The frame 1 is also equipped with a pressing assembly for use with the gluing mechanism. The pressing assembly has multiple rotatable wheels and an annular belt sleeved on the outside of the wheels. The pressing assembly ensures the cardboard is flat and positioned during the gluing process. The pressing assembly is adjustable on the frame 1. The first inductive switch 15 can detect whether materials overlap in real time. Once overlap is detected, an alarm signal is immediately triggered to stop operation, preventing overlapping materials from entering the processing area, thus avoiding product quality problems caused by overlapping processing. The real-time detection function of the first inductive switch 15 can immediately trigger a stop signal when materials overlap, reducing downtime caused by overlapping processing. Overlapping materials may damage the processing equipment, such as causing jamming or wear. The detection function of the first inductive switch 15 can prevent overlapping materials from entering the processing area, thereby protecting the equipment from damage and extending its service life.

[0062] Specifically, the adsorption assembly 9 includes a first plate 26 slidably mounted on a frame 1. A slide rail is also provided on the frame 1 to guide the first plate 26. A strip-shaped groove 16 is formed on the first plate 26. A telescopic rod is slidably mounted on the first plate 26 via the groove 16. There are two grooves 16, which are parallel to each other. Multiple adsorption elements 17 are provided, and the spacing between them is freely adjustable. The spacing between the multiple adsorption elements 17 can be adjusted by sliding the telescopic rod within the groove 16. This allows the adsorption assembly 9 to achieve optimal adsorption by adjusting the spacing of the adsorption elements, adapting to objects of different sizes. In this embodiment, the telescopic rod serves as an adjusting element, clamping the first plate 26 to fix / movably mount the multiple adsorption elements 17 onto the first plate 26. Other bolt-type components can also be used for this adjusting element, which will not be elaborated upon here.

[0063] Specifically, the frame 1 is provided with a first slide rail 27, and two second slide rails 28 are slidably arranged on the first slide rail 27. The second frame 30 is slidably arranged on the second slide rails 28. The second drive member 12 is used to drive the origami module 3 to move along the second slide rails in the X-axis direction. The frame is also provided with a fourth drive member, which is used to drive the two second slide rails to move along the first slide rail 27 in the Y-axis direction. By driving the second slide rails to move along the Y-axis direction on the first slide rails through the fourth drive member, and combined with the second drive member 12 driving the origami module to move along the X-axis direction on the second slide rails, the origami module can move freely in the two-dimensional plane, which greatly improves the flexibility of the origami module and enables it to perform more complex operation tasks.

[0064] Specifically, the frame 1 is equipped with end feet and wheels for use with the end feet. The end feet are equipped with telescopic components, which are used to adjust the distance between the frame 1 and the ground. By adjusting the telescopic components, the distance between the frame and the ground can be easily adjusted, so that it can adapt to ground environments with different heights and flatness. In uneven ground or scenarios that require stable support, adjusting the telescopic components can keep the frame in stable contact with the ground, which can significantly improve the overall stability of the equipment. When the machine needs to be moved, the manpower required for movement is reduced, the labor intensity is reduced, and the work efficiency is improved.

[0065] Specifically, the frame 1 is equipped with a base plate for use with the origami module 3. Located at the bottom of the origami module 3, the base plate serves as a stable platform to support the cardboard to be processed. This not only provides a stable working surface for the cardboard but also helps improve the accuracy and efficiency of the origami module 3 during the origami process. In particular, the base plate reduces the shaking and displacement of the cardboard during the origami process, making the operation of the origami module 3 more precise and thus reducing the possibility of deviations in the tape on the formed box.

[0066] Specifically, an automatic adhesive-applied box-making method includes the following steps:

[0067] S1: The cardboard feeding mechanism 5 is used to feed the cardboard to be folded into boxes one by one. The cardboard feeding mechanism can automatically and continuously feed the cardboard into the next process without manual placement, which greatly saves manpower and time. The driving component drives the limiting plate 14 to limit the board. The limiting plate 14 limits the cardboard according to the preset size and position, which reduces the cardboard size deviation or position error caused by improper stacking, thereby ensuring the product quality in subsequent processing. Through the limiting effect of the limiting plate, the risk of the cardboard falling due to unstable position during the conveying process can be reduced, thereby reducing the risk of accidents caused by the cardboard falling.

[0068] S2: The cardboard is fed to the gluing mechanism via the cardboard feeding mechanism 5 for gluing. The gluing mechanism is equipped with a rotating roller 25, which is used to press the adhesive tape supplied by the gluing mechanism onto the first side of the cardboard. The cardboard feeding mechanism 5 can ensure that the cardboard is accurately and stably delivered to the gluing mechanism, realizing continuous feeding and gluing of the cardboard, ensuring the continuity and stability of the production line. The cardboard is accurately fed to the gluing mechanism via the cardboard feeding mechanism 5. The guide roller 23 works in conjunction with the roller 25 to achieve precise bonding between the adhesive tape and the cardboard. Combined with the precision cutting of the blade and the first drive component, it not only greatly improves the accuracy and production efficiency of gluing, but also significantly ensures the consistency and durability of product quality. At the same time, it reduces labor and material costs and enhances the flexibility and market competitiveness of the production line.

[0069] S3: Cut the adhesive tape. The tape application mechanism is also equipped with a sensor to detect the length and position of the tape. The sensor is electrically connected to the central control component.

[0070] S4: The blade and the tape are set at an angle;

[0071] S5: The glued cardboard is sent to the forming mechanism for bending and shaping. The forming mechanism uses a folding module 3 to fold the cardboard into a box. The suction component 9, driven by the third drive component 10, allows the cardboard to be suctioned upwards. Combined with the precise drive of the second drive component 12 by the folding module 3, the cardboard is quickly and accurately bent into shape. This process not only improves production efficiency but also ensures the accuracy and consistency of box forming, further enhancing product quality and meeting market demands for high-quality packaging.

[0072] S6: The brush 4 configured in the adhesive applicator is used to apply the extended end of the tape on the first side of the bent box to the second side adjacent to the first side. After bending, the brush 4 is driven to apply the extended end of the tape on the first side of the bent box to the second side adjacent to the first side, so as to achieve perfect adhesion of the tape on the box. This reduces the need for manual adjustment of the tape position, reduces labor costs and the risk of human error, and at the same time makes the production process smoother and more efficient.

[0073] S7: The forming mechanism and brush 4 reset after completing their work;

[0074] S8: The box with the tape applied is removed via the ejector mechanism 6. The adsorption component 9 in the folding module 3 stably adsorbs and fixes the pre-formed box, which has already been tapered and is partially shaped. The third drive component then removes the box after tape application. The telescopic rod and the array of adsorption components 17 work together to ensure not only precise positioning and stable posture of the box during the folding process but also significantly reduce forming errors caused by movement or offset. Finally, this efficient and stable adsorption system allows for easy and accurate removal of the formed box. The entire process improves production efficiency and ensures the forming quality and consistency of the box.

For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
