Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box processing, and in particular to an automatic folding and forming device for corrugated cardboard boxes. Background Technology

[0002] Automatic folding and forming devices for corrugated boxes on the market are key equipment in the large-scale production of corrugated boxes. They can automatically complete the folding, forming and pre-fixing of the die-cut and creasing corrugated cardboard, output a regular three-dimensional box shape and connect to subsequent sealing and other processes. The core advantages are that they can greatly improve production efficiency, ensure folding accuracy and box shape consistency, while reducing labor costs, labor intensity and raw material loss. They can also flexibly adapt to multiple specifications of cardboard boxes, helping the production line to achieve automation and intelligent upgrades. The automatic folding and forming devices for corrugated cardboard boxes on the market are mainly composed of three modules: mechanical execution, automatic control, and auxiliary support. The mechanical execution module includes key components such as material feeding and conveying, folding and forming, positioning and clamping, and material discharge and conveying. The automatic control module is based on a PLC, and is equipped with a human-machine interface, sensor components, and drive components. The auxiliary support module covers components such as frame support, safety protection, lubrication and heat dissipation. All parts work together to achieve precise automatic folding and forming of cardboard boxes. The drawback of some commercially available automatic folding and forming devices for corrugated boxes is that their dimensions are fixed and cannot be adjusted. The corrugated boxes produced can only be of a fixed size. When it is necessary to produce boxes of other specifications and sizes, corresponding equipment must be purchased separately. Therefore, an automatic folding and forming device for corrugated boxes is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an automatic folding and forming device for corrugated cardboard boxes, which aims to improve the problem that in the prior art, a single machine can only produce corrugated cardboard boxes of one size.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic folding and forming device for corrugated cardboard boxes includes a support base, an adjustment mechanism fixedly connected to the inner side of the support base, a support frame fixedly connected to the top of the support base, and a replacement mechanism installed on the top of the support frame.

As a further description of the above technical solution: The sliding assembly includes a connecting post, which is rotatably connected to the end of the push arm rod away from the connecting block. A sliding block is fixedly connected to the top of the connecting post, and a limiting piece is fixedly connected to the bottom of the connecting post. As a further description of the above technical solution: An operating plate is fixedly connected to the outside of the sliding block. A connecting plate is slidably connected to the right end of the operating plate. A cylinder is installed at the bottom of the connecting plate. The driving end of the cylinder is fixedly connected to the right end of the connecting rod. As a further description of the above technical solution: The sliding block is internally slidably connected to a slide rail column, and the outer end of the slide rail column is fixedly connected to the inner side of the support base. As a further description of the above technical solution: A gasket is fixedly connected to the outside of the sliding column, and the outside of the gasket is slidably connected to the inside of the push-lock column.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the width adjustment mechanism uses a cylinder as a power source. Its linear motion drives the connecting rod to rotate, which in turn pushes the connecting block to move. The connecting block then drives the push arm to swing, and the push arm transmits the thrust to the connecting column, causing the sliding block to slide along the slide rail column, thereby driving the operating panel to complete the width adjustment. This design uses a cylinder as the core and transmits power layer by layer through the connecting rod and push arm structure, achieving smooth and precise size customization. The support column provides stable support for the connecting rod, the slide rail column ensures that the sliding direction is controllable, and the limit plate prevents the components from dislodging, making the adjustment process simple and reliable. Users can quickly complete the width change without complicated operations, improving the adaptability and ease of use of the equipment.

[0006] 2. In this utility model, the pressure plate replacement mechanism uses a push plate as a trigger structure. When pressed, it drives the sliding column to slide inside the push pin. The sliding column pushes the pad to compress the return spring and further pushes the movable pin to separate from the push pin, releasing the locking ball to replace the pressure plate. After replacement, the push plate is released, and the rebound force of the return spring drives the sliding column to reset. The sliding column then drives the movable pin to close with the push pin, fixing the locking ball and the pressure plate. This structure, which uses a push plate to drive the sliding column and a spring to control the buckle, realizes the quick disassembly and assembly of the pressure plate, significantly reduces downtime, improves maintenance efficiency, and is simple, secure, and reliable to operate.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0010] Automatic folding and forming device for corrugated cardboard boxes, refer to Figures 1 to 3 The device includes a support base 6, an adjustment mechanism 3 is fixedly connected to the inner side of the support base 6, a support frame 5 is fixedly connected to the top of the support base 6, and a replacement mechanism 4 is installed on the top of the support frame 5. The support base 6 provides a stable bearing foundation for the entire device. The adjustment mechanism 3 is adapted to the folding requirements of different sized cartons. The support frame 5 provides reliable installation support for the replacement mechanism 4. The replacement mechanism 4 ensures the rapid replacement of the folding components. Specifically, the support base 6, as the core of the overall load-bearing structure, provides solid support through its stable and close-fitting bottom design, ensuring that the device operates without shaking or shifting. The adjustment mechanism 3, fixed inside, uses the telescopic rod to extend and slide along the slide rail to achieve fine-tuning of the spacing, flexibly adapting to the folding processing needs of cartons of different lengths and widths. The support frame 5 on the top of the support base 6 adopts a frame structure, which provides horizontal positioning and load-bearing support for the replacement mechanism 4, and ensures the coaxiality of the components after installation. The replacement mechanism 4 uses a snap-fit ​​connection and guide groove to achieve quick disassembly and replacement of the folding mold, reducing the time spent on mold changeover. All structures work together to form a complete operation chain, improving the efficiency and adaptability of folding forming.

[0011] The adjustment mechanism 3 includes a support column 34, the outer end of which is fixedly connected to the inner side of the support base 6. A connecting rod 33 is slidably connected inside the support column 34. A connecting block 32 is fixedly connected to the outside of the connecting rod 33. A push arm rod 35 is rotatably connected to the outside of the connecting block 32. A sliding component 37 is rotatably connected to the end of the push arm rod 35 away from the connecting block 32. The support column 34 restricts the sliding direction of the connecting rod 33. The connecting rod 33 efficiently transmits power. The connecting block 32 realizes the flexible connection between the connecting rod 33 and the push arm rod 35. The push arm rod 35 directionally transmits power to the sliding component 37. Specifically, the adjustment mechanism 3 of the automatic folding and forming device is structurally designed to meet the folding adaptation requirements. The outer end of the support column 34 is firmly fixed to the inner side of the support base 6, which not only serves as a structural fixation function, but also precisely limits the sliding direction of the connecting rod 33 to avoid deviation and ensure motion accuracy. The connecting rod 33 slides smoothly inside the support column 34, which can efficiently transmit the adjustment driving force and build a key bridge for power transmission. The connecting block 32 is fixed to the outside of the connecting rod 33. By rotating the connecting structure, the push arm 35 can swing flexibly to achieve a clever conversion of the power direction. The end of the push arm 35 away from the connecting block 32 is rotatably connected to the sliding component 37, which converts the linear sliding of the connecting rod 33 into the directional displacement of the sliding component 37, thereby adapting to the folding position requirements of different sized cartons. The linkage of each component ensures the flexibility and accuracy of adjustment.

[0012] The sliding assembly 37 includes a connecting post 373, which is externally rotatably connected to the end of the push arm 35 away from the connecting block 32. A sliding block 371 is fixedly connected to the top of the connecting post 373, and a limiting piece 372 is fixedly connected to the bottom of the connecting post 373. The connecting post 373 receives the power of the push arm 35 and transmits it to the sliding block 371. The sliding block 371 drives the subsequent components to move synchronously. The limiting piece 372 prevents the push arm 35 from disengaging from the connecting post 373. Specifically, the sliding component 37 of the adjustment mechanism 3 is designed around power transmission and stable sliding. The connecting column 373 flexibly receives the swinging power of the push arm 35 away from the connecting block 32 through a rotational connection. Its rotatable characteristics allow the movement direction of the push arm 35 to smoothly adapt to subsequent transmission requirements, while accurately transmitting power to the upper and lower connected components. The top-fixed sliding block 371 slides smoothly along the device's preset slide rail, synchronously displacing the relevant folding edge actuators to ensure that the folding edge position is accurately adjusted. The bottom limiting piece 372 fits tightly against the bottom end of the connecting column 373, forming an axial limit, effectively preventing the push arm 35 from detaching from the connecting column 373 during swinging. Through the cooperation of fixing and rotation, the components achieve synergy in power transmission, directional sliding, and structural anti-detachment, ensuring the stability of the sliding component 37's movement and the accuracy of the folding edge adjustment.

[0013] The sliding block 371 is externally fixedly connected to the operating plate 2. The right end of the operating plate 2 is slidably connected to the connecting plate 1. The bottom of the connecting plate 1 is equipped with a cylinder 31. The driving end of the cylinder 31 is fixedly connected to the right end of the connecting rod 33. The operating plate 2 is the core execution component of the folded forming. The connecting plate 1 provides a stable mounting point for the cylinder 31. The cylinder 31 provides the core driving force for the adjustment mechanism 3. The sliding block 371 is internally slidably connected to the slide rail column 36. The outer end of the slide rail column 36 is fixedly connected to the inner side of the support base 6. The slide rail column 36 provides a precise sliding trajectory for the sliding block 371, ensuring that the operation plate 2 moves smoothly without deviation. Specifically, the sliding block 371 is securely connected to the operating plate 2. As the core execution component for folding and forming, the operating plate 2 will move synchronously with the sliding block 371 to complete the folding operation. Its right end is slidably connected to the connecting plate 1. The connecting plate 1 provides a stable support point for the cylinder 31 installed at the bottom and ensures the coordination of component movement through sliding adaptation. The cylinder 31, as the core power source of the adjustment mechanism 3, has its drive end fixed to the right end of the connecting rod 33 and can output a smooth linear driving force to drive the connecting rod 33 to slide. The sliding block 371 is fitted with a slide rail column 36 inside. The outer end of the slide rail column 36 is fixed to the inner side of the support base 6, providing a precise guide trajectory for the sliding block 371, limiting its sliding direction, ensuring that the operating plate 2 moves smoothly without deviation, and ensuring the folding accuracy and adjustment stability.

[0014] Reference Figure 1 , Figure 2 and Figure 4 The replacement mechanism 4 includes a push cylinder 41, which is mounted on the top of the support frame 5. The drive end of the push cylinder 41 is fixedly connected to a push pin 42. The push cylinder 41 provides an installation carrier and auxiliary support for the replacement mechanism 4. The push pin 42 is the core basic component for locking and fixing. A sliding column 44 is slidably connected inside the push pin 42. A return spring 46 is sleeved on the outside of the sliding column 44. The left end of the return spring 46 abuts against the inside of the push pin 42. The sliding column 44 can slide flexibly inside the push pin 42. The return spring 46 provides elastic support for component reset. Specifically, the automatic hemming forming device's replacement mechanism 4 focuses on the rapid replacement design of hemming components. The push cylinder 41 is firmly installed on the top of the support frame 5, which not only provides installation positioning and load-bearing support for the entire mechanism, but also outputs axial driving force to directly drive the push pin 42 at the drive end to perform telescopic movement. The push pin 42 serves as the locking and fixing core, and achieves precise docking with the hemming component through its own displacement. The reserved sliding channel inside allows the sliding column 44 to slide flexibly back and forth, adapting to the locking and unlocking action requirements. The left end of the externally sleeved return spring 46 tightly abuts against the inner wall of the push pin 42. When the locking action is completed or unlocking is required, the return spring 46 pushes the sliding column 44 to reset through elastic rebound, ensuring the efficiency and stability of hemming component replacement.

[0015] A pusher plate 43 is fixedly connected to the right end of the sliding column 44, and a washer 45 is fixedly connected to the outside of the sliding column 44. The right end of the return spring 46 abuts against the left side of the washer 45. The pusher plate 43 facilitates manual triggering of the sliding column 44. The washer 45 can evenly transmit pressure to the return spring 46 to avoid uneven local force. The outside of the washer 45 is slidably connected to the inside of the push pin 42. A movable pin 47 is fixedly connected to the left end of the sliding column 44. The outside of the movable pin 47 is slidably connected to the bottom of the push pin 42. The washer 45 slides smoothly inside the push pin 42. The movable pin 47 and the push pin 42 cooperate to lock and release the ball 48. Specifically, the pusher plate 43 fixed to the right end of the sliding column 44 of the replacement mechanism 4 provides a convenient trigger point for manual operation. When pressed, it can directly drive the sliding column 44 to slide smoothly along the inside of the push pin 42. The pad 45 on the outside of the sliding column 44 slides against the inner wall of the push pin 42, which can not only evenly transmit the pressing force to the return spring 46 on the right side to avoid deformation caused by uneven local force, but also squeeze the return spring 46 to produce elastic deformation as the sliding column 44 moves synchronously. The movable pin 47 at the left end of the sliding column 44 slides at the bottom of the push pin 42. When the sliding column 44 moves left and right, the movable pin 47 moves in conjunction with it. Through cooperation with the push pin 42, it locks or unlocks the ball 48. After releasing the pusher plate 43, the return spring 46 elastically rebounds and pushes the pad 45 and the sliding column 44 to reset, allowing the movable pin 47 to relock the ball 48, ensuring smooth engagement and replacement.

[0016] The push post 42 is slidably connected to the inside of the push post 42. The left side of the push post 48 is slidably connected to the inside of the movable push post 47. The bottom of the push post 48 is fixedly connected to the pressure plate 49. The push post 48 serves as a connecting hub to achieve a stable connection between the push post 42 and the pressure plate 49. The pressure plate 49 directly acts on the folding and forming operation of the corrugated cardboard box. Specifically, the push pin 42 of the replacement mechanism 4 has a flexible sliding ball 48 inside. Its left side precisely matches and slides with the inner wall of the movable pin 47. When the movable pin 47 moves left or right, it locks or unlocks the ball 48 through the inner wall contact, making the ball 48 a key hub for connection and transmission. The bottom of the ball 48 is firmly fixed to the pressure plate 49, which can transmit the driving force of the push pin 42 and the locking force of the movable pin 47 to the pressure plate 49 simultaneously. It can also adjust the force of the folding operation through its own sliding. The pressure plate 49 keeps a horizontal and flat state and directly adheres to the part of the corrugated carton to be folded. Under the linkage of the ball 48, pressure is precisely applied, and the operation plate 2 completes the folding shape, ensuring the stability of the connection and the accuracy of the folding.

[0017] The implementation principle of this application embodiment is as follows: When the user needs to adjust the size, the cylinder 31 is activated. The cylinder 31 pushes the connecting rod 33, which in turn drives the connecting block 32 to push the push arm 35. The push arm 35 transmits the thrust of the cylinder 31 to the connecting column 373. When the connecting column 373 is pushed by the push arm 35, it drives the sliding block 371 to slide on the slide rail column 36 towards the support seat 6. The sliding component 37 then drives the operation plate 2 to complete the width adjustment. The components on the operation plate 2 can also be adjusted to complete the size change. When the cylinder 31 retracts, it drives the sliding block 371 to slide inward through the connecting rod 33, connecting block 32, push arm 35 and connecting column 373 to shorten the width. The limiting piece 372 prevents the outer end of the push arm 35 from disengaging downward from the connecting column 373. The support column 34 provides support for the connecting rod 33. The slide rail column 36 stops the sliding track and direction. This allows for customized adjustment of the width, which is convenient and simple. After the width adjustment is complete, press the actuating piece 43. The actuating piece 43 will push the sliding post 44 to slide inside the push post 42. The sliding post 44 will drive the washer 45 to squeeze the return spring 46 inside the push post 42. The sliding post 44 will pass through the push post 42 and push the movable post 47. After the movable post 47 and the push post 42 separate, the locking ball 48 will disengage. At this time, replace the new pressure plate 49, put the locking ball 48 between the push post 42 and the movable post 47, release the actuating piece 43, and the return spring 46 will rebound and push the component to reset, so that the movable post 47 and the push post 42 complete the closure, thereby fixing the locking ball 48 and the pressure plate 49, completing the quick replacement of the pressure plate 49 and reducing downtime.
