Description

Technical Field

[0001] This utility model relates to the field of box gluing machines, and in particular to a fully automatic box gluing machine with tension adjustment. Background Technology

[0002] Fully automatic box gluing machines are equipment used in the packaging industry to automate processes such as folding, gluing, and pressing of paper box blanks. Models with tension adjustment functions adjust the material transmission tension in real time through sensors and a control system. This not only prevents deformation, wrinkles, or deviation caused by unstable tension during the transmission of paper jams and corrugated paper, ensuring the positioning accuracy of processes such as folding and gluing, but also allows for the processing of complex box shapes such as materials of different thicknesses and irregularly shaped boxes. During high-speed mass production, the scrap rate can be reduced from 5% to below 1%. At the same time, automatic parameter matching shortens the material changeover and debugging time to within 5 minutes. Its integrated closed-loop control and data access capabilities also support intelligent production, making it a key piece of equipment for improving packaging precision, efficiency, and flexible production capabilities.

[0003] Existing fully automatic carton gluing machines with tension adjustment are based on closed-loop control. By deploying strain gauge and magnetic powder tension sensors along the material conveying path, they collect material tension data in real time and transmit it to a PLC or industrial computer. The data is compared with preset target values ​​to calculate deviations. Once tension fluctuations occur, the system immediately drives the magnetic powder brake at the unwinding end, the servo motor at the conveying end, or the tension compensation roller and other actuators to dynamically adjust the unwinding resistance, conveyor belt speed, or roller pressure. This achieves an automated cycle of monitoring-feedback-adjustment. Some models are also equipped with adaptive algorithms and IoT functions, which can optimize parameters and provide remote warnings to ensure that the material tension is stable within 3%, thus guaranteeing the accuracy of carton forming and production efficiency.

[0004] However, in the actual application of fully automatic box gluing machines with tension adjustment, the equipment still suffers from the pain point of low specification switching efficiency. Although tension control has been automated, when producing paper boxes of different sizes, it is still necessary to manually change folding molds, adjust the pressure roller spacing, and reset mechanical parts such as conveyor belt guide rails. Taking the switching between 200mm×150mm and 300mm×200mm box types as an example, the operator needs to adjust 7 mechanical limit devices in sequence, which takes a long time. During this period, the equipment is in a stopped state. This mode of stopping the line when changing types causes the overall efficiency of the equipment to drop to below 60% when producing small batches of multiple specifications. Especially for industries such as cosmetics and electronic products that require frequent changes in packaging specifications, the time spent by the equipment in specification switching has become a key bottleneck restricting flexible production, so that the efficiency improvement brought by tension adjustment is offset by the inefficiency of mechanical type switching.

[0034] Each fixing component includes a fixing pin 10, a limiting plate 11, and multiple springs 12. The outer wall of the fixing pin 10 is slidably connected to the inside of the docking block 9 to fix the folding plate 13. The inner wall of the limiting plate 11 is fixedly connected to the outer wall of the fixing pin 10 to limit the movement range of the fixing pin 10. Each spring 12 is disposed inside the docking block 9 to provide elastic force to the fixing pin 10. One end of each spring 12 is fixedly connected to the inside of the docking block 9, and the other end of each spring 12 is fixedly connected to one side of the fixing pin 10. The dispensing component includes a support frame 4, a glue tank 5, and a glue sprayer 6.

The sealing component includes a fixing frame 18, a baffle 19, and The push plate 20 and the bottom of the fixing frame 2 18 are fixedly connected to the top of the base 1 to connect the baffle 19 and the push plate 20. The top of the baffle 19 is fixedly connected to the bottom of the fixing frame 2 18 to block the folded cardboard box. The top of the push plate 20 is fixedly connected to the bottom of the fixing frame 2 18 to push the last fold to seal the cardboard box. Each folding assembly includes multiple telescopic rods 14, fixing blocks 15, multiple extension rods 16 and a moving plate 17. The top of each telescopic rod 14 is fixedly connected to the bottom of the fixing frame 1 7 to adjust the height of the fixing blocks 15. The top of the fixing blocks 15 is fixedly connected to the bottom of the telescopic rods 14 to fix the position of the extension rods 16. One end of each extension rod 16 is fixedly connected to one side of the fixing blocks 15 to control the position of the moving plate 17. One side of the moving plate 17 is fixedly connected to one end of the extension rods 16 to fold the cardboard to form a cardboard box.

[0035] Specifically, when switching between different sized cardboard box folding operations, first activate the telescopic column 8 to raise it, slowly lifting the folding plate 13 to a height suitable for operation. Then, the operator holds the folding plate 13 with both hands and applies force to gently press it downwards. During this process, the inner wall of the folding plate 13 contacts the inclined surface of the fixing pin 10. As the pressure gradually increases, the fixing pin 10 slowly retracts into the docking block 9, successfully releasing the originally firmly fixed folding plate 13. At this point, the operator takes out the folding plate 13 that fits the new cardboard box size, aligns it with the docking block 9 at the bottom of the telescopic column 8, and gently pushes it in, so that the folding plate 13 and the telescopic column 8 are docked. After the fixing pin 10 pops out again under the elastic force of the spring 12 and embeds itself into the folding plate 13, the folding plate 13 replacement operation is completed. The whole process is smooth and seamless, laying the foundation for the smooth progress of subsequent cardboard box folding operations.

[0036] Reference Figure 4 and Figure 5Each movable plate 17 has multiple connecting slots 21 on one side for accommodating connecting blocks 23 and limiting blocks 24. Each movable plate 17 has a folding knife 22 slidably connected to one side for lifting and folding the cardboard. Each folding knife 22 has multiple connecting blocks 23 fixedly connected to one side for connecting the limiting blocks 24. Each connecting block 23 has a limiting block 24 fixedly connected to one side to limit the movement range of the folding knife 22. Each movable plate 17 has multiple fixed plates 25 slidably connected to one side for connecting handles 26 and connecting pins 27. Each fixed plate 25 has a handle 26 fixedly connected to one side for moving the connecting pins 27. Each fixed plate 25 has multiple connecting pins 27 fixedly connected to one side for fixing the limiting blocks 24 to fix the folding knife 22 to one side of the movable plate 17. The outer wall of each connecting pin 27 is slidably connected to the movable plate 17 and the limiting block 24.

[0037] Specifically, when the folding knife 22 needs to be replaced, the operator first places their palm on the handle 26 and pulls it outward smoothly. As the arm muscles tighten, the engagement between the connecting pin 27 and the limiting block 24 is broken, and the cylindrical connecting pin 27 slowly comes out of the groove inside the limiting block 24, successfully releasing the locking state of the limiting block 24. Next, the operator uses their other hand to firmly support the folding knife 22 and, following the guide of the connecting groove 21, slowly pushes the folding knife 22 upward, causing the limiting block 24 to gradually come out along the deepest part of the connecting groove 21. When the folding knife 22 is raised to a specific height and completely separated from the positioning latch of the moving plate 17, the operator pulls it outward with a little force, and the folding knife 22 is smoothly pulled out from inside the moving plate 17. The entire disassembly process is completed in one go, revealing the precise fit of the mechanical structure, which prepares for the subsequent installation of a folding knife 22 adapted to the new specifications.

[0038] Working Principle: In the process of using the fully automatic gluing machine with tension adjustment, the cardboard is first placed on conveyor belt 2. Then, the conveyor belt 2 is started to move the cardboard to the glue sprayer 6 for glue spraying. Afterward, the cardboard moves below the folding plate 13. The telescopic rod 14 is activated, causing the fixing block 15 to move downward. Then, the extension rod 16 is activated, causing the folding knife 22 to lift the cardboard and fold it using the moving plate 17. Next, the telescopic column 8 is activated to lift the folding plate 13, while the telescopic rod 14 and the extension rod 16 work together to lift the folding knife 22. Then, the conveyor belt 2 is activated to transport the folded cardboard to the front of the baffle 19. Finally, the push plate 20 is activated to seal the cardboard. When different sizes of cardboard need to be folded... First, activate the telescopic column 8 to raise the height of the folding plate 13. Then, grasp the folding plate 13 and move it downwards to make the inner wall of the folding plate 13 press against the fixing pin 10 and retract it into the docking block 9 to unlock the folding plate 13. After that, install the folding plate 13 of the corresponding size to be used at the bottom of the telescopic column 8. When it is necessary to replace the folding knife 22, first grasp the handle 26 and pull it outwards to make the connecting pin 27 disengage from the limit block 24 to unlock the limit block 24. Then, grasp the folding knife 22 and move it upwards to make the limit block 24 disengage from the deepest part of the connecting groove 21. After raising it to a certain height, pull the folding knife 22 outwards to remove the folding knife 22 from the moving plate 17.
