[0002] In the traditional production process of the cardboard packaging industry, the folding operation of cardboard box forming machines has always been a key factor affecting production efficiency and product quality. Traditional folding mechanism designs often rely on manual adjustment or simple mechanized devices, which not only limits the automation level of the production line but also leads to low operational efficiency. Manual adjustment requires operators to have a high level of skill, and the adjustment process is time-consuming and labor-intensive, easily introducing errors due to human factors, affecting the accuracy and consistency of the cardboard box folds. Meanwhile, simple mechanized devices, lacking sufficient flexibility and precision, often struggle to adapt to the diverse and personalized cardboard box demands of the market, limiting the application range of cardboard box forming machines.
[0003] Furthermore, traditional folding mechanisms are prone to decreased precision and frequent malfunctions during long-term operation due to wear and aging, further impacting production efficiency and product quality. Therefore, the market urgently needs a folding mechanism for carton forming machines that can overcome these shortcomings and achieve efficient, precise, and automated folding operations to improve the overall performance and competitiveness of the production line.
[0004] Furthermore, the replacement and maintenance of the connecting rod in the existing folding mechanism of cardboard box forming machines has always been a major problem for users. Due to design deficiencies, the connecting rod is often difficult to disassemble and replace quickly and conveniently, resulting in high maintenance costs and time-consuming processes. This not only increases the operating costs of enterprises but also affects the reliability and durability of the equipment. To address this, we provide a folding mechanism for cardboard box forming machines. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a folding lug mechanism for a paper box forming machine, which more accurately solves the problems mentioned in the background art.
[0006] This utility model is achieved through the following technical solution:
[0007] This utility model discloses a folding mechanism for a cardboard box forming machine, including a worktable. A first guide groove is formed on the surface of the worktable, and an I-shaped slider is slidably connected to the inner wall of the first guide groove. A clamping rod is fixedly connected to the upper surface of the I-shaped slider, and cardboard is clamped between the two clamping rods. A second guide groove is formed on the surface of the worktable, and an I-shaped slider is slidably connected to the inner wall of the second guide groove. A connecting rod is installed at the upper end of the I-shaped slider for moving and bending the cardboard. A pushing structure connects the worktable and the I-shaped slider. An adjustment mechanism for adjusting the clamping distance of the two clamping rods is connected between the worktable and the I-shaped slider. A replacement assembly connects the I-shaped slider and the connecting rod.
[0008] The adjustment mechanism includes a servo motor fixedly installed on the lower surface of the workbench. The output end of the servo motor is fixedly connected to a pulley one. The inside of the guide groove one is rotatably connected to a threaded rod through a bearing. The I-shaped slider one is threadedly sleeved on the outside of the threaded rod. The end of the threaded rod is fixedly connected to a pulley two. A linkage belt is wound around the outside of the pulley one and the pulley two.
[0009] Furthermore, the replacement assembly includes a limiting plate fixedly installed on the upper surface of the I-shaped slider II. A vertical rod is fixedly connected to the upper surface of the limiting plate, and the sleeve rod is sleeved around the vertical rod. An end cap is installed at the upper end of the vertical rod, and a disassembly and assembly component is connected between the end cap and the vertical rod.
[0010] Furthermore, the pushing structure includes a hydraulic cylinder fixedly installed on the lower surface of the worktable and a connecting block fixedly connected to the lower surface of the I-shaped slider, and the output end of the hydraulic cylinder is fixedly connected to the surface of the connecting block.
[0011] Furthermore, the disassembly and assembly components include an end cap sleeved around the upper periphery of the upright rod and a threaded hole opened on the upper surface of the upright rod. The upper end of the end cap has a mounting groove, and a torque screw is placed inside the mounting groove. The threaded section of the torque screw is threadedly connected to the inner wall of the threaded hole.
[0012] Furthermore, the first belt pulley has a double-groove design, and the second belt pulley has a single-groove design, which is used for the first belt pulley to work with the linkage belt to synchronously drive the two second belt pulleys to rotate.
[0013] Furthermore, the outer threads of the threaded rod are designed in opposite directions, so that the two outer I-shaped sliders move in opposite or relative directions during rotation.
[0014] The beneficial effects of this utility model are:
[0015] This invention, through the design of an adjustment mechanism and a pushing structure, enables efficient clamping and bending of cardboard. The adjustment mechanism, utilizing a servo motor, pulley, threaded rod, and I-shaped slider, can precisely adjust the clamping distance between the two clamping rods to accommodate cardboard of different sizes. Simultaneously, the pushing structure, through the telescopic movement of a hydraulic cylinder, pushes the I-shaped slider along the guide groove, thereby moving the connecting rod and realizing the bending operation of the cardboard. This design not only improves work efficiency but also ensures the accuracy and stability of cardboard bending.
[0016] This utility model incorporates a replacement assembly, including a limiting plate, a support rod, an end cap, and disassembly / removal components. The connecting rod is sleeved around the support rod, and its secure connection is achieved through the end cap and disassembly / removal components.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details. Example
[0023] like Figures 1-4As shown in the figure, an embodiment of the present invention discloses a folding mechanism for a cardboard box forming machine, including a worktable 1. A guide groove 2 is formed on the surface of the worktable 1, and an I-shaped slider 3 is slidably connected to the inner wall of the guide groove 2. A clamping rod 4 is fixedly connected to the upper surface of the I-shaped slider 3, and the two clamping rods 4 are used to clamp the cardboard 5. A second guide groove 6 is also formed on the surface of the worktable 1, and an I-shaped slider 7 is slidably connected to the inner wall of the second guide groove 6. A connecting rod 8 is installed at the upper end of the I-shaped slider 7, and the connecting rod 8 is used to move and bend the cardboard 5. The worktable 1 and the I-shaped slider 7 are connected by a pushing structure, which includes a hydraulic cylinder 9 fixedly installed on the lower surface of the worktable 1 and a connecting block 10 fixedly connected to the lower surface of the I-shaped slider 7. The output end of the hydraulic cylinder 9 is fixedly connected to the surface of the connecting block 10. Through the extension and retraction of the hydraulic cylinder 9, the I-shaped slider 7 can be pushed to slide along the guide groove 6.
[0024] The worktable 1 and the I-shaped slider 3 are connected by an adjustment mechanism. This mechanism includes a servo motor 11 fixedly mounted on the lower surface of the worktable 1. A pulley 12 is fixedly connected to the output end of the servo motor 11. A threaded rod 13 is rotatably connected to the inside of the guide groove 2 via bearings, and the I-shaped slider 3 is threadedly fitted around the threaded rod 13. A second pulley 14 is fixedly connected to the end of the threaded rod 13, and a linkage belt 15 is wound around the outer periphery of both pulleys 12 and 14. When the servo motor 11 starts, it drives the second pulley 14 and the threaded rod 13 to rotate via the pulley 12 and linkage belt 15, thereby moving the I-shaped slider 3 along the threaded rod 13 and adjusting the clamping distance between the two clamping rods 4. This structure enables the clamping and bending of the cardboard 5, and the clamping distance is adjustable to accommodate cardboard of different sizes.
[0025] Furthermore, the replacement assembly includes a limiting plate 16 fixedly installed on the upper surface of the I-shaped slider 7. A retaining rod 17 is fixedly connected to the upper surface of the limiting plate 16, and a connecting rod 8 is sleeved around the retaining rod 17 to achieve sliding and fixing of the connecting rod 8. An end cap 18 is installed at the upper end of the retaining rod 17, and the end cap 18 is connected to the retaining rod 17 through a disassembly and assembly component. By replacing the assembly, the connecting rod 8 can be easily replaced to adapt to the bending requirements of cardboard of different shapes and sizes.
[0026] Furthermore, the specific implementation of the pushing structure has been described in detail in the implementation method. That is, by the extension and retraction of the hydraulic cylinder 9, the I-shaped slider 7 is pushed to slide along the guide groove 6, thereby driving the sleeve rod 8 to move and realize the bending operation of the cardboard. The pushing structure is stable and reliable and can accurately control the moving position and speed of the sleeve rod 8.
[0027] Furthermore, the disassembly and assembly components include an end cap 18 that fits around the upper periphery of the upright rod 17 and a threaded hole 19 formed on the upper surface of the upright rod 17. The upper end of the end cap 18 has a mounting groove 20, inside which a torque screw 21 is placed, and the threaded section of the torque screw 21 is threaded into the inner wall of the threaded hole 19. By rotating the torque screw 21, it can be tightened or loosened, thereby achieving the fixing or disassembly of the end cap 18 and the upright rod 17. The disassembly and assembly components are ingeniously designed, easy to operate, and allow for quick replacement of the connecting rod 8.
[0028] Furthermore, belt pulley 12 has a double-groove design, while belt pulley 14 has a single-groove design. When the servo motor 11 starts, belt pulley 12 synchronously drives the two belt pulleys 14 to rotate via the linkage belt 15, thereby driving the two threaded rods 13 to rotate synchronously. Since the outer threads of the threaded rods 13 are designed in opposite directions, when the threaded rods 13 rotate, the two outer I-shaped sliders 3 will move in opposite directions or relative to each other, thereby adjusting the clamping distance between the two clamping rods 4. The adjustment mechanism is reasonably designed and can accurately control the size of the clamping distance to adapt to different sizes of cardboard.
[0029] Furthermore, the outer threads of the threaded rod 13 are designed in opposite directions, as described in detail in the embodiments. When the threaded rod 13 rotates, due to the opposite thread design, the two outer I-shaped sliders 3 will move in opposite directions or relative to each other, thereby adjusting the clamping distance between the two clamping rods 4; the opposite thread design of the threaded rod 13 enables the adjusting mechanism to adjust the position of the two I-shaped sliders 3 simultaneously, improving work efficiency and accuracy.
