Description

Technical Field

[0001] This utility model relates to the field of flipping machine technology, and in particular to a flipping machine for corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a type of sheet material composed of multiple layers of paper. It possesses strong compressive strength and good toughness, and is widely used in the packaging industry. The main structure of its flipping machine includes a frame, side platform, cylinder, push shaft, cross rail, slide table, rack, pinion, rotating shaft, and clamping components. Driven by the cylinder, the push shaft moves the slide table along the cross rail. The rack and pinion on the slide table mesh, and the rotating shaft drives the clamping components to flip the corrugated cardboard, thus achieving the flipping operation. Each component works in concert to ensure the stability and accuracy of the corrugated cardboard flipping.

[0003] A traditional cardboard flipping machine typically consists of a fixed frame, a support platform, a pneumatic system, a slide rail, a slide table, a rack and pinion mechanism, and a flipping mechanism. A cylinder provides power, driving the slide table along the horizontal rail via a push shaft. The rack and pinion on the slide table mesh, and the rotation of the pinion drives the rotating shaft, thus driving the clamping assembly to flip the cardboard. The design and configuration of each component determine the working efficiency and accuracy of the flipping machine.

[0004] Traditional cardboard flipping machines have low flipping efficiency, primarily due to friction in their moving parts and insufficient meshing precision between the rack and pinion teeth. This generates resistance during movement, increasing the time required for flipping. Furthermore, traditional designs often lack sufficient adjustment and automation functions, requiring significant manual intervention during operation, increasing labor costs and time consumption, and impacting production efficiency. Therefore, the low efficiency of flipping machines directly affects the overall production progress and economic benefits of cardboard processing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a corrugated cardboard flipping machine, which aims to improve the problem that the traditional cardboard flipping machine has low flipping efficiency, increases labor costs and time consumption, and affects production efficiency.

[0007] The flip-plate assembly includes a horizontal rail, the sidewall of which is fixedly connected to the sidewall of the side platform. A slide is slidably connected to the sidewall of the horizontal rail, and a rack is fixedly connected to the lower surface of the slide. Multiple fixed platforms are fixedly connected to the sidewall of the side platform, and multiple toothed columns are rotatably connected to the sidewall of the side platform. Each toothed column meshes with the rack, and a rotating shaft is fixedly connected to the sidewall of each toothed column. Each rotating shaft is rotatably connected inside the fixed platform, and a clamping assembly is provided at one end of the rotating shaft.

[0013] Each gear has a fixed shaft fixedly connected inside, and a rotating plate is fixedly connected to the outer wall of the fixed shaft.

[0014] As a further description of the above technical solution:

[0015] One end of the output shaft is rotatably connected to the side wall of the rotating plate, and multiple connecting shafts are fixedly connected inside the clamping platform.

[0016] As a further description of the above technical solution:

[0035] Reference Figures 1-3This utility model provides an embodiment of a corrugated cardboard flipping machine, including a frame 1. A side platform 2 is fixedly connected to the side wall of the frame 1, providing stable support and ensuring the structural stability of the entire flipping machine. A cylinder 3 is fixedly connected to the side wall of the side platform 2, providing driving force pneumatically. A push shaft 4 is rotatably connected to the output end of the cylinder 3, which transmits the power of the cylinder 3 to the flipping assembly to execute the flipping action. A flipping assembly is provided on the side wall of the side platform 2. The flipping assembly includes a horizontal rail 5, which is fixedly connected to the side wall of the side platform 2, providing guidance and support for the sliding of a slide table 6. The slide table 6 is slidably connected to the side wall of the horizontal rail 5, allowing it to slide smoothly along the horizontal rail 5 and ensuring the accuracy of the flipping action. A rack 7 is fixedly connected to the lower surface of the slide table 6, meshing with a toothed column 8 to guide the vertical movement of the slide table 6. Linear motion is converted into rotational motion of the toothed column 8. The stable connection of the rack 7 ensures smooth flipping. Multiple fixed platforms 9 are fixedly connected to the side wall of the side platform 2. The fixed platforms 9 provide support for the rotating shaft 10, ensuring the stability and rotational accuracy of the rotating shaft 10. Multiple toothed columns 8 are rotatably connected to the side wall of the side platform 2. Each toothed column 8 meshes with the rack 7. The rotation of the toothed column 8 ensures the orderly operation of the flipping action. Each toothed column 8 is fixedly connected to the side wall of the rotating shaft 10. The rotating shaft 10 achieves the flipping action of the clamping component by rotation. The rotating shaft 10 is rotatably connected inside the fixed platform 9. The fixed platform 9 provides rotational support for the rotating shaft 10, enabling the flipping action to proceed smoothly. A clamping component is set at one end of the rotating shaft 10 to clamp and flip the corrugated cardboard, ensuring the accuracy and stability of the corrugated cardboard flipping, thereby completing the flipping operation.

[0036] Reference Figure 4 and Figure 5 The clamping assembly includes a clamping platform 11, with multiple gears 13 rotatably connected inside the clamping platform 11. An electric push rod 12 is fixedly connected inside the clamping platform 11, and an output shaft 21 is fixedly connected to the output end of the electric push rod 12. A fixed shaft 14 is fixedly connected inside each gear 13, and a rotating plate 15 is fixedly connected to the outer wall of the fixed shaft 14. One end of the output shaft 21 is rotatably connected to the side wall of the rotating plate 15. Multiple connecting shafts 17 are fixedly connected inside the clamping platform 11, and a turntable 18 is rotatably connected to the outer wall of each connecting shaft 17. A base plate 19 is fixedly connected to the bottom of each turntable 18, and a connecting rod 16 is rotatably connected to the side wall of each base plate 19. The other end of the connecting rod 16 is rotatably connected to the side wall of the rotating plate 15. A clamping plate 20 is fixedly connected to the side wall of each turntable 18.

[0037] Working principle: When the corrugated cardboard needs to be flipped, cylinder 3 is activated, and its output end pushes the push shaft 4 to move horizontally, causing the slide table 6 to slide along the horizontal rail 5. The rack 7 on the lower surface of the slide table 6 meshes with the toothed column 8, converting the linear motion into the rotational motion of the toothed column 8, which in turn drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the clamping assembly to rotate as a whole. When the cylinder 3 extends, the rack 7 drives the toothed column 8 to rotate clockwise, causing the clamping assembly to rotate 180° clockwise. When the cylinder 3 retracts, the toothed column 8 reverses, and the clamping assembly resets counterclockwise, realizing the flipping action of the corrugated cardboard. After the electric push rod 12 is started, the output shaft 21 pushes the rotating plate 15 to rotate around the fixed shaft 14. The rotating plate 15 pulls the turntable 18 to swing on the connecting shaft 17 through the connecting rod 16, causing the clamping plate 20 to open or close. When the output shaft 21 extends, the rotating plate 15 drives the connecting rod 16 to move downward, and the turntable 18 drives the clamping plate 20 to clamp the corrugated cardboard. When the output shaft 21 retracts, the clamping plate 20 is released. At the same time, the rotation of the rotating plate 15 drives the gear 13 to rotate synchronously through the fixed shaft 14, ensuring that the multiple clamping plates 20 move in unison and preventing the cardboard from shifting during clamping.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
