DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Example 1: Refer to Figures 1-4, A creasing device for composite cardboard production, including a base 11. A first side plate 1 is fixedly connected to the base 11. A telescopic rod 6 is connected to the first side plate 1 through a moving mechanism. The moving mechanism includes a motor 2. A first threaded rod 3 is drivably connected to the output shaft of the motor 2. A moving block 5 is threadedly penetrated through the first threaded rod 3. The moving block 5 is fixedly connected to the telescopic rod 6. The moving block 5 is limited by a limiting mechanism. By rotating the motor 2, the first threaded rod 3 is driven to rotate, thereby adjusting the position of the moving block 5, driving the telescopic rod 6 to move, so that the creasing wheel 8 moves on the cardboard for creasing treatment.

[0020] The limiting mechanism includes a limiting rod 4. The limiting rod 4 is fixedly connected to the first side plate 1. The limiting rod 4 penetrates through the moving block 5. The limiting rod 4 plays a role in limiting the moving block 5, preventing the limiting block 5 from rotating.

[0021] A connecting frame 7 is fixedly connected to the telescopic rod 6. A rotating shaft is rotatably connected to the connecting frame 7 through a bearing. A cross 17 is fixedly connected to the rotating shaft. A plurality of creasing wheels 8 are arranged on the cross 17. The widths of the plurality of creasing wheels 8 are all different. The rotating shaft is adjusted by an adjusting mechanism. By rotating the rotating shaft, different thickness creasing wheels 8 are switched to abut against the cardboard, so as to meet the creasing and folding requirements of cardboard with different thicknesses.

[0022] The adjusting mechanism includes a fixed ear 16. The fixed ear 16 is fixedly connected to the connecting frame 7. A second threaded rod 12 is threadedly penetrated through the fixed ear 16. A rack 15 is rotatably connected to the second threaded rod 12 through a bearing. A gear 14 is engaged with the rack 15. The gear 14 is fixedly connected to the rotating shaft. By rotating the second threaded rod 12, the rack 15 is driven to move, thereby driving the gear 14 to rotate, so that the gear 14 drives the rotating shaft to rotate and switches the creasing wheels 8.

[0023] When in use: Place the cardboard on the base 11. According to the thickness of the cardboard, rotate the second threaded rod 12, which will drive the rack 15 to move, thereby driving the gear 14 to rotate, so that the gear 14 drives the rotating shaft to rotate, switch the creasing wheels 8, and abut the corresponding creasing wheels 8 against the cardboard. The telescopic rod 6 extends for creasing treatment. Subsequently, the motor 2 rotates, driving the first threaded rod 3 to rotate, thereby adjusting the position of the moving block 5, driving the telescopic rod 6 to move, so that the creasing wheels 8 move on the cardboard.

[0024] Example 2: Refer to Figures 1-3 , As another preferred embodiment of the present utility model, on the basis of Embodiment 1, a second side plate 9 is fixedly connected to the base 11. An abutting plate 10 is arranged on the base 11. The abutting plate 10 is arranged parallel to the second side plate 9 to abut against both sides of the cardboard, preventing the cardboard from shifting during creasing.

[0025] Embodiment 3: In Embodiment 2, only cardboard of a fixed specification can be prevented from shifting. Refer to Figures 1-4 , as another preferred embodiment of the present utility model, on the basis of Embodiment 2, a connecting ear 20 is fixedly connected to the abutting plate 10, a bolt 19 is threadedly penetrated through the connecting ear 20, and a plurality of threaded holes 18 are equidistantly opened on the base 11.
