[0002] Paper packaging boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. They need to be prepared by die-cutting, creasing, nailing or gluing. Packaging box production requires creasing the cardboard to facilitate packaging.

[0003] In existing technologies, cardboard needs to be manually placed into the creasing machine's feeding area before the machine creasing it. This semi-automated production method not only consumes a lot of labor but also makes the entire process unsustainable. Workers need to repeatedly perform heavy and monotonous feeding operations, which has become a bottleneck restricting the improvement of packaging box production efficiency. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 The creasing device shown includes a worktable 1 and a pusher plate 10, as shown. Figure 1 As shown, the workbench 1 has two side plates 26 connected parallel to its length. A conveyor belt 14 is mounted on both side plates 26. The continuous operation of the conveyor belt 14 automates the feeding of the cardboard, thus connecting the feeding and creasing processes. The side plates 26 are equipped with adjustment structures 4 for adjusting the position of the raw materials. The workbench 1 is connected to a support frame 3, which has an adjustment groove 16. Two sliders 17 are slidably connected to the inner wall of the adjustment groove 16. Figure 2 As shown, a connecting rod 20 is rotatably connected to the bottom of slider 17, and a creasing wheel 21 is rotatably connected to the bottom of connecting rod 20. The creasing wheel 21 can press creases into the cardboard. Slider 17 and connecting rod 20 are connected to a depth adjustment structure, which allows precise control of the pressing depth of the creasing wheel 21 to accommodate cardboard of different thicknesses. Slider 17 is connected to a spacing adjustment structure, which can drive the two sliders 17 to move synchronously in opposite directions or in opposite directions, thereby adjusting the distance between the two creasing wheels 21 to match the creasing requirements of different sized cardboard.

[0025] like Figure 1As shown, a storage bin 2 is connected to the left side of the workbench 1. The storage bin 2 has a chute 12 and a discharge port 13. The height of the discharge port 13 is between the thickness of one to two sheets of raw material. The push plate 10 is slidably connected to the inner wall of the chute 12, and its function is to push the stacked cardboard out of the discharge port 13. Two identical connecting plates 8 are connected to the left side of the push plate 10. The connecting plates 8 have drive grooves 11. The workbench 1 is connected to a first motor 5. The output end of the first motor 5 is connected to a turntable 6. The turntable 6 is connected to a drive rod 7. The drive rod 7 is slidably connected to the inner wall of the two drive grooves 11. The first motor 5 drives the turntable 6 to rotate. Through the sliding of the drive rod 7 in the drive groove 11, the circular motion is converted into the linear reciprocating motion of the push plate 10, realizing automatic and continuous feeding.

[0026] like Figure 1 As shown, the adjustable spacing structure includes a second motor 15 connected to the support frame 3. The output end of the second motor 15 is connected to a bidirectional screw 18. Two sliders 17 are threadedly connected to the bidirectional screw 18 respectively. The second motor 15 drives the bidirectional screw 18 to rotate. By using the threads on the screw that are in opposite directions, the two sliders 17 are driven to move synchronously in opposite directions, thereby realizing the electric adjustment of the indentation spacing.

[0027] like Figure 2 As shown, the depth adjustment structure includes a second adjustment block 23 rotatably connected to the slider 17, an adjustment screw 24 rotatably connected to the second adjustment block 23, a first adjustment block 22 rotatably connected to the connecting rod 20, the first adjustment block 22 being threadedly connected to the adjustment screw 24, and a first knob 25 connected to the adjustment screw 24. By manually rotating the first knob 25, the adjustment screw 24 is rotated, driving the first adjustment block 22 to move along the screw, thereby changing the tilt angle of the connecting rod 20, and finally achieving fine adjustment of the height of the indentation wheel 21 to set a suitable indentation depth.

[0028] like Figure 1 As shown, the inner wall of the adjustment groove 16 is provided with a guide groove 32, such as... Figure 2 As shown, the slider 17 is connected to the locking block 19, which is slidably connected to the inner wall of the guide groove 32. Its function is to ensure that the slider 17 slides smoothly along a straight line under the drive of the bidirectional screw 18, prevent it from deflecting, and improve the stability and accuracy of the adjustment process.

[0029] like Figure 3As shown, the adjustment structure 4 includes a worm gear 29, and an adjustment groove 27 is provided on the side plate 26. An adjustment plate 28 and a worm 30 are rotatably connected to the inner wall of the adjustment groove 27. The adjustment plate 28 is connected to the worm gear 29, and the worm gear 29 meshes with the worm 30. A second knob 31 is connected to the top of the worm 30. By rotating the second knob 31, the worm 30 is driven to rotate, which in turn drives the meshing worm gear 29 and the adjustment plate 28 to rotate, thereby changing the relative position between the two side plates 26 to adjust the effective working width of the conveyor belt 14 and realize the adjustment of the position of the raw materials. The worm gear mechanism has a self-locking characteristic, which can ensure that the adjusted position remains fixed.

[0030] like Figure 1 As shown, the workbench 1 is rotatably connected to a stabilizing turntable 9, and the drive rod 7 is connected to the stabilizing turntable 9. The turntable 6 and the stabilizing turntable 9 are the same size, and their function is to jointly support the drive rod 7, ensuring its balance and stability during rotation, preventing vibration or jamming caused by unilateral force, and making the feeding and pushing action more smooth and reliable.

[0031] The specific implementation process is as follows:

[0032] First, according to the specifications of the cardboard to be processed, rotate the second knob 31 to drive the worm gear 29 through the worm 30, causing the adjusting plate 28 to rotate in the adjusting groove 27, adjusting the distance between the two side plates 26 to set the appropriate width of the conveyor belt 14; then start the second motor 15 to drive the bidirectional screw 18 to rotate, causing the two sliders 17 to move towards or away from each other along the guide groove 32, driving the indentation wheel 21 to adjust to the required indentation distance; then rotate the first knob 25 to drive the adjusting screw 24 to rotate, through the cooperation of the first adjusting block 22 and the second adjusting block 23 Rotate the connecting rod 20 relative to the slider 17 to adjust the creasing wheel 21 to the predetermined creasing depth. After completing the equipment parameter settings, place the stacked cardboard into the storage box 2, start the first motor 5 to drive the turntable 6 and the stabilizing turntable 9 to rotate synchronously, and drive the drive rod 7 to slide in the drive groove 11 of the connecting plate 8, pushing the push plate 10 to reciprocate along the slide groove 12, pushing the cardboard from the discharge port 13 one by one to the conveyor belt 14. When the cardboard is conveyed to the creasing wheel 21 by the conveyor belt 14, it completes the creasing process by passing through the creasing wheel 21 under the drive of the conveyor belt 14.
