[0002] Packaging boxes are used to package products, protecting them from damage caused by impacts, vibrations, and other mechanical loads during distribution. Packaging boxes can be categorized by material, such as cardboard boxes, tin boxes, and wooden boxes. Cardboard boxes are a type of packaging box, named for their high-strength cardboard material. Common materials for cardboard boxes include corrugated cardboard, white cardboard, and kraft paper. Cardboard boxes are widely used due to their lightweight, portability, and low cost.

The lower part of the connecting plate 17 is connected to the pressure plate 18, and the first extension plate 221 and the second extension plate 24 are both slidably connected to the pressure plate 18.
[0027] like Figure 2 and Figure 3 As shown, the lateral adjustment mechanism includes a second screw 7, a second limiting block 8, a second servo motor 9, a first connecting block 10, and a third limiting block 11. The upper side of the fixing frame 1 is symmetrically and rotatably connected to the second screw 7. The second screw 7 is threadedly connected to the second limiting block 8.

The first connecting block 10 is snapped with the third limiting block 11.
[0028] like Figure 1 and Figure 5 As shown, it also includes a first baffle 31 and a second baffle 29. The first baffle 31 is connected to each of the limiting plates 3.

[0029] like Figure 1 and Figure 2 As shown, it also includes cylinder 12, second connecting block 13 and scale 14. Cylinder 12 is bolted to each of the second limiting blocks 8. The extension and retraction ends of cylinder 12 are connected to the second connecting blocks 13. The second connecting blocks 13 are rotatably connected to the third limiting block 11. There are four scales 14. Scales 14 are connected to the sides of the limiting plates 3 that are far apart from each other. Scales 14 are also symmetrically connected to the fixing frame 1.
[0030] like Figure 6 and Figure 7 As shown, it also includes a mounting plate 19, a turntable 20, a first bevel gear set 21, and a third screw 22. Two mounting plates 19 and two turntables 20 are connected to the pressure plate 18. The turntables 20 are rotatably connected to each mounting plate 19.

[0031] like Figure 6 and Figure 7 As shown, it also includes a fourth screw 23 and a second bevel gear set 231. The lower end of the left turntable 20 is connected to the second bevel gear set 231. The left side of the pressure plate 18 is symmetrically and rotatably connected to the fourth screw 23. The ends of the fourth screw 23 that are close to each other are connected to the second bevel gear set 231. The second extension plate 24 is threadedly connected to the fourth screw 23.
[0032] When using this device, first place the packaging box paper that needs to be folded in the center position between the limiting blocks, and then drive the first electric slide rail 16. The first electric slide rail 16 will press down with the connecting plate 17, and the connecting plate 17 will press down with the pressing component. When the pressing component contacts the packaging box paper and continues to press down, the middle of the packaging box paper will be pressed down by the pressing component, and the perimeter of the packaging box paper will be clamped between the side of the pressing component and the limiting blocks. As the pressing component continues to press down, the perimeter of the packaging box paper will become vertical. When the pressing component presses down to the maximum value, the bottom surface of the packaging box paper contacts the pusher 28, forming a crease. At this time, the packaging box paper becomes a three-dimensional cardboard box. When folding packaging boxes of different specifications, the vertical length adjustment steps are as follows: First drive the first servo motor 6, the first servo motor 6 outputs... The output shaft will rotate together with the first screw 5. The two limiting plates 3 will slide together with the first limiting block 4, the second limiting block 8 and the third limiting block 11 on the first screw 5 to the front and back sides respectively, thereby increasing the distance between the limiting plates 3. After the limiting plates 3 are precisely adjusted to the preset vertical length by observing the scale 14, the first servo motor 6 is turned off to stop moving the limiting plates 3. Then the horizontal length is adjusted: the second servo motor 9 is driven, and the output shaft of the second servo motor 9 will move the second limiting block 8 and the third limiting block 11 to the right together, thereby increasing the distance between the first limiting block 4 and the second limiting block 8 and the third limiting block 11. After the second limiting block 8 and the third limiting block 11 are precisely adjusted to the preset horizontal length by observing the scale 14, the second servo motor 9 is turned off. This completes the adjustment of the limiting blocks.When the limiting plate 3 moves, the first baffle 31 also moves, thus disconnecting from the second extension plate 24. When the second limiting block 8 moves, the second baffle 29 also moves, thus disconnecting from the first extension plate 221. To accommodate the increased distance of the limiting block, the pressure plate 18 also needs to be adjusted accordingly: rotate the turntable 20 in sequence. The left turntable 20 will rotate with the second bevel gear set 231, and the second bevel gear set 231 will simultaneously rotate with the two fourth screws 23. When the fourth screws 23 rotate, the second extension plate 24 will move in opposite directions. When the second extension plate 24 re-contacts the first baffle 31, stop rotating the left turntable 20, thus realizing the vertical expansion and pressing assembly. The right turntable 20 will move with the first bevel gear set 221. When the bevel gear set 21 rotates, the first bevel gear set 21 will drive the third screw 22 to rotate. As the third screw 22 rotates, the first extension plate 221 will move to the right. When the first extension plate 221 re-engages with the second baffle 29, the rotation of the right-side turntable 20 stops, thus achieving lateral expansion of the pressing component. Due to the presence of the first baffle 31 and the second baffle 29, the pressing component can precisely expand to an area corresponding to the moving distance of the limiting blocks, resulting in more standard folded packaging box paper. Repeating the above folding steps allows for the production of packaging boxes of corresponding specifications. This allows the device to adjust the distance of the limiting blocks according to production needs, thereby meeting diverse production requirements and effectively improving the adaptability and utilization rate of the device.
[0033] After the packaging box paper is folded, the cylinder 12 is driven. The telescopic end of the cylinder 12 will move the second connecting block 13 downward. At this time, the third limiting block 11 will tilt upward as the second connecting block 13 moves downward, so that the third limiting block 11 will not block the packaging box from moving to the right. The second electric slide rail 25 is driven, and the second electric slide rail 25 will move the second fixing plate 26 to the right. When the second fixed plate 26 moves to the right, the third electric slide rail 27 will also move to the right. The third electric slide rail 27 will move the pusher 28 and the packaging box on the pusher 28 to the right. When the second fixed plate 26 moves to its maximum right position, the third electric slide rail 27 will be driven to lower the pusher 28 and disconnect it from the packaging box, thus completing the step of transporting the packaging box to the right. This facilitates the continuation of the subsequent folding work and effectively improves the working efficiency of the device. Then, the second electric slide rail 25 will be driven to reset the second fixed plate 26. After the second fixed plate 26 is reset, the third electric slide rail 27 will be driven to reset the pusher 28. The subsequent work can be repeated by repeating the above steps. After the work is completed, the device can be turned off.
