Description

Technical Field

[0001] This utility model relates to the field of packaging processing technology, and more specifically, to a paper box folding device. Background Technology

[0002] In the production process of packaging boxes, a packaging box bending mechanism is needed to fold the die-cut flat box pieces. For example, a packaging box bending mechanism disclosed in CN221249985U adjusts the bending components to create a curved surface on the extrusion belt. As the flat box piece is transported on the extrusion belt, it is squeezed by rollers located above it, causing its sides to gradually bend along the continuous curved surface of the extrusion belt. The rollers dynamically flatten the undone portion. Furthermore, when the front end of the flat box piece touches the folding component on the mechanism, it is grasped and rotated along the folding rotating component, then immediately flattened and fixed by the flattening component, thus completing the front end fixation. This bending mechanism can simultaneously complete the front end folding and side edge bending of the flat box piece, enabling rapid assembly line operation.

[0003] However, the above-mentioned device still has problems in actual use: the bending component relies on manual adjustment, and the machine needs to be stopped during adjustment, resulting in low efficiency and easy deviation. Utility Model Content

[0026] Please see Figures 1-3 As shown, the main body of this embodiment is a cardboard box folding device, including a base 1, a conveyor belt 2 on the top of the base 1, a compression belt 3 above the conveyor belt 2, and the two sides of the compression belt 3 connected to the base 1 through lifting components; bending components are provided on both sides of the conveyor belt 2, and a driving component is provided on the outside of the mounting sleeve of the compression belt 3, and the driving component is connected to one side of the bending component; it also includes a controller, and the conveyor belt 2, the compression belt 3 and the driving component are all electrically connected to the controller.

[0027] Furthermore, the bending assembly includes a first trapezoidal plate 4 fixedly connected to the top of the base 1. The inclined surface of the first trapezoidal plate 4 is connected to a multi-stage bending plate composed of multiple second trapezoidal plates 5 hinged end to end. The outer side of the second trapezoidal plate 5 at the outermost end of the multi-stage bending plate is connected to the driving assembly.

[0028] Furthermore, such as Figure 1 As shown, the drive assembly includes a first telescopic cylinder, the outer end of the first cylinder body 6 of the first telescopic cylinder is connected to the side of the extrusion belt 3 via a first universal joint 8; the outer end of the first piston 7 of the first telescopic cylinder is connected to the outer side of the second trapezoidal plate 5 at the outermost end of the multi-stage bending plate via a second universal joint 9.

[0029] Furthermore, the top surface of the first trapezoidal plate 4 is rotatably connected with multiple guide rollers 10.

[0030] Furthermore, angle sensors 11 electrically connected to the controller are provided between adjacent second trapezoidal plates 5 and between the second trapezoidal plate 5 and the first trapezoidal plate 4. The angle sensors 11 are RSC-2800 type angle sensors. Multiple angle sensors form a sensor array on the multi-stage bending plate, thereby effectively detecting the overall bending state of the multi-stage bending plate.

[0031] Furthermore, a plurality of guide balls 12 are rotatably connected to the surface of the second trapezoidal plate 5. The guide balls 12 reduce the friction between the flat box piece and the multi-stage bending plate, facilitating the folding of the flat box piece.

[0032] Furthermore, the extrusion belt 3 is equipped with a pressure sensor 13 electrically connected to the controller. The pressure sensor 13 is a Subaru SBT296 flat-plate pressure sensor. The lifting assembly includes a fixed plate 14 fixedly connected to the base 1. A sliding plate 15 is vertically slidably mounted on the fixed plate 14. One side of the sliding plate 15 is fixedly connected to the outer side of the extrusion belt 3. A second telescopic cylinder electrically connected to the controller is provided on the outer side of the sliding plate 15. The second cylinder body 16 of the second telescopic cylinder is fixedly connected to the base 1, and the second piston 17 of the second telescopic cylinder is fixedly connected to the sliding plate 15.

[0033] First, the included angle between the second trapezoidal plates 5 is tested using angle sensors 11. Multiple angle sensors 11 form a sensor array on the multi-stage bending plate, thereby effectively detecting the overall bending state of the multi-stage bending plate. Then, the extension and retraction of the first piston 7 of the first telescopic cylinder is adjusted by the controller to adjust the bending state of the entire multi-stage bending plate to conform to the bending angle of the outer side of the planar box piece. The process is accurate and simple, and does not require machine shutdown for manual adjustment.

[0034] During the folding process, the flat box sheet is driven forward by the combined action of the conveyor belt 2 and the extrusion belt 3, and is kept straight by the action of the guide roller 10. When the two sides of the flat box sheet move to the multi-stage bending plate, the two sides of the flat box sheet are folded and bent along the bending state of the multi-stage bending plate under the action of the guide ball 12.

[0035] In addition, the pressure sensor 13 can detect the clamping force applied by the extrusion belt 3 to the flat box piece. If the clamping force is too high, the interior of the flat box piece will be over-compressed, resulting in structural damage. If the clamping force is too low, the two sides of the flat box piece will slip when folded and bent. Therefore, when the clamping force is too high or too low, the controller adjusts the extension and retraction of the second piston 17 of the second telescopic cylinder, thereby controlling the gap between the extrusion belt 3 and the conveyor belt 2 and controlling the clamping force.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
