[0002] Corrugated boxes are packaging containers made by laminating pre-formed core paper and linerboard to form corrugated cardboard, followed by printing, cutting, folding, and stapling. When folding corrugated cardboard, a folding device is needed. The folding rollers on the folding device press a crease into the surface of the corrugated paper, making it easier to fold the corrugated paper into a box.
[0003] Currently, most corrugated cardboard box production folding and pressing devices are placed on a workbench. The drive roller is turned on to move the cardboard onto the folding rollers, which press the cardboard into a crease. However, cardboard boxes need to be creased both horizontally and vertically. Traditional equipment can only crease in one direction. Therefore, after processing, the cardboard needs to be rotated and put back into the equipment for folding and pressing. This method is cumbersome and affects the processing efficiency of the cardboard. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figure 1 - Figure 7As shown, in this embodiment, a folding and pressing device for corrugated cardboard box production includes: a workbench 1; a drive mechanism 5, disposed on the workbench 1; a transverse folding and pressing mechanism 2, disposed on the workbench 1, wherein the drive mechanism 5 and the transverse folding and pressing mechanism 2 are configured to cooperate to fold and press the cardboard transversely; a support frame 4, disposed on the workbench 1; a drive device 10, mounted on the support frame 4; a reciprocating screw 9, rotatably connected within the support frame 4, and one end of the reciprocating screw 9 being drively connected to the output end of the drive device 10; and a sliding... The sliding frame 13 is slidably disposed within the support frame 4, and the reciprocating screw 9 is threadedly connected to the threaded hole within the sliding frame 13; the longitudinal folding mechanism 3 is disposed on the sliding frame 13; the drive rack 14 is fixedly connected to the support frame 4 and is disposed along the sliding direction of the sliding frame 13; the driven gear 15 is fixedly connected to one end of the rotating shaft of the longitudinal folding mechanism 3 and meshes with the drive rack 14; the sliding frame 13 is configured to longitudinally fold the cardboard when it moves with the reciprocating screw 9.
[0025] Through the structural design of the transverse folding mechanism 2 and the longitudinal folding mechanism 3, the corrugated cardboard is placed on the workbench 1. The drive mechanism 1 5 is turned on, and the drive mechanism 1 5 pushes the cardboard to move on the workbench 1. At the same time as it moves, the transverse folding mechanism 2 also rotates to fold the cardboard laterally. After the drive mechanism 2 6 pushes the cardboard under the support frame 4, the drive mechanism 2 6 is turned off, and the drive device 10 is turned on. The sliding frame 13 slides in the support frame 4. The driven gear 15 meshes with the drive rack 14, causing the longitudinal folding mechanism 3 to rotate and fold the cardboard longitudinally. This reduces the number of operation steps for workers and improves the folding efficiency of the equipment.
[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the transverse folding mechanism 2 includes a rotating rod 16, which is rotatably connected to the workbench 1 via a bracket; two folding rollers 17 are both mounted on the rotating rod 16. By rotating the folding rollers 17, the surface of the cardboard that has moved to the folding rollers 17 is folded and indented; the folding structure of the transverse folding mechanism 2 and the longitudinal folding mechanism 3 is the same.
[0027] like Figure 6 As shown, it also includes: several fixing holes 18, all of which are opened on the rotating rod 16; two screws 19, which are threaded into the threaded holes of the two pressure rollers 17 respectively; when the screws 19 and fixing holes 18 are set to cooperate, the position of the pressure rollers 17 on the rotating rod 16 is adjusted.
[0028] By turning screw 19, screw 19 moves along the threaded hole in the folding roller 17, moving one end of screw 19 out of the fixing hole 18, releasing the restriction of the folding roller 17 on the rotating rod 16, moving the folding roller 17, adjusting the position of the folding roller 17 on the rotating rod 16, and then turning screw 19 in the opposite direction to thread screw 19 into another fixing hole 18, thereby realizing the adjustment of the crease position of the folding roller 17 on the cardboard. This structural design can produce different models of cartons, improving the versatility of the equipment.
[0029] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes: a transmission belt 11, which is set above the workbench 1. The input end of the transmission belt 11 is fixedly connected to one end of the drive mechanism 5, and the output end of the transmission belt 11 is fixedly connected to one end of the rotating rod 16. When the drive mechanism 5 is turned on, the power transmission of the drive mechanism 5 is transmitted to the transmission rod of the transverse folding mechanism 2 through the transmission belt 11, which drives the folding roller 17 on the transverse folding mechanism 2 to rotate and fold the cardboard to create indentations.

When the pressure plate 21 is set to press down, it restricts the position of the cardboard on the workbench 1. By opening the cylinder 20, the cylinder 20 drives the pressure plate 21 to press down, and the pressure plate 21 fixes the cardboard. When the second drive mechanism 6 pushes the cardboard under the support frame 4, the other side of the cardboard presses on the drive rod of the second drive mechanism 6, thereby fixing the cardboard and preventing the cardboard from moving during folding and affecting the folding effect.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes: drive mechanism 1 5 including a motor and a drive roller, the output end of the motor is connected to one end of the drive roller for transmission, when the motor is turned on, the motor drives the drive roller to rotate, pushing the cardboard to move, wherein drive mechanism 1 5 and drive mechanism 2 6 have the same structure.
[0032] like Figure 1 and Figure 2As shown, it also includes: two guide frames 7, both set on the worktable 1, and the two guide frames 7 are symmetrical to each other; several guide rollers 8, respectively installed in the two guide frames 7; the two guide frames 7 form a material guiding channel on the worktable 1, and through the two guide frames 7, it is ensured that when the cardboard is placed on the worktable 1, it is in the middle position, preventing the creases of the cardboard from being misaligned, which would result in the produced cardboard being unqualified. The guide frames 7 are connected to the worktable 1 by bolts or fasteners.
[0033] This utility model provides a folding and pressing device for corrugated cardboard box production, the specific working principle of which is as follows:
[0034] When corrugated cardboard is placed in the folding device to create creases, the cardboard is first placed on the worktable 1. Drive mechanism 5 is activated, moving the cardboard on the worktable 1. Simultaneously, the transverse folding mechanism 2 rotates, folding the cardboard laterally. Drive mechanism 6 pushes the cardboard below the support frame 4, then deactivates it. Cylinder 20 is activated, causing pressure plate 21 to press down, fixing one side of the cardboard. When drive mechanism 26 pushes the cardboard below the support frame 4, the other side of the cardboard is pressed... The cardboard is fixed on the drive roller of the drive mechanism 26. Then the drive device 10 is turned on, the sliding frame 13 slides in the support frame 4, the driven gear 15 meshes with the drive rack 14, causing the longitudinal folding mechanism 3 to rotate and fold the cardboard longitudinally. After the cardboard is folded, the cylinder 20 is turned on, the pressure plate 21 releases the cardboard from the restriction, and a cardboard to be processed is placed on the worktable 1. When another cardboard needs to be moved under the support frame 4, the processed cardboard is pushed out from the feed port 22 by the cardboard to be processed, thus completing the processing.
