[0026] This application provides a creasing device for cardboard box processing, as shown in the schematic diagram below. Figure 1-5 As shown. A creasing device for carton processing; including a processing table 10, with fixed plates 20 on both sides of one end of the processing table 10, and two threaded rods 30 rotatably connected between the two fixed plates 20, with the two threaded rods 30 located at the same vertical section position.

[0027] Each threaded rod 30 is equipped with four adjusting nuts 50, and an indentation wheel 40 is installed between every two adjusting nuts 50. A transmission mechanism 60 is installed on one side of the fixing plate 20 to make the two threaded rods 30 rotate synchronously and in opposite directions.

[0028] It should also be noted that all electrical components in this device are externally powered and electrically connected to a conventional PLC controller.

[0029] For details, please refer to the appendix. Figure 1 Two conveyor rollers 70 are also installed between the two fixed plates 20, and the two conveyor rollers 70 are located at the same vertical section position.

[0030] It should be noted that in this embodiment, the operation of the two conveyor rollers 70 enables the cardboard to be stably displaced toward the rear end, thereby achieving stable indentation.

[0031] For details, please refer to the appendix. Figure 2 One of the fixed plates 20 is a hollow structure. The transmission mechanism 60 includes four connecting shafts 62 that are respectively connected to one end of the two conveying rollers 70 and one end of the two threaded rods 30 and pass through the interior of the fixed plate 20; two sets of transmission pulleys 64 respectively sleeved on the connecting shafts 62 at the same height; two transmission gears 63 installed on the connecting shafts 62 connected to the two conveying rollers 70 and meshing with each other; and a first motor 61 connected to one of the connecting shafts 62.

[0032] It should be noted that in this embodiment, the transmission belt 64 can be a gear track type to ensure transmission performance.

[0033] Through the transmission of two sets of drive belts 64 and two drive gears 63, the two threaded rods 30 and two conveyor rollers 70 can be rotated synchronously. The top threaded rod 30 and the conveyor rollers 70 rotate in opposite directions to the bottom two, so that the cardboard can be conveyed and creasing can be performed at the same time.

[0034] For details, please refer to the appendix. Figure 3 The indentation roller 40 is composed of two semicircular first pressure rollers 41 and second pressure rollers 42.

[0035] It should be noted that, in this embodiment, the semi-circular first pressure roller 41 and second pressure roller 42 facilitate the removal of the indentation roller 40 from the threaded rod 30, thereby allowing the selection of an indentation roller 40 of appropriate thickness for installation.

[0036] For details, please refer to the appendix. Figure 3 The second pressure roller 42 has two insertion blocks 43 on its top sides. One side of the insertion block 43 has a receiving groove 44. A spring 45 and a latching block 46 are installed in the receiving groove 44. The bottom of the first pressure roller 41 has two slots that are compatible with the insertion blocks 43. One side of the slots has a latching groove 47 that is compatible with the latching block 46.

[0037] It should be noted that in this embodiment, when it is necessary to disassemble the indentation wheel 40, press the snap block 46 in the snap slot 47 to retract it, and then separate the first pressure wheel 41 and the second pressure wheel 42 so that the insert block 43 can be pulled out of the slot, thereby facilitating the disassembly of the indentation wheel 40.

[0038] When it is necessary to install the indentation wheel 40 on the threaded rod 30, the insert block 43 can be inserted into the slot, and then the snap block 46 will pop out in the snap slot 47 by the force of the spring 45 to complete the convenient installation of the indentation wheel 40.

[0039] For details, please refer to the appendix. Figure 4 The adjusting nut 50 is composed of a torsion ring 51 with a smaller outer diameter and a retaining ring 52 with a larger outer diameter. Multiple triangular baffles 53 are provided on the side of the torsion ring 51.

[0040] It should be noted that, in this embodiment, the triangular baffle 53 allows the operator to easily rotate the adjusting nut 50, thereby facilitating the adjustment of the position of the adjusting nut 50.

[0041] For details, please refer to the appendix. Figure 5 The processing table 10 is provided with a slide groove, and a limiting mechanism 80 is provided in the slide groove. The limiting mechanism 80 includes a positive and negative lead screw 81 rotatably connected in the slide groove, a second motor 82 connected to the positive and negative lead screw 81, and a limiting plate 83 symmetrically slidably connected to the positive and negative lead screw 81 at its bottom.

[0042] It should be noted that in this embodiment, the operation of the second motor 82 can cause the positive and negative lead screws 81 to rotate, and the limiting plates 83 symmetrically located at both ends of the positive and negative lead screws 81 will move closer or further away in sync, adjusting the distance between the two limiting plates 83, thereby adjusting according to the width of the paperboard being processed, ensuring that the paperboard is within this range during conveying, and ensuring the accuracy of the indentation position.

[0043] The specific operation method of this utility model is as follows:

[0044] First, adjust the distance between the two limiting plates 83 according to the width of the cardboard to be processed. By operating the second motor 82, the positive and negative lead screws 81 can be rotated, and the limiting plates 83 symmetrically located at both ends of the positive and negative lead screws 81 will move closer or further away in sync, thereby completing the adjustment so that the distance between the two limiting plates 83 is adapted to the width of the cardboard to be processed.

[0045] Then adjust the position of the crease according to the required crease width and crease position of the cardboard being processed. Turn the adjusting nut 50 to adjust its position, then install the crease wheel 40 of appropriate thickness, and then fix the crease wheel 40 between the two adjusting nuts 50.

[0046] Then, the transmission mechanism 60 is started, and the paperboard is conveyed through the conveyor roller 70. When the paperboard passes between the two threaded rods 30, the rotating creasing wheel 40 completes the creasing process on the paperboard.

[0047] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
