Technical Field

[0001] This utility model relates to the field of cardboard box processing equipment technology, and in particular to an automatic cardboard box creasing machine. Background Technology

[0002] In the production and processing of cardboard boxes, creasing is an important process. Creases make it easier and neater to fold and shape the cardboard boxes, and can also improve the strength and appearance of the boxes.

In addition, the adjustment process of existing creasing machines is relatively complicated when creasing cartons of different specifications and sizes. Therefore, an automatic carton creasing machine is proposed to address the above problems. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-3 This utility model provides an embodiment of an automatic carton creasing machine, including a frame 1, adjustment mechanisms installed on both sides of the middle of the frame 1, lifting mechanisms set at the top of both ends of the frame 1, creasing mechanisms set between the lifting mechanisms, and an electrical control system installed on the left side of the front end of the frame 1. The frame 1 is equipped with a conveyor belt 11, which is prior art and will not be described in detail here. The lifting mechanism includes a fixed frame 21 fixed to the top of the side walls at both ends of the frame 1. A threaded rod 22 is installed inside the fixed frame 21. The top end of the threaded rod 22 is fixedly connected to the output end of the motor 23. The outer side of the threaded rod 22 is threadedly connected to the threaded hole inside the lifting block 24. A first displacement sensor 25 is installed on the outer side of the lifting block 24.

[0021] The indentation mechanism includes a lifting plate 31 disposed between the lifting blocks 24. Support plates 32 are provided on both sides of the limiting groove inside the lifting plate 31. A second threaded rod 35 is installed between the support plates 32. Multiple indentation components are installed on the outside of the second threaded rod 35.

[0022] The indentation assembly includes an internally threaded tube 333 sleeved on the outside of the second threaded rod 35. The internally threaded tube 333 is fixed inside the bearing sleeve 332. The bearing sleeve 332 is installed inside the translation block 331. The front and rear sides of the translation block 331 are in contact with the inner sidewall of the limiting groove of the lifting plate 31. The bottom of the translation block 331 is fixedly connected to the top of the connecting rod 334. The bottom of the connecting rod 334 is provided with an indentation wheel 335. The front end of the translation block 331 is provided with an alignment indicator rod 336. The bottom side of the alignment indicator rod 336 is in contact with the top side of the measuring scale 34. The measuring scale 34 is set on the surface of the lifting plate 31.

[0023] The adjustment mechanism includes hydraulic rods 41 set on both sides of the middle end of the frame 1. The extension end of the hydraulic rods 41 is equipped with an adjustment plate 42. The middle end of the adjustment plate 42 is equipped with a through-beam sensor 45. Multiple guide rollers 44 are provided inside the adjustment plate 42. A second displacement sensor 43 is installed on the top of the adjustment plate 42.

[0024] The through-beam sensor 45 is located behind the indentation roller 335. After the carton passes the detection position of the through-beam sensor 45, it reaches below the indentation roller 335.

[0025] The electrical control system includes a controller, a frequency converter, and a hydraulic rod controller. The frequency converter and the hydraulic rod controller are connected to the controller via control lines. The controller is connected to the through-beam sensor 45, the first displacement sensor 25, and the second displacement sensor 43 via data lines. The frequency converter is connected to the motor 23 via a circuit, and the hydraulic rod controller is connected to the hydraulic rod 41 via a circuit.

[0026] The cardboard board is placed on the conveyor belt 11 inside the frame 1, and moves forward with the conveyor belt 11. When the cardboard board moves to the adjustment mechanism on both sides of the middle of the frame 1, the through-beam sensor 45 detects the position of the cardboard board and transmits the signal to the controller. Based on the feedback information from the through-beam sensor 45, the controller controls the extension and retraction of the hydraulic rod 41 through the hydraulic rod controller, which drives the adjustment plate 42 to move. The guide roller 44 is used to fine-tune the position of the cardboard board to ensure that the cardboard board is in the appropriate indentation position. At the same time, the second displacement sensor 43 monitors the position of the adjustment plate 42 in real time and feeds it back to the controller.

[0027] Based on the required crease depth of the cardboard, the controller starts the motor 23, which drives the threaded rod 22 to rotate. The threaded rod 22 engages with the internal threaded hole of the lifting block 24, causing the lifting block 24 to move the lifting plate 31 up and down. The first displacement sensor 25 monitors the position of the lifting block 24 in real time and feeds it back to the controller, thereby precisely adjusting the height of the crease mechanism. Before use, based on the required crease position of the cardboard, the operator rotates the internal threaded tube 333, which moves on the second threaded rod 35, causing the translation block 331 to drive the crease wheel 335 to move laterally along the limiting groove of the lifting plate 31. The accurate position of the crease wheel 335 is determined by the alignment indicator rod 336 and the measuring scale 34.

[0028] After adjusting the height and position of the creasing mechanism, the carton board continues to move forward along the conveyor belt 11. When the carton board moves to below the creasing roller 335, the creasing roller 335 performs a creasing operation on the carton board, completing the creasing process of the carton board.
