[0016] A die-cutting method for a cigarette packaging box cardboard die-cutting device, the die-cutting method comprising the following steps:

[0017] In the first step, after the processed cardboards are stacked on the placement frame in sequence, the stacked cardboards are sorted by the cardboard sorting structure so that the cardboards are neatly arranged and stacked in the placement frame;

[0018] In the second step, the die-cutting moving structure can drive the positions of the two cardboard die-cutting structures to move downward, and move the positions of the two cardboard die-cutting structures and the two electronic eyes to the top of the cardboard;

[0019] The third step is to identify the two color marks on the cardboard through two electronic eyes, and then transmit the position information of the color marks to the die-cutting adjustment structure;

[0020] The fourth step is that the die-cutting adjustment mechanism drives the positions of the two cardboard die-cutting mechanisms to be adjusted, and the positions of the two die-cutting knives are adjusted to the top of the color mark on the cardboard;

[0021] In the fifth step, after the adjustment is completed, the two cardboard die-cutting structures respectively drive the positions of the two die-cutting knives to move downward to perform die-cutting on the cardboard, and during the die-cutting process, the cardboard pressing structure moves downward through the die-cutting moving structure to press and fix the position of the cardboard to be die-cut;

[0022] Step 6. After die-cutting is completed, the die-cutting cardboard is moved outward by the cardboard moving structure so as to subsequently unload the cardboard and waste.

[0023] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0024] Firstly, after the position of the color mark on the cardboard is identified by the electronic eye, the present invention transmits the corresponding signal to the controller. At this time, the controller will control the adjustment motor to work. The adjustment motor drives the adjustment gear to rotate, which can drive the two adjustment tooth plates to move away from or close to each other at the bottom of the moving frame, thereby driving the positions of the two adjustment plates to move, and the position of the die-cutting knife on the adjustment plate is adjusted. While adjusting, the position of the electronic eye is also driven to move, and the position of the electronic eye is moved to the position of the color mark on the cardboard. When the electronic eye senses the position of the color mark, it will transmit the signal to the controller, and the controller controls the adjustment motor to stop working. In the process of die-cutting the cardboard, the position of the two adjustment plates can be controlled according to the position of the color mark on the cardboard, so that the position of the two die-cutting knives can be driven to move horizontally, and the position of the die-cutting knife can be accurately moved to the color mark of the cardboard, so that the cardboard can be die-cut later and the excess waste outside the color mark on the cardboard can be cut off.

[0025] Secondly, when die-cutting cardboard, the present invention needs to press and fix the cardboard at the position of the die-cutting knife. At this time, the movable cylinder drives the position of the movable frame to move downward, thereby driving the position of the pressing plate to be located above the cardboard. The adjustment motor drives the position of the two adjustment plates to move. When the positions of the two die-cutting knives are adjusted, the positions of the two extension plates can also be driven to slide on the two pressing plates, thereby moving the position of the extension plates to the side of the cardboard die-cutting knife. Finally, when the movable cylinder drives the pressing plate downward to press the cardboard, the extension plate can be driven to move up and down on the adjustment plate through two sliding rods to press and fix the paper to be die-cut, thereby preventing the cardboard die-cutting position from warping or curling during the die-cutting process, thereby affecting the accuracy of the cardboard die-cutting.

[0026] Thirdly, in the process of die-cutting the cardboard, the die-cutting oil cylinder drives the die-cutting frame to move downward on the adjustment plate, which can drive the position of the die-cutting knife to move downward, and perform die-cutting on the stacked cardboard. The die-cutting position is located at the color mark position on the cardboard, so as to perform die-cutting on the cardboard more accurately.

[0027] After die-cutting, the placement frame is in the interval of loading, and the die-cutting cylinder drives the die-cutting frame up and down, thereby driving the position of the die-cutting knife to move up and down reciprocatingly. At this time, the position of the die-cutting knife moves up and down, and the die-cutting knife can also dissipate heat to prevent the high temperature of the die-cutting knife from melting the glue on the cardboard during the next die-cutting process, causing the cardboard to stick.
