[0021] When this embodiment is used, the cardboard is conveyed to the die-cutting machine 1 by the conveying component a2, the hydraulic cylinder 10 moves the printing roller 15 to a suitable processing position in advance according to the thickness of the cardboard, the motor 12 drives the pulley a13 to rotate, the pulley a13 drives the pulley b16 to rotate through the transmission belt 14, and the pulley b16 drives the printing roller 15 to rotate, so that the machine can process cardboards of different thicknesses, thereby improving the versatility of the machine, and multiple conveying rollers 17 convey the cardboard to the printing roller 15, the die-cutting knife 18 and the conveying component a2 in sequence. After the die-cutting knife 18 cuts the cardboard, the limit roller 19 provided on the die-cutting machine 1 is also rotated to sweep down the cardboard debris falling on the cardboard, thereby avoiding the cardboard debris affecting the subsequent cardboard processing and improving the processing quality of the machine.

[0022] Embodiment 2

[0023] like Figure 1 and Figure 2As shown, a four-color printing slotting die-cutting machine proposed in this embodiment, compared with the first embodiment, in this embodiment, a water tank 3, a ventilation pipe 9 and a plurality of fans 26 are provided on the die-cutting machine 1, the ventilation pipe 9 is respectively connected with the installation places of the plurality of fans 26 and the water tank 3, a filter plate 4 is detachably provided on the top of the water tank 3, a water inlet pipe part 7 is provided on the water tank 3, and a control valve 8 is provided on the water inlet pipe part 7, so as to ensure sufficient water flow inside the water tank 3, the die-cutting machine 1 has an input channel and an output channel for entering and exiting paperboard, and the plurality of fans 26 are respectively located at the top of the input channel and the top of the output channel.

[0024] The cleaning assembly includes a water pump 5 arranged at the top of the die-cutting machine 1, a cleaning frame 24 and a water spray frame 25 arranged relatively on the die-cutting machine 1, and a water outlet pipe 6 connected to the water tank 3, the water pump 5 and the water spray frame 25 in sequence. The bottom of the cleaning frame 24 and the water spray frame 25 are both provided with baffles, which are used to prevent water from spraying onto cardboard debris and causing the cardboard to stick to the machine, thereby reducing the maintenance frequency of the machine. A closed door 23 is provided on the die-cutting machine 1 to rotate and seal, and the closed door 23 is located at the cleaning assembly. The lifting frame 11, the cleaning frame 24 and the water spray frame 25 are not connected to the side of the die-cutting machine 1.

[0025] In this embodiment, when the cardboard is being printed and die-cut, multiple fans 26 blow the air at its bottom toward the ventilation pipe 9, the air density at the bottom of the fan 26 is reduced, and the air inside the die-cutting machine 1 is brought into the ventilation pipe 9. The pigment used for printing carries a certain amount of substances harmful to the human body, and the harmful substances will be emitted into the air. Multiple fans 26 send harmful gases into the water tank 3, so that the water performs a preliminary filtration on the harmful gases, and then the filtered gases are secondary filtered through the filter plate 4 arranged on the top of the water tank 3, thereby ensuring the health of the workers. After the cardboard die-cutting is completed, the printing roller 15 is brought to the cleaning component by the lifting frame 11, and the motor 12 drives the printing roller 15 to rotate. The printing roller 15 is in rotational contact with the cleaning frame 24 and the water spray frame 25, thereby fully cleaning the surface of the printing roller 15, thereby ensuring the production quality of the machine. When the machine needs to be maintained, the worker opens the closed door 23 to maintain and replace the inside of the machine, thereby reducing the difficulty of machine maintenance.

[0026] Embodiment 3

[0028] In this embodiment, when the cleaning component cleans the printing roller 15, the waste water generated by the cleaning will flow into the waste liquid tank 22 along the telescopic hose 21. When the waste liquid tank 22 is almost full, the worker can pull the waste liquid tank 22 out from the bottom of the die-cutting machine 1 for cleaning by moving the component, thereby reducing the difficulty of cleaning the waste liquid. When die-cutting cardboard, the die-cut cardboard scraps will fall onto the conveying component b20, and the conveying component b20 will send the cardboard scraps out of the die-cutting machine 1 for recycling, thereby avoiding the accumulation of cardboard scraps affecting the normal operation of the machine.

[0029] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
