[0039] As Figures 1 - 3 shown, in this embodiment, the cigarette machine die cooling system is used to cool the steel die roller 100. The cigarette machine die cooling system includes two brackets 1 and a fixing component. Among them, the two brackets 1 are respectively arranged on both sides of the steel die roller 100. The bracket 1 has a first fixing hole 2, a second fixing hole 3 and a connecting hole 4. The connecting hole 4 is configured to be rotationally connected to the steel die roller 100. An air guide groove 41 is formed on the inner wall of the connecting hole 4. The bracket 1 is provided with a first air path 11 and a second air path 12. The two ends of the first air path 11 are respectively communicated with the first fixing hole 2 and the air guide groove 41. The two ends of the second air path 12 are respectively communicated with the second fixing hole 3 and the air guide groove 41. The fixing component includes a first fixing shaft 5 and a second fixing shaft 6. The two ends of the first fixing shaft 5 are respectively inserted into the first fixing holes 2 of the two brackets 1. The first fixing shaft 5 is provided with an air inlet 51. The air inlet 51 is communicated with the first air path 11, and the air inlet 51 is connected to an external air source. The two ends of the second fixing shaft 6 are respectively inserted into the second fixing holes 3 of the two brackets 1. The second fixing shaft 6 is provided with a gas channel 61. The two ends of the gas channel 61 are respectively communicated with the air guide groove 41 and the second air path 12. Specifically, a steel die roller 100 for printing marks on cigarette paper is rotatably arranged between the two brackets 1, and the two brackets 1 are connected and fixed by the first fixing shaft 5 and the second fixing shaft 6. An air inlet 51 is formed at the end of the first fixing shaft 5. A gas channel 61 is formed along the center line of the second fixing shaft 6. The air inlet 51 of the first fixing shaft 5 is connected to an external air source. There are two requirements for the selection of the air source: one is that it does not affect the normal production of the equipment, and the other is that the air path is connected during normal production and the air path is closed during shutdown, which is convenient for maintenance. The working principle of the cigarette machine die cooling system is as follows: Start the external air source. The gas enters the inlet of the first air path 11 through the air inlet 51 of the first fixing shaft 5. The gas in the first air path 11 reaches the air guide groove 41 from the outlet of the first air path 11. Under the action of the air guide groove 41, a part of the gas cools one end of the steel die roller 100 by air cooling. Another part of the gas in the air guide groove 41 enters the inlet of the second air path 12 of another bracket 1 through the gas channel 61 of the second fixing shaft 6. The gas in the second air path 12 reaches the guide groove of the bracket 1 from the outlet of the second air path 12, and cools the other end of the steel die roller 100 by air cooling under the action of the guide groove. The cigarette machine die cooling system can play a role in cooling the steel die roller 100, with good cooling effect, and avoid the ink on the steel die roller 100 from drying and sticking due to the long-term operation and heating of the die system.

[0040] Further, continue to refer to Figures 1 - 3, along the axial direction of the embossing roller 100, the air guide groove 41 extends, and one end of the air guide groove 41 opens towards the embossing roller 100. Specifically, there are multiple air guide grooves 41. Along the circumferential direction of the connection hole 4, the multiple air guide grooves 41 are arranged at intervals, and the multiple air guide grooves 41 are communicated through a common channel. That is, the gas entering the first air path 11 from the air inlet 51 of the first fixed shaft 5 enters the air guide groove 41 from the outlet of the first air path 11, and is distributed into the multiple air guide grooves 41 under the action of the common channel. The gas in the multiple air guide grooves 41 cools the embossing roller 100 at the same time, improving the cooling effect on the embossing roller 100.

[0041] Further, continue to refer to Figures 1 - 3 , the second fixed shaft 6 has a hollow structure. Specifically, the second air path 12 of the second fixed shaft 6 extends along its axial direction, and the air inlet 51 and the air outlet of the second air path 12 are the two ends of the second fixed shaft 6. Under the action of the second air path 12 of the second fixed shaft 6 with a hollow structure, the two brackets 1 perform air path transmission.

[0042] Further, continue to refer to Figures 1 - 3 , there are two second fixing holes 3 and two embossing rollers 100. The two second fixing holes 3 are respectively located below the corresponding embossing rollers 100. There are two second fixed shafts 6. The two second fixed shafts 6 are parallel to each other and are respectively arranged in the corresponding second fixing holes 3. Specifically, there are two connection holes 4. The gas from the external air source enters from the air inlet 51 of the first fixed shaft 5, and then is divided into two paths and enters the left and right first air paths 11 of the same bracket 1 respectively, and reaches the air guide grooves 41 of the corresponding connection holes 4 through the two first air paths 11. The air guide grooves 41 of the two connection holes 4 respectively cool the two embossing rollers 100 by air cooling.

[0043] Further, continue to refer to Figures 1 - 3 , the fixing assembly further includes a first locking nut 7. The first locking nut 7 is sleeved on the shaft end of the first fixed shaft 5 and can abut against the bracket 1. The first fixed shaft 5 is detachably connected to the bracket 1, which is convenient for replacing and repairing the first fixed shaft 5.

[0044] Further, continue to refer to Figures 1 - 3 , the fixing assembly further includes a second locking nut 8. The second locking nut 8 is sleeved on the shaft end of the second fixed shaft 6 and can abut against the bracket 1. The second fixed shaft 6 is detachably connected to the bracket 1, which is convenient for replacing and repairing the second fixed shaft 6.

[0045] This embodiment also provides a cigarette making unit, which includes a frame and a die cooling system of the cigarette making machine. The die cooling system of the cigarette making machine is arranged on the frame. Specifically, when an external air source is started, the gas enters the inlet of the first air path 11 through the air inlet 51 of the first fixed shaft 5. The gas in the first air path 11 reaches the air guide groove 41 from the outlet of the first air path 11. Under the action of the air guide groove 41, part of the gas cools one end of the steel printing roller 100 by air cooling. Another part of the gas in the air guide groove 41 enters the inlet of the second air path 12 of another bracket 1 through the gas passage 61 of the second fixed shaft 6. The gas in the second air path 12 reaches the guide groove of the bracket 1 from the outlet of the second air path 12, and cools the other end of the steel printing roller 100 by air cooling under the action of the guide groove. This die cooling system of the cigarette making machine can play a role in cooling the steel printing roller 100, making the cooling effect of the cigarette making unit good.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention.
