[0001] The utility model belongs to the technical field of cigarette packaging equipment, in particular to a roller gas distribution plate of a cigarette packaging machine and a cigarette packaging machine. Background Art

[0002] Most of the raw and auxiliary materials of cigarette packaging machines are automatically conveyed and automatically spliced, and suction conveying is used to ensure conveying stability. For example, the YB47 packaging machine is equipped with two rollers and adsorption holes on the outer surfaces of the two rollers. The inner liner paper is adsorbed on different rollers to achieve the conveying of the inner liner paper.

[0003] However, in actual production, the suction force of the two rollers needs to be adjusted according to the actual situation. If the suction force of the roller surface is too small, the liner paper cannot be delivered properly and is easy to detach at the interface, resulting in liner paper blockage; if the suction force of the roller surface is too large, the liner paper is easy to "fly" when it is delivered, and the suction balance between the two rollers is difficult to adjust. The roller suction needs to be adjusted repeatedly to reduce it, which seriously affects the operating efficiency of the equipment. Utility Model Content

[0007] The gas distribution disk body is also provided with a positive pressure blowing hole, which is located at one side of the end of the negative pressure input cavity and is at a set distance from the end of the negative pressure storage cavity.

[0008] Furthermore, the negative pressure input chamber and the negative pressure storage chamber are respectively arranged on the outer surfaces of both sides of the gas distribution disk body.

[0009] Furthermore, a plurality of threaded holes are provided on the gas distribution disk body, and the gas distribution disk body is fixed to the gas distribution disk seat by bolts.

[0026] Embodiment 1

[0027] A typical implementation of the present utility model is as follows Figure 1 As shown, a roller gas distribution disk of a cigarette packaging machine includes a gas distribution disk body 1, which is made of oil-containing copper-based material. The gas distribution disk body 1 is semicircular, and the surface of the gas distribution disk body 1 is processed with a cavity and a through hole 2. The cavity includes a negative pressure input cavity 3 and a negative pressure storage cavity 4. The negative pressure input cavity 3 and the negative pressure storage cavity 4 are respectively arranged on two sides of the gas distribution disk body 1. The negative pressure input cavity 3 is connected to the negative pressure storage cavity 4 through the through hole 2. The bottom of the negative pressure input cavity 3 is connected to the negative pressure supply pipeline of the equipment to provide negative pressure.

[0028] The gas distribution disc body 1 is also provided with a plurality of threaded holes 6, and the gas distribution disc body 1 is fixed to the gas distribution disc seat by means of bolts, and thus the gas distribution disc seat is used to fix the gas distribution disc body 1 to one side of the roller of the cigarette packaging machine.

[0029] The negative pressure input chamber 3 is an arc-shaped sunken cavity, and a negative pressure input hole 7 is provided at one end of the negative pressure input chamber 3. The negative pressure input hole 7 is connected to the negative pressure supply pipeline of the equipment, and the negative pressure input chamber 3 is connected to the negative pressure storage chamber 4. The negative pressure enters the negative pressure storage chamber 4 through the negative pressure input chamber 3, ensuring that the negative pressure storage chamber 4 stores sufficient negative pressure.

[0030] The negative pressure storage cavity 4 is an arc-shaped concave cavity, which is arranged on one side of the gas distribution disk body 1. Negative pressure is input through the negative pressure input cavity 3 and stored in the cavity. When the gas distribution disk body 1 is fixed on one side of the roller of the cigarette packaging machine through the gas distribution disk seat, the negative pressure storage cavity 4 is arranged opposite to the roller of the cigarette packaging machine, so that the holes inside the roller of the cigarette packaging machine are used to provide negative pressure to the roller surface to adsorb the lining paper.

[0031] A positive-pressure blowing hole 8 is also provided on the air distribution disk body 1. The positive-pressure blowing hole 8 is provided at one end of the air distribution disk body 1, and is 8mm to 12mm away from the end of the negative-pressure storage cavity 4. A thread is provided on the inner wall of the positive-pressure blowing hole 8, and an M6 air pipe quick connector can be screwed into it for connecting the positive-pressure blowing air pipe for blowing. When the lining paper follows the roller to rotate to the position of the positive-pressure blowing hole 8, the suction hole of the roller here is converted from the original suction to positive-pressure blowing, and the lining paper at the corresponding position is no longer adsorbed.

[0032] Embodiment 2

[0033] The present embodiment provides a cigarette packaging machine, including a roller distribution plate of a cigarette packaging machine as described in the first embodiment, and also including a first roller 9 and a second roller 10, wherein the second roller 10 is arranged below the first roller 9, and a set distance is set between the first roller 9 and the second roller 10 to ensure that the lining paper can pass between the first roller 9 and the second roller 10, thereby realizing the transfer of the lining paper between the first roller 9 and the second roller 10.

[0034] The gas distribution disk body 1 is fixed to the side of the first roller 9 through the first roller gas distribution disk seat 11, and the negative pressure storage cavity 4 is arranged opposite to the first roller 9, so that the negative pressure storage cavity 4 is connected with the inside of the first roller 9, thereby evenly distributing the negative pressure to the inner lining paper adsorption area on the surface of the first roller 9.

[0035] A guide baffle 12 and a small plate 13 are also provided on the outside of the first roller 9, so the small plate 13 is fixed at one end of the guide baffle 12 and is located between the first roller 9 and the second roller 10. The liner paper adsorbed by the first roller 9 moves along the gap between the guide baffle 12 and the first roller 9, and the guide baffle 9 and the small plate 10 guide the movement of the liner paper.

[0036] When in use, the first gas distribution disc seat 11 is connected to the threaded hole of the gas distribution disc body 1 by screws, the main vacuum pipeline is opened for air supply, the gas distribution disc body 1 is pressed against the first roller 9, and the clamping ring 5 is locked. When the gas distribution disc body 1 is installed in place and the equipment is running, the negative pressure of the negative pressure supply device enters the negative pressure storage cavity 4 through the negative pressure input cavity 3 on the gas distribution disc body 1. The first roller 9 is connected to the negative pressure storage cavity 4 of the gas distribution disc, so that the small holes on the surface of the corresponding area of ​​the first roller 9 generate suction to absorb the inner lining paper. The inner lining paper rotates counterclockwise with the first roller 9. When it rotates to the position of the positive pressure blowing hole 8, the lining paper in the corresponding area of ​​the first roller 9 is no longer absorbed. The guide baffle 12 and the small plate 13 ensure that the inner lining paper will not curl. The inner lining paper continues to be conveyed, and is absorbed by the second roller 10 at the junction with the second roller 10, and rotates clockwise with the second roller 10 for subsequent conveying.
