It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0035] The following description of at least one exemplary embodiment is actually merely illustrative and in no way limits the present invention or its application or use.

[0036] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the description.

[0037] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0038] As Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a conveying roller assembly of a cigarette making machine. The conveying roller assembly includes a conveying roller 1, a mounting shaft 2, and a plurality of connecting members 3.

[0039] The conveying roller 1 has a body 11, a mounting portion 12, and a notch portion 13. The mounting portion 12 is provided at the center of the body 11, and the notch portion 13 extends from the mounting portion 12 towards the outer periphery of the body 11.

[0040] A plurality of connecting members 3 are arranged on the mounting shaft 2 at intervals. The inner side wall of the connecting member 3 is adapted to the outer peripheral wall of the mounting shaft 2, and the outer wall of the connecting member 3 is connected to the body 11.

[0041] In the present invention, by providing a mounting portion 12 at the center of the body 11 of the conveying roller 1 and a notch portion 13 extending from the mounting portion 12 towards the outer periphery of the body 11, and arranging a plurality of connecting members 3 on the mounting shaft 2 at intervals, and making the inner side wall of the connecting member 3 adapted to the outer peripheral wall of the mounting shaft 2 and the outer wall of the connecting member 3 connected to the body 11, the conveying roller 1 is fixed on the mounting shaft 2, which increases the convenience of installation and disassembly of the conveying roller 1, reduces the steps and time in the process of maintenance and replacement of the conveying roller 1, reduces the difficulty of installation and disassembly of the conveying roller 1, and meets the needs of users.

[0042] In an embodiment of the conveying roller assembly of the cigarette making machine of the present invention, the notch portion 13 is formed by combining a semi-circular notch and a sector-shaped notch. By setting the notch portion 13 as a combination of a semi-circular notch and a sector-shaped notch, while ensuring the convenience of installing the conveying roller 1 on the mounting shaft 2, it also ensures the contact area between the outer peripheral wall of the body 11 of the conveying roller 1 and the transparent paper, so that more of the outer peripheral wall of the body 11 of the conveying roller 1 is in contact with the transparent paper, thereby ensuring the conveying frequency of the transparent paper.

[0043] Optionally, the angle of the sector-shaped notch is 45 to 135 degrees. Since the diameters of different mounting shafts 2 are different, in order to enable different mounting shafts 2 to be used with the conveying roller assembly of the present invention, the angle of the notch portion 13 is between 45 and 135 degrees.

[0044] In an embodiment of the conveying roller 1 assembly of the cigarette making machine of the present invention, the angle of the sector-shaped notch is 60 degrees.

[0045] Optionally, the connecting member 3 is provided with a connecting hole 33, and the connecting hole 33 is correspondingly arranged with the mounting portion 12. By installing bolts on the fixing member and the mounting portion 12, the conveying roller 1 is connected to the connecting member 3, and thus the conveying roller 1 is fixed on the mounting shaft 2, which increases the stability of the conveying roller 1 installed on the mounting shaft 2.

[0046] Optionally, the inner sidewall of the connecting member 3 is in an arc shape and is connected to the outer peripheral wall of the mounting shaft 2. This setting makes the connection between the connecting member 3 and the mounting shaft 2 more fitting, ensuring that during operation, it has no impact on the circumferential movement of the conveying roller 1.

[0047] It should be noted that the connecting member 3 and the mounting shaft 2 can be integrally formed, or the connecting member 3 can be fixed to the mounting shaft 2 by bolts.

[0048] In an embodiment of the conveying roller 1 assembly of the cigarette making machine of the present invention, a tool holder 4 is further provided on the mounting shaft 2, and the tool holder 4 is provided on the outer peripheral wall of the mounting shaft 2. A cutting knife 5 is provided on the tool holder 4. When the conveying roller 1 rotates to convey the transparent paper, it simultaneously drives the cutting knife 5 on the tool holder 4 to rotate at the same rate and cuts the transparent paper to form a cut drawstring, which is used for packaging the cigarette pack and facilitates the user to open the package.

[0049] To facilitate the installation of the tool holder 4, the tool holder 4 is in a semi-circular ring structure and is fixed to the mounting shaft 2 by bolts.

[0050] Furthermore, the cutting knife 5 is a U-shaped cutting knife 5. The tool holder 4 is provided between two conveying rollers 1 and is connected to the two connecting members 3; or the inner sidewall of the tool holder 4 is connected to the outer sidewall of the connecting member 3.

[0051] Optionally, the conveying roller 1 includes a first conveying roller 14 and a second conveying roller 15. The first conveying roller 14 and the second conveying roller 15 have the same diameter, and the thickness of the first conveying roller 14 is greater than the thickness of the second conveying roller 15.

[0052] The inner sidewalls of the mounting portions 12 of the first conveying roller 14 are respectively connected to the outer sidewalls of two adjacent connecting members 3, and the inner sidewall of the mounting portion 12 of the second conveying roller 15 is connected to the outer sidewall of one connecting member 3.

[0053] It should be explained that since the thickness of the transparent paper is very thin, if a single conveying roller 1 is used to convey the transparent paper, when the conveying roller 1 is worn or there is a slight error in the conveying speed of the transparent paper, it will cause the transparent paper to wrinkle or tear. By providing the first conveying roller 14 and the second conveying roller 15 to jointly convey the transparent paper, the situation of the transparent paper wrinkling or tearing is reduced.

[0054] Furthermore, multiple groups of the first conveying roller 14 and the second conveying roller 15 are provided on the mounting shaft 2. The distance between two adjacent connecting members 3 matches the thickness of the first conveying roller 14 and the second conveying roller 15.

[0055] In an embodiment of the conveying roller 1 assembly of the cigarette making machine of the present invention, the inner sidewall of the conveying roller 1 is connected to the outer sidewall of the connecting member 3.

[0056] The outer sidewall of the connecting member 3 is in an arc shape. The mounting portion 12 protrudes from the body 11 towards both sides of the body 11, and the inner sidewall of the mounting portion 12 is connected to the arc shape of the outer sidewall of the connecting member 3.

[0057] In the present invention, by setting the outer sidewall of the connecting member 3 to be in an arc shape and the mounting portion 12 to protrude from the body 11 towards both sides of the body 11, the mounting portion 12 has a certain extension length, and thus the inner sidewall of the mounting portion 12 is connected to the arc shape of the outer sidewall of the connecting member 3, facilitating the installation of the mounting portion 12 and the connecting member 3 and ensuring the stability of the installation.

[0058] In a specific embodiment, both ends of the mounting portion 12 of the first conveying roller 14 are respectively connected to two adjacent connecting members 3, and the mounting portion 12 of the second conveying roller 15 is connected to one connecting member 3. The mounting portion 12 has a plurality of mounting holes 121. The connecting member 3 is provided with a plurality of connecting holes 33 corresponding to the mounting holes 121.

[0059] In an embodiment of the conveying roller 1 assembly of the cigarette making machine of the present invention, the inner sidewall of the conveying roller 1 is connected to the outer sidewall of the connecting member 3.

The outer sidewall of the first connecting section 31 is in an arc shape, and the outer sidewall of the second connecting section 32 is in a straight line shape. The outer sidewall of the first connecting section 31 is connected to the mounting portion 12; the outer sidewalls of the two second connecting sections 32 are connected to the body 11 corresponding to the notch portion 13.

[0061] In the present invention, by setting the connecting member 3 to be composed of the first connecting section 31 and the second connecting section 32, the outer sidewall of the first connecting section 31 is connected to the mounting portion 12, and the outer sidewalls of the second connecting sections 32 are connected to the body 11 corresponding to the notch portion 13, so that the connecting member 3 is completely embedded in the mounting portion 12 and the notch portion 13, increasing the stability of the conveying roller 1 installed on the connecting member 3 and also increasing the convenience of the conveying roller 1 installed on the connecting member 3.

[0062] In this embodiment, both ends of the first connecting section 31 are respectively connected to the two second connecting sections 32. The inner sidewalls of the first connecting section 31 and the second connecting section 32 are in an arc shape and are connected to the mounting shaft 2. The inner sidewalls of the first connecting section 31 and the second connecting section 32 are in an arc shape with the same radius, and the two are smoothly connected in a transitional manner.

[0063] In an embodiment of the conveying roller 1 assembly of the cigarette making machine of the present invention, the conveying roller 1 is arranged between two adjacent connecting members 3.

[0064] Further, the notch portion 13 of the conveying roller 1 is connected to the mounting shaft 2, and the two side walls of the conveying roller 1 are respectively abutted against two adjacent connecting members 3.

[0065] In the present invention, by arranging the conveying roller 1 between two adjacent connecting members 3, the notch portion 13 of the conveying roller 1 is connected to the mounting shaft 2, and the two side walls of the conveying roller 1 are respectively abutted against two adjacent connecting members 3, so as to mount the conveying roller 1 on the mounting shaft 2, which further facilitates the installation of the mounting portion 12 and the connecting member 3 and further ensures the stability of the installation.
