[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] like Figures 1 to 3 As shown, this embodiment provides a paper adjustment device that can be installed on a cigarette making machine unit to adjust the paper tension. Optionally, the paper is tipping paper. Of course, the paper can also be other types of paper, which is not specifically limited in this embodiment.

[0032] The paper adjustment device includes a guide block 1, a movable block 2, an adjustment rod assembly 3, and a paper guide block 4. An adjustment slot 11 is provided through the guide block 1 along a first direction (i.e., the X direction in the drawings). The bottom of the adjustment slot 11 is recessed downward to form a limit slot 12. Multiple limit slots 12 are provided, spaced apart along a second direction (i.e., the Y direction in the drawings), such that any two limit slots 12 can form a movement path with the adjustment slot 11. Optionally, the notches of the limit slots 12 are arcuate.

[0033] At the same time, the movable block 2 is slidably arranged on the guide block 1 along the second direction, and one end of the adjustment rod group 3 is hinged to the guide block 1, and the adjustment rod group 3 can move along the second direction and the third direction (i.e., the Z direction in the figure) so that the adjustment rod group 3 is engaged in the limiting groove 12, thereby limiting the movement path of the adjustment rod group 3 through the movable block 2, so that the adjustment rod group 3 can move stably between any two limiting grooves 12 and the adjustment groove 11 to form a movement path. Among them, the paper guide block 4 is sleeved on the outside of the adjustment rod group 3, and the paper is attached to the paper guide block 4. When the adjustment rod group 3 is engaged in the limiting groove 12 at different positions, the paper guide block 4 on the adjustment rod group 3 can tension the paper to different degrees, thereby adjusting the tension on the paper, thereby improving the gluing effect of the subsequent paper during gluing and other processes, and avoiding subsequent quality problems of the product. Specifically, the first direction, the second direction, and the third direction are arranged perpendicular to each other.

[0034] like Figure 1 and Figure 3 As shown, the adjustment rod assembly 3 includes an adjustment shaft 31, an adjustment sleeve 32, and a transmission arm 33. The adjustment sleeve 32 is rotatably mounted on the adjustment shaft 31, and the paper guide block 4 is mounted on the adjustment sleeve 32. One end of the transmission arm 33 is fixedly connected to the adjustment shaft 31, and the other end of the transmission arm 33 is rotatably hinged to the movable block 2. The adjustment shaft 31 extends along a first direction and is capable of being engaged in the limiting groove 12. Therefore, when the adjustment shaft 31 drives the transmission arm 33 to move relative to the movable block 2, and when the adjustment shaft 31 is engaged in the limiting groove 12, the rotation of the adjustment shaft 31 itself does not affect the adjustment sleeve 32, thereby avoiding affecting the paper guide block 4 on the adjustment sleeve 32. Optionally, the adjustment sleeve 32 can be fixed to the adjustment rod by screws.

[0035] At the same time, the adjustment lever assembly 3 also includes an adjustment member 34, which is connected to the end of the adjustment shaft 31 away from the transmission arm 33. The arrangement of the adjustment member 34 facilitates a worker to move the paper guide block 4 by holding the adjustment member 34. The adjustment member 34 also includes a stopper 341, which is used to stop the adjustment sleeve 32 in a first direction to prevent the adjustment sleeve 32 from being disengaged from the adjustment shaft 31. Optionally, the adjustment member 34 is movably connected to the adjustment shaft 31 in a first direction, and the adjustment sleeve 32 is movably sleeved outside the adjustment shaft 31 in the first direction. After the adjustment member 34 is moved relative to the adjustment shaft 31 in the first direction, the position of the stopper 341 can be adjusted, thereby allowing the adjustment sleeve 32 to move along the adjustment shaft 31 in the first direction, thereby facilitating adjustment of the position of the paper guide block 4 and preventing the paper guide block 4 from deviating from the position relative to the paper, thereby preventing the paper from flanging.

[0036] Furthermore, the paper guide blocks 4 include two, spaced apart along the first direction. The two paper guide blocks 4 support the paper, eliminating the need for a single-piece paper guide block, reducing weight and meeting lightweight requirements while also supporting both edges of the paper. Optionally, the paper guide blocks 4 include position-limiting protrusions 41, with the paper abutting and limiting position located between the position-limiting protrusions 41 of the two paper guide blocks 4. The two position-limiting protrusions 41 can be used to position the paper abutting and preventing the paper edges from separating from the paper guide blocks 4. Furthermore, optionally, the paper guide blocks 4 are movably sleeved outside the adjustment lever assembly 3 along the first direction, allowing the spacing between the position-limiting protrusions 41 of the two paper guide blocks 4 to be adjusted to accommodate paper of varying widths.

[0037] like Figure 1 and Figure 2 As shown, the top of the adjustment slot 11 is recessed upward with a guide rail slot 13, and the adjustment shaft 31 can abut against the slot wall of the guide rail slot 13 and move along the second direction, so that the adjustment shaft 31 can reduce the difficulty of movement by moving in the guide rail slot 13, thereby avoiding the adjustment shaft 31 colliding with the slot opening of the limit slot 12 and causing damage to the paper adjustment device. Optionally, a spring plate 21 is rotatably provided on the movable block 2, and the spring plate 21 has a hook 211. A placement slot 331 and a slot 332 are provided at one end of the transmission arm 33 close to the movable block 2. When the adjusting shaft 31 is located in the adjusting through slot 11 and the limit slot 12, the hook 211 is placed in the placement slot 331. At this time, the spring plate 21 and the hook 211 will not affect the movement of the adjusting shaft 31. When the adjusting shaft 31 is located in the guide rail slot 13, the hook 211 is engaged with the slot 332. At this time, the spring plate 21 can clamp the adjusting shaft 31 through the hook 211, assisting the staff to move the adjusting shaft 31, and avoiding shaking of the adjusting shaft 31 when moving in the guide rail slot 13, which may cause paper misalignment.

[0038] This embodiment also provides a cigarette making machine, including the paper adjusting device as described above. The cigarette making machine also includes a cigarette making machine unit. The paper adjusting device can be set on the cigarette making machine unit. By using the paper adjusting device as described above, the cigarette making machine can make the paper guide block 4 on the adjustment rod group 3 tension the paper to different degrees, so as to adjust the tension of the paper, thereby improving the subsequent gluing effect of the paper during gluing and other processes, and avoiding subsequent quality problems of the product.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
