[0017] The technical solutions of the preferred embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them, and the various embodiments and technical features can be combined with each other without conflict. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection claimed in this application.

[0018] The double-length filter cigarettes with the tipping paper glued are transported by the transfer drum until they are transported to the slitting drum. A cutter is provided at the midline position of the circumference of the slitting drum. When the double-length filter cigarettes are driven to the cutter by the slitting drum, the cutter cuts along the middle part of the cigarette, and cuts the double-length filter cigarettes into two ordinary cigarettes of the same length. However, the cigarettes may be axially offset during the transmission process, and the cutter cannot cut along the middle part of the axially offset cigarettes, resulting in different lengths of the two ordinary cigarettes being cut, which affects the appearance quality of the cigarettes.

[0019] In view of the above problems, the embodiments of the present application provide a cigarette axial positioning device. The cigarette axial positioning device can be used for axial positioning when cutting double-length filter cigarettes. It can be understood that the cigarette axial positioning device can also be used in various scenarios where axial deviation occurs during the cigarette transmission process to correct the axial position of the cigarette.

[0020] Figure 1 FIG. 1 is a schematic diagram of the structure of a cigarette axial positioning device provided in an embodiment of the present application at an angle. Figure 1 As shown, the cigarette support axial positioning device may include a mounting shaft 1 , a fixing assembly, a first sliding block 2 and a second sliding block 3 .

[0021] The mounting shaft 1 can be used as a mounting base for other components. The shape of the mounting shaft 1 can be cylindrical, prismatic, or can be a shaft body with a cross section of other shapes.

[0022] The fixed component is arranged on the mounting shaft 1, and at least a part of the fixed component is fixedly connected to the mounting shaft 1. The fixed component can serve as a fulcrum for adjusting the first slider 2 and the second slider 3. The first slider 2 and the second slider 3 can realize position adjustment on the mounting shaft 1 by changing the distance from the fixed component.

[0023] The first slider 2 is slidably disposed on the mounting shaft 1, and the first slider 2 can slide along the extension direction of the mounting shaft 1. The first slider 2 can be sleeved on the mounting shaft 1, or can be slidably connected to the mounting shaft 1 through a sliding structure such as a slide groove or a slide rail. The first slider 2 is connected to the fixed component with an adjustable spacing, that is, the first slider 2 is connected to the fixed component, and the spacing between the first slider 2 and the fixed component can be adjusted. For example, the first slider 2 and the fixed component can be connected through a screw or a length-adjustable connection structure. A first positioning piece 8 is provided on the first slider 2, and the first positioning piece 8 is used to axially position the cigarette. The first positioning piece 8 can be installed on the first slider 2 through a positioning piece screw 10. Of course, it can also be fixed to the first slider 2 by welding, bonding, etc. In other embodiments, the positioning piece can be integrally formed with the slider. In some embodiments, the shape of the first positioning piece 8 can be arc-shaped to adapt to the shape of the drum wheel.

[0024] The second slider 3 is slidably arranged on the mounting shaft 1, and the second slider 3 can slide along the extension direction of the mounting shaft 1. The second slider 3 can be sleeved on the mounting shaft 1, and can also be slidably connected to the mounting shaft 1 through a sliding structure such as a slide groove or a slide rail. The second slider 3 is connected to the fixed component with an adjustable spacing, that is, the second slider 3 is connected to the fixed component, and the spacing between the second slider 3 and the fixed component can be adjusted. For example, the second slider 3 and the fixed component can be connected through a screw or a length-adjustable connection structure. A second positioning piece 9 is provided on the second slider 3, and the second positioning piece 9 is used for axial positioning of the cigarette. The second positioning piece 9 can be installed on the second slider 3 through a positioning piece screw 10. Of course, it can also be fixed to the second slider 3 by welding, bonding, etc. In other embodiments, the positioning piece can be integrally formed with the slider. For example, the shape of the second positioning piece 9 can be arc-shaped to adapt to the shape of the drum wheel.

[0025] The first positioning piece 8 and the second positioning piece 9 are arranged opposite to each other, and a gap is formed between the first positioning piece 8 and the second positioning piece 9 for axial positioning of the cigarette. When a cigarette with axial displacement enters the gap between the first positioning piece 8 and the second positioning piece 9, it can be guided by the first positioning piece 8 or the second positioning piece 9, so as to correct the axial position of the cigarette. By adjusting the position of the first slider 2 and / or the second slider 3, the position and size of the gap between the first positioning piece 8 and the second positioning piece 9 can be changed, so that the cigarette can move to a predetermined position in the axial direction. The width of the narrowest part of the gap between the first positioning piece 8 and the second positioning piece 9 can be adjusted to be equal to or slightly larger than the length of the cigarette, so that the axial position of the cigarette can be corrected more accurately.

[0026] The cigarette axial positioning device provided in the embodiment of the present application axially positions the cigarette through the gap between the first positioning piece 8 and the second positioning piece 9, so that the cigarette that has been axially offset during the transmission process can return to the predetermined axial position, thereby facilitating the cutter to accurately cut the cigarette and ensure the appearance quality of the cigarette; at the same time, the first slider 2 and the second slider 3 with adjustable position can change the position and size of the gap between the first positioning piece 8 and the second positioning piece 9, so as to adapt to cigarettes of various specifications.

[0027] In some embodiments, the first positioning piece 8 includes a first guide positioning segment, the second positioning piece 9 includes a second guide positioning segment, and the first guide positioning segment and the second guide positioning segment form a bell-shaped gap. In this embodiment, the first guide positioning segment and the second guide positioning segment form a bell-shaped gap, and the entrance width of the bell-shaped gap can be greater than the length of the cigarette, which can facilitate the axially offset cigarette to enter the gap between the first positioning piece 8 and the second positioning piece 9, and prevent the cigarette from hitting the ends of the first positioning piece 8 and the second positioning piece 9, affecting the axial position correction of the cigarette by the cigarette axial positioning device. The first guide positioning segment and the second guide positioning segment can be a sheet structure with uneven thickness, or a sheet structure with different extension directions, to form a bell-shaped gap.

[0028] In some embodiments, the first positioning piece 8 also includes a first cutting positioning segment, and the first cutting positioning segment and the first guide positioning segment are connected to each other in a staggered manner; the second positioning piece 9 also includes a second cutting positioning segment, and the second cutting positioning segment and the second guide positioning segment are connected to each other in a staggered manner, and the staggered direction of the first cutting positioning segment relative to the first guide positioning segment is opposite to the staggered direction of the second cutting positioning segment relative to the second guide positioning segment; the first cutting positioning segment and the second cutting positioning segment are respectively connected to the ends of the narrowest part of the bell-shaped gap formed by the first guide positioning segment and the second guide positioning segment, and the gap formed by the first cutting positioning segment and the second cutting positioning segment is larger than the narrowest part of the bell-shaped gap.

[0029] It can be understood that in the process of the cutter cutting the double-length filter cigarettes, the cutter cuts into the double-length filter cigarette and cuts the double-length filter cigarette into two ordinary cigarettes. At this time, the cutter is still between the two ordinary cigarettes. Since the cutter has a certain thickness, the two ordinary cigarettes are squeezed by the cutter, causing the cigarettes to move axially away from the cutter.

[0030] In this embodiment, the cutting positioning segment and the guiding positioning segment can form a stepped shape, and the gap between the two cutting positioning segments is larger than the narrowest part of the gap between the two guiding positioning segments. The cigarette can complete axial positioning in the gap between the first guiding positioning segment and the second guiding positioning segment, and then enter the gap between the first cutting positioning segment and the second cutting positioning segment, and complete the cutting of the cigarette in the gap between the first cutting positioning segment and the second cutting positioning segment.

[0031] In this embodiment, the gap between the first cutting positioning section and the second cutting positioning section reserves space for the axial movement of the cigarette caused by the extrusion of the cutter after the cigarette is cut, thereby preventing the end of the cigarette used for lighting from being squeezed and damaged by the positioning piece, thereby further ensuring the quality of the cigarette.

[0032] In some embodiments, the cigarette support axial positioning device also includes a first adjusting rod 5 and a second adjusting rod 6. The first adjusting rod 5 can be rotatably connected to the fixed component along its own axis, and the first adjusting rod 5 is threadedly connected to the first slider 2; the second adjusting rod 6 can be rotatably connected to the fixed component along its own axis, and the second adjusting rod 6 is threadedly connected to the second slider 3; the first adjusting rod 5 and the second adjusting rod 6 are axially limited by the fixed component.

[0033] In this embodiment, the first slider 2 and the second slider 3 are respectively connected to the fixed component with an adjustable spacing through the first adjusting rod 5 and the second adjusting rod 6. When the first adjusting rod 5 and the second adjusting rod 6 are arranged on the fixed component, they can rotate around their own axes and be axially limited by the fixed component. The first adjusting rod 5 and the second adjusting rod 6 are respectively threadedly connected to the first slider 2 and the second slider 3. At this time, by rotating the first adjusting rod 5 and the second adjusting rod 6, the axial positions of the first slider 2 and the second slider 3 on the first adjusting rod 5 and the second adjusting rod 6 can be adjusted, thereby realizing the position adjustment of the first slider 2 and the second slider 3.

[0034] In some embodiments, the fixing assembly includes a fixing block 16 and a third slider 4, wherein the fixing block 16 is disposed on the mounting shaft 1; the third slider 4 is slidably disposed on the mounting shaft 1, and the third slider 4 can slide along the extension direction of the mounting shaft 1, and the third slider 4 is connected to the fixing block 16 with an adjustable spacing; the first adjusting rod 5 and the second adjusting rod 6 can be rotatably connected to the third slider 4 along their own axes and are axially limited by the third slider 4. The fixing block 16 can be sleeved on the mounting shaft 1, and a fixing bolt 11 can be threadedly connected to the fixing block 16. When the fixing bolt 11 is tightened, the position of the fixing block 16 is fixed; when the fixing bolt 11 is loosened, the fixing block 16 can be adjusted in position or slid and removed from the mounting shaft 1.

[0035] In this embodiment, the third slider 4 can be position-adjusted with the fixed block 16 as a fulcrum. When the position of the third slider 4 changes, it can drive the first slider 2 and the second slider 3 connected to the third slider 4 through the first adjusting rod 5 and the second adjusting rod 6 to move together, thereby realizing the overall adjustment of the gap between the first positioning plate 8 and the second positioning plate 9, simplifying the adjustment method and facilitating fine-tuning of the position.

[0036] In some embodiments, a first screw hole and a second screw hole are provided on the third slider 4; the first screw hole is connected to the installation position of the first adjustment rod 5, and a first set screw 13 is provided in the first screw hole; the second screw hole is connected to the installation position of the second adjustment rod 6, and a second set screw 12 is provided in the second screw hole. In this embodiment, the first set screw 13 and the second set screw 12 can respectively abut against the first adjustment rod 5 and the second adjustment rod 6 by rotating, thereby limiting the rotation of the first adjustment rod 5 and the second adjustment rod 6, ensuring the stability of the first positioning plate 8 and the second positioning plate 9; when the first set screw 13 and the second set screw 12 are loosened, the first adjustment rod 5 and the second adjustment rod 6 can rotate normally, thereby realizing the position adjustment of the first positioning plate 8 and the second positioning plate 9.

[0037] In some embodiments, the fixing assembly further includes a third adjusting rod 7, which can be rotatably connected to the fixing block 16 along its own axis, and the third adjusting rod 7 is threadedly connected to the third slider 4. The third slider 4 is connected to the fixing block 16 with an adjustable spacing through the third adjusting rod 7. When the third adjusting rod 7 is set on the fixing block 16, it can rotate around its own axis and be axially limited by the fixing block 16. The third adjusting rod 7 is threadedly connected to the third slider 4. At this time, by rotating the third adjusting rod 7, the axial position of the third slider 4 on the third adjusting rod 7 can be adjusted, thereby realizing the position adjustment of the third slider 4.

[0038] In some embodiments, a third screw hole is provided on the fixing block 16, the third screw hole is communicated with the installation position of the third adjusting rod 7, and a third set screw 14 is provided in the third screw hole. The third set screw 14 can abut against the third adjusting rod 7 by rotating, thereby limiting the rotation of the third adjusting rod 7 and ensuring the stability of the third slider 4.

[0039] In some embodiments, guide keys 15 are respectively provided at the installation positions of the first slider 2, the second slider 3 and the third slider 4 on the installation shaft 1, and guide grooves corresponding to the guide keys 15 are respectively provided on the first slider 2, the second slider 3 and the third slider 4. The guide keys 15 and the guide grooves can prevent the first slider 2, the second slider 3 and the third slider 4 from rotating on the installation shaft 1, thereby ensuring the stability of the cigarette holder axial positioning device.
