[0018] like Figure 1 and Figure 6 As shown, a bottom knife fine-adjusting slitting device for cigarette paper comprises a bottom knife roller 1 and a blade roller 2, one end of the bottom knife roller 1 is sleeved and fixedly connected with a fixing sleeve 3, a plurality of mounting sleeves 4 are sleeved and slidably connected on the bottom knife roller 1, a bottom knife 5 is arranged at one end of the mounting sleeve 4, an adjusting component 6 for adjusting the distance between two adjacent bottom knives 5 is arranged on the bottom knife roller 1 between two adjacent mounting sleeves 4, and a threaded sleeve 7 for positioning the plurality of mounting sleeves 4 is sleeved and threadedly connected on the other end of the bottom knife roller 1 located at the fixing sleeve 3; A plurality of cutting knives 8 are arranged on the blade roller 2, and the cutting knives 8 include a sleeve portion 801 sleeved on the blade roller 2, and a cutting portion 802 arranged along the circumferential side wall of the sleeve portion 801, and also include a positioning component for positioning the sleeve portion 801. One end of the blade roller 2 and the bottom knife roller 1 are both provided with gears 9 that mesh with each other.

[0019] During production and processing, according to the environmental conditions and the shrinkage and expansion of the cigarette paper itself, the threaded strip is loosened, and the distance between two adjacent bottom knives is adjusted by adjusting the component 6, and the position of the cutting knife 8 is adjusted at the same time, so that the cutting position of the cigarette paper can be quickly adjusted to ensure the cutting accuracy of the cigarette paper in different environments.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, one end of the mounting sleeve 4 is provided with a first sleeve groove 401 along its circumferential surface, the bottom knife 5 is sleeved in the first sleeve groove 401, and one end of the bottom knife 5 facing the first sleeve groove 401 is provided with a bottom knife groove 501 along its circumferential surface, a cutting groove cooperating with the cutting portion 802 is formed between the bottom knife groove 501 and the first sleeve groove 401, the cutting portion 802 extends into the cutting groove, and the cigarette paper passes between the bottom knife roller 1 and the blade roller 2 to cut the cigarette paper.

[0021] like Figure 5 As shown, the adjustment component 6 includes an adjusting female sleeve 10 which is sleeved and slidably connected to the bottom knife roller 1, and one end of the adjusting female sleeve 10 is provided with a second sleeve groove 101 along its circumferential surface, and the surface of the second sleeve groove 101 is provided with an external thread 102. The adjusting female sleeve 10 is sleeved with an adjusting sub-sleeve 11 at the second sleeve groove 101, and the circumferential inner wall of the adjusting sub-sleeve 11 is provided with an internal thread 111 that matches the external thread 102. The two end surfaces of the adjusting female sleeve 10 and the adjusting sub-sleeve 11 are respectively abutted against the mounting sleeve 4 and the bottom knife, and the overall length of the adjusting female sleeve 10 and the adjusting sub-sleeve 11 is adjusted by rotating the adjusting sub-sleeve 11 to adjust the distance between two adjacent cutting grooves.

[0022] like Figure 1 As shown, the bottom knife roller 1 is provided with a positioning sleeve 12 between the threaded sleeve 7 and the mounting sleeve 4. After a number of mounting sleeves 4 and adjusting female sleeves 10 are sequentially mounted on the bottom knife roller 1, the positioning sleeve 12 is mounted to position the bottom knife 5 on the end mounting sleeve 4 and form a cutting groove between the bottom knife 5 and the threaded sleeve 7. Finally, the threaded sleeve 7 is screwed into the end of the bottom knife roller 1 and pressed against the positioning sleeve 12, so that the various components on the bottom knife roller 1 are pressed against each other to ensure its stability during cutting.

[0023] like Figure 2 , Figure 5 and Figure 7 As shown, the circumferential surface of the bottom knife roller 1 is provided with a limit strip 13 along its length direction, and the circumferential inner walls of the mounting sleeve 4 and the adjusting female sleeve 10 are provided with a limit groove 14 which slides on the limit strip 13 to prevent the mounting sleeve 4, the adjusting female sleeve 10 and the positioning sleeve 12 from rotating relative to the bottom knife roller 1, thereby further improving its stability during operation.

[0024] like Figure 1 and Figure 5 As shown, the circumferential outer wall of the adjusting sub-sleeve 11 is evenly provided with a plurality of first adjusting holes 15 along its circumferential direction, and the circumferential outer wall of the threaded sleeve 7 is evenly provided with a plurality of second adjusting holes 16 along its circumferential direction, so as to facilitate the insertion of the adjusting rod into the first adjusting hole 15 and the second adjusting hole 16, and facilitate the rotation of the adjusting sub-sleeve 11 and the threaded sleeve 7.

[0025] like Figure 8 and Fig. 9 As shown, the circumferential surface of the blade roller 2 is provided with a plurality of slide grooves corresponding to the cutting knives 8, and the slide grooves are perpendicular to the length direction of the blade roller 2. A positioning rod 17 is slidably connected in the slide grooves. A sliding groove perpendicular to and connected to the slide grooves is provided inside the blade roller 2. The positioning assembly includes a positioning rod 17 slidably connected in the slide grooves. The bottom end of the positioning rod 17 is arranged in an inclined surface. The sliding rod 18 is provided with a plurality of triangular grooves matching the inclined surface of the end of the positioning rod 17. It also includes a driving member for driving the sliding rod 18. After the position of the cutting knife 8 is adjusted, the sliding rod 18 is driven to slide by the driving member. Under the action of the triangular grooves and the inclined surface of the end of the positioning rod 17, the positioning rod 17 is pushed to move upward and press against the circumferential inner wall of the sleeve 801 to simultaneously position all the cutting knives 8.

[0026] like Fig. 9 As shown, a threaded groove connected to the sliding groove is provided on the circumferential surface of one end of the blade roller 2, and the driving member is specifically a bolt 19 arranged in the threaded groove, and the circumferential side of the bottom end of the bolt 19 is arranged in an inclined surface, and a spring 20 is arranged inside the sliding groove located at the other end of the bolt 19, and the two ends of the spring 20 are fixedly connected to the end inner wall of the sliding groove and the end of the sliding rod 18.

[0027] like Fig. 9 As shown, the bolt 19 is not yet tightened. By tightening the bolt 19, the sliding rod 18 is pushed to slide toward one end of the spring 20. The spring 20 is compressed and drives the positioning rod 17 to slide toward the outside of the slide groove to position the cutting knife 8. When the position of the cutting knife 8 needs to be adjusted, the bolt 19 is loosened and the sliding rod 18 is pushed to slide away from one end of the spring 20 under the elastic force of the spring 20, so that the positioning rod 17 is no longer tightly against the sleeve portion 801. When the adjustment component 6 is adjusted, when the position of the cutting groove changes, the position of the cutting knife 8 can be adjusted at the same time. After the adjustment is completed, the bolt 19 is tightened again to fix the position of the cutting knife 8.
