[0002] When producing cigarette filter rods, a cutter is required to cut the double-length filter rod into two equal-length finished filter rods at the midpoint of its length. When cutting the filter rods, a drum wheel is used to transport the double-length filter rod so that the double-length filter rod moves in a direction perpendicular to its own axis. When the double-length filter rod passes through the cutter, it can be cut into two finished filter rods by the cutter. In order to make the lengths of the two finished filter rods equal, it is necessary to set limit plates on both sides of the drum wheel to adjust its own position along the axial direction of the double-length filter rod so that the midpoint of the length of the double-length filter rod is aligned with the cutter. Since different types of cigarettes require finished filter rods of different lengths, the lengths of the double-length filter rods used are also different. In the prior art, when the length specifications of the filter rods produced in the next batch are different from those of the filter rods produced in the previous batch, it is necessary to disassemble the filter rod cutting device and replace the drum wheel, limit plates and part of the frame. After completing the replacement work, the cutting work of the next batch can be continued. Therefore, it is more complicated and time-consuming to adjust the segmentation length of the filter rod by replacing the components of the filter rod cutting device. Utility Model Content

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] The embodiment of the utility model provides a filter rod cutting device, such as Figure 1As shown, it includes a frame 1, a drum 2, a cutter 5 and two limit plates 6. The drum 2 is arranged on the frame 1, and the drum 2 can rotate around its own axis. The outer circumference of the drum 2 is provided with a receiving groove 3 extending in a first direction and a cutter groove 4 extending in its circumferential direction. Figure 1 and Figure 2 The X direction is shown in the middle) is the axial direction of the drum 2, and the receiving groove 3 is used to receive the filter rod to be cut. The drum 2 can move along the conveying direction ( Figure 2 The filter rod is transported (as shown in the R direction). The cutter 5 is detachably mounted on the frame 1, and the blade of the cutter 5 extends into the cutter groove 4. The cutter 5 is used to cut the filter rod to be cut. In this embodiment, the filter rod to be cut can be a double-length filter rod. When the double-length filter rod runs to the cutter 5 with the rotation of the drum 2, the cutter 5 cuts the double-length filter rod to obtain two finished filter rods. Two limit plates 6 are detachably mounted on the frame 1, and the two limit plates 6 are arranged on both sides of the drum 2 along a first direction. The limit plates 6 are used to adjust the position of the double-length filter rod along the first direction, and the spacing between each limit plate 6 and the cutter 5 along the first direction can be adjusted.

[0036] By adopting the above technical solution, by arranging adjustable limit plates 6 on both sides of the drum 2, it is easy to adjust the distance between each limit plate 6 and the cutter 5, and the distance between the two limit plates 6. The distance between the two limit plates 6 can limit the overall length of the double-length filter rod. The spacing between each limit plate 6 and the cutter 5 can limit the length of the two finished filter rods obtained by cutting. When the double-length filter rod needs to be cut, it is only necessary to adjust the position of the limit plate along the axial direction of the drum to limit the two ends of the double-length filter rod so that the position to be cut of the double-length filter rod is aligned with the cutter. The cumbersome process of disassembling and replacing the limit plates 6, the bracket and the cutting drum 2 in the prior art is avoided, which simplifies the work of adjusting the length of the filter rod and improves production efficiency. In addition, the user can also adjust the distance between the two limit plates 6 and the cutter 5 respectively: in normal production, the distance between the two limit plates 6 and the cutter 5 is adjusted to an equal distance, so that two finished filter rods of equal length can be obtained; in abnormal production, for example, to cut a longer recycled filter rod into a shorter finished filter rod, the user can adjust the distance between the two limit plates 6 and the cutter 5 to different distances to cut a finished filter rod from the recycled filter rod. In order to clearly describe the structure of the filter rod cutting device, the following embodiment only describes the case of cutting a double-length filter rod into two finished filter rods of equal length.

Along the conveying direction, the distance between the guide plate 7 and the cutter 5 gradually decreases. When the drum 2 carries the double-length filter rod from the inlet end into between the two limit plates 6, the guide plate 7 can guide the double-length filter rod to move along the first direction, so that the length midpoint of the double-length filter rod is aligned with the cutter 5.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, the frame 1 includes a main body 8 and a crossbeam 9, the drum 2 is arranged on the main body 8, and the crossbeam 9 extends along the first direction.

A first adjuster 12 is arranged between the first limit plate 10 and the main body 8, and a second adjuster 16 is arranged between the second limit plate 11 and the crossbeam 9. The first adjuster 12 is used to adjust the position of the first limit plate 10 along the first direction to adjust the distance between the first limit plate 10 and the cutter 5. The second adjuster 16 is used to adjust the position of the second limit plate 11 along the first direction to adjust the distance between the second limit plate 11 and the cutter 5.

[0039] Furthermore, if Figure 1 and Figure 2 As shown, the first adjuster 12 includes a mandrel 14, a sleeve 15 and a first bolt 18. The mandrel 14 is arranged on the main body 8, and the mandrel 14 extends in the first direction. A plurality of first blind holes are arranged on the outer circumference of the mandrel 14. The end of the sleeve 15 is connected to the first limit plate 10, and the sleeve 15 is sleeved on the mandrel 14 and can move in the first direction relative to the mandrel 14. A first threaded hole is arranged on the outer circumference of the sleeve 15. The first bolt 18 is threadedly matched with the first threaded hole. When the first bolt 18 is tightened, its end can be inserted into the blind hole to limit the position of the sleeve 15 and the first limit plate 10. The user can adjust the distance between the first limit plate 10 and the main body 8, that is, adjust the spacing between the first limit plate 10 and the cutter 5 by connecting the first bolt 18 to different first blind holes.

[0040] Furthermore, if Figure 1 and Figure 2 As shown, there are two first adjusters 12, which are arranged in sequence and spaced apart along the conveying direction, so as to prevent the first limit plate 10 from rotating around the axis of the core shaft 14 when only one first adjuster 12 is used, thereby improving stability.

[0041] Furthermore, if Figure 1 and Figure 2As shown, the cross-section of the crossbeam 9 is rectangular, and the crossbeam 9 is provided with a plurality of second blind holes spaced apart along the first direction, and the second adjuster 16 includes a slider 13 and a second bolt. The slider 13 is provided with a square hole extending along the first direction, and the square hole is sleeved on the crossbeam 9. The slider 13 can move along the first direction relative to the crossbeam 9, and the slider 13 is provided with a second threaded hole 20. The second bolt is threadedly matched with the second threaded hole 20. When the second bolt is tightened, its end is inserted into the second blind hole to limit the position of the slider 13 and the second limit plate 11. The user can adjust the spacing between the second limit plate 11 and the cutter 5 by connecting the second bolt to different second blind holes.

[0042] Furthermore, if Figure 2 As shown, the cross beam 9 is also provided with a bracket set 22, the bracket set 22 is located below the drum 2, and the bracket set 22 is provided with an arc surface 23, the axis of the arc surface 23 coincides with the axis of the drum 2, and when the filter rod passes through the arc surface 23, the arc surface 23 contacts the circumferential surface of the filter rod in the receiving groove 3, thereby preventing the double-length filter rod from falling out of the receiving groove 3.

[0043] Furthermore, if Figure 2 As shown, there are two bracket groups 22, and the two bracket groups 22 are mirror-imaged on both sides of the cutter 5 along the first direction, and the bracket group 22 includes a plurality of bracket pieces 24 arranged at intervals along the first direction, and the arc surface 23 is arranged on the bracket piece 24. Therefore, when the double-length filter rod is supported by the arc surface 23, the force can be evenly applied, and the filter rod position deviation or falling from between the two bracket pieces 24 caused by uneven force can be prevented.

[0044] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
