For those skilled in the art, the specific meaning of the above terms in the present embodiment can be understood according to the specific circumstances.

[0033] At present, when detecting the moisture content of the filter rod, first, the operator needs to manually cut the filter rod into 10mm long filter rod segments, and then put them into the oven for baking. If the lengths of the filter rod segments are inconsistent, it will affect the baking effect, and ultimately affect the accuracy of the filter rod moisture content detection. In addition, manually cutting the filter rod is time-consuming and laborious, and the detection efficiency is low.

[0034] To solve the above technical problems, the present application provides a slitting device which can automatically cut the filter rod into filter rod segments with uniform length, avoiding the problem of large detection error caused by inconsistent length of the filter rod segments, not only improving the accuracy of the filter rod moisture content detection, but also saving manpower.

[0035] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail.

Drum 3 extends along the vertical direction, and drum 3 is arranged below bunker 2. Drum 3 can rotate around its own axis. Drum 3 is provided with a plurality of material holes 31 that penetrate drum 3 along the vertical direction. The diameter of the material hole 31 is greater than or equal to the diameter of the filter rod 6. The filter rod 6 output through the material guide pipe 7 can enter the material hole 31. Tray 4 is arranged below drum 3. There is a gap between tray 4 and drum 3. The filter rod 6 located in the material hole 31 can at least partially protrude from the material hole 31, and the lower end surface of the filter rod 6 can be in contact with the upper surface of the tray 4, as shown in Figure 3 . Cutter 5 is arranged on one side of drum 3. Cutter 5 can rotate around its own axis, and cutter 5 at least partially protrudes into the gap between tray 4 and drum 3. Cutter 5 is used to cut the filter rod 6.

[0037] With the above technical scheme, when it is necessary to cut the filter rod 6, the filter rod 6 in the bunker 2 is first transported into the material hole 31 on the drum 3 through the material guide pipe 7. Then, under the action of gravity, the filter rod 6 entering the material hole 31 can protrude from the lower side of the material hole 31 until the lower end surface of the filter rod 6 is in contact with the upper surface of the tray 4. Each filter rod 6 sequentially passes through the cutter 5 in the process of following the rotation of the drum 3. When the filter rod 6 passes through the cutter 5, the rotating cutter 5 will cut the part of the filter rod 6 protruding from the material hole 31 to form a filter rod segment. Under the action of gravity, the part of the filter rod in the material hole 31 that has not been cut will continue to move downward. With the rotation of the drum 3, when the filter rod 6 passes through the cutter 5 again, the cutter 5 will continue to cut the remaining filter rod 6. The distance between the cutter 5 and the upper surface of the tray 4 defines the length of the filter rod segment, so that the length of each filter rod segment can remain consistent. The slitting device provided in the present application cuts filter rod segments with consistent lengths, avoiding the problem of large detection errors caused by inconsistent lengths of filter rod segments, thereby improving the accuracy of filter rod moisture content detection and saving manpower.

The third motor 9 is arranged to drive the cutter 5 to rotate at a high speed, so that the cutting efficiency of the filter rod 6 is improved. The cutter 5 is disc-shaped, so that the cutting section of the filter rod 6 is neat, and the cutting quality of the filter rod 6 is improved.

The first motor 8 can drive the rotating shaft 10 to rotate around its own axis, thereby driving the rotating drum 3 and the tray 4 to rotate synchronously. This design avoids the problem that the filter rod 6 is damaged due to friction between the filter rod 6 and the tray 4. In addition, the position of the rotating drum 3 on the rotating shaft 10 is adjustable, so that the distance between the rotating drum 3 and the tray 4 can be changed by adjusting the position of the rotating drum 3 according to actual needs, so as to control the length of the filter rod segment formed by cutting the filter rod 6.
