The filter rod 1 can pass through the cutting hole 3 in the first direction. The diameter of the cutting hole 3 can be set according to actual use requirements. Specifically, the diameter of the cutting hole 3 is greater than or equal to the outer diameter of the filter rod to facilitate smooth passage of the filter rod. The blade 21 at least partially protrudes from the circumference of the cutting hole 3 and is used to cut the wrapping layer when the filter rod passes through the cutting hole 3.

[0036] When testing the amount of plasticizer applied to a filter stick, the filter stick is first passed through the cutting hole 3 in a first direction. The cutting action of the blade 21 causes the filter stick's wrapping to be cut open along the stick's axis, exposing the stick's interior. A gas chromatograph is then used to measure the amount of plasticizer applied to the stick. The utility model can quickly cut the stick's wrapping, eliminating the need to manually tear the wrapping open, saving manpower and improving work efficiency.

[0037] Optionally, refer to Figure 2 and Figure 3 The cutting device further comprises a blade 2, on which a cutting edge 21 and a positioning hole 22 are provided.
