the cutter unit 52 comprises a cutter rotating shaft 521 and a cutting sheet 522, the axial direction of the cutter rotating shaft 521 is the same as the axial direction of the feeding conveying roller 51, the cutter rotating shaft 521 is rotatably arranged on the frame 53 through a bearing, the cutting sheet 522 is sleeved on the cutter rotating shaft 521, and the cutting sheet 522 is correspondingly clamped in the cutter groove 512.

When the drawing device 4 passes through the filter stick from the storage tank 511, the motor drives the cutter rotating shaft 521, and at this time, the slice 522 on the cutter rotating shaft 521 rotates along with the cutter rotating shaft 521 to cut the filter stick in the storage tank 511.

When the device is used, tows are gathered into a long rope shape under the action of the opener 1 and enter the filter stick forming device 2 to form a filter stick, the first heat conduction pipe 2123 uniformly conducts heat to the formed filter stick to enable the outer surface of the filter stick to be bonded smoothly and uniformly, and the second heat conduction pipe 2223 uniformly conducts cold to the formed filter stick to enable the outer surface of the bonded filter stick to be condensed smoothly and uniformly shaped.

Meanwhile, the double-layer grooved paper formed by the unwinding device 6 enters the filter stick forming device 2 and then is wrapped on the outer wall of the filter stick, when the formed filter stick enters the material passing groove 413, a long-strip-shaped cloth tape unwound by the cloth tape unwinding device 6 (not shown) enters the material passing groove 413 through the tapered opening 414 under the guidance of the guide wheel 42, and the cloth tape is rolled into a hollow cylindrical shape and is wrapped on the outer surface of the double-layer grooved paper of the filter stick.

When the drawing device 4 passes through the filter stick from the storage tank 511, the motor drives the cutter rotating shaft 521, and at this time, the slice 522 on the cutter rotating shaft 521 rotates along with the cutter rotating shaft 521 to cut the filter stick in the storage tank 511.

The invention is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the invention is not limited to the specific details, representative apparatus, and examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
