Cutter structure for cutting polylactic acid fiber filter rods

Abstract

The present disclosure provides a cutter structure for cutting polylactic acid fiber filter rods and relates to the technical field of cigarette preparation. The cutter structure includes a cutter shaft and cutters, wherein the cutters include a middle cutter and side cutters, the middle cutter is round, and cutting edges of the side cutters are flush with an edge of the middle cutter; hardness of the middle cutter is higher than that of the side cutters, so that the tow middle cutter can be conveniently used for cutting lized tows that have been crystallized in the polylactic acid fiber filter rods; and the side cutters are detachably arranged on side faces of the middle cutter and used for preventing glyceryl triacetate from adhering to the side faces of the middle cutter. The cutter structure provided by the present disclosure is simple in arrangement, the two kinds of cutters are cooperatively arranged, the situation that blades are damaged when the middle cutter collides with random crystallization points in polylactic acid fiber tows is avoided due to high hardness of the middle cutter, the side cutters on the side faces can protect the middle cutter against glyceryl triacetate adhesion, the side cutters are detachably arranged, so as to be conveniently replaced, and therefore the whole structure has higher efficiency and stability for cutting the polylactic acid fiber filter rods.
