Cutting device for a tobacco industry rod making machine and method for adjusting the position of the or each grinding wheel of a grinding device in a cutting device for a tobacco processing machine extrusion machine

摘要

The invention relates to a cutting device (10) for a rod machine in the tobacco processing industry, comprising a knife holder (11) with at least one knife holder (12), in each of which a knife (13) adjustable in the radial direction is arranged, the knife holder (11 ) a drive shaft (14) mounted in a housing (16) and a drive (15) for rotatingly driving the knife carrier (11) about an axis of rotation A is assigned, an adjusting device for adjusting the knife carrier (11) to different formats, such that the angle β formed between the axis of rotation A of the drive shaft (14) of the knife carrier (11) and the or each strand (17) to be cut, and a grinding device (18) for grinding the or each knife (13) during the operation of the Cutting device (10), the grinding device (18) having a grinding wheel holder (19) with at least one rotating by means of a drive (21) e has an axis of rotation B drivable grinding wheel (20) and the grinding wheel holder (19) is arranged stationary in the area of the knife carrier (11) in such a way that the or each knife (13) comes into contact with the or each grinding wheel by the rotation of the knife carrier (11) (20), which is characterized in that the grinding device (18) has a mechanism for automatically adjusting the or each grinding wheel (20) in the longitudinal direction of the axis of rotation B of the grinding wheel (20). Furthermore, the invention relates to a corresponding method.
