Problems solved by technology

[0004] The disadvantage of such a regrinding of the cutting knife is that sparks are produced during the grinding process, which should in principle be reduced to a minimum, because in extreme cases, parts of the machine itself can be damaged by flying sparks or the product strip or even set it on fire
Furthermore, it has been shown that burrs are produced on the cutting edges during regrinding of the cutting knives, and that burrs, despite the grinding of the cutting edges, lead to irregularities in the cut surface of rod-shaped products.

Embodiment Construction

[0024] exist Figure 1a and 1bIn the figure, a cutting device 1 can be seen with a knife holder 14 which can be placed in rotation, on which two cutting knives 2 and 3 are clamped. Furthermore, a grinding device 15 is arranged on the cutting device 1 , fixed relative to the knife holder 14 , with a grinding wheel 4 , the grinding surface of which is oriented at an angle relative to the axis of rotation of the knife holder 14 . The grinding device 15 includes an electric motor, by means of which the grinding wheel 4 can be driven in rotation. The cutting knives 2 and 3 can be pivoted additionally relative to the knife holder 14 for producing cuts perpendicular to the feed direction of the rod-shaped product, wherein the rotary movement of the cutting knives 2 and 3 is carried out by means of a not shown in the knife holder 14 organization to trigger. Furthermore, a protective device 6 is provided, by means of which the operator is to be prevented from inadvertently reaching i...

Abstract

The invention relates to a cutting device and a cutting blade for cutting rod-shaped products of tobacco processing industry. The cutting device (1) has at least one rotating blade holder (14) provided with at least one cutting blade (2, 3). The cutting blade (2, 3) has a cutting edge (9, 9a, 9b) and two side surfaces (7, 8) adjacent to the cutting edge (9, 9a, 9b), wherein at least one of the side surfaces (7, 8) of the cutting blade (2, 3) has a coating (13) which can improve surface hardness. Additionally, the invention relates to a cutting blade (2, 3) used in the cutting device (1), wherein the cutting blade (2, 3) is replaceable.

Description

technical field [0001] The invention relates to a cutting device and a cutting knife for cutting rod-shaped products of the tobacco processing industry having the features stated in the preamble of claim 1 . Background technique [0002] Rod-shaped products of the tobacco processing industry are, for example, cigarettes, cigarillos or filters in which the tobacco is held together stably by wrapping materials such as paper and in which the filter is arranged. For the production of rod-shaped products, modern forming machines are used which include a working step with a cutting device in which the rod-shaped products are cut from the continuously conveyed product strand. [0003] The cutting device essentially consists of a rotating knife holder with one or more cutting knives and a hose with guides for the product strands, wherein the hose is also formed simultaneously for the guides for the product strands. Support for cutting knives that move through the product strip. Du...
