Description

GERMAN

With a rotating knife carrier, cutting machines with powered circular knives for vegetable matter, especially tobacco, are known.

It is also known to continuously increase the distance between the material to be cut and the cutting knife edge change. So far, this has happened in accordance with the knife wear, in particular through regrinding by axial longitudinal displacement of the knife carrier. In such cutting machines, one is proportionate Complicated design required to feed the ground knives.

The invention thus relates to an infeed of cutting machines, especially for tobacco on a rotating knife holder overall ¹ S superposed driven circular knives, with the distance between the end face of the mouthpiece for the material to be cut and the knife cutting edge is continuously variable.

The invention consists in that the mouthpiece is parallel to the knife carrier axis and continuously in Direction of the passed circular knife is displaceable.

This design enables the simplest possible delivery between circular knives and the material to be cut causes. A simple, cheap and easily manufactured type of such cutting machines is created, since now the knife carrier himself can remain in his position.

The main advantage of the invention is that between the housing and knife carrier This embodiment of the delivery device does not change the distance, which in particular the drive and the correct holding in position the circular knife cutting edge and the abrasive is structurally solved in a simple manner.

The object of the invention is illustrated in the drawing in one embodiment, namely The figure shows a cutting machine with a stationary, rotatable knife carrier.

The cutting machine is provided with a mouthpiece 10, through which the material to be cut 11 in a known Way, for example with conveyor belts 12, rollers or the like. Is promoted. To cut the Material to be cut serve in particular plate-shaped circular knives 13, for example four pieces that are attached to one rotating knife carrier 14 are mounted. By rotating the knife carrier, the circular knives 13 : passed in the mouthpiece 10.

Each circular knife is either driven by a single motor or the circular knife Infeed device on cutting machines for vegetable substances, in particular tobacco

driven jointly by the shaft 15 of the knife carrier. The knife carrier shaft 15 is driven for example from the motor 16 and the transmission gear 17.

The distance between the material to be cut and the cutting knife edge is regulated during regrinding the cutting knife continuously in that the mouthpiece 10 with an immovable knife carrier for Knife carrier axis 15 is displaceable in parallel. The mouthpiece is slidable, for example, by a Sleeve 18 is formed which engages with a flange 19 in a displaceable carriage and is continuous by means of a drive 21, for example a spindle gear, in the direction of the passed at the mouthpiece Circular knife 13 is moved.

The drive of the threaded spindle 21 takes place, for example, by means of a worm gear 22 from a Motor not shown, which at the same time drives the conveyor belts 12.

Claims (1)

PATENT CLAIM: Infeed device on cutting machines for vegetable substances, in particular tobacco, with a rotating knife carrier mounted, driven circular knives, whereby the distance between the end face of the mouthpiece for the material to be cut and the cutting knife edge continuously is variable, characterized in that the mouthpiece (10) is parallel to the knife carrier axis and is continuously displaceable in the direction of the circular knives (13) that have been moved past.
