Definitions
- the invention relates to a document shredder for use in offices.
- the material to be shredded with the aid of this document shredder is generally a paper sheet stack of coated or normal paper or environmental paper.
- the material to be shredded in the form of plastic films, such as those used on overhead projectors, or in the form of computer disks and so-called compact discs, briefly referred to as "CD", or digital versatile discs, called “DVD” for short are examples of plastic films, such as those used on overhead projectors, or in the form of computer disks and so-called compact discs, briefly referred to as "CD", or digital versatile discs, called “DVD" for short ,
- This arrangement of the suction end of the suction device also has the advantage that no coarse particles of the material to be comminuted are also extracted. These Coarse particles fall namely only below the cutting unit and fall due to their own weight in a corresponding, arranged below the cutting unit in a conventional manner collecting container. A suction of these coarse particles would have the disadvantage that they could clog the filter element, so that either the suctioned air from the suction device could no longer escape from the suction device and thus the housing of the document shredder or the coarse particles could be deposited on the filter element with the result that the filtering effect of the filter element is affected in relation to the particulate matter.
- the functionality of the cutter of a document shredder is only guaranteed if the cutting rollers are lubricated at regular intervals with a suitable oil. Otherwise it exists Risk that the cutting rollers become clogged with coarse particles from the shredded material and clog it up.
- the lubrication has the task to reduce the friction in the intermeshing cutting rollers.
- regular periodic relubrication of the cutting unit in the case of document shredders is usually forgotten by the operator, despite the fact that the oil can is supplied. Clogging the cutting unit with cutting particles can lead to long-term failure of the cutting unit and thus failure of the entire document shredder.
- the mode of operation of the document shredder according to the invention is as follows: Through the introduction chute 8 the material to be shredded is introduced in the insertion direction 26 into the document shredder.
- the good to be crushed happens here first the tactile finger 15 of the detector 6. If the detector 6 releases the material to be comminuted for comminution, run the drive motor 4 and thus cutting unit 3 and at the same time the suction fan 10 of the suction device 5 at.
- the lubricated by the lubricating device 7 cutting unit 3 crushes the material to be shredded. This creates heat at the cutting unit 3.
- the rising from the cutting unit 3 against the insertion 26 in the feed channel 2 warm air contains particulate matter.
