Paper shredder handling device of document shredder using roller {omitted}

The present invention relates to an apparatus for processing a paper shredded in a document shredder, and more specifically, to modify the shape of the paper scraps by using a roller (Roller) that is interlocked with the paper shredded in the document shredder to the outside state, The present invention relates to a shredded gripping apparatus of a document shredder using a roller which is dewatered and made into a certain paper mass.

In general, national agencies, government offices, corporations and financial institutions dealing with documents that require security maintenance are shredded and shredded using document shredders for security maintenance.

Therefore, when the document is shredded using the document shredder, the volume of the shredding phage increases and is stacked in the bin located at the bottom of the shredding cart. Therefore, the tip of the shredded phage is detected by the sensor. Whenever the operation of the cutting screw stops and stops, the user has to open the cover of the main body and disperse the stacked thin papers of the collection box and use it again.

In addition, the shredded paper retains the shape of the paper pieces having a certain size, and when discarding these pieces of paper, the shredded paper is stored in the plastic bag when the waste paper is dumped in a plastic bag. Therefore, in the case of a confidential document which is likely to be recovered by another person and requires personal information and security, there is a problem in that a part of the document is leaked.

Water is used to easily transform and crush the shape of the shredded pieces of paper. In the case of document shredders installed and used in offices, the amount of documents to be shredded is usually small, and the work of destroying the documents is not continuous. Therefore, in processing the shredded phage, the overload occurs when the grinder is restarted when water is naturally evaporated from the pulped shredder remaining in the grinder to change into a hard paper mass. Due to this, there is a problem that it is difficult to miniaturize the shredded gripping processing apparatus that must be installed in a limited space of the document shredder because the power unit for driving the mixed grinding device is required a large capacity.

The present invention has been devised to solve the above problems, by deforming the form of the paper pieces so that it is impossible to recover by using a roller that rotates by engaging the pieces of paper shredded by the cutting cutter of the document shredder, dehydration, constant shape It is an object of the present invention to provide a shredded gripping apparatus of a paper shredder using a roller for making paper mass.

Deforming the shape of the paper piece absorbing water, which is the core function of the present invention, into an unrecoverable state, as shown in Figures 4a and 4b, it can be implemented by grinding the embossing effect on the paper pieces.

Therefore, when any projection 41 of the uneven forming roller 4a presses any surface of the piece of paper, the circumferential curved surface of the urethane 31 of the pressing support roller supporting the piece of paper and the projection enters the length of the projection. One side of the paper piece 101 located between the projection surface is also entered into the embossing (embossing) effect on the paper piece, resulting in an arbitrary side of the paper piece is extended to change the shape of the paper piece.

The circumferential surface of urethane is formed because the circumferential speed of the uneven forming roller 4b is greater than the circumferential speed of the pressing support roller while the projection of the uneven forming roller 4b is in contact with the circumferential surface of the urethane 31 of the pressing support roller. The paper pieces may be finely cut by the shear friction force generated in the paper pieces 101 sandwiched between the protrusions and the protrusions, thereby changing the shape of the paper pieces.

In addition, the dehydration roller (5) is dehydration as the main function, but when the urethane of the pressure support roller is engaged with the urethane state is greater than the circumferential speed of the pressure support roller, the circumferential curved surface and the piece of paper in which the plurality of dehydration holes (52) The friction between the paper fragments are worn out due to the friction between the secondary can be obtained the effect of changing the shape of the paper fragments.
