Description

A kind of shredder

Technical field

The utility model relates to a kind of shredders, specifically, be it is a kind of the smashed collapsed portion of paper can be separated, And the fragment being partially separated is crushed into the shredder for paper pulp again.

Background technique

Shredder is that a kind of common office privacy device for crushing file prevents file from divulging a secret.Shredder is most Using blade shaft shred file, although can by file text and figure be chopped into paper slip or small pieces, broken paper slip It is deposited in the paper shredding barrel of shredder with small pieces in certain rule, making file still has biggish a possibility that being reduced.In addition There are also one kind to soak processing shredder, and file is broken into paper pulp rather than the scraps of paper by way of adding water infiltration to crush again, make by Smashed paper loses the external form of paper, can restore unlike the scraps of paper, to more effectively protect confidential information. But it is more huge compared with common shredding machine to soak processing shredding machine, needs biggish installation space, and general small office, The interior space of shop or family is limited, is unfavorable for soaking the placement of processing shredder.

Utility model content

The utility model aim be intended to provide it is a kind of the smashed collapsed portion of paper can be separated, and will part point From fragment crush the shredder for paper pulp again.

To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:

A kind of shredder including two cutter axis being driven by motor in upper casing, upper casing, and is connected to below upper casing Paper shredding barrel is provided in the upper casing fragment that smashed fragment is partially separated separating export agency again, described broken It includes conveying box and screw conveyor shaft that piece separates export agency again, and the both ends of the screw conveyor shaft are rotatably connected on by bearing The two sides of conveying box, the screw conveyor shaft are connected by the motor of gear assembly and cutter axis；The shape of the conveying box with The shape of screw conveyor shaft matches；The lower section of shredded paper mouth of the conveying box between two cutter axis, and conveying box One end is fixed on the side of upper casing, the other side of the other end through upper casing and the outside positioned at upper casing；The top of the conveying box It is provided with paper feed port, the top of the screw conveyor shaft protrudes from the outside of conveying box, the paper feed port position by the paper feed port In in upper casing；The lower part of the conveying box is provided with exit slot, and the exit slot is located at outside upper casing；The helical feed axial screw The thickness of blade is greater than the width of gap between screw, and fragment falls after the cutter axis crushes paper, and fraction fragment passes through spiral Gap is dropped into conveying box, and rest part fragment is fallen into paper shredding barrel due to blocking for helical blade；Under the exit slot Side is provided with water tank, fragment feed inlet corresponding with exit slot is provided at the top of the water tank, and fragment feed inlet is located at paper delivery The underface of mouth, the fragment fallen into conveying box is delivered to exit slot by screw conveyor shaft, and enters water by fragment feed inlet In case；The water tank is internally provided with fragment disintegrating mechanism again, and by fragment, disintegrating mechanism will discharge into the shredded paper powder of water tank again Broken is paper pulp.

It further limits, the water tank is divided into infiltration case and crush box, the level for crushing box cavity by partition Section is rounded, and the height for crushing box cavity is less than the height of infiltration box cavity；The fragment feed inlet is located at infiltration case Top；The upper and lower part of the partition is provided with the through-hole for being connected to infiltration case with crush box, has dress in infiltration case and crush box There is water, and fills water in crush box；Disintegrating mechanism includes the shredded paper axis in crushing box cavity to the fragment again again, described broken The upper end of paper axis is rotatably connected on the roof center position of crush box by bearing, and shredded paper axis passes through gear assembly and spiral transferring Send axis connection；The bottom end radial equipartition of the shredded paper axis has at least two pieces of guide vanes, and the rotation of guide vane can make crush box In water flow up, circulate water between infiltration case and crush box by upper and lower two through-holes of partition, and drive Fragment into water tank circulates between infiltration case and crush box with water；It is provided with above the guide vane broken Paper knife and shredded paper disk, the paper shredding blade and shredded paper disk are in the form of annular discs, and disc size is slightly less than the big of crush box cross section It is small；The paper shredding blade is fixed on shredded paper axis, and the bottom surface of paper shredding blade is provided with the roll flute for grinding shredded paper, paper shredding blade with it is broken Paper axis center line is identical；The shredded paper disk is rotatably connected on shredded paper axis, and the pivot center of the shredded paper disk is the axis of shredded paper axis Line, and shredded paper disk is located at the lower section of paper shredding blade, has between the top surface of the shredded paper disk and the bottom surface of paper shredding blade broken for grinding The gap of paper；The aperture passed through for shredded paper is provided on the shredded paper disk, the quantity of the aperture is four, and shape is sector.

The utility model due to above-mentioned design advantageously: separate export agency again by fragment to cutter axis Smashed fragment is separated again, enters fraction fragment in conveying box by the gap between screw of screw conveyor shaft, Remaining partial piece avoids all fragments from all concentrating on being easier to restore at one since the blocking of helical blade enters in paper shredding barrel, And because the rotation of screw conveyor shaft, the position moment of gap between screw are changing, it is provided with the fragment entered in conveying box Certain randomness is less useful for the reduction of fragment；Discharging into water tank in conveying box will be entered later, by infiltration case to fragment Carrying out infiltration makes fragment be easier to be crushed, and recycles the guide vane of shredded paper axis lower end that fragment is made to enter crush box, and pass through Aperture on shredded paper disk makes fragment enter shredded paper disk and paper shredding blade to be ground into paper pulp by between, fragment is made to lose the form of paper And lose the possibility being reduced；The confidentiality of shredder is greatly improved for paper pulp by the way that fraction fragment is crushed, and The volume of shredder can't substantially be increased by carrying out infiltration crushing to fraction fragment, be conducive to make equipment in various places With.
