Abstract
The invention discloses a machine core of a shredder. The machine core comprises a paper guide device and a shredding hob mechanism, wherein the shredding hob mechanism comprises two hob shafts and hobs arranged on the hob shafts, the paper guide device comprises two paper guide groups which is composed of a plurality of paper guides provided with protrusion parts, the hobs are integrally provided with section cutting blades which are matched with the paper guides opposite to the section cutting blades to cut paper into sections. The machine core of the shredder is characterized in that the section cutting blades have two mutually separated and symmetrically distributed tool noses, and a V-shaped groove is formed between the two tool noses. When the section cutting blade is opposite to the protrusion part, the protrusion part extends into the V-shaped groove, and therefore the invention is advantageous in that the V-shaped grooves of the section cutting blades are added with supporting points when the tool noses of the section cutting blades shear the paper after the hobs longitudinally cut the paper, so that the paper cannot move backwards and are forced to cut. When a plurality of paper is crushed, paper-cutting can be with less effort, and meanwhile all the paper can be ensured to cut, thereby increasing cutting rate of the paper.
Description
Technical field
The present invention relates to a kind of shredder, especially relate to a kind of movement of shredder.
Background technology
The movement of shredder is the core component of shredder, the movement of existing shredder comprise the core body that is provided with paper feed port and exit slot and paper feed port is set and exit slot between the hobboing cutter paper shredder, a kind of electric shredder is disclosed such as No. 200420071230.9 Chinese utility model patents that on December 21st, 2005, bulletin was authorized, comprise body and paper box, body contains shell and thread hob paper shredder.No. 200610052985.8 Chinese invention patents that on July 9th, 2008, bulletin was authorized in addition disclose a kind of movement of shredder, comprise the core body that is provided with paper feed port and exit slot, be provided with the hobboing cutter paper shredder between paper feed port and the exit slot, the hobboing cutter paper shredder comprises two cutter shafts that are provided with hobboing cutter.Be disposed with spaced a plurality of hobboing cutter on each cutter shaft, the interlaced arrangement of hobboing cutter on two cutter shafts.About core body comprises two symmetries lead the paper parts, lead the paper parts by the plastics integrated injection molding, lead the paper parts and comprise successively spaced lateral paper guide, the segment blade on every hobboing cutter and the lateral paper guide on its opposite cooperatively interact, and the paper of putting into is cut off.The operation principle of shredder is as follows: with the phase blade paper is vertically cut first, under the effect of lateral paper guide upper process section, blade on the cutter shaft (segment blade) thrusts by the paper slip after vertically cutting, thereby with the paper slip transversely cutting, finally is cut into and has the broken end of strip paper.Present blade is a sharp-pointed section, and the jut on itself and the lateral paper guide cooperatively interacts, and paper slip is cut off, but when paper to be pulverized is many, because load is larger, can cause paper to retreat and the phenomenon generation that can't cut off.
Summary of the invention
Technical problem to be solved by this invention provides a kind of movement of the effective shredder of cutting a sheet of paper.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of movement of shredder, comprise paper guide and hobboing cutter paper shredder, described hobboing cutter paper shredder comprises two cutter shafts and the hobboing cutter that is arranged on the cutter shaft, described paper guide comprises two lateral paper guide groups, be wholely set the segment blade on the described hobboing cutter, described each lateral paper guide group is comprised of a plurality of lateral paper guides, be provided with jut on the described lateral paper guide, the jut of the lateral paper guide on described segment blade and its opposite cooperatively interacts the paper segment, it is characterized in that described segment blade has is separated from each other and two symmetrical points of a knife, form the V-type groove between described two points of a knife, when the segment blade was relative with jut, described jut stretched in the described V-type groove.
Described hobboing cutter comprises two hobboing cutter monomers bonded to each other, and described point of a knife is separately positioned on the described hobboing cutter monomer.
Described jut stretch into the V-type depth of groove 1/2～4/5 between.
Described jut stretches into 2/3 place of V-type depth of groove.
Compared with prior art, advantage of the present invention is after relative hobboing cutter vertically cuts paper, when the point of a knife of segment blade thrusts paper, the much middle strong point of the V-type groove of segment blade, paper can't be retreated and paper is cut off by force, when pulverizing plurality of sheets of paper and open, it is more laborsaving to cut a sheet of paper, simultaneously can guarantee that all paper can both be cut off, promote the segment rate of paper.

The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
A kind of movement of shredder, comprise paper guide and hobboing cutter paper shredder, the hobboing cutter paper shredder comprises two cutter shafts 1 and the hobboing cutter 2 that is arranged on the cutter shaft, paper guide comprises two lateral paper guide groups, be wholely set segment blade 21 on the hobboing cutter 2, each lateral paper guide group is comprised of a plurality of lateral paper guides 3, be provided with jut 31 on the lateral paper guide 3, segment blade 21 cooperatively interacts the paper segment with the jut 31 of the lateral paper guide 3 on its opposite, segment blade 21 has and is separated from each other and two symmetrical points of a knife 211, form V-type groove 4 between two points of a knife 211, when segment blade 21 and jut 31 were relative, jut 31 stretched in the V-type groove 4.Hobboing cutter 2 comprises two hobboing cutter monomers 22 bonded to each other, and point of a knife 211 is separately positioned on the hobboing cutter monomer 22, and jut 31 stretches into 1/2 or 2/3 or 4/5 place of V-type groove 4 degree of depth.
