hobboing cutters

10,10 ' do to toss about in bed mutually, and then the shape that will fragmentate by paper cutting therebetween.

Above-mentioned habitual cutter structure, the shape though paper cutting can be fragmentated, but its principle mainly utilizes interconnected set of blades 14 that paper is divided into strip, the paper of strip is blocked again become the fragment shape by the sword 18 that blocks that is convexly equipped with on set of blades 14 circumference again, therefore the paper sheet thickness that is cut is directly blocked the restriction of sword 18 height, and the fragment of gained still has suitable width, that is the recognition rate of fragment content is still quite high, causes preventing the effect and the ideal not as expecting of file content outflow.

Moreover, relatively poor because the direction that the point of a knife of set of blades 14 and paper are advanced is parallel to the towing effect that paper produces, in the process of actual operation if when meeting the fragment accumulation, promptly cause the phenomenon of paperboard easily.

Novel content

The purpose of this utility model is, improved at the blade structure that shredder is habitually practised, provide a kind of processing and manufacturing easily, shredded paper also can reduce cost than lightweight and effectively avoid taking place paperboard, and reduction fragment content is by the structure-improved of a kind of kneader bar of identification possibility.

Particularly, the utility model structure is as follows: a kind of structure-improved of kneader bar, and its blade hobboing cutter parallel by two groups and that lean on is constituted; It is characterized in that:

Two groups of hobboing cutters have the set of blades of several corresponding settings, and each set of blades is made of first blade and second a straight blade of a curved arc shape of mutual applying; This first blade, one end has one and can load the groove of rounded washers, has the paper guiding sheet that set of blades is separated between the set of blades of facing mutually, and the set of blades on two groups of hobboing cutters is combined together interlacedly.

In the practicality, whole blade cylindrical shape hobboing cutter parallel by two groups equally and that lean on is constituted, and in the two groups of actions that the cylindrical shape hobboing cutter is done to toss about in bed mutually of ordering of tending to act of motor, reaches the purpose of the paper cutting that will run over; Wherein, two groups of corresponding several set of blades that are provided with of hobboing cutter, each set of blades is made of first blade and straight second blade applying of a curved arc shape, and the circumference that makes each set of blades forms asymmetrical point of a knife, in view of the above, do when tossing about in bed mutually at two groups of hobboing cutters, the set of blades on two groups of hobboing cutters promptly will be blocked by its paper that runs in the mode that point of a knife fits, so the fragment of institute's severing is asymmetrical fine debris, its content will greatly be lowered by the possibility of identification.

Especially, when actual operation, wherein first blade is a side of curved arc shape, is not that the direction of advancing with paper is parallel, and can produces the towing effect to paper, effectively avoid taking place paper jam phenomenon; Even, the set of blades on each hobboing cutter can be disposed in the mode that point of a knife is arranged as helix, the point of a knife of avoiding all set of blades drops on same axis, the stress during with the dispersion paper cutting, the durability of increase blade, and the fault rate that reduces shredder.
