Abstract

A paper disintegrating mechanism of crumbled-type paper disintegrator includes two knife shafts arranged in the knife seat in parallel and rotating corresponding to each other and a plurality of blades serially fixed on the knife shaft; each two adjacent blades are adhered to each other to form a group; the surrounding of the blade is provided with at least one sharp serrated edge protruding outward; the device is characterized in that the protruding top part of the edge is provided with the inverted V-shaped protruding tine part. The corresponding place of the knife seat and the inverted V-shaped protruding tine part of the blade is better provided with the V-shaped groove; thus the paper can be further forced to be punctured, pulled to be cut off. Compared with the prior art, the utility model punctures and then cuts off the paper through the inverted V-shaped protruding tine part on the tine-gear blade on the crumbled-type paper disintegrator; the cutting efficiency is higher than the direct cutting of the V-shaped knife groove in the prior art; the matching of the V-shaped groove in the corresponding place of the knife seat can further improve the cutting efficiency and reduce the phenomenon of clamping paper.

Description

A kind of paper shredder of particle type shredder

Technical field

The utility model relates to a kind of shredder parts, particularly a kind of paper shredder of particle type kneader bar.

Background technology

Existing shredder, no matter be electronic or manual, be broadly divided into two classes: a class is the fringe type, promptly utilize its blade for shredding paper that waste paper is cut to elongate strip, usually, the roughly rounded or bowl-type of blade for shredding paper, in groups string solid two be arranged in parallel and relatively turnable cutter shaft on, when cutter shaft rotates, be cut to thin paper slip through the paper between the set of blades under the extruding of blade: another kind of is the particle type, promptly utilize its blade for shredding paper that waste paper is cut to the particle shape, its blade for shredding paper has been set up the sharp tooth blade of evagination at periphery on the basis of fringe type blade, make paper when being cut to thin paper slip, be cut off by this blade again, usually, when mounted, with the solid blade for shredding paper on cutter shaft of string per two be one group by sticking together, as the patent No. is kneader bar disclosing in the Chinese utility model patent " the hobboing cutter group of crushing type shredder " of 95216030.7 (publication number is CN2225897Y), and in this patent, in order to strengthen cutting off effect, its sharp tooth blade top also has V-shape sword groove.But nonetheless, it is good not enough to cut off effect, when particularly running into paper and making moist, causes paperboard easily.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of paper shredder that cuts off the higher particle type kneader bar of efficient at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the paper shredder of particle type shredder is included in two cutter shafts that be arranged in parallel, relatively turnable and the solid a plurality of blades on cutter shaft of going here and there in the tool rest, per two adjacent knife blades become one group together by pasting in the described blade, and have the sharp tooth blade of an evagination at least at periphery, it is characterized in that described convex cutting edge top has the convex tip of inverted V-shape.

Described tool rest is good in the corresponding position with the convex inverted V-shape tip of described blade to be provided with the V-shape groove, punctures, pulls and cut off with can further making being forced to property of paper like this; When described tool rest was involuted by following tool rest and upper cutter head, described V-shape groove can be arranged on the upper cutter head.

Compared with prior art, the utility model punctures cut-out then by the convex inverted V-shape tip of sharp tooth blade on the blade for shredding paper earlier with paper, it is higher by the mode that V-shape sword groove directly cuts off than prior art that it cuts off efficient, and by and the V-shape groove of tool rest corresponding position between cooperatively interact, also can further improve cut-out efficient, reduce the generation of paper jam phenomenon.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 5, be an embodiment of the present utility model, it is included in tool rest 1 interior two cutter shafts 2 that be arranged in parallel, relatively turnable and the solid a plurality of blades 3 on cutter shaft 2 of string, per two adjacent knife blades become one group together by pasting in the described blade 3, and also have two sharp tooth blades 31 that are 180 ° of evaginations that are oppositely arranged at periphery, the convex tip 31a that also has inverted V-shape at these evagination blade 31 tops, referring to Fig. 5:

Described tool rest 1 is involuted by upper cutter head 11 and following tool rest 12, referring to Fig. 2; Described upper cutter head 11 is provided with V-shape groove 11a in the corresponding position with the convex inverted V-shape tip 31a of described blade, referring to Fig. 3, Fig. 4.

Claims

1, a kind of paper shredder of particle type shredder, be included in two cutter shafts that be arranged in parallel, relatively turnable and the solid a plurality of blades on cutter shaft of going here and there in the tool rest, per two adjacent knife blades become one group together by pasting in the described blade, and have the sharp tooth blade of an evagination at least at periphery, it is characterized in that described convex cutting edge top has the convex tip of inverted V-shape.

2, the paper shredder of particle type shredder according to claim 1 is characterized in that described tool rest is provided with the V-shape groove in the corresponding position with the convex inverted V-shape tip of described blade.

3, the paper shredder of particle type shredder according to claim 1 and 2 is characterized in that described tool rest is involuted by following tool rest and upper cutter head, and described V-shape groove is arranged on the upper cutter head.
