Description
Technical field
The utility model relates to a kind of pulverizer, especially relates to a kind of in order to pulverize the plastics that reclaim, the efficient rotary pawl cutter of the plastic crusher that crush efficiency is higher.
Background technology
At present, the pawl cutter of known molding powder pulverizer generally has two classes.One class pawl cutter two ends respectively are provided with a blade, and the center is provided with axis through-hole, and axis through-hole is provided with a keyway.But such design exists not enough.Pawl cutter one end only for being provided with a blade, during the work of pawl cutter, can't cut by the blade back, and crush efficiency is lower; The keyway that axis through-hole is provided with is one only, is contained in the rotating shaft loosening easily.Another kind of pawl cutter two ends all are provided with a plurality of blades, and upper and lower plates face edge is equipped with cutting edge, but this kind design has caused new problem again.This class pawl cutter is to be made by one flat plate integral body mostly, by groove being set in dull and stereotyped side, form two-layer corresponding up and down blade, the blade branch is located at the edge of upper and lower plates face, during this type of pawl cutter work, the plastics fritter falls into easily in groove, and effect is cut in influence, and offers when shallow when cell body, cut weak effect, when cell body was offered deeply, easy rust of blade and bending, service life is shorter.
Summary of the invention
The utility model mainly is that solution existing in prior technology crush efficiency is lower, and the pawl cutter is contained in the loosening easily technical problem that waits in the rotating shaft, provides a kind of efficient that cuts higher, and the pawl cutter is contained in the difficult efficient rotary pawl cutter that becomes flexible in the rotating shaft.
It is shorter service life that the utility model also solves existing in prior technology pawl cutter simultaneously, and manufacture craft is the technical problem of complexity etc. comparatively, provides a kind of service life longer, the comparatively simple efficient rotary pawl cutter of manufacture craft.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: efficient rotary pawl cutter, comprise cutter hub and the axis through-hole with keyway provided thereon, the cutter hub two ends are arranged with the swallow-tail form edge, and cutter hub is provided with a plurality of blades perpendicular to the edge of the end face of central axis, it is characterized in that: described swallow-tail form edge is provided with the curved blade that axial symmetry is provided with; Be provided with the pointed shape cutter hub that axial symmetry is provided with between the edge, middle part of cutter hub and the curved blade, described curved blade is on two different aspects with the pointed shape cutter hub, and the thickness of described pointed shape cutter hub can be 1/3～2/3 of cutter hub thickness.Curved blade is located on two different aspects with pointed shape cutter hub branch and a plurality of settings is arranged, and has increased the blade number of pawl cutter, has improved crush efficiency; Curved blade and pointed shape cutter hub are the individual layer setting in the cutter hub side, have solved the depression problem of plastics fritters, and it is better to interrupt effect, and service life is also longer.
As preferably, it is one dull and stereotyped whole that described cutter hub can be.For easily manufactured, reduce cutter hub manufacturing process, as preferably, described cutter hub also can form for being combined between the higher and lower levels by two flat boards.
As preferably, the thickness of described pointed shape cutter hub is about half of cutter hub thickness.Symmetrically arranged pointed shape cutter hub, when the pawl cutter rotated, the knife back also can cut, and helped the pulverizing of plastics, had improved crush efficiency.
As preferably, described curved blade is the arc flat board of uniform thickness, and identical substantially with the thickness of pointed shape cutter hub.The not flexible and rust of curved blade increases the service life.
Make for convenience, as preferably, the bottom surface of the end face of described curved blade and pointed shape cutter hub is separately positioned on the upper and lower plates face of cutter hub.
As preferably, described axis through-hole is provided with the keyway more than 1 or 1.The number of keyway should be set according to the structure of rotating shaft in the reality, the setting of a plurality of uniform keyways, it is more firm to make that the pawl cutter is contained on the rotating shaft.
Therefore, the utlity model has following characteristics: 1. simple in structure, be provided with rationally; 2. divide to be located at two-layer a plurality of blades, improved and cut effect, it is higher to cut efficient; 3. structure of the cutter body is simple, and is easily manufactured, low cost of manufacture; 4. the uniform thickness setting of cutting edge and blade has prolonged service life; 5. the setting of many keyways, pawl cutter are contained on the rotating shaft comparatively firm.
