Description
Technical field
The utility model belongs to grinding device technical field, and in particular to a kind of roll shaft grinder and its mating cutter head.
Background technique
Roll shaft grinder cutter head is mostly manner connection in the prior art, detachable when breaking down, but connection type
Mostly bolt fastening, movement acutely, is easy to shake off on bolt, the bolt and cutter head to fall off can touch in the roll shaft grinder course of work
It hits on other cutter heads, even if operator keeps close, is shut down in time when hearing abnormal sound of movement, when maintenance can all find cutter head
The phenomenon that being chased or being damaged, since mating cutter head hardness is big, cost is high, and production cost is also very high, and the periodic inspection frequency is high,
Midway, which will also shut down, when encountering relatively tight duration, continuous production overhauls the production that is switched on again, largely effects on working efficiency.
Utility model content
The purpose of this utility model is to provide a kind of roll shaft grinder and its mating cutter heads, to solve knife in crushing process
It is easy to fall off, the problem of influencing production.
In order to solve problem above, technical solutions of the utility model are as follows:
A kind of roll shaft grinder, including interior roll shaft, outer roll shaft, outer roll shaft are located at outside interior roll shaft, interior roll shaft and outer roll shaft
Both ends pass through interior pin respectively and be plugged in together, at least three rows of openings are axially arranged on outer roll shaft, are equipped with knife in each aperture
Head, cutter head upper end are pierced by aperture outer surface.
Further, at least provided with three, each aperture is evenly arranged on outer roll shaft the every row of aperture.
Further, aperture is trapezoidal along the section of outer roller axis radial direction.
Further, the both ends of interior pin are respectively equipped with external pin.
Further, interior roll shaft diameter is equal with outer roll shaft internal diameter.
Further, cutter head is cone, and cutter head is adapted with hole shape, cutter head include the interior cutter head that interconnects with
Outer cutter head, outer cutter head lower part are equipped with annular magnet.
Further, outer bit tip is spininess or zigzag.
Further, interior cutter head and outer cutter head mutually plug.
Further, outer cutter head material is high strength steel.
The beneficial effects of the utility model are as follows: roll shaft grinder is divided into interior roll shaft and outer roll shaft, knife by the utility model
Head is pierced by from the aperture of outer roll shaft, is inserted into outer roll shaft by interior roll shaft to fix cutter head, is fixed between interior outer roller with external pin, i.e.,
Make strenuous vibration during the work time, the fixation of entire cutter head is safe and reliable, will not loosen, and prevents from loosening since cutter head is fixed and draw
The cutter head risen, which falls off, collides other cutter heads, greatly prolongs the service life of cutter head, increases the maintenance cycle of roll shaft grinder；Aperture
It is evenly arranged on outer roll shaft, guarantees to crush the uniformity；The design of aperture cross sectional shape guarantees that under the action of interior roller bearing, cutter head is fine
Be stuck in aperture；External pin further guarantees that interior pin will not be fallen off due to vibration in work, facilitate observation to adjust；It is interior
Roll shaft diameter is equal with outer roll shaft internal diameter, guarantees the integration linkage of roll shaft grinder in crushing process.
Cutter head is divided into two parts, only greatlys save the usage amount of cutter head high strength steel with outer cutter head is replaced when replacing cutter head,
Save cost；Outer cutter head lower part be equipped with annular magnet, on the one hand guarantee installation when cutter head be adsorbed on outer roll shaft it is upper set it is relatively solid
It is fixed, facilitate roll shaft in insertion；On the other hand magnetize outer cutter head, irony object is adsorbed in crushing process；Outer bit tip is spine
Shape or zigzag, work in coordination, and crushing effect is more preferable.
The utility model structure novel, operation maintenance are convenient, avoid " head of forging a knife " phenomenon in crushing, substantially increase
Working efficiency.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figs. 1-5, a kind of roll shaft grinder, including interior roll shaft 1, outer roll shaft 2, outer roll shaft 2 are located at outside interior roll shaft 1
Portion, interior 1 diameter of roll shaft is equal with outer 2 internal diameter of roll shaft, and the both ends of interior roll shaft 1 and outer roll shaft 2 pass through interior pin 3 respectively and are plugged on one
It rises, the both ends of interior pin 3 are respectively equipped with external pin 7, and at least three rows of openings 4 are axially arranged on outer roll shaft 2, and aperture 4 often drains into few
If there are three, each aperture 4 is evenly arranged on outer roll shaft 2, aperture 4 along the radial section of outer roll shaft 2 be it is trapezoidal, in each aperture 4
Equipped with cutter head 5,5 upper end of cutter head is pierced by 4 outer surface of aperture, and cutter head 5 is cone, and cutter head 5 is adapted with 4 shape of aperture, cutter head 5
Interior cutter head 51 and outer cutter head 52 including interconnection, interior cutter head 51 and outer cutter head 52 mutually plug, and outer 52 top of cutter head is point
Thorn-like or zigzag, outer 52 lower part of cutter head are equipped with annular magnet 6, and outer 52 material of cutter head is high strength steel.
Before operation, interior cutter head 51 being combined into one to form cutter head 5 with outer cutter head 52, outer cutter head 52 uses high strength steel,
Guarantee that crushing effect, the interior common iron of cutter head 51, inside and outside cutter head mutually plug, is adsorbed on one under the action of annular magnet 6
It rises, cutter head 5 is inserted into the aperture 4 of outer roll shaft 2, adsorbed in aperture 4 under the action of annular magnet 6, when guaranteeing to install to the end
It does not fall, interior roll shaft 1 is inserted into outer roll shaft 2 after the installation is completed, fix interior roll shaft 1 and outer roll shaft 2 with interior pin 3, then outside
