Description
Technical field
The invention belongs to reducing mechanism technical fields, and in particular to a kind of roll shaft grinder and its mating cutter head.
Background technology
Roll shaft grinder cutter head is mostly manner connection in the prior art, detachable when breaking down, but connection mode
Mostly bolt fastens, and acts acutely, easily shakes off bolt, the bolt and cutter head to come off can touch in the roll shaft grinder course of work
It hits on other cutter heads, even if operating personnel keep 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.
Invention content
The purpose of the present invention is to provide a kind of roll shaft grinder and its mating cutter heads, easy to solve cutter head in crushing process
The problem of coming off, influencing production.
In order to solve problem above, technical solution of the present invention is：
A kind of roll shaft grinder, including interior roll shaft, outer roll shaft, outer roll shaft is located at outside interior roll shaft, and the two of interior roll shaft and outer roll shaft
End is plugged in together respectively by interior pin, and at least three rows of openings are axially arranged on outer roll shaft, cutter head, knife are equipped in each trepanning
Head upper end is pierced by trepanning outer surface.
Further, trepanning is often arranged at least provided with three, and each trepanning is distributed on outer roll shaft.
Further, trepanning 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 interconnected 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.
Beneficial effects of the present invention are as follows：Roll shaft grinder is divided into interior roll shaft and outer roll shaft by the present invention, and cutter head is from outer roller
The trepanning of axis is pierced by, and is inserted into outer roll shaft to fix cutter head by interior roll shaft, is fixed between interior outer roller with external pin, even if working
Strenuous vibration in the process, the fixation of entire cutter head is safe and reliable, will not loosen, and prevents cutter head caused by being fixed and loosened due to cutter head
Come off the other cutter heads of collision, greatly prolongs the service life of cutter head, increases the maintenance cycle of roll shaft grinder；Trepanning is distributed on outer
On roll shaft, ensure to crush the uniformity；The design of trepanning cross sectional shape ensures that under the action of interior roller bearing cutter head is stuck in out well
Kong Zhong；External pin further ensures that interior pin will not be come off due to vibrations in work, facilitate observation to adjust；Interior roll shaft diameter
It is equal with outer roll shaft internal diameter, ensure the integration linkage of roll shaft grinder in crushing process.
Cutter head is divided into two parts, only the usage amount of cutter head high strength steel is greatlyd save with outer cutter head is replaced when replacing cutter head,
Save cost；Outer cutter head lower part is equipped with annular magnet, on the one hand ensures that cutter head absorption position on outer roll shaft is relatively solid during installation
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.
Structure novel of the present invention, operation maintenance are convenient, avoid " head of forging a knife " phenomenon in crushing, substantially increase work
Efficiency.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention 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 is 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 are plugged on one by interior pin 3 respectively
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 trepanning 4 often drains into few
If there are three, each trepanning 4 is distributed on outer roll shaft 2, and trepanning 4 is trapezoidal along the section of outer 2 radial direction of roll shaft, in each trepanning 4
Equipped with cutter head 5,5 upper end of cutter head is pierced by 4 outer surface of trepanning, and cutter head 5 is cone, and cutter head 5 is adapted with 4 shape of trepanning, 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 and outer cutter head 52 being combined into one to form cutter head 5, outer cutter head 52 uses high strength steel,
Ensure crushing effect, the interior common iron of cutter head 51, inside and outside cutter head mutually plugs, and absorption is one under the action of annular magnet 6
It rises, cutter head 5 is inserted into the trepanning 4 of outer roll shaft 2, adsorbed in trepanning 4 under the action of annular magnet 6, when ensureing to install to the end
Do not fall, interior roll shaft 1 be inserted into outer roll shaft 2 after installing, with interior pin 3 fix in roll shaft 1 and outer roll shaft 2, then with outside
Pin 3 in the fixation of pin 7 ensures that interior pin will not be come off due to vibrations in work, facilitate observation to adjust.
During operation, roll shaft grinder is started, material is crushed, in crushing process, the fixed safety of entire cutter head 5 can
It leans on, will not loosen, prevent the cutter head caused by the loosening of 5 fixing device of cutter head from coming off and collide other cutter heads, greatly prolong knife
First 5 service life increases the maintenance cycle of roll shaft grinder.
