Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The present embodiment is related to a kind of grinding roller, as shown in Figure 1, mainly including four part-structures:
Shaft of grinding roller 1 is formed with boss 7 close to the middle part of the shaft of grinding roller 1 on the outer peripheral surface of shaft of grinding roller 1；
Grinding roller core 2 is sheathed on shaft of grinding roller 1 and is located at 7 side of boss, passes through key between grinding roller core 2 and shaft of grinding roller 1
Connection；Due in milling apparatus operational process grinding roller keep high speed rotation, in order to further increase grinding roller torsional property,
And then the abrasion of grinding roller is reduced, grinding roller core 2 can be connect with shaft of grinding roller 1 using spline, such grinding roller can bear biggish
Torque.Grinding roller in the prior art is mostly single tube structure, and crushing effect is general, and grinding roller core 2 in the present embodiment
Outer peripheral surface is tapered, and grinding roller core 2 and grinding roller sleeve 3 can be made to be fitted close, improve grinding effect.
In the present embodiment, it is also devised with groove 9 (as shown in Figure 2) in the outer peripheral surface of grinding roller core 2, groove 9 is uniformly distributed in
The outer peripheral surface of grinding roller core 2, groove 9 run through and are connected between the large end face and small end face of grinding roller core 2；Since milling apparatus is run
Process will cause grinding roller operating temperature and increase, easily the abrasion of aggravation grinding roller, therefore in order to further decrease the abrasion of grinding roller, this reality
It applies example and also designs the cross-sectional width of each groove 9 having a size of 1-2mm, depth dimensions 1-2mm, this structure will not make shaft of grinding roller 1
It deforms and influences grinding effect, and have certain good effect to grinding roller heat dissipation；The grinding roller angle of grinding roller core 2 is 13.5 °, this makes
The goodness of fit obtained between grinding roller and mill is more preferable, increases abrasive areas, and then improve grinding efficiency.
The another object of the present embodiment is reduction production cost, and to achieve the goals above, the present embodiment design includes
Grinding roller sleeve 3, is sheathed on the periphery of grinding roller core 2, and the outer peripheral surface and inner peripheral surface of grinding roller sleeve 3 are in cone；It is needed after grinding roller abrasion
When exchanging, grinding roller sleeve can be directly replaced, grinding roller core 2 continues to use, and it is easy to operate, while reducing production cost；
First baffle 4 and second baffle 5, are sheathed on shaft of grinding roller 1, and are located at the two of grinding roller core 2 and grinding roller sleeve 3
End, is equipped with two ring through hole 8 of arrangement annular in shape on first baffle 4 and second baffle 5, can refer to as shown in Figure 3 the
The structure of the structure of one baffle 4, second baffle 5 is similar with the structure of first baffle 4, and only size is less than first baffle 4, favorably
It radiates in grinding roller, further decreases grinding roller abrasion.Meanwhile the two gap positions between ring through hole 8 is corresponding to each groove 9
Position, it is ensured that grinding material will not sputter milling apparatus by circular hole 8；First baffle 4 and second baffle 5 are by aluminum
Material is made, and the heat dissipation effect of grinding roller is further increased using the thermal conduction characteristic of metal；And then reduce abrasion.
Nut 6 is spirally connected with shaft of grinding roller 1 in the other end of grinding roller core 2 and is connected relative to boss 7.Grinding roller core 2 in order to prevent
The loosening that is spirally connected with shaft of grinding roller 1 will affect grinding, and the quantity of nut 6 can be two.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
