Specific embodiment
Further details of non-limitative illustration is made to the utility model with reference to the accompanying drawings and examples.
Embodiment one
As shown in Figure 1, the magnetic roll of embodiment one includes roll body 1 and several magnetic posts for being set on 1 roll surface of roll body
Nail 2 and several bar magnets 3, magnetic stud 2 are arranged with the interval of bar magnet 3.It is preferable that magnetic stud 2 is arranged with bar magnet 3 in roller
On the entire roll surface of body 1, and it is along the axial direction of roll body 1 and circumferentially uniformly distributed.
As shown in Fig. 2, 1 structure of roll body of roll magnetic in Fig. 1 is made comparisons with the roller structure of the prior art, line of demarcation
It is the roller structure of the prior art on the left of L, is provided only with stud mounting hole 11 on roll surface.It is the present embodiment on the right side of the L of line of demarcation
Magnetic roll roller structure, what is be spaced on the roll surface of roll body 1 is provided with several stud mounting holes 11, the magnetism stud
2 are installed in stud mounting hole 11, and magnetic stud 2 is higher than the roll surface of roll body 1；In roll surface without stud region, the setting at interval
There are several bar magnet mounting holes 12, the bar magnet 3 is installed in bar magnet mounting hole 12, and bar magnet 3 is concordant with roll surface or is higher than roll surface.
Wherein, magnetic stud 2 can be installed on stud mounting hole 11 by way of being bonded or being interference fitted, and equally, bar magnet 3 can also be with
Bar magnet mounting hole 12 is installed on by way of being bonded or being interference fitted.
As depicted in figs. 1 and 2, wherein the aperture of stud mounting hole 11, depth are respectively greater than the hole of bar magnet mounting hole 12
Diameter, depth；The diameter of magnetic stud 2, height are respectively greater than the diameter of bar magnet 3, height.
As shown in Figure 1, wherein magnetic stud 2 can be designed as monolithic construction, i.e., each magnetic stud 2 is single zero
The magnetic stud of part, monolithic construction is made of magnetic hard alloy.Magnetic stud 2 uses monolithic construction, facilitates system
It makes and installs, but cost is slightly higher.
