Brief description of the drawings
Fig. 1 is the structure principle chart according to permanent magnetic pulley of the present invention.
Detailed description of the invention
As shown in Figure 1, be respectively equipped with suitable, left-hand thread according to the outer surface of the both sides, middle part of the rotating shaft 1 of hollow permanent magnetic pulley 12 of the present invention, to match with suitable, the left-hand thread of the inner surface along adjustment barrel 5 and counter regulation cylinder 18 respectively.This is all provided with the first hinge 141 along adjustment barrel 5 and counter regulation cylinder 18 lateral surfaces.
Be offset to the rotating shaft 1 of permanent magnetic pulley 12, at the inner surface place of the hollow permanent magnetic pulley 12 of distance, be provided with pole plate 15.A side of facing rotating shaft 1 at pole plate 15 is all provided with the second hinge 142.One end of connecting rod 13 is hinged by pin and the first hinge 141, and other one end of connecting rod 13 is hinged by pin and the second hinge 142.Be fastened in rotating shaft 1 by screw 4 respectively along adjustment barrel 5 and counter regulation cylinder 18.
The two ends of connecting rod 13 are all hinges, and lower hinge is an element that hinge axis hole is provided being fixed on pole plate, and connecting rod 13 and lower hinge form the structure of similar hinge like this, can swing.Magnet 16 is fixed on pole plate 15, between pole plate 15 and the inner surface of hollow permanent magnetic pulley 12.
Like this, the rotating shaft 1 of hollow permanent magnetic pulley 12, just formed a linkage along adjustment barrel 5, counter regulation cylinder 18, connecting rod 13, pole plate 15.
Along between adjustment barrel 5 and roller end cover 11, be all provided with sliding bearing 6 between counter regulation cylinder 18 and roller end cover 11.Roller end cover 11 use screws 10 are installed together with cylinder 12.Roller end cover 11 is arranged in frame 9 by bearing 8 and fixed cap 19.Belt pulley 7 is installed on roller end cover 11.
Bearing 6 must, with sliding bearing, because both needed to rotate along adjustment barrel 5 and counter regulation cylinder 18, also need, with bearing 6, relative moving axially occurs.
The wherein side of rotating shaft 1 (for example left side) is provided with a step, and position-limited rack 3 is inserted in the outside of this step, and position-limited rack 3 is fixed on roller end cover 11, in the outside of position-limited rack 3, retainer ring 2 is installed, and retainer ring 2 is fastened in rotating shaft 1.The side position-limited rack 3 that this step is arranged on belt pulley 7 can and then rotate, and is arranged on and does not have a side of belt pulley 7 (can be fixed on fixed cap 19) position-limited rack 3 can and then not rotate.On counter regulation cylinder 18, opened one along the longitudinal keyway of rotating shaft 1, fixed cap 19 outsides are provided with the screw 17 that can stretch into this keyway." keyway " can only design is not having a side of belt pulley 7, static because screw 17 (being fixed on fixed cap 19) needs, and belt pulley 7 one sides can be rotated.
In the time need to adjusting the Surface field of cylinder 12, first screw out marking closely screw 4, rotating shaft 1 can independently be rotated, meanwhile, screw 17 be screwed in the keyway of counter regulation cylinder 18 but do not mark closely, utilizing screw 17 as feather key, like this, with regard to can only being moved axially, counter regulation cylinder 18 can not rotate.
Because counter regulation cylinder 18 and suitable adjustment barrel 5, pole plate 15, connecting rod 13, rotating shaft 1 have formed linkage, so, equally also can only move axially and can not rotate along adjustment barrel 5.
In the time of this rotating shaft 1 of rotation, because rotating shaft 1 can not move axially and can only rotate under the effect of position-limited rack 3 and retainer ring 2, and what process respectively along adjustment barrel 5 and counter regulation cylinder 18 endoporus is suitable, left-hand thread, having ensured that like this rotation centerline in two adjustment barrels 5,18 is constant, the distance between two adjustment barrels 5,18 will shorten or elongate.
Due to the movement of two adjustment barrels 5,18, connecting rod 13 is swung, thereby makes pole plate 15 rise or decline, magnet 16 away from or near cylindrical shell, thereby adjust the Surface field intensity of cylinder 12.
After determining the Surface field intensity of cylinder 12, then will mark closely screw 4 and mark closely, and make to form an entirety along adjustment barrel 5, counter regulation cylinder 18 and rotating shaft 1; And will mark closely screw 17 and unclamp, and depart from the keyway of counter regulation cylinder 18, like this, after rotating shaft 1 rotates to certain angle with moving magnet 16, then screw 17 will be tightened in the keyway of counter regulation cylinder 18, and make magnet 16 be fixed on certain angle.
For example, can adopt the rotation of belt drives belt pulley 7, belt pulley 7 drives roller end cover 11 and cylinder 12 to rotate by key, material falls above cylinder 12, under the guiding of rotating at cylinder 12 along cylinder 12 surfaces to whereabouts, material can an absorption part continue rotation on cylinder 12 surfaces after touching magnetic field, and rest materials continues to whereabouts; The material that is attracted to cylinder 12 surfaces continues to rotate to the position that there is no magnetic field, and this part material can drop, thereby realizes the separation of material.
