The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The lapping device that becomes more meticulous of a kind of neodymium iron boron powder as shown in Figure 1 to Figure 3, comprise grinding chamber 1, and be located at the grinding ring 2 in grinding chamber 1, and be located at the motor shaft 3 at grinding chamber 1 center, and be located at the mixing roll 4 on motor shaft 3, described mixing roll 4 and grinding ring 2 coordinate formation to grind gap 5, the cross section of described mixing roll 4 is inverted trapezoidal, madial wall on described grinding ring 2 is provided with plup inlet, on the lateral wall of described grinding ring 2, connect feed pipe 6, described feed pipe 6 tops connect feeding warehouse 7, described motor shaft 3 is driven by the motor 8 of being located at grinding chamber 1 bottom, on described motor shaft 3, be also provided with lowering or hoisting gear, described grinding chamber 1 top is provided with discharging opening 9, on described motor shaft 3, be positioned at mixing roll 4 belows and be provided with perching knife 10.
Described lowering or hoisting gear comprise the driving cylinder 11 be located on grinding chamber 1 bottom and with the vertical drive rod being connected 12 of described motor shaft 3, thereby described driving cylinder 11 connects drive rod 12 drive motor axle 3 liftings.
Described grinding chamber 1 lateral wall is provided with controller 14, and described controller 14 comprises display screen 14-1, operating key 14-2 and PLC plate 14-3, and described PLC plate 14-3 controls motor and drives cylinder 11 work.
Described feeding warehouse 7 bottoms are provided with vibrator 15.
Between described feeding warehouse 7 and feed pipe 6, be provided with check valve 16.
During work, neodymium iron boron raw material enters from feed pipe, closing one-way valve, mixing roll work starts to grind, and grind qualified material and send from discharging opening, but along with the carrying out of grinding, discharging speed slows down, and therefore by lowering or hoisting gear, reduces to grind gap, further improves grinding efficiency.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
