Description
[technical field]
The present invention relates to a kind of lapping device, particularly about a kind of lapping device in order to material is disperseed.
[background technology]
Lapping device is widely used in numerous areas, and its function is the graininess that the cake mass of large volume is ground into small size, and perhaps originally granular material grinds to form littler Powdered of particle diameter.Because to the demand difference of the particle size that obtains material, to the also corresponding difference of performance demands of lapping device.
A kind of lapping device of prior art as shown in Figure 1, its effect mainly is that pigment evenly is dispensed in coating or the printing ink.This lapping device 10 comprises roller 11, sand cylinder 12, first rotating shaft 131, second rotating shaft 132 and motor 14.This sand cylinder 12 is used to hold pigment to be ground (figure does not show).This first rotating shaft 131 is parallel to each other with second rotating shaft 132 and is positioned on the different axis, and this first rotating shaft 131 and second rotating shaft 132 are connected as one by connecting rod 133.When motor 14 drove these first rotating shaft, 131 rotations, this second rotating shaft 132 can be done in a big way rotation around this first rotating shaft 131.This roller 11 is placed in second rotating shaft 132, when this second rotating shaft 132 is rotated, this roller 11 also rotates thereupon, in addition, because there are certain clearance in this roller 11 and sand cylinder 12 inwalls, when being contained with pigment in the sand cylinder 12, roller 11 is owing to produce friction by pigment and sand cylinder 12 inwalls, and this roller 11 also will rotate around second rotating shaft 132.
In process of lapping, the roller 11 of this lapping device 10 is the inwall rollings along sand cylinder 12, and this roller 11 produces squeezing action with sand cylinder 12 inwalls to the pigment that is sandwiched in therebetween, and this squeezing action produces shearing force again pigment is disperseed.But the efficient that this lapping device 10 grinds with roll mode merely is lower, for pigment grind is disperseed, needs long milling time usually.And, since the gap length between this roller 11 and sand cylinder 12 inwalls directly influence the particle size of the pigment after grinding, and this lapping device 10 is in process of lapping, and this gap length is constant, and this kind lapping device 10 is difficult to grind the particle diameters of pigment littler than this gap.
[summary of the invention]
Below, will a kind of lapping device with higher grinding efficiency be described with embodiment.
For realizing foregoing, a kind of lapping device is provided, it comprises sand cylinder, motor, first rotating shaft, second rotating shaft, roller, AC power and two piezoelectric ceramic pieces.This first rotating shaft links to each other with second rotating shaft, and this motor drives this first rotating shaft and rotates.This roller is set in this second rotating shaft and is positioned at this sand cylinder, and this second rotating shaft and roller roll along the sand cylinder inwall under the drive of first rotating shaft.This two piezoelectric ceramic piece is separately fixed at the both sides of one section metal part in this first rotating shaft, and this AC power, two piezoelectric ceramic pieces and this section metal part constitute vibrator.
Compared with prior art, because the lapping device of present embodiment has vibrator, this vibrator can cause first rotating shaft to do the swing of disalignment, this swing further passes to the roller in second rotating shaft, this roller can be when the sand cylinder inwall rolls, also vibrate with respect to this sand cylinder inwall, the impact that this vibration produces will speed up material dispersed to be ground, thereby improves grinding efficiency.In addition, the grinding mill apparatus of this kind oscillatory type can also grind the particle diameter of material to be ground littler.
