DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a polishing apparatus, and more particularly to a polishing apparatus for dispersing materials. [Prior Art] The polishing apparatus is widely used in many fields, and its function is to pulverize a bulky mass of material into a small volume of particles, or to grind a substantially granular substance into a powder having a smaller particle size. Due to the different requirements on the particle size of the obtained material, the requirements for the performance of the grinding device are also different. A prior art grinding device, as shown in the first figure, mainly functions to uniformly disperse the pigment into the paint or ink. The polishing apparatus 10 includes a roller U, a polishing cylinder 12, a first rotating shaft 131, a second rotating shaft 132, and a motor 14. The grinding cylinder 12 is for holding a pigment to be ground (not shown). The first rotating shaft 131 and the second rotating shaft 132 are parallel to each other and on different axes, and the first rotating shaft 131 and the second rotating shaft 132 are integrally connected by a link 133. When the motor 14 drives the first rotating shaft 131 to rotate, the second rotating shaft 132 can perform a wide range of rotation around the first rotating shaft 131. The roller 11 is sleeved on the second rotating shaft 132. When the second rotating shaft 132 rotates, the roller 11 also rotates. In addition, since the roller u and the inner wall of the grinding cylinder 12 have a certain gap, when grinding When the pigment is contained in the cylinder 12, the roller u generates φ friction by the pigment and the inner wall of the grinding cylinder 12, and the roller 11 will also rotate around the second rotating shaft 132. During the grinding process, the roller u of the grinding device 10 rolls along the inner wall of the grinding cylinder 12, and the roller 11 and the inner wall of the grinding cylinder 12 squeezing the pigment sandwiched therebetween, and the pressing action produces shear The shear force disperses the pigment. However, the polishing apparatus 10 is low in efficiency by simply rolling, and it is usually required to have a long polishing time in order to grind and disperse the pigment. Moreover, since the size of the gap between the roller 11 and the inner wall of the polishing cylinder 12 directly affects the particle size of the ground pigment, and the grinding device 1 is in the grinding process, the gap size is constant, and the grinding is constant. It is difficult for the device 10 to grind the particle size of the pigment to be smaller than the gap. SUMMARY OF THE INVENTION Hereinafter, a polishing apparatus having a high polishing efficiency will be described by way of examples. In order to achieve the above, a grinding apparatus is provided, which comprises a grinding cylinder, a motor, a first turn 5 1322710 shaft, a second rotating shaft, a roller, an alternating current power source and two piezoelectric ceramic sheets, the first rotating shaft being connected to the second rotating shaft' The motor drives the first rotating shaft to rotate, the roller is sleeved on the second rotating shaft and located in the grinding cylinder, and the second roller and the roller are rolled along the grinding wall by the first rotating (four), The two piezoelectric ceramics are respectively disposed on both sides of the first-turning-section metal portion, and the alternating current power source, the two piezoelectric ceramic sheets and the metal portion of the segment constitute a vibrator. Compared with the prior art, the polishing apparatus of the present embodiment has a vibrator which can cause the first rotating shaft to swing away from the axial center, and the swing is further transmitted to the roller on the second rotating shaft, the roller It is possible to vibrate relative to the inner wall of the grinding cylinder while rolling along the inner wall of the grinding cylinder, and the impact force generated by the vibration will accelerate the dispersion of the material to be ground, thereby improving the grinding efficiency. + φ In addition, the vibrating grinding device can grind the particle size of the material to be ground to a smaller extent. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Referring to the second drawing, the polishing apparatus 3 of the present invention includes a roller 31, a polishing cylinder 32, a first rotating shaft 331, a second rotating shaft 332, a motor 34, and two piezoelectric ceramic sheets 35, 36. The grinding cylinder 32 is used to hold the pigment to be ground. The first rotating shaft 331 and the second rotating shaft 332 are parallel to each other and on different axes, and the first rotating shaft 331 and the second rotating shaft 332 are integrally connected by a connecting rod 333. The roller 31 is rotatably sleeved on the second The rotating shaft 332 is disposed, and the roller 31 and the second rotating shaft 332 extend into the grinding cylinder 32. The roller 31 is preferably disposed at the bottom of the grinding cylinder 32. The motor 34 is fixed to an external member and is coupled to the first rotating shaft ® 331, to drive the first rotating shaft 331 to rotate. Of course, the grinding cylinder 32 also needs to be fixedly disposed with respect to the motor 34. Referring to the third and fourth figures, the two piezoelectric ceramic sheets 35, 36 are disposed on the first rotating shaft 331, and are passed through an AC power source 37, a wire 35, a wire 361, and a piezoelectric ceramic plate 35. A portion of the first rotating shaft 331 between 36 and 36 forms a vibrator. In the vibrator, the first rotating shaft 331 sandwiched between the piezoelectric ceramic sheets 35, 36 is made of a metal material. The specific structure of the vibrator includes: The first transfer 33 of the cylindrical gold scrap material, the two semi-cylindrical ceramic ceramic pieces 35 and 36', and the alternating current power supply 37 ^ the piezoelectric ceramic sheets 35 and 36 are opposite to each other in the polarization direction That is, the first rotating shaft 331 is symmetrical. The first rotating shaft 331 is fixedly coupled to the semi-cylindrical piezoelectric ceramic sheets 35 and 36, respectively. The first rotating shaft 331 is further disposed on the piezoelectric ceramic sheets 35 and 36. The electrical ceramic sheet 55 is electrically connected to the piezoelectric ceramic sheet 56 through a wire 553. The piezoelectric ceramic sheet 56 passes through the wire 563 and the conductive material. The ring 564 is electrically connected. The two ends of the AC power source 58 are elastically contacted with the conductive ring 564 and the first rotating shaft 531 through the conductive contacts 581 and 582 respectively. Since the first rotating shaft 531 is made of a metal material, one end of the AC power source 58 is equivalent to an electrical connection. The first rotating shaft 531 is sandwiched between the piezoelectric ceramic sheets 55 and 56. Thus, current can be supplied to the piezoelectric ceramic sheets 55 and 56' without hindering the movement of the first rotating shaft 531 and the piezoelectric ceramic sheets 55 and 56 thereon. Since the vibrator of the above-described structure has the same polarization direction of the piezoelectric ceramic sheets 55 and 56, it can be called an asymmetrical vibrator. The grinding apparatus using the asymmetric vibrator can also generate a vibration effect and improve the grinding of each crucible. rate. The polishing apparatus of the present invention may further have other embodiments, for example: using a lightly movable AC power supply, in which case the above-mentioned circuit structure that can be realized by means of the conductive ring and the conductive contact strip can be omitted, thereby satisfying the above circuit. Based on the cooperation relationship, the AC power source is configured to be rotatable together with the first rotating shaft. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
