Description

Technical Field

[0001] The utility model relates to the technical field of porcelain bottom surface processing, in particular to a polishing device used for fine finishing of porcelain bottom surfaces. Background Art

[0002] Porcelain is made of porcelain stone, kaolin, quartz stone and mullite, and is covered with glassy glaze or painted on the surface. Porcelain is formed by high-temperature firing in a kiln. The glaze color on the surface of porcelain will undergo various chemical changes due to different temperatures. It is a treasure displayed by Chinese civilization.

[0003] Polishing the bottom of porcelain can ensure the flatness of the bottom of porcelain and improve its aesthetics. However, the existing porcelain bottom polishing device places the porcelain on top of the polishing equipment for polishing. The stability of the porcelain is poor and it is easy to shake during the polishing process, resulting in poor polishing effect. Therefore, we propose a polishing device for fine finishing of the bottom surface of porcelain. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a polishing device for fine finishing of the bottom surface of porcelain, which has the following beneficial effects:

[0016] 1. The polishing device for fine finishing of the bottom surface of porcelain is implemented by clamping the porcelain upside down in the inner cavity of the arc-shaped clamping groove, and the suction cup is in contact with the top wall of the inner cavity of the porcelain, and then starting the micro air pump. At this time, the input end of the micro air pump evacuates the air in the inner cavity of the connecting tube, the inner cavity of the U-shaped cavity and the inner cavity of the hollow tube, and discharges it through the inner cavity of the exhaust pipe. At the same time, negative pressure is generated in the air evacuation path. At this time, the suction cup vacuum absorbs and fixes the porcelain, so as to facilitate the fixation of the porcelain and has strong stability, thereby avoiding the phenomenon that the porcelain shakes during the polishing process and causes poor polishing effect.

[0017] 2. The polishing device for fine finishing of the bottom surface of porcelain starts the electric push rod and shortens it. At this time, the electric push rod drives the carrier plate to move and moves toward the bottom surface of the porcelain until the polishing disc is moved to a position where the bottom surface of the porcelain can be polished. Then the drive motor is started. At this time, the output shaft of the drive motor drives the polishing disc to rotate, and the polishing disc polishes the bottom surface of the porcelain, thereby facilitating the polishing of the bottom surface of the porcelain.
