[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the lower slot plate and the upper slot plate, multiple jade discs can be limited at the same time, so that when the No. 1 servo motor drives the gear to roll on the tooth plate, thereby driving the hanger to move and propel, it can drive multiple jade discs to contact the No. 1 grinding head and the No. 2 grinding head for grinding, thereby increasing the number of single grindings and thus improving the grinding efficiency.

Under the staggered arrangement of the No. 1 grinding head and the No. 2 grinding head, when the No. 1 grinding head is grinding one side of the jade disc, the No. 2 limit plate will support the jade disc from the back, so that the jade disc can fully contact with the No. 1 grinding head for grinding. Similarly, when the No. 2 grinding head is grinding the other side of the jade disc, the No. 1 limit plate will support the jade disc from the front, so that the jade disc can fully contact with the No. 2 grinding head for grinding, avoiding the phenomenon of affecting grinding due to poor contact, thereby effectively ensuring the grinding quality.

[0014] 2. When the hanger moves forward, the guide wheel will roll along the end slope of the clamping guide rail to drive the clamping frame to move downward, and then drive the upper groove plate to move downward, clamping the jade disc between the upper groove plate and the lower groove plate automatically. The process does not require workers to clamp manually, which effectively improves the convenience of use.

[0015] 3. When the upper and lower groove plates on one side are used to clamp and grind the jade discs, another batch of jade discs can be placed on the lower groove plate on the other side. After the jade discs between the upper and lower groove plates on one side are polished, the jade discs on the other side can be directly pushed to the polishing area for polishing. This reciprocating process can save the time spent on taking and placing the jade discs and improve the polishing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
