[0002] Jewelry can be broadly or narrowly defined. In a narrow sense, jewelry refers specifically to jade products. In a broad sense, jewelry should include ornaments, handicrafts, or other collectibles made of gold, silver, and natural materials that have a certain value. However, with the development of society and the economy, the concept of jewelry should be expanded to include gold, silver, and jewelry, in addition to natural and artificial gemstones. The industry that deals in these items is collectively called the jewelry industry. The scope of jewelry is much larger than the broad concept of gemstones. In a broad sense, gemstones refer to raw materials that are suitable for cutting or carving into jewelry or handicrafts. Jewelry requires polishing equipment to be polished during processing to make it into the desired shape.

[0003] Existing jewelry polishing equipment, in actual use, does not allow jewelry to be easily removed from under the polishing disc. Workers need to reach under the polishing disc to retrieve the jewelry, which is dangerous. Furthermore, it does not allow for easy storage and protection of the polished jewelry, making it prone to breakage. Summary of the Invention

[0034] Step 3: During polishing, the delivery pump is started to draw polishing liquid from the polishing liquid storage tank through the inlet pipe, deliver it to the storage tank through the delivery pipe, and spray it out through the nozzle to spray polishing liquid onto the jewelry, which is then polished in conjunction with the polishing disc.

[0035] Beneficial technical effects of the present invention:

[0036] 1. The jewelry surface polishing and grinding device and grinding method according to the present invention, by setting a rack and a gear to cooperate with each other, the second motor can drive the rotating rod to rotate, which in turn can drive the gear to rotate. When the gear rotates, it can drive the rack to move. When the rack moves, it can drive the moving seat to move, which in turn can drive the placement box to move, thereby moving the jewelry out from under the grinding disc. This makes it convenient for workers to pick up the materials without having to reach under the grinding disc to pick them up.

[0037] 2. By setting up a protective cover and a placement box to work together, the second motor can start to drive the rotating rod to rotate, which in turn drives the gear to rotate. When the gear rotates, it can drive the rack to move. When the rack moves, it can drive the moving seat to move, which in turn drives the placement box to move. When the placement box moves, it can move the main extrusion block away from the auxiliary extrusion block. At this time, the spring returns to its original position, which can drive the moving ring to slide on the moving rod, thereby closing the placement box, which can facilitate the protection of the processed jewelry.

The engagement of the mounting block 62 with the mounting groove facilitates the installation and disassembly of the placement box 6. The rack 41 and... The wheels 43 work together, and the second motor 53, when started, drives the rotating rod 51 to rotate, which in turn drives the gear 43 to rotate. When the gear 43 rotates, it drives the rack 41 to move, which in turn drives the moving seat 4 to move, which in turn drives the placement box 6 to move, thus removing the jewelry from under the polishing disc 26. This makes it easier for workers to retrieve the jewelry without having to reach under the polishing disc 26. By setting the moving ring 72 to slide and connect with the moving rod 61, it is easy to guide and limit the protective cover 7. By setting the connecting column 8, it is easy to support the main extrusion block 81. The base frame 83 facilitates support for the auxiliary extrusion block 82.
