The handles, cup mouths and cup bottoms of melamine resin water cups cast by the mold are often provided with burrs which affect the appearance and use, and secondary processing procedures such as deburring are generally required. The traditional method for removing the burrs of the melamine resin product is to manually polish, firstly coarsely grind by using a grinding wheel, then finely grind by using a hemp wheel, and finally polish by using a cloth wheel. Although the manual polishing method can achieve the expected effect of removing burrs, the manual polishing method is time-consuming, labor-consuming, long in production period and high in labor cost, and polishing work cannot be finished in time or polishing effect cannot be guaranteed under the condition of mass production; in addition, the manual hand-held grinder polishes melamine resin products, and the high-speed rotating grinding wheel is easy to hurt arms and causes work injury, so that polishing noise is high, dust is diffused, and the influence on human hearing and respiratory systems is caused. Therefore, if the automatic equipment capable of automatically removing burrs of melamine resin water cups, tableware and other similar products can be invented, the production efficiency of melamine resin tea sets and tableware can be greatly improved, and the production cost can be reduced.

The bin separation positioning mechanism places the product 50 (melamine resin water cup) to be polished on the clamping die 21, and the jacking mechanism jacks the bottom of the melamine resin water cup tightly, so that the clamping work of the product is completed. The rotation driving device drives the melamine resin water cup to rotate by a certain angle, so that the cup handle of the melamine resin water cup rotates to a horizontal direction. Then, the slide base 23 is driven to move forward by the front-rear driving mechanism 24, so that the product 50 to be ground is moved to be close to the milling cutter 11. Under the driving of the milling lifting driving mechanism 14 and the milling left-right driving mechanism 15, the sliding bottom plate 23 is driven to move back and forth by being matched with the front-back driving mechanism 24, and the milling cutter 11 finishes milling and polishing on the surface of the product 50. For example: to polish the cup handle burrs of the melamine resin cup, under the driving action of the milling lifting driving mechanism 14 and the milling left-right driving mechanism 15, the sliding bottom plate 23 is driven by the front-rear driving mechanism 24 to drive the product to be processed to move forwards and backwards, and the side cutting edge of the milling cutter 11 contacts the surface of the cup handle and mills and polishes the surface of the cup handle according to a preset track, so that the polishing work of the cup handle burrs of the melamine resin cup is completed.
If the melamine resin water cup has two left and right cup handles which are required to be polished, after the burrs of the cup handle on one side are polished, the rotation driving device drives the melamine resin water cup to rotate 180 degrees, and the polishing work is repeated on the other cup handle. If burrs are required to be polished on the cup mouth and the cup bottom of the melamine resin cup, the rotary driving motor 26 is started to drive the melamine resin cup to rotate around the axial direction, and the milling cutter 11 contacts the burrs on the cup mouth or the cup bottom and completes polishing work on the burrs on the cup mouth and the cup bottom of the melamine resin cup respectively by virtue of cutting rotation of the milling cutter and cutting displacement generated by the axial rotation of the melamine resin cup relative to the milling cutter 11.
After finishing the polishing work of melamine resin cup deckle edges, the front and rear driving mechanism 24 drives the sliding bottom plate 23 to drive the product 50 to withdraw backwards. The rotatable jack module 28 of the jack mechanism retracts under the action of the jack cylinder 27, releasing the clamping of the product 50. The ejection cylinder 62 drives the ejection rod 61 arranged in the axial hollow of the output rotating shaft 22 and the clamping bearing die 21 to push out, so that the melamine resin cup and the clamping bearing die 21 are loosened, and preparation is made for blanking.
