Description

Technical Field

[0001] The utility model relates to the field of plastic furniture manufacturing, in particular to a burr grinding device for plastic furniture. Background Art

[0002] There is usually an opening on the top of a plastic stool for taking things. The upper surface of the opening is relatively smooth, but there will be burrs inside. People will feel their hands cut or even injured when using it, which is very inconvenient to take things. Therefore, the inside of the opening of the plastic stool needs to be polished during the processing. The current polishing method is relatively simple, and it is difficult to polish stools of different sizes, and the scope of application is narrow. Although manual polishing can be performed according to different stools, the grinding stability is not enough, which may cause the flash edge to be not polished flat enough. Utility Model Content
