It deeply interferes with the normal pipe grinding work. When the grinding block rotates in the inner cavity of the grinding shell, when passing through the cleaning rack, the outer surface of the grinding block is rotated and cleaned by the rotating rack, and the residue adhered to the grinding block and the pipe are polished. The generated iron filings are cleaned to prevent the iron filings from adhering to the surface of the cleaning block when the cleaning block is cleaning and polishing the surface of the grinding block, thereby causing the iron filings to get stuck between the grinding block and the cleaning block when cleaning the grinding block. This causes uneven extrusion on the surface of the grinding block, thereby interfering with the grinding work of the pipe end surface by the grinding block. When the cleaning block cleans and polishes the grinding block, the grinding block continues to rotate, causing the iron plate to pass through the connecting block on the connecting rod. It slides in the inner cavity, so that the waste generated after cleaning the grinding block is scraped off, and the waste is scraped into the inner cavity of the grinding shell.

3. The present invention sets a trimming mechanism and adjusts the rotating knob so that the ejector needle is fixed in the middle of the pipe to prevent vibration when grinding the pipe surface. When the outer surface of the grinding block is uneven, the outer surface of the grinding block needs to be trimmed. When the fixed pin is rotated, the fixed pin is separated from the fixed hole, thereby adjusting the height of the diamond pen to adjust according to the different thicknesses of the grinding wheel. At the same time, a brush is provided to sweep away the waste generated during dressing.

4. In the present invention, by setting up a collection mechanism, when the grinding block rotates in the inner cavity of the grinding shell, the waste chips and residual materials generated are cleaned by the cleaning mechanism, and then the waste materials fall in the inner cavity of the collection shell. The grinding block rotates, so that the grinding block rotates and the collection shell is rotated at the same time, so that the accumulated waste chips falling from the bottom of the inner cavity of the grinding shell rotate through the collection plate in the inner cavity of the collection shell, so that the collection plate will The waste chips are collected into the inner cavity of the collection shell. When the collection shell rotates, the collection spring is stretched by centrifugal force, causing the knocking block to knock on the inner wall of the polishing shell, thereby knocking the waste attached to the polishing shell. Shocked down to facilitate collection.
