The utility model relates to the technical field of
metal nail surface
machining, in particular to a
metal nail production
polishing device which comprises a device supporting frame, a
polishing barrel is rotationally installed on the device supporting frame, a sealing
barrel plate is installed on the
polishing barrel in a hinged mode, a discharging filter plate is arranged below the polishing barrel, and a supporting frame is fixedly installed at the lower end of the discharging filter plate. According to the
metal nail production polishing device, the
metal nail production polishing device is designed to be used for screening
abrasive materials and discharged metal nails, after the metal nails are polished, the metal nails can be separated from the supporting frame, the metal nails can be separated from the supporting frame, and therefore the metal nails can be separated from the supporting frame, and the yield of the metal nails can be improved. The metal nails are taken out of the polishing barrel, the metal nails and
grinding materials are screened through the discharging filter plate, the
grinding materials are collected through the collecting tank, the
grinding materials are lifted and conveyed back into the polishing barrel through the lifting mechanism, the polishing work of the second batch of metal nails is facilitated, and therefore the working efficiency is effectively improved.
