Polishing equipment for bottle opening of PET (Polyethylene Terephthalate) bottle

Abstract

According to the PET bottle opening polishing equipment, in the working process of the PET bottle opening polishing equipment, the pulling plate is pulled, so that the pulling plate drives the extrusion plate to abut against the inner wall of the bearing cylinder through the sliding column. A to-be-polished PET bottle is placed in the bearing cylinder, the pulling plate is loosened, the extension spring recovers elastic deformation, and the pulling plate and the sliding column drive the extrusion plate to extrude and fix the to-be-polished PET bottle. The driving air cylinder drives the to-be-polished PET bottle to move close to the polishing table through the driving plate and the bearing cylinder. And a bottle opening of the PET bottle to be polished is inserted into the annular polishing groove and abuts against the arc-shaped polishing grooves of the two polishing rings. And the driving motor drives the grinding table to rotate through the rotating plate, so that the two grinding rings grind the edge of the bottle opening of the PET bottle to be ground. In the process, the dust collector adsorbs dust generated in the polishing process through the dust collection pipe, the annular dust collection cavity, the dust collection holes, the annular dust collection channel and the annular polishing groove.
