Abstract: Recycling and reprocessing of waste plastic bottles is an important technical problem in environmental protection engineering. The cap and body are made of different materials. If they were not separated, they would pollute each other. Therefore, the separation of plastic bottle cap and label becomes an indispensable part of plastic bottle processing and recycling.A plastic bottle cap separator was designed, in which the bottle body clamping system did not need to be rotated, and feeding, clamping, screwing, cutting and recycling were completed in the same position in turn; the clamping mechanism was automatically centered, which was suitable for different sizes of bottle body, and could increase the success rate of screwing and the accuracy of cutting position; the tray was designed in the shape of a fan to complete the axial support, cutting and recycling of bottle body.

Key words: cap separator, automatic centering, clamping mechanism, separation by screwing the cap
