Abstract

This utility model discloses a label removal machine for waste PET bottles. An electric heating element is installed at the front of the interlayer between the inner and outer cylinders of the label removal cylinder, and an air inlet is opened at the rear. The label removal roller is rotatably mounted inside the label removal cylinder, and its surface is axially arranged with multiple sets of circumferentially distributed alloy scrapers. The electric heating element locally heats the front of the label removal cylinder, effectively softening the adhesive layer of the PET bottle label and reducing the difficulty of label removal. The axially distributed alloy scraper sets create a multi-stage scraping action when the label removal roller rotates, significantly improving label removal efficiency while reducing mechanical damage to the bottle. The air separation system utilizes the negative pressure airflow generated by a centrifugal fan to efficiently suck up and separate the peeled labels through the air inlet, achieving rapid classification of labels and bottles and improving overall recycling efficiency.
