Description

Bottle neck ring removing device for high-purity PET bottle flake production Technical Field The invention relates to the technical field of PET bottle flake production, in particular to a bottle neck ring removing device for producing high-purity PET bottle flakes. Background The bottleneck ring of the PET bottle generally refers to a disposable fracture anti-theft ring. It is a safety design for ensuring that the bottled product is not opened. When the consumer unscrews the bottle cap, the anti-theft ring can be separated and remained on the bottle due to the action of heat or external force, so that a method for identifying whether the bottled product is unsealed is provided. The disposable fracture anti-theft ring (lower bottle neck ring) and the bottle cap are integrally injection molded by adopting the same material, when the plastic bottle cap is additionally arranged on the bottle mouth of the PET bottle, the bottle neck ring and the bottle cap are connected in a multi-point mode through a mechanical segmentation mode, when the bottle cap is opened, under the action of the bottle mouth limiting ring, the bottle cap is matched with the upward spiral tension force of the bottle cap, so that the joint is broken, and one bottle neck ring is mostly left at the bottle mouth position. In the production process of PET bottle flakes, the bottle caps and the label tapes are removed, and the bottle neck rings are removed in the same process, so that the purity of the PET bottle flakes is ensured. The existing bottle neck ring removing method is few in manual treatment, the time spent on manual treatment is relatively long, the bottle neck ring is partially cut at multiple angles in a cutting mode, so that the bottle neck ring is separated from a PET bottle, the PET bottle is easily cut in the cutting mode, PET scraps are mixed into bottle neck ring waste, and the PET scraps are not easy to separate. The melting point of the PET bottle is between two hundred and fifty degrees centigrade and between two hundred and fifty degrees centigrade, the bottleneck ring is usually made of polyethylene or polypropylene, the melting point of the polyethylene is between one hundred and fifteen degrees centigrade, the melting point of the polypropylene is between one hundred and sixty degrees centigrade and between one hundred and seventy degrees centigrade, and the melting temperature of the polyethylene and the polypropylene is far less than that of the PET bottle, so that the melting and cutting modes are adopted, and the PET bottle is relatively simpler and more convenient.
