Description

{A device for shredding plastic or PET bottles}

The present invention relates to a plastic or PET bottle shredder, and more particularly, to an improved plastic and PET bottle shredder so that the plastic or PET bottle inputted into the hopper can be well inserted and crushed between the shredding cutters.

In general, it is a known fact that waste plastics or waste PET bottles (hereinafter abbreviated as plastic or PET bottles) are shredded and recycled for recycling, and the device for shredding plastic or PET bottles as described above is a prior art document presented as a patent document in the prior art literature. It is common to use a shredding cutter like a technological plastic bottle shredder.

However, in a PET bottle shredder like the prior art, the PET bottle input to the hopper has a circular shape on the circumferential surface, so when the plastic bottle touches the edge of the shredding cutter, it is splashed outward, causing a problem that it cannot be crushed quickly. As the crushing efficiency decreases, the product reliability decreases.
