This utility model discloses a
pelletizing device for recycling waste plastic bottles, including a
machine body, a feeding hopper, and a crushing roller. A pair of first partitions and a pair of second partitions are respectively arranged from top to bottom between the feeding hopper and the crushing roller. These first and second partitions are horizontally opened or closed by a power structure. A pair of
extrusion plates are installed between the first and second partitions via a telescopic component. A collection hopper is located below the crushing roller, and collection boxes one and two are located below the collection hopper. In this utility model, the plastic bottles in the feeding hopper are retained in the
extrusion space formed by the first and second partitions before falling onto the crushing roller. The
extrusion plates press and deform the bottles, changing their shape. When the deformed bottles contact the crushing roller, the problem of tumbling and slipping is effectively reduced, which helps improve the crushing efficiency. Furthermore, the extrusion process does not affect the normal feeding of the plastic bottles into the feeding hopper.
