A plastic waste shredding device

Abstract

The invention discloses a plastic waste crushing device. The plastic waste crushing device comprises a circular crushing barrel and a cutter rotary shaft. The top of the circular crushing barrel communicates with a feed pipe in a connected mode. The cutter rotary shaft is arranged in the circular crushing barrel. Two hinged shaft parts of the cutter rotary shaft are hinged to two end plates of the circular crushing barrel. The ends of the hinged shaft parts extend out of the two end plates of the circular crushing barrel and are hinged to supporting plates. The supporting plates are welded and fixed to a machine frame. A rotating driving motor is fixed to the machine frame. A driving gear is fixed to an output shaft of the rotating driving motor. The end of one hinged shaft part extends out of the corresponding supporting plate and is fixedly provided with a driven gear. The driving gear is engaged with the driven gear. An inlet and an outlet of the circular crushing barrel of the plastic waste crushing device are both located at the feed pipe. Plastic products can be crushed after being placed into the circular crushing barrel and after the feed pipe covers the circular crushing barrel automatically. During crushing, the crushed plastic products cannot flow out directly, so that the crushing effect is ensured.

Description

Technical field: [0001] The invention relates to the technical field of plastic processing equipment, and more specifically relates to a plastic waste crushing device. Background technique: [0002] Existing plastic products need to be crushed and stirred for recycling. The existing crushing device is generally equipped with an inlet at one end of the barrel and an outlet at the other end. After the plastic products are put into the inlet, they are crushed and cut by the cutter on the rotating shaft. From the outlet, it stays in the barrel for a short time, the crushing is not sufficient, and the effect is limited, and its cutter is generally formed with multiple annular protrusions on the rotating shaft, and the blades are fixed on the annular protrusions, and then used, because of its annular protrusions The quantity is large, and it is troublesome to fix the blades by bolts, which makes their replacement very troublesome. Invention content: [0003] The purpose of the ...
