This invention discloses a two-stage stepped
crusher for waste plastics, including a frame, a crushing section and a shearing section mounted on the frame; a guide member is provided inside the frame, with the feed end of the guide member connecting to the
discharge end of the crushing section and the
discharge end of the guide member connecting to the feed end of the shearing section; a conveying mechanism is provided inside the guide member, and the conveying mechanism includes a conveying component located at the feed end of the shearing section, with a guide strip at one end of the conveying component for diverting materials; the guide strip fixed to one end of the conveying component divides the guide plate into multiple sets of groove structures, and the separated grooves facilitate the orientation of plastic objects to the conveying component; and a
combing component movably connected inside the guide strip achieves
reciprocating motion through a drive unit, causing the
combing component to change the direction of long strips of plastic objects placed horizontally on the guide strip. This device achieves a combination of conveying, guiding and
combing, which not only ensures the smooth feeding and conveying efficiency of various
plastic materials, but also avoids the horizontal accumulation of long strips of plastic objects and prevents blockage.
