Abstract

This utility model relates to the field of polyethylene pipe production technology, specifically a waste recycling device in polyethylene pipe production. It includes a crushing box with a drive shaft and a driven shaft rotatably mounted inside. Crushing rollers are fixedly sleeved on both the drive and driven shafts. A motor is installed on the side wall of the crushing box. During the crushing process, this utility model can efficiently separate small waste particles that meet the required particle size from larger, incompletely crushed waste particles. The small waste particles that meet the required size can be directly processed for subsequent cleaning, heating, and plasticizing. The larger, incompletely crushed waste particles are then fed back into the crushing box for repeated crushing. This ensures that the polyethylene waste meets the required particle size before subsequent processing, preventing incompletely crushed waste from affecting subsequent cleaning, heating, and plasticizing processes.
