This invention relates to the technical field of plastic recycling, and more particularly to a centralized processing device for polyethylene waste, comprising side plates, a first connecting plate, a first hydraulic telescopic cylinder, a second connecting plate, limiting rods, an extrusion assembly, and a drive assembly; several side plates are connected to a support block; a first connecting plate is disposed above the support block; a first hydraulic telescopic cylinder is fixedly connected to the first connecting plate; the telescopic end of the first hydraulic telescopic cylinder is fixedly connected to the second connecting plate; several limiting rods are fixedly connected to the second connecting plate; under the limiting action of the limiting rods, four through holes are formed inside the film block package. After inserting a PE tube into the through holes, the heat in the film block package can diffuse to the inside of the PE tube, and then diffuse from the inside of the PE tube to the external environment, avoiding heat accumulation and spontaneous combustion. At the same time, the limiting rods are also used to fix the middle of the film block package, preventing the film block package from shifting during the opening of the side plates, thereby avoiding affecting the gripping and positioning operation of the robotic arm.
