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.

The objective of this invention is to provide a steering wheel that allows the driver to easily remove their fingers from a hole provided in the connecting portion, even if the driver's fingers become stuck in the hole. A hub is fixed to the steering shaft. Furthermore, when viewed axially along the hub, a rim portion for the driver to grip is disposed on the outer periphery of the hub, and the hub and rim portion are connected by a connecting portion. Holes with openings on the front side of the steering wheel are provided in the left and right connecting portions. The left and right connecting portions have inclined surfaces on the inner peripheral surfaces forming the holes, and these inclined surfaces are inclined such that the holes enlarge as they face the front side.
