Abstract
This utility model relates to the technical field of polyethylene foam processing equipment, and more particularly to a twin-screw integrated mixing and extrusion device for polyethylene foam. It includes a base plate and a mixing extruder body fixedly mounted on the base plate. The mixing extruder body has a mixing chamber and two extrusion chambers. Two screws are horizontally rotatably mounted on the mixing extruder body, and the screws are rotatably installed in the mixing chamber and the extrusion chamber. Multiple sets of mixing components are mounted on the screws, and auger blades are fixedly sleeved on the screws, with the auger blades rotatably disposed in the extrusion chamber. This utility model integrates mixing and extrusion functions into one device. Through the rotation of the twin screws, in conjunction with the mixing components and auger blades, polyethylene foam formulations can be mixed and extruded simultaneously, avoiding the transfer of materials between different devices, greatly shortening the production cycle and improving production efficiency.
