▎ 摘　　要

NOVELTY - The extruder has a machine frame (1), whose end is provided with a cooling module. The machine frame is fixedly installed with a transmission motor (2). Two ends of the cooling module are fixedly connected with a charging barrel through a pipeline. The gear box is fixedly installed with a control platform (3). The one end of the outer cylinder is fixedly installed with a machine head connector (6). The charging barrel comprises a cylinder body, a connecting cylinder, a cooling liquid inlet, cooling liquid temporary storage cavity, a flow passage butt interface, a mounting groove, connecting flange, a wearable mechanism, a graphene heat conducting cylinder, a heating body placing groove, cooling cavity, and cooling liquid outlet and a filling mechanism. The cylinder body corresponding to position of cooling cavity fixedly installed with telescopic rod. The cylinder body is fixedly installed with a heat-conducting sealing block. An end of a telescopic rod close to a gear box (4). USE - Ethylene vinyl acetate (EVA) plastic film extruder for use in plastic extrusion molding device. Uses include but are not limited to pipe, film, monofilament, flat wire, packing belt, plate material, sheet material, profile, granulating, cable coating and various plastic forming auxiliary machines. ADVANTAGE - The material cylinder realizes the fast heating material cylinder, avoids energy waste, improves the heat conducting performance of the base, also realizes fast cooling of the material cylinder and avoids the cooling medium flow channel set in the heating. The heat needs to heat the cavity to indirectly conduct the heat to the plastic particles in the material, which greatly reduces the heat-conducting performance of material cylinder. The contrast patent is optimized, further improving the heating efficiency. The inner surface of wearable cylinder is coated with a wearable layer for improving wear resistance of the wearable cylinder, and the service life of wearable mechanism is prolonged. When the wearable mechanism changes, because the limiting sheet set outside wearable mechanism needs to be aligned with the limiting groove, reducing the replacing efficiency of a wearable mechanism, by setting the first mounting mark area matched with the second mounting area, realizing fast DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the ethylene vinyl acetate plastic film extruder.
