| titleOfInvention | EVA grabs material device that hinders of system bubble |
| abstract | The utility model discloses a material blocking device for ethylene-vinyl acetate (EVA) bubble control, which comprises a ball nozzle, an injection head, a material conveying barrel and a material blocking cylinder, wherein the ball nozzle is of a cylindrical structure with a hemispherical front end, a through hole penetrating through the whole ball nozzle is formed in the ball nozzle, and the tail part of the through hole is provided with a conical surface. By adopting the technical scheme, the EVA bubble-restraining material blocking device provided by the utility model has the advantages that the through hole penetrating through the whole ball nozzle is formed in the ball nozzle, the time of EVA materials in the through hole is prolonged, only the foremost material is contacted with the air in the through hole in the plasticizing process, the peripheral surface of the material and the subsequently extruded material are not contacted with the air in the plasticizing process, the plasticizing process is finished when the material is extruded from the through hole, so that bubbles are hardly generated, and the product quality is greatly improved. |
