Energy-saving and environment-friendly screw extruder

Abstract

The invention discloses an energy-saving and environment-friendly screw extruder, relates to an extruder and aims to solve the technical problems that the extruder in the prior art is easy to block materials and waste the materials. The energy-saving and environment-friendly screw extruder is characterized by comprising an extruder body and a hopper arranged on the extruder body; at least two receiving plates are rotatably arranged in the hopper, the receiving plates are located at the lower part of a material inlet of the hopper, material conveying spaces for conveying the materials are keptbetween the receiving plates and the inner side wall of the hopper, the adjacent receiving plates are arranged in an up-down mode, the adjacent material conveying spaces are arranged in a staggered mode, and a power assembly is arranged on the hopper; when the materials need to be fed in, the materials are poured into the hopper and fall on the receiving plates, the power assembly drives the receiving plates to rotate, therefore, the speed of feeding the materials into the extruder body is controlled, and the materials may get into the extruder body smoothly; and thus, materials are reduced, which are all piled up at the hopper bottom, causing remaining materials; and extravagant materials are reduced, and the energy-saving and environment-friendly screw extruder is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to an extruder, more specifically, it relates to an energy-saving and environment-friendly screw extruder. Background technique [0002] Most plastic polymers have the advantages of light weight, stable chemical properties, no rust, good impact resistance, good transparency and wear resistance, so the rapid development of the polymer processing industry, and as one of the main processing equipment for polymers The advanced twin-screw extruder has been developed rapidly, and has been widely used for its excellent processing performance; the screw extruder relies on the pressure and shear force generated by the rotation of the screw, which can fully plasticize the material and Mix evenly and form through a die; plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screwless extruders. [0003] The Chinese patent with authorized notification number CN20391...

Problems solved by technology

[0004] When using the extruder in the prior art, the material is put into the hopper, and the material enters the barrel from the hopper, but in actual use, when adding the material, usually a variety of materials are added at the same time, and the material is fed from the feed port When entering the machine barrel, the material is easy to be blocked at the feed port, resulting in residual material in the hopper, wasting material, and needs to be improved
