Abstract

The invention provides a continuous EPE physical foamed plate extruder which comprises a first-stage extruder body, a second-stage extruder body and a pipeline. The first-stage extruder body comprises a first-stage screw barrel and a first-stage screw. The second-stage extruder body comprises a second-stage screw barrel and a second-stage screw. The first-stage screw barrel and the second-stage screw barrel communicate through the pipeline. The continuous EPE physical foamed plate extruder is characterized in that the first-stage screw sequentially forming a first feeding section, a barrier section, a first stirring section and a first mixing section in the axial direction. A plurality of pin sets are arranged on the screw groove surface of the pin stirring section. According to the continuous EPE physical foamed plate extruder, product quality can be improved while the yield is increased and production efficiency is improved, and production energy consumption can be reduced.

Description

technical field [0001] The invention relates to an extruder, in particular to a continuous EPE physical foam sheet extruder. Background technique [0002] Extruders are commonly used equipment for plastic processing machinery, among which extruders for the production of EPE (polyethylene foam) physical foamed sheets are a very typical type. In order to improve the quality of extruded products and shorten the length of a single screw, a single-screw tandem extruder has appeared in the prior art, and its typical structure is CN203391275U (name: double-feed single-screw tandem extrusion) Machine) The technology disclosed in the Chinese patent; this technology has been improved on the basis of the traditional single-screw tandem extruder, mainly because the first barrier section and the second barrier section are respectively set on the first-stage screw and the second-stage screw , the function of the two barrier sections is: it can prevent the solid phase in the material from...
