Abstract

The invention relates coextrusion sheet material extrusion device, comprising coextrusion apparatus, five extrusion machines, speed reduction box, extrusion apparatus, activation motor and frame. Five extrusion machines are installed on frame, and connected with activation motor. The exits of five extrusion machines are connected with extrusion apparatus. The extrusion apparatus comprises coextrusion die and distributor which comprises shell, main feed inlet and discharge gate, the export of distributor is connected with the entrance of coextrusion die, in shell there is main flow passage connected with main feed inlet and discharge gate, the cross-section of main flow passage is rectangle, on shell there are four feed inlets, two feed inlets are connected with upside of main flow passage by branch flow passage, and the other two feed inlets are connected with downside of main flow passage by branch flow passage.

Description

technical field [0001] The present invention relates to an extruding device, more specifically to a co-extruded sheet material extruding device. Background technique [0002] Most of the existing co-extrusion sheet extrusion equipment uses 3 extruders to achieve the purpose of five-layer co-extrusion, so the processed sheet can only have 3 kinds of materials, and the co-extruded sheet can only be in the middle The layer is thick and the outer layer is thin. With the increasing requirements of the packaging industry for packaging materials, especially the food and pharmaceutical packaging industries have higher and higher requirements for freshness and shelf life, the sheets produced by the traditional three-machine five-layer co-extrusion sheet machine cannot effectively meet needs. Contents of the invention [0003] The purpose of the present invention is to provide a co-extrusion sheet extrusion equipment, which can co-extrude with five different materials. The technic...
