System and method for producing plastic products from recycled mixed plastic waste and plastic product

摘要

System and method for producing plastic products from a recycled plastic mix of unidentified, unclean and unsorted mixed plastic waste comprises the thermal and mechanical processing of the recycled plastic waste using continuous extrusion foaming, two-phase cooling, continuous metering of the pulling strength and automatic adjustment of the pulling speed and extrusion speed.

1. A system for producing plastic products from recycled mixed plastic waste comprising:
a system for mixing raw materials, a first conveyor, a hopper, a second conveyor, a fine mixer with a weighing system, a control panel, an extruder, a system of calibration matrices on a calibration table, a water-cooling bath, a pultrusion machine with a converter, and an electric motor with a reducer, and an automatic cutter, wherein: the extruder comprises a motor; a gearbox; a frame; cooling ventilators; a screw that has a feeding zone, a compression zone, and a mixing zone; a barrel that includes multiple heating zones; an extrusion head; a die; and a head extension that is also used as the first cooling zone; the system of calibration matrices comprising a first calibration matrix that is connected to the extrusion head extension; a second calibration matrix, third calibration matrix, a fourth calibration matrix, each of the calibration matrices comprising a bottom, a lid and two sides and each calibration matrix being rigidly fixed to one another, thus forming an inner chamber of the matrices; and cooling channels; and the pultrusion machine constantly measuring pulling strength and pulling speed and adjusting extrusion speed automatically.
