Degraded starch foaming machine

Abstract

The invention discloses a degradable starch foaming machine. The degradable starch foaming machine comprises a machine frame, an extrusion device, a granulator and a material receiving device, wherein the extrusion device and the granulator are arranged on the machine frame; the material receiving device is arranged on one side of the machine frame; the extrusion device comprises an extrusion device motor, a speed reducing box, a feeding barrel and an extruding machine; the extruding machine comprises a machine barrel, a single screw rod, a heater, a foaming machine head and a granulation hood; the granulator comprises a granulation motor, a granulation bearing, a bearing mounting seat and a granulation cutter disk; the material receiving device comprises a bracket, a fan, an air supply channel, a discharging pipeline and a material collecting bin; the granulation bearing and the single screw rod are arranged in parallel on the same side; the single screw rod is perpendicular to the disk surface of the granulation cutter disk; a cutter holder on the granulation cutter disk is aligned with an extrusion opening of the foaming machine head. The degradable starch foaming machine has the beneficial effects that the foaming machine has the advantages of reasonable structure, reliability in operation and efficient capacity; the yield of manufacturing materials can be guaranteed; the whole machine occupies a small space; parts are convenient to replace, and the service life is long.

Description

Technical field [0001] The invention relates to the technical field of foaming machines, in particular to a degradable starch foaming machine, which belongs to plastic processing equipment. Background technique [0002] Foam packaging materials are widely used in people's production and life. Traditional cushioning packaging materials are mainly made of polystyrene (PS), polyethylene (PE) and other general plastics. These general plastic foam materials consume limited petroleum on the one hand. Resources, on the other hand, pollute the environment. Commonly used foam packaging material waste treatment methods mainly include recycling, landfill and incineration. Among them, the waste foam packaging materials used for recycling are less than 1%; the landfill method will occupy land resources and cause pollution to the soil environment; the incineration method will cause serious pollution to the atmospheric environment. [0003] However, starch is a renewable resource with abundant ...
