Description

Extrusion foaming machine

Technical Field

The invention relates to an extrusion foaming machine.

Background

The foam plastic is a focusing body formed by dispersing gas in solid polymer, and is a product with higher application. Among them, PP (polypropylene) is the first choice material of foamed plastic due to its advantages of high rigidity, excellent mechanical properties, good chemical and thermal stability, good environmental suitability, easy recovery, etc., and is widely used as a heat-insulating and cushioning packaging material in the fields of high standards and high performance requirements such as automobiles, electronics, office stationery, etc. Since foamed plastic, particularly polypropylene, is an environmentally friendly material that is easily degradable, rigid, heat resistant, and easily recyclable, applications in the art of crafts, particularly on meal mats, are beginning to replace plastic meal cloths widely. The flat belt is a necessary raw material in the material for manufacturing and weaving the table mat, and particularly, the weight is reduced and the cost is greatly reduced after foaming, so the flat belt is more and more widely applied.

The extruder is a device for continuously mixing and extruding rubber and plastic, but the traditional extruder has a single extrusion forming device, cannot meet the introduction ports of various shaping dies, and can cause premature foaming and blockage of the introduction ports if forced introduction is carried out.
