Description

An EPDM runway granule extruder

Technical Field

The utility model relates to the technical field of industrial production, in particular to an EPDM raceway particle extruder.

Background Art

EPDM is a synthetic rubber, the full name is ethylene-propylene rubber. It is a copolymer composed of ethylene, propylene and diene monomers, with excellent physical properties and resistance to chemical corrosion, oxidation, high temperature and weathering. EPDM rubber can be divided into two types: non-cross-linked type and cross-linked type.

An extruder is a machine that uses a motor to drive the screw to rotate to generate extrusion force, thereby deforming the material and mixing multiple materials.

Extruder is a type of plastic machinery. According to the direction of the material flow in the die and the angle between the center line of the screw, the die can be divided into right-angle die and bevel die. The screw extruder used in the production of EPDM rubber particles is generally a single-screw extruder, which has the advantages of simple structure, easy manufacturing and high processing efficiency.

The existing technology has the following problems:

1. The existing EPDM runway granule extruder has a poor crushing effect on the EPDM granule raw materials during use, resulting in low quality and poor practicality of the extruded rubber granules. At the same time, accumulation often occurs during feeding, resulting in incomplete feeding of materials into the extruder;

2. In the existing EPDM track particle extruder, the EPDM particle raw materials are unevenly heated in the extruder and easily form bubbles, resulting in inconsistent uniformity of the extruded particles, which in turn causes the low quality of the produced rubber particles and reduces the quality of the plastic track processing.
