Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a rubber strip extruder with an impurity removal mechanism. Background Art

[0002] 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 head can be divided into right-angle die head and bevel die head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through a die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screwless extruders. The rubber strip is extruded after the raw materials are put into the extruder, and then the rubber strip is directly cut and separated into particles before it is cooled. However, impurities are easily present in the material when the existing equipment is put into the material, and the existing impurity removal device is relatively cumbersome and prone to residues. Impurities easily affect the quality of the finished rubber strip.

[0003] Existing equipment is prone to leaving residues when removing impurities from raw materials. It is not possible to conveniently perform multiple screenings to remove impurities from materials, and it is not possible to guide the materials downward, causing accumulation or blockage during material feeding, affecting the equipment's impurity removal effect and the continuity of feeding.
