Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe processing, in particular to a tubular object melting extruder. Background Art

[0002] In the processing of plastic pipes (such as PVC pipes, PPR pipes, etc.), the tubular melt extruder can heat plastic particles (such as PVC resin) to a molten state, and through the rotation and shearing action of the screw, the melt is mixed evenly. The molten plastic melt is extruded into a tube through a mold.

[0003] An environmentally friendly extruder disclosed in the existing patent announcement number CN210820843U has a water inlet pipe arranged on the side of the extruder body to pass water into the interior of the extruder body. The water and plastic are blocked by the reverse screw section inside the extruder body, and are thus fully extruded and mixed by the dense screw section. Subsequently, the harmful gas is released in the long screw section. At the same time, the interlayer of the extruder body is heated to form water vapor, which is mixed and dissolved with water-soluble gases such as VOCs in the harmful gases released by the plastic. The remaining harmful gases are separately extracted by the exhaust pipe arranged on the extruder body to prevent the harmful gas from flowing out of the discharge port and causing pollution to the operator's surrounding environment.

[0004] When processing plastic pipes, the above device directly pours the raw materials into the extruder body. After feeding, the materials are easily accumulated at the feeding end, resulting in uneven mixing of the materials and affecting the extrusion of the plastic pipe. To address the above problems, a tubular melt extruder is proposed. Utility Model Content
