Description

Pipe extruder for producing inner spiral runner PE water pipe and working mode of pipe extruder

Technical Field

The invention relates to the field of pipe extruders, in particular to a pipe extruder for producing an inner spiral runner PE water pipe and a working mode thereof.

Background

At present, the PE water pipe of the internal spiral flow passage is more and more widely applied to a vertical drainage system. Under the guiding action of the spiral protrusion on the inner wall, water flow falls along the pipe wall in a spiral shape, so that the noise in a pipeline system is greatly reduced, the silencing effect is achieved, a smooth air column is formed in the center of the water pipe during drainage, the ventilation capacity is improved, the pressure in the pipe is reduced, and the drainage capacity is increased. The existing pipe extruder is generally used for producing common round pipes and cannot be used for producing pipes with spiral flow channels inside. Therefore, a pipe extruder for producing the PE water pipe with the internal spiral flow passage is needed.

Furthermore, the shaping structure comprises a shaping cylinder, a cooling chamber and an outer cylinder, wherein the outer wall of the shaping cylinder and the inner wall of the outer cylinder form the cooling chamber. The shaping process of the spiral pipe is accelerated.

Further, the machine head and the shaping device are directly provided with sealing rings. The compressed air entering from the first vent hole of the machine head is prevented from overflowing in the shaping process, so that the shaping of the spiral pipe is influenced.

Further, a working method of the pipe extruder for producing the PE water pipe with the internal spiral runner comprises the following specific steps:

1) the raw material of the pipe enters a machine barrel of an extrusion system from a feed inlet and is melted under the action of a cast aluminum heater;

2) the power system drives the screw of the extrusion system to rotate, and the molten pipe raw material is driven by the screw to move towards the connector;

3) the melted tube raw material enters a machine head, and under the mutual extrusion of a splitter bracket, a splitter, a neck mold and a core rod, the tube with the geometric section and the shape meeting the requirements is obtained;
