Description

Technical Field

[0002] PE is polyethylene. Generally, the application range of PE pipe water supply pipeline is below 40℃, and it cannot be used for hot water delivery pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin cross-section. PE has excellent resistance to most domestic and industrial chemicals. For this reason, PE pipes are widely used in all walks of life. PE pipes are extruded by an extruder, and the extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the materials, and then form them through the die. While the PE pipe extruder is working, a feeding device is required to feed the extruder to prevent the extruder from stopping.

[0003] For example, in the prior art, a feeding device of an extruder for producing PE pipes is provided, in which a spiral feeder body is fixedly installed through the bottom of a feed hopper, the discharge port of the feed hopper is communicated with the feed port on the spiral feeder body, a fixed frame is fixedly installed on the outer surface of the feed hopper, and support legs are fixedly installed at the four corners of the bottom of the fixed frame. The feeding device of the extruder for producing PE pipes supports the spiral feeder body through a support rod, and reinforces the support rod with a fixed rod so that the force on the support rod is evenly distributed on the base, and then two positioning rods are used to fix the support rod between the two support legs, thereby forming a stable triangle, further reinforcing the position of the support rod, and avoiding the support rod from being unevenly stressed when the feeding device moves, resulting in bending, thereby achieving the supporting effect.

[0004] However, when the device is in use, the height of the discharge port is fixed, and when different PE pipe production extruders need to be fed, it cannot be adapted, which reduces the adaptability of the PE pipe production extruder feeding device.
