Description

Technical Field

[0001] The utility model relates to the technical field of MPP pipe processing devices, in particular to an MPP pipe production and processing extrusion device. Background Art

[0002] MPP pipe, also known as MPP power cable protection pipe, is a new type of polymer material pipe widely used in power, communication and other fields. It has high temperature resistance, external pressure resistance, excellent electrical insulation performance, high heat deformation temperature and low temperature impact performance. In the production and processing of MPP pipe, extrusion molding is a key step. When performing extrusion molding operation, it is usually carried out on the corresponding processing extrusion device. This type of processing extrusion device is usually equipped with a discharge pipe, so that the MPP pipe can be extruded outward along the discharge pipe to complete the preparation operation.

[0003] However, due to the high temperature of the MPP tube just prepared by extrusion, it will be difficult for the MPP tube to maintain its shape if the temperature is too high, and the high temperature will also affect the performance of the MPP tube. This type of extrusion device lacks components that can cool the MPP tube, and timely cooling operations cannot be performed; although some extrusion devices are equipped with cooling operations, the cooling devices use a direct and rapid cooling method to cool the temperature, and cannot achieve a gradual cooling operation from front to back, which will also cause the MPP tube to affect the stability of its internal performance due to the rapid temperature drop. In view of this, we propose an MPP tube production and processing extrusion device. Utility Model Content
