Cable extruder head

Abstract

The invention discloses a cable extruder head, comprising an extruder head body, wherein the extruder head body is of a conical structure; outer membrane groups are arranged on the upper surface and the lower surface of the extruder head body; each outer membrane group is composed of a gap between two adjacent outer membrane rings; the outer membrane groups are fixed on the extruder head body; a cylinder is connected between the outer membrane group on the lower surface of the extruder head body and the extruder head body, and is fixed between the extruder head body and the outer membrane group; a cooling jacket is arranged on the lower surface of the outer membrane group on the lower surface of the extruder head body, clads the outer membrane groups and the cylinder, and is made of a stretching material; and at least two inner cores are transversely arranged in the extruder head body. The cable extruder head is capable of achieving once molding and extruding of a plurality of layers of cables, processing the cables according to the actual requirements, and effectively meeting the pressure requirements of liquid rubber, so that the cable extruder head is not easily blocked, and meanwhile, the problem of low working efficiency caused by repeated processing of the cables can be avoided, and the problem of surface damages caused by processing the cables for a plurality of times can be avoided.

Description

technical field [0001] The invention relates to a machine head, in particular to a cable extruding machine head. Background technique [0002] The extruder is a necessary equipment in the production process of wires and cables. With the advancement of engineering technology, the requirements for wires and cables in different engineering sites have also increased, such as waterproof, anti-static, etc., and the demand for wires and cables is large. Requirements Work efficiency should also be further improved. In order to ensure the safe use of wires and cables, the outside of the cable is wrapped with an insulating layer. The insulating layer is generally a double-layer structure. Two extrusion methods are used to complete this structure. One is double-layer co-extrusion. Although the process of double-layer co-extrusion is Simple, high production efficiency, but because the two-layer insulation structure is cooled at the same time and some insulation materials are relatively...

In order to ensure the safe use of wires and cables, the outside of the cable is wrapped with an insulating layer. The insulating layer is generally a double-layer structure. Two extrusion methods are used to complete this structure. One is double-layer co-extrusion. Although the process of double-layer co-extrusion is Simple, high production efficiency, but because the two-layer insulation structure is cooled at the same time and some insulation materials are relatively viscous, it is easy to cause uneven thickness; the other is to extrude twice, but this process is more complicated and the production range is limited. , and such an extruder head cannot process cables better, resulting in low work efficiency
