Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for wire and cable production, and discloses a core positioning device for cable production. Background Technology

[0002] The basic method for producing plastic insulation and sheath layers for wires and cables is to use a single-screw extruder for continuous extrusion. The insulation material is heated, stirred, and extruded by the machine body and screw, turning it into a viscous flow state. The plasticized insulation material is pushed into the die head by the screw and passes through the mold inside the die head, forming it into the extruded material of the required shape. After cooling and curing, it is made into wire and cable products.

[0003] To facilitate operation, there is a certain distance between the extruder's wire feeding device and the die head. After the wire core is led out from the wire feeding reel, it is easy for it to deviate after entering the die head due to gravity and the wire core's own swaying. This results in uneven thickness of the insulation layer and sheath layer, causing potential quality problems in the product and increasing manufacturing costs. Utility Model Content

[0004] In view of this, this application provides a core positioning device for producing cables, which solves the problem that there is a certain distance between the extruder's wire feeding device and the die head, and the core is prone to deviation after entering the die head due to gravity and the core's own shaking after being led out from the wire feeding reel. This results in uneven thickness of the insulation layer and sheath layer, causing potential quality problems in the product and increasing manufacturing costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
