Description

Technical Field

[0001] The present application relates to the field of cable production, and in particular to an extruder head mold with automatic deviation adjustment. Background Art

[0002] The current single-layer extrusion molding device for insulated wires is to coat the core wire surface with an insulating skin. The eccentricity determines the quality of the insulated wire. If the thinnest point is smaller than the standard, after long-term use, the thinnest point will definitely have the weakest resistance to mechanical stress and chemical substances, and will be the first to break. The more layers there are, the more difficult it is to make, such as double-layer extrusion and three-layer extrusion. At present, the main control method for the eccentricity of the extrusion process of the insulated wire is the online eccentricity detector. When a problem occurs, the locking screw of the die head is manually adjusted. The online eccentricity detector can only detect and display the eccentricity of the extrusion online, and cannot be adjusted automatically. It is necessary to manually observe the eccentricity and manually adjust the locking screw of the extrusion die of the die head to adjust the eccentricity. There are problems such as dependence on the experience of professionals, slow adjustment speed, many startup wastes, and inability to adjust dynamically in real time. It has an impact on the overall efficiency of production, product quality and the rational use of materials. Summary of the invention
