Intelligent linkage control manner for production line of extrusion molding equipment

Abstract

The invention discloses an intelligent linkage control manner for a production line of extrusion molding equipment. The intelligent linkage control manner for the production line of the extrusion molding equipment comprises the following steps: 1) startup and predetermination; 2) automatic preheating; 3) material detection: an extruder hopper has a weight detection function for automatically identifying whether materials need to be added or not; 4) automatic extrusion; 5) production die-penetrating: working personnel work according to a standard working rule; 6) online monitoring; 7) automaticadjustment; 8) continuous production; 9) segment length early-warning; 10) speed reduction and stop; 11) scrap discharge; 12) automatic cooling; and 13) working stop. The running is continuous and manual intervention is not needed, adding for the materials in the hopper is accurately controlled, the temperature of a heating area is accurately controlled, the rotational speed and the discharge speed of a screw of an extruder are accurately controlled, the surface diameter of a wire cable is monitored on line and in real time, the surface defects of the wire cable are monitored on line and in real time, the surface temperature of the wire cable is monitored on line and in real time, and the water temperature of a water groove is adjusted, so that the product quality is effectively improved,the production efficiency is increased, and the automation degree is increased.

Description

technical field [0001] The invention relates to the field of automatic control of cable production, in particular to an intelligent linkage control mode of a production line of extrusion equipment. Background technique [0002] Existing extrusion equipment is in manual control mode during the cable production process. Before planned production, it is necessary to manually preheat the extruder 2 hours in advance. After the specified time, the operator checks whether the actual temperature of all temperature control areas meets the process design. Determine the temperature required by the process, and make a preliminary judgment on whether the material in the molten state of the die mouth meets the extrusion conditions. After all parameters meet the process requirements, perform screw extrusion discharge, and judge whether the cable is capable of passing through the die according to the characteristics of the raw material and the operator. Conditions, after the completion of t...
