Abstract

The invention aims to provide a halogen-free cable production system with flame retardant. According to the technical scheme, the halogen-free cable production system is composed of cable core production equipment, a plurality of process output devices, a lining processing device, an insulation layer packaging device, a flame retardant layer processing system, a steel belt packaging machine and protective jacket packaging equipment. The flame retardant layer processing system is further provided with a drying machine, an antiflaming extruder and a cooling device. According to the cable production system, air holes can be prevented from being formed in the fracture surface of a cable product under the effect of the drying machine in the flame retardant layer processing system, and the phenomenon that auxiliaries are decomposed due to the excessively-high temperature, and thus the air holes can be formed in the product aims to be prevented by cooling; if the temperature is too low, bad plasticizing can happen. The dried cable enters the antiflaming extruder to be processed, and a double-order mixing extruder which is combined by a single screw and double screws is selected to be used in the antiflaming extruder. Through the two key processes, the material performance on the aspects of being resistant to ageing, ultraviolet light and other irradiation of the assembled cable is greatly improved, and therefore the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a halogen-free cable production system with a flame retardant. Background technique [0002] Cable conductors use copper conductors or aluminum conductors. The production process of cable products in the past is not very complete. There are often two or more welding points in cable conductors. According to the provisions of GB / T3956 "Cable Conductors"; Finished conductors are not allowed to be repaired after whole root welding, single wire welding or twisting. Bundled or stranded conductors should be rounded and evenly spaced, and there should be no broken wires, missing roots, missing strands, or loose strands. In order to avoid this phenomenon, the cable production system is equipped with a dryer and a cooling device in the flame retardant layer processing system. Due to the poor fluidity of the material and the high frictional resistance with the equipment, o...
