Abstract

The invention relates to a method and a device for producing a high-grade highway protective guard framework material polyester industrial yarn, and in particular relates to a method and a device for producing the polyester industrial yarn through additionally arranging a passive outer circular blowing device. The production technological process comprises hyper viscous slicing-threaded rod fusing-fondant delivering through a pipeline-thermally insulating with a spinning manifold-accurately metering with a metering pump-spinning-thermally insulating with a rear heater-windless area slow cooling-cross air blow cooling-oiling with two oil wheels-godet-yarn path stabilizing with a pretension roller-pre-interlacing uniformly oil mixing-drawing-heat setting-stranding-interlacing beating-winding and forming, wherein the rear heater and the windless area are arranged into passive outer circular blowing pre-cooling; and the passive outer circular blowing pre-cooling refers to air natural cooling, and is a stainless steel rectangular frame, each side of the stainless steel rectangular frame is divided into four parallel equal areas, round holes are uniformly formed in the rectangular frame, the hole area accounts for 20-50% of the rectangular frame area, and the cooling height is 30-80 millimeters.

Description

technical field [0001] The invention relates to a production method and its device of a high-grade highway guardrail skeleton material polyester industrial yarn, in particular to a production method and a device of the polyester industrial yarn equipped with a passive outer ring blowing device. Background technique [0002] The high-grade highway guardrail is an indispensable basic facility on the high-grade highway, and plays a very important role in exerting the efficiency of the high-grade highway, preventing and reducing the occurrence of traffic accidents. High-grade highway guardrails should not only prevent out-of-control vehicles from rushing out of the road and colliding with obstacles or other facilities outside the road, or rushing through the central divider into the opposite lane to cause greater traffic accidents, but also enable the vehicle to return to its original state. In the normal driving direction, the damage to the driver and passengers is the least, a...
