Embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
Before wire drawing begins, be coated with dressing valve 1 and be in closing condition, because speed is that the zero resistance silk does not heat feed pipe; After wire drawing began, valve was opened automatically, and coating begins to flow; Nichrome wire heats according to the setting of PLC gradually; Because the optical fiber external diameter is generally all bigger under the low speed,, scrap otherwise can cause too many optical fiber external diameter to exceed standard so pipe temperature can not be set too highly during low speed; When drawing speed raise, in order to mate the two-layer viscosity and increase optical fiber external diameter that is coated with dressing, applying the pipe material temperature can raise according to the set(ting)value of PLC; When speed reduced, nichrome wire can reduce heating power or not heat, and makes pipe temperature naturally cool to target value; When wire drawing finished, valve cut out automatically, and nichrome wire stops heating, and the coating in the pipeline naturally cools to normal temperature.Generally speaking, the last feed pipe 5 of the first layer coating need not heat.The starting velocity of pipeline heating is generally 300 ~ 400m/min.
