Embodiment
The curing air exhausting device of this improvement fibre coating UV solidifies silica tube lower valve by UV and the curing draught hood of UV forms, UV solidifies draught hood and the curing silica tube lower valve of UV is arranged on respectively on the upper and lower bottom plate of UV lamp box, the two ends that UV solidifies silica tube are connected with valve seal frock with draught hood respectively, described UV solidifies silica tube lower valve and passes into hole 1 by solidifying protection gas, moving slider 2, slide block gag lever post 3, lower valve hole 4, base plate standing bolt 5, slide block standing bolt 6, base plate 7, the logical optic fibre hole 8 of base plate forms, base plate 7 is packed in the bottom of UV curing oven by base plate standing bolt 5, base plate 7 central authorities are manufactured with the logical optic fibre hole 8 of base plate of a 24mm diameter, one side of base plate 7 is manufactured with to solidify protects gas to pass into hole 1, one end of two moving sliders 2 is movably fixed to the top of base plate 7 by slide block standing bolt 6, leave the gap of 0.05mm between slide block standing bolt 6 and base plate 7, by this gap moving slider 2, can on base plate 7, slide, the middle inside of two moving sliders 2 is manufactured with respectively the semicircle orifice that a radius is 4mm, after two complete closures of moving slider 2, form the lower valve hole 4 that a diameter is 8mm, the bottom of the logical optic fibre hole 8 of base plate of base plate 7 is provided with slide block gag lever post 3, and the rotation of 3 pairs of moving sliders 2 of slide block gag lever post is carried out spacing.Described UV solidifies draught hood and consists of the curing draught hood main body 9 of UV, the logical optic fibre hole 10 of draught hood and measuring wind speed hole 11, on the right-hand member of the curing draught hood main body 9 of UV, being provided with a diameter is the logical optic fibre hole 10 of draught hood of 15mm, on the left end of the curing draught hood main body 1 of UV, is provided with the measuring wind speed hole 11 that a diameter is 14mm.(referring to attached Fig. 1 and 2)
This working process of improving the curing air exhausting device of fibre coating UV is as follows:
The working process that UV solidifies silica tube lower valve is: in optical fiber high-speed wire-drawing production process, the optic fibre hole that solidifies silica tube lower valve due to UV is smaller, and affected by wire-drawer-tower collimation situation and can cause optical fiber in drawing process, very easily to clip the optic fibre hole of UV silica tube lower valve, cause optical fiber external coating (EC) to scratch and cause tower disconnected, along with popularizing of large size prefabricated excellent wire-drawing technology, single prefabricated stick drawn wire length is often more than 3000KM, so the wire drawing time of single prefabricated rods often will surpass more than 24 hours, so just cause the passing along with the wire drawing time, the quartzy volatile matter producing in pipe that solidifies of UV can get more and more, even at UV, solidifying 4 places, silica tube lower valve hole piles up, optical fiber outward appearance and intensity are impacted.By mobile moving slider 2, control the usage quantity that UV solidifies protection gas; in production process, moving slider 2 is completely closed; by expanding the lower valve hole 4 on moving slider 2; make needn't worry, because volatile matter deposition causes, the friction of optical fiber is caused to optical fiber Appearance quality defect in production process; and close completely behind this valve hole, can reduce the waste of shielding gas.
The working process that UV solidifies draught hood is: in optical fiber high-speed wire-drawing process, by solidify the measuring wind speed hole 11 of offering in draught hood main body 9 at UV, can to current curing exhausting wind speed, measure at any time in process of production, and at any time by regulating the closed degree of valve on air draft pipe to regulate exhausting wind speed, by measuring exhausting wind speed every day, can be steady in a long-term exhausting wind speed is controlled to a stable interval, can accurately control optical fiber curing degree, reduce because optical fiber curing is bad and overcuring causes substandard product.
The above is preferred embodiment of the present utility model, above-mentioned not illustrating done any pro forma restriction to flesh and blood of the present utility model, any simple modification or distortion that person of an ordinary skill in the technical field has done above embodiment according to technical spirit of the present utility model after having read this specification sheets, and the technology contents that may utilize above-mentioned announcement is changed or is modified to the equivalent embodiment of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
