Technical field
The utility model belongs to optical fiber coating technical field, particularly a kind of optical fiber open type coating unit.
Background technology
Optical fiber structure is from inside to outside: quartzy sandwich layer and covering, outside applies coating as protective layer.The intensity of optical fiber and surface smoothness, homogeneity, be mainly subject to coating method, the impact of pressure when coating temperature and coating.
Existing communication fiber drawing tower drawing speed is many more than 1200m/min, is applicable to adopting pressure coating device.Coating die is from external import, and drug delivery medical device structure place has heating in water bath circulation to guarantee coating homo(io)thermism, and the pressure of coating is by constant pressure is all the time set on computer while guaranteeing wire drawing.
Large core fiber production rate is slow, and general speed is between 2m/min to 30m/min, and it is not ideal that pressure coating device applies effect at fiber core 600 μ m when above, therefore adopt open type coating unit more.
If wire-drawer-tower simultaneously setting pressure applies and two kinds of devices of open type coating, can only increase the height of wire-drawer-tower or each member distance on wire-drawer-tower is compressed.Increase wire-drawer-tower height equipment cost, the increase of factory building cost, optical fiber is exposed to the lengthening of air middle distance in addition, has increased the impact of fine particle on optical fiber quality in air; On wire-drawer-tower, each member distance compression, is unfavorable for wire-drawing operation, strengthens the probability of mal-operation.
Open type coating unit, is fixed on wire-drawer-tower by drug delivery medical device.A small powder cup has coating, and in material cup, coating is along with fibre-optical drawing length increases, and liquid level declines very fast.When drawing optical fiber starts like this and after drawing one section, optical fiber exports i.e. coating place at material cup, and the pressure being subject to has some to change, thereby cause applying rear fibre diameter, changes.
Optical fiber coatings has a best application temperature, and existing open type coating unit only has a material cup, by paint heating in water-bath or alternate manner material mixing cup, makes it be stabilized in best application temperature.In the time will being increased to material cup from other local feeding, just need to guarantee that the coating increasing is also in this temperature.Otherwise after adding, coating temperature variation, viscosity is just changed, thus impact applies rear fibre diameter.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of optical fiber open type coating unit, utilizes existing wire-drawer-tower pressure coating support, manufactures a material cup and places wherein, and by pipe connecting, the cup of getting the raw materials ready of one large bottom surface is communicated with material cup; Pipe connecting and the cup of getting the raw materials ready are all wound around nichrome wire, by temperature regulating device, control this two places temperature; Coating die is placed in material cup bottom, needs the optical fiber applying to be passed through by the circular hole on coating die, thereby apply, coats.
The utility model solves the technical scheme that its technical problem adopts: a kind of optical fiber open type coating unit is provided, comprise material cup, get the raw materials ready cup and coating die, described material cup upper end and getting the raw materials ready is connected by pipe connecting between cup, end, described material cup lower end has been nested with coating die, described coating die bottom has and the circular hole of expecting that glass hollow space communicates, and described optical fiber applies material loading through material cup hollow space at circular hole place.
Described ratio of getting the raw materials ready the floorage of cup and the floorage of material cup is 10:1, described in the distance of getting the raw materials ready between cup bottom and pipe connecting be 1-5mm.
The described cup of getting the raw materials ready is tied with nichrome wire with the outside of pipe connecting, and described nichrome wire is controlled by temperature regulating device.
The pressure coating supporting structure by heating in water bath is put in described material cup lower end, and the outside of described material cup lower end has two U-shaped grooves, in described each U-shaped groove, is placed with rubber ring.
beneficial effect
The utlity model has following advantage and positively effect:
1. material cup can directly be put into existing wire-drawer-tower pressure coating supporting structure, and upper part assurance material cup that rubber ring and material cup are larger is placed stable, and in the heating in water bath assurance material cup of drug delivery medical device structure, coating temperature is even;
2. material cup upper and lower opening area is little, and glass base area of getting the raw materials ready is large, and while adding coating material production, optical fiber coating can be subject to the pressure change that coating liquid level declines and causes hardly, thereby has guaranteed that coated fiber is even.
