A feed opening 3-1 is connect with outer 2 toroidal cavity of coating cup.Coating is through outer coating cup 2, from four feed opening 3- of interior coating cup 3
1 enter after coated on optical fiber.It is connect at one since outer coating cup 2 only has with coating pipeline 1, optical fiber coatings enter outer coating cup
It is attached on optical fiber after 2 through interior coating cup 3, it is seen that the active force of four feed opening 3-1 of interior coating cup 3 is different
(feed opening 3-1 and outer coating cup 2 discharge hole distance are closer, and suffered coating impact force action is bigger), so that optical fiber coatings adhere to
Unevenly, to make fiber coating diameter reach production requirement, when increasing coating pressure, fiber coating is in uneven thickness, thus
The physical appearance of optical fiber is caused eccentric phenomena occur.
Utility model content
The purpose of this utility model is to provide a kind of device for drawing optical fibers coating, such coating feeds four
The impact force in hole is identical, so that optical fiber can be secured firmly to center, prevents bias.
In order to solve the above technical problems, the embodiments of the present invention provides a kind of dress for drawing optical fibers coating
It sets, including interior coating cup, outer coating cup and 4 coating pipelines, wherein outer coating cup is sheathed on the outside of interior coating cup, and
The two forms the coating chamber for accommodating coating, opens up 4 first charging apertures, coating respectively in two two opposite sides of outer coating cup
Pipeline is connected to by first charging aperture with coating chamber, opens up 4 second charging apertures on interior coating cup, the position of first charging aperture and
The position of second charging aperture is corresponding.
The utility model embodiment in terms of existing technologies, is opened respectively by two two opposite sides in outer coating cup
If 4 first charging apertures, the impact force for flowing through second charging aperture by coating pipeline in this way is identical, so that optical fiber energy
It is enough secured firmly to center, prevents the bias of optical fiber.
In addition, other 2 first of the line of 2 first charging apertures of outer coating cup opposite side and outer coating cup opposite side
The line of feed inlet is mutually perpendicular to.
In addition, 4 first charging apertures are generally aligned in the same plane.
In addition, interior coating cup structure in a ring.
In addition, outer coating cup structure in a ring.
In addition, the shape of first charging aperture is consistent with the shape of second charging aperture.
In addition, first charging aperture is rounded.
In addition, second charging aperture is rounded.
Detailed description of the invention
Fig. 1 is the sectional view of applicator die in the prior art；
Fig. 2 is the sectional view of the applicator die in the utility model.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order to make the reader understand this application better, many technical details are proposed.But even if without these skills
The application technical side claimed also may be implemented in art details and various changes and modifications based on the following respective embodiments
Case.
The embodiments of the present invention is related to a kind of device for drawing optical fibers coating, as shown in Fig. 2, including interior painting
Apply cup 3, outer coating cup 2 and 4 coating pipelines 1, wherein outer coating cup 2 is sheathed on the outside of interior coating cup 3, and the two shape
At the coating chamber 4 for accommodating coating, 4 first charging aperture 2-1, coating are opened up respectively in two two opposite sides of outer coating cup 2
Pipeline 1 is connected to by first charging aperture 2-1 with coating chamber 4, and 4 second charging aperture 3-1, the first charging are opened up on interior coating cup 3
The position of mouth 2-1 is corresponding with the position of second charging aperture 3-1.
Specifically, interior coating cup 3 structure in a ring, outer coating cup 2 structure in a ring.First charging aperture 2-1 is opposite two-by-two
Be opened on outer coating cup 2, specifically, the line of 2 first charging aperture 2-1 of outer 2 opposite side of coating cup and outer coating cup 2
The line of other 2 first charging aperture 2-1 of opposite side is mutually perpendicular to.The line of i.e. every 2 opposite first charging aperture 2-1 is
