Fiber paste pre-filling device for optical fiber ribbon plastic shield prebalelling

Abstract

The invention discloses a fiber paste pre-filling device for optical fiber ribbon plastic shield prebalelling. The fiber paste pre-filling device comprises a seal cover, an inner core and a wire separating device. The inner core is arranged inside the seal cover in a rotatable mode. A circular groove is formed in the peripheral surface of the inner core. A fiber paste runner is formed by the circular groove and the inner ring surface of the seal cover. The fiber paste runner is communicated with a fiber paste inlet. The wire separating device is fixedly connected with the inner core and is coaxial with the inner core. Besides, the wire separating device is arranged outside the seal cover, and a fiber paste overflow hole is formed in the inner side wall of a wire separating cavity of the wire separating device and communicated with the fiber paste runner through a pipeline. In addition, the wire separating device is provided with a cover plate, wherein the wire separating cavity can be opened through the cover plate. In this way, the fiber paste pre-filling device for the optical fiber ribbon plastic shield prebalelling can solve the problems that in the fiber paste pre-filling process, optical fiber ribbons are disordered, the obverse sides and the reverse sides of the optical fiber ribbons are incorrectly arranged and adverse effects are caused to the attenuation coefficient of the optical fiber ribbons; moreover, the fiber paste pre-filling device for the optical fiber ribbon plastic shield prebalelling can effectively reduce labor intensity of workers, and is convenient to clean.

Description

technical field [0001] The invention relates to the technical field of optical fiber processing, in particular to an optical fiber tape sleeve plastic fiber paste pre-filling device. Background technique [0002] The optical fiber ribbon coating process is one of the most important links in the optical fiber production process. The optical fiber ribbon coating process refers to overlapping multiple optical fiber ribbons, and then covering the outside with a layer of PBT (polybutylene terephthalate) Ester) material, filled with fiber paste in the middle, fiber paste is a transparent paste-like substance, which has the function of protecting and water-blocking the optical fiber ribbon. [0003] Before the optical fiber ribbons are overlapped together, a layer of fiber paste should be applied to each optical fiber ribbon, and then overlapped together, so that the lubrication between other optical fiber ribbons can be achieved, and then multiple optical fiber ribbons enter the P...

Problems solved by technology

[0005] However, during the use of the optical fiber ribbon sleeve plastic fiber paste pre-filling device in the prior art, it is inconvenient to thread the optical fiber ribbon. It is necessary to remove the branching mold in advance, then pass all the optical fiber ribbons through the filling device, and then insert the optical fiber ribbon Pass through the branching device, and then insert the branching device into the filling device, which will easily cause confusion in the order of the optical fiber ribbons, mistakes in front and back, and high labor intensity for employees

[0006] Moreover, due to the relative movement between the fiber paste and the optical fiber tape during the production process, the fiber paste and the optical fiber tape increase the production resistance of the optical fiber tape and affect the attenuation coefficient of the optical fiber tape.

[0007] Therefore, how to solve the problems of chaotic order of optical fiber ribbons, positive and negative errors, high labor intensity and easy influence on the attenuation coefficient of optical fiber ribbons in the fiber paste pre-filling process in the prior art has become an important problem to be solved by those skilled in the art. technical problem
