[0002] The ointment filling method of the traditional optical cable adopts a fully-filled water-blocking structure. The ointment of the optical cable uses pressure to fill all the gaps in the cable core, so as to achieve the full-section water-blocking effect of the optical cable. This process consumes a lot of cable ointment and requires Only when the filling fullness reaches more than 95% can the water seepage performance of the optical cable be qualified, and after encountering water, the water molecules can only combine with the water expansion factor on the surface of the cable paste to expand and block the waterway. The expansion speed is slow and the expansion height is low, resulting in water The lengthening of the flow process in the cable core affects the water blocking effect

Embodiment Construction
[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0010] like figure 1 As shown, the optical cable water-blocking paste spray filling equipment adopted by the method of the present invention includes a stranding cabin 8, and the stranding cabin 8 is connected with a cable core yarn binding device 3, and the cable core yarn binding device 3 is a two-way cable core yarn binding device. The cable core yarn binding device 3 is provided with a twisting and sizing die 2, which is connected to the stranding cabin 8, and the stranding cabin 8 is provided with a wire passing plate 4, and the wire passing plate 4 reaches the cable core tie. The yarn devices 3 are separated into a relatively closed twisting cabin 8, the wire passing board 4 is a wire passing board for twisting elements, and the twisting cab...

The invention discloses a method for filling optical cable water-blocking paste of atomization type filling factice. The method comprises the following steps: cable core twisting elements are led to a pass line board to be gathered together, are threaded through pass line holes on the pass line board, and are twisted at a twisting sizing mold at certain intervals; and the factice is ejected to the cable core twisting elements in a twisting cabin by using a factice gun; the cable core twisting elements with the factice mist are enabled to enter a twisting sizing mold so as to be twisted; after being twisted, the cable core twisting elements enter a cable core yarn bundling device, and are bundled and fixed by the cable core yarn bundling device so as to form the cable core. The atomized cable paste on the surface and the gaps of the optical cable core prepared by using the method has relatively larger penetration and smaller viscosity, is rapid in water absorption speed, and has relatively higher expansion height and gelation ability, so that the water-blocking of the optical cable in the radial and longitudinal directions is effectively realized, the use quantity of the cable paste is greatly saved, and moreover the manufacturing cost and the unit optical cable weight of a product are reduced; and furthermore the paste is easy to clean and convenient to construct and operate.
