Embodiment 1

[0020] see figure 1 , figure 2 , image 3 , a dry-type optical fiber ribbon loose tube air blow molding device, the air blow molding device includes an extrusion device and an air blowing device, and the air blowing device includes an optical fiber ribbon conduit 1, a front positioning end cap 2, and an air blowing device tank body 3 , the rear positioning end cap 4 and the air supply assembly connected with the tank body of the air blowing device, the two ends of the tank body of the air blowing device are respectively provided with a front positioning end cap 2 and a rear positioning end cap 5, and the optical fiber ribbon conduit 1 runs through the entire Air-blowing device tank body; said extruding device comprises extruder head 6, extruder extruding outer mold 7, extruder extruding inner mold 8 and splitter cone 9, said extruder head 6 An extruder extruder outer mold 7 and an extruder inner extruder mold 8 are provided, and the extruder inner extruder mold 8 is arrange...

Embodiment 2

[0022] see figure 1 , figure 2 , image 3 , as an improvement of the present invention, the air blowing device further includes a polytetrafluoro gasket 4, and the polytetrafluoro gasket 4 is arranged between the tank body 3 of the air blowing device and the rear positioning end cap 5. This technical solution is equipped with a polytetrafluoroethylene gasket 4, which effectively plays a role of heat insulation and isolates the heat transmitted from the head of the extruder. And heat, avoiding the problem that the optical fiber ribbon is affected by high temperature before entering the machine head. The front and rear positioning end caps and the polytetrafluoro gasket 4 are connected with the tank body with countersunk bolts after being positioned by its flange surface. The dimensional tolerance of the optical fiber ribbon conduit is guaranteed to slide and fit with the front and rear end covers through processing, which is convenient for disassembly and assembly, and the ...

Embodiment 3

[0024] see figure 1 , figure 2 , image 3 , as an improvement of the present invention, the front positioning end cap is provided with an air outlet groove, which is convenient for gas to enter the gap between the splitter cone and the optical fiber ribbon conduit, and the air supply assembly includes an air source and a pipeline connected to the air source As well as the gas storage tank, pneumatic triple piece, filter and gas flow meter arranged on the pipeline, there is a gap between the splitter cone and the fiber optic ribbon conduit, and the extrusion inner mold of the extruder and the fiber optic ribbon conduit Set with gaps. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a dry optical fiber ribbon loose tube air blowing molding device. The air blowing molding device is characterized by comprising a plastic extruding device and an air blowing device; the air blowing device includes an optical fiber ribbon guide pipe, a front positioning end cover, an air blowing device tank, a back positioning end cover and an air supply component connected with the air blowing device tank; the front positioning end cover and the back positioning end cover are respectively arranged at two ends of the air blowing device tank; and the optical fiber ribbon guide pipe penetrates through the whole air blowing device tank. The device is skillful in whole structural design, can satisfy the production of both optical fiber small sleeves and optical fiber ribbon large sleeves, and is convenient for disassembly and assembly.

Description

technical field [0001] The invention relates to a forming device, in particular to a dry-type optical fiber ribbon loose tube air blowing forming device, which belongs to the technical field of optical fiber production equipment. Background technique [0002] The secondary coating process of the optical cable refers to the loose tube with the same length as the optical fiber ribbon on the outside of the optical fiber ribbon by the polymer material under the action of the extruder. The structure between the loose tube and the optical fiber ribbon is divided into filled type and fully dry type. The filled loose tube is filled with special fiber paste, and the dry type uses water blocking tape and compressed air to replace the fiber paste. The filled structure needs cleaning agent to clean the optical fiber during the optical fiber splicing process, which may not be clean enough and causes pollution. The corrosive cleaning agent and cleaning paper will affect the splicing qual...
