Stability determines the property indices of optical cable, and with urban duct resource growing tension, the optical fiber dense degree to optical cable will
Ask higher, the stability of sleeve structure size seems more and more important.In existing technology, during high-speed production, in extruder head
Easily bring air into, cause in the sleeve pipe of extrusion molding, to produce substantial amounts of bubble, external diameter is difficult to stability contorting, cause product bad and
Waste of raw materials, also affects the moral character of optical cable.
Utility model content：
The purpose of this utility model is to provide a kind of optical cable extrusion molding Vacuuming structure, and simple structure, for sleeve pipe
Production, makes the physical dimension of production rear sleeve more accurate, stable.
For reaching above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of optical cable extrusion molding Vacuuming structure, includes extruder head, and the extruding end of extruder head is provided with die cap
And core rod, plastic passages are left between die cap and core rod, the arrival end of extruder head is assembled with needle tubing, and one end of needle tubing extends inserts
Enter core rod, the endoporus of needle tubing is for optical fiber and ointment while pass through, plastic passages extrusion of the moulding plastics between die cap and core rod
And wrap up optical fiber and ointment, that is, sleeve pipe is made, the arrival end of the extruder head is provided with vacuum part, and the respective end of needle tubing is exposed very
Outside empty part, the vacuum part have vacuum chamber and connect with vacuum chamber vacuumize hole, after vacuum part assembling, its vacuum chamber connects pin
Space between pipe and core rod, forms vaccum supply system.
In such scheme, the vacuum chamber of the vacuum part is groove structure, and in vacuum chamber, bottom is provided with through hole, and the through hole supplies pin
Pipe wears and exposes.
In such scheme, installing hole on the vacuum part, is additionally provided with, installing hole is around the distribution of vacuum chamber periphery, respective screws
Vacuum part is fixed on extruder head by installing hole.
A kind of optical cable extrusion molding Vacuuming structure that the utility model is provided, is provided with very in the arrival end of extruder head
Empty part, is formed a closed space with extruder head, core rod, is aspirated with appropriate suction force from hole is vacuumized, and will be squeezed
Go out the gap of air that the extruding end of head brings into from needle tubing with core rod to discharge, the bubble in production rear sleeve is reduced, so
Ensure that the external diameter of sleeve pipe is more stable.The utility model simple structure, small volume, easy to use, contribute to the life of optical cable
Produce, Improving The Quality of Products, save raw material.
Description of the drawings：
Accompanying drawing 1 is the utility model one example structure schematic diagram；
Accompanying drawing 2 is the vacuum part structural representation of Fig. 1 embodiment.
Specific embodiment：
The technique effect of design of the present utility model, concrete structure and generation is made furtherly below with reference to accompanying drawing
Bright, to be fully understood from the purpose of this utility model, feature and effect.
Refering to shown in Fig. 1,2, being preferred embodiment structural representation of the present utility model, the utility model is about a kind of light
Cable extrusion molding Vacuuming structure, includes extruder head 1, and the extruding end of extruder head 1 is provided with die cap 2 and core rod 3, die cap
Plastic passages 4 are left between 2 and core rod 3, and the arrival end of extruder head 1 is assembled with needle tubing 5, and one end of needle tubing 5 extends insertion mould
Core 3, the endoporus of needle tubing 5 is for optical fiber 6 and ointment while pass through, plastic passages 4 of the moulding plastics between die cap 2 and core rod 3 are squeezed
Go out and wrap up optical fiber 6 and ointment, that is, make sleeve pipe 7.The arrival end of the extruder head 1 is provided with vacuum part 8, needle tubing 5 corresponding
End is exposed outside vacuum part 8, and what the vacuum part 8 was connected with vacuum chamber 81 and with vacuum chamber 81 vacuumizes hole 82, and vacuum part 8 is assembled
The space that its vacuum chamber 81 is connected between needle tubing 5 and core rod 3 afterwards, forms vaccum supply system.During use, optical fiber 6 and ointment are simultaneously
Through the endoporus of needle tubing 5, moulding plastics enters plastic passages 4 of the extruder head 1 between die cap 2 and core rod 3 and extrudes and wrap
Optical fiber 6 and ointment is wrapped up in, thus makes sleeve pipe 7.And vacuum part 8 forms a closed space with extruder head 1, core rod 3, so
Can be aspirated from hole 82 is vacuumized with appropriate suction force, the air that the extruding end of extruder head 1 is brought into is from needle tubing 5 and mould
