Abstract
The invention discloses high-speed optical cable sleeve pipe production equipment and belongs to the technical field of communication device production equipment. The high-speed optical cable sleeve pipe production equipment is characterized in that cooling water is contained in a rectangular cold water box, an extra-length setting wheel branching wheel and an extra-length setting wheel main driving wheel are arranged front and back in the cold water box, parts of the extra-length setting wheel branching wheel and the extra-length setting wheel main driving wheel are immersed in cooling water, and a cold water sprayer is arranged at the top of the cold water tank and is communicated with an external cold water pipe. The high-speed optical cable sleeve pipe production equipment has the advantages that the optical fiber extra-length of sleeve pipe products produced by the production equipment is effectively controlled, sleeve pipe extra-length increasing caused by PBT material secondary crystallization is removed, and product quality is improved; after a sleeve pipe enters a hot water groove at the best crystallization temperature and product hardness is increased, a cold water groove is removed, so that a whole set of production route is shortened by 8-12 m, accordingly, production speed is increased, production efficiency is improved, and sleeve pipe production linear speed reaches at least 400 m/min for the first time; and space is saved, and compared with traditional production equipment, at least the field space of 8-12 m is saved.
Description
Technical field
The invention belongs to Communication Equipment production equipment technical field.
Background technology
Tradition both at home and abroad cable sleeve production equipment primarily of extruder head, hot water storgae, boiler, be arranged in boiler more than long traction wheel, cold rinse bank, the parts composition such as main traction and take-up reel.
At present both at home and abroad ferrule production technology all accessed after hot water storgae after extrusion head is extruded in boiler by optical fiber more than long traction wheel produce needed for ferrule technology controlling and process remaining long after be wrapped on take-up reel shaping after cold rinse bank and main traction.
Its deficiency is: 1, current existing sleeve pipe production equipment is the production cooling being carried out ferrule by the cooling devices such as hot water storgae+boiler+remaining long traction wheel+main traction+cold rinse bank and facility, will affect the speed of production of ferrule because the path be made up of the said equipment is longer.2, existing equipment total length is longer, larger by place restriction.
Summary of the invention
The object of the invention is: provide a kind of high speed cable sleeve production equipment, owing to cutting cold rinse bank, the equipment total length of making shortens greatly.
Technical scheme of the present invention is: be made up of extruder head (1), hot water storgae (2), boiler (3), main traction (4), cold water storage cistern (5) and automatic takeup system (6).
Chilled water has been taken up in rectangle cold water storage cistern, remaining long shaping wheel branching wheel and remaining long shaping wheel main drive wheel is separately installed with before and after in cold water storage cistern, remaining long shaping wheel branching wheel and remaining long shaping wheel main drive wheel part are immersed in chilled water, be provided with cold water sprays device and be communicated with outer cold water pipe at cold water storage cistern top.
The invention has the beneficial effects as follows: in cold water storage cistern, remaining long traction wheel is formed by driving main wheel and passive branching wheel, and a whole set of production equipment does not have cold rinse bank.
Adopt to improve boiler water temperature and in boiler, increase high precision water admixing device and control water temperature precision, make the crystallinity of sleeve pipe get a promotion (crystallization of sleeve pipe when 50 ~ 60 degree temperature is optimum condition) while can improve speed of production.
1, the excess fiber length of production equipment production casing product is effectively controlled thus, and eliminates PBT and expect that the sleeve pipe that causes of secondary crystallization is remaining and longly to increase, and improves the quality of products.
2, sleeve pipe is after best Tc enters hot water storgae increase product hardness, is being removed by cold rinse bank, and make a whole set of generation produce path shortening 8 ~ 12 meters, thus speed of production is promoted, production efficiency increases, and makes sleeve pipe produce linear speed and arrives more than 400m/min first.
3, conserve space, compares 8 ~ 12m production space, the minimum saving place of conventional production equipment.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1,1 be molding machine head, 2 are hot water storgaes, 3 are boilers, 4 are main tractions, 5 are cold water storage cisterns, 6 is automatic takeup systems.
As shown in Figure 2-5,5-1 is remaining long shaping wheel main drive wheel, 5-2 is cold water sprays device, 5-3 is remaining long shaping wheel branching wheel, 5-4 is cold water storage cistern housing, 5-5 is chilled water, 5-6 is outer cold water pipe.
Optical fiber enters extruder head (1) and is squeezed into after PBT beam tube through hot water storgae (2) and boiler (3) cooling forming, drawn after pitch of the laps by main traction wheel (4) again and enter cold water storage cistern (5), through cooled optical fiber bundle tubes under the drive of automatic takeup system (6) take-up on take-up reel.
Its principle of work is:
1. optical fiber is squeezed into the macromolecule plastic casings such as PBT after extrusion head 1.
2. the macromolecular material sleeve pipe such as PBT is wound around in main traction through hot water storgae cooling and shaping with after boiler, produces the primary design that process for producing casing produces remaining long.(install automatic water mixing device in boiler, control hot water temperature's difference between ± 1 DEG C, PBT overlaps materials in the tube makes the crystallization of the materials such as PBT arrive best Theoretical Design value in direct access hot water after extrusion head is extruded, thus improves the line speed of product)
3. cable sleeve enters in cold water storage cistern and carries out secondary sizing long more than sleeve pipe after main traction is wound around, thus reaches the remaining long Theoretical Design value of sleeve pipe inner fiber, guarantees that the mechanical property of optical cable and environment temperature performance index meet standard-required.(arrange remaining long traction wheel in cold water storage cistern to grow by driving main wheel and passive branching wheel forms to produce more than Stability Design, in cold water storage cistern, chilled water carries out spray by 9 spraying cocks and completes)
4. the sleeve pipe that cold water storage cistern has been shaped is wrapped on sleeve pipe take-up reel through the automatic takeup system of fixing tension force.(fixing bush automatic takeup system is by counteracting or to avoid the macromolecule shell material secondary crystallizations such as PBT to produce more than unnecessary sleeve pipe long).
Claims (1)
1. a high speed cable sleeve production equipment, it is characterized in that: in rectangle cold water storage cistern, taken up chilled water, remaining long shaping wheel branching wheel and remaining long shaping wheel main drive wheel is separately installed with before and after in cold water storage cistern, remaining long shaping wheel branching wheel and remaining long shaping wheel main drive wheel part are immersed in chilled water, be provided with cold water sprays device and be communicated with outer cold water pipe at cold water storage cistern top.
