1. Application of the line
The line is used to extrude loose tube in which 2-12 optical fibers are contained. The extruding material can be PBT,PE.
2. Basic Line Configuration
2.1 12 optical fiber payoff
2.2 Gel filling device and bubble remover device
2.3 Extruder SJ50×30 and head
(With Loader and hopper compound dryer)
2.4 Color Master batch Compounder
2.5 4+4M Hot water trough
2.6 Hot water tank
2.7 E.F.L capstan 800mm
2.8 12 M cooling trough
2.9 Cooling water tank (with refrigerating device)
2.10 Blow dryer device
2.11 Diameter control system
2.12800 Capstan (with tension control device)
2.13Accumulator type tension controller
2.14 Full-automatic double spooler
2.15 Electrical control system
3. Line specification
3.1 Optical fiber pay-off (with release static system)
3.2 Gel filling and bubble remover device
The device is similar with Nextrom's machine
The first-degree gear pump draws gel to sealed can of bubble remover device. The jelly is drawed into sealed through many tiny pinholes, to break the bubble. And vacuum unit draw bubble out of sealed.
The second gear pump driven by a AC servo motor draws gel to filling can from sealed can of bubble remover device.
3.3 Extruder SJ50×30 and one cross head
3.4 Color Master batch Compounder
3.5 4+4M hot trough
3.6 Constant temperature water tank
3.7 Single wheel E.F.L capstan
3.8 8m cooling trough
3.9 Cooling water tank (with refrigerating device)
3.10 Blow dryer device
Adopting HALF structure. easily operate . Special designed for loose tube. with noise rejection device .with a bracket which avoid loose tube shaking. compressed air blew-dry. four blew-dryer
3.11 Diameter control system
3.12 800 Capstan (with tension control device)
3.13 Accumulator type tension controller
3.14 Full-automatic double spooler(with one set of Anti static device )
The take-up is copied to Nestrom.
