Product Details
1. Introduction
Butterfly-type drop optical cable is a new type of indoor fiber optic cable. It is suitable for indoor and terminal installation places that are often need to be bent. It can be cut according to the distance of the site when wiring, and it can be installed with quick connection connectors and optical fiber cold connectors. There is no need to melt fiber during site construction, which greatly improves engineering construction efficiency.
The structure of the butterfly-type drop optical cable is to place the optical fiber between two parallel reinforcements and then extrude a layer of plastic sheath.
The structure of the self-supporting butterfly-type optical fiber cable is to add a metal hanging wire to the structure of the common butterfly-type optical fiber cable. The structure is as follows:
The significant technical feature of the FTTH butterfly-introduced optical cable is not only to provide greater bandwidth, but also to enhance the network’s transparency of data formats, rates, wavelengths and protocols, relax requirements on environmental conditions and power supply, and simplify maintenance and installation. Therefore, this kind of optical cable has been widely used in optical communication systems and has good development prospects.
The introduction of FTTH butterfly cables requires special production equipment. Our company has many years of experience in research and development and manufacturing of optical fiber and cable production equipment. The FTTH butterfly-introduced optical cable production line provided is suitable for the production of (1-2) core butterfly-introduced optical cables. It can be extruded with PVC, LSZH and other jacket materials. The production line has the characteristics of uniform extrusion outer diameter, smooth appearance, fast production speed, high production efficiency, precise take-up and pay-off tension, and easy operation of the production line. It is a professional production equipment for FTTH butterfly-shaped optical cable.
The whole machine of the production line adopts the control technology combining industrial computer and programmable logic controller, namely (PC + PLC) method to realize the synchronous operation of the whole line and the independent operation of the single machine; the operation of the production line, the setting of the parameters and the display are all passed Industrial control computer to carry out, the production control process such as motor start, stop, signal given, motor speed and other production status acquisition are realized by PLC; data transmission between industrial control computer and PLC through communication port; production operation, alarm display can be realized , Emergency stop of production line and other functions.

Main Components
This equipment is mainly composed of pay-off for steel wires device, pay-off device for optical fiber and FRP reinforcement, points, branching and parallel device, extruder unit, cooling system (4m warm water tank, warm water tank, 12m cold water tank, refrigerator), blow dry device and biaxial laser diameter gauge, wheel capstan device, accumulator type tension control device, wiring device and electric control system, etc.
1. Pay-off for Steel Wires
This unit adopts cantilever structure, active pay-off, driven by AC motor, suitable for PN630 and PN800 bobbin and it can meets the pay-off process of steel wires with 0.5～1.2mm diameter. The synchronous operation of pay-off and capstan is controlled by a tension dancer. The pay-off tension of the steel wire can be adjusted within the range of (5～30) N, and the tension control precision is high. The lifting of the reel is driven by the AC reduction motor, and the reel is clamped by the air cylinder. The steel wire pay-off device of this structural form can ensure the stable and reliable operation of the steel wire high-speed pay-off.
The outlet of the wire pay-off device is equipped with a set of wire straightening device, which can straighten the bent and deformed wire to ensure that the wire is straight before entering the extrusion unit, which is beneficial to product processing and production.
2. Pay-off Device for Optic Fiber and FRP Reinforcement Core
The optical fiber and FRP reinforced core pay-off device adopts a cabinet structure, including two fiber pay-off reels and two FRP pay-off reels, which can meet the pay-off of up to two core optical fibers and two FRP. It is suitable for 25km and 50km international common optical fiber reels and PN400 FRP pay-off reels.
The device uses an active pay-off method and is driven by an AC motor. The tension dancer controls the synchronous operation of pay-off and traction. The tension of the optical fiber pay-off can be adjusted within the range of (0.4 ～ 1.5) N, and the tension of the FRP pay-off can be adjusted within the range of (1.0 ～ 10) N with high tension control accuracy and constant and reliable pay-off tension.
3. Extruder Unit
Adopting SJ65×25 type extruder, BM type screw, this extruder unit is suitable for the extrusion of PVC, LSZH and other materials with stable and uniform extrusion amount and high control accuracy and reliability.
The extruder head is equipped with pressure protection device, which has an alarm function when the extrusion pressure is too high. At the same time, the extrusion unit is equipped with a vacuum feeder and a dryer.
4. Accumulator Type Tension Controller
The device adopts horizontal horizontal structure and is arranged above the water tank of the production line. This arrangement can reduce the total length of the production line and save floor space.
The take-up tension can be adjusted within the range of (3 ～ 20) N. The maximum accumulator length can reach 100m, which reserves operation time for double-bobbin switching.
5. Take-up and Traverse Device
The device adopts double-bobbin manual switching type and cantilever structure. This device has a compact structure and occupies a small area. It is suitable for PN630 and PN800 bobbin. The AC servo motor controls the traversing arrangement. The pitch of the cable is high in precision and continuously adjustable. The tailstock bobbin loading method is simple and easy to operate.
