LJD/500 Wire Drawing Isolation Line

LJD/500 Wire Drawing Isolation Line

MJXD-LJD/500 single wire drawing line mainly consists of wire drawing machine, diameter measuring instrument, extruder, cooling tank and take-up disc. This cable insulation machine is used for continuous production of insulated single core wires for high-quality digital communication cables, network cables and data cables.

1.LJD/500 single wire drawing line can realize one-time drawing, annealing, preheating and extrusion continuously. It possesses high production speed and good core wire performance.
2.This cable insulation machine adopts high-precision on-line laser diameter measuring instrument that can measure diameter precisely and also control the quantity of glue from extruder. This wire drawing line owns good synchronization performance and high sensitivity. It can accurately control the core wire diameter.
3.The insulated single wire drawing line uses fully automatic double disc to take up cables reliably and accurately. We can change discs in high speed. The success rate of changing disc reaches over 99%.
4.This cable insulation machine adopts PLC online whole-process control with good synchronization performance and stable performance.
5.The cable take-up tension can be initiatively adjusted so that the tension is constant and reliable.
6.This single wire drawing line is easy to operate with low noise and high efficiency.

1. The entire cable insulation machine is made ​​with overall optimal adjustment and transformation based on the original old technology. The overall technological level is in the domestic leading position in the cable industry.
2. Drawing-annealing-preheating all-in-one machine optimizes the composite structure, reduces the volume, enhances the appearance, reduces the area, facilitates the operation and improves the work efficiency. It also optimizes the transmission structure of this single wire drawing line. We adopt all-belt drive, avoiding slip jumping wire phenomenon in the drawing process and improving the stability and reliability of equipment operation.
3. Self-circulation cooling system of this cable insulation machine ensures the temperature stability requirements for plastic insulating layer during the cooling shrinkage process. Thus it ensures the plasticized quality and effect of the plastic insulation layer.
4. Double-disc take-up, automatically changing disc and automatic disc take-up room optimize the single-wire tension adjuster so that the tension of the single wire drawing line can be adjusted freely. We also transform the flutter line structure and enhance the reliability and stability of changing disc. Double top disc device adopts our self-developed large three-claw with high friction and high jacking force. Whenever the disc is empty or full disc, it rotates at high speed without shaking and beating. There is also a new top plate mechanical structure device that is to declare the patent.
