The plastic filament drawing machine uses polypropylene, polyethylene, PET, PBT, nylon, etc. as raw materials, and is heated, extruded and stretched to form filaments of different shapes, which are for subsequent processing. Filament drawing machines have generally been improved many times, and can be drawn into round wire, triangle wire, etc. from 100% recycled materials or granular materials. The screw and barrel of the plastic fiber extruding machine are made of 38CrMoAlA alloy steel, and the hardness is above Hv950 after nitriding treatment. The standard reached is that the extruder adopts a hard gear reducer made of 20CrMnTi alloy steel, the sprocket is made of 45# medium carbon steel after high-frequency quenching, the traction roller is electroplated with hard chromium, and the traction mechanism increases the self-control tension rewinding roller. The discharge barrel, tee and film head are heated by cast aluminum heating ring to achieve the purpose of durability. The plastic filament extruding machines on the market are all non-drying exhaust energy-saving plastic wire drawing machines. Its main feature is that there is an exhaust port on the barrel, and the barrel has at least two sections connected. The screw in the first section of the barrel The screw pitch is different from the later ones. It does not need to be stirred, and can absorb the water generated by the plastic during the stirring. The drawn plastic wire has a uniform thickness and smoothness, is not easy to break, and has high working efficiency and low energy consumption. The energy saving of plastic wire drawing machine can be divided into two parts: one is the power part and the other is the heating part. Energy saving in the power part: Most of the inverters are used. The energy saving method is to save the residual energy of the motor. For example, the actual power of the motor is 50Hz, and you actually only need 30Hz in the production to be enough for production, and the excess energy consumption is in vain If it is wasted, the inverter is to change the power output of the motor to achieve energy saving effect.
