1.Usage and scope of application
The PEX pipe produced by this production line is mainly used in water heating supply system, central air conditioner piping system, floor radiation heating system and solar water heating system, etc.
2.Machine composition and characteristics
Production flow chart: raw material pretreatment + additives → mixing → melt-grafted extruding → pipe forming → cross linked → inspection & packing → finished product.
Extruding machine: the single screw extruder uses specialized high efficient screw with high rotating speed, high capacity and strong plastification.
Extruding mould: the special designed die is used because of even discharge and easy adjustment. Disk type sizing device is used because its friction force with pipe surface can be minimum so as to avoid adhesion.
Vacuum setting device: all the parts which may touch water are made by stainless steel.
Tractor: two claw belt type high speed tractor uses stepless frequency speed control to meet the requirement of hauling stability.
Double disk winder: it has tension control and can automatically adjust the winding speed. Also it is fixed with pipe arrangement device.
There are many kinds of electric control system for choice such as PLC auto control system, the production speed will be high and stable. Also the control system will be easy to operate.
