Three-layer co-extrusion top-spinning cold blown film production line
- Description
- The three-layer co-extruded energy-saving blown film production line consists of three single-screw extruder auxiliary machines.1. The host adopts Zhejiang Golden Conch.2. The die adopts the spiral die of the international advanced new flow channel technology.3. The main machine is heated by cast aluminum; the die is heated by high temperature ceramic strip heater…4. The upper traction rotating device adopts a direct transmission type horizontal ±360° reciprocating rotation.5. The internal cooling system (IBC) automatically measures and controls the bubble size using a 3-point over-sound probe.6. Configure the electric squirrel cage stabilization bubble holder.7. Configure the ultrasonic automatic correcting device.8. Automatic friction full tension control control sensor, control traction tracking receiving and unloading system.9. The control system adopts Japanese Mitsubishi PLC centralized control technology.
