6.Electric control system:
- Power supply: three-phase five wire system, 380V (± 10%), 50Hz, single-phase control voltage 220V
- The main machine and traction motor of the extruder are domestic brand AC motors controlled by frequency conversion speed regulation system. The latest generation of intelligent electronic display calculus temperature controller is selected as the temperature control instrument, and the temperature control accuracy is ± 2 ℃. The panel is equipped with various instruments, indicators, switches and other necessary components, with complete protection functions such as overload, overheating and overcurrent,
- The low-voltage components of the whole machine adopt top brands, which has the advantages of stable starting, running and stopping of the production line, energy saving and consumption reduction.
- The control box is spliced by high-quality anodized aluminum profile and aluminum die-casting corner parts, with simple and stable appearance and simple operation. A dust filter device is installed in the main control box to prevent the service life of electrical components in the cabinet from being affected by dust.
7. Operation direction: right hand machine. Face to machine, light hand releasing line, right hand receiving.
