Controlling system:
The system adopts impotred PLC+ feel-type operating dispay. It can realize full control and management for action, picture etc. and can also do high reliability. multiple-functions and intellectualization of system.
The system can mainlu realize the following functions;
1. Real time controlling actions of the machine
2. 64 points parison axail wall thickness control
3.Opening/closing mould control speed and curve control.
4.Auto-alarming under the conditions of overtime and not reaching the correct position.
5. General-purpose muliiple-functions system
6. Real time displaying the current working conditions
7. Real tine displaying the trouble and alarming information.
8.The system is automatically reset before the circular action begins
9.Manually set the varied conditions to ensure safety
10. The data is directly modified on the screen.
The temperature controlling systemn employs imported automatic temperature controller, which can relize automatically controlling temperature of 11 points, DC motor speed regulator of the extruder adopts imported digital DC speed regulator,which ensures stabke and reliable running of extruder.
