◆Using Siemens PLC and touch screen, the feeding is accurate and stable, the operation is convenient, the equipment runs stably and is easy to control.
◆It adopts Siemens PLC and touch screen for control to ensure the reliability of continuous operation of equipment, low comprehensive operation cost, low failure rate, simple structure, convenient and quick management and maintenance, uniform feeding, safe and convenient operation, and use together with mixer to achieve no Humanized mixing feed to achieve automated production of extruded panels
PLC control system overview
The main interface includes feeder system control, No. 1 screw and No. 2 screw control system, fan cooling system, injection system control, and temperature control system. Among them, the feeder system: according to the demand of the plate, different feeding amount can be set, the minimum 100KG, the maximum 2000kg, depending on the actual production. The startup of the host is to start the No. 2 machine and then start the No. 1 machine. The fan system acts as a cooling device in the No. 1 and No. 2 machines. There are two ways to give carbon dioxide and accelerators. One is to directly pass the frequency. In addition, the flow can be set directly, and the fixed flow can be directly set. The system will automatically stabilize to the set flow, and the conversion mode is through the flow setting. The setting and frequency setting buttons are switched, the flow screen of the dioxin foaming agent and the accelerator is displayed on the touch screen, the pressure and temperature of the static mixing of the No. 2 screw are displayed, and the date and time are displayed. The temperature function (optional) for setting and displaying the No. 1 and No. 2 units is also integrated on the touch screen. The frequency setting range is 0-50 Hz throughout the system. It also includes start and stop control of the pump and constant pressure pump.
