Sheet glue film extrusion system based on PLC

The invention discloses a PLC-based sheet plate film extrusion system, which comprises an upper computer and a lower computer, and the upper computer and the lower computer are in communication connection with each other; the upper computer sends an execution signal to the execution device through the lower computer, and the signal fed back by the execution device is transmitted to the upper computer through the lower computer; a control system formed by the upper computer, the lower computer and the execution device is divided into a power supply control system, a host speed regulation system, a host temperature control system and a host runner system; and the power supply control system inputs the distributed and transformed input voltage into the host speed regulation system, the host temperature control system and the host runner system. According to the sheet glue film extrusion system based on the PLC, the combination between hardware and software is completed through the PLC and HMI combined control mo
