Improved Temperature Control System Research of Sound Insulation Cotton Heat Sealing Machine

摘要

In order to do large scale line length heat-sealing for the sound insulation cotton and resistance to flame clad-ding layer materials of new aircraft, the system has been improved according to the original heat sealing ma-chine temperature control system. It uses thermocouple sensor of high response to collect the temperature signal. And it also controls the output power of pulse digital DC power supply by S7-200 PLC based on the principle of PWM. Therefore, it meets the requirements of temperature control. Eventually, the temperature control system can ensure heat sealing requirements of the new type materials after test research.
