Abstract

The present application discloses an automatic overvoltage protection method and system for a heating system of a film wrapping machine, wherein the humidity and temperature in the voltage stabilizer are detected by the temperature and humidity sensor; if the humidity of the voltage stabilizer is greater than a preset upper limit humidity, the drying device is turned on to dry the voltage stabilizer; if the temperature of the voltage stabilizer is greater than a preset upper limit temperature, the cooling device is turned on to cool the voltage stabilizer; the voltage stabilizer converts the power supply voltage provided by the power supply line into the working voltage of the heating system, which can solve the existing problem that the fluctuation of the power supply voltage of the heating system will cause the temperature of the heating system to fluctuate, thereby causing the film to melt or be damaged, and ensures the stability of the power supply voltage of the heating system of the film wrapping machine and the stability of the heating temperature of the heating system, so that the film will not melt or be damaged when the film is heated by the heating system.
