Temperature detection alarm system for vulcanizing machine

The utility model relates to a temperature detection alarm system for a vulcanizing machine. The vulcanizing machine comprises a vulcanizing machine body, heater arranged in vulcanizing machine, a temperature sensor for forming a temperature detection signal is arranged in the vulcanizing machine body; the temperature sensor is coupled with a low-temperature control circuit which is used for presetting a low-temperature reference value, receiving the temperature detection signal and outputting a low-temperature control signal; the temperature sensor is coupled with a preset high-temperature reference value, receives the temperature detection signal and outputs a high-temperature control signal; the low-temperature control circuit is coupled with a time delay circuit for receiving the low-temperature control signal and outputting a time delay signal; the time delay circuit is coupled with an alarm circuit for receiving the time delay signal and outputting an alarm signal, the alarm circuit starts to alarm and
