The discharge end adopts the same method, and an air guide pipe 20 is connected between the airflow insulation air outlet hood 2, so that the heat loss at the feeding and discharging parts can be reduced. A lower mounting box seat 15 is provided below the main body 1 of the vulcanization tunnel furnace, and a conveying mechanism 19 is installed in the lower mounting box seat 15. A temperature sensor 16 is installed on the inner side of the lower mounting box seat 15 above the conveying mechanism 19, and the temperature sensor 16 corresponds to the preheating section 4, the heating section 7 and the cooling section 10 respectively. This structure temperature sensor 16 adopts thermal The thermocouple sensor or thermistor sensor is used to measure the temperature in the vulcanization tunnel furnace body 1 in real time, so as to control the temperature in each section of the furnace body as needed. A temperature controller 21 is installed on the outer side of the lower mounting box seat 15, and the temperature controller 21 is connected to the temperature sensor 16 signal, and the temperature controller 21 is respectively electrically connected to the first resistance heater 14, the second resistance heater 8, the cooling air duct 9 and the driver of the air guide duct 20. The signal of the temperature sensor 16 of this structure can be input into the temperature controller 21, and the temperature controller 21 can process and analyze the temperature data based on the microprocessor or PLC, so as to better control the temperature in the vulcanization tunnel furnace body 1 in real time. The first resistance heater 14 and the second resistance heater 8 are respectively installed in the preheating section 4 and the heating section 7. The second resistance heater 8 is provided, and a partition support seat 5 is provided between the heating section 7 and the preheating section 4 and the cooling section 10, respectively. A rotating shaft 6 is respectively passed through and fixed in the partition support seat 5, and an air flow mixing fan 17 is installed at the lower end of the rotating shaft 6. When this structure controls the temperature in the vulcanization tunnel furnace body 1, when the vulcanization tunnel furnace body 1 is started, the first resistance heater 14 and the second resistance heater 8 are turned on at the same time, so that the preheating section 4 and the heating section 7 are heated to the required temperature respectively. After the temperature in the preheating section 4 and the heating section 7 is stable, the first resistance heater 14 can be turned off, and the air flow mixing fan 17 in the partition support seat 5 between the preheating section 4 and the heating section 7 is started to mix the temperature between the preheating section 4 and the heating section 7, thereby ensuring the preheating temperature and reducing the resistance.At the same time, when the vulcanization tunnel furnace body 1 is cooled as a whole, the airflow mixing fan 17 in the partition support seat 5 between the heating section 7 and the cooling section 10 is started to mix the hot and cold airflows to achieve the purpose of cooling and better energy saving.

The airflow mixing fan 17 rotates under the drive of the motor through the rotating shaft 6 to mix the airflow between the preheating section 4 and the heating section 7, so that the temperature in the preheating section 4 is always maintained, and the vulcanization is performed. When the vulcanization tunnel furnace body 1 is working, the door panel lifting mechanism 13 in the feed hood 3 drives the feed and discharge control door panel 12 to rise, and at the same time, the air guide pipe 20 is started under the drive of the motor, so that the airflow insulation outlet hood 2 sprays airflow to form an airflow partition wall to prevent heat loss.
