When the temperature in the inside of the box body 1 is higher than the set temperature, the control unit controls the temperature and humidity adjusting unit to cool. When the temperature in the inside of the box body 1 is lower than the set temperature, the control unit controls the temperature and humidity adjusting unit to heat. When the humidity in the inside of the box body 1 is lower than the set value, the control unit controls the temperature and humidity adjusting unit to humidify. When the humidity in the inside of the box body 1 is higher than the set value, the control unit controls the temperature and humidity adjusting unit to accelerate the flow of gas to reduce the humidity. When the temperature and humidity adjusting unit cools, heats and / or humidifies, the air enters the inside of the box body 1 through the air inlet 20 and is discharged through the air outlet 21, so that the inside of the box body 1 keeps constant temperature and humidity.

[0025] It can be understood that the temperature of the temperature recovery can be a certain temperature value or a certain temperature range, and the humidity of the temperature recovery can be a certain humidity value or a certain humidity range.

In the preset time, the timing power switch 3 provides power for the electric control lock 101 and the constant temperature and humidity device 2. The electric control lock 101 is in the power-on state, so that the box door 10 cannot be opened at will. The constant temperature and humidity device 2 adjusts the temperature and humidity in the inside of the box body 1, so that the inside of the box body 1 keeps constant temperature and humidity. After the preset time, the timing power switch 3 is powered off, the box door 10 can be opened, the constant temperature and humidity device 2 is powered off and does not work, and the temperature recovery is finished.

[0028] The embodiment is provided with a constant temperature and humidity device on the box body of the warming box and an electric control lock on the box door. The constant temperature and humidity device and the electric control lock are controlled through a timing power switch.

During the warming process, the rubber cakes are laid flat in the box body 1. When the constant temperature and humidity device 2 works, air is taken in through the air inlet 20 and taken out through the air outlet 21, so that the temperature and humidity in the box body 1 are uniform and stable. Further, a baffle (not shown in the figure) is arranged at a position between the air inlet 20 and the air outlet 21 inside the box body 1. The height of the baffle is less than the height of the box body 1. Optionally, the height of the baffle is half of the height of the box body 1. After the baffle is arranged, when the constant temperature and humidity device 2 works, the air path in the box body 1 is in a U-shaped circulation from the air inlet 20 to the air outlet 21. Fresh air will not directly blow to the surface of the rubber cakes, further making the temperature and humidity in the box body 1 uniform and stable, so that the warming conditions of all the rubber cakes to be warmed are consistent, the warming speed is consistent, and the product quality is improved.

The temperature and humidity sensing assembly 23 is arranged in the box body 1 and comprises a temperature sensor and a humidity sensor, and is used for sensing the real-time temperature and humidity in the box body 1. The temperature regulator comprises a heater and a refrigerating device, and it can be understood that the temperature regulator and the humidity regulator both comprise a fan and other air inlet and outlet devices. The control mainboard can preset the temperature and humidity required for rewarming, and the control mainboard triggers the temperature regulator and / or the humidity regulator according to the preset temperature and humidity and the real-time temperature and humidity data, so as to adjust the temperature and humidity in the box body, so that the EMC cake is rewarming under the condition of constant temperature and humidity. It can be understood that the rewarming time can be preset in the control mainboard, and the electric control lock 101 is electrically connected with the control mainboard, and when the rewarming time is reached, the control mainboard sends a signal to the electric control lock 101, so that the box door 10 can be opened.
