A method for using a cooling device for a hot-fill packaging box of a makeup remover cream with a sterilizing effect, comprising the following steps:

Step 1: Start the heater to heat the water inside the insulated water tank and raise the temperature of the surrounding water to 80℃, then start the water pump, which will transport the 80℃ water to the inside of the 80℃ U-type cooling coil through the outlet pipe. The output end of the 80℃ U-type cooling coil will cool the water to 60℃ through the water delivery component between the 80℃ U-type cooling coil and the 60℃ U-type cooling coil, and then transport it to the inside of the 60℃ U-type cooling coil. The output end of the 60℃ U-type cooling coil will cool the water to 60℃ through the water delivery component between the 60℃ U-type cooling coil and the 40℃ U The water delivery component between the cooling coils cools the water to 40℃ and then delivers it to the inside of the 40℃ U-shaped cooling coil. The output end of the 40℃ U-shaped cooling coil cools the water to 20℃ through the water delivery component between the 40℃ U-shaped cooling coil and the 20℃ U-shaped cooling coil, and then delivers it to the inside of the 20℃ U-shaped cooling coil. The output end of the 20℃ U-shaped cooling coil re-delivers the water to the inside of the insulated water tank through the reflux pipe, thereby forming a stepped cooling belt in the conveying direction of the conveyor belt to cool down the makeup remover hot-filled packaging box.

Step 2: When the water delivery component is in use, hot water is delivered to the input pipe, the input pipe delivers the hot water to the first main pipe, the first main pipe delivers the hot water to the heat dissipation pipe, and the exhaust fan is started at the same time. The exhaust fan makes the air inside the cooling box flow, so that the heat dissipation pipe dissipates heat and cools the hot water to a specified temperature. The heat dissipation pipe delivers water to the second main pipe, the second main pipe delivers water to the output pipe, and the output pipe delivers water at a specified temperature.

Step three: When the temperature sensor detects that the temperature of the input water is higher than the specified temperature, the temperature sensor will send a signal, and the controller will control the corresponding motor to rotate. The output end of the motor drives the bidirectional screw to rotate. Under the action of the thread, the bidirectional screw drives the two screw sleeves away from each other, and the screw sleeves drive the two insulation plates away from each other, thereby increasing the heat dissipation area of the heat pipe, increasing the cooling rate of the water, and making the output temperature of the output pipe reach the specified temperature. When the temperature sensor detects that the temperature of the input water is lower than the specified temperature, the two insulation plates are moved closer to each other, reducing the heat dissipation area of the heat pipe, reducing the cooling rate of the water, and making the output temperature of the output pipe reach the specified temperature.

Compared with the prior art, the present invention has the following beneficial effects:

The present invention forms a stepped temperature zone by sequentially arranging an 80°C U-shaped cooling coil, a 60°C U-shaped cooling coil, a 40°C U-shaped cooling coil and a 20°C U-shaped cooling coil in the direction from the feed port to the discharge port. The stepped temperature zone can be cooled in a stepped manner on the packaging box of the makeup remover cream after hot filling, thereby avoiding a sudden drop in temperature and affecting the quality of the makeup remover cream.

The present invention adopts a cooling method to control the temperature of the 60°C U-shaped cooling coil, the 40°C U-shaped cooling coil and the 20°C U-shaped cooling coil, thereby avoiding the need to set up multiple groups of heating equipment and reducing energy consumption.

The present invention detects the temperature of water input to a 60°C U-shaped cooling coil, a 40°C U-shaped cooling coil and a 20°C U-shaped cooling coil in real time through a temperature sensor, and then controls a motor through a controller, and the motor adjusts the distance between two insulation plates, thereby changing the heat dissipation area of the heat dissipation pipe, thereby achieving control of the water temperature.
