[0020] Please see Figure 1 A preferred embodiment of this utility model provides a liquid nitrogen cooling mechanism for blow molding edge material, including a cooling component 1, a conveyor belt 2, a cooling chamber 3, a controller 4, and a drive component. The conveyor belt 2 transports the blow molding edge material to be cooled into the cooling chamber 3. The cooling component 1 cools and lowers the temperature of the blow molding edge material in the cooling chamber 3. The controller 4 is used to adjust the cooling temperature of the blow molding edge material to be cooled by the cooling component 1. The drive component is used to drive the conveyor belt 2 so that the conveyor belt 2 can automatically transport the blow molding edge material to be cooled into the cooling chamber 3.

[0021] Specifically, the cooling assembly 1 includes a liquid nitrogen storage tank 11, a conveying pipe 12, and a nozzle. The two ends of the conveying pipe 12 are connected to the liquid nitrogen storage tank 11 and the nozzle, respectively. The nozzle is located inside the cooling chamber 3 and faces the conveyor belt 2. The cooling assembly 1 is placed next to the conveyor belt 2. The liquid nitrogen storage tank 11 contains liquid nitrogen, which is conveyed to the nozzle through the conveying pipe 12. The nozzle is aimed at the conveyor belt 2 inside the cooling chamber 3. The blow molding edge material to be cooled is placed on the conveyor belt 2 and conveyed into the cooling chamber 3. The nozzle is activated to atomize the liquid nitrogen and spray it evenly onto the blow molding edge material. Using liquid nitrogen cooling can greatly shorten the cooling time of the blow molding edge material and improve production efficiency. In addition, the ultra-low temperature of liquid nitrogen can quickly solidify the blow molding edge material, reduce deformation and internal stress, and improve material performance. Furthermore, liquid nitrogen is an inert gas and will not chemically react with the blow molding edge material. Moreover, there is no residue after vaporization, making it environmentally friendly and pollution-free.

[0022] In this embodiment, a temperature sensor is installed inside the cooling chamber 3. The temperature sensor can detect the temperature of the cooling chamber 3 so as to control the cooling temperature. The temperature sensor is located near the surface of the conveyor belt 2. The cooling chamber 3 is not a completely closed environment, and the temperature in different parts of the chamber is not completely the same. The closer the temperature sensor is to the conveyor belt 2, the more accurate the temperature measurement of the conveyor belt 2 will be.

[0023] Furthermore, several temperature sensors are provided, arranged along the conveying direction of the conveyor belt 2, to monitor the temperature change of the blow molding edge material to be tested throughout the entire process from the input cooling chamber 3 to the output cooling chamber 3, which further facilitates the control of the cooling temperature.

[0024] The output of the temperature sensor is electrically connected to the input of the controller 4. A regulating valve is installed on the delivery pipe 12, and the output of the controller 4 is electrically connected to the input of the regulating valve. To achieve the ideal cooling effect, blow-molded edge materials of different materials and thicknesses require different cooling temperatures. During the cooling process, the temperature sensor monitors and reports the surface temperature of the blow-molded edge material to be cooled in real time, and feeds the data back to the controller 4. The controller 4 controls the regulating valve to adjust the spray volume and frequency of liquid nitrogen according to the set target temperature, ensuring that the blow-molded edge material is cooled quickly and evenly.

[0025] Support plates 21 are provided on both sides of the conveyor belt 2, and the controller 4 is installed on the support plates 21. The controller 4 is located in an easily accessible position for convenient future maintenance.

[0026] The cooling chamber 3 has an inlet 31 and an outlet 32. The conveyor belt 2 enters from the inlet 31 and exits from the outlet 32. Air curtain machines 33 are installed at both the inlet 31 and the outlet 32. The air supply direction of the air curtain machines 33 is perpendicular to the conveying direction of the conveyor belt 2. The air curtain machines 33 can generate high-speed airflow, forming an invisible barrier at the inlet 31 and the outlet 32. This airflow barrier can effectively isolate the heat exchange between the inside and outside of the cooling chamber 3, keeping it in an ideal low temperature state.

[0027] A preferred embodiment of this utility model also provides a blow molding processing apparatus, including a conveying mechanism, a feeding mechanism, and a liquid nitrogen cooling mechanism for blow molding edge material as described in the above embodiment. The conveying mechanism is located at the input end of the conveyor belt 2 and is used to convey the blow molding edge material to be cooled to the conveyor belt 2. After the edge material is produced by blow molding, it is placed on the conveyor belt 2 by the conveying mechanism and cooled by liquid nitrogen in the cooling chamber 3, which greatly shortens the cooling time of the blow molding edge material and improves production efficiency. In addition, the ultra-low temperature of liquid nitrogen can quickly solidify the blow molding edge material, reduce deformation and internal stress, and improve material performance. Furthermore, liquid nitrogen is an inert gas and will not chemically react with the blow molding edge material, and leaves no residue after vaporization, making it environmentally friendly and pollution-free. The cooled blow molding edge material is then conveyed by the conveyor belt 2 to the feeding mechanism, which then conveys it to the next station for further processing.

[0028] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
