DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 2 The utility model provides a coating temperature control device, including a coating tank 1, a circulating water heating system and a raw material barrel 3. A heat conduction coil 11 is provided at the bottom of the coating tank 1. The circulating water heating system includes a circulating water heating device 21, a first discharge pipe 22 and a first return pipe 23. The feed end of the heat conduction coil 11 is connected to the discharge end of the circulating water heating device through the first discharge pipe 22, the discharge end of the heat conduction coil 11 is connected to the return end of the circulating water heating device through the first return pipe 23, and the discharge end of the raw material barrel 3 is connected to the feed end of the coating tank 1 for transferring the coating in the raw material barrel 3 to the coating tank 1.

[0019] In this embodiment, the circulating water heating device 21 is a mold temperature controller, and the circulating water heated in the mold temperature controller is transported to the heat conducting coil 11 through the first discharge pipe 22. After the heat conducting coil 11 exchanges heat with the coating in the coating tank 1, the temperature of the coating in the coating tank 1 is adjusted and controlled, and then the circulating water after heat exchange returns to the mold temperature controller through the first return pipe 23 for reheating. By arranging the heat conducting coil 11 connected to the mold temperature controller at the bottom of the coating tank 1, the coating contained in the coating tank 1 can be heated based on the circulating hot water in the heat conducting coil 11, that is, the temperature of the coating in the coating tank under low temperature weather conditions can be adjusted, which solves the technical problem in the prior art that the viscosity of the coating is difficult to control due to the reduction of the coating temperature under low temperature conditions, and effectively ensures the quality of the coated product.

[0020] like Figure 1 As shown, a paint circulation barrel 4 is also provided between the coating paint tank 1 and the raw material barrel 3, the feed end of the paint circulation barrel 4 is connected to the discharge end of the raw material barrel 3, the discharge end of the paint circulation barrel 4 is connected to the feed end of the coating paint tank 1, and a heating coil 41 is provided in the paint circulation barrel 4, the feed end of the heating coil 41 is connected to the discharge end of the circulating water heating equipment, and the discharge end of the heating coil 41 is connected to the return end of the circulating water heating equipment.

[0021] In this embodiment, based on the heating coil 41 arranged in the paint circulation barrel 4, the coating paint delivered from the raw material barrel 3 can be preheated, so that the coating paint entering the coating paint tank 1 has a relatively suitable temperature, which is beneficial to the heat exchange efficiency between the heat transfer coil 11 and the coating paint in the coating paint tank 1, and provides an extremely favorable prerequisite for ultimately controlling the temperature and viscosity of the coating paint in the coating paint tank 1.

[0022] It should be noted that, in this embodiment, the feed end of the heating coil 41 is connected to the first discharge pipe 22 through a three-way valve, and the discharge end of the heating coil 41 is connected to the first return pipe 23 through a three-way valve, thereby realizing the circulation of hot water in the heating coil 41.

[0023] like Figure 1 As shown, the paint circulation barrel 4 is further provided with a stirrer 42 for stirring the coating paint contained in the paint circulation barrel 4 .

[0024] In this embodiment, a stirrer 42 is provided in the paint circulation barrel 4 to stir the coating contained in the paint circulation barrel 4, so that the heat exchange between the coating and the heating coil 41 is more uniform and rapid, and the heat exchange efficiency is effectively improved.

[0025] Among them, it also includes a first temperature sensor and a temperature controller. The first temperature sensor is placed in the paint circulation barrel 4 for real-time detection of the temperature of the coating paint in the paint circulation barrel 4, and the thermostat is connected to the first temperature sensor and the circulating water heating equipment respectively; the coating paint tank 1 is provided with a second temperature sensor for real-time detection of the temperature of the coating paint in the coating paint tank 1, and the second temperature sensor is connected to the thermostat.

[0026] In this embodiment, the first temperature sensor detects the temperature of the coating paint in the coating circulation barrel 4 in real time, and the second temperature sensor detects the temperature of the coating paint in the coating tank 1 in real time. The thermostat receives the temperature signals of the first temperature sensor and the second temperature sensor and then adjusts the start and stop of the circulating water heating equipment, thereby realizing the regulation and control of the temperature of the coating paint in the coating tank 1.

[0027] like Figure 1 As shown, the feed end of the heat transfer coil 11 and the discharge end of the heat transfer coil 11 are both connected to a first adjustable valve 5 for adjusting the amount of circulating water in the heat transfer coil 11, and the feed end of the heating coil 41 and the discharge end of the heating coil 41 are both connected to a second adjustable valve 6 for adjusting the amount of circulating water in the heating coil 41.

[0028] In this embodiment, the amount of circulating water in the heat coil 11 is regulated by the first adjustable valve 5. When the temperature of the coating in the coating tank 1 is low, the amount of circulating water in the heat coil 11 can be increased, thereby increasing the heat exchange efficiency between the circulating hot water in the heat coil 11 and the coating in the coating tank 1. When the temperature of the coating in the coating tank 1 is high, the amount of circulating water in the heat coil 11 can be reduced, thereby reducing the heat exchange efficiency between the circulating hot water in the heat coil 11 and the coating in the coating tank 1. Similarly, based on the second adjustable valve 6, the temperature of the coating in the coating circulation barrel 4 can be effectively controlled.

[0029] like Figure 1 As shown, it also includes a paint circulation pipe 7, one end of which is connected to the coating paint tank 1, and the other end of the paint circulation pipe 7 is connected to the paint circulation barrel 4.

[0030] In this embodiment, by providing the paint circulation pipe 7, the circulation of the coating paint in the coating paint tank 1 and the paint circulation barrel 4 is achieved, and the regulation and control of the coating paint temperature is further improved.

[0031] It should be noted that the contents not described in detail in this specification belong to the prior art known to those skilled in the art. The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the present application.
