Description

Technical Field

[0001] The utility model relates to a drying device, in particular to a drying device for coated lunch boxes. Background Art

[0002] During the drying process of coated lunch boxes, the temperature needs to be controlled within a certain range to ensure that the coating can be cured evenly and completely. In addition to temperature, the drying time is also a key factor determining the quality of the coating. The drying time needs to be long enough to ensure that the solvent or moisture in the coating can evaporate sufficiently, and at the same time, it cannot be too long to avoid energy waste and low production efficiency.

[0003] The existing drying devices for coated lunch boxes have low drying efficiency and cannot be adjusted in real time according to the temperature distribution. Low efficiency will cause more energy consumption, and the humidity and air flow in the drying chamber also affect the drying effect of the coating.

[0004] To solve the above problems, a series of improvements have been made. Summary of the Utility Model

[0007] Among them, the drying mechanism includes: an outer box body, an inner container, a air supply duct, a directional guide plate, an adjustable fan, a heating component, a humidity sensor, and an air velocity sensor. The inner container is internally connected to the outer box body. The air supply duct is connected to the outer box body. The directional guide plate is internally connected to the air supply duct. The adjustable fan is connected to the inlet end of the air supply duct. The heating component is externally connected to the inner container. The humidity sensor and the air velocity sensor are connected to the inner wall of the outer box body.

[0008] Further, the conveying mechanism includes: a conveyor belt, a driving motor, a guide rail, a turning belt, and a pushing plate. The conveyor belt is internally connected to the drying mechanism, the conveyor belt is connected to the guide rail, the guide rail is connected to the base, the driving motor is connected to the guide rail, the turning belt is connected to the end of the conveyor belt, and the pushing plate is connected to the side of the guide rail.

[0009] Advantages of the Utility Model

[0010] Compared with traditional technologies, the present utility model can improve the distribution of heating airflows and enhance the drying efficiency by adding a new drying mechanism with a directional air duct and an adjustable fan.

[0022] As Figure 1As shown in the figure, a drying device for a coated lunch box includes: a base 100, a drying mechanism 200, a control system 300, a conveying mechanism 400, and an infrared thermal imager 500. The drying mechanism 200 is connected to the upper part of the base 100. The control system 300 is arranged on the base 100. The control system 300 is connected to the drying mechanism 200, the conveying mechanism 400, and the infrared thermal imager 500. The conveying mechanism 400 is arranged on the base 100. The conveying mechanism 400 is connected to the inside of the drying mechanism 200. The infrared thermal imager 500 is connected to the outside of the drying mechanism 200;

[0023] As Figure 4 shown, among which, the drying mechanism 200 includes: an outer box body 210, an inner container 220, a air supply duct 230, a directional deflector 240, an adjustable fan 250, a heating element 260, a humidity sensor 270, and an air velocity sensor 280. The inner container 220 is connected to the inside of the outer box body 210. The air supply duct 230 is connected to the outer box body 210. The directional deflector 240 is connected to the inside of the air supply duct 230. The adjustable fan 250 is connected to the inlet end of the air supply duct 230. The heating element 260 is connected to the outside of the inner container 220. The humidity sensor 270 and the air velocity sensor 280 are connected to the inner wall of the outer box body 210.

[0024] As Figure 2 and Figure 3 shown, the conveying mechanism 400 includes: a conveyor belt 410, a driving motor 420, a guide rail 430, a turning belt 440, and a pusher plate 450. The conveyor belt 410 is connected to the inside of the drying mechanism 200. The conveyor belt 410 is connected to the guide rail 430. The guide rail 430 is connected to the base 100. The driving motor 420 is connected to the guide rail 430. The turning belt 440 is connected to the end of the conveyor belt 410. The pusher plate 450 is connected to the side of the guide rail 430.

[0025] The principle of this utility model is as follows. First, the control system 300 starts the entire device, and the drive motor 420 begins to operate. The pusher plate 450 pushes the coated lunch boxes onto the guide rail 430, and the guide rail 430 sends the coated lunch boxes into the conveyor belt and then into the drying mechanism 200 as the conveyor belt moves. When the lunch boxes enter the drying mechanism 200, the adjustable fan 250 starts to work, sucking in external air into the air supply duct 230. The heating element 260 is simultaneously activated to heat the air to the required temperature. The design of the directional deflector 240 ensures that the hot air flows towards the coated lunch boxes at an appropriate angle and speed, achieving uniform drying. The humidity sensor 270 and the air flow rate sensor 280 continuously monitor the humidity and air flow rate inside the drying chamber. The control system 300 adjusts the speed of the adjustable fan 250 and the power of the heating element 260 based on this data to maintain the optimal drying environment. The infrared thermal imager 500 is installed outside the drying mechanism 200 to non-contact detect the surface temperature distribution of the coated lunch boxes. This helps ensure that all parts of the lunch boxes are properly dried, avoiding overheating or uneven drying. When the coated lunch boxes are dried, they continue to move along with the conveyor belt 410 and are discharged from the drying mechanism 200 through the turning belt 440, ready for the next step of packaging or storage. By adding a new drying mechanism, this utility model can improve the distribution of the heating air flow by using the directional air duct and the adjustable fan, enhance the drying efficiency, and install an infrared thermal imager to ensure the uniform temperature distribution in the drying room and timely adjust the output of the heating element to reduce the problem of uneven drying.

[0026] The specific embodiments of the present utility model have been described above, but the present utility model is not limited thereto. As long as it does not depart from the purpose of the present utility model, the present utility model can have various variations.
