Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically a graphene nano-heating and baking device. Background Technology

[0002] Currently, most painted parts on the market are baked in ordinary ovens, which leads to unstable baking temperatures and increases the scrap rate of painted parts. At the same time, ordinary heating processes increase energy consumption and costs. However, the graphene nano-heating oven for baking paint not only has stable temperature, but also maintains a stable and uniform baking temperature on the surface of the workpiece, which greatly improves the product baking qualification rate and saves energy.

[0003] However, in actual use, the graphene heating plate of the aforementioned graphene nano-heating oven cannot adhere to the painted workpiece. Adhesion would affect the uniformity and smoothness of the paint layer on the workpiece surface, and heat still needs to be conducted through air. Hot air has the characteristic of low density and rising. During long-term baking, the temperature at the top of the oven is higher than that at the bottom, and the painted parts will still experience uneven heating. The upper part may be over-baked, while the lower part is under-heated, resulting in uneven curing of the paint film. In view of this, we propose a graphene nano-heating baking device. Utility Model Content

[0004] The purpose of this invention is to provide a graphene nano-heating and baking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a graphene nano-heating and baking device, including an oven, a door hinged to the front of the oven, and a heating component disposed inside the oven, the heating component including:

[0006] An inner cavity partition is provided, with a graphene heating plate fixedly connected to the inner wall of the partition. A sliding rod is slidably connected to the top end face of the partition, and a hook is fixedly connected to the bottom end face of the sliding rod. A through groove is provided on the side wall of the partition, and an air outlet is provided on the bottom end face of the partition.

[0007] A partition, wherein a return air vent is provided at the bottom of the partition and an air inlet is provided at the top of the partition;

[0008] An electric motor, wherein a rotating shaft is fixedly connected to the output end of the motor, and a fan is fixedly connected to the side wall of the rotating shaft.

[0009] Preferably, the inner cavity partition is shaped like a shuttle, and the through groove is opened on the side of the inner cavity partition away from the air outlet. The shuttle-shaped inner cavity partition allows the airflow to flow along the outer wall of the inner cavity partition, thereby making the outer wall temperature of the inner cavity partition uniform.

[0010] Preferably, the partition and the inner wall of the oven are provided with a return air cavity, which connects the return air inlet and the air inlet. The airflow is blown downward by the fan, enters the return air cavity through the return air inlet, and then re-contacts the outer wall of the inner cavity partition through the air inlet to achieve airflow circulation.

[0011] Preferably, the motor is fixedly connected to the top end face of the oven, and the fan is positioned directly above the inner cavity partition.

[0012] Preferably, a handle is fixedly connected to the bottom end face of the slide rod, and the handle is located on the side of the bottom of the slide rod near the door.

[0013] Preferably, the partition is fixedly connected to the inner wall of the oven, and the inner cavity partition is fixedly connected to the inner wall of the oven.

[0014] Preferably, the outer wall of the inner cavity partition is fixedly connected with vertical protrusions, and the number of vertical protrusions is set in several groups, with the several groups of vertical protrusions being equally spaced on the outer wall of the inner cavity partition.

[0015] Compared with the prior art, this utility model provides a graphene nano-heating and baking device, which has the following beneficial effects:

[0016] 1. This graphene nano-heating and baking device, through its heating components and fan, blows air downwards from the oven, carrying heat from above downwards. This ensures uniform temperature distribution on the outer wall of the inner cavity partition. The airflow circulates within the oven, transferring heat from the upper part to the lower part, resulting in even temperature distribution. This ensures that paint layers at different heights on the painted parts inside the oven are heated evenly, preventing localized overheating or underheating. The airflow enters the inner cavity partition through a channel, preventing it from blowing directly onto the workpiece and avoiding excessively rapid evaporation of surface solvents, which could lead to a falsely dry paint film. Simultaneously, the hot air within the inner cavity partition is carried downwards. During the air circulation process within the oven, the hot air mixes thoroughly with other air, improving heating efficiency and forming a stable hot air circulation, thus enhancing baking consistency.

[0017] 2. This graphene nano-heating and baking device increases the contact area between the airflow and the outer wall of the inner cavity partition by setting vertical convex strips, allowing more hot air to come into contact with it, so that the entire inner cavity partition can reach a uniform temperature more quickly, reducing local overheating or low temperature, and improving the heat transfer rate.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a graphene nano-heating and baking device, including an oven 1, a door 2 hinged to the front of the oven 1, and a heating component 3 inside the oven 1. The heating component 3 includes an inner cavity partition 301, a graphene heating plate 302, a slide bar 303, a hook 304, a through groove 305, an air outlet 306, a partition 307, a return air inlet 308, an air inlet 309, a return air cavity 310, a motor 311, a rotating shaft 312, and a fan 313.

[0025] In one embodiment of this utility model, the inner cavity partition 301 is fixedly connected to the inner wall of the oven 1. A graphene heating plate 302 is fixedly connected to the inner wall of the inner cavity partition 301. A slide rod 303 is slidably connected to the top end face of the inner cavity partition 301. A handle is fixedly connected to the bottom end face of the slide rod 303. The handle is located on the side of the bottom of the slide rod 303 near the oven door 2. A hook 304 is fixedly connected to the bottom end face of the slide rod 303. A through groove 305 is opened on the side wall of the inner cavity partition 301. An air outlet 306 is opened on the bottom end face of the inner cavity partition 301. The inner cavity partition 301 is shaped like a shuttle. The through groove 305 is opened on the side of the inner cavity partition 301 away from the air outlet 306. The shuttle-shaped inner cavity partition 301 allows airflow to flow along the outer wall of the inner cavity partition 301, thereby making the temperature of the outer wall of the inner cavity partition 301 uniform.

[0026] The partition 307 is fixedly connected to the inner wall of the oven 1. The bottom of the partition 307 is provided with a return air vent 308 and the top of the partition 307 is provided with an air inlet 309. The partition 307 and the inner wall of the oven 1 are provided with a return air cavity 310. The return air cavity 310 connects the return air vent 308 and the air inlet 309. The airflow is blown downward by the fan 313, enters the return air cavity 310 through the return air vent 308, and then contacts the outer wall of the inner cavity partition 301 again through the air inlet 309 to realize the circulation of airflow. The motor 311 is fixedly connected to the top end face of the oven 1. The fan 313 is located directly above the inner cavity partition 301. The output end of the motor 311 is fixedly connected to the rotating shaft 312, and the fan 313 is fixedly connected to the side wall of the rotating shaft 312.

[0027] The graphene heating plate 302 heats the interior of the inner cavity partition 301, and simultaneously heats the inner cavity partition 301 in the opposite direction. The motor 311 drives the rotating shaft 312 and the fan 313 to rotate, blowing the air inside the oven 1 downwards. The spindle-shaped inner cavity partition 301 allows the airflow to flow along the outer wall of the inner cavity partition 301. The downward-flowing air can carry the heat from above downwards, thereby making the temperature of the outer wall of the inner cavity partition 301 uniform. Then, the airflow enters the return air cavity 310 through the return air inlet 308, and then contacts the outer wall of the inner cavity partition 301 again through the air inlet 309, realizing the circulation of airflow and transferring the heat from the upper part to the lower part, so that the temperature is evenly distributed. The paint layers of different heights inside the oven 1 can be heated evenly, avoiding local overheating or underheating.

[0028] Airflow enters the inner cavity partition 301 through the through groove 305. Due to the guidance of the through groove 305, the airflow flows along the inner wall of the inner cavity partition 301 instead of blowing directly onto the workpiece. This avoids the surface solvent evaporating too quickly, which would cause the paint film to be falsely dry on the surface but not fully cured inside, affecting adhesion and improving the surface quality of the painted parts. The airflow flows downward and forms a low-pressure zone on the inner wall of the inner cavity partition 301. This guides the hot air in the inner cavity partition 301 to the low-pressure zone, and then it is carried downward by the airflow. During the air circulation process in the oven 1, the hot air is fully mixed with other air, improving heating efficiency and forming a stable hot air circulation. This makes the temperature in the oven 1 more uniform, avoiding the problem of local overheating or underheating, and improving baking consistency.

[0029] In addition, vertical protrusions 4 are fixedly connected to the outer wall of the inner cavity partition 301. Several sets of vertical protrusions 4 are set at equal intervals on the outer wall of the inner cavity partition 301. The vertical protrusions 4 increase the contact area between the airflow and the outer wall of the inner cavity partition 301, allowing more hot air to come into contact with it, so that the entire inner cavity partition 301 can reach a uniform temperature more quickly, reducing local overheating or low temperature, improving the heat transfer rate, optimizing the hot air circulation path, making the heat energy distribution more uniform, improving the heat utilization rate, and reducing energy consumption.

[0030] In this invention, during use, the graphene heating plate 302 heats the interior of the inner cavity partition 301. The motor 311 drives the rotating shaft 312 and the fan 313 to rotate, blowing the air inside the oven 1 downwards. The airflow flows along the outer wall of the inner cavity partition 301, carrying the heat from above downwards, making the temperature of the outer wall of the inner cavity partition 301 uniform. The airflow enters the return air cavity 310 through the return air inlet 308, and then re-contacts the outer wall of the inner cavity partition 301 through the air inlet 309, realizing the circulation of airflow and making the temperature evenly distributed. The airflow enters the inner cavity partition 301 through the through groove 305, flows along the inner wall of the inner cavity partition 301, and forms a low-pressure area at the inner wall of the inner cavity partition 301 as the airflow flows downwards. This guides the hot air inside the inner cavity partition 301 to the low-pressure area, and then it is carried downwards by the airflow. During the air circulation process inside the oven 1, the hot air is fully mixed with other air, improving the heating efficiency.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
