Its operation quality and efficiency directly affect the service level and economic benefits of the repair company.
[0003] However, traditional paint drying equipment mostly heats auto parts or the entire vehicle from a single direction. This results in uneven heating of various parts of the car body and large temperature differences. Taking the car body as an example, the temperature of the roof and the bottom of the car may be very different during the paint baking due to different heat transfer paths and distances. This temperature difference will cause inconsistent drying speed of the paint surface, which will in turn cause the paint surface to be partially over-dried or not dry, reduce the adhesion and durability of the paint surface, and make the repaired paint surface prone to quality problems such as peeling and blistering.

[0034] As shown in the appended Figure 1 to the appended Figure 5As shown in the figure: The paint baking room 1 consists of a closed warehouse 101, a grille plate 102, a filter screen plate 103, and a ramp platform 9. The closed warehouse 101 is formed through welding or assembly processes to ensure the airtightness of the paint baking room 1, effectively preventing heat and harmful gases from leaking out. The grille plate 102 is installed inside the closed warehouse 101 by welding or bolts. The grille plate 102 plays a role in supporting the vehicle, the moving bracket 7, and guiding the air flow, ensuring the stable movement of the moving bracket 7 inside the paint baking room 1, and at the same time optimizing the air flow distribution so that the hot air flow can act more evenly on the vehicle parts or the whole vehicle. The ramp platform 9 is made of anti-slip metal material and is installed on the front of the closed warehouse 101 by welding or bolt connection. The ramp platform 9 facilitates the staff to drive the whole vehicle into the paint baking room 1, greatly improving the operation convenience.
[0035] As shown in the appendix Figure 5 As shown in the figure: The filter screen plate 103 is installed on the top of the closed warehouse 101 by a suitable fixing method, by bolts or snap connection. The filter screen plate 103 filters the hot air flow entering the paint baking room 1, intercepts the impurities therein, and prevents them from adhering to the surface of the vehicle parts, affecting the paint baking quality. The air outlet of the air outlet pipe 304 is located above the filter screen plate 103, so that the hot air flow enters the interior of the paint baking room 1 after being filtered by the filter screen plate 103, further ensuring the cleanliness of the paint baking environment.
[0036] As shown in the appendix Figure 2 As shown in the figure: The control terminal 2 is installed on the side of the paint baking room 1 and is connected to the various components of the device through data lines. The control terminal 2 uses industrial-grade control equipment and is equipped with corresponding control software, which can monitor and precisely control the operating status of the paint baking room 1 in real time, such as starting and stopping equipment such as the combustion furnace 501 and the blower 303, adjusting the opening degree of the air damper 305 to control the air flow rate, receiving and analyzing the color difference and temperature data feedback by the scanning head 801, and then dynamically adjusting the heating parameters to achieve intelligent control of the paint baking and drying process.
[0037] As shown in the appendix Figure 1 To the appendix Figure 5 As shown in the figure: The hot air circulation system 3 is installed on the side of the paint baking room 1 and consists of a protective cover 301, an air outlet pipe 304, an air inlet pipe 302, a blower 303, an air damper 305, and a lower air outlet component 6, etc. The protective cover 301 uses a metal shell, and the interior is separated into a heat exchange chamber and an air inlet chamber by a partition. This structural design effectively isolates different functional areas, avoids air flow interference with each other, and ensures the stable operation of the hot air circulation system 3. One end of the air outlet pipe 304 is connected to the top of the heat exchange chamber, and the other end is connected to the top of the paint baking room 1, and is installed by welding or flange connection. The air outlet pipe 304 transports the hot air flow in the heat exchange chamber to the top of the paint baking room 1 to heat the vehicle parts or the whole vehicle from above. The air inlet pipe 302 is installed on the air inlet chamber and is used to introduce fresh air from the outside to provide the necessary oxygen for the combustion of the combustion furnace 501 and the generation of the hot air flow.
[0038] The blower 303 is arranged below the heating component 5 and is connected to the air inlet chamber. The blower 303 pressurizes and sends the outside air into the air inlet chamber, accelerating the air flow and improving the combustion efficiency of the combustion furnace 501, so as to quickly generate a hot air flow. The air damper 305 is arranged between the protective cover 301 and the blower 303, and an electric air damper can be adopted. When it is necessary to adjust the air flow in the heat exchange chamber to control the temperature in the paint baking room 1, the opening degree of the air damper 305 can be remotely operated through the control terminal 2 to achieve effective control of the temperature.
[0039] As shown in the Figure 2 accompanying drawings: The heating component 5 is arranged below the air outlet pipe 304 in the heat exchange chamber and consists of a combustion furnace 501 and an exhaust pipe 502. The combustion furnace 501 adopts professional combustion equipment and is installed in the heat exchange chamber.

The exhaust pipe 502 is connected to the combustion furnace 501, and the end passes through the protective cover 301 and extends to the outside of the paint baking room 1. The exhaust pipe 502 discharges the waste gas generated by the combustion of the combustion furnace 501 from the paint baking room 1, ensuring the cleanliness of the air in the paint baking room 1 and avoiding the harm of waste gas to automotive parts and operators.
[0040] As shown in the Figure 3 to the Figure 5 accompanying drawings: The lower air outlet component 6 is installed on the side of the paint baking room 1 and consists of an induced draft fan 601, a guide pipe 602, an air outlet pipe 604 and a pipe connector 603. Both ends of the induced draft fan 601 are connected with a guide pipe 602. One guide pipe 602 is communicated with the air outlet pipe 304, and the end of the other guide pipe 602 passes through the side wall of the closed warehouse 101 and enters the inside of the closed warehouse 101. The induced draft fan 601 introduces part of the hot air flow in the air outlet pipe 304 into the bottom of the closed warehouse 101, realizing the heating of automotive parts or the whole vehicle from two directions of up and down by the hot air flow, effectively reducing the temperature difference between different parts of the vehicle body or parts, and improving the paint baking quality. The lower end of the guide pipe 602 passes through the grille plate 102 and is conducted with the air outlet pipe 604. The air outlet pipe 604 is arranged below the grille plate 102, and several air outlet pipes 604 are mutually conducted. This connection method enables the hot air flow to flow uniformly from bottom to top, further optimizing the temperature distribution in the paint baking room 1. The pipe connector 603 is arranged on the guide pipe 602 and is located above the grille plate 102. The pipe connector 603 is communicated with the auxiliary air outlet 802 through a hose, guiding part of the hot air flow to the auxiliary air outlet 802 for further blowing and drying at the paint repair position, improving the drying efficiency and effect.
[0041] As shown in the Figure 3 to the Figure 5As shown in the figure: The return pipe fitting 4 is installed on the side of the enclosed warehouse 101 and consists of a return air pipe 401 and a dust-proof net 402. One end of the return air pipe 401 is connected to the side of the enclosed warehouse 101, and the other end is connected to the heat exchange chamber and is installed by welding or flange connection. The return air pipe 401 returns the hot air in the paint baking room 1 to the heat exchange chamber, forming an efficient air flow circulation path, making full use of heat and reducing energy waste. The dust-proof net 402 is installed on the return air pipe 401 to intercept dust in the air flow and prevent it from entering the heat exchange chamber, ensuring a clean environment in the paint baking room 1 and extending the service life of each component of the device.
[0042] As shown in the appendix Figure 6 to the appendix Figure 7 As shown in the figure: The mobile support 7 is arranged on the grille plate 102 in the paint baking room 1 and consists of a mobile vehicle 701 and a folding arm 702. The mobile vehicle 701 is made of a metal frame and wheels and can move freely on the grille plate 102, facilitating the staff to adjust its position. The folding arm 702 is installed on the mobile vehicle 701 and consists of two connecting plates 7021 with hinged ends, a rotating shaft 7022, and a mounting bracket 7023. One end of the two connecting plates 7021 away from each other is respectively hinged with a rotating shaft 7022 and a mounting bracket 7023, and the rotating shaft 7022 is rotatably arranged on the mobile vehicle 701. This hinged structure enables the folding arm 702 to rotate and fold flexibly, further expanding the working range of the scanning head 801 and the auxiliary air outlet 802.
[0043] As shown in the appendix Figure 3 to the appendix Figure 5 As shown in the figure: The auxiliary paint baking assembly 8 is installed at the movable end of the folding arm 702 and consists of a scanning head 801 and an auxiliary air outlet 802. The scanning head 801 includes a color difference meter 8011 and an infrared imager 8012, which can scan the color and temperature of the paint replenishment position in real time and feed the data back to the control terminal 2. The control terminal 2 dynamically adjusts the heating parameters according to the feedback data to prevent over-drying or insufficient drying.
