Description

Technical Field

[0001] This utility model relates to the field of coating oven technology, and in particular to a coating oven and its temperature uniformity adjustment component. Background Technology

[0002] A coating oven is a device that applies coating materials to a substrate and then bakes it. Its working principle involves applying the coating material to the substrate and then sending it into the working chamber of the coating oven for baking. Inside the oven, the coating material is subjected to high temperatures, causing it to solidify and form a tough coating. Hot air heating is one of the commonly used heating methods in coating ovens. The hot air system heats the substrate by spraying hot air, allowing the coating material to dry rapidly at high temperatures. Specifically, the oven's interior is equipped with a circulating blower, a heater, and a filter. During operation, the circulating blower blows air through an air duct to the heater. A filter with evenly distributed mesh holes is installed above the heater to filter the hot air. The filtered hot air then enters the working area to bake the coating on the substrate.

[0003] The temperature uniformity of coating ovens needs to be measured regularly each month. Insufficient temperature uniformity will severely reduce the baking quality of the coating machine. During the coating process, the coating may contain flammable components. If localized overheating occurs inside the oven, it may cause fires or other safety accidents. Traditionally, the temperature uniformity of coating ovens is mainly adjusted using the exhaust duct at the top of the oven to maintain uniform hot air flow and prevent hot air from accumulating in one area. This requires operators to make multiple adjustments based on experience to achieve the ideal temperature distribution, which is difficult, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of this, this application aims to at least partially solve the problems in the related technology. One of the objectives of this application is to provide a coating oven temperature uniformity adjustment component, including: an air guide; the air guide is disposed on the side of the filter screen away from the heater; the air guide is provided with a plurality of ventilation holes; the air guide is provided with a plurality of angle adjustment components for adjusting the size of the ventilation holes.

[0005] During coating oven operation, hot air from the heater is filtered by a filter. The filtered hot air then passes through ventilation holes on the air guide and enters the working area to bake the coating on the substrate. When adjusting the temperature, adjusting the angle adjustment component changes the size of the ventilation holes in specific areas of the air guide, thereby altering the flow rate of hot air through those areas and changing the temperature within those areas. Specifically, when the temperature in a certain area is high, adjusting the angle adjustment component on the corresponding air guide makes the ventilation holes smaller, reducing the flow rate of hot air through that area and thus reducing the heat delivered, resulting in a lower temperature in that area. The flow rate of hot air to other areas increases accordingly. Conversely, when the temperature in a certain area is low, adjusting the angle adjustment component on the corresponding air guide makes the ventilation holes larger, increasing the flow rate of hot air through that area and thus increasing the heat delivered, thereby raising the temperature in that area. This adjustment can also be used in conjunction with adjustments to the air guides for other areas to reduce the flow rate of hot air in those areas and increase the flow rate through this area, thereby raising the temperature in this area.

[0006] This application utilizes an air guide to regulate the temperature uniformity of the coating oven, exhibiting excellent stability and precision. Compared to the traditional method of adjusting temperature uniformity using exhaust ducts, this application's method is more convenient and faster, effectively controlling the coating oven's temperature uniformity within 3 degrees Celsius, reducing equipment failure rates, significantly improving the oven's uptime, effectively preventing localized overheating, reducing fire risks, and enhancing production safety.

[0007] In a preferred embodiment of this invention, the air guide includes: an adjusting plate A and several adjusting plates B; both the adjusting plate A and the adjusting plate B are provided with several ventilation holes; the adjusting plate A and the adjusting plate B are adjacent to each other and are located on the side of the filter screen away from the heater; the angle adjusting member is provided on the adjusting plate A and / or the adjusting plate B.

[0008] The size of regulating plate A is made according to the size of the filter screen. Regulating plate B can be placed on the side of regulating plate A closer to the filter screen, or on the side of regulating plate A farther away from the filter screen. There is a certain gap between adjacent regulating plates B. When adjusting the temperature, the regulating plates B in each area are adjusted separately.

[0009] In a preferred embodiment of this utility model, the angle adjusting component includes: M oblong holes; the oblong holes are disposed on the adjusting plate A; a fixing member connected to the adjusting plate B is disposed in the oblong holes; there is a certain gap between adjacent adjusting plates B; and M is an integer greater than 0.

[0010] The length of the oblong hole is set according to the displacement range of the adjusting plate B. The fixing component, in conjunction with the oblong hole, controls the displacement of B relative to A. The fixing component also securely connects adjusting plate B and adjusting plate A, preventing relative displacement after the angle is adjusted. Specifically, when adjusting the angle, loosen the fixing component and move adjusting plate B so that the ventilation holes on adjusting plate B coincide with or are misaligned with the ventilation holes on adjusting plate A. This adjusts the size of the superimposed ventilation holes, changing the flow rate of hot air through this area and achieving temperature regulation. After the angle is adjusted, tighten the fixing component to prevent relative displacement between adjusting plate B and adjusting plate A.

[0011] The main function of the angle adjustment component is to adjust the size of the ventilation hole. The specific structure of the angle adjustment component can also refer to other structures in the prior art, such as using a slider to block the ventilation hole or controlling it through an intelligent system.

[0012] In a preferred embodiment of this invention, the fixing component includes a fixing screw; the fixing screw passes through the oblong hole and connects to the adjusting plate B.

[0013] When angle adjustment is required, loosen the fixing screws to move the adjusting plate B. This changes the relative position of adjusting plate B and adjusting plate A, causing the ventilation holes on adjusting plate B and adjusting plate A to overlap or misalign. This adjusts the size of the superimposed ventilation holes, changing the flow rate of hot air through this area and thus regulating the temperature. After angle adjustment, tighten the fixing screws to lock adjusting plate B and adjusting plate A together, preventing relative displacement between them.

[0014] Specifically, the ratio of the number of adjustment plates A to the number of adjustment plates B is 1:6.

[0015] The ratio of adjustment plate A to adjustment plate B is 1:6. Six adjustment plates B are evenly distributed on one adjustment plate A. When adjusting the temperature, it can be adjusted in six separate areas to achieve good temperature uniformity regulation of the oven.

[0016] Specifically, the adjusting plate A and the adjusting plate B are stainless steel adjusting plates or aluminum alloy adjusting plates.

[0017] Stainless steel or aluminum alloy possesses excellent thermal conductivity and high-temperature resistance, enabling it to withstand the high-temperature environment inside the coating oven. The stainless steel or aluminum alloy adjustment plates A and B also have a certain load-bearing capacity, preventing falling clamps or plates from damaging the filter screen. They can also support operators entering the oven to inject lubricating oil, reducing equipment failure rates. Before the adjustment plates are installed, the filter screen lacks load-bearing capacity, requiring operators to turn off the heating and remove the filter screen before entering the oven, which is time-consuming and laborious.

[0018] In a preferred embodiment of this invention, a plurality of heating components are provided on the side of the adjusting plate A away from the adjusting plate B.

[0019] Several heating components are respectively installed in different areas on the regulating plate A. When the temperature of a certain area is lower than the average temperature, the heating component in that area can be turned on to heat the hot air and raise the temperature of that area.

[0020] In a preferred embodiment of this invention, the heating assembly includes a heating wire and a filter cover; the heating wire is disposed on the side of the adjusting plate A away from the adjusting plate B; the heating wire is located inside the filter cover.

[0021] When the temperature in a certain area is lower than the average temperature, it can be adjusted by changing the size of the ventilation openings, or by using heating wires to reheat the hot air in that area. The filter cover can filter and retain dust and impurities in the air, preventing them from entering the inner cavity and damaging the heating wires. When the temperature in a certain area is significantly lower than the average temperature, temperature regulation can be achieved by combining the adjustment of the ventilation opening size and the activation of the heating wires, thereby improving the ability to control the temperature.

[0022] In a preferred embodiment of this invention, a height adjustment component is further included; the height adjustment component is disposed between the air guide and the filter screen.

[0023] When the air guide is close to the filter, the thermal resistance is high; conversely, the thermal resistance is low. When the temperature in the working area is low, adjust the height adjustment to increase the distance between the air guide and the filter, reduce thermal resistance, improve thermal conductivity, and raise the temperature in the working area. When the temperature in the working area is high, adjust the height adjustment to decrease the distance between the air guide and the filter, increase thermal resistance, and lower the temperature in the working area.

[0024] The main function of the height adjustment component is to adjust the distance between the air guide and the filter. Its specific structure can also be found in other existing structures, such as those using compression springs or intelligent lifting systems.

[0025] In a preferred embodiment of this invention, the height adjustment component includes: a plurality of adjustment bolts; each adjustment bolt includes a bolt rod and a nut; the bolt rod passes through the air guide and the nut respectively and is connected to the filter screen; the nut abuts against the air guide.

[0026] Height adjustment using adjusting bolts is not only simple to operate but also adaptable to various occasions and different height requirements. During height adjustment, the distance between the air guide and the filter screen is adjusted by changing the position of the air guide on the bolt rod. Several adjusting bolts positioned at different locations on the air guide help to better support the air guide above the filter screen, improving its stability.

[0027] In a preferred embodiment of this invention, the air guide is provided with several temperature sensors.

[0028] The temperature sensors are characterized by high accuracy and reliability. Distributing several temperature sensors across different areas of the air guide allows operators to monitor the temperature distribution in different areas of the coating oven in real time. Specifically, the temperature sensors are detachably mounted on the air guide and are electrically connected to the control system. Each temperature sensor has a human-machine interface, allowing operators to set relevant parameters. When the temperature difference between the local area and the overall average temperature of the coating oven exceeds 3 degrees Celsius (i.e., the temperature uniformity of the local area is within ±3 degrees Celsius), the control system will issue an alarm, prompting adjustments. Operators can then make timely adjustments based on the feedback, improving the convenience and accuracy of temperature adjustments.

[0029] The second objective of this application is to provide a coating oven, including a temperature uniformity adjustment component as described above. The coating oven structure does not require redesign; only the adjustment component of this application needs to be added above the filter screen. This not only facilitates temperature uniformity adjustment of the coating oven, but also provides the air guide with a certain load-bearing capacity, protecting the filter screen from damage by sudden drops or falling plates, and allowing personnel easy access for oven maintenance.

[0030] Compared with the prior art, the technical solution provided in this application has the following advantages: When the coating oven is running, the hot air from the heater is sent to the filter for filtration. The filtered hot air then passes through the ventilation holes on the air guide and enters the working area to bake the coating on the substrate. When adjusting the temperature, adjusting the angle adjustment component can change the size of the ventilation holes in a specific area on the air guide, thereby changing the flow rate of hot air through this area and changing the temperature of this area. Specifically, when the temperature of a certain area is high, adjusting the angle adjustment component on the corresponding air guide makes the ventilation holes smaller, the flow rate of hot air through this area decreases accordingly, and the heat brought by the hot air also decreases, resulting in a lower temperature in this area, while the flow rate of hot air to other areas increases accordingly. When the temperature of a certain area is low, adjusting the angle adjustment component on the corresponding air guide makes the ventilation holes larger, the flow rate of hot air through this area increases accordingly, and the heat brought by the hot air also increases, thereby raising the temperature of this area. It can also be used in conjunction with the air guides of other areas to reduce the flow rate of hot air in other areas, increase the flow rate of hot air through this area, and thus raise the temperature of this area.

[0031] This application utilizes an air guide to regulate the temperature uniformity of the coating oven, exhibiting excellent stability and precision. Compared to the traditional method of adjusting temperature uniformity using exhaust ducts, this application's method is more convenient and faster, effectively controlling the coating oven's temperature uniformity within 3 degrees Celsius, reducing equipment failure rates, significantly improving the oven's uptime, effectively preventing localized overheating, reducing fire risks, and enhancing production safety.

[0044] Example 1

[0045] like Figures 1-4 As shown, this embodiment provides a coating oven temperature uniformity adjustment component, including: an air guide; the air guide is disposed on the side of the filter away from the heater; the air guide is provided with a plurality of ventilation holes 11; the air guide is provided with a plurality of angle adjustment components for adjusting the size of the ventilation holes 11; the angle adjustment components are used to adjust the size of the ventilation holes 11.

[0046] During coating oven operation, hot air from the heater is filtered by a filter, and then passes through the ventilation holes 11 on the air guide to enter the working area to bake the coating on the substrate. When adjusting the temperature, adjusting the angle adjustment component changes the size of the ventilation holes 11 in a specific area of ​​the air guide, thereby changing the flow rate of hot air through that area and thus the temperature of that area. Specifically, when the temperature of a certain area is high, adjusting the angle adjustment component on the corresponding air guide for that area makes the ventilation holes 11 smaller, thus reducing the flow rate of hot air through that area and the amount of heat brought by the hot air, resulting in a lower temperature in that area, while increasing the flow rate of hot air to other areas. When the temperature of a certain area is low, adjusting the angle adjustment component on the corresponding air guide for that area makes the ventilation holes 11 larger, thus increasing the flow rate of hot air through that area and the amount of heat brought by the hot air, thereby raising the temperature of that area. This adjustment can also be used in conjunction with the air guides for other areas to reduce the flow rate of hot air in other areas and increase the flow rate of hot air through this area, thereby raising the temperature of this area.

[0047] This application utilizes an air guide to regulate the temperature uniformity of the coating oven, exhibiting excellent stability and precision. Compared to the traditional method of adjusting temperature uniformity using exhaust ducts, this application's method is more convenient and faster, effectively controlling the coating oven's temperature uniformity within 3 degrees Celsius, reducing equipment failure rates, significantly improving the oven's uptime, effectively preventing localized overheating, reducing fire risks, and enhancing production safety.

[0048] Preferably, the air guide includes: an adjusting plate A12 and a plurality of adjusting plates B13; both the adjusting plate A12 and the adjusting plate B13 are provided with a plurality of ventilation holes 11; the adjusting plate A12 and the adjusting plate B13 are adjacent to each other and are located on the side of the filter screen away from the heater; the angle adjusting member is provided on the adjusting plate A12 and / or the adjusting plate B13.

[0049] Specifically, the size of the regulating plate A12 is made according to the size of the filter screen. It can be a single regulating plate A12 of the same size as the filter screen, or multiple regulating plates A12 can be used to cover the filter screen for temperature adjustment. In this embodiment, one regulating plate A12 completely covers the filter screen for temperature regulation. The regulating plate B13 is located on the side of the regulating plate A12 closest to the filter screen. In practice, the regulating plate B13 can also be located on the side of the regulating plate A12 furthest from the filter screen. There is a certain gap between adjacent regulating plates B13. When adjusting the temperature, the regulating plates B13 of the six zones are adjusted separately. In this embodiment, the position and size of the ventilation holes 11 on the regulating plate A12 are the same as those on the regulating plate B13. After adjusting the angle adjustment component, the ventilation holes 11 on the regulating plate A12 and the ventilation holes 11 on the regulating plate B13 can either completely overlap or be misaligned, changing the flow rate of hot air through this zone, thereby regulating the temperature of this zone.

[0050] Preferably, the angle adjusting component includes: M oblong holes 121; the oblong holes 121 are disposed on the adjusting plate A12; a fixing member connected to the adjusting plate B13 is disposed in the oblong holes 121; there is a certain gap between adjacent adjusting plates B13; M is an integer greater than 0.

[0051] The length of the oblong hole 121 is specifically set according to the displacement range of the adjusting plate B13. The fixing component, in conjunction with the oblong hole 121, is used to control the displacement of B relative to A. The fixing component also fixes the adjusting plate B13 and the adjusting plate A12 in place, preventing relative displacement between the two after the angle is adjusted. In this embodiment, there are a total of 12 oblong holes 121 on each adjusting plate A12, and every two oblong holes 121 are used to adjust the displacement of one adjusting plate B13. When adjusting the angle, the fixing component is loosened, and the adjusting plate B13 is moved so that the ventilation hole 11 on the adjusting plate B13 coincides with or is misaligned with the ventilation hole 11 on the adjusting plate A12. This adjusts the size of the superimposed ventilation hole 11, changes the flow rate of hot air through this area, and achieves the purpose of temperature regulation. After the angle is adjusted, the fixing component is locked to prevent relative displacement between the adjusting plate B13 and the adjusting plate A12.

[0052] The main function of the angle adjustment component is to adjust the size of the ventilation hole 11. The specific structure of the angle adjustment component can also refer to other structures in the prior art, such as using a slider to block the ventilation hole 11 or controlling it through an intelligent system.

[0053] Preferably, the fixing component includes a fixing screw 131; the fixing screw 131 passes through the oblong hole 121 and is connected to the adjusting plate B13.

[0054] When angle adjustment is required, loosen the fixing screw 131, causing the fixing screw 131 to move the adjusting plate B13. This changes the relative position of the adjusting plate B13 and the adjusting plate A12, resulting in the ventilation holes 11 on the adjusting plate B13 and A12 either coinciding or misaligning. This adjusts the size of the superimposed ventilation holes 11, changing the flow rate of hot air through this area and achieving temperature regulation. After angle adjustment, tighten the fixing screw 131 to lock the adjusting plate B13 and adjusting plate A12 together, preventing relative displacement between them. In this embodiment, each adjusting plate B13 is connected to two fixing screws 131, ensuring a good fixing effect between the adjusting plate B13 and adjusting plate A12.

[0055] Preferably, a plurality of heating components are provided on the side of the adjusting plate A12 away from the adjusting plate B13.

[0056] Several heating components are respectively installed in different areas of the regulating plate A12. When the temperature of a certain area is lower than the average temperature, the heating component in that area can be turned on to heat the hot air and raise the temperature of that area.

[0057] Preferably, the heating assembly includes a heating wire and a filter cover; the heating wire is disposed on the side of the adjusting plate A away from the adjusting plate B13; the heating wire is located in the inner cavity of the filter cover.

[0058] When the temperature in a certain area is lower than the average temperature, it can be adjusted by changing the size of the ventilation openings, or by using heating wires to reheat the hot air in that area. The filter cover can filter and retain dust and impurities in the air, preventing them from entering the inner cavity and damaging the heating wires. When the temperature in a certain area is significantly lower than the average temperature, temperature regulation can be achieved by combining the adjustment of the ventilation opening size and the activation of the heating wires, thereby improving the ability to control the temperature.

[0059] Preferably, the ratio of the number of adjustment plates A12 to the number of adjustment plates B13 is 1:6.

[0060] The ratio of adjustment plate A12 to adjustment plate B13 is 1:6. Six adjustment plates B13 are evenly distributed on one adjustment plate A12. When adjusting the temperature, it can be adjusted in six separate areas to achieve good temperature uniformity adjustment of the oven.

[0061] Preferably, the adjusting plate A12 and the adjusting plate B13 are stainless steel adjusting plates or aluminum alloy adjusting plates.

[0062] Stainless steel or aluminum alloy has excellent thermal conductivity and high-temperature resistance, enabling it to withstand the high-temperature environment inside the coating oven. The stainless steel or aluminum alloy adjusting plates A12 and B13 also have a certain load-bearing capacity, preventing falling clamps or plates from damaging the filter screen. They can also support operators entering the oven to inject lubricating oil, reducing equipment failure rates. Before the adjusting plates are installed, the filter screen lacks load-bearing capacity, requiring operators to turn off the heating and remove the filter screen before entering the oven, which is time-consuming and laborious.

[0063] Example 2

[0064] like Figures 1-4 As shown, this embodiment provides a coating oven temperature uniformity adjustment component, including: an air guide; the air guide is disposed on the side of the filter away from the heater; the air guide is provided with a plurality of ventilation holes 11; the air guide is provided with a plurality of angle adjustment components for adjusting the size of the ventilation holes 11; the angle adjustment components are used to adjust the size of the ventilation holes 11.

[0065] During coating oven operation, hot air from the heater is filtered by a filter, and then passes through the ventilation holes 11 on the air guide to enter the working area to bake the coating on the substrate. When adjusting the temperature, adjusting the angle adjustment component changes the size of the ventilation holes 11 in a specific area of ​​the air guide, thereby changing the flow rate of hot air through that area and thus the temperature of that area. Specifically, when the temperature of a certain area is high, adjusting the angle adjustment component on the corresponding air guide for that area makes the ventilation holes 11 smaller, thus reducing the flow rate of hot air through that area and the amount of heat brought by the hot air, resulting in a lower temperature in that area, while increasing the flow rate of hot air to other areas. When the temperature of a certain area is low, adjusting the angle adjustment component on the corresponding air guide for that area makes the ventilation holes 11 larger, thus increasing the flow rate of hot air through that area and the amount of heat brought by the hot air, thereby raising the temperature of that area. This adjustment can also be used in conjunction with the air guides for other areas to reduce the flow rate of hot air in other areas and increase the flow rate of hot air through this area, thereby raising the temperature of this area.

[0066] This application utilizes an air guide to regulate the temperature uniformity of the coating oven, exhibiting excellent stability and precision. Compared to the traditional method of adjusting temperature uniformity using exhaust ducts, this application's method is more convenient and faster, effectively controlling the coating oven's temperature uniformity within 3 degrees Celsius, reducing equipment failure rates, significantly improving the oven's uptime, effectively preventing localized overheating, reducing fire risks, and enhancing production safety.

[0067] Preferably, it also includes a height adjustment component; the height adjustment component is disposed between the air guide and the filter screen.

[0068] When the air guide is close to the filter, the thermal resistance is high; conversely, the thermal resistance is low. When the temperature in the working area is low, adjust the height adjustment to increase the distance between the air guide and the filter, reduce thermal resistance, improve thermal conductivity, and raise the temperature in the working area. When the temperature in the working area is high, adjust the height adjustment to decrease the distance between the air guide and the filter, increase thermal resistance, and lower the temperature in the working area.

[0069] The main function of the height adjustment component is to adjust the distance between the air guide and the filter. Its specific structure can also be found in other existing structures, such as those using compression springs or intelligent lifting systems.

[0070] Preferably, the height adjustment component includes: a plurality of adjustment bolts 21; each adjustment bolt 21 includes a bolt rod and a nut; the bolt rod passes through the air guide and the nut respectively and is connected to the filter screen; the nut abuts against the air guide.

[0071] Height adjustment using adjusting bolts 21 is not only simple to operate but also adaptable to various occasions and different height requirements. During height adjustment, the distance between the air guide and the filter screen is adjusted by changing the position of the air guide on the bolt rod. In this embodiment, four adjusting bolts 21 are provided, located at the four corners of the adjusting plate A12. This facilitates height adjustment and better supports the air guide above the filter screen, improving its stability. To adjust the height, loosen the nut on the bolt rod, then adjust the distance between the adjusting plate A12 and the filter screen. After adjusting the distance, tighten the nut until it abuts against the adjusting plate A12, preventing it from slipping off the bolt rod. The height adjustment is then complete. To further stabilize the adjusting plate A12 on the bolt rod, another nut can be added to abut against it, fixing the adjusting plate A12 between the two nuts on the bolt rod, thus enhancing its stability.

[0072] Preferably, the air guide is equipped with several temperature sensors.

[0073] The temperature sensors are characterized by high accuracy and reliability. Distributing several temperature sensors across different areas of the air guide allows operators to monitor the temperature distribution in different areas of the coating oven in real time. Specifically, the temperature sensors are detachably mounted on the adjustment plate A12 and are electrically connected to the control system. A human-machine interface is provided on the temperature sensors, allowing operators to set relevant parameters. When the temperature difference between the local area and the overall average temperature of the coating oven exceeds 3 degrees Celsius (i.e., the temperature sensor detects a temperature uniformity exceeding ±3 degrees Celsius), it triggers an alarm in the control system, indicating the need for adjustment. Operators can then make timely adjustments based on the feedback, improving the convenience and accuracy of temperature adjustment.

[0074] Example 3

[0075] like Figures 1-4 As shown, this embodiment provides a coating oven temperature uniformity adjustment component, including: an air guide; the air guide is disposed on the side of the filter away from the heater; the air guide is provided with a plurality of ventilation holes 11; the air guide is provided with a plurality of angle adjustment components for adjusting the size of the ventilation holes 11; the angle adjustment components are used to adjust the size of the ventilation holes 11.

[0076] During coating oven operation, hot air from the heater is filtered by a filter, and then passes through the ventilation holes 11 on the air guide to enter the working area to bake the coating on the substrate. When adjusting the temperature, adjusting the angle adjustment component changes the size of the ventilation holes 11 in a specific area of ​​the air guide, thereby changing the flow rate of hot air through that area and thus the temperature of that area. Specifically, when the temperature of a certain area is high, adjusting the angle adjustment component on the corresponding air guide for that area makes the ventilation holes 11 smaller, thus reducing the flow rate of hot air through that area and the amount of heat brought by the hot air, resulting in a lower temperature in that area, while increasing the flow rate of hot air to other areas. When the temperature of a certain area is low, adjusting the angle adjustment component on the corresponding air guide for that area makes the ventilation holes 11 larger, thus increasing the flow rate of hot air through that area and the amount of heat brought by the hot air, thereby raising the temperature of that area. This adjustment can also be used in conjunction with the air guides for other areas to reduce the flow rate of hot air in other areas and increase the flow rate of hot air through this area, thereby raising the temperature of this area.

[0077] This application utilizes an air guide to regulate the temperature uniformity of the coating oven, exhibiting excellent stability and precision. Compared to the traditional method of adjusting temperature uniformity using exhaust ducts, this application's method is more convenient and faster, effectively controlling the coating oven's temperature uniformity within 3 degrees Celsius, reducing equipment failure rates, significantly improving the oven's uptime, effectively preventing localized overheating, reducing fire risks, and enhancing production safety.

[0078] Preferably, the air guide includes: an adjusting plate A12 and a plurality of adjusting plates B13; both the adjusting plate A12 and the adjusting plate B13 are provided with a plurality of ventilation holes 11; the adjusting plate A12 and the adjusting plate B13 are adjacent to each other and are located on the side of the filter screen away from the heater; the angle adjusting member is provided on the adjusting plate A12 and / or the adjusting plate B13.

[0079] Specifically, the size of the regulating plate A12 is made according to the size of the filter screen. It can be a single regulating plate A12 of the same size as the filter screen, or multiple regulating plates A12 can be used to cover the filter screen for temperature adjustment. In this embodiment, one regulating plate A12 completely covers the filter screen for temperature regulation. The regulating plate B13 is located on the side of the regulating plate A12 closest to the filter screen. In practice, the regulating plate B13 can also be located on the side of the regulating plate A12 furthest from the filter screen. There is a certain gap between adjacent regulating plates B13. When adjusting the temperature, the regulating plates B13 of the six zones are adjusted separately. In this embodiment, the position and size of the ventilation holes 11 on the regulating plate A12 are the same as those on the regulating plate B13. After adjusting the angle adjustment component, the ventilation holes 11 on the regulating plate A12 and the ventilation holes 11 on the regulating plate B13 can either completely overlap or be misaligned, changing the flow rate of hot air through this zone, thereby regulating the temperature of this zone.

[0080] Preferably, the angle adjusting component includes: M oblong holes 121; the oblong holes 121 are disposed on the adjusting plate A12; a fixing member connected to the adjusting plate B13 is disposed in the oblong holes 121; there is a certain gap between adjacent adjusting plates B13; M is an integer greater than 0.

[0081] The length of the oblong hole 121 is specifically set according to the displacement range of the adjusting plate B13. The fixing component, in conjunction with the oblong hole 121, is used to control the displacement of B relative to A. The fixing component also fixes the adjusting plate B13 and the adjusting plate A12 in place, preventing relative displacement between the two after the angle is adjusted. In this embodiment, there are a total of 12 oblong holes 121 on each adjusting plate A12, and every two oblong holes 121 are used to adjust the displacement of one adjusting plate B13. When adjusting the angle, the fixing component is loosened, and the adjusting plate B13 is moved so that the ventilation hole 11 on the adjusting plate B13 coincides with or is misaligned with the ventilation hole 11 on the adjusting plate A12. This adjusts the size of the superimposed ventilation hole 11, changes the flow rate of hot air through this area, and achieves the purpose of temperature regulation. After the angle is adjusted, the fixing component is locked to prevent relative displacement between the adjusting plate B13 and the adjusting plate A12.

[0082] The main function of the angle adjustment component is to adjust the size of the ventilation hole 11. The specific structure of the angle adjustment component can also refer to other structures in the prior art, such as using a slider to block the ventilation hole 11 or controlling it through an intelligent system.

[0083] Preferably, the fixing component includes a fixing screw 131; the fixing screw 131 passes through the oblong hole 121 and is connected to the adjusting plate B13.

[0084] When angle adjustment is required, loosen the fixing screw 131, causing the fixing screw 131 to move the adjusting plate B13. This changes the relative position of the adjusting plate B13 and the adjusting plate A12, resulting in the ventilation holes 11 on the adjusting plate B13 and A12 either coinciding or misaligning. This adjusts the size of the superimposed ventilation holes 11, changing the flow rate of hot air through this area and achieving temperature regulation. After angle adjustment, tighten the fixing screw 131 to lock the adjusting plate B13 and adjusting plate A12 together, preventing relative displacement between them. In this embodiment, each adjusting plate B13 is connected to two fixing screws 131, ensuring a good fixing effect between the adjusting plate B13 and adjusting plate A12.

[0085] Preferably, a plurality of heating components are provided on the side of the adjusting plate A12 away from the adjusting plate B13.

[0086] Several heating components are respectively installed in different areas of the regulating plate A12. When the temperature of a certain area is lower than the average temperature, the heating component in that area can be turned on to heat the hot air and raise the temperature of that area.

[0087] Preferably, the heating assembly includes a heating wire and a filter cover; the heating wire is disposed on the side of the adjusting plate A away from the adjusting plate B13; the heating wire is located in the inner cavity of the filter cover.

[0088] When the temperature in a certain area is lower than the average temperature, it can be adjusted by changing the size of the ventilation openings, or by using heating wires to reheat the hot air in that area. The filter cover can filter and retain dust and impurities in the air, preventing them from entering the inner cavity and damaging the heating wires. When the temperature in a certain area is significantly lower than the average temperature, temperature regulation can be achieved by combining the adjustment of the ventilation opening size and the activation of the heating wires, thereby improving the ability to control the temperature.

[0089] Preferably, the ratio of the number of adjustment plates A12 to the number of adjustment plates B13 is 1:6.

[0090] The ratio of adjustment plate A12 to adjustment plate B13 is 1:6. Six adjustment plates B13 are evenly distributed on one adjustment plate A12. When adjusting the temperature, it can be adjusted in six separate areas to achieve good temperature uniformity adjustment of the oven.

[0091] Preferably, the adjusting plate A12 and the adjusting plate B13 are stainless steel adjusting plates or aluminum alloy adjusting plates.

[0092] Stainless steel or aluminum alloy has excellent thermal conductivity and high-temperature resistance, enabling it to withstand the high-temperature environment inside the coating oven. The stainless steel or aluminum alloy adjusting plates A12 and B13 also have a certain load-bearing capacity, preventing falling clamps or plates from damaging the filter screen. They can also support operators entering the oven to inject lubricating oil, reducing equipment failure rates. Before the adjusting plates are installed, the filter screen lacks load-bearing capacity, requiring operators to turn off the heating and remove the filter screen before entering the oven, which is time-consuming and laborious.

[0093] Preferably, it also includes a height adjustment component; the height adjustment component is disposed between the air guide and the filter screen.

[0094] When the air guide is close to the filter, the thermal resistance is high; conversely, the thermal resistance is low. When the temperature in the working area is low, adjust the height adjustment to increase the distance between the air guide and the filter, reduce thermal resistance, improve thermal conductivity, and raise the temperature in the working area. When the temperature in the working area is high, adjust the height adjustment to decrease the distance between the air guide and the filter, increase thermal resistance, and lower the temperature in the working area.

[0095] The main function of the height adjustment component is to adjust the distance between the air guide and the filter. Its specific structure can also be found in other existing structures, such as those using compression springs or intelligent lifting systems.

[0096] Preferably, the height adjustment component includes: a plurality of adjustment bolts 21; each adjustment bolt 21 includes a bolt rod and a nut; the bolt rod passes through the air guide and the nut respectively and is connected to the filter screen; the nut abuts against the air guide.

[0097] Height adjustment using adjusting bolts 21 is not only simple to operate but also adaptable to various occasions and different height requirements. During height adjustment, the distance between the air guide and the filter screen is adjusted by changing the position of the air guide on the bolt rod. In this embodiment, four adjusting bolts 21 are provided, located at the four corners of the adjusting plate A12. This facilitates height adjustment and better supports the air guide above the filter screen, improving its stability. To adjust the height, loosen the nut on the bolt rod, then adjust the distance between the adjusting plate A12 and the filter screen. After adjusting the distance, tighten the nut until it abuts against the adjusting plate A12, preventing it from slipping off the bolt rod. The height adjustment is then complete. To further stabilize the adjusting plate A12 on the bolt rod, another nut can be added to abut against it, fixing the adjusting plate A12 between the two nuts on the bolt rod, thus enhancing its stability.

[0098] Preferably, the air guide is equipped with several temperature sensors.

[0099] The temperature sensors are characterized by high accuracy and reliability. Distributing several temperature sensors across different areas of the air guide allows operators to monitor the temperature distribution in different areas of the coating oven in real time. Specifically, the temperature sensors are detachably mounted on the adjustment plate A12 and are electrically connected to the control system. A human-machine interface is provided on the temperature sensors, allowing operators to set relevant parameters. When the temperature difference between the local area and the overall average temperature of the coating oven exceeds 3 degrees Celsius (i.e., the temperature sensor detects a temperature uniformity exceeding ±3 degrees Celsius), it triggers an alarm in the control system, indicating the need for adjustment. Operators can then make timely adjustments based on the feedback, improving the convenience and accuracy of temperature adjustment.

[0100] This embodiment also provides a coating oven, including a coating oven temperature uniformity adjustment component as described above. The coating oven structure does not require redesign; only the adjustment component of this application needs to be added above the filter screen. This not only facilitates temperature uniformity adjustment of the coating oven, but also provides the air guide with a certain load-bearing capacity, protecting the filter screen from damage by sudden drops or falling plates, and allowing personnel easy access for oven maintenance.

[0101] It is understood that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that, for those skilled in the art, without departing from the concept of this application, the above technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of this application should fall within the scope of the claims of this application.
