Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint baking equipment technology, and in particular to a paint baking and drying device. Background Technology
[0002] Paint drying equipment is a key piece of equipment in industrial coating processes, and its technological background involves multiple fields such as materials science, thermodynamics, and automation control. Currently, paint drying equipment is widely used in automobile manufacturing, furniture, home appliances, aerospace, and metal products industries, requiring the dried coating to possess properties such as high gloss, wear resistance, and corrosion resistance. Its core requirements are high efficiency and energy saving, temperature uniformity, environmentally friendly emissions (VOCs treatment), stable drying quality, and automated control. Existing paint drying equipment is mainly classified according to drying methods into hot air circulation drying equipment, infrared radiation drying equipment, ultraviolet curing drying equipment, microwave drying equipment, and high infrared drying equipment. Among them, hot air circulation drying equipment heats air and circulates it through convection, utilizing heat conduction and convection to transfer heat. It is widely used in mass production conditions and has relatively low cost.
[0003] However, existing hot air circulating drying equipment lacks a mechanism for the directional collection of low-temperature hot air after heat exchange, which allows impurities, paint mist, solvents and other substances that may be carried in the low-temperature hot air to escape at will, thereby affecting the quality of the paint film on the workpiece and easily causing pollution to the production site. Utility Model Content
[0004] Therefore, it is necessary to provide a paint drying device that addresses the technical problem of insufficient exhaust gas treatment in existing paint drying devices.
[0005] A paint drying device includes a drying chamber, a hot air mechanism, and a conveying mechanism. The drying chamber is located on top of the conveying mechanism, and the hot air mechanism is located on top of the drying chamber.
[0006] The hot air mechanism includes a heating module, a working module, and an exhaust module. The heating module is located at one end of the top of the drying chamber, the exhaust module is located at the other end of the top of the drying chamber, and the working module is located between the heating module and the exhaust module, and the working module is connected to the interior of the drying chamber. Based on this, the heating module, the working module, and the exhaust module are connected in sequence.
[0007] The exhaust module includes an exhaust hood and an exhaust fan. The low-temperature hot air exhaust end of the exhaust hood corresponding to the working module is connected to one end of the top of the drying chamber; the exhaust fan is located inside the exhaust hood.
[0008] In one embodiment, the exhaust hood is provided with a first exhaust port and a second exhaust port, the first exhaust port being located at the bottom of the exhaust hood; the second exhaust port being located at the top of the exhaust hood corresponding to the first exhaust port.
[0009] In one embodiment, the input side of the exhaust fan is matched with the first exhaust port, and the output side of the exhaust fan is matched with the second exhaust port.
[0010] In one embodiment, the above-mentioned working module includes a first fan, a second fan, and an air guide structure, the air guide structure being disposed at the top of the drying chamber; the first fan and the second fan are arranged sequentially along the hot air flow direction of the drying chamber; wherein, the first fan is disposed on the adjacent side of the heating module, and the second fan is disposed on the adjacent side of the exhaust module.
[0011] In one embodiment, the air guiding structure includes a first partition, a first end plate, and a second end plate; the first partition is disposed at the top of the drying chamber; the first end plate is disposed at one end of the top of the drying chamber corresponding to the heating module; and the second end plate is disposed at the other end of the top of the drying chamber corresponding to the exhaust module.
[0012] In one embodiment, the first partition is provided with a first vent and a second vent, and the first vent and the second vent are respectively matched with the first fan and the second fan.

[0015] In one embodiment, the second partition is provided with a plurality of ventilation holes at both ends, and the two ends of the first air guide plate extend to the ventilation holes at both ends of the second partition.
[0016] In one embodiment, the third partition is provided with a plurality of ventilation holes at both ends, and the two ends of the second air guide plate extend to the ventilation holes at both ends of the third partition.
[0017] The aforementioned paint baking and drying device heats the airflow entering from the outside to a preset temperature via a heating module. High-temperature hot air is input to one end of the working module and blown into the drying chamber. Low-temperature hot air that has completed heat exchange within the drying chamber flows back to the working module and is output from the other end of the working module to the exhaust module. The exhaust module then discharges the low-temperature hot air to the outside of the paint baking and drying device, thus completing the workpiece paint baking and drying process.

[0026] Please see Figures 1 to 2This utility model discloses a paint baking and drying device 1, which includes a drying chamber 10, a hot air mechanism, and a conveying mechanism 20. The drying chamber 10 is located on top of the conveying mechanism 20, and the hot air mechanism is located on top of the drying chamber 10. Thus, the workpiece to be painted is conveyed through the drying chamber 10 via the conveying mechanism 20, and the hot air mechanism inputs hot air at a preset temperature into the drying chamber 10, thereby completing the paint baking and drying process as the workpiece passes through the drying chamber 10. Specifically, the hot air mechanism includes a heating module 30, a working module 40, and an exhaust module 50. The heating module 30 is located at one end of the top of the drying chamber 10, the exhaust module 50 is located at the other end of the top of the drying chamber 10, and the working module 40 is located between the heating module 30 and the exhaust module 50, and the working module 40 is connected to the interior of the drying chamber 10. Therefore, the heating module 30, the working module 40, and the exhaust module 50 are sequentially connected, thus connecting one end of the heating module 30 and the working module 40, the drying chamber 10, and the working module 50. The other end of module 40 and exhaust module 50 can sequentially form a heating air duct; wherein, heating module 30 can heat the airflow entering from the outside to a preset temperature, high-temperature hot air is input to one end of working module 40 and blown into drying chamber 10, low-temperature hot air that has completed heat exchange in drying chamber 10 flows back to working module 40 and is output from the other end of working module 40 to exhaust module 50, and then exhaust module 50 discharges low-temperature hot air to the outside of paint baking drying device 1, thereby completing the workpiece paint baking drying process. More specifically, the exhaust module 50 includes an exhaust hood 51 and an exhaust fan (not shown). The exhaust hood 51 is connected to one end of the top of the drying chamber 10 corresponding to the low-temperature hot air exhaust end of the working module 40. The exhaust fan is located inside the exhaust hood 51. The low-temperature hot air discharged from the working module 40 and the drying chamber 10 can be input into the exhaust hood 51 through the bottom of the exhaust hood 51, and then blown out from the top of the exhaust hood 51 by the exhaust fan. This removes impurities, paint mist, solvent vapor and hot air from the low-temperature hot air in a timely manner, thereby ensuring the quality of the paint film on the surface of the workpiece.
[0027] Furthermore, in one embodiment, the exhaust hood 51 is provided with a first exhaust port a and a second exhaust port b. The first exhaust port a is located at the bottom of the exhaust hood 51 for inputting low-temperature hot air; the second exhaust port b is located at the top of the exhaust hood 51 corresponding to the first exhaust port a for outputting low-temperature hot air. Specifically, the input side of the exhaust fan corresponds to the first exhaust port a, and the output side of the exhaust fan corresponds to the second exhaust port b. In addition, the second exhaust port b can be used to connect to an external waste gas collection device, so that the discharged low-temperature hot air can be directly transported to the waste gas treatment equipment for treatment and recycling.
[0028] Furthermore, the working module 40 includes a first fan 41, a second fan 42, and an air guide structure, with the air guide structure located at the top of the drying chamber 10. The first fan 41 and the second fan 42 are arranged sequentially along the hot air flow direction of the drying chamber 10. The first fan 41 is located adjacent to the heating module 30, and the second fan 42 is located adjacent to the exhaust module 50. Based on this structure, the heating module 30 delivers high-temperature hot air to the first fan 41 via the air guide structure. The first fan 41 then blows the high-temperature hot air into the drying chamber 10 through the air guide structure to perform baking and drying of the workpieces. The low-temperature hot air, after heat exchange, is extracted from the drying chamber 10 by the second fan 42 through the air guide structure and delivered to the exhaust module 50. The exhaust module 50 then removes the low-temperature hot air.
[0029] Furthermore, the air guiding structure includes a first partition 43, a first end plate 44, and a second end plate 45. The first partition 43 is disposed at the top of the drying chamber 10 to separate the working module 40 from the drying chamber 10. The first end plate 44 is disposed at one end of the top of the drying chamber 10 corresponding to the heating module 30. The second end plate 45 is disposed at the other end of the top of the drying chamber 10 corresponding to the exhaust module 50, thereby forming a relatively independent air guiding space. Specifically, the first partition 43 is provided with a first vent d and a second vent e, which correspond one-to-one with the first fan 41 and the second fan 42, respectively. Thus, the first fan 41 is connected to the drying chamber 10 through the first vent d, and the second fan 42 is connected to the drying chamber 10 through the second vent e.
[0030] Furthermore, the air guiding structure also includes a second partition 46 and a third partition 47; the second partition 46 is disposed between the first end plate 44 and the first fan 41, and the third partition 47 is disposed between the second end plate 45 and the second fan 42. Thus, an air inlet buffer zone is formed between the second partition 46 and the first end plate 44, and an air outlet buffer zone is formed between the third partition 47 and the second end plate 45, so as to prevent high-temperature hot air from convecting inside the working module 40 and directly escaping to the outside of the drying chamber 10.
[0031] Furthermore, the air guiding structure also includes a first air guide plate 48a, a second air guide plate 48b, and a third air guide plate 48c. The first air guide plate 48a is disposed between the second partition 46 and the first fan 41, the second air guide plate 48b is disposed between the third partition 47 and the second fan 42, and the third air guide plate 48c is disposed between the first fan 41 and the second fan 42. Based on the above structure, the first air guide plate 48a, in conjunction with the third air guide plate 48c, guides the high-temperature hot air delivered to the first fan 41 to form an air vortex, which facilitates the high-temperature hot air entering the drying chamber 10 through the first vent d; the second air guide plate 48b, in conjunction with the third air guide plate 48c, guides the low-temperature hot air delivered to the second fan 42 to form an air vortex, which facilitates the low-temperature hot air being discharged from the drying chamber 10 through the second vent e.
[0032] Furthermore, the second partition 46 is provided with several ventilation holes c at both ends, and the two ends of the first air guide plate 48a extend to the ventilation holes c at both ends of the second partition 46 to guide the air intake.
[0033] Furthermore, several ventilation holes c are provided at both ends of the third partition 47, and both ends of the second air guide plate 48b extend to the ventilation holes c at both ends of the third partition 47 to guide the incoming air.
[0034] In summary, the paint baking and drying device disclosed in this utility model heats the airflow entering the heating module from the outside to a preset temperature through the heating module. The high-temperature hot air is input to one end of the working module and blown into the drying chamber. The low-temperature hot air that has completed heat exchange in the drying chamber flows back to the working module and is output from the other end of the working module to the exhaust module. Then, the exhaust module discharges the low-temperature hot air to the outside of the paint baking and drying device, thereby completing the paint baking and drying process of the workpiece. Specifically, the low-temperature hot air discharge end of the exhaust hood corresponding to the working module is connected to one end of the top of the drying chamber; the exhaust fan is set inside the exhaust hood. The low-temperature hot air discharged from the working module and the drying chamber can be input into the exhaust hood through the bottom of the exhaust hood, and then blown out from the top of the exhaust hood by the exhaust fan, thereby timely discharging impurities, paint mist, solvent vapors and hot air in the low-temperature hot air, thus ensuring the quality of the paint film on the surface of the workpiece.
[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
