Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 This utility model provides an embodiment of a rapid drying device for spray painting automotive frame rivets, comprising a housing 1, an organic base 17 fixedly connected to the left side of the housing 1, a top cover 16 threadedly connected to the right side of the housing 1, an air inlet pipe 14 threadedly connected to the outer right side of the housing 1, a fixing groove 10 formed on the inner wall of the housing 1, an infrared radiator 7 fixedly connected to the outer wall of the fixing groove 10, a sleeve 8 provided outside the infrared radiator 7, and a heating wire 9 fixedly installed inside the sleeve 8. The inner wall of the top cover 16 is fixedly connected to... A motor 3 is provided on the left side of the reflector plate 11 and the top cover 16. A rotating rod 4 is fixedly connected to the output end of the motor 3. A turntable 5 is fixedly connected to the right side of the rotating rod 4. A rotating blade 6 is fixedly connected to the outer wall of the rotating rod 4. A dehumidifier 13 is threadedly connected to the upper middle part of the outer wall of the air inlet pipe 14. A heater 15 is threadedly connected to the middle part of the outer wall of the air inlet pipe 14. A blower 12 is fixedly connected to the rear side of the heater 15. A purification structure 2 is provided on the outer wall of the bottom 17. The purification structure 2 can be used to treat the exhaust gas of the casing 1.

[0034] Specifically, the housing 1 is made of stainless steel sheet, and the inner wall is treated to reduce reflection loss. The two ends of the housing 1 are connected to the bottom 17 and the top cover 16, and a sealing ring 202 is installed to ensure airtightness. The bottom 17, as the foundation of the device, is made of cast iron material, and multiple bolts are set at the bottom to fix the air inlet of the purification structure 2 on the outside. The top cover 16 is fixed to the right side of the housing 1 by a threaded connection, which facilitates quick disassembly and removal of rivets. A reflector plate 11 is set on the inner wall of the top cover 16 to reflect the heat emitted by the infrared radiator 7 back to the drying area. Multiple fixing grooves 10 are evenly opened along the axial direction on the inner wall of the housing 1. The infrared radiator 7 can directly penetrate the coating on the surface of the rivets to accelerate the drying efficiency. The sleeve 8 is fitted on the outside of the infrared radiator 7, and the inner wall is wrapped with heating wire 9 to increase the heating rate of the coating. The air inlet pipe 14 is made of stainless steel pipe, and one end is connected to the housing by a thread. On the lower right side of body 1, a dehumidifier 13 and a heater 15 are connected in series at the other end. The dehumidifier 13 is a rotary dehumidifier, which can reduce the humidity of the incoming air. The heater 15 can heat the air. The blower 12 and the heater 15 start and stop in tandem to ensure that hot air enters the housing 1. The motor 3 is installed on the motor base on the left side of the top cover 16. The surface of the rotating rod 4 is treated with rust prevention. The turntable 5 is fixed to the end of the rotating rod 4 and rotates with the rotating rod 4. The rotating blades 6 are evenly distributed with multiple sets of arc-shaped blades along the turntable 5. When rotating, the airflow is formed, which guides the hot air entering from the right side to the left side to avoid uneven drying. When heating is started, the dehumidifier 13 and the blower 12 are turned on first, and then the heater 15 and the infrared radiator 7 are turned on. The motor 3 starts, and the rotating blades 6 drive the airflow to circulate. When drying is finished, the infrared radiator 7 and the heating wire 9 stop working and no longer heat.

[0035] Please see the appendix Figure 1 Appendix Figure 6 and attached Figure 7 The purification structure 2 includes an air intake hood 201, a sealing ring 202 is fixedly connected inside the air intake hood 201, an air intake pipe 204 is threadedly connected to the outer wall of the sealing ring 202, a manual valve 203 is rotatably connected to the top of the air intake pipe 204, a vacuum pump 205 is fixedly installed at the bottom of the air intake pipe 204, a gas supply pipe 211 is threadedly connected to the left side of the vacuum pump 205, a pressure gauge 206 is fixedly connected to the top of the vacuum pump 205, a decontamination device 207 is fixedly installed at the left end of the gas supply pipe 211, a hollow box 208 is provided outside the decontamination device 207, a sliding groove 209 is fixedly connected to the bottom of the hollow box 208, and a filter plate 210 is slidably connected to the outer wall of the sliding groove 209.

[0036] Specifically, the purification structure 2, as the core module for waste gas treatment, targets the volatiles and small amount of dust generated during the drying process inside the casing 1. The exhaust ports of the suction hood 201 and the machine base 17 are connected, and with the negative pressure generated by the vacuum pump 205, the waste gas in the casing 1 is collected and discharged, preventing leakage. The sealing ring 202 is embedded between the suction hood 201 and the machine base 17. Compression of the sealing ring 202 maintains a stable negative pressure environment. One end of the suction pipe 204 is threaded to the lower opening of the suction hood 201, and the other end is connected in series with a manual valve 203. This valve is used to cut off the airflow and adjust the waste gas flow during maintenance. The air inlet is connected to the suction pipe 204. The vacuum pump 205 can create a stable negative pressure at the suction hood 201 to ensure that the exhaust gas flows at a uniform speed in the pipeline. The pressure gauge 206 is installed at the front end of the air inlet of the vacuum pump 205 to monitor the negative pressure value in the suction pipe 204 in real time. When the pressure is abnormal, it needs to be repaired in time. The two ends of the air supply pipe 211 are connected to the suction pipe 204 and the decontamination equipment 207 respectively. The decontamination equipment 207 has a built-in filter plate 210 installed inside the hollow box 208. The hollow box 208 serves as a protective shell for the decontamination equipment 207. The bottom is provided with a sliding groove 209 to allow for flexible movement and maintenance. The filter plate 210 is a stainless steel mesh plate and can be manually pulled out and replaced.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 A control box 18 is fixedly connected to the outside of the housing 1. A rotating rod 19 is threadedly connected to the outer wall of the turntable 5. A connector 20 is provided at the left end of the rotating rod 19. A connecting groove 21 is opened on the outer wall of the turntable 5. A wheel axle 28 is fixedly connected to the bottom of the housing 1. A universal wheel 27 is fixedly connected to the bottom of the wheel axle 28.

[0038] Specifically, the control box 18 adopts a wall-mounted design, fixed to the left outer wall of the housing 1. After startup, it detects the temperature inside the housing 1, first activating the heating wire 9 and heater 15 for preheating, then turning on the infrared radiator 7 and rotating blade 6. The rotating rod 19 and the turntable 5 work together to avoid uneven drying in certain areas. The rotating rod 19 is made of stainless steel round rod, evenly distributed along the outer wall of the turntable 5 and fixed to the turntable 5. The connector 20 is detachable, sleeved on the left end of the rotating rod 19. The rivets fully contact the hot air and infrared radiation, improving drying uniformity. It can be replaced by hand after wear, resulting in low maintenance costs. The connecting groove 21 is the connection point between the turntable 5 and the rotating rod 19. Distributed along turntable 5, connecting groove 21 can withstand long-term baking of infrared radiator 7, preventing coating discoloration due to local overheating at the contact point between rivets and turntable 5. The length of axle 28 matches the width of housing 1, ensuring that axle 28 can bear the total weight of housing 1 and internal components. Casters 27 have good shock absorption performance, which can prevent internal components of housing 1 from loosening due to bumps during movement, ensuring that the device does not shift during drying operations. The combination of axle 28 and casters 27 allows housing 1 to adapt to long-term operation at fixed workstations and can be quickly transferred to other painting lines for production, making it especially suitable for multi-variety, small-batch automotive parts production.

[0039] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The dehumidifier 13 has a base plate 24 at the bottom and a handle 29 fixedly connected to the top of the dehumidifier 13. A fixing plate 22 is fixedly connected to the outer wall of the rotating rod 19, and a washer 23 is movably connected to the outer wall of the fixing plate 22. A support column 25 is provided at the top of the base plate 24, and a load-bearing plate 26 is fixedly connected to the top of the support column 25.

[0040] Specifically, the dehumidifier 13, as a device for controlling the humidity of the incoming air, features a base plate 24 at the bottom and a handle 29 at the top. These features ensure the stability of the equipment's operation and improve ease of maintenance. The base plate 24 is fixed to the ground to prevent loosening due to vibration during operation. A support column 25, made of steel pipe, is welded vertically along the base plate 24, with the load-bearing plate 26 welded to the top. The load-bearing plate 26 is made of stainless steel, and the dehumidifier 13 is fixed to it. The handle 29, also made of stainless steel pipe, is fixed at both ends to the top cover of the dehumidifier 13. The handle 29 is designed at a suitable height, allowing the operator to grip it naturally while standing, enabling a single person to lift the dehumidifier 13. The design facilitates regular relocation and cleaning of the internal filter. The fixing plate 22 and the washer 23 work together. The fixing plate 22 is a circular stainless steel mesh plate, which is fixed to the outer wall of the rotating rod 19 by bolts to ensure that the rivets will not fall off after being inserted vertically. It rotates synchronously with the rotating rod 19. The washer 23 can withstand the drying environment inside the housing 1. When replacing, it can be pulled out by hand from the mesh, making maintenance convenient. When the position of the device needs to be adjusted, the housing 1 can be moved on the workshop floor. The base plate 24 and the support column 25 form a stable load-bearing frame. When the load-bearing plate 26 needs maintenance, the operator holds the handle 29 to move the dehumidifier 13 off the support column 25, improving the efficiency of filter cleaning.

[0041] Working principle: When rivets need to be dried, the operator first opens the top cover 16, takes out the rotating rod 19, places the rivet into the fixing plate 22 and fixes it with the washer 23. Then, the rotating rod 19 with the rivet installed is fixed to the turntable 5 through the connection of the connector 20 and the connecting groove 21. After closing the top cover 16, the infrared radiator 7 is started through the control box 18. The infrared radiator 7 irradiates infrared rays onto the reflector plate 11. After being reflected by the reflector plate 11, the entire interior of the housing 1 is heated. At the same time, the air enters the dehumidifier 13 for dehumidification and is then sent to the heater 15 for heating. The blower 12 sends the air heated by the heater 15 into the housing 1 through the air inlet pipe 14. This utilizes... Infrared radiation acts directly on the coating molecules, causing them to vibrate and generate heat. This eliminates the need to heat the air, resulting in faster heating. The outlet of the air inlet pipe 14 is connected to the housing 1, which reduces heat loss during the transmission of hot air. The start of the control box 18 also drives the operation of the motor 3. The operation of the motor 3 causes the rotating rod 4 connected to the output end of the motor 3 to rotate, which in turn drives the rotation of the turntable 5. The outer wall of the rotating rod 4 is fixedly connected to the rotating blade 6, so the rotation of the rotating rod 4 will drive the rotation of the rotating blade 6, causing the hot air inside the housing 1 to circulate and be evenly distributed on the rivet surface to accelerate the drying process. After drying is completed, the top cover 16 is opened, and the rotating rod 19 is taken out to collect the rivets of the fixing plate 22.

[0042] During waste gas treatment, after the vacuum pump 205 is started, the waste gas is extracted from the housing 1 through the suction pipe 204. During the extraction process, the suction hood 201 will collect the waste gas inside to prevent it from overflowing. The manual valve 203 controls the extraction intensity. The extracted waste gas is transported into the decontamination equipment 207 through the gas delivery pipe 211. After the waste gas is adsorbed by the filter plate 210, the impurities are filtered out. Then the purified gas is discharged. During the purification process, the pressure gauge 206 will detect the gas volume in the housing 1. After filtration is completed, the vacuum pump 205 is turned off. The filter plate 210 can be slid out through the slide groove 209 at the bottom of the hollow box 208 for regular cleaning to ensure the effect of subsequent use.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
