Description

Technical Field

[0001] This utility model relates to the field of wheel hub drying, specifically a drying device for wheel hub processing that provides uniform drying. Background Technology

[0002] Wheel drying refers to the process of thoroughly removing moisture, cleaning fluid, degreasing agent, or solvents from electrophoretic paint from the surface and interior of the wheel hub during the manufacturing or surface treatment process, through heating and air circulation.

[0003] When wheel hubs are vertically suspended and multiple wheel hubs are suspended side by side and densely on the conveyor line, hot air is blown out from inside the drying equipment. Due to the complex structure of the wheel hub itself, with features such as multiple spokes, curved surfaces and deep cavities, the airflow is easily blocked by the outer surface of the wheel hub when it passes through. This causes the hot air to be unable to effectively reach the inner surface of the wheel hub, the back of the spokes and the central area, forming a drying dead zone. Moisture cannot be discharged in time, resulting in moisture residue and incomplete drying, which requires extending the drying time. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, when wheel hubs are vertically suspended and multiple wheel hubs are densely suspended side by side on the conveyor line, hot air is blown out from inside the drying equipment. Due to the complex structure of the wheel hub itself, with features such as multiple spokes, curved surfaces, and deep cavities, the airflow is easily blocked by the outer surface of the wheel hub when passing through, causing the hot air to be unable to effectively reach the inner surface of the wheel hub, the back of the spokes, and the central area, forming drying dead zones. Moisture cannot be discharged in time, resulting in moisture residue and incomplete drying, which leads to the problem of needing to extend the drying time. This utility model proposes a drying equipment for wheel hub processing that achieves uniform drying.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a drying equipment for uniformly drying wheel hub processing, including a drying equipment body, a conveying device fixedly connected to the inner wall of the drying equipment body, a suspension device slidably connected to the inner wall of the conveying device, and a wrapping drying mechanism provided on the inner wall of the drying equipment body, the number of the wrapping drying mechanisms being two. The package drying mechanism includes two fans, each with its outlet end fixedly connected to a telescopic pipe. A square box is located within the inner cavity of the drying equipment body. One end of each telescopic pipe is fixedly connected to the inner wall of the square box. Heating wires are fixedly connected to the inner wall of the square box, which has openings. A honeycomb baffle plate is fixedly connected to the inner wall of the square box. A mounting plate is fixedly connected to one side of the honeycomb baffle plate. A nozzle is rotatably connected to the inner wall of the mounting plate via a rotary joint. Several nozzles are present.

[0006] Preferably, a motor is fixedly connected to one side of the drying equipment body, and a positive and negative lead screw is rotatably connected to the inner wall of the drying equipment body. The output end of the motor is fixedly connected to one end of the positive and negative lead screw, and the surface of the positive and negative lead screw is threadedly connected to the inner wall of the square box.

[0007] Preferably, the inner wall of the drying equipment body is fixedly connected with two sliding rods, and the surfaces of the two sliding rods are slidably connected to the inner wall of the square box.

[0008] Preferably, gears are fixedly connected to the surfaces of several nozzles, and a rack is provided on one side of the mounting plate. There are four racks, and the surfaces of the gears mesh with the surfaces of the racks.

[0009] Preferably, a connecting plate is fixedly connected to one side of each of the four racks, and one end of the connecting plate extends through the inner wall of the square box and outwards.

[0010] Preferably, an electric telescopic rod is fixedly connected to the top of the square box, and the telescopic end of the electric telescopic rod is fixedly connected to one side of the connecting plate.

[0011] Preferably, a dovetail block is fixedly connected to one side of each of the four racks, and a dovetail groove is provided on the inner wall of the mounting plate. There are four dovetail grooves, and the surface of the dovetail block is in contact with the inner wall of the dovetail groove.

[0012] The advantages of this utility model are: This invention features a wrapping drying mechanism. When the wheel hub enters the drying device via the suspended conveyor line, two square boxes move towards each other, completely enclosing the suspended wheel hub to form a partially sealed drying chamber. This avoids the significant heat loss caused by prolonged openness in traditional channel-type equipment. Hot air is generated by heating the air with heating wires. The hot air enters the honeycomb guide plate through holes, evenly filling the entire inner cavity of the square boxes. Under the positive pressure created by continuous airflow, it naturally flows into the rotatable nozzles and is sprayed out. This wrapping seal of the wheel hub reduces heat loss, improves hot air utilization efficiency, and lowers energy consumption. Simultaneously, the nozzles can be rotated to adjust the airflow angle, allowing hot air to blow onto the wheel hub surface from multiple directions, effectively penetrating complex structural areas such as spoke gaps, inner cavities, and the back, enhancing the drying coverage and airflow penetration, and eliminating drying dead zones. By adjusting the closing distance between the two square boxes, it can accommodate wheel hub models of different diameters and structures, improving adaptability to mixed-product production lines.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a drying apparatus for uniformly drying wheel hubs. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A drying device for uniformly drying wheel hub processing includes a drying device body 1, a conveying device 3 fixedly connected to the inner wall of the drying device body 1, a suspension device 4 slidably connected to the inner wall of the conveying device 3, and a wrapping drying mechanism 2 provided on the inner wall of the drying device body 1, the number of wrapping drying mechanisms 2 being two. The package drying mechanism 2 includes two fans 201, which are fixedly connected to one side of the drying equipment body 1. The outlet ends of both fans 201 are fixedly connected to telescopic pipes 202. A square box 203 is installed inside the drying equipment body 1. One end of each of the two telescopic pipes 202 is fixedly connected to the inner wall of the square box 203. Heating wires 204 are fixedly connected to the inner wall of the square box 203. Holes 205 are formed in the inner wall of the square box 203. A honeycomb guide plate 208 is fixedly connected to the inner wall of the square box 203. A mounting plate 207 is fixedly connected to one side of the honeycomb guide plate 208. Spray nozzles 206 are rotatably connected to the inner wall of the mounting plate 207 via a rotary joint. Several spray nozzles 206 are present. By setting up the package drying mechanism 2, when the wheel hub enters the drying equipment body along the suspended conveyor line... Two square boxes 203 move towards each other, completely enclosing the suspended wheel hub inside to form a partially enclosed drying chamber. Hot air is generated by heating the air with heating wires 204. The hot air enters the honeycomb guide plate 208 through the holes 205, evenly filling the entire inner cavity of the square box 203. Under the positive pressure generated by continuous air supply, it naturally flows into the rotatable nozzle 206 and is sprayed out. By enclosing and sealing the wheel hub, heat loss is reduced, the efficiency of hot air utilization is improved, and energy consumption is reduced. At the same time, the nozzle 206 can be rotated to adjust the air outlet angle, so that the hot air blows on the surface of the wheel hub from multiple directions, effectively penetrating complex areas such as spoke gaps, inner cavity, and back, enhancing the drying coverage and airflow penetration, and eliminating drying dead corners. By adjusting the closing distance of the two square boxes 203, it can be adapted to wheel hub models with different diameters and structures.

[0018] Reference Figure 2 A motor 5 is fixedly connected to one side of the drying equipment body 1, and a positive and negative screw 6 is rotatably connected to the inner wall of the drying equipment body 1. The output end of the motor 5 is fixedly connected to one end of the positive and negative screw 6. The surface of the positive and negative screw 6 is threadedly connected to the inner wall of the square box 203. Through the setting of the motor 5, the motor 5 can provide driving force to the positive and negative screw 6, so that the positive and negative screw 6 rotates and drives the two square boxes 203 to move towards or in opposite directions to realize the opening and closing action. The closing distance between the two square boxes 203 can be adjusted according to the size of the wheel hub to adapt to different wheel hub models. Reference Figure 3The inner wall of the drying equipment body 1 is fixedly connected with two slide rods 7. The surfaces of the two slide rods 7 are slidably connected to the inner wall of the square box 203. By setting the slide rods 7, a stable linear guide can be provided for the two moving square boxes 203, constraining the degree of freedom of movement, preventing the two square boxes 203 from deflecting or rotating due to uneven force during the transmission along the positive and negative lead screws 6, and ensuring that the two square boxes 203 always remain parallel. Reference Figure 6 A number of nozzles 206 are fixedly connected to gears 12. A rack 13 is provided on one side of the mounting plate 207. There are four racks 13. The surfaces of the gears 12 and the racks 13 mesh. Through the arrangement of gears 12 and racks 13, the movement of racks 13 can drive gears 12 to rotate. Gears 12 drive nozzles 206 to rotate, so that nozzles 206 rotate continuously within a set angle range, changing the blowing direction of hot air and realizing dynamic adjustment of hot air outlet angle. Reference Figure 6 A connecting plate 9 is fixedly connected to one side of each of the four racks 13. One end of the connecting plate 9 penetrates the inner wall of the square box 203 and extends to the outside. The four racks 13 can be connected by the connecting plate 9 to ensure the synchronicity of the movement of the four racks 13. Reference Figure 6 An electric telescopic rod 8 is fixedly connected to the top of the square box 203. The telescopic end of the electric telescopic rod 8 is fixedly connected to one side of the connecting plate 9. The electric telescopic rod 8 provides driving force to the rack 13, which drives the connecting rod to move linearly, thereby driving the four racks 13 to move synchronously, thereby driving the gear 12 to rotate, and realizing the rotation of the nozzle 206. Reference Figure 6 Each of the four racks 13 has a dovetail block 11 fixedly connected to one side. The inner wall of the mounting plate 207 has a dovetail groove 10. There are four dovetail grooves 10. The surface of the dovetail block 11 contacts the inner wall of the dovetail groove 10. Through the setting of the dovetail block 11 and the dovetail groove 10, the racks 13 can be guided and limited, so that the racks 13 can move along the preset path and prevent the racks 13 from deviating during the movement.

[0019] Working Principle: The drying equipment body 1 sends air into the heating zone, where it is heated by the heating elements and then blown out through a fixed air duct. Convection heat transfer evaporates the moisture on the surface of the wheel hub. The automatic conveying device 3 typically uses a chain conveying system, consisting of a drive station, tensioning device, track, and traction chain. The drive unit rotates the drive wheel, and the traction chain runs continuously or in steps along the fixed track. The suspension device 4 is connected to the chain, and its surface is equipped with hanging rods. After the wheel hub is manually suspended on the hanging rods, it moves along the conveying track with the suspension device 4, sequentially conveying the wheel hub to cleaning, drying, and painting stations. After completing the corresponding treatment in each process area, it continues forward, achieving full automation throughout the process. The automated flow, being existing technology, will not be elaborated further. After the wheel hub enters the drying unit body via the conveyor 3, the user can start the motor 5 via an external control switch. The motor 5 is powered by an external power supply. The output of the motor 5 drives the positive and negative lead screws 6 to rotate. The rotation of the lead screws 6 drives the two square boxes 203 to move towards each other along the guide rod 7. The two square boxes 203 close together, enclosing the suspended wheel hub and forming a partially enclosed drying chamber. After the chamber closes, the user can start the fan 201 via an external control switch. The fan 201 is powered by an external power supply. The air inlet of the fan 201 draws in outside air, which is then discharged from the fan 201. Air is discharged from the outlet and injected into the square box 203 through the telescopic pipe 202. The heating wire 204 is powered by an external power supply and is electrically connected to the external power supply. The external power supply heats the heating wire 204, which in turn heats the injected air. As hot air continues to flow in, it enters the honeycomb guide plate 208 through the holes 205 in the square box 203. After being rectified and pressure-equalized by the honeycomb guide plate 208, the hot air evenly fills the inner cavity and flows into the nozzle 206 connected to the guide plate under positive pressure. It is then sprayed out through the nozzle 206. The electric telescopic rod 8 is then activated by the external power supply, and the telescopic end of the electric telescopic rod 8 pushes... The moving connecting plate 9 moves linearly, and the connecting rod drives the four racks 13 connected through the connecting plate 9 to move synchronously. The racks 13 mesh with the gears 12, causing the gears 12 fixed on the surface of the nozzle 206 to rotate. The nozzle 206 is rotatably connected to the mounting plate 207 through a rotary joint. By adjusting the angle of the nozzle 206, hot air is blown on the surface of the hub in multiple directions. The hot air circulates continuously in the enclosed space, penetrating complex areas such as the gaps between the hub spokes, the inner curved surface, and the deep central cavity, achieving all-round, no-dead-angle drying. After drying is completed, the electric telescopic rod 8 retracts, the nozzle 206 resets, and the output end of the motor 5 reverses to make the two square boxes 203 return to their original positions. The hub moves out with the conveying device 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
