[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As attached Figure 1 -Appendix Figure 6As shown, a wheel hub spraying and drying device includes a drying chamber and a movable frame 5. The movable frame 5 is equipped with several mounting seats 6. The drying chamber includes a base plate 1, with side plates 2 installed on both the left and right sides of the upper part of the base plate 1. A top plate 3 is installed on the upper part of the side plates 2. A sealing door 4 is hinged to one side plate 2. A wind box 7 is installed on the inner wall of the side plate 2. Air holes 8 are opened on the wind box 7, connecting the interior of the wind box 7 to the interior of the drying chamber. The air holes 8 on the two sides of the wind box 7 are staggered vertically, with the air hole 8 on the left side of the wind box 7 located at the upper position and the air hole 8 on the right side of the wind box 7 located at the lower position, allowing the airflow inside the drying chamber to flow diagonally, enabling hot air to flow through the entire interior of the drying chamber. A rotating seat 17 is installed inside the top plate 3. A connecting hole 18 and a connecting hole 2 19 are respectively opened on the left and right sides of the rotating seat 17. The outer ends of the connecting holes 18 and 2 19 are connected to... A duct 20 is connected to the top of two air boxes 7. A rotating platform 15 is mounted on the top of the top plate 3 via a drive mechanism. A heating box 9 and a return air box 10 are mounted on the rotating platform 15. Several heating tubes 12 are installed inside the heating box 9. A connecting pipe 11 connects the return air box 10 and the heating box 9. A connecting rod 54 is connected to the lower part of the rotating platform 15. An adjusting plate 21 is connected to the lower part of the connecting rod 54. The adjusting plate 21 is rotatably mounted in the rotating seat 17. An air supply chamber 23 and a return air chamber 24 are opened inside the adjusting plate 21. A partition 22 is set between the air supply chamber 23 and the return air chamber 24. The air supply chamber 23 and the return air chamber 24 are respectively connected to the heating box 9 and the return air box 10. An air supply notch 25 and a return air notch 26 are opened on the side of the adjusting plate 21. The air supply notch 25 is connected to the air supply chamber 23, and the return air notch 26 is connected to the return air chamber 24.

[0023] When the air supply chamber 23 is connected to the connecting hole 18 through the air supply notch 25, and the return air chamber 24 is connected to the connecting hole 29 through the return air notch 26, the hot air from the heating box 9 enters the left-side air duct 20 through the air supply chamber 23, the air supply notch 25, and the connecting hole 18, and is blown out from the left-side air box 7. The hot air passes through the interior of the drying box from left to right, and then enters the right-side air box 7. The air then returns to the return air box 10 through the connecting hole 29, the return air notch 26, and the return air chamber 24, completing the air circulation.

[0024] The drive mechanism drives the rotary table 15 to rotate. The rotary table 15, via the connecting rod 54, drives the adjusting plate 21 to rotate within the rotating seat 17, thereby adjusting the positions of the air supply chamber 23 and the return air chamber 24. When the air supply chamber 23 is connected to the second connecting hole 19 through the air supply notch 25, and the return air chamber 24 is connected to the first connecting hole 18 through the return air notch 26, hot air can pass through the interior of the drying chamber from right to left, changing the direction of hot air flow. This change in the direction of hot air flow alters the heating position of the hub, resulting in more uniform heating and a better drying effect.

[0025] The drive mechanism includes a drive motor 39, which drives a drive shaft 28. A second drive pulley 40 is mounted on the drive shaft 28. A rotary table 15 is arranged around the outer periphery of the transmission belt ring 16. A transmission belt 41 connects the rotary table 15 and the second drive pulley 40. The drive motor 39 drives the drive shaft 28 to rotate, and the drive shaft 28 drives the rotary table 15 to rotate through the cooperation of the second drive pulley 40, the second transmission belt 41, and the rotary table 15. A mounting bracket 38 is connected to the top plate 3, and the drive motor 39 is mounted on the mounting bracket 38.

[0026] An air supply pump 13 and an exhaust pump 14 are installed inside the rotary table 15. The air inlet of the air supply pump 13 is connected to the heating chamber 9, and the air outlet of the air supply pump 13 is connected to the air supply chamber 23. The air inlet of the exhaust pump 14 is connected to the return air chamber 24, and the air outlet of the exhaust pump 14 is connected to the return air box 10. The air supply pump 13 pumps hot air from the heating chamber 9 into the air supply chamber 23, and the exhaust pump 14 pumps air from the return air chamber 24 into the drive pulley 40, providing the power for airflow within the drying chamber, thereby completing the air circulation.

[0027] The distance between the end of the air supply gap 25 and the end of the return air chamber 24 is greater than the diameter of the connecting hole 18 and the connecting hole 29. The width of the part of the regulating plate 21 without gaps is greater than the diameter of the connecting hole 18 and the connecting hole 29, so that this part can completely cover the connecting hole 18 or the connecting hole 29. There will be no situation where the connecting hole 18 or the connecting hole 29 is connected to the air supply gap 25 and the return air gap 26 at the same time, ensuring that the air supply and return air are staggered and will not affect each other.

[0028] The movable frame 5 includes a movable base 33, with support rods 34 connected around the upper part of the movable base 33. Several mounting plates 35 are installed between the support rods 34, and the mounting plates 35 are spaced apart vertically. Mounting seats 6 are mounted on the mounting plates 35, allowing multiple wheel hubs to be placed and dried simultaneously. The mounting plates 35 have through holes 42 for hot air circulation, ensuring that the wheel hubs on each layer are effectively dried.

[0029] Mounting base 6 includes a rotating base 43 mounted on mounting plate 35. A support plate 44 is mounted on the upper part of the rotating base 43, and a positioning pin 45 is connected to the middle of the upper part of the support plate 44. The positioning pin 45 can be inserted into the axle hole of the wheel hub for positioning. The support plate 44 can support the axle hole end of the wheel hub. A rotating shaft 46 is connected to the lower part of the support plate 44. The rotating shaft 46 is rotatably mounted in the rotating seat 43. The lower end of the rotating shaft 46 passes through the mounting plate 35 and is connected to a transmission pulley 48. A transmission belt 36 is connected between the transmission pulleys 48. A driven gear 47 is connected to the lower end of the rotating shaft 46. The drying box includes an end plate 27. A support plate 30 is connected to the inner side of the end plate 27. A transmission shaft 49 is rotatably mounted inside the support plate 30. A drive gear 51 is connected to the upper end of the transmission shaft 49. The drive gear 51 can mesh with the driven gear 47. A receiving cavity 53 is opened inside the support plate 30. The part of the transmission shaft 49 located in the receiving cavity 53 is connected to a driven pulley 50. The lower end of the drive shaft 28 extends into the end plate 27. The part of the drive shaft 28 located in the end plate 27 is connected to a drive pulley 29. A transmission belt 42 is connected between the drive pulley 29 and the driven pulley 50. The moving rack enters the drying chamber, and the driven gear 47 meshes with the drive gear 51.

[0030] When the drive motor 39 drives the drive shaft 28 to rotate, the drive shaft 28 drives the transmission shaft 49 to rotate through the cooperation of the drive pulley 29, the transmission belt 52, and the driven pulley 50. The transmission shaft 49 then drives the rotating shaft 46 to rotate through the cooperation of the drive gear 51 and the driven gear 47. The rotating shaft 46 drives the hub placed on the support plate 44 to rotate. The rotation of the hub can change the heating position of the hub, making the heating more uniform.

[0031] Each of the rotating shafts 46 has a driven gear 47 installed at its lower part. After one end of the moving frame 5 moves into the drying chamber, the driven gear 47 meshes with the drive gear 51, so there is no need to restrict the moving direction of the moving frame 5.

[0032] The drying oven includes a sealing door 4, which is located on the side away from the end plate 27. The sealing door 4 is hinged to one of the side plates 2. The bottom plate 1 is connected to a loading platform 37 at the end near the sealing door 4. The height of the loading platform 37 gradually decreases in the direction away from the bottom plate 1. The height of the end of the loading platform 37 connected to the bottom plate 1 is flush with the bottom plate 1. The movable frame can move along the upper end of the loading platform 37 and easily enter the drying oven.

[0033] Two parallel limiting strips 31 are provided on the upper part of the base plate 1. The distance between the two limiting strips 31 is slightly larger than the distance between the outer sides of the moving wheels of the moving base 33, so as to limit the position of the top plate 3 in the drying chamber and to assist in positioning the meshing of the driven gear 47 and the drive gear 51.

[0034] A guide ramp 32 is provided near the inlet of the limiting bar 31. The guide ramp 32 makes the width of the inlet of the limiting bar 31 smaller, which can guide the moving wheel of the moving base 33, so that the moving wheel can move correctly between the two limiting bars 31, and ensure that the driven gear 47 and the drive gear 51 can mesh accurately.

[0035] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
