[0026] 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 protection scope of the present utility model.

[0027] Please see Figures 1 to 4 The intelligent curing production line for electrostatic powder coating of wheel hubs in this embodiment includes a drying chamber 1. The left and right sides of the drying chamber 1 are provided with clearance grooves 2. The interior of the drying chamber 1 is rotatably connected by bearings to four rotating rods 15. A conveyor belt 16 is fitted between the outer peripheral walls of two adjacent rotating rods 15. The drying chamber 1 is provided with a flipping component for flipping the wheel hub.

[0028] The flipping assembly includes a mounting frame 6, which is placed inside the drying chamber 1. A connecting frame 9 is placed inside the drying chamber 1. Two first electric push rods 8 are fixedly installed on the inner top wall of the mounting frame 6. The output ends of the two first electric push rods 8 are fixedly connected to the connecting frame 9. The front inner wall and the back inner wall of the connecting frame 9 are rotatably connected to drive rods 21 through bearings. The drive rod 21 located on the back penetrates the connecting frame 9 and extends to its back. Mounting holes 19 are opened on opposite sides of the two drive rods 21. Second electric push rods 20 are fixedly installed inside the two mounting holes 19. The output ends of the two second electric push rods 20 are fixedly connected to clamps 10. A first motor 18 is fixedly installed on the back of the connecting frame 9. The first motor 18 and the back drive rod 21 are fixedly connected.

[0029] The drying chamber 1 is a rectangular prism with a hollow interior and a missing bottom surface. The clamping plate 10 is an arc-shaped plate. The mounting frame 6 and the connecting frame 9 are both U-shaped frames. The connecting frame 9 is located on top of the conveyor belt 16.

[0030] Specifically, when the hub is at the bottom of the connecting frame 9, the first electric push rod 8 is activated. The output end of the first electric push rod 8 drives the connecting frame 9 to move downward, so that the hub is between the two clamping plates 10. The second electric push rod 20 is activated. The output end of the second electric push rod 20 drives the clamping plate 10 to move, and the clamping plate 10 and the hub are in contact, fixing the hub and thus resetting the connecting frame 9. The first motor 18 is activated. The output shaft of the first motor 18 drives the drive rod 21 to rotate, causing the hub to flip.

[0031] It should be noted that this application can achieve synchronous operation by employing a synchronization controller or other synchronization device to ensure that the output ends of the two first electric push rods 8 and the output ends of the two second electric push rods 20 extend and retract simultaneously. These synchronization devices are common and mature in the field of electric control, and therefore will not be described in detail in the specific embodiments.

[0032] Please see Figures 1 to 4In this embodiment, the drying chamber 1 is equipped with a drying assembly for drying the wheel hub. The drying assembly includes two conveyor frames 12, which are fixedly connected inside the drying chamber 1. Each of the two conveyor frames 12 has a placement slot 13 inside, and the inner wall of each of the two conveyor frames 12 has a plurality of air outlet holes 14. The back of the drying chamber 1 is fixedly connected with two air inlet pipes 11, one end of which passes through the drying chamber 1 and the conveyor frame 12 and extends into the placement slot 13. The back of the drying chamber 1 is fixedly installed with two second motors 17. The two rotating rods 15 located in the middle pass through the drying chamber 1 and extend to its back and are fixedly connected to the output shafts of the two second motors 17 respectively.

[0033] The conveyor frame 12 is a U-shaped frame, the air inlet pipe 11 is fixedly connected to the conveyor frame 12, and the conveyor belt 16 is located inside the conveyor frame 12.

[0034] Specifically, the second motor 17 is started, and the output shaft of the second motor 17 drives the two rotating rods 15 located in the middle to rotate, causing the conveyor belt 16 to move. The external high-temperature gas enters the interior of the placement trough 13 through the air inlet pipe 11. The hub is placed on the conveyor belt 16, and the hub is moved by the conveyor belt 16. The high-temperature air passes through the air outlet 14 to dry the hub.

[0035] It should be noted that this application can ensure that the output shafts of the two second motors 17 rotate simultaneously by using a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, so they will not be described in detail in the specific embodiments. Both air inlet pipes 11 are connected to the external high-temperature gas delivery pipe.

[0036] Please see Figures 1 to 4 In this embodiment, the drying chamber 1 is provided with a drive assembly for moving the mounting frame 6. The drive assembly includes a third motor 3, which is fixedly installed on the right side of the drying chamber 1. A sliding groove 5 is provided on the inner top wall of the drying chamber 1.

A screw 4 with one end penetrating through the drying chamber 1 and extending into it is fixedly connected to the output shaft of the third motor 3. The screw 4 penetrates the sliding plate 7.

[0037] The sliding plate 7 and the sliding groove 5 are slidably connected, and the screw 4 is rotatably connected to the drying chamber 1 through the bearing. The right side of the sliding plate 7 is provided with a threaded hole, and the screw 4 passes through the threaded hole and is threadedly connected to it.

[0038] Specifically, the third motor 3 is started, and the output shaft of the third motor 3 drives the screw 4 to rotate. Through the threaded connection between the screw 4 and the sliding plate 7 and the sliding connection between the sliding plate 7 and the sliding groove 5, the screw 4 drives the mounting frame 6 to move to the right, so that the hub is located on the right conveyor belt 16.

[0039] The working principle of the above embodiments is as follows:

[0040] The second motor 17 is started, and its output shaft drives the two rotating rods 15 in the middle to rotate, causing the conveyor belt 16 to move. High-temperature gas from outside enters the placement trough 13 through the air inlet pipe 11. The hub is placed on the conveyor belt 16, which moves the hub. High-temperature air passes through the air outlet 14 to dry the hub. When the hub is at the bottom of the connecting frame 9, the first electric push rod 8 is started. The output end of the first electric push rod 8 moves the connecting frame 9 downwards, positioning the hub between the two clamping plates 10. The second electric push rod 20 is then started, and its output... The end drives the clamping plate 10 to move, and the clamping plate 10 fits against the hub to fix the hub, thereby resetting the connecting frame 9. The first motor 18 is started, and the output shaft of the first motor 18 drives the drive rod 21 to rotate, causing the hub to flip. The third motor 3 is started, and the output shaft of the third motor 3 drives the screw 4 to rotate.
