[0024] Refer to Figures 1-7, a baking paint device for the outer surface of a bearing housing, comprising a support plate 1. A box body 2 is provided on the upper surface of the support plate 1. The box body 2 is composed of an outer shell 5 and an inner shell 6, and a cavity 7 is formed between the outer shell 5 and the inner shell 6. Baking components 9 for heating the inside of the box body 2 are provided on both inner side walls of the inner shell 6. Two groups of square openings 14 are symmetrically formed at the top of the inner shell 6, and each group has multiple square openings 14. A square frame 15 is fixedly connected below each of the multiple square openings 14 by bolts. Electric fans 16 are fixedly connected in each of the multiple square frames 15 by bolts. Two first sealing covers 11 for sealing the multiple square openings 14 in the same group are provided in the cavity 7. Air inlet grilles 10 communicating with the cavity 7 are provided on the bottom inner wall of the inner shell 6. Two second sealing covers 13 for respectively sealing the air inlet grilles 10 are provided in the cavity 7. Multiple communicating components 8 for communicating the first sealing cover 11 with the second sealing cover 13 are provided in the cavity 7. A group of lighting lamps 12 for providing light sources are provided on both inner side walls of the inner shell 6, and each group has multiple lighting lamps 12. In the existing device, the air inside is basically in a static state, and the heat at the edge needs to be transferred through air conduction, resulting in a long curing cycle and serious energy waste. Therefore, after starting the electric fan 16 to suck out the air inside the box body 2 and blow it into the first sealing cover 11, the gas is transported to the second sealing cover 13 through the communicating component 8, and then blown into the box body 2 through the air inlet grille 10. By providing the electric fan 16 and the communicating component 8, when the electric fan 16 is started, the air inside the box body 2 is sucked into the communicating component 8 and then blown back into the box body 2, so that the air inside circulates, and thus the heat circulates, thereby shortening the curing cycle and reducing energy waste.

[0025] The baking component 9 in the present invention includes two fixing frames 17 fixedly connected to the inner walls on both sides of the inner shell 6 by bolts. A plurality of sliding plates 18 are slidably connected in the fixing frames 17. One side of each of the plurality of sliding plates 18 is fixedly connected to a heater 19 by bolts. On one outer wall of the outer shell 5, there is a transverse movement component 4 for moving the baking component 9. The transverse movement component 4 includes an electric telescopic rod 25 fixedly connected to one side of the outer shell 5 by bolts. One end of the electric telescopic rod 25 passes through the inner wall on one side of the inner shell 6 and extends into its interior. Two grooves 21 are formed on one side of each of the plurality of sliding plates 18. A connecting frame 22 is fixedly connected to the two grooves 21 on one side of each of the plurality of sliding plates 18 by bolts. One end of the connecting frame 22 is fixedly connected to a U-shaped frame 24 by bolts, and one side of the U-shaped frame 24 is fixed to one end of the electric telescopic rod 25. A plurality of fixing holes 23 with the same interval are formed on the connecting frame 22. When installing the baking component 9, first slide the sliding plates 18 onto the fixing frames 17, then arrange the plurality of sliding plates 18 at the same interval, and then install the plurality of sliding plates 18 onto the connecting frame 22 and fix them. Subsequently, start the electric telescopic rod 25 in the transverse movement component 4 to expand and contract, and then drive the plurality of sliding plates 18 to slide left and right along the fixing frames 17 through the U-shaped frame 24, so that the plurality of heaters 19 move left and right. By providing the baking component 9, the inside of the box body 2 can be continuously heated, and by providing the transverse movement component 4, the plurality of heaters 19 can move left and right in the box body 2, so that multiple parts inside the box body 2 can be heated, increasing the utilization rate of the heaters 19 and further increasing the efficiency of baking paint.

A communicating pipe 29 communicating with both of them is provided between the two connecting pipe racks 28. A control component 30 for controlling the flow direction of the internal gas is provided on the communicating pipe 29. By providing the communication component 8, the first sealing cover 11 and the second sealing cover 13 can be communicated. Through the provided communication component 8, the first sealing cover 11 and the second sealing cover 13 are communicated, so that the air inside the box body 2 circulates, filling the inside of the box body 2 with heat and making the baking paint more sufficient.

[0027] To facilitate the control of the air circulation mode, the control component 30 includes a valve three 35 provided on the connecting pipe 29 for opening and closing. The upper and lower ends of the circumferential outer wall of the connecting pipe 29 are respectively provided with an exhaust pipe 31 and an intake pipe 32 that communicate with its interior. Valves one 33 and valves two 34 for controlling the opening and closing of the exhaust pipe 31 and the intake pipe 32 are respectively provided on the exhaust pipe 31 and the intake pipe 32. When it is necessary to discharge the harmful gas in the device, the control component 30 can be used to close the valve three 35 and open the valve one 33 and the valve two 34. Then, after the air in the box body 2 is sucked out by the electric fan 16, it passes through the pipe rack one 26 and is discharged through the exhaust pipe 31. The joint at the end of the exhaust pipe 31 is connected to the tail gas treatment device, so that the harmful gas can be treated, thereby preventing air pollution. After the gas is extracted, the air pressure in the box body 2 becomes lower, so that the gas in the air is input into the device through the intake pipe 32, forming a new cycle. By means of the control component 30 provided, the opening and closing of the valve one 33, the valve two 34 and the valve three 35 can be controlled according to requirements. When internal circulation is required, the valve one 33 and the valve two 34 are closed and the valve three 35 is opened to make the air circulate inside the box body 2 and recycle the heat. And when external circulation is required, the valve one 33 and the valve two 34 are opened and the valve three 35 is closed, so that the harmful gas in the box body 2 can be discharged, and new air is input into the box body 2 to form a new external circulation to replace the air in the box body 2.

[0028] To facilitate the limitation of the slide plates 18, limiting grooves 20 are opened on the upper and lower surfaces of the plurality of slide plates 18. Limiting strips are fixedly connected between the inner walls on both sides of the fixing frame 17 through bolts, and the limiting strips are embedded in the limiting grooves 20. One side of the box body 2 is fixedly connected with a door frame through bolts. A plurality of door panels are arranged in the door frame, and transparent glass windows are arranged on the plurality of door panels. Two wedge-shaped blocks are fixedly connected to one side of the support plate 1 through bolts. A plurality of avoidance openings 3 for avoiding the control component 30 are opened on both sides of the outer shell 5, and each group has a plurality of them. The control component 30 passes through the avoidance openings 3 and extends out of the device. Through the provided door frame and transparent glass window, it is convenient for the staff to observe the baking situation of the workpieces in the box body 2, which is convenient for real-time observation of its interior. And the slide plates 18 can be guided through the provided limiting strips and limiting grooves 20 to prevent the occurrence of deviation and jamming.

[0029] The present invention is used in the following steps: S1: When it is necessary to install the baking component 9, first slide the slide plates 18 onto the fixing frame 17, then arrange the plurality of slide plates 18 at equal intervals, and then install the plurality of slide plates 18 on the connecting frame 22 and fix them. Then, the electric telescopic rod 25 in the transverse movement component 4 is started to expand and contract, and then the U-shaped frame 24 drives the plurality of slide plates 18 to slide left and right along the fixing frame 17, so that the plurality of heaters 19 move left and right. S2: The air inside the existing device is basically in a static state. The heat at the edge needs to be transferred through air conduction, resulting in a long curing cycle and serious energy waste. Therefore, after starting the electric fan 16 to suck out the air in the box body 2 and blow it into the first sealing cover 11, the gas is transported to the second sealing cover 13 through the connecting component 8, and then blown into the box body 2 through the air inlet grille 10; S3: The connecting component 8 can connect the first sealing cover 11 and the second sealing cover 13. When it is necessary to control the air circulation in the box body 2, the control component 30 can close the valve three 35 and open the valve one 33 and the valve two 34 when it is necessary to discharge the harmful gas in the device. Then, after sucking out the air in the box body 2 through the electric fan 16, it is discharged through the exhaust pipe 31 after passing through the pipe rack one 26. Connect the joint at the end of the exhaust pipe 31 to the tail gas treatment device to treat the harmful gas, thereby preventing air pollution. After the gas is extracted, the air pressure in the box body 2 becomes lower, so the gas in the air is input into the device through the air inlet pipe 32 to form a new cycle.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0031] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
