[0027] Preferably: tubular heater 3, axial flow fan 4 and driving motor 6 are electrically connected by control switch and external power supply.

[0028] In specific use, the tubular heater 3, the axial flow fan 4 and the driving motor 6 can be controlled by switches, so that the operator can set the temperature of the tubular heater 3 and the air speed of the axial flow fan 4 through the control switches.

[0029] Preferably, the other end of the exhaust pipe 5 is connected with a communication pipe 15, the other end of the communication pipe 15 extends into a shell 16, the front surface of the shell 16 is provided with a placing groove 17, the filter box 18 is slidably placed in the placing groove 17, and the top surface of the side of the shell 16 away from the exhaust pipe 5 is provided with a ventilation hole 22.

[0030] In specific use, when the gas in the exhaust pipe 5 enters the shell 16 through the communication pipe 15, the flowing air will first pass through the filter box 18 installed in the shell 16 and then be discharged from the ventilation hole 22.

[0031] Preferably, the top surface of the filter box 18 is symmetrically provided with two groups of installation grooves 19, a silk screen filter core 20 is slidably placed in one installation groove 19, and an activated carbon filter core 21 is slidably placed in the other installation groove 19.

[0034] In specific use, when the filter box 18 is slidably placed in the placing groove 17 on the shell 16, the sealing ring 23 on the filter box 18 will move to the sealing groove 24 in the placing groove 17, at this time the sealing ring 23 will be elastically clamped in the sealing groove 24, ensuring the sealing between the filter box 18 and the shell 16, preventing the gas from escaping from the placing groove 17, and the material of the sealing ring 23 is rubber material.

[0035] Preferably, the top surface of the middle position of the shell 16 is through-connected with a butterfly bolt 25, and the other end of the butterfly bolt 25 is threadedly connected with the filter box 18.

[0036] In particular, when the filter box 18 is slid into the placing groove 17 on the shell 16, the butterfly bolt 25 is screwed into the filter box 18 through the shell 16, so that the position of the filter box 18 is fixed in the placing groove 17, and the butterfly bolt 25 is unscrewed, so that the filter box 18 can be pulled out of the placing groove 17 on the shell 16, and the operator can maintain and replace the wire mesh filter element 20 and the activated carbon filter element 21 in the filter box 18.

[0037] It should be noted that the tubular heater 3 is a tubular electric heater, and the axial flow fan 4 is a T35-11 axial flow fan. After the tubular heater 3 is started, the heating pipe will perform heating operation, thereby increasing the temperature inside the box body 1. When the axial flow fan 4 performs air supply operation to the inside of the box body 1, the flow speed of the air inside the box body 1 can be accelerated, and the flowing air is discharged from the exhaust pipe 5, so that the air inside the box body 1 is in a circulating flow state. The box door 2 is provided with a transparent observation window, which facilitates the operator to observe the situation inside the box body 1 through the box door 2. The box door 2 is fixed to the box body 1 by a door lock.

[0038] Working principle: when using the device for baking motor rotor, the motor rotor 14 after dipping paint is placed between the two roller shafts 11 by opening the box door 2, and the motor rotor 14 is placed in contact with the two roller shafts 11 at the bottom. After the motor rotor 14 is placed, the box door 2 is closed, the tubular heater 3 and the axial flow fan 4 are started, the heating pipe on the tubular heater 3 starts heating operation, thereby increasing the temperature inside the box 1. At this time, the axial flow fan 4 also blows air into the box 1, which accelerates the flow speed of the air in the box 1, and the flowing air is discharged from the exhaust pipe 5, so that the air in the box 1 is in a circulating flow state. The driving motor 6 is started, and the output end of the driving motor 6 drives the rotating shaft 7 to rotate in the bearing 8. At this time, the rotating shaft 7 drives the large chain wheel 9 to rotate, and the large chain wheel 9 drives the small chain wheel 12 to rotate through the meshing chain 13. At this time, the roller shaft 11 connected to the small chain wheel 12 rotates on the support frame 10, and the roller shaft 11 rotates with the placed motor rotor 14, so that the rotating motor rotor 14 can be evenly heated and dried in the box 1, ensuring that the insulating paint is evenly dried and attached to the motor rotor 14, preventing the motor rotor 14 from being static during drying, which affects the uniformity of the distribution of the insulating paint. Secondly, when the motor rotor 14 is dried in the box 1, harmful gases are generated during the drying of the insulating paint. The harmful gases generated are discharged from the exhaust pipe 5, and then enter the shell 16 through the communication pipe 15. When the harmful gases flow in the shell 16, the wire mesh filter element 20 and the activated carbon filter element 21 in the filter box 18 in the shell 16 can filter the particulate matter and harmful substances in the flowing air, so that the filtered air is discharged to the outside environment through the air vent 22, preventing the harmful gases generated during drying from being directly discharged into the air to pollute the working environment.

[0039] Finally, it should be pointed out that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, and for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced.
