[0016] Please see Figure 1-4 The present invention provides the following technical solution: a transmission shaft surface spraying processing device, including a chamber 1, the chamber 1 is installed and fixed on a processing platform 6, a chamber door 4 is hinged to the front end of the chamber 1, an electric push rod 7 is installed at the upper end of the chamber 1, a pressure plate 9 is rotatably connected to the output end of the electric push rod 7, a motor 5 is installed at the lower end of the processing platform 6 corresponding to the pressure plate 9, a turntable 10 is fixed to the output end of the motor 5, a pressure pump 13 is installed at one end inside the chamber 1, a paint inlet pipe 3 is provided at one end of the pressure pump 13, a vertical pipe 11 is fixed at the other end of the pressure pump 13, a plurality of nozzles 12 are fixed at the other end of the vertical pipe 11, a purification component 8 is provided on the upper side of one end of the chamber 1, and a drying component 2 is provided on one side inside the chamber 1; The drying assembly 2 includes a hot air blower 21, a fixed pipe 22, an air outlet 23, an air supply pipe 24, a dust collection box 25, an air inlet 26, a dehumidifying plate 27, and a dust collection plate 28. The hot air blower 21 is installed on one side of the upper end of the processing platform 6. One end of the hot air blower 21 is connected to the dust collection box 25 through a pipe. One end of the dust collection box 25 is provided with an air inlet 26. A dehumidifying plate 27 is installed on one side inside the dust collection box 25. A dust collection plate 28 is provided on one side of the dehumidifying plate 27. A fixed pipe 22 is fixed inside the chamber 1 on the side away from the vertical pipe 11. The fixed pipe 22 is connected to the hot air blower 21 through an air supply pipe 24. One end of the fixed pipe 22 is provided with an air outlet 23.

[0017] Specifically, the drying assembly 2 also includes a fixing hole 29, a sealing plate 210, a fixing bolt 211, and a slot 212. The front end of the dust collector 25 is provided with a sealing plate 210 corresponding to the dehumidifying plate 27 and the dust collector 28. The sealing plate 210 is connected to the dust collector 25 by the fixing bolt 211. The front end of the dust collector 25 is provided with a fixing hole 29 corresponding to the fixing bolt 211. The inside of the dust collector 25 is provided with a slot 212 corresponding to the dehumidifying plate 27 and the dust collector 28.

[0018] By adopting the above technical solution, the sealing plate 210 can be disassembled by unscrewing the fixing bolt 211 from the fixing hole 29. Then, the dust removal plate 28 and the dehumidification plate 27 can be taken out from the slot 212 of the dust removal box 25. The sealing plate 210 and other features facilitate the disassembly and replacement of the dust removal plate 28 and the dehumidification plate 27. At the same time, the installation of the dust removal plate 28 and the dehumidification plate 27 prevents dust and other particles from being blown into the chamber 1.

[0019] Specifically, the drying assembly 2 also includes a rotating rod 213, a baffle 214, and a deflector 215. The rotating rod 213 is rotatably connected to the upper end of the chamber 1 at the position corresponding to the air outlet 23. The baffle 214 is fixed to the lower end of the rotating rod 213, and the deflector 215 is fixed to the upper end of the rotating rod 213.

[0020] By adopting the above technical solution, when spraying the drive shaft, the rotating rod 213 can be rotated in the chamber 1 by the lever 215. The rotation of the rotating rod 213 drives the baffle 214 to rotate to one end of the air outlet 23, which can seal the air outlet 23 and prevent paint from entering the air outlet 23.

[0021] Specifically, the rotating rod 213 is connected to the hopper 1 by a damped rotation, the lower end of the baffle 214 is flush with the lower end of the interior of the hopper 1, and the front end of the dust collector 25 has an installation port corresponding to the sealing plate 210.

[0022] By adopting the above technical solution, the rotating rod 213 is less likely to rotate on its own, the baffle 214 rotates more stably in the chamber 1, and the sealing plate 210 can be installed into the installation port.

[0023] In this embodiment, when using the drive shaft surface spraying device, the device is installed in a suitable position, the drive shaft is placed on the turntable 10, the electric push rod 7 is turned on to push the pressure plate 9 downward to contact the upper end of the drive shaft, thereby clamping and fixing the drive shaft. The chamber door 4 is closed, the paint supply pipe is connected to the paint inlet pipe 3, and the pressure pump 13 delivers the paint to the vertical pipe 11. Several nozzles 12 at one end of the vertical pipe 11 spray the paint onto the surface of the drive shaft. After the drying component 2 is set up, the hot air blower 21 is turned on after the drive shaft surface is sprayed. Air enters the dust collection box 25. The dehumidifying plate 28 and dust collection plate 27 in the dust collection box 25 remove dust and moisture from the air. Then the air enters the hot air blower 21 for heating. The hot air blower 21 sends air to the fixed pipe 22 through the air supply pipe 24. The air outlet 23 at one end of the fixed pipe 22 blows hot air onto the drive shaft, thereby cleaning the surface of the drive shaft. The paint on the surface is dried. The drying component 2 can dry the paint on the surface of the drive shaft after spraying, so as to avoid the slow drying speed of the paint on the drive shaft surface, which would make it difficult to pick up the material and affect the subsequent spraying work of the drive shaft and reduce the working efficiency of the device. The fixing bolt 211 can be unscrewed from the fixing hole 29 to remove the sealing plate 210. Then the dust removal plate 28 and the dehumidification plate 27 can be taken out from the slot 212 of the dust removal box 25. The sealing plate 210 and other features facilitate the disassembly and replacement of the dust removal plate 28 and the dehumidification plate 27. At the same time, the dust removal plate 28 and the dehumidification plate 27 prevent dust from being blown into the chamber 1. When spraying the drive shaft, the lever 213 can be rotated in the chamber 1 by the lever 215. The rotation of the lever 213 drives the baffle 214 to rotate to one end of the air outlet 23, which can seal the air outlet 23 and prevent the paint from entering the air outlet 23. Example

[0024] The difference between this embodiment and embodiment 1 is that the purification component 8 includes an air purifier 81, a fan 82, an intake pipe 83, an air supply pipe 84, and an exhaust pipe 85. The fan 82 is installed on the upper side of one end of the chamber 1, and the intake pipe 83 is installed on the end of the fan 82 near the chamber 1. The air purifier 81 is installed on the upper side of the chamber 1 near the fan 82, and the exhaust pipe 85 is installed on the upper end of the air purifier 81. The air purifier 81 and the fan 82 are connected by the air supply pipe 84.

[0025] By adopting the above technical solution, when drying the paint on the surface of the drive shaft, the suction fan 82 is turned on. The suction fan 82 transports the gas in the chamber 1 to the air purifier 81 through the air supply pipe 84. The air purifier 81 can filter the harmful gases in the chamber 1 and discharge them through the exhaust pipe 85. By setting the purification component 8, the harmful gases in the chamber 1 can be purified before being discharged, reducing the air pollution caused by harmful gases during the spraying process.

[0026] Specifically, the end of the suction pipe 83 away from the suction fan 82 extends into the interior of the chamber 1, and the air supply pipe 84 is connected to the air purifier 81 and the air supply pipe 84 is connected to the suction fan 82 through flanges.

[0027] By adopting the above technical solution, the air intake pipe 83 can draw air from the chamber 1, and the flange connection makes the connection between the air supply pipe 84 and the air purifier 81, as well as between the air supply pipe 84 and the suction fan 82, more secure.

[0028] In this embodiment, by setting the purification component 8, when the paint on the surface of the drive shaft is dried, the suction fan 82 is turned on. The suction fan 82 delivers the gas in the chamber 1 to the air purifier 81 through the air supply pipe 84. The air purifier 81 can filter the harmful gases in the chamber 1 and discharge them through the exhaust pipe 85. By setting the purification component 8, the harmful gases in the chamber 1 can be purified before being discharged, reducing the air pollution caused by harmful gases during the spraying process.

[0030] In this utility model, the electric push rod 7 is a previously disclosed technology, and the selected model is FTG50.

[0031] The suction fan 82 of this utility model is a previously disclosed technology, and the selected model is DJT10-23S.

[0032] The air purifier 81 in this utility model is a previously disclosed technology, and the selected model is KQ-GY-20.

[0033] The structure and working principle of the paint inlet pipe 3, motor 5, processing platform 6, vertical pipe 11, nozzle 12 and pressure pump 13 in this utility model have been disclosed in a transmission shaft spraying mechanism for processing transmission shafts disclosed in Chinese patent application number 2021206925069.

[0034] The working principle and usage process of this utility model: When using the drive shaft surface spraying processing device, install the device in a suitable position, place the drive shaft on the turntable 10, turn on the electric push rod 7 to push the pressure plate 9 downward to contact the upper end of the drive shaft, thereby clamping and fixing the drive shaft. Close the chamber door 4, connect the paint supply pipe to the paint inlet pipe 3, and the pressure pump 13 delivers the paint liquid to the vertical pipe 11. Several nozzles 12 at one end of the vertical pipe 11 spray the paint liquid onto the surface of the drive shaft. After the drive shaft surface is sprayed by the drying component 2, turn on the hot air blower 2. 1. Air enters the dust collection box 25, where dehumidification plates 28 and dust collection plates 27 remove dust and moisture. The air then enters the hot air blower 21 for heating. The hot air blower 21 delivers air to the fixed pipe 22 through the air supply pipe 24. Hot air is blown out of the air outlet 23 at one end of the fixed pipe 22 onto the drive shaft, thus drying the paint on the drive shaft surface. The drying assembly 2 dries the paint on the sprayed drive shaft surface, preventing slow drying that would hinder material handling and affect subsequent drive shaft spraying. The operation of the device is slowed down, reducing its efficiency. The sealing plate 210 can be removed by unscrewing the fixing bolt 211 from the fixing hole 29. Then, the dust removal plate 28 and the dehumidification plate 27 can be removed from the slot 212 of the dust collection box 25. The sealing plate 210 facilitates the disassembly and replacement of the dust removal plate 28 and the dehumidification plate 27. Simultaneously, the installation of the dust removal plate 28 and the dehumidification plate 27 prevents dust from being blown into the chamber 1. During the spraying operation of the drive shaft, the rotating rod 213 can be rotated in the chamber 1 by the lever 215. The rotation of the lever 213 drives the baffle 21. 4. After rotating to one end of the air outlet 23, the air outlet 23 can be sealed to prevent paint from entering the air outlet 23. By setting the purification component 8, when the paint on the surface of the drive shaft is dried, the suction fan 82 is turned on. The suction fan 82 delivers the gas in the chamber 1 to the air purifier 81 through the air supply pipe 84. The air purifier 81 can filter the harmful gases in the chamber 1 and discharge them through the exhaust pipe 85. By setting the purification component 8, the harmful gases in the chamber 1 can be purified before being discharged, reducing the air pollution caused by harmful gases during the spraying process.
