Description

Technical Field

[0001] This application relates to the field of spraying equipment technology, and specifically to a surface spraying machine for a flue gas check valve. Background Technology

[0002] In modern high-rise buildings, residents' exhaust systems typically discharge through a shared flue. To prevent cooking fumes from flowing back into other residents' homes through this flue, a check valve is usually installed at the exhaust port of the range hood or integrated cooktop to prevent backflow of fumes. However, to ensure the long-term stable operation of the check valve, its surface usually requires a coating treatment to improve its oxidation and corrosion resistance, adapting to various complex operating environments.

[0003] Currently, the surface coating equipment for check valves primarily involves clamping and fixing the check valve before spraying. While this method accomplishes the coating task to some extent, the clamping device obstructs parts of the check valve's surface, preventing these areas from being evenly coated. This negatively impacts the overall coating quality and corrosion resistance of the check valve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a surface spraying machine for flue gas check valves to solve the problems mentioned in the background art.

[0005] According to one aspect of this application, a surface spraying machine for a flue gas check valve includes a base, a support frame, a telescopic electric cylinder, a lifting seat, a rotating mechanism, a spraying assembly, and a pneumatic chuck. The support frame is fixedly mounted on the base. A telescopic electric cylinder is vertically fixedly mounted on the top of the support frame. The extended end of the telescopic electric cylinder extends downward through the top of the support frame and is fixedly connected to the top of the lifting seat. A rotating mechanism is mounted on the bottom of the lifting seat. A spraying assembly is fixedly mounted on the rotating mechanism. A pneumatic chuck is fixedly mounted on the base directly below the spraying assembly via a fixed seat. The pneumatic chuck is used to clamp and fix the inner wall of the check valve body. In use, the telescopic electric cylinder drives the lifting seat to descend, causing the spraying assembly to descend to the outer periphery of the check valve body. The rotating mechanism drives the spraying assembly to rotate and spray around the outer surface of the check valve body.

[0006] Preferably, the rotating mechanism includes a slewing bearing, a rotating shaft, an external gear disk, a drive gear, a rotary motor, and a U-shaped mounting base. The slewing bearing is fixedly installed at the center of the bottom of the lifting seat. The rotating shaft is rotatably installed on the slewing bearing. The lower end of the rotating shaft is fixedly connected to the upper end of the external gear disk. The external gear disk is meshed with the drive gear for transmission. The drive gear is fixedly connected to the output shaft of the rotary motor. The rotary motor is fixedly installed at the bottom of the lifting seat. The lower end of the external gear disk is fixedly connected to the outer horizontal surface of the U-shaped mounting base. The spraying assembly is fixedly installed on the inner side of the U-shaped mounting base.

[0007] Preferably, the spraying assembly includes an input hose, a U-shaped feed pipe, and diffusion nozzles. The inner side of the U-shaped mounting base is fixedly connected to the U-shaped feed pipe. The shape of the U-shaped feed pipe is adapted to the shape of the U-shaped mounting base. Multiple diffusion nozzles are evenly and equidistantly arranged on the U-shaped feed pipe. The diffusion nozzles located in the vertical direction of the U-shaped feed pipe are arranged horizontally inward, and the diffusion nozzles located in the horizontal direction of the U-shaped feed pipe are arranged vertically downward. The U-shaped feed pipe is also connected to the input hose, and the input hose is externally connected to the spraying paint tank.

[0008] Preferably, the vertical length of the U-shaped conveying pipe is greater than the height of the check valve body, and the horizontal length of the U-shaped conveying pipe is greater than the diameter of the check valve body.

[0009] Preferably, the pneumatic chuck is provided with at least two claws that slide outwards and are secured to the inner wall of the check valve body during use.

[0010] The advantages of this application compared to the prior art are as follows: The flue gas check valve surface spraying machine of this application, through the arrangement of a telescopic electric cylinder, a rotating mechanism, a spraying assembly, and a pneumatic chuck, allows the check valve body to be placed on the pneumatic chuck during spraying. Then, the jaws on the pneumatic chuck slide outwards to secure the inner wall of the check valve body, thus fixing it in place. This does not affect the spraying assembly's spraying operation on the outer surface of the check valve body. Then, the extended end of the telescopic cylinder drives the lifting seat to descend, which in turn drives the rotating mechanism and the spraying assembly to descend, allowing the spraying assembly to lower... The device descends to the outer periphery of the check valve body, then starts the rotating motor of the rotating mechanism, which drives the drive gear to rotate, which in turn drives the outer gear disc to rotate. Through the U-shaped mounting base, the U-shaped feed pipe of the spraying assembly rotates around the outer side of the check valve body for spraying. This allows the vertical and horizontal diffusion nozzles of the U-shaped feed pipe to spray the outer and top surfaces of the check valve body, respectively. The clamping structure of this device does not obstruct any part of the check valve's surface, thus ensuring uniform spraying of the check valve surface and guaranteeing the spraying quality of the check valve.

A U-shaped mounting base 56 is provided. A slewing bearing 51 is fixedly mounted at the center of the bottom of the lifting base 4. A rotating shaft 52 is rotatably mounted on the slewing bearing 51. The lower end of the rotating shaft 52 is fixedly connected to the upper end of the external gear disk 53. The external gear disk 53 is meshed with a drive gear 54. The drive gear 54 is fixedly connected to the output shaft of a rotary motor 55. The rotary motor 55 is fixedly mounted at the bottom of the lifting base 4. The lower end of the external gear disk 53 is fixedly connected to the outer horizontal surface of the U-shaped mounting base 56. A spraying assembly 6 is fixedly mounted on the inner side of the U-shaped mounting base 56. The spraying assembly 6 includes... The assembly includes an input hose 61, a U-shaped conveying pipe 62, and diffusion nozzles 63. The inner side of the U-shaped mounting base 56 is fixedly connected to the U-shaped conveying pipe 62. The shape of the U-shaped conveying pipe 62 is adapted to the shape of the U-shaped mounting base 56. Multiple diffusion nozzles 63 are evenly and equidistantly arranged on the U-shaped conveying pipe 62. The diffusion nozzles 63 located vertically on the U-shaped conveying pipe 62 are positioned horizontally inwards, while the diffusion nozzles 63 located horizontally on the U-shaped conveying pipe 62 are positioned vertically downwards. The U-shaped conveying pipe 62 is also connected to the input hose 61. 1.

At least two claws 9 are slidably provided on the pneumatic chuck 7. When in use, the claws 9 slide outward and lock into the inner wall of the check valve body 8.

[0017] Working principle: During spraying, the check valve body 8 is placed on the pneumatic chuck 7, and then the jaws 9 on the pneumatic chuck 7 slide outward to lock the inner wall of the check valve body 8, thus fixing it in place without affecting the spraying operation of the spraying assembly 6 on the outer side of the check valve body 8.

Then, the rotation motor 5 of the rotating mechanism 5 is started. 5. This drives the drive gear 54 to rotate, which in turn drives the external gear disc 53 to rotate. Through the U-shaped mounting base 56, the U-shaped feed pipe 62 of the spraying assembly 6 rotates around the outer side of the check valve body 8 for spraying. This allows the vertical and horizontal diffusion nozzles 63 of the U-shaped feed pipe 62 to spray the outer side and top surface of the check valve body 8, respectively. The clamping structure of this device does not obstruct part of the check valve surface, thus ensuring uniform spraying of the check valve surface and guaranteeing the spraying quality of the check valve.
