The nozzle 805 is provided to atomize the paint and spray it onto the surface of the ball valve, thereby enabling the paint to evenly adhere to the ball valve, thereby improving the quality and aesthetics of the painting.

[0031] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 As shown, the pre-drying mechanism 9 includes a resistance wire heater 901, a limiting hole 902, a blowing fan 903, a heat insulation cover 904 and an exhaust hole 905, and the resistance wire heater 901 is fixedly connected to both sides of the top of the support frame 3.

[0032] Specifically, such as Figure 3 As shown, the limiting holes 902 are opened on both sides of the rear side of the workbench 1 , and the blowing fan 903 is fixedly connected to the inner side of the limiting hole 902 .

[0033] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 As shown, the heat shield 904 is fixedly connected to the surface of the limiting hole 902 , and the exhaust hole 905 is opened on the rear side of the top of the workbench 1 .

[0034] In this embodiment: a resistance wire heater 901 is provided to generate heat to pre-dry the paint on the surface of the ball valve; a limiting hole 902 is provided to provide an installation position for a blowing fan 903, and at the same time, the position and angle of the blowing fan 903 are limited to ensure that the blowing fan 903 can blow the heat generated by the resistance wire heater 901 evenly toward the surface of the ball valve; the heat generated by the resistance wire heater 901 is blown toward the surface of the ball valve by the blowing fan 903 to accelerate the drying process of the paint; a heat insulation cover 904 is provided to prevent the heat generated by the resistance wire heater 901 from being lost through the limiting hole 902, thereby improving the efficiency of pre-drying; and an exhaust hole 905 is provided to discharge the waste gas and moisture generated during the pre-drying process to keep the working environment clean and dry.

[0035] Specifically, such as Figure 4 As shown, a dust filter 10 is fixedly connected to the top of the inner side of the exhaust hole 905, and the surface of the dust filter 10 is coated with anti-corrosion paint.

[0036] Specifically, such as Figure 1 、 Figure 5 As shown, the conveyor belt 4 is configured as a filter mesh, and the surface of the conveyor belt 4 is coated with anti-corrosion paint.

[0037] In this embodiment: by setting a dust-proof filter 10, it is possible to effectively prevent external dust and other impurities from entering the interior of the paint spraying device through the exhaust hole 905. During the painting and pre-drying process, the cleanliness of the air inside the device is maintained to prevent dust from contaminating the paint layer on the surface of the ball valve, thereby ensuring the quality of the paint spraying. By setting an anti-corrosion coating, the durability of the dust-proof filter 10 is enhanced to prevent it from being corroded and damaged due to long-term contact with humid air and paint mist, thereby extending its service life. By setting the conveyor belt 4 to a filter shape, the filter mesh design is beneficial in that during the painting process, excess paint can fall through the filter and return to the receiving tray 13 for recycling, thereby improving the utilization rate of the paint and reducing production costs. By setting an anti-corrosion coating, the conveyor belt 4 can be protected from corrosion by paint and other chemicals, ensuring that the conveyor belt 4 maintains good performance and stability during long-term use, thereby extending the service life of the conveyor belt 4.

[0038] Specifically, such as Figure 5 As shown, a base 11 is fixedly connected to the surface of the pressure pump 802 , and a side of the base 11 away from the pressure pump 802 is bolted to the left side of the workbench 1 .

[0039] Specifically, such as Figure 4 As shown, a discharge port 12 is provided on the right side of the workbench 1 , and a receiving tray 13 is slidably connected to the inner side of the discharge port 12 .

[0040] In this embodiment: by setting up the base 11, a stable installation foundation is provided for the pressure pump 802, reducing the vibration and displacement of the pressure pump 802 during operation, ensuring that the pressure pump 802 can work stably, thereby ensuring the pressurization effect of the paint and the uniformity of the paint spraying. By setting up the discharge port 12, it is convenient for the user to slide in or pull out the receiving tray 13 to centrally process the recycled paint. By setting up the receiving tray 13, the excess paint in the painting process can be collected and limited.

[0041] Working principle: First, the user places the paint spraying device for ball valve processing in a suitable working position. Then, when the ball valve needs to be sprayed, the user adds paint to the storage bin 6 through the feeding port 7. After that, the user turns on the power and starts the motor 5. The output end of the motor 5 drives the conveyor belt 4 to rotate inside the support frame 3, and the conveyor belt 4 drives the ball valve to move. When the ball valve moves to the bottom of the spraying mechanism 8, the user turns on the power and starts the pressure pump 802. The pressure pump 802 extracts paint from the storage bin 6 through the extraction pipe 801 and pressurizes it. The pressurized paint is transported to the diversion pipe 804 through the delivery pipe 803. The diversion pipe 804 The paint is evenly distributed to each nozzle 805, and the nozzle 805 atomizes the paint and sprays it onto the surface of the ball valve. During the painting process, excess paint can fall through the conveyor belt 4, and the receiving tray 13 collects the excess paint. Then, during the painting process, the pre-drying mechanisms 9 on both sides of the top of the support frame 3 are started at the same time, the resistance wire heater 901 generates heat, and the blowing fan 903 blows the heat generated by the resistance wire heater 901 evenly onto the surface of the ball valve to accelerate the drying process of the paint. Finally, when the ball valve completes the painting and pre-drying operations, it is sent out through the back side of the workbench 1, and the user can send the painted ball valve to the next process.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
