[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. During valve manufacturing, their surfaces need to be coated. Coating not only provides a protective coating for the valve, enhancing its corrosion resistance and wear resistance, and extending its service life, but also improves the valve's appearance quality, meeting the different customer requirements for product appearance.

[0003] Traditional spraying equipment can only spray one valve at a time, and the valve is usually stationary during the spraying process, which results in blind spots after one spraying and requires touch-up spraying, affecting processing efficiency. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] Please see Figure 1-6In this embodiment of the present invention, a valve spraying device includes a spraying box 100, a rotating disk 200, a planetary gear 300, a connecting rod 400, a drive motor 500, and a hollow box 600. A partition plate 110 is fixedly connected inside the spraying box 100. A circular mounting groove 111 is formed through the top surface of the partition plate 110. A door opening is formed on the front side wall of the spraying box 100, and a door 120 is rotatably connected to the door opening via a hinge. The rotating disk 200 is installed in the circular mounting groove 111. The turntable 200 and the circular mounting groove 111 are rotatably connected by a high-precision bearing, and a sealing structure is provided at the connection between the turntable 200 and the circular mounting groove 111 to prevent leakage of the spraying material. The planetary gear 300 is mounted on the bottom surface of the turntable 200. The planetary gear 300 includes a sun gear 310, an internal gear ring 320, a planet carrier 330, and several planet gears 340. The internal gear ring 320 and the planet carrier 330 are fixedly connected to the bottom surface of the turntable 200. The sun gear 310, The internal gear ring 320 and planetary gears 340 are both made of high-quality alloy steel and undergo heat treatment to improve their strength and wear resistance. Several insertion rods 400 are arranged at equal angles on the top surface of the rotating disk 200, and are rotatably connected to the top surface of the rotating disk 200. The bottom ends of the insertion rods 400 are connected to several planetary gears 340. Two support rods 420 are symmetrically rotatably connected to the outer walls of the insertion rods 400. The valve is fixed by a V-shaped support. The drive motor 500 is installed on the bottom of the spray box 100. The motor shaft of the drive motor 500 is connected to the rotating shaft 510 through a coupling. The top end of the rotating shaft 510 passes through the interior of the spray box 100 and is fixedly connected to the sun gear 310. The hollow box 600 is installed on the inner side wall of the spray box 100. Several nozzles 610 are installed at equal intervals on the side wall of the hollow box 600 facing the plug rod 400. The other side wall of the hollow box 600 is connected to the feed pipe 620.

[0032] Specifically, before the valve spraying operation, the operator first places the valves to be sprayed one by one onto the plug rod 400 on the top surface of the rotating disk 200. The two support rods 420 on the plug rod 400 extend outwards and are adaptively adjusted according to the inner wall size of the valve. After the valve installation is completed, the drive motor 500 on the bottom surface of the spraying box 100 is started. The drive motor 500 is powered on and runs, transmitting power to the rotating shaft 510 through the coupling, causing the rotating shaft 510 to start rotating. Since the outer wall of the rotating shaft 510 is fitted with the sun gear 310 of the planetary gear 300, the rotation of the rotating shaft 510 will drive the sun gear 310 to rotate synchronously. The sun gear 310 serves as the power input end of the planetary gear 300 transmission system, and its rotation will drive the planet gear 340 meshing with it. The bottom surface of the rotating disk 200 is fixedly connected to the internal gear ring 320 and the planet carrier 330. Driven by the sun gear 310, the planet gear 340 revolves around the sun gear 310 on one hand and is driven by the sun gear 310 on the other hand. Since the planetary gear 340 meshes with the internal gear ring 320, the planetary gear 340 also rotates along the inner wall of the internal gear ring 320. Therefore, the revolution and rotation of the planetary gear 340 will drive the insertion rod 400 to revolve and rotate synchronously. That is to say, the valve placed on the insertion rod 400 will revolve around the center of the rotating disk 200 and rotate around its own axis together with the insertion rod 400. While the valve is revolving and rotating, the valve is positioned in the spray box 10. Several nozzles 610 on the inner wall of the hollow box 600 start working. The hollow box 600 is connected to the external spraying material supply system through the feed pipe 620. The spraying material (such as paint, coating, etc.) is sprayed out from the nozzles 610 under a certain pressure to form a mist of spraying particles. As the valve is constantly revolving and rotating, the spraying particles sprayed out by the nozzles 610 can evenly cover the various surfaces of the valve from different angles and directions, effectively eliminating spraying dead corners and achieving a uniform spraying effect.

[0033] like Figure 5-6 As shown, in this embodiment, two concave platforms 410 are symmetrically formed on the outer wall of the plug rod 400. A rotating seat 411 is fixedly connected to the side wall of each of the two concave platforms 410. Two support rods 420 are respectively set at the two concave platforms 410. The top ends of the two support rods 420 are rotatably connected to the inner top surface of the two concave platforms 410. A rotating seat 421 is fixedly connected to the side wall of the two support rods 420 that are close to each other. A rotating rod 430 is rotatably connected inside each of the two rotating seats 421. The other ends of the two rotating rods 430 are rotatably connected to the two rotating seats 411. A torsion spring is installed between the rotating seats 411 and the rotating rods 430. A tray 440 is sleeved and fixed to the outer wall of the plug rod 400. A round rod 422 is fixedly connected through the bottom end of each of the two support rods 420. A connecting plate 451 is fixedly connected to both ends of the round rod 422. A rubber block 450 is fixedly connected between the two connecting plates 451.

[0034] In this embodiment, since a torsion spring is provided at the connection between the rotating seat 411 and the rotating rod 430, the two rotating rods 430 unfold relative to each other under the action of the torsion spring, thereby supporting the two support rods 420 respectively, so that the two support rods 420 unfold in a V-shape. When the valve is fitted onto the plug rod 400 from top to bottom, the two rubber blocks 450 can be pinched first to close the two support rods 420. After the bottom end of the valve contacts the top surface of the tray 440, the two rotating rods 430 will automatically open the support rods 420 under the action of the torsion spring, so that the two support rods 420 unfold and the two rubber blocks 450 are tightly attached to the inner wall of the valve, so that the valve is fixed on the plug rod 400.

[0035] like Figure 5 As shown, in this embodiment, two symmetrically spaced slots 441 are formed on the top surface of the tray 440. L-shaped rods 460 are rotatably connected to the bottom ends of both support rods 420, and the two L-shaped rods 460 are slidably inserted into the two slots 441 respectively.

[0036] In practice, when the spraying is finished and the valve needs to be removed, the bottom of the two L-shaped rods 460 can be pressed down so that the two L-shaped rods 460 move closer to each other along the strip groove 441, thereby driving the two support rods 420 to move closer to each other, applying pressure to the rotating rod 430, so that the two support rods 420 gradually close together, at which point the valve can be removed from the plug rod 400.

[0037] like Figure 1-2 As shown, in this embodiment, the top surface of the spray box 100 is provided with an exhaust port 130, the top surface of the exhaust port 130 is connected to an exhaust pipe 700, a fan blade 710 is installed inside the exhaust port 130, and an observation window 121 is provided on the surface of the box door 120.

[0038] In practice, the exhaust gas generated during re-spraying inside the spray box 100 can be discharged to the exhaust gas treatment device through the exhaust pipe 700 by activating the fan blades 710, thereby reducing pollution to the external environment. After the box door 120 is closed, the spraying status of the internal valves can be observed through the observation window 121.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
