Description

Technical Field

[0001] This utility model relates to the field of gate valve manufacturing technology, specifically a high-efficiency painting device for gate valve manufacturing and processing. Background Technology

[0002] A gate valve, also known as a stop valve, is a type of forced-seal valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to ensure a leak-proof seal. Gate valves require multiple processing steps during manufacturing, with painting being a particularly important one.

[0003] Most existing spray painting equipment for gate valve production and processing requires manual spraying and manual rotation of the gate valve, which not only results in low spraying efficiency but also endangers the health of operators. Utility Model Content

A connecting rod is flexibly connected to the outer side of the conveying chain, and a fixed plate is fixedly installed at the bottom end of the connecting rod. A rotating rod is rotatably installed on the upper surface of the fixed plate. A hook is fixedly installed at the bottom end of the rotating rod. The gate valve can be easily hung by the hook. The conveying wheel drives the conveying chain to rotate, and the conveying chain drives the fixed plate to move through the connecting rod. The fixed plate is kept stable by the movement of an arc-shaped slider in an annular groove. The fixed plate drives the rotating... The rotating rod moves, causing the shut-off valve to enter the spray chamber from the inlet / outlet. The rotation of the rotating rod, in turn, rotates the shut-off valve, thus improving spraying efficiency. A rack is installed inside the spray chamber, and a gear is fixedly fitted onto the outside of the rotating rod. The gear works in conjunction with the rack, allowing movement and rotation along the rack. Symmetrically distributed annular grooves are formed on the inner wall of the annular groove, and an arc-shaped slider is installed inside each groove. The opposite side of the arc-shaped slider is fixedly connected to the outside of the fixed plate. The movement of the arc-shaped slider within the annular grooves ensures stable movement of the fixed plate. A motor is fixedly installed at one end of the conveyor plate, and the end of the motor's output shaft is fixedly connected to one end of the rotating shaft, providing power for the shaft's rotation. Symmetrically distributed cross grooves are formed through the outside of the spray chamber, and the rack is fixedly installed inside these grooves. The cross grooves connect to the inlet / outlet and facilitate rack installation and allow the rotating rod to easily enter and exit the spray chamber. An observation window is provided on the outside of the spray chamber, allowing observation of the spraying process.

[0006] Preferably, the painting assembly includes a support plate, which is symmetrically distributed and fixedly installed in the painting chamber.

The fixed rod 44 moves through the spray nozzle 46 of the mounting plate 45, thus adjusting the height of the spray nozzle 46. Then, hang the handwheel of the shut-off valve on the hook 29 near the spray chamber 3 and start the motor 215. The end of the output shaft of the motor 215 drives the rotating shaft 23 to rotate. The rotating shaft 23 drives the conveyor wheel 24 to rotate. The conveyor wheel 24 drives the conveyor chain 25 to rotate. The conveyor chain 25 moves through the connecting rod 26 to move the fixed plate 27. The arc-shaped slider 213 moves within the annular slide groove 212 to maintain its position. The fixed plate 27 is stable, and the fixed plate 27 drives the rotating rod 28 to move, so that the rotating rod 28 drives the shut-off valve to enter the paint spraying chamber 3 from the inlet and outlet 5. At the same time, the rotating rod 28 drives the gear 211 to mesh with the rack 210, so that the gear 211 moves and rotates on the rack 210. The gear 211 drives the rotating rod 28 to rotate, which in turn drives the shut-off valve to rotate. This can rotate the shut-off valve to improve the painting efficiency. At the same time, the external supply equipment is started to send paint into the paint nozzle 46 through the connecting pipe and spray it out from the paint nozzle 46. The shut-off valve rotates to cooperate in the painting. The rotating rod 28 drives the shut-off valve to move into the drying chamber 7 for drying. After drying, the shut-off valve is moved out of the drying chamber 7 from the inlet and outlet 5. At the same time, the handwheel of the shut-off valve can be removed from the hook 29.
