Description

Technical Field

[0001] This utility model relates to the field of faucet surface treatment, and in particular to a spraying device for faucet processing. Background Technology

[0002] Faucet spraying is a key step in the manufacturing process, which can give faucets an attractive appearance, enhance corrosion resistance, and improve the overall quality of the product.

[0003] Currently, most spraying devices use fixed nozzles with a single-axis rotating station, resulting in a single spraying trajectory (such as a straight line or a circle). This leads to uneven coating coverage (thickness deviation ≥15%) on curved areas of the faucet (such as the inside of the handle and the recessed area of ​​the spout), which easily causes defects such as missed spraying or paint accumulation. Furthermore, due to the limitation of the single-motor drive structure, it is impossible to achieve synchronous rotational spraying at multiple stations, and only 1-2 faucets can be processed at a time, resulting in reduced spraying efficiency.

[0004] Therefore, there is an urgent need to develop a spraying device for faucet processing. Utility Model Content

Three rotating rods 12 are rotatably installed on the upper part of the bearing plate 11. A placement platform 121 is installed on the upper part of the rotating rods 12 by bolts. The rotating rods 12 drive the placement platform 121 to rotate, forming a spiral spraying trajectory. Four symmetrical plugs 15 are slidably installed on the upper part of the placement platform 121. The upper part of the placement platform 121 is provided with a sliding groove for the plugs 15. The upper part of the plugs 15 is rounded and protruding to assist in contacting the faucet through hole.

[0026] like Figure 3 and Figure 4 As shown, it also includes a pump body 9 and an input pipe valve 10. The pump body 9 is installed in series with the connection between the delivery pipe 81 and the telescopic hose 8 via a flange, and the pump body 9 is connected to the control system via a cable. The pump body 9 is used to provide power for coating delivery and to regulate flow and pressure. An input pipe valve 10 is installed on one side of the lower part of the solution chamber of the machine body 1 via a flange to control the flow rate of external coating entering the solution chamber. The input pipe valve 10 is connected to the external supply pipe.

[0027] like Figure 5As shown, the auxiliary part includes gear 13, gear 2131 and motor 14. Gear 13 is installed at the lower part of the central rotating rod 12 via a keyway, and gear 2131 is installed at the lower part of the rotating rods 12 on both sides via keyways. Gear 2131 meshes with gear 13 in the middle. Motor 14 is installed on the lower front side of the machine body 1 via bolts. The output shaft of motor 14 is connected to gear 13 above via a coupling. Motor 14 provides rotational power to drive gear 13 and rotating rod 12 system. Gear 13 acts as the driving gear, transmitting power from motor 14 to gear 211 on both sides. Gear 2131 acts as the driven gear, driving rotating rods 12 on both sides to rotate synchronously.

[0028] like Figure 1 and Figure 7 As shown, it also includes a mounting frame 17, a fan 18, a heating wire module 19, and a centralized air outlet duct 20. The mounting frame 17 is bolted to one side of the upper part of the body 1. The fan 18 is installed in the upper part of the mounting frame 17, with the air supply end of the fan 18 facing the inside of the body 1. The heating wire module 19 is installed in the lower part of the mounting frame 17 to heat the air to the set temperature and accelerate the curing of the coating. The centralized air outlet duct 20 is connected to the lower part of the upper part of the body 1, corresponding to the air supply end of the fan 18, through a flange. The centralized air outlet duct 20 is connected to the air supply end of the fan 18 and evenly distributes hot air to the surface of the faucet.

[0030] Before spraying, the operator opens the observation window 2, places the faucet to be sprayed on the placement platform 121, uses the rounded protruding structure of the plug 15 (adapted to the faucet's through hole) for positioning, and uses the spring 16 for flexible clamping to avoid scratching the surface. The motor 14 is started, and through the meshing of gear one 13 and gear two 131 on both sides, the three rotating rods 12 are driven to rotate synchronously. The input valve 10 is opened, and the external paint is input into the solution chamber through the pipeline. The pump body 9 is started, and the paint is transported to the telescopic hose 8 through the delivery pipe 81, finally entering the storage cylinder 6. The electric slide rail 4 is started, driving the slide 5 to move vertically, which in turn moves the nozzle 7 to adjust the spraying height. The paint in the storage cylinder 6 is atomized and sprayed out through the nozzle 7. The spraying thickness is controlled by the linkage between the pump body 9 pressure and the slide 5 movement speed. The platform 121 rotates synchronously under the transmission of gear 13 and gear 2 131, forming a spiral spraying trajectory on the faucet surface, enabling parallel spraying of multiple faucets. The telescopic hose 8 automatically extends and retracts with the movement of the slide 5, avoiding pipe tangling and ensuring a continuous supply of paint. After spraying, the fan 18 starts, drawing in external air and heating it to the set temperature through the heating wire module 19. The air is then blown evenly onto the faucet surface through the centralized air outlet duct 20, accelerating the curing of the coating. The purifier 21 operates synchronously, drawing sprayed volatiles into the air supply duct, filtering them through the adsorption plate 22, and then discharging them. After spraying, the slide 5 returns to its initial position, the pump 9 stops supplying material, the heating wire module 19 cools down, the platform 121 stops rotating, the operator opens the observation window 2 to remove the faucet, and the plug 15 automatically resets under the action of the spring 16.
