Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner shell processing, in particular to a spraying device for air conditioner shell processing. Background Art

[0002] During the production process of the air conditioner, the shell needs to be sprayed. The sprayed paint surface adheres to the air conditioner shell, which not only improves the aesthetics of the shell, but also has an anti-rust effect. Currently, when spraying the air conditioner shell, the air conditioner shell is placed on the painting equipment and fixed by a counter-clamping method, so that the paint surface of the air conditioner shell cannot be sprayed completely at one time. The air conditioner shell needs to be clamped again after the paint surface is dry, and the position previously blocked by the clamping needs to be sprayed again, which not only causes color difference of the paint surface, but also increases the spraying process time. Therefore, the inventor proposes an air conditioner shell spraying device to meet the use requirements.

[0003] For example, Chinese patent announcement No. CN220514507U discloses an air conditioner shell spraying device. When in use, the air conditioner shell is installed on a connecting mechanism in a hoisting state. As the hoisting conveyor belt continues to move, the air conditioner shell enters the spray box. At this time, the moving air conditioner shell is sprayed with paint through a nozzle. The paint is led from the storage box to the nozzle through a transmission pipe and a delivery pipe. The nozzles are symmetrically distributed on the inner wall of the spray box. The telescopic cylinder continuously reciprocates and stretches, driving the driving rod to be lifted and lowered by force. The driving rod rotatably connected to the driving rod is forced to rotate with the flip wheel as the The supporting point is flipped, and the connecting frame at the other end of the driving wheel drives the nozzle to swing, so that the sprayed paint is evenly attached to the outer surface of the motor casing. With the continuous movement of the hoisting conveyor platform, the air-conditioning casing is moved to the fan, and the paint on the surface of the air-conditioning casing is dried by wind. Electric heating plates, heating wires and other devices that can provide heat sources can be set at the air outlet of the fan to increase the drying efficiency. When the air-conditioning casing is moved out of the spray box, it is removed by the workers. At this time, the connecting mechanism shrinks and rotates along the hoisting conveyor platform again, and the removed air-conditioning casing can be sent to the next process.

[0004] However, the air conditioner shell spraying device in the above application can only spray the side of the air conditioner at a time, and the top is a dead corner for spraying. Multiple sprayings are required to fully spray its outer surface, and the efficiency is relatively low. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a spraying device for processing an air conditioner shell. Utility Model Content
