[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a motor to rotate a motor-driven rotating rod. The motor-driven rod rotates a belt, which in turn rotates a rotating rod, which in turn rotates a fixed block. The fixed block then rotates a second rotating rod, which in turn rotates a connecting rod. This connecting rod pulls a third rotating rod downwards, causing the piston to slide up and down along the inner wall of the piston tube. As the piston tube slides downwards, negative pressure forces the exhaust piston downwards along the exhaust port, blocking it and preventing external airflow from entering. Simultaneously, internal negative pressure forces the intake piston downwards along the intake port, drawing air from the intake pipe into the piston tube. The intake pipe also draws air from the distribution pipe. When the piston moves upwards, the internal pressure forces the intake piston upwards along the intake port, blocking it. Simultaneously, the internal pressure pushes the exhaust piston upwards along the exhaust port, expelling it outwards. The air is then filtered through an air filter before being released. This design effectively draws in and removes fine dust and debris from the product surface, improving the subsequent coating application effect.

[0019] This invention allows for easy filter replacement by pulling a limiting slider downwards along the second slide groove when the filter needs to be replaced. The limiting slider compresses the spring downwards, causing the surface of the limiting slider to disengage from the spring. Then, the connecting pipe is rotated upwards around the fourth rotating rod, causing the connecting pipe to disengage the limiting buckle from the second slide groove. The filter base is then rotated along the limiting slide groove, allowing it to be removed outwards. The filter base moves the filter, facilitating filter replacement and preventing blockage of the air intake pipe due to prolonged filter neglect, which would affect the air intake performance.

[0020] This invention involves operating a spraying machine when the dust-removed product moves directly under the nozzle. The spraying machine transports the paint from inside the tank to the outlet pipe, then along the outlet pipe into the distribution pipe, and finally sprays it onto the product surface through the nozzle.

[0021] This invention utilizes a second motor, whose output end rotates a second motor rotating rod, which in turn rotates a conveyor belt rotating rod. This rotating rod then rotates the conveyor belt, causing the products on the conveyor belt surface to move. This design offers excellent durability and is suitable for long-term operation.
