The other side of the support frame 1 is provided with a control panel 27. During operation, in practical applications, dust on the surface of the steel structure is usually removed by a brush. However, it is difficult to effectively clean the impurities and debris on its surface, which affects the adhesion quality of the subsequent coating, resulting in problems such as weak coating bonding and easy peeling. When pre-treatment work is required, the driving motor 11 is started through the control panel 27, driving the connecting rod 12 to rotate, and then pushing the slider 10 to slide inside the hollow groove 9, so that the connecting rod 8 drives the piston plate 7 to reciprocate inside the piston cylinder 5. When the piston plate 7 moves away from the delivery pipe 2, water is sucked into the piston cylinder 5 from the water inlet pipe 6. When the piston plate 7 moves towards the delivery pipe 2, the water inside the piston cylinder 5 is pressed into the delivery pipe 2 through the straight pipe, then enters the connecting pipes 3 at both ends respectively, and is evenly sprayed out from the nozzles 4 to spray water on both sides of the cleaned metal part, which can comprehensively perform cleaning and water spraying pre-treatment on the workpiece, ensure the adhesion quality of the subsequent coating, and improve the processing effect on the tool.

On the one hand, it pushes the metal parts to move, and on the other hand, when the metal parts pass through the cleaning rollers 21, the cleaning rollers 21 clean the surface of the workpiece to remove some stubborn impurities, improving the pretreatment effect on the metal parts.

[0025] Working principle: The rotating roller 14 and the support roller 15 together form a horizontal conveying surface. The metal parts slide on this conveying surface. The conveying motor 16 drives the rotating roller 14 to rotate through the rotating shaft 13, thereby driving the metal parts to move forward on the support roller 15.

When the piston plate 7 moves away from the conveying pipe 2, water will be sucked into the piston cylinder 5 from the water inlet pipe 6. When the piston plate 7 moves towards the conveying pipe 2, the water in the piston cylinder 5 will be pressed into the conveying pipe 2 through the straight pipe, then enter the connecting pipes 3 at both ends respectively, and be evenly sprayed out from the nozzles 4 to spray water on both sides of the cleaned metal part, enabling comprehensive cleaning and water spraying pretreatment of the workpiece, ensuring the adhesion quality of the subsequent coating, and improving the processing effect on the tool.
