Description

Technical Field

[0001] This utility model relates to the field of metal surface rust removal technology, and in particular to a workpiece surface anti-rust spraying equipment. Background Technology

[0002] A workpiece surface anti-rust spraying equipment is a professionally designed device to improve the corrosion resistance and extend the service life of workpieces. It aims to form a dense anti-rust coating on the workpiece surface through an efficient and uniform spraying process. It is widely applicable to many fields such as machinery manufacturing, automotive industry, and metal processing. Through the synergistic cooperation of these components, this anti-rust spraying equipment not only significantly improves the efficiency and quality of workpiece anti-rust treatment, but also reduces labor costs and resource consumption, which is of great significance to promoting the green and efficient development of the manufacturing industry.

[0003] Integrating intelligent spraying, precise flow control, and uniform coverage technologies, this equipment provides a professional solution for workpiece rust prevention. Features include intelligent spraying, precise flow control, electrostatic adsorption spraying, environmental adaptive devices, and modular rapid color changing. Equipped with remote monitoring and fault diagnosis functions, operators can monitor the equipment's operating status in real time. Compared to traditional spraying equipment, it improves the stability of spraying quality and is widely used in automotive manufacturing, machining, shipbuilding, and other fields. It is especially suitable for modern production lines with stringent requirements for the precision and efficiency of workpiece rust prevention.

[0004] In actual production, workpieces with different materials, shapes, and surface roughness have significantly different requirements for the spraying pressure of anti-rust coatings. Existing equipment lacks automatic pressure sensing and adjustment, requiring operators to manually adjust the pressure based on experience. This is not only cumbersome and inefficient, but also makes it difficult to accurately control pressure changes. Problems such as excessive pressure leading to paint waste and environmental pollution, or insufficient pressure resulting in uneven coating thickness and poor anti-rust effect are common, thus reducing the uniformity of the sprayed surface and affecting the quality of the workpiece. Therefore, a workpiece surface anti-rust spraying equipment is proposed to solve the above problems. Utility Model Content

[0043] Working principle: Cylinder 5 drives transmission rod 6 to move downward. Transmission rod 6 drives sliding disc 9 to move downward along the outer wall of sliding rod 10 through rotating block 7 and rotating block 8. At this time, the rust inhibitor is squeezed and sprayed. Cylinder 5 drives transmission rod 6 to move upward.

[0044] When the liquid inside the nozzle 2 shakes, it squeezes the sliding disc 9, causing the sliding disc 9 to tilt. The sliding disc 9 then drives the sliding ring 12 to tilt synchronously via the sliding rod 10. At this time, the transmission rod 6 and the first rotating block 7 inside the second rotating block 8, and the sliding ring 12 and the first connecting block 14 inside the third rotating block 15 and the second connecting block 17 also begin to rotate in the tilting direction.

[0045] The connecting rod 16 absorbs some of the pressure caused by the tilt. At the same time, some of the springs 13 begin to release their elastic force, and the other springs 13 begin to release their tension. The elastic force and tension act on the sliding ring 12, and the sliding ring 12 begins to move in the opposite tilt direction. The sliding ring 12 drives the sliding disk 9 to move in the opposite tilt direction through the sliding rod 10.
