Description

TECHNICAL FIELD

[0001] The utility model belongs to metal fittings processing technical field, specifically relates to a surface spraying equipment for metal fittings processing. BACKGROUND

[0002] In today's industrial production field, the wide application of metal fittings puts forward higher and higher requirements on its quality and performance. As the key process for improving the corrosion resistance, decoration and wear resistance of metal fittings, the technology and equipment of surface spraying directly affect the quality of the final product.

[0003] Traditional metal fitting surface spraying operation is often carried out in an environment lacking effective protective facilities. During the spraying process, a large amount of paint mist will diffuse in the air. These paint mists contain harmful chemical substances such as volatile organic compounds (VOCs), which not only cause serious pollution to the atmospheric environment, but also gradually accumulate in the body under the long-term respiratory exposure of the operators, causing various respiratory diseases, allergic reactions, and even more serious chronic health problems such as cancer, etc.

[0004] In terms of the control of the distance between the spray head and the surface of the metal fitting, the traditional spraying equipment has great limitations. The surface of the metal fitting is usually irregular, full of various protrusions, depressions, grooves and curved surfaces. But the traditional equipment cannot sense and adapt to these surface changes in real time, causing the distance between the spray head and the surface of the fitting to fluctuate frequently. When the spray head is too close, the paint liquid may accumulate in the local area, forming an excessively thick coating, resulting in defects such as sagging and dripping, not only wasting the paint, but also increasing the difficulty and cost of subsequent processing; when the spray head is too far away, the spraying speed and pressure of the paint liquid will decrease significantly, resulting in a thin coating and reduced adhesion, which cannot achieve the expected protection and decoration effect.

[0005] Therefore, we propose a surface spraying equipment for metal fitting processing, which not only protects people during spraying, improves safety, but also ensures that the distance between the spray head and the metal fitting remains constant, thereby improving the uniformity and effect of spraying.

In this way, the atomized liquid generated in the paint spraying process is effectively limited in the closed space, the outward diffusion of the atomized liquid is greatly prevented, and the potential harm to the surrounding environment and the operator's body is significantly reduced, then the transverse moving assembly is started, which drives the connecting plate to accurately displace in the horizontal direction along the first sliding groove, and simultaneously, the longitudinal moving assembly also starts to work and drives the connecting rod to accurately move in the vertical direction in the hollow shell. Through the cooperative operation of the transverse moving assembly and the longitudinal moving assembly, the spray head connected to the longitudinal moving assembly can reach any position on the surface of the metal accessory, and in the moving process, the elastic assembly plays a key role when encountering irregular shapes on the surface of the metal accessory. Due to the protrusions or depressions on the surface of the metal accessory, different forces are generated on the roller in different directions. The elastic assembly can generate corresponding expansion or rebound according to the changes of the forces. When the protruding part is encountered, the elastic assembly is compressed, so that the roller and the spray head can move upward, and when the recessed part is encountered, the elastic assembly is stretched, so that the roller and the spray head are pushed to move downward. In this way, the roller is always tightly attached to the irregular surface of the metal accessory, and the distance between the spray head and the metal accessory is always kept constant. Under the condition that the distance between the spray head and the metal accessory is constant, the pump body is started, the pump body draws and pressurizes the paint spraying liquid in the liquid storage cylinder through the connecting pipe, and then uniformly sprays the paint spraying liquid on the surface of the metal accessory from the spray head. Since the distance between the spray head and the metal accessory is constant, the paint spraying liquid can reach each part of the metal accessory at the same speed and pressure, so that uniform and high-quality spraying effect is realized. The device not only can protect during paint spraying and improve the safety of people, but also can ensure that the distance between the spray head and the metal accessory is constant, thereby improving the uniformity and effect of spraying.

[0036] The working principle of the utility model is as follows: firstly, the prepared paint liquid is carefully injected into the liquid storage cylinder 15, ensuring sufficient liquid supply, then the metal fittings to be sprayed are placed between the two fixed discs 8, the telescopic assembly is started, the telescopic assembly drives the fixed disc 8 to move along the preset direction, gradually approaching the metal fittings from both sides until tightly fixing it, in the process, the roller 13 is fully attached to the surface of the metal fittings, then the rotating assembly drives the connected frame 7 to rotate, so that the connected frame 7 drives the semicircular protective plate 5 to smoothly rotate in the arc-shaped groove 4, when the semicircular protective plate 5 is completely rotated in place, it forms a closed protective shell together with the semicircular plate 3, tightly surrounding the area where the paint spraying operation is being carried out. In this way, the atomized liquid generated in the paint spraying process is effectively limited in this closed space, greatly preventing its outward dispersion, thereby significantly reducing the potential harm to the surrounding environment and the operator's body, then the transverse moving assembly is started, which drives the connecting plate 9 to accurately displace in the horizontal direction along the first sliding groove 2, at the same time, the longitudinal moving assembly also starts to work, driving the connecting rod 11 to accurately move in the vertical direction inside the hollow shell. Through the coordinated operation of the transverse moving assembly and the longitudinal moving assembly, the spray head 14 connected to the longitudinal moving assembly can reach any position on the surface of the metal fittings, in the moving process, when encountering irregular shapes on the surface of the metal fittings, the elastic assembly plays a key role. Due to the protrusions or depressions on the surface of the metal fittings, different forces will be generated on the roller 13. The elastic assembly can produce corresponding stretching or rebound according to the changes of these forces. When encountering protruding parts, the elastic assembly is compressed, enabling the roller 13 and the spray head 14 to move upward, when encountering recessed parts, the elastic assembly stretches, pushing the roller 13 and the spray head 14 to move downward. In this way, the roller 13 is always tightly attached to the irregular surface of the metal fittings, thereby ensuring that the distance between the spray head 14 and the metal fittings always remains constant. Under the condition that the distance between the spray head 14 and the metal fittings remains constant, the pump body is started, which draws and pressurizes the paint liquid in the liquid storage cylinder 15 through the connecting pipe, and then uniformly sprays it onto the surface of the metal fittings from the spray head 14. Since the distance between the spray head 14 and the metal fittings is constant, the paint liquid can reach all parts of the metal fittings at the same speed and pressure, thereby achieving uniform and high-quality spraying effect. The device not only can protect during paint spraying, improve people's safety, but also ensures that the distance between the spray head 14 and the metal fittings remains constant, thereby improving the uniformity and effect of spraying.
