Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a spray baffle that improves paint application rate. Background Technology

[0002] For standard bumper products, painting using conventional processes is sufficient to meet aesthetic requirements. However, an increasing number of products feature deep-cavity designs, which increase the difficulty of painting and render conventional processes inadequate for their desired appearance.

[0003] Patent CN201621203083.5 discloses a conveyor chain hook, including a hook body and a profile connecting body with a profile connecting hole. The profile connecting body has a cavity and a hook body connecting hole connected to the cavity. The hook body includes a hook portion and a connecting portion. One end of the hook portion is connected to the connecting portion, and the other end of the connecting portion passes through the hook body connecting hole into the cavity, forming a limiting portion within the cavity to prevent the hook body from detaching from the profile connecting body. A bushing is provided between the hook body connecting hole and the limiting portion. This allows each profile to rotate independently, improving the paint application rate. However, when multiple profiles are fixed, there are paint dead zones on opposite surfaces, making it impossible to guarantee uniform paint application.

[0004] Patent CN201911137363.9 discloses a gas heating device and an air spraying device, including a first chamber with several exhaust holes on its side wall. The first chamber is connected to a gas supply device, which continuously supplies gas to the first chamber until the pressure inside the first chamber reaches a set value, at which point the gas is discharged through the exhaust holes. Due to the limited space of the first chamber and the continuously increasing pressure, the gas enters and comes into contact with the first chamber, rubbing against it and effectively increasing the gas temperature. The entire device has a simple structure and low cost. An air spraying device is also provided, in which gas heated by the gas heating device is input into the spraying body and mixed with paint, effectively improving the paint application rate or the quality of the resulting coating. However, this device suffers from low paint utilization and the problem of spraying dead angles, where paint particles easily rebound to form "paint mist," preventing spraying to concave corners and deep cavities.

[0005] Therefore, existing technologies have technical defects such as paint blind spots and inability to improve the paint coverage rate of deep cavities. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the existing technology and provide a spray baffle that improves the paint application rate, increases the paint application rate of deep cavities, improves process efficiency, and has strong applicability.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] For deep-cavity products, insufficient paint coverage may occur during the painting process. This can be addressed by adding a spray baffle to improve the product's pass rate.

[0009] This utility model provides a spray baffle to improve paint application rate. The spray baffle matches the deep cavity shape of the product. The edge of the spray baffle is set 2mm away from the edge of the deep cavity, and the thickness is 2.0mm to 3.0mm. The spray baffle is provided with mounting holes, and a buckle is provided at the root of the deep cavity of the product. The spray baffle is fixed to the root of the deep cavity of the product by the buckle. During painting, a paint swirling space is formed to improve the paint coverage of the sidewall of the deep cavity.

[0010] Furthermore, the spray baffle is made of PP+EPDM-T10 / 20 / 30 or mica board. These materials can improve the paint application rate in deep cavity locations.

[0011] Furthermore, the number of the buckles is 2 to 3.

[0012] Furthermore, the width of the buckle matches the size of the mounting hole.

[0013] Furthermore, the spraying baffle is provided with at least four mounting holes.

[0014] Furthermore, the depth of the deep cavity ranges from 10mm to 30mm and is located in the air intake channel, reflector, or reversing light area of ​​the product.

[0015] Furthermore, the mounting hole is elliptical.

[0016] Furthermore, the surface of the spray baffle is provided with micron-level rough texture (Ra 5~20μm) to increase the adhesion of paint and reduce paint mist rebound.

[0017] Furthermore, the spraying baffle adopts a segmented and detachable structure, with each segment fixed by magnetic connection or plug-in buckle to adapt to the deep cavity spraying requirements of different depths.

[0018] Furthermore, the edge of the spray baffle is provided with an arc-shaped transition structure with a curvature radius R of 3-5mm, which is used to guide the paint airflow to turn smoothly and reduce paint mist turbulence loss.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) Improve paint coverage in deep cavities. By designing a baffle to match the shape of the deep cavity, the problem of insufficient paint coverage in the deep cavity area in traditional spraying processes is effectively solved. A 2mm gap is maintained between the baffle and the edge of the deep cavity, forming an ideal paint swirling space, allowing the paint to evenly cover the sidewalls of the deep cavity. Using PP+EPDM series materials (T10 / T20 / T30) or mica sheets ensures both the mechanical strength of the baffle and meets the temperature resistance requirements of the spraying process.

[0021] (2) Improved process efficiency. The baffle adopts a detachable design, which can be recycled and reused after spraying, significantly reducing production costs and material waste. It can be quickly installed before spraying and easily removed after spraying without affecting the production cycle, making it suitable for mass production environments.

[0022] (3) High applicability. The baffle contour perfectly matches the three-dimensional shape of the product's deep cavity, ensuring that the original structure of the product is not affected after installation, while providing the best spraying effect. The oval mounting hole design allows the installation position to be adjusted according to the product structure, and with 2-3 clips, a stable fixation can be achieved, making it highly versatile.
