[0002] In the manufacturing and painting process of van bodies, the spraying process is a crucial step in ensuring their appearance quality. With the continuous development of automated spraying technology, spraying efficiency and coating quality have been significantly improved. To reduce the pollution to the environment and equipment caused by paint splashing and dripping during the spraying process, paint collection trays are usually installed below the spraying area to catch excess paint.
[0003] Existing paint receiving trays are mostly simple flat or shallow groove designs, installed below the spraying station. However, such structures have obvious defects in actual use: when the spraying equipment stops working or the spray gun moves, the paint residue in the spray gun and pipeline easily drips into the paint receiving tray and drips along the edge of the tray under the action of gravity, causing ground pollution and increasing the difficulty of subsequent cleaning. At the same time, existing paint receiving trays lack effective drainage structures, resulting in paint staying on the tray surface for a long time, which easily causes condensation or accumulation, affecting the continuous operation and cleaning and maintenance of the equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3This utility model provides a technical solution: a drip-proof paint receiving tray structure for automatic spraying of a van body, including a paint receiving tray body 1. The edge of the paint receiving tray body 1 is integrally formed with an inwardly inclined guide edge 2. The bottom of the guide edge 2 is provided with an annular liquid collection groove 3. The annular liquid collection groove 3 is connected to an external recovery device through a guide pipe 4. The connection between the guide pipe 4 and the annular liquid collection groove 3 is connected through a connection port. In addition, the middle part of the paint receiving tray body 1 is provided with multiple radially distributed inclined guide ribs 5. The inclined guide ribs 5 extend from the center of the paint receiving tray body 1 towards the edge and are arranged with decreasing height. In addition, two sets of support frames 6 are provided below the paint receiving tray body 1. Each set of support frames 6 consists of two support columns 61 and a crossbeam 62. This structure of the paint receiving tray body 1 This device, placed below the spraying area, collects excess paint dripping during the spraying process. The paint first falls onto the surface of the paint receiving tray 1 and flows radially towards the edge under the action of the inclined guide ribs 5 in the center. Since the height of the inclined guide ribs 5 decreases from the center to the edge, the paint can quickly converge towards the annular collection tank 3. Simultaneously, the inwardly inclined design of the guide edge 2 effectively prevents paint from overflowing from the edge of the tray. The dripping paint is guided by the guide edge 2 into the annular collection tank 3 at the bottom, and then discharged through the guide pipe 4 to an external recycling device, preventing paint from remaining on the surface of the paint receiving tray 1 and causing condensation or accumulation. Meanwhile, the support frame 6 stably supports the entire structure through the support columns 61 and the crossbeams 62, ensuring its positional stability and load-bearing capacity during the spraying operation. This design enhances the paint collection capacity, enabling efficient collection and orderly flow of paint. It solves the problems of existing paint trays, such as paint dripping along the edges and contaminating the ground, long paint retention time, and difficult cleaning, due to their simple structure. The guide edge 2 has an inclination angle of 30°-45°, and the guide edge 2 is connected to the paint tray body 1 via an arc-shaped transition. This structure allows the guide edge 2 to guide the paint dripping to the inward flow when it reaches the edge of the tray, preventing direct dripping and ground contamination. The arc-shaped transition not only strengthens the structural strength between the guide edge 2 and the paint tray body 1 but also reduces paint retention or backflow during flow, allowing the paint to flow more smoothly into the annular collection tank 3, further improving efficiency. To improve the overall anti-drip performance and drainage efficiency of the paint receiving tray, the annular liquid collecting tank 3 has a U-shaped cross-section. Its top opening connects with the lower end of the guide edge 2, and the tank body of the annular liquid collecting tank 3 is arranged in a ring along the edge of the paint receiving tray body 1. This annular liquid collecting tank 3 can fully receive the paint liquid guided down from the guide edge 2. The U-shaped cross-section design effectively increases the volume of the collecting tank and the fluidity of the liquid surface, preventing paint liquid from overflowing. At the same time, the annular arrangement structure allows the paint liquid to collect evenly around the paint receiving tray, avoiding local accumulation. Combined with the liquid guiding pipe 4, it achieves unified discharge, further improving the integrity and efficiency of paint liquid collection. The inclined guide ribs 5 have a trapezoidal cross-section, and adjacent inclined guide ribs 5 form a drainage channel. The surface of the inclined guide ribs 5 is provided with an anti-stick coating.The inclined guide ribs 5 of this structure can guide the paint liquid to flow quickly towards the edge along the drainage channel when it drips onto the middle of the paint receiving tray body 1, using the guide surface formed by the trapezoidal cross-section and inclined arrangement. This prevents the paint liquid from stagnating and accumulating on the tray surface. At the same time, the anti-stick coating effectively reduces the adhesion between the paint liquid and the surface of the guide ribs, making the paint liquid fall more easily, further improving drainage efficiency and reducing the frequency of manual cleaning. The crossbeam 62 is an I-beam structure, with both its front and rear ends located outside the paint receiving tray body 1. The crossbeam 62 in the support frame 6 is equipped with a fixing seat 7, which is fixedly inserted into the crossbeam 62. The liquid guiding tube 4 is fixedly inserted into the fixing seat 7 by clamps. The fixing seat of this structure... 7. This ensures the liquid guide tube 4 is securely installed on the crossbeam 62, guaranteeing its fixed position and preventing it from loosening or shifting due to vibration. It also facilitates installation, disassembly, and maintenance. The support columns 61 are symmetrically welded and fixed to both sides of the bottom of the crossbeam 62. The bottom of the support columns 61 is equipped with adjustable feet 8, which are connected to the support columns 61 via threaded connections. This structure ensures the overall stability of the paint receiving tray body 1 through the stable foundation support of the support columns 61, while the adjustable feet 8 allow for precise adjustment according to the actual flatness of the ground to keep the paint receiving tray level and prevent tilting or instability caused by uneven ground.
[0016] Working principle: When using the anti-drip paint receiving tray structure of this automatic spraying van, first place the paint receiving tray body 1 directly below the spraying area, so that it is within the paint drop area of the spray gun's working range. The inclined guide ribs 5 in the middle of the paint receiving tray body 1 form a guide path when the paint drips. The paint flows along the channel between the inclined guide ribs 5 towards the edge of the paint receiving tray. At the same time, the guide edge 2 further guides the paint in the edge area to the annular collection tank 3 at the bottom. After the paint is collected in the annular collection tank 3, it flows into the guide pipe 4 and is transported to the external recycling device through the guide pipe 4. The crossbeam 62 in the support frame 6 fixes the guide pipe 4 with a clamp through the fixing seat 7 to ensure that the guide pipe 4 remains stable during the transportation process. The adjustable feet 8 at the bottom of the support column 61 are assembled with the column 61 through threaded connection. When installing the paint receiving tray body 1, the height is adjusted according to the ground conditions to keep the entire paint receiving tray structure horizontal and stable, thereby completing a series of tasks.
[0017] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
