[0026] The paint blocking seat 3 is provided with a groove, in which a baffle 31 is embedded. Compression springs 32 are arranged at four corners of the baffle 31 , and the other end of the compression spring 32 abuts against the inner wall of the groove of the baffle 31 .
[0027] In this embodiment, in actual use, through the mutual movement and coordination of multiple components within the spray assembly 2, the spray device of the present application can stir and re-suspend the sediment and stratified materials in the paint to achieve uniform mixing, ensuring that the composition of the paint remains consistent throughout the spraying process. This can avoid problems such as uneven color, gloss and thickness of the coating and improve the coating quality and appearance.
[0028] Furthermore, the paint blocking seat 3 and the baffle 31 can effectively block the splashing of paint during spraying, thereby preventing the spray paint from splashing to areas that do not need spraying, thereby keeping the working environment clean and reducing subsequent cleaning work. At the same time, the baffle 31 is limited by the compression spring 32, so that the baffle 31 can be quickly removed in the paint blocking seat 3, thereby facilitating the replacement and cleaning of the baffle 31.
[0029] Specifically, refer to Figure 2-3 The spraying assembly 2 also includes a base arranged on the mounting plate 26, on which a pump 25 is mounted, and an output end of the pump 25 is connected to a conduit 24, which extends to the mixing box 23 and is connected thereto.
[0030] In this embodiment, in actual use, the user connects the pump 25 to a power source, and through the connection between the pump 25 and the conduit 24, the pump 25 can extract the paint in the paint supply box 22 into the transmission pipe 27 for discharge. In a preferred embodiment, in order to improve the uniform extraction of the paint, the user can also use a heating belt to heat the paint supply box 22 and the mixing box 23, so that the paint is always in a flowing state, thereby improving the spraying efficiency.
[0031] Specifically, refer to Figure 2-3 The output end of the pump 25 is connected to a transmission pipe 27 , which passes through the mounting plate 26 and extends to be connected to a feed pipe 28 , on which a plurality of nozzles 29 are connected.
[0032] In this embodiment, when the paint is extracted through the input end of the pump 25, the output end of the pump 25 is connected to the transmission pipe 27, so that the paint can be discharged into the feeding pipe 28 through the transmission pipe 27 and sprayed through a plurality of nozzles 29. In a preferred embodiment, the nozzle 29 is a mist nozzle, so that the nozzle 29 has a wider spray range when spraying.
[0033] Specifically, refer to Figure 2-3 The paint feeding box 22 is connected to a feeding port 221 , and a valve member is mounted on the feeding port 221 .
[0034] In this embodiment, in actual use, the feed port 221 can be used to inject paint into the paint feeding box 22 and the mixing box 23, and the valve member can be used to inject the paint quantitatively.
[0035] Specifically, refer to Figure 1 and Figure 4 The baffle plate 31 is disposed on the opposite side of the plurality of nozzles 29 , and the baffle plate 31 is an acrylic plate with a smooth surface treatment.
[0036] In this embodiment, the baffle 31 made of acrylic material can be used as a physical barrier to block the paint during the spraying process on one side of the baffle 31 to prevent it from splashing to other areas, thereby helping to reduce paint waste during the spraying process and reducing cleaning work. The smooth treatment of the baffle 31 can also improve the cleaning of the baffle 31.
[0037] Specifically, refer to Figure 1 and Figure 4 A top plate 4 is installed between the paint blocking seat 3 and the spraying assembly 2. The top plate 4 is arranged parallel to the upper end surface of the conveying mechanism 1. A guide rod cylinder 5 is installed on the top plate 4. The output end of the guide rod cylinder 5 passes through the top plate 4 and is connected to a positioning plate 6.
[0038] In this embodiment, in actual use, the user places the workpiece to be sprayed on the conveying mechanism 1, and then starts the conveying mechanism 1 to move. When the workpiece moves to the side of the spraying component 2, the user controls the guide rod cylinder 5 to drive, so that the output end of the guide rod cylinder 5 drives the positioning plate 6 to press down until the positioning plate 6 is tightly against the workpiece, thereby limiting the workpiece. By limiting the workpiece, the spraying stability can be improved.
[0039] The spraying device in the automobile painting line of the utility model:
[0040] Step 1: When the user is spraying the automobile workpiece, the paint to be used is poured into the paint feeding box 22 through the feed port 221, and the paint feeding box 22 and the stirring box 23 are connected to each other so that the paint can be filled into the paint feeding box 22 and the stirring box 23 through the feed port 221. When the paint pouring is completed, the user connects the power supply to the rotating motor 210 through the wire and drives the rotating motor 210 to output. At this time, the driving of the rotating motor 210 can drive the transmission shaft 211 and the stirring blade 212 to rotate in the paint feeding box 22 and the stirring box 23. The stirring blade 212 is continuously rotated to achieve uniform stirring of the paint;
[0041] Step 2: After the paint is stirred by the stirring blade 212, the user connects the pump 25 to a power source, and the pump 25 is connected to the conduit 24, so that the pump 25 can extract the paint in the paint inlet box 22 to the transmission pipe 27 and finally spray it out through the nozzle 29;
[0042] Step 3: The user places the workpiece to be sprayed on the conveying mechanism 1, and then starts the conveying mechanism 1 to move. When the workpiece moves to the side of the spraying component 2, the user controls the guide rod cylinder 5 to drive, so that the output end of the guide rod cylinder 5 drives the positioning plate 6 to press down until the positioning plate 6 is tightly against the workpiece to limit the workpiece. At this time, the spraying of the paint by the spraying component 2 can realize the spraying operation of the automobile workpiece. At the same time, the sprayed paint can be blocked by the baffle 31 to prevent the paint from splashing.
